On Petition for Review from the
Court of Appeals for the Eleventh District of Texas
═══════════════════════════════════════
Argued October 6, 2022
JUSTICE YOUNG delivered the opinion of the Court.
Only in a legal text could the formula “one-half of one-eighth”
mean anything other than one-sixteenth. But in the law, “one-half of
one-eighth” sometimes equals one-half—in the context of reservations of
mineral interests. Likewise, the law sometimes calculates one-half of
1,000 to be 600, not 500—in the context of contracts for rabbits. Those
results may seem bizarre, unsatisfying, and literally fuzzy math. They
can also be inefficient; resolutely adhering to the rules of arithmetic
1
would more rapidly end litigation. The rules that courts must apply,
however, are not primarily those of arithmetic but of textual construction.
The rules of construction, in turn, reflect the principle that legal texts—
including private-law documents like contracts, deeds, and wills—still
bear the meaning that their words had when they were drafted, even if
the use of the same words today might generate a different meaning.
This case involves the first seeming oddity mentioned above: the
so-called “double-fraction” dilemma from antique mineral conveyances
in which the parties insisted on using two fractions. We must stretch
back nearly a century to determine the meaning of a 1924 deed’s mineral
reservation of “one-half of one-eighth.” This is not our first case involving
double fractions, and it is likely not our last. But building on our
precedents, and focused on our duty to faithfully interpret any legal text,
we anticipate at least substantially reducing the frequency of disputes
about double fractions. We conclude that an accurate construction of
the 1924 text requires us to accept that the equation “one-half of one-
eighth” equals one-half of the mineral estate. Even if this were not so,
nearly a century of the parties’ unbroken understandings and
representations would require us to recognize that allocation of present-
day ownership by applying the presumed-grant doctrine. We accordingly
reverse the judgment of the court of appeals and remand the case to the
trial court for further proceedings.
I
In 1924, George H. Mulkey and Frances E. Mulkey conveyed their
ranch and the underlying minerals to G. R. White and G. W. Tom (who
had a general partnership called “White and Tom”) with the following
2
reservation:
It is understood and agreed that one-half of one-eighth of
all minerals and mineral rights in said land are reserved
in grantors, Geo. H. Mulkey and Frances E. Mulkey, and
are not conveyed herein.
After the deed’s execution, both parties, their assignees, and
various third parties engaged in numerous transactions and filings
reflecting that each side of the original conveyance had an equal 1/2
interest in the minerals. This included further conveyances, leases,
ratifications, division orders, contracts, probate inventories, stipulations,
and various other recorded documents. In 1946, however, Ethel Stuckert,
the Mulkeys’ daughter, wrote the following to her brother in a letter:
After several weeks of consultations . . . between Mr. G. R.
White, George [F. Mulkey] and [Young] J. [Mulkey], a
contract was entered into whereby Mama, and Papa’s heirs,
will receive one half of the mineral rights on the old ranch
land.
The record does not otherwise confirm that such a “contract” was in fact
executed. If it was, it has been lost to time; at least, the record before
us does not include it. Nor does the record explain why the parties would
have wanted to enter into such a contract, whether any consideration
was paid, or whether (if in fact executed) it was genuinely a “contract”
at all rather than a clarification.
Nonetheless, both before and after that letter, one important
feature remained constant. Specifically, for nearly ninety years after
the original deed’s execution, the parties (including new owners who
received various interests) continued without exception to engage in
transactions and to make representations about their ownership interests
that were consistent with the understanding that each original side had
3
always had a 1/2 interest in the minerals.
The present litigation represents the breakdown of that mutual
understanding of equal ownership. The two sides are called either “the
White parties” (those whose interests derive from White and Tom, the
grantees, and who are respondents in this Court) or “the Mulkey parties”
(those whose interests derive from the grantors, and who are petitioners
here). In 2013, the White parties brought this trespass-to-try-title action
after Endeavor Energy began to pay royalties from its drilling operation
to both parties in equal shares. At stake is at least $44 million in
accumulated disputed royalties.
The ownership of those (and presumably future) royalties turns
on which side correctly interprets the deed’s mineral reservation of “one-
half of one-eighth.” The White parties assert that the double fractions
are merely an elementary arithmetic formula with no additional
meaning, so that only a 1/16 interest was ever reserved. The Mulkey
parties contend that the double fraction reflects a term of art common
at the time the deed was drafted and that the use of this term of art
reserved 1/2 of the mineral interest. Alternatively, the Mulkey parties
assert that even if the deed had only reserved a 1/16 interest, they gained
title to the remaining 7/16 by operation of the presumed-grant doctrine
at some point after 1924 but long before the $44 million accrued.
