OPINION

1
P&J Energy, Inc.; Paula Watson Lakamp; Lawrence B. Watson, individually and as trustee of the
Watson Family Trust; and Leslie Watson Fisette, collectively “the Watson Group” are also Appellees to
this action. However, Appellant Perdido Properties LLC does not challenge the summary judgment granted
in favor of the Watson Group.
 This is an appeal from orders granting summary judgment in favor of Appellee
Devon Energy Production Company, L.P. It involves claims for the nonpayment of
mineral royalties to Leon C. Smitherman, Jr. and Paul H. Bremer, Jr. Appellant,
Perdido Properties LLC, brought the underlying suit on behalf of Smitherman Jr.
and Bremer Jr. as their attorney-in-fact. The trial court determined that Smitherman,
Jr. and Bremer, Jr. were not entitled to recover under any theory alleged. In four
issues, Perdido challenges this determination. We affirm in part, and reverse and
remand in part.
Background Facts
This case concerns the ownership of a royalty interest in Ector County known
as the “Bray Interest” that is attributable to Pauline Bray. On August 27, 1945,
Raymond D. Savageau conveyed a royalty interest in certain tracts of land to Ross
Bray in Ector County.2 Ross Bray died before the relevant events in this case. In
his last will and testament, Ross Bray bequeathed the residuary of his estate, which
included the Bray Interest, as follows: (1) 75% to Pauline Bray (Bray’s wife);
(2) 12.5% to Ethel B. McConnell (Bray’s sister); and (3) 12.5% to Mable B. Renney
(Bray’s sister).
On September 2, 1969, Pauline Bray died intestate in Denver. She was
survived by her husband at the time, Leon Smitherman, Sr., and her siblings, Clair
Bremer and William Watson a/k/a William Doane Watson. Smitherman Jr. claims
through Leon Smitherman and Bremer Jr. claims through Clair Bremer.
In 2008, Devon became the operator on the leases covering the Bray Interest.
Devon remained as the operator on those leases until 2016. In 2009, Devon obtained

2
Savageau conveyed the following royalty interest: (1) an undivided 304/100,000 royalty interest
in Section 48, Block 42, Township 2 South; (2) an undivided 168/100,000 interest in Section 45, Block 42,
Township 2 South, Texas and Pacific Railway Company Original Grantee; (3) an undivided 174/100,000
royalty interest in Sections 46 and 47, Block 42, Township 2 South, Texas and Pacific Railway Company
Original Grantee; and (4) an undivided 174/100,000 royalty interest in Sections 1, 2, 3, 4, 10, 14, 15, 16
and 23 in Block 42 Township 3 South, Texas and Pacific Railway Company Original Grantee.

a title opinion that linked Pauline Bray to the Bray Interest. Devon held the royalties
attributable to the Bray Interest in suspense because it was unable to determine the
identity of Pauline Bray’s heirs.
On September 29, 2010, Enerlex, Inc. e-mailed Devon that it “[had] acquired
¼ of the right, title and interest of Pauline W. Bray from her heir, William Doane
Watson.” Enerlex attached a deed where William Watson conveyed all of his
interest in Ector County to Enerlex. Enerlex also attached a copy of a recorded
affidavit of heirship that Anita Watson executed. The affidavit of heirship reflected
that Pauline Bray died intestate and that, at the time of her death, she was survived
by her husband Leon Smitherman Sr.; her brother, William Watson; and her sister,
Clair Bremer.
In October 2010, William Watson’s daughter, Leslie Watson Fisette,
contacted Devon. In their conversation, Fisettee notified Devon that there may be
an issue regarding the validity of William Watson’s deed to Enerlex. During this
time, Devon continued to hold the proceeds attributable to the Bray Interest in
suspense.
In April 2011, attorney Jacob De Leon, on behalf of William Watson, sent a
demand letter to Devon. In De Leon’s letter to Devon, he included the following
instruments: (1) a power of attorney signed by Lawrence Watson on behalf of his
father, William Watson; (2) the Anita Watson affidavit of heirship; and (3) tax
records from Ector County. De Leon demanded that Devon pay the proceeds due to
the “heirs of Pauline Bray” to William Watson and De Leon’s law firm. In spite of
De Leon’s demand letter, Devon continued to hold the proceeds attributable to the
Bray Interest in suspense.
Following Devon’s refusal to distribute the Bray Interest proceeds, Lawrence
Watson, as court appointed conservator of William Watson, filed suit in the 244th
District Court of Ector County against both Devon and Enerlex seeking to set aside
3
the 2009 deed. Lawrence Watson pleaded that, at the time William Watson entered
into the 2009 deed, William Watson was “legally incapacitated and legally
incompetent and has been legally incapable of entering into . . . deeds since at least
2007.”
On October 2, 2012, William Watson, Devon, and Enerlex entered into an
agreed judgment. The Agreed Judgment set aside the 2009 deed from William
Watson to Enerlex, and it required that Lawrence Watson, on behalf of William
Watson, deliver “properly drafted division orders” to Devon. William Watson’s
division order reflected that 100% of the Bray Interest was payable to William
Watson and De Leon.3 After receiving the division orders, Devon began paying the
proceeds that it had been holding in suspense. Devon paid William Watson
approximately $557,299.48 between March 3, 2013 and October 3, 2013.4 Devon
paid De Leon approximately $224,109.69 between March 3, 2013, and October 3,
2013.
In November 2013, De Leon assigned his interest in the Bray Interest to P&J
Energy. Following this assignment, Devon and P&J Energy executed new division
orders reflecting the assignment. Shortly after Devon and P&J Energy executed the
new division order, William Watson passed away. William Watson’s interest in the
Bray Interest transferred to the Watson Group. Devon paid the Watson Group
according to their division orders until October 15, 2016. In total, Devon paid the
Watson Group and De Leon $1,093,347.27 for payments attributable to the Bray
Interest.
On November 11, 2016, Perdido’s attorney sent Devon a demand letter on
behalf of Smitherman Jr. (hereinafter Smitherman) claiming that Smitherman owned

3
William Watson’s division order reflected that he was entitled to 66.67% of the Bray Interest and
that De Leon was entitled to 33.33% of the interest.

50% of the Bray Interest. In the letter, Perdido asserted that Smitherman’s father
was married to Pauline Bray at the time of her death, and because of intestacy laws,
his father was entitled to half of her interest. Perdido further claimed that after the
deaths of Smitherman’s father and his father’s widow, he was entitled to half of the
Bray Interest. On December 12, 2016, Devon and Smitherman entered into a
Release Agreement pertaining to the unpaid royalties. Under the Release
Agreement, Devon paid Smitherman $50,000.
On February 16, 2017, Perdido’s attorney sent Devon a demand letter on
behalf of Bremer Jr. (hereinafter Bremer) asserting that Bremer owned 25% of the
Bray Interest. In the letter, Perdido claimed that Bremer was entitled to 25% of the
Bray Interest because his mother, Clair Bremer, survived her sister, Pauline Bray.
Perdido further claimed that Bremer inherited 25% of the Bray Interest through his
parents’ wills. Over the next several weeks, Devon and Perdido’s counsel
communicated via email concerning potential release agreements with respect to
Bremer’s claim for unpaid royalties. However, the parties did not enter into a release
agreement. Ultimately, Devon did not pay Smitherman or Bremer any royalties
(aside from the $50,000 that Smitherman received under the Release Agreement).
On behalf of Smitherman and Bremer, Perdido filed suit on October 3, 2017,
against Devon and the Watson Group. Perdido asserted a cause of action against
Devon based on the contention that Devon had failed to pay the royalties due
Smitherman and Bremer under the terms of the oil and gas leases for the subject
properties. Perdido also asserted a claim under the Natural Resources Code against
Devon for the nonpayment of royalties, and a claim for breach of fiduciary duty.
Perdido asserted an “alternative claim” against the Watson Group for unjust
enrichment and money had and received based upon the contention that the Watson
Group received payments from Devon that should have been made to Smitherman
and Bremer.
5
 Devon responded to Perdido’s suit by asserting limitations as an affirmative
defense. In this regard, Perdido filed suit more than four years after Devon began to
distribute royalties that it had held in suspense. Devon also asserted that
Smitherman’s claims were released by virtue of the release agreement. The Watson
Group also asserted limitations as an affirmative defense. Devon asserted a cross-
claim against the Watson Group on the basis that Devon overpaid royalties to the
Watson Group. Devon also asserted a cause of action for breach of contract against
Perdido and Smitherman for breach of the release agreement.
The Watson Group sought and obtained a partial summary judgment on
Perdido’s claims based on limitations. Devon also sought and obtained a partial
summary judgment based on limitations to Perdido’s claims with respect to claims
accruing before October 3, 2013. The trial court denied Perdido’s competing motion
for summary judgment wherein it sought judgment as a matter of law against Devon
for nonpayment of royalties.
Devon subsequently filed a motion for summary judgment on the
remainder of Perdido’s claims. Devon sought a traditional summary judgment under
Gavenda v. Strata Energy, Inc.5 on the basis that Perdido’s claims on behalf of
Smitherman and Bremer were precluded because Devon paid the royalties
attributable to their respective interests under a division order. Devon also asserted
that all of Smitherman’s and Bremer’s claims were barred by limitations, and that
Perdido had no evidence to support its claims for fraudulent inducement or
conspiracy. Perdido also filed a second motion for summary judgment asserting that
the holding in Gavenda did not apply to the facts in this case. The trial court granted
Devon’s subsequent motion for summary judgment and denied Perdido’s subsequent
motion for summary judgment in an order that disposed of the entire case.

 Analysis
On appeal, Perdido presents four issues in which it challenges the trial court’s
summary judgment in favor of Devon. As previously noted, Perdido and Devon
filed competing motions for summary judgment. When parties file competing
motions for summary judgment and the trial court grants one party’s motion and
denies the other’s motion, we review the summary judgment evidence presented by
both parties and determine all the issues presented. Valence Operating Co. v.
Dorsett, 164 S.W.3d 656, 661 (Tex. 2005).
We review the trial court’s grant of summary judgment de novo. Lujan v.
Navistar, Inc., 555 S.W.3d 79, 84 (Tex. 2018) (citing Provident Life & Accident Ins.
Co. v. Knott, 128 S.W.3d 211, 215 (Tex. 2003)). When the trial court’s order does
not specify the grounds for its summary judgment, we will affirm the summary
judgment if any of the theories are meritorious. Knott, 128 S.W.3d at 216.
Generally, if a party moves for summary judgment on both traditional and no-
evidence grounds, we first consider the no-evidence motion. Lightning Oil Co. v.
Anadarko E&P Onshore, LLC, 520 S.W.3d 39, 45 (Tex. 2017).
After an adequate time for discovery, a party may move for summary
judgment on the ground that there is no evidence of one or more essential elements
of a claim or defense on which an adverse party would have the burden of proof at
trial. TEX. R. CIV. P. 166a(i). We review a no-evidence motion for summary
judgment under the same legal sufficiency standard as a directed verdict.
Merriman v. XTO Energy, Inc., 407 S.W.3d 244, 248 (Tex. 2013). Under this
standard, the nonmovant has the burden to produce more than a scintilla of evidence
to support each challenged element of its claims. Id. Evidence is no more than a
scintilla if it is “so weak as to do no more than create a mere surmise or suspicion”
of a fact. King Ranch, Inc. v. Chapman, 118 S.W.3d 742, 751 (Tex. 2003) (quoting
Kindred v. Con/Chem, Inc., 650 S.W.2d 61, 63 (Tex. 1983)).
7
 A party moving for traditional summary judgment bears the burden of proving
that there is no genuine issue of material fact and that it is entitled to judgment as a
matter of law. TEX. R. CIV. P. 166a(c); Nassar v. Liberty Mut. Fire Ins. Co., 508
S.W.3d 254, 257 (Tex. 2017). To be entitled to a traditional summary judgment, a
defendant must conclusively negate at least one essential element of the cause of
action being asserted or conclusively establish each element of an affirmative
defense. Sci. Spectrum, Inc. v. Martinez, 941 S.W.2d 910, 911 (Tex. 1997).
Evidence is conclusive only if reasonable people could not differ in their
conclusions. City of Keller v. Wilson, 168 S.W.3d 802, 816 (Tex. 2005). If the
movant initially establishes a right to summary judgment on the issues expressly
presented in the motion, then the burden shifts to the nonmovant to present to the
trial court any issues or evidence that would preclude summary judgment. See City
of Houston v. Clear Creek Basin Auth., 589 S.W.2d 671, 678–79 (Tex. 1979).
I. Appellant’s Statutory Claim for Nonpayment of Royalties
In its first issue, Perdido contends that the trial court erroneously granted
Devon’s summary judgment motion on Smitherman’s and Bremer’s claims under
Section 91.402 of the Texas Natural Resources Code for nonpayment of royalties.
See TEX. NAT. RES. CODE ANN. § 91.402 (West Supp. 2022). Perdido asserts that
Devon violated Section 91.402 of the Natural Resources Code by paying the entire
Bray Interest to De Leon and the Watson Group. In presenting this issue, Perdido
seeks to overcome two legal defenses presented by Devon to Smitherman’s and
Bremer’s statutory claim for unpaid royalties. As set out below, these legal defenses
would entirely preclude Smitherman’s and Bremer’s claims for unpaid royalties
irrespective of the timeliness of Perdido’s suit. Furthermore, these legal defenses
would apply equally to Smitherman’s and Bremer’s claims.
“A payee has a cause of action for nonpayment of oil or gas proceeds or
interest on those proceeds as required in Section 91.402 . . . .” Id. § 91.404(c) (West
8
2011). In order to prevail on a cause of action for nonpayment of royalties, Perdido
must show that (1) both Smitherman and Bremer are payees; (2) Devon is a payor;
(3) Devon failed to pay the proceeds attributable to the Bray Interest to either
Smitherman or Bremer; (4) Smitherman and Bremer gave written notice by mail of
Devon’s alleged failure to pay their royalties; (5) Devon did not pay the royalties
within thirty days of receiving written notice; and (6) Smitherman and Bremer were
injured as a result of nonpayment. See Ellison v. Three Rivers Acquisition, LLC, 609
S.W.3d 549, 567 (Tex. App.—Corpus Christi–Edinburg 2019), rev’d on other
grounds sub nom. Concho Res., Inc. v. Ellison, 627 S.W.3d 226 (Tex. 2021).
The summary judgment evidence includes a judgment declaring heirship for
Pauline Bray. In the judgment, the County Court at Law of Ector County declared
the heirs of Pauline Bray to be Bremer at one-quarter interest, William Doane
Watson at one-quarter interest, and Smitherman at one-half interest. This judgment
declaring heirship establishes that both Smitherman and Bremer are entitled to a
percentage of the proceeds attributable to the Bray Interest, and thus they are payees.
The summary judgment evidence also established that Devon was responsible
for paying out the proceeds attributable to the Bray Interest and that Devon paid all
the proceeds to De Leon and the Watson Group. The summary judgment evidence
further established that both Smitherman and Bremer sent Devon demand letters and
that Devon failed to pay within thirty days of receiving notice. Devon does not
contest this summary judgment evidence; rather, Devon contends that its
nonpayment was excused because of the agreed judgment in the suit involving
Enerlex, and that Gavenda bars Appellant’s suit against Devon for unpaid royalties.
A. Enerlex Judgment
Devon’s first legal justification for the nonpayment of royalties to
Smitherman and Bremer is the agreed judgment involving Enerlex. In September of
2009, William Watson was diagnosed with dementia. He subsequently executed a
9
mineral deed on November 13, 2009, conveying all of his mineral interest in Ector
County to Enerlex. In 2011, Lawrence Watson, as William Watson’s court-
appointed conservator, sued both Enerlex and Devon. Watson’s lawsuit sought to
cancel, set aside and declare void a fraudulent and forged mineral deed
purportedly executed by William Doane Watson in favor of Enerlex . . .
at a time that William Doane Watson was legally incompetent, legally
and mentally incapacitated, and legally incapable of having the
requisite intent to . . . execute any conveyance to Enerlex . . . .
In October 2012, the 244th District Court of Ector County entered an agreed
judgment executed by attorneys for Lawrence Watson, Enerlex, and Devon. The
agreed judgment set aside William Watson’s conveyance to Enerlex. The agreed
judgment further provided that:
All right, title and interest to the property in the purported conveyance
[be] immediately restored ab initio and to be held by Lawrence B.
Watson, as Court Appointed Conservator of William Doane Watson,
an incapacitated Person. This Agreed Judgment instrument fully,
finally and immediately adjudicates the ownership, right, title and
interests described herein.

The Agreed Judgment further provided that Lawrence Watson would execute and
deliver “properly drafted division orders” to Devon and that Devon would provide
Lawrence Watson “all funds in their possession payable to the interest of William
Doane Watson.”
Devon contends that the agreed judgment determined that all of Pauline
Bray’s interest passed to William Watson. Devon further asserts that Appellant’s
claim for nonpayment of royalties is an impermissible collateral attack on the agreed
judgment.
We first observe that the Enerlex litigation was a suit to set aside the
conveyance from William Watson to Enerlex. It was not a proceeding to declare
heirship with respect to Pauline Bray as contemplated by the Texas Estates Code.