After both parties filed various competing summary-judgment
motions, the trial court entered an order granting the White parties’
motion for partial summary judgment on the construction of the 1924
deed. The order declared that the deed’s reservation of “one-half of one-
eighth of all minerals and mineral rights” unambiguously reserved only
4
a 1/16 interest in the mineral estate. The trial court then denied the
Mulkey parties’ alternative motion for partial summary judgment, which
asked the trial court to declare that they owned title to 1/2 of the mineral
interest by virtue of the presumed-grant doctrine or various other defenses.
The court granted the White parties’ accompanying no-evidence motion
for summary judgment with respect to the Mulkey parties’ “affirmative
claims and/or defenses based upon theories of adverse possession,
estoppel (both equitable and judicial), waiver, laches, estate misconception,
presumed grant, lost deed, fraud, and failure to mitigate damages.” All
other claims were severed, and two other appeals involving the 1924
deed have been abated pending our decision in this case.
The court of appeals affirmed. 647 S.W.3d 901, 913 (Tex. App.—
Eastland 2020). It held that the deed unambiguously conveyed 15/16 of
the mineral estate. Id. at 908. The court concluded that the estate-
misconception theory—the theory that the Mulkey parties press to justify
their counter-arithmetical reading—had no role to play because the deed
did not contain any conflicting provisions requiring harmonization and
because the subject property was not burdened by a lease at the time of
conveyance (or before then). Id. at 907–08. The court thus applied
standard multiplication to determine the quantum of mineral interest
reserved. Id. at 908. With respect to the Mulkey parties’ alternative
claim, the court held that the presumed-grant doctrine did not apply,
primarily because there was no “gap” in the chain of title. Id. at 909.
II
We hold that the trial court and the court of appeals erred in
holding that the Mulkey parties do not have a 1/2 interest in the
5
minerals. Two distinct paths—the construction of the original deed and
the presumed-grant doctrine—lead us to the same conclusion. Not all
cases will require analysis of each path, so we address both to explain
how they differ and to identify their respective requirements.
First, we conclude that the deed itself reserved a 1/2 interest in
the mineral estate. Antiquated instruments that use 1/8 within a double
fraction raise a presumption that 1/8 was used as a term of art to refer
to the “mineral estate.” That presumption is readily rebuttable, however.
If the text itself has provisions—whether express or structural—
illustrating that a double fraction was in fact used as nothing more than
a double fraction, the presumption will be rebutted. But the presumption
is not rebutted here. Nothing in the text of this deed suggests that rote
multiplication was intended, and it is not inconsistent with any part of
the deed to read 1/8 as a term of art that references the entire mineral
estate. Even if we assumed for argument’s sake that this was wrong,
though, the presumed-grant doctrine would confirm that the Mulkey
parties today have title to 1/2 of the mineral estate. We address these
points in turn.
A
We begin by explaining how we construe the deed.
1
Whether the 1924 deed reserved a 1/2 mineral interest for the
Mulkey parties or a 1/16 interest—or anything else—reduces to a
question of textual interpretation. The fact pattern may seem odd to
those not steeped in Texas oil-and-gas law, but the legal framework for
6
analyzing this text is the same as for any other.
Unless otherwise defined in the text, courts will adopt a term’s
ordinary meaning. URI, Inc. v. Kleberg County, 543 S.W.3d 755, 763–
64 (Tex. 2018). One fundamental premise, however, is that a text
retains the same meaning today that it had when it was drafted.1 Thus,
the ordinary meaning at the time of drafting remains the meaning to
which courts must later adhere. We have made this basic point
repeatedly, even in the very double-fraction context that we confront
today: “Words must be given the meaning they had when the text was
adopted.” Hysaw v. Dawkins, 483 S.W.3d 1, 13 (Tex. 2016) (quoting
Antonin Scalia & Bryan A. Garner, Reading Law: The Interpretation of
Legal Texts 78 (2012)).
The meaning of an unamended text, in other words, is unaffected
by the passage of time, linguistic developments, or the evolution of usage.
These phenomena may affect our language by giving new meanings to
(or subtracting old meanings from) any given word or phrase. But the
original text does not evolve with the broader language. The test is what
the text reasonably meant to an ordinary speaker of the language who
would have understood the original text in its context. Whatever that
meaning was then remains the meaning today.
For example, early Texas jurisprudence recognized that a contract
for a “thousand” rabbits was understood to mean 1,200; reference to a
“day” could mean ten hours in context. Dwyer v. City of Brenham, 7 S.W.
1 While there are minor differences between statutory interpretation
and the interpretation of private instruments like contracts and deeds, the
fundamental principle at issue here—that words keep meaning what they
originally meant—is equally applicable to both.