10
See TEX. EST. CODE ANN. § 202.001 (West 2020). In this regard, the unknown heirs
of Pauline Bray were not made parties to the litigation, and an attorney ad litem was
not appointed by the trial court to represent the unknown heirs—both of which are
statutory requirements of a proceeding to declare heirship. See id. §§ 202.008, .009.
Furthermore, “[e]xclusive original jurisdiction to determine heirship is conferred
upon the county court sitting in probate, and the district court has no such original
jurisdiction.” Thomas v. Tollon, 609 S.W.2d 859, 860 (Tex. Civ. App.—Houston
[14th Dist.] 1980, writ ref’d n.r.e.); see Estate of Torrance v. State, 812 S.W.2d 393,
396 (Tex. App.—El Paso 1991, no writ) (addressing the exclusive jurisdiction of the
county courts of Ector County to determine heirship).
The Enerlex judgment does not provide that William Watson owned the entire
Bray Interest. The judgment restored William Watson’s ownership in the interest
that he conveyed to Enerlex, but it did not address what he received from Pauline
Bray. As we noted above, Enerlex had previously advised Devon that it had acquired
one-quarter of Pauline Bray’s interest by virtue of its deed from William Watson.
Furthermore, the Enerlex judgment was an agreed judgment. Agreed judgments are
construed in the same manner that contracts are. Gulf Ins. Co. v. Burns Motors, Inc.,
22 S.W.3d 417, 422 (Tex. 2000). An agreed judgment is “contractual in nature and
in effect is a written agreement between the parties as well as an adjudication.”
Avila v. St. Luke’s Lutheran Hosp., 948 S.W.2d 841, 854 (Tex. App.—San Antonio
1997, pet. denied) (citing Wagner v. Warnasch, 295 S.W.2d 890, 893 (Tex. 1956)).
However, agreed judgments are “binding only as to the parties to the agreement and
not as to any other party . . . unless the other parties are bound by the doctrine of
virtual representation.” Id. at 854 (citing Lowe v. Ragland, 297 S.W.2d 668, 673
(Tex. 1957); Sawyer v. Smith, 552 S.W.2d 936, 940 (Tex. App.—Waco 1977, writ
ref’d n.r.e.)). “A person who is not a party or privy to a party to an action in which
a valid judgment . . . is rendered is not bound by . . . an adjudication upon any matter
11
decided in the action.” Id. at 854–55 (citing Blonder-Tongue Lab. Inc. v. Univ. of
Ill. Found., 402 U.S 313, 322 (1971)). “[O]ne not before the court cannot be bound
by any judgment entered.” Id. at 855.
Neither Smitherman nor Bremer were parties to the Enerlex lawsuit or the
agreed judgment that resulted from it. Furthermore, there is no contention that either
of them were in privity with any of the parties to the agreed judgment or that
Smitherman and Bremer were bound to the agreed judgment by the doctrine of
virtual representation. Therefore, neither Smitherman nor Bremer are bound by the
agreed judgment as Devon contends, and it does not preclude Appellant’s claim for
nonpayment of royalties.
B. Applicability of Gavenda
Devon next contends that Smitherman and Bremer cannot pursue a claim for
nonpayment of royalties against Devon under Gavenda because Devon made
payments according to division orders. Signed division orders create a contractual
relationship. See Rogers v. Ricane Enters., Inc., 884 S.W.2d 763, 770 (Tex. 1994).
“[Division orders] are binding between the parties ‘for the time and to the extent that
they have been or are being acted on and made the basis of settlements and payments,
and from the time that notice is given that settlements will not be made on the basis
provided in them, they cease to be binding.’” Cabot Corp. v. Brown, 754 S.W.2d
104, 107–08 (Tex. 1987) (quoting Exxon Corp. v. Middleton, 613 S.W.2d 240, 250–
51 (Tex. 1981)).
Division orders are “the mechanism for payment to a payee of its share of oil
and gas proceeds.” Prize Energy Res., L.P. v. Cliff Hoskins, Inc., 345 S.W.3d 537,
560 (Tex. App.—San Antonio 2011, no pet.), abrogated on other grounds by Nath v.
Tex. Children’s Hosp., 576 S.W.3d 707 (Tex. 2019). The Natural Resources Code
permits a payor to require a signed division order “[a]s a condition for the payment
of proceeds from the sale of oil and gas production.” NAT. RES. § 91.402 (c)(1).
12
“[T]he statute places the burden on the payor to submit a division order to the payee
for its signature; it is not the royalty owner or mineral interest owner’s burden to
draft its own division order, sign it, and submit it to the payor.” Prize Energy Res.,
L.P., 345 S.W.3d at 560 (citing NAT. RES. § 91.402 (c)(1)); see Circle Ridge Prod.,
Inc. v. Kittrell Fam. Mins., LLC, No. 06-13-00009-CV, 2013 WL 3781367, at
*6 (Tex. App.—Texarkana July 17, 2013, pet. denied) (mem. op.); Jones v. Clem,
No. 11-10-00123-CV, 2012 WL 1069168, at *4 (Tex. App.—Eastland Mar. 29,
2012, no pet.) (per curiam) (mem. op.) (“[I]n order to rely upon a division order, [the
payor] had the obligation to submit it to the payees for signature.”).
The Texas Supreme Court described the issue before the court in Gavenda as
follows: “This oil and gas case concerns the effect of division and transfer orders.
The issue is whether division and transfer orders are binding until revoked when an
operator who prepares erroneous orders underpays royalty owners, retaining part of
the proceeds for itself.” 705 S.W.2d at 690. The Gavenda family conveyed a tract
of land to the Feinsteins, reserving a fifteen-year, one-half nonparticipating royalty
interest. Id. The Feinsteins subsequently conveyed the property, subject to the
Gavendas’ reservation, to Blaha. Id. at 691. Blaha then executed an oil and gas
lease providing for a one-eighth royalty. Id. Strata Energy erroneously prepared
division orders that provided that the Gavendas reserved a one-sixteenth
nonparticipating royalty interest rather than a one-half nonparticipating royalty
interest. Id. The Gavendas signed the erroneous division orders submitted to them
by Strata Energy. Id. As a result of the erroneous division orders, Strata Energy
underpaid the Gavendas’ royalty by seven-sixteenths, which amounted to $2.4
million. Id.
The Gavendas filed suit against Strata Energy to recover the underpaid
royalties. Id. Strata Energy asserted, and the trial court and court of appeals agreed,

13
that the division orders executed by the Gavendas were binding until revoked,
thereby precluding a recovery for the Gavendas. Id.
In its analysis, the Texas Supreme Court noted the general rule that division
orders are binding until revoked and that they bind underpaid royalty owners. Id.
(citing Middleton, 613 S.W.2d at 250; Chicago Corp. v. Wall, 293 S.W.2d 844, 847
(Tex. 1956)). The court further noted that one of the principles underlying this rule
is detrimental reliance. Id. at 691–92. As explained by the court:
In the typical case, purchasers and operators following division orders
pay out the correct total of proceeds owed, but err in the distribution,
overpaying some royalty owners and underpaying others. If underpaid
royalty owners’ suits against purchasers and operators were not
estopped, purchasers and operators would pay the amount of the
overpayment twice—once to the overpaid royalty owner under the
division order and again to the underpaid royalty owner through his
suit. They would have double liability for the amount of the
overpayment. Exposing purchasers and operators to double liability is
unfair, because they have relied upon the division order’s
representations and have not personally benefited from the errors.
Id. at 692 (citation omitted). The court further noted that generally, the underpaid
royalty owners have a remedy to recover from the overpaid royalty owners under
the theory of unjust enrichment. Id. (citing Allen v. Creighton, 131 S.W.2d 47, 50
(Tex. App.—Beaumont 1939, writ ref’d)).
The court in Gavenda recognized that when the operator prepares erroneous
division orders and retains the benefits, Texas courts have held that the division
orders were not binding. Id. (citing Stanolind Oil & Gas Co. v. Terrell, 183 S.W.2d
743 (Tex. App.—Galveston 1944, writ ref’d)). Based upon this principle, the court
determined that the Gavendas were not bound by the division orders that they
executed because Strata Energy prepared the division order, distributed the royalties,
and retained the seven-sixteenths royalty that should have been distributed to the
Gavendas. Id. at 692–93. Thus, Strata Energy profited at the Gavendas’ expense.

14
Id. at 693. The court determined that Strata Energy was liable to the Gavendas “for
whatever portion of their royalties it retained, although it is not liable to the
Gavendas for any of their royalties it paid out to various overriding or other royalty
owners.” Id.
Because Devon paid out all of the royalty proceeds attributable to the Bray
Interest pursuant to division orders, it contends that under Gavenda, it is not liable
to Smitherman and Bremer as unpaid payees. In this regard, Devon contends that it
was not unjustly enriched. Conversely, Perdido asserts that Gavenda does not
control the outcome in this case because Smitherman and Bremer did not sign the
division orders. Perdido contends that there is no justification for imposing a rule
that binds non-signatory royalty owners to erroneous division orders signed by
another party.
Devon’s reliance on Gavenda is understandable because unlike Strata
Energy, Devon was not unjustly enriched—it paid out the total amount of royalty
due for the Bray Interest, albeit to the wrong parties. However, the holding in
Gavenda does not squarely align with the facts in this appeal. The parties have not
cited any post-Gavenda authority from Texas for the situation here involving a non-
signatory to division orders suing an operator that paid out royalties to the wrong
royalty owner.
The Texas Supreme Court has addressed Gavenda on a few occasions since
its issuance. In Heritage Resources v. NationsBank, the court cited Gavenda for the
proposition that “[w]hen an operator prepares a division order that allocates
payments among the interest owners in a manner that differs from the lease
provisions and the operator retains the benefits, the division order is not binding.
939 S.W.2d 118, 123 (Tex. 1996) (citing Gavenda, 705 S.W.2d at 692). The court
noted that the basis for the ruling in Gavenda was unjust enrichment. Id.

15
 The court revisited Gavenda in HECI Exploration Co. v. Neel, where it cited
Gavenda for the proposition that a royalty owner has a cause action against the
lessee based on unjust enrichment when the lessee profited at the royalty owner’s
expense. 982 S.W.2d 881, 891 (Tex. 1998) (citing Gavenda, 705 S.W.2d at 693).
As noted by the court in Neel, “[u]njust enrichment was the basis for recovery in
Gavenda.” Id. The court stated that it held in Gavenda that “division orders were
not binding on a royalty owner when the lessee erroneously prepared them and then
retained for itself the royalty that should have been paid.” Id.
These cases reflect that under Gavenda, division orders are not binding to
preclude a claim against the lessee when the lessee retains a benefit from the
erroneous division orders and is therefore unjustly enriched. Thus, the holding in
Gavenda reflects an exception to the general rule that division orders are binding
until revoked.
Devon relies on Gavenda for a different proposition—that if the lessee has
paid out all out of the royalties due for a particular interest under division orders
executed by other royalty owners, the unpaid royalty owner has no claim against the
lessee because the lessee has not been unjustly enriched. Instead, Devon contends
that the unpaid royalty owner’s sole remedy is to pursue a claim for unjust
enrichment against the overpaid royalty owners.
The North Dakota Supreme Court addressed a fact scenario similar to the
circumstances in this case in Acoma Oil Corp. v. Wilson. 471 N.W.2d 476 (N.D.
1991). Acoma involved a dispute over the payment of a 6.5% royalty interest. Id.
at 478. Acoma and the Bassett Trust asserted that they were entitled to recover from
the operator, Universal, for underpaid royalties that had been incorrectly deducted
from their royalty payments for the 6.5% royalty interest. Id. at 478, 484. The 6.5%
royalty interest should have been deducted wholly from Wilson’s interest. Id. at
484. Thus, Wilson had been overpaid by Universal. Id. Universal responded that
16
it was not liable to Acoma and the Bassett Trust because it relied on division orders
executed by Wilson and Acoma, and that it had paid 100% of the proceeds owed and
therefore was not unjustly enriched. Id.
The North Dakota Supreme Court noted the different status of Acoma and the
Bassett Trust—Acoma had signed a division order, but the Bassett Trust had not.
Id. The court quoted extensively from Gavenda in its analysis. Id. at 484–85. Citing
Gavenda, the court held that Acoma was not entitled to recover underpayments from
Universal during a period when Universal paid Acoma pursuant to executed division
orders. Id. at 485. But with respect to the Bassett Trust, the court held that because
the Bassett Trust had not executed division orders, Universal could not rely on the
division orders executed by the other parties to absolve it from underpaying the
Bassett Trust. Id. at 486. Thus, the Bassett Trust could recover underpaid royalties
from Universal—it was not limited to pursing a claim for unjust enrichment from
Wilson, the overpaid royalty owner. Id.
The North Dakota Supreme Court revisited the Acoma holding in Maragos v.
Newfield Production Co. 900 N.W.2d 44, 47 (N.D. 2017). In Maragos, the court
described the holding in Acoma as follows:
In Acoma, two underpaid parties with royalty interests in a tract of land
sought payments of the underpaid royalties from the oil company. The
oil company argued it was not liable for the underpayment because it
had “paid out 100% of the proceeds” and “received no benefit and has
not been unjustly enriched.” We disagreed, but differentiated between
the two parties based upon whether the party had entered into a division
and transfer order with the oil company. We held that the party who
executed a division order with the oil company should not be able to
recover from the oil company because the oil company had
detrimentally relied upon the order and it would subject them to double
liability. As to the party who had not executed a division order, we
found the oil company’s reliance on the title opinion could not absolve
it of all liability as to the underpayments and that party could recover
the underpayments from the oil company.

17
Id. (citations omitted). The North Dakota Supreme Court held that the lower court
misapplied Acoma. The court held that “in situations where a signed division order
is not present, the underpaid party can seek payments from the oil company.” Id.
The North Dakota Supreme Court once again revisited Acoma and Gavenda
in Continental Resources, Inc. v. Armstrong. 965 N.W.2d 57, 66–67 (N.D. 2021).
The court noted that:
Our rule is that when an operator has relied to its detriment on a
division order signed by an underpaid royalty owner, the underpaid
owner is estopped from recovering the underpayments from the
operator and must seek recovery from the overpaid royalty owners.
“The basis for the recovery is unjust enrichment; the overpaid royalty
owner is not entitled to the royalties.”
Id. at 67 (citation omitted) (quoting Acoma, 471 N.W.2d at 486). The court then
noted that in Maragos, it had held that:
[W]hen an operator has not “detrimentally relied” on a division order,
there is no basis for estopping an underpaid party’s attempt to recover
from the operator. Thus, when the underpayments are not made
according to a signed division order, the underpaid party “can seek
payments from the oil company.”
Id. (citations omitted) (quoting Maragos, 900 N.W.2d at 47).
In Acoma, Maragos, and Armstrong, the North Dakota Supreme Court
analyzed the holding in Gavenda and applied it to facts that are present in this case—
royalty interest owners who are not signatories to division orders bringing suit
against the operator for unpaid royalties. The court determined that even though the
operator had paid out all of the revenue attributable to the royalty interest under
division orders, a nonpaid or underpaid non-signatory could bring suit against the
operator for unpaid royalties. It was of no consequence that the operator may have
been exposed to double liability in this situation because it had not relied to its

18
detriment on any actions taken by the non-signatory. See Armstrong, 965 N.W.2d
at 67; Maragos, 900 N.W.2d at 47; Acoma, 471 N.W.2d at 485–86.
As noted previously, Smitherman and Bremer are not subject to the Enerlex
judgment because they were not parties to it. Similarly, they were also not parties
to the division orders upon which Devon paid royalties to De Leon and the Watson
Group. The opinions from North Dakota with respect to the effect of Gavenda on
the situation before us are both instructive and persuasive. For the same reasons
expressed by the North Dakota Supreme Court, we conclude that the holding in
Gavenda does not preclude Smitherman’s and Bremer’s suit against Devon for
unpaid royalties. See Armstrong, 965 N.W.2d at 67; Maragos, 900 N.W.2d at 47;
Acoma, 471 N.W.2d at 485–86. Even though Devon was not unjustly enriched, it
could not have detrimentally relied on the actions of Smitherman and Bremer
because they did not sign the division orders. Accordingly, Gavenda does not
preclude Smitherman and Bremer from bringing suit against Devon for unpaid
royalties. We sustain Perdido’s first issue. However, this issue is not dispositive of
this appeal because we must address Devon’s other grounds for summary judgment.
II. Appellant’s Claim for Breach of Contract
In Perdido’s second issue, it asserts that the trial court erroneously granted
Devon’s motion for summary judgment on Smitherman’s and Bremer’s claims for
breach of contract. Perdido contends that Devon breached the “oil and gas leases by
failing to pay royalties.” This contention pertains to both Smitherman’s claim and
Bremer’s claim. Perdido additionally asserts that, with respect to Smitherman’s
claim, Devon breached a release agreement by failing to pay the remainder of
Smitherman’s portion of the Bray Interest.
A. Claim for Breach of Lease—“Change in Ownership” Clause
Appellant’s claim for breach of the 2006 oil and gas lease concerns the same
unpaid royalties as their statutory claim for unpaid royalties covered in the previous
19
section. In many respects, the claim for breach of the lease mirrors the statutory
claim. However, there is a provision in the lease that Devon contends precludes
Smitherman’s and Bremer’s claims for breach of the lease.
The section of the lease upon which Devon relies provides as follows:
The rights of either party hereunder may be assigned in whole or in part
and the provisions hereof shall extend to their heirs, successors[,]
and assigns; but no change or division in ownership of the land,
shut-in royalties or royalties, however accomplished, shall operate to
enlarge the obligations or diminish the rights of Lessee; and no change
or division in such ownership shall be binding on Lessee until thirty (30)
days after Lessee shall have been furnished by registered U.S. Mail at
Lessee’s principal place of business with a certified copy of recorded
instrument or instruments evidencing same.
Devon contends that this provision absolves it from liability to Smitherman and
Bremer under the lease because it had paid all royalties due them to the Watson
Group prior to Perdido notifying Devon of Smitherman’s and Bremer’s claim.
We addressed a similar lease provision in Jones v. Clem. 2012 WL 1069168,
at *3. We referred to it as a “change in ownership” clause, and we noted that it
“relieve[s] a lessee from liability for the mispayment of royalty or delay rentals,
when the mispayment is caused by a change in ownership and no notice is given to
the lessee of such change” and that such clauses “have been upheld and enforced.”
Id. (citing Cassity v. Smith, 193 S.W.2d 991 (Tex. App.—Texarkana 1946, writ
ref’d)).
Here, the mispayment of the royalties due Smitherman and Bremer to the
Watson Group did not occur as a result of a change in ownership from the Watson
Group to Smitherman and Bremer—the Watson Group was never entitled to receive
the royalties due Smitherman and Bremer. Furthermore, Smitherman and Bremer
did not receive their interests as a result of an assignment from the Watson Group.

20
Accordingly, this portion of the change in ownership clause does not preclude
Smitherman’s and Bremer’s claim to royalties under the lease.
B. Release Agreement
On behalf of Smitherman, Perdido asserts that the trial court erred in granting
Devon’s motion for summary judgment on Smitherman’s claim for breach of
contract pertaining to a “release agreement” that he executed with Devon. 6 In
general terms, the release agreement provided for a payment of $50,000 from Devon
to Smitherman. However, the parties disagree on the effect of the agreement.
Devon contends that the $50,000 payment satisfied its entire obligation for
royalties on past production owed to Smitherman and barred him from bringing any
claims for past due royalties. Thus, Devon contends that the release agreement only
operates to reserve Smitherman’s right to royalties for future production because
Smitherman released all his claims for royalties for past production.
Perdido asserts that the release agreement did not release Smitherman’s
claims for royalties for past production. Perdido interprets the $50,000 payment as
merely a credit toward the entire amount of royalties for past production owed to
Smitherman.
As with any contract, our task is to “ascertain the true intentions of the parties
as expressed in the writing itself.” Murphy Expl. & Prod. Co.-USA v. Adams, 560
S.W.3d 105, 108 (Tex. 2018) (quoting Italian Cowboy Partners, Ltd. v. Prudential
Ins. Co. of Am., 341 S.W.3d 323, 333 (Tex. 2011)). This analysis begins with the
contract’s express language. Id. We construe the instruments as a whole, giving the
language its plain, ordinary, and generally accepted meaning unless the context
indicates that the parties used terms in a technical or different sense. Id. To the

6
El Dorado Resources, LLC, is also a party to the release agreement. Because El Dorado is not a
party to this appeal, we do not address the release agreement with respect to El Dorado.
21
extent possible, we strive to harmonize and give effect to all the contract provisions
so that none will be rendered meaningless. Id.
Neither party contends that the language of the release agreement is
ambiguous, nor do we find it to be ambiguous. When a contract can be given a
definite and certain meaning, it is not ambiguous even though the parties advance
competing constructions. URI, Inc. v. Kleberg Cnty., 543 S.W.3d 755, 764–65 (Tex.
2018). Unambiguous contracts must be enforced as written without considering
extrinsic evidence bearing on the parties’ subjective intent. Id. In keeping with our
commitment to freedom of contract, we will not rewrite it to add to or subtract from
its language or to interpolate constraints not found in the unambiguous language. Id.
The release agreement begins with several recitals. The release agreement
contains the following provision concerning its recitals: “6. The Parties
acknowledge and agree that the clauses in the preceding ‘Recitals’ section are true
and correct, and are incorporated herein as material parts to this Release.” The
recitals provide that Smitherman claimed an ownership interest in the subject wells
and that he had not been paid royalties for his claimed ownership interest. The
recitals further provide that Smitherman had demanded payment and an accounting,
and that Devon was investigating his demand. The recitals also provided that
“Smitherman is in the process of obtaining judicial confirmation of his ownership in
the Disputed Interest.” The recitals concluded with the following provision:
WHEREAS, pending resolution of the foregoing title issues and
receipt of the Order, Devon has agreed as an accommodation to
Smitherman to tender to Smitherman a payment relating to the Demand
as detailed herein in exchange for a release and further subject to the
terms and conditions of set forth herein.

22
 The next section of the release agreement was under the heading of
“Agreement.” The first paragraph of this section provides as follows:
1. Upon receipt of this Release fully executed by all
Parties, Devon will pay Smitherman a payment of fifty thousand
dollars ($50,000) (the “Payment”). The payment will be
tendered as a check made payable to “Leon C. Smitherman, Jr.”
in his individual capacity only. The Payment will be applied as
a credit towards any amounts due and owing Smitherman from
Devon, if any, for any ownership he is determined to have in the
Disputed Interest pursuant to the Order, within any applicable
statutes of limitations, assuming that an applicable statute of
limitations applies to the Disputed Interest. Devon reserves the
right to make any adjustments to or ask for return of the Payment
(either directly or through an appropriate judicial proceeding) in
the event that Smitherman is determined not to own the Disputed
Interest to which the Payment relates.
The next section of the release agreement is entitled “Release,” and it consists
of three parts. Subsection 2.A. provides that in exchange for the payment of the
$50,000 to Smitherman, he and those claiming through him “hereby fully and
forever release, discharge, acquit, settle, and hold Devon . . . harmless from any and
all Claims.” Subsection 2.B. defines “Claim” and “Claims,” by providing a very
broad definition of the two terms. Subsection 2.C. then limits that definition: “In
this Release, ‘Claim’ and ‘Claims’ does not include, and Smitherman is not
releasing, the right to payment of any principal royalty due on production from the
portion of the Disputed Interest that Smitherman is determined to own pursuant to
the Order.” Subsection 2.C. further provides that “the release granted herein is
conditional upon Devon . . . making payment to Smitherman of all remaining sums
due and owing to Smitherman (less the Payment) by virtue of the Order (such sum
being the “Balance Due”) within thirty (30) days following delivery of the Order to
Devon.”

23
 Under the terms of the release agreement, Devon’s payment of $50,000 to
Smitherman did not satisfy its obligation to him for royalties for past production.
We first note that the release agreement makes no distinction between past
production and future production and no reference to either past or future production.
Contrary to Devon’s position, the “carve-out” provision of Subsection 2.C. is not
limited to royalties for future production because the provision does not reference
future production. URI, Inc., 543 S.W.3d at 769–70 (Courts do not rewrite contracts
to add terms not originally supplied by the parties.). In the absence of an express
limitation in Subsection 2.C. to future production, its reference to “royalty due on
production” includes both past and future production. Thus, under Subsection 2.C.,
Smitherman did not release his right to payment for royalties due on any production,
including past production.
Other portions of the release agreement indicate that Smitherman did not
release his claim for royalties for past production based on the payment of $50,000.
The “agreement” provision quoted above specifies that the $50,000 payment “will
be applied as a credit towards any amounts due and owing Smitherman.” This
provision, along with a recital, contemplates that a determination of Smitherman’s
claim for royalties was in the process of being made. The agreement paragraph
further specifies that Devon retained the right to seek a return of the $50,000
payment from Smitherman in the event it was later determined that Smitherman did
not own the disputed interest and was therefore not entitled to any royalties. This
right of Devon to seek reimbursement indicates that the $50,000 payment was not a
final settlement of Smitherman’s claim for royalties for past production.
Devon poses the following question in its brief: “what claims were being
released under the Release Agreement if not royalties for past production?” The
answer to this question is not easy to articulate. With respect to the purpose of the
$50,000 payment, a recital in the release agreement specifies the purpose of the
24
payment—“an accommodation to Smitherman” in the form of an advance as partial
payment for the sums, if any, that Devon might later be determined to owe him for
royalties. The release agreement contemplates future events in two respects: (1) a
determination of Smitherman’s entitlement to royalties and (2) a future payment by
Devon of the remaining amount of royalties that Smitherman was entitled to receive.
Upon the occurrence of those two events, Smitherman’s claim for royalties would
be released under the terms of the release agreement. Additionally, the release
agreement also releases extra-contractual claims that Smitherman might possesses
against Devon.
In summary, the release agreement did not release Smitherman’s claim for
royalties for past production. To the extent that the trial court determined that it did,
it erred.
Because neither the terms of the oil and gas lease nor the terms of the release
agreement preclude Smitherman’s and Bremer’s claims for unpaid royalties, we
sustain Perdido’s second issue.
III. Limitations
Perdido’s third issue concerns Devon’s affirmative defense of limitations.
Perdido asserts that the trial court erred in calculating the date of accrual for the
applicable limitations period. Perdido also asserts that it raised a fact question on its
equitable defense to Devon’s claim of limitations. Additionally, Perdido contends
that Devon acknowledged its indebtedness to Bremer and that as a result, Bremer’s
claim is not subject to Devon’s limitation defense.
Perdido filed the underlying suit on behalf of Smitherman and Bremer on
October 3, 2017. Devon filed a motion for partial summary judgment asserting that
all claims for the nonpayment of royalties that accrued prior to October 3, 2013,
were barred based on the applicable four-year statute of limitations. The trial court
granted Devon’s motion for partial summary judgment by determining that
25
Smitherman’s and Bremer’s claims for the nonpayment of royalties accruing prior
to October 3, 2013, were barred by limitations. 7
“A defendant moving for summary judgment on the affirmative defense of
limitations has the burden to conclusively establish that defense.” Draughon v.
Johnson, 631 S.W.3d 81, 88 (Tex. 2021) (quoting Exxon Mobil Corp. v. Rincones,
520 S.W.3d 572, 593 (Tex. 2017)). “[T]he defendant has the burden regarding any
issues raised that affect which days count toward the running of limitations—such
as accrual, the discovery rule, and tolling.” Id. “[I]f the defendant carries that burden
and conclusively establishes its defense, the plaintiff can avoid summary judgment
by raising a genuine issue of material fact on any equitable defense that its suit
should not be barred even though the limitations period has run—such as fraudulent
concealment, estoppel, or diligent service.” Id. at 89.
A. Accrual of Limitations
The parties agree that the statute of limitations for unpaid royalties, whether
couched as a claim under the applicable statutes or a claim for breach of contract, is
four years. See Lyle v. Jane Guinn Revocable Tr., 365 S.W.3d 341, 354–55 (Tex.
App.—Houston [1st Dist.] 2010, pet denied); Headington Oil Co., L.P. v. White, 287
S.W.3d 204, 214 (Tex. App.—Houston [14th Dist.] 2009, no pet.); Koch Oil Co. v.
Wilber, 895 S.W.2d 854, 864 (Tex. App.— Beaumont 1995, writ denied);
Harrison v. Bass Enters. Prod. Co., 888 S.W.2d 532, 537 (Tex. App.—Corpus
Christi 1994, no writ); Dvorken v. Lone Star Indus. Inc., 740 S.W.2d 565, 566 (Tex.
App.—Fort Worth 1987, no writ). However, the parties disagree on when
Smitherman’s and Bremer’s claims for unpaid royalties accrued. The question of
accrual is important for multiple reasons. As noted previously, the date of accrual

The trial court incorporated the partial summary judgment into its final judgment granting Devon’s
7

motion for summary judgment as to the entire case.
26
is an element of Devon’s limitations defense. Additionally, the date of accrual is
relevant to Perdido’s equitable defenses to Devon’s limitations defense.
Production from the subject lands began in 2008. Perdido asserts that the
claims for nonpayment of royalties for production dating back to 2008 did not accrue
until March 6, 2013, because until that date, Devon held in suspense all sums that
should have been paid to Smitherman and Bremer. Thus, Perdido asserts that the
applicable limitations period did not expire on production occurring prior to
March 6, 2013, until March 6, 2017. 8 Conversely, Devon contends that the claim
for nonpayment of royalties accrued on a recurring, monthly basis.
“As a general matter, ‘a cause of action accrues and the statute of limitations
begins to run when facts come into existence that authorize a party to seek a judicial
remedy.’” Archer v. Tregellas, 566 S.W.3d 281, 288 (Tex. 2018) (quoting Knott,
128 S.W.3d at 221). This means that “a cause of action accrues ‘when a wrongful
act causes some legal injury, even if the fact of injury is not discovered until later,
and even if all resulting damages have not yet occurred.’” Id. (quoting S.V. v. R.V.,
933 S.W.2d 1, 4 (Tex. 1996)). Ordinarily, the cause of action in a breach of contract
case accrues when the breach occurs. Moreno v. Sterling Drug, Inc., 787 S.W.2d
348, 351 (Tex. 1990).
In Lyle v. Jane Guinn Revocable Trust, the First Court of Appeals determined
that royalty payments under a lease are periodic payments due during the course of
the contract and that a cause of action for such payments arises at the end of each
payment period. 365 S.W.3d at 355 (citing Intermedics, Inc. v. Grady, 683 S.W.2d
842, 845 (Tex. App.— Houston [1st Dist.] 1984, writ ref’d n.r.e.)). Thus, because
the lease at issue in Lyle contemplated a monthly accounting and payment of
royalties, limitations for the nonpayment of royalties accrued on a monthly basis,

8
As set out below, Perdido asserts that Smitherman and Bremer had grounds for extending the
period for filing suit from March 6, 2017, until the date suit was filed (October 3, 2017).
27
and limitations barred the recovery of royalty payments due more than four years
prior to the filing of suit. Id. The Corpus Christi–Edinburg Court of Appeals reached
the same result in Harrison v. Bass Enterprises Production Co., holding that a claim
for unpaid royalties accrued on a monthly basis “as oil and gas are produced and the
agreed royalty is not paid” based on the lease at issue. 888 S.W.2d at 537.
Here, the lease contemplates the payment of royalties on a monthly basis. The
pay records indicate that Devon paid royalties on a monthly basis. Additionally, the
applicable statute contemplates the payment of royalties based on the terms of the
lease. NAT. RES. § 91.402(a); see Leavitt v. Ballard Expl. Co., 540 S.W.3d 164, 171
(Tex. App.—Houston [1st Dist.] 2017, no pet.). Thus, under Lyle and Harrison,
limitations accrued on Smitherman’s and Bremer’s claims for the nonpayment of
royalties on a monthly basis beginning in 2008.
Perdido seeks an exception to the preceding legal authority that dictates a
monthly accrual for the nonpayment of royalties by asserting that Devon’s act of
holding the funds attributable to the Bray Interest in suspense until March 6, 2013,
changed the date of accrual. However, Perdido does not cite any authority for this
proposition, and we have found none. The Fourteenth Court of Appeals considered
a similar contention in Headington Oil Co. v. White. 287 S.W.3d at 213–14. There,
the plaintiffs asserted that the period of limitations was tolled under a constructive
trust theory because the operator, Gary, held unpaid royalties in suspense. Id. The
court rejected the contention of a constructive trust and held that limitations applied
to prohibit a claim for the nonpayment of royalties accruing more than four years
prior to filing suit against Gary. Id. at 214.
The same rationale applies to this case. Smitherman and Bremer were entitled
to royalties on a monthly basis beginning in 2008 when production started on the
subject properties. The fact that Devon held their royalties in suspense did not alter
their ability to bring suit against Devon for the nonpayment of royalties.
28
Accordingly, Perdido is incorrect in its contention that Smitherman’s and Bremer’s
claims for nonpayment of royalties for prior production did not accrue until March
6, 2013. Instead, Smitherman’s and Bremer’s claims for the nonpayment of royalties
accrued on a monthly basis beginning in 2008. Thus, Devon carried its burden to
conclusively establish the date of accrual. See Draughon, 631 S.W.3d at 88–89.
B. Claims for production occurring after October 2013
Because Smitherman’s and Bremer’s claims for nonpayment of royalties
accrued on a monthly basis, and because Perdido filed suit on their behalf in October
2017, their claims for royalties for production occurring after October 2013 were not
barred by limitations.
C. Estoppel to claim limitations for production occurring prior to
October 2013
Perdido asserts that Devon is estopped from asserting limitations. It contends
that Devon induced Perdido, Smitherman, and Bremer to delay filing suit until after
limitations expired. “[A] plaintiff may invoke equitable estoppel as an affirmative
defense in avoidance of a defendant’s limitations defense.” Rincones, 520 S.W.3d
at 593. Thus, Perdido had the burden to raise a fact issue on each element of its
affirmative defense in avoidance of limitations. See Draughon, 631 S.W.3d at 88–
89; Rincones, 520 S.W.3d at 593.
The elements of Perdido’s estoppel defense are: (1) Devon made a false
representation or concealed material facts; (2) with actual or constructive knowledge
of those facts; (3) with the intent that Smitherman, Bremer, and Perdido would act
on Devon’s representation; (4) to Smitherman, Bremer, and Perdido, who had no
means of knowledge of the facts; and (5) Smitherman, Bremer, and Perdido
detrimentally relied on the representations. See Rincones, 520 S.W.3d at 593–94
(citing Johnson & Higgins of Tex., Inc. v. Kenneco Energy, Inc., 962 S.W.2d
507, 515–16 (Tex. 1998)). Perdido generally contends that Devon made

29
misrepresentations to it, Smitherman, and Bremer that Devon was going to pay
Smitherman’s and Bremer’s claims for unpaid royalties and that Devon did so to
cause Perdido, Smitherman, and Bremer to delay filing suit until after limitations
had expired.
1. Claims for which limitations had already expired prior to Perdido
contacting Devon
Even if we accept Perdido’s contention of a misrepresentation as correct, it
must still show detrimental reliance that caused it to delay timely filing suit. See id.
Perdido did not contact Devon on behalf of Smitherman until November 11, 2016,
and Perdido did not contact Devon on behalf of Bremer until February 16, 2017.
Thus, Devon’s alleged misrepresentations did not occur before these dates. With
respect to Smitherman, the applicable limitations period had expired for production
occurring prior to November 2012 when Perdido contacted Devon on behalf of
Smitherman. With respect to Bremer, the applicable limitations period had expired
for production occurring prior to February 2013 when Perdido contacted Devon on
behalf of Bremer.
The Corpus Christi–Edinburg Court of Appeals dealt with an analogous
situation in Conway v. Durell. No. 13-10-00614-CV, 2012 WL 3043100, at *6 (Tex.
App.—Corpus Christi–Edinburg July 26, 2012, no pet.) (mem. op.). It held that a
plaintiff cannot show harm or prejudice, and thus cannot establish estoppel, for
claims for which the applicable limitations had already expired at the time of the
alleged misrepresentation. Id. We conclude that this interpretation is correct.
Accordingly, Perdido has not raised a fact issue on its estoppel claim for
Smitherman’s claim for royalties occurring from production prior to November 2012
and for Bremer’s claim for royalties occurring prior to February 2013. See id.

30
 2. Claims that could have been subject to estoppel
Our next focus with respect to Perdido’s estoppel claim is on the period of
time for production between November 2012 (for Smitherman) / February 2013 (for
Bremer) and October 2013 (four years prior to Perdido filing suit). 9 Because Perdido
treats Smitherman’s and Bremer’s claim separately, we consider them separately as
well.
a. Smitherman’s claims for royalties from production from
November 2012 until October 2013
With respect to Smitherman’s claim, Perdido contends that Devon is estopped
to assert limitations because of the December 2016 release agreement. Perdido’s
contention in this regard is premised on its assertion that limitations did not accrue
for unpaid royalties until March 6, 2013 (the date that Devon paid all royalties held
in suspense to the Watson Group). However, we have rejected Perdido’s contention
of a delayed accrual. As noted previously, limitations for the nonpayment of
royalties accrued on a month-to-month basis.
The release agreement did not estopp Devon from asserting limitations. The
“Agreement” portion of the release agreement references that the $50,000
accommodation payment was being made for Devon’s ultimate liability to
Smitherman “within the applicable statutes of limitations.” A later portion of the
release agreement provides that Devon “hereby expressly reserve[s] and preserve[s],
and do[es] not waive, any and all claims and defenses available to [it].” Accordingly,
Devon was not estopped by the release agreement to assert limitations for
Smitherman’s claim for unpaid royalties.

9
As noted previously, October 3, 2013, is the date used by the trial court in granting Devon’s motion
for partial summary judgment.
31
 b. Bremer’s claim for royalties on production from February
2013 until October 2013
As set out below, we conclude that Devon acknowledged its indebtedness to
Bremer. Accordingly, we do not address Perdido’s estoppel defense as it pertains to
Bremer’s claim.
c. Devon’s acknowledgment of its debt to Bremer for unpaid
royalties
On behalf of Bremer, Perdido asserts an additional ground as an alternative to
Devon’s limitations claim—that Devon acknowledged its indebtedness to Bremer.
“Although a debt is barred by limitations, limitations can be avoided if the party to
be charged acknowledges the debt in writing.” In re Estate of Curtis, 465 S.W.3d
357, 367 (Tex. App.—Texarkana 2015, pet. dism’d). Section 16.065 of the Texas
Civil Practice and Remedies Code provides as follows:
An acknowledgment of the justness of a claim that appears to be
barred by limitations is not admissible in evidence to defeat the law of
limitations if made after the time that the claim is due unless the
acknowledgment is in writing and is signed by the party to be charged.
TEX. CIV. PRAC. & REM. CODE ANN. § 16.065 (West 2015). An acknowledgement
of a debt under the statute creates a new obligation. Stine v. Stewart, 80 S.W.3d 586,
591 (Tex. 2002). “A suit on a debt is separate from a suit on a later written
acknowledgment of the debt, and the latter is not barred by limitations merely
because the former is.” DeRoeck v. DHM Ventures, LLC, 556 S.W.3d 831, 834
(Tex. 2018). The acknowledgment of a debt can come before or after suit on the
original debt is barred by limitations. Id. (citing Cain v. Bonner, 194 S.W. 1098,
1098 (Tex. 1917)).
To prevail on a claim for acknowledgment of a debt, the party asserting it
must show that the acknowledgment was: “(1) . . . in writing and signed by the party
to be charged; (2) contain an unequivocal acknowledgment of the justness or the

32
existence of the particular obligation; and (3) refer to the obligation and express a
willingness to honor that obligation.” Id. (citing Stine, 80 S.W.3d at 591). As noted
by the San Antonio Court of Appeals:
[I]n order for a written instrument to be sufficient to take a debt
otherwise barred out of the operation of the statute of limitations, it
must acknowledge the justness of the debt and express a willingness to
pay. Where the debt is clearly acknowledged, however, the promise to
pay is implied.
Bright & Co. v. Holbein Fam. Min. Tr., 995 S.W.2d 742, 745 (Tex. App.—San
Antonio 1999, pet. denied). “[T]he amount of the obligation the acknowledgment
describes must be ‘susceptible of ready ascertainment.’” Stine, 80 S.W.3d at 591–
92 (quoting Stefek v. Helvey, 601 S.W.2d 168, 171 (Tex. App.—Corpus Christi
1980, writ ref’d n.r.e.)). Whether a written instrument sufficiently acknowledges a
barred debt is a question of law. Bright & Co., 995 S.W.2d at 745.
The summary judgment evidence put forth by Devon and Perdido pertaining
to Bremer’s acknowledgment claim consists of Bremer’s demand letter, several
emails between the parties sent between March 2017 and May 2017, and a voided
check that Devon issued. Perdido asserts that these communications establish that
Devon unequivocally acknowledged its debt to Bremer and, thus, that the trial court
erred in granting Devon’s summary judgment motion on this contention and denying
Perdido’s motion. Conversely, Devon contends that the summary judgment
evidence merely establishes that the parties were engaged in an ongoing negotiation
to determine what, if anything, Devon owed to Bremer.
i. Devon’s emails were signed
We begin our analysis by determining whether Devon signed the emails that
are part of the summary judgment evidence. The emails that Bremer contends show
that Devon acknowledged the debt contained various signature blocks from

33
employees of Devon. The signature block for emails on March 2, 2017, and May 2,
2017, were as follows:
Cherish
Cherish K. Ralls
Counsel
Devon Energy Center
The signature blocks for emails on April 10 and May 3, 2017, were as follows:
Cherish K. Ralls
Counsel
Devon Energy Center
The signature block for an email on April 11, 2017, was as follows:
Kristin Milster
Division Order Analyst
Devon Energy Production Company, LP (DEPCO)
And an email on April 12, 2017, was simply signed: “Cherish.”
Generally, a record or signature cannot be denied legal effect “solely because
it is in electronic form.” TEX. BUS. & COM. CODE ANN. § 322.007(a) (West 2023).
If a law requires a record or signature to be in writing, an electronic version of either
will satisfy that requirement. See id. § 322.007(c)–(d). In this regard, the Texas
Uniform Electronic Transactions Act (TUETA) defines an “electronic signature” as
“an electronic sound, symbol, or process attached to or logically associated with a
record and executed or adopted by a person with the intent to sign the record.” Id.
§ 322.002(8).
There is a split of authority concerning whether a signature block on an email
constitutes a signature. In Cunningham v. Zurich American Insurance Co., the Fort
Worth Court of Appeals held that a signature block at the end of an email was not a
signature. 352 S.W.3d 519, 529–30 (Tex. App.—Fort Worth 2011, pet. denied).
The court reasoned that there was nothing to show that the signature block was typed

34
by the sender “and not generated automatically by her email client.” Id. at 530. The
court further noted that there was no indication that the sender intended for her
signature block to be her signature. Id.
In Williamson v. Bank of New York Mellon, the court applying Texas law held
that the signature block of an email was sufficient to qualify as a signature under the
Texas Business and Commerce Code. 947 F. Supp. 2d 704, 709–10 (N.D. Tex.
2013). The court concluded that a manually typed name on an email constitutes an
electronic signature because it “represent[s] electronic symbols attached to a record
and executed with the intent to sign the record as contemplated by TUETA.” Id. at
709. The court further determined that an automatically attached signature block to
an email also constitutes an electronic signature. Id. at 710–11. The court reasoned
that the signature block is created by the email user rather than his or her email
service, and that the email user intended for it to serve as his or her signature by
creating it and setting up his email service to automatically attach it to his or her
emails. Id. at 710. The court opined:
[A]s a result of the “continued expansion” of email communication, a
signature block at the bottom of an email has come to represent what a
handwritten signature once represented: a means of identifying the
sender, signaling that he or she adopts or stands behind the contents of
the communication, and a method of ensuring that the communication
is authentic.
Id. at 711. In reaching this conclusion, the federal court cited Cunningham and noted
its disagreement with its holding.
The First Court of Appeals has gone a step further by holding that a name or
email address in the “from” field of an email may be construed as an electronic
signature for TUETA purposes. Khoury v. Tomlinson, 518 S.W.3d 568, 576 (Tex.
App.—Houston [1st Dist.] 2017, no pet.). The court noted that a name or email
address in the “from” field “is a symbol logically associated with the email.” Id.

35
(citing BUS. & COM. § 322.002(8)). The court also noted that “[t]he ‘from’ field
functions to identify the sender of the email and authenticate the email as his act.”
Id. at 577. The court in Khoury also cited Cunningham and noted its disagreement
with its holding. Id. at 577–78. Additionally, the court in Khoury noted its approval
of the holding in Williamson. Id. at 578.
The reasoning utilized by the court in Williamson is persuasive. As noted by
the court, signature blocks are generated by the email user and not the user’s email
client or service. Williamson, 947 F. Supp. 2d at 710. As noted by the court, a
signature block at the end of an email has come to represent what a handwritten
signature on a letter once represented. Id. at 711. Accordingly, we conclude that
either a typed name or a signature block at the end of an email is sufficient to
constitute a signature. See id. Because each of the emails proffered as summary
judgment evidence contains either a typed name or a signature block from an
employee of Devon, each contains a sufficient signature under Section 16.065 of the
Civil Practice and Remedies Code.
ii. The text of the emails
Perdido’s attorney, Kyle K. Wittenbraker, wrote a demand letter to Devon on
behalf of Bremer dated February 16, 2017. On behalf of Devon, its counsel, Cherish
K. Ralls, wrote an email to Wittenbraker on March 2, 2017, in response to the
demand letter. Ralls’s response read:
We are in receipt of the 91.404 request for Mr. Bremer. Devon has
reviewed through [sic] the records and while there are few [sic]
discrepancies in your correspondence that I will address later, we do
feel that we can go ahead and get the funds paid to Mr. Bremer due and
owing through Jan 1, 2016 revenues. This all said, I would request an
additional 30 days for us to be able to correctly have the entries
manually adjusted. This would make check write [sic] for the payment
in mid April.

36
 Please let me know by Tuesday if this accommodation is acceptable to
Mr. Bremer?
Devon contends that this email does not constitute an unequivocal acknowledgment
because it noted discrepancies in Wittenbraker’s demand letter and because it stated
that Devon only had a “feeling” that funds would be paid. Devon further asserts that
it did not express a willingness or intent to pay Appellant because it was determining
what amounts may be owed.
On April 10, 2017, Ralls wrote an email to Wittenbraker that stated: “Attached
is a division order for Mr. Bremer to execute. The sooner that we get this signed the
sooner we can put him in pay for those past amounts. Contact Kristin or me with
questions.” Devon contends that this email did not acknowledge the alleged debt to
Bremer and it provided no ascertainable amount.
Wittenbraker replied on April 11, 2017, in an email stating that Bremer
executed the division order and had sent it back by overnight mail. Wittenbraker
also inquired: “Can you please provide an estimate as to the amount he will be paid?”
On behalf of Devon, Kristin Milster replied by email on April 11, 2017 as follows:
“The approximate amount that will be disbursed to Mr. Bremer is $268,500 pending
final adjustments.” Devon contends that this email did not constitute an unequivocal
acknowledgement of the debt and that, because the email says “pending final
adjustments,” the amount of debt owed is not readily ascertainable. In this regard,
Devon points to deposition testimony wherein its representative testified that at the
time the email was sent, it was still determining what amount, if any, Bremer would
receive.
On April 12, 2017, Ralls again emailed Wittenbraker, stating as follows:
We have received the division order from Mr. Bremer. Given the
amount involved with this payment and that the declaration of heirship
for Mr. Bremer’s interest is close to be [sic] decided, we will plan to

37
 send Mr. Bremer’s payment as soon as the order for heirship is entered
later this month.
Devon asserts that this email does not make an unequivocal acknowledgement of a
debt owed to Bremer because it was conditioned upon the result of the heirship
proceeding.
On May 1, 2017, the County Court at Law of Ector County entered its
judgment declaring heirship wherein it determined that Bremer owned 1/4 of the
Bray Interest. Following the entry of the judgment declaring heirship, Wittenbraker
emailed Ralls and Milster on May 2, 2017, asking them when Bremer could expect
to be paid. Ralls emailed Wittenbraker that day in response, stating: “A check was
cut payable to Mr. Bremer but it was placed on hold waiting on the pending order
and hearing. Now that we have received the order on heirship, we should be able to
release this payment to him this week.”10 Devon asserts that its act of not sending
the check indicates that it did not unequivocally acknowledge its indebtedness to
Bremer.
On May 3, 2017, Ralls again emailed Wittenbraker stating as follows:
Attached is an acknowledge and release that I am including with Mr.
Bremer’s check. I expect to be able to send it out tomorrow. We would
request that he sign the attached document and return it as soon as he
can. Please let me know if you have any concerns with the
acknowledge and release language in the document.
Devon asserts that this email conditioned payment on Bremer’s execution of the
release that accompanied the email. Wittenbraker replied as follows to the email:
I am adapting the earlier release we used when [Smitherman] got his
partial payment for your review. Once we approve the form of release
for Mr. Bremer, I am sure Mr. Smitherman will be more than happy to

10
The summary judgment evidence contains a voided check entry indicating that Devon issued a
check on April 15, 2017, for $268,521.17, but that it subsequently voided the check.
38
 execute a similar release for the balance of the funds he is owed. Do
you know when that check (Mr. Smitherman) might be issued?
On May 4, 2017, Ralls again emailed Wittenbraker, stating as follows:
My apologies but on the release I sent yesterday, we miscalculated the
amount actually due Mr. Bremer within the statute of limitations period
for 4 years from the date of notice to the date of production. I hope to
have an updated number for you on this and also let you know what the
number for Mr. Smitherman, Jr. will be.
The May 4, 2017, email was the first time in the correspondence between Devon and
Wittenbraker wherein Devon referred to limitations in its calculation of unpaid
royalties it owed to Bremer. A Devon representative testified by deposition that at
some point Devon received an email from one of the Watson Group’s attorneys. In
that email, Devon learned that it had a statute of limitations defense with respect to
Bremer’s claim for unpaid royalties. Devon then decided to assert limitations.
Devon takes a divide-and-conquer approach by challenging each of its emails
separately to assert that none of them, standing alone, is sufficient to constitute the
acknowledgment of its indebtedness to Bremer. However, the emails must be
construed together along with the emails from Wittenbraker to ascertain the nature
of the ongoing discussion between Devon and Bremer. A case that is instructive on
this point is Hutchings v. Bayer, 297 S.W.2d 375 (Tex. App.—Dallas 1956, writ
ref’d n.r.e.). In Hutchings, the court considered two letters together in determining
that the defendant acknowledged a readily ascertainable debt. 297 S.W.2d at 377–
78. The first letter in Hutchings stated that “[the plaintiff] has discussed with me the
matter of your indebtedness to him, the amount being in the neighborhood of
$20,000.” Id. at 377. In the second letter, the defendant stated that “[t]he latter
part of this week or next you will receive a payment. I have not denied my
obligation . . . .” Id. In concluding that these letters sufficiently acknowledged the

39
debt, the court stated that “these two letters are to be considered together, the subject
of discussion undoubtedly being defendant’s indebtedness.” Id. at 378.
Devon relies on its internal discussions to contend that it did not acknowledge
its indebtedness to Bremer. However, these discussions concerning Devon’s
hesitancy to pay Bremer were not revealed to Wittenbraker. Our focus is on Devon’s
intentions as expressed in the writings that were conveyed to Bremer, rather than
Devon’s subjective beliefs or its internal discussions. See Murphy Expl. & Prod.
Co.-USA, 560 S.W.3d at 108.
The context of the written communications between Devon and Wittenbraker
prior to May 4, 2017, indicate that Devon believed Bremer’s claim for unpaid
royalties was legitimate. The emails demonstrate a willingness to pay him after two
conditions were met—the entry of the judgment declaring heirship and his execution
of division orders. Both of these conditions were met prior to May 4, 2017. Thus,
Devon’s reliance on these conditions to assert that its acknowledgement of its
obligation to Bremer was equivocal is misplaced.
Bright & Co. v. Holbein Family Mineral Trust aids our analysis. In Bright,
the San Antonio Court of Appeals was tasked with determining whether Bright
acknowledged a debt to the Holbein Trust for unpaid royalties. 995 S.W.2d at 745–
46. In concluding that Bright acknowledged its indebtedness to the trust for unpaid
royalties, the court relied on a letter Bright sent the trust’s attorney and a fax Bright
sent to the trust. Id. The letter provided as follows:
To update you with our progress, this will advise that we have
conducted a search of the records of Jim Hogg County. We found no
record of any conveyance out of the Holbein family that would cause
their ½ (of 1/4) royalty to diminish. As a result, I have consulted with
a representative of the Major family (owner of the other ½ of the
royalty) for a possible explanation. In addition, we are searching our
records for other possible explanations. We are also accruing
information as to the exact month and year, (Mr. Holbein advised us it

40
 was 1987), that royalty payments ceased and further, the amount of
production/income that is involved. Please bear with us as we have
every intention of seeing that this matter is resolved. Please forward a
copy of this letter to Mr. Holbein with our appreciation for his patience.
Should you have any questions, please let me know.
Id. The fax contained production figures and showed a “net due Holbein” in a
specific dollar amount. Id. at 746. With respect to Bright’s letter, the court stated
as follows:
[Bright’s] letter acknowledged the justness of the debt and implied that
the Holbein family was entitled to the unpaid royalty payments. The
letter also stated that Bright had found nothing to indicate that the
Holbein’s interest had diminished. It further stated that Bright had
every intention of resolving the matter, which implies a willingness to
pay the debt.
Id. The court determined that Bright’s letter and fax amounted to an
acknowledgement of its debt to the Holbein trust for unpaid royalties. Id.
Here, Devon’s emails to Bremer from March 2, 2017, through May 3, 2017,
repeatedly assured Bremer that Devon would pay him for unpaid royalties without
any reference to limitations barring any portion of its obligation to Bremer. Devon
also told Bremer in these emails the approximate amount he would be paid. Devon
went so far as to send division orders to Bremer to execute and tell Wittenbraker that
it had already cut a check to Bremer. Thus, Devon went further than the defendant
in Bright in acknowledging the justness or existence of its obligation to Bremer for
unpaid royalties and its willingness to honor that obligation. See Stine, 80 S.W.3d
at 591; Bright & Co., 995 S.W.2d at 745–46. Therefore, the combined force of all
of Devon’s emails to Bremer from March to May 3, 2017, constitutes an
acknowledgement of its indebtedness to Bremer for unpaid royalties irrespective of
limitations. Therefore, we reverse the trial court’s grant of Devon’s motion for
summary judgment on the matter of its acknowledgment of its debt to Bremer and

41
render judgment in favor of Bremer to the effect that, from March to May of 2017,
Devon acknowledged its debt to Bremer.
D. Disposition
We sustain Perdido’s third issue with respect to Smitherman’s claim for
unpaid royalties for production occurring after October 2013 and Bremer’s claim for
unpaid royalties. We overrule Perdido’s third issue with respect to Smitherman’s
claim for unpaid royalties for production occurring before October 2013.
IV. Smitherman’s Alternative Claim for Fraudulent Inducement
Perdido’s fourth issue concerns its alternative claim that Devon fraudulently
induced Smitherman to enter into the release agreement. Specifically, Perdido
asserts that Devon fraudulently induced Smitherman to execute the release
agreement by representing to him that it would pay all amounts due and owing to
Smitherman for unpaid royalties (less the $50,000 payment to Smitherman). Perdido
asserts that Devon had no intention of paying Smitherman anything more than
$50,000 and that Devon’s action induced Smitherman to delay filing suit against
Devon.
“Texas law has long imposed a duty to abstain from inducing another to enter
into a contract through the use of fraudulent misrepresentation.” Anderson v.
Durant, 550 S.W.3d 605, 614 (Tex. 2018). The elements of fraudulent inducement
are: “(1) a material misrepresentation, (2) made with knowledge of its falsity or
asserted without knowledge of its truth, (3) made with the intention that it should be
acted on by the other party, (4) which the other party relied on, and (5) which caused
injury.” Id. In order for fraudulent inducement to exist, there must be a promise of
some future performance “made with a present intent not to perform.” Id. (citing
Formosa Plastics Corp. USA v. Presidio Eng’rs & Contractors, Inc., 960 S.W.2d
41, 47 (Tex. 1998) (op. on reh’g)).

42
 In many respects, Smitherman’s claim for fraudulent inducement mirrors its
claim of equitable estoppel that we addressed above in discussing Devon’s
limitations defense. As with Smitherman’s equitable estoppel claim, Smitherman’s
fraudulent inducement claim is premised on an accrual date of March 6, 2013, for
unpaid royalties for production occurring before that date. We have rejected
Perdido’s claim of a delayed accrual date by determining that limitations for unpaid
royalties accrued on a monthly basis as production occurred. We have also noted
that because Perdido did not contact Devon about Smitherman’s claim until
November 2016, Devon’s conduct could not have delayed the timely filing of suit
for production occurring prior to November 2012. That same principle is applicable
to Smitherman’s claim for fraudulent inducement. Accordingly, we direct our
attention to Smitherman’s claim for unpaid royalties for production occurring from
November 2012 to October 2013.
Smitherman’s fraudulent inducement claim suffers the same fate as his
equitable estoppel claim because it ignores the language in the release agreement
that any further payment to Smitherman would be adjusted “within any applicable
statute of limitations.” Thus, by its express terms, the release agreement
contemplated that Devon could assert any applicable limitations defense. In this
regard, there is a provision in the release agreement in bold text wherein each party
acknowledged that it had read the release and had consulted with legal counsel
regarding it. Therefore, we must assume that Smitherman knew that his recovery
for unpaid royalties may be limited by the applicable statute of limitations. This
provision of the release agreement to the effect that Devon preserved its limitations
defense precludes Smitherman’s claim for fraudulent inducement. We overrule
Perdido’s fourth issue.

43
 V. Devon’s Conditional Cross-Point
Devon presents a conditional cross-point wherein it asserts that the trial court
did not dispose of Devon’s cross-claim against the Watson Group for indemnity or
its counterclaim against Perdido and Smitherman. Devon based its cross-claim for
indemnity against the Watson Group based on the terms of the division orders.
Devon based its counterclaim against Perdido and Smitherman on the allegation that
they breached the release agreement by filing suit against Devon for unpaid royalties
for past production.11 Devon also sought to be reimbursed for the $50,000 that it
paid to Smitherman if it is determined that Smitherman does not own the disputed
interest to which the payment related. Devon’s cross-point is conditioned on a
reversal of the summary judgment granted in Devon’s favor.
Contrary to Devon’s suggestion, the trial court disposed of Devon’s cross-
claim and counterclaim because the trial court entered a final judgment that disposed
of all parties and all claims in the underlying case. See Patel v. Nations Renovations,
LLC, 661 S.W.3d 151, 154 (Tex. 2023) (“[C]ourts will deem a judgment without a
trial to be final ‘(1) [when the judgment] actually disposes of every pending claim
and party or (2) [when] it clearly and unequivocally states that it finally disposes of
all claims and parties, even if it does not actually do so.’” (alterations in original)
(quoting In re Guardianship of Jones, 629 S.W.3d 921, 924 (Tex. 2021))). Here,
the trial court entered a summary judgment order that concluded with the following
statement: “This order is final, appealable, and disposes all claims between all
parties.” See id. Thus, the trial court disposed of Devon’s cross-claim and
counterclaim.

We have determined that, as a matter of law, Perdido and Smitherman did not breach the release
11

agreement by filing suit against Devon for unpaid royalties from past production.
44
 Devon appears to be asserting that, in the event of a reversal, the case should
be remanded for the consideration of its cross-claim against the Watson Group and
its counterclaim against Perdido and Smitherman. As set forth herein, we are
remanding the following claims for trial: Smitherman’s claim for unpaid royalties
for production occurring after October 2013 and Bremer’s claim for unpaid royalties.
In doing so, we are not limiting the remand by special instructions. See Hudson v.
Wakefield, 711 S.W.2d 628, 630–31 (Tex. 1986); Simulis, L.L.C. v. Gen. Elec. Cap.
Corp., 392 S.W.3d 729, 734 (Tex. App.—Houston [14th Dist.] 2011, pet. denied)
(citing Hudson, 711 S.W.2d at 630). As noted in Simulis: “Generally, when an
appellate court reverses and remands a case for further proceedings, and the mandate
is not limited by special instructions, the effect is to remand the case to the lower
court on all issues of fact, and the case is reopened in its entirety.” 392 S.W.3d at
734. This principle is particularly applicable in the context of an appeal involving a
summary judgment because the appellate court is limited in its consideration of the
relevant issues and facts. See Hudson, 711 S.W.2d at 630–31; Eagle Supply & Mfg.
L.P. v. Landmark Am. Ins. Co., 630 S.W.3d 342, 353 (Tex. App.—Eastland 2021,
pet. denied). Accordingly, Devon will be permitted to pursue its cross-claim and
counterclaim to the extent that they are not inconsistent with this opinion.12
This Court’s Ruling
The trial court’s summary judgment in favor of Devon on Smitherman’s claim
for unpaid royalties for production occurring after October 2013 and Bremer’s claim
for unpaid royalties is reversed, and this cause is remanded for further proceedings
consistent with this opinion. The remainder of the trial court’s summary judgment—

12
“Under the law-of-the-case doctrine, questions of law decided on appeal will govern the case
throughout its subsequent stages.” Eagle Supply & Mfg. L.P., 630 S.W.3d at 354 (citing Hudson, 711
S.W.2d at 630). Here, our interpretation of the Enterlex judgment, our interpretation of the Gavenda
holding, our interpretation of the release agreement, and our determination that Devon acknowledged its
indebtedness to Bremer are questions of law that we have decided in this appeal.

45
with the exception of its disposition of Devon’s cross-claim and counterclaim—is
affirmed.