7
598, 599 (Tex. 1888). Texts of that era using those terms still bear those
meanings. The way to change a text’s meaning is to change the text, not
to observe that an unchanged text includes language that, unbeknownst
to those who committed the text to writing, would at some point in the
future eventually carry a different meaning.
The U.S. Supreme Court’s decision in New Prime Inc. v. Oliveira,
139 S. Ct. 532 (2019), provides a recent illustration. The Court there
construed the term “contracts of employment” as used in the Federal
Arbitration Act, which Congress enacted in 1925. Today, “contracts of
employment” is a term of art that distinguishes those in formal
employment relationships from independent contractors. Id. at 539.
But the statute’s meaning turns on what that phrase meant in 1925, not
what it would mean today. The Court thus undertook careful analysis
of that phrase’s public meaning at the time of the statutory enactment.
It examined contemporary legal and lay dictionaries, judicial decisions,
federal and state statutes, and the like. Id. at 540–41. The Court agreed
that “modern intuition isn’t easily squared with evidence of the term’s
meaning at the time of the Act’s adoption in 1925,” when the term
“meant nothing more than an agreement to perform work.” Id. at 539.
In other words, “employment” was not used as a term of art in 1925. It
broadly meant work done regardless of the relationship between the one
doing the work and the one paying for it. That same meaning must
govern the Act today.
Thus, our analysis does not turn on what we might think “one-
half of one-eighth” would mean if written today. It does not matter
whether that phrase would clearly mean 1/16, or whether the now-
8
unusual step of spelling out a double fraction would make its meaning
inherently ambiguous, or something else. Indeed, the challenge is not
particularly legal in nature. Instead, it is to overcome the cognitive
dissonance that arises because, at least at first glance, “one-half of one-
eighth” seems unusually clear yet is alleged to mean something radically
different from what we might expect. After all, it is certainly true that
one-half times one-eighth did equal one-sixteenth in 1924 and at every
other time in history. But 1,000 has always meant 1,000 (not 1,200)
throughout history, too, even for rabbits; days have always had 24 hours,
not 10. Setting aside our preconceptions and our instinctive resort to
basic math, our only question is whether, in the context of a mineral-
conveyance instrument from 1924, the double fraction reasonably
referenced unchanging arithmetic at all. The analytical framework
here—simply determining what a term meant and thus means—turns
out to be exactly the same as it always is.
Precisely because we are addressing the ordinary process of
ascertaining a text’s meaning, we emphasize that the initial analysis
remains confined to the four corners of the document as usual. We said
that, too, in a case involving the double-fraction problem. See Garrett v.
Dils Co., 299 S.W.2d 904, 906 (Tex. 1957). Our interpretation of any
contract or deed primarily concerns the parties’ intended meaning. See,
e.g., Myers v. Gulf Coast Mins. Mgmt. Corp., 361 S.W.2d 193, 197 (Tex.
1962). But as always, we determine intent objectively by giving words
their fair meaning. Matagorda Cnty. Hosp. Dist. v. Burwell, 189 S.W.3d
738, 740 (Tex. 2006). We do not start with extrinsic evidence, nor do we
credit claims made in litigation of a secret or bespoke meaning that no
9
one not privy to the code reasonably would have understood. True,
“parties may freely define an ordinary word to have an unusual meaning;
when they do, they rebut the presumption of ordinary usage. Without
any textually expressed bespoke meaning, however, courts will adopt the
ordinary usage as a matter of law.” Perthuis v. Baylor Miraca Genetics
Lab’ys, LLC, 645 S.W.3d 228, 236 (Tex. 2022) (footnote omitted).
The question, then, is what the ordinary usage of the textually
undefined term “one-half of one-eighth” actually was. In other words,
we do not begin by asking what the original White and Mulkey parties
secretly or unusually might have meant by it. Merely indulging that
question at this stage of the analysis would invite a flood of unreliable
and destabilizing extrinsic evidence, which would be contrary to our
precedents and hostile to the rights of parties to have their documents’
meaning measured objectively without being undermined by a later
(perhaps much later) subjective inquiry.
Deeds provide a good example of why we insist on language
bearing its ordinary meaning. Recording deeds and similar instruments
is purposefully a public enterprise designed to elicit public reliance.
“[T]he reliability of record title contributes mightily to the predictability
of property ownership that is so indispensable to our legal and economic
systems.” Cosgrove v. Cade, 468 S.W.3d 32, 34 (Tex. 2015). A properly
recorded deed, like the one at issue here, “provides all persons, including
the grantor, with notice of the deed’s contents,” id., which would be far
less valuable without a consistent and stable judicial construction of
terms used in deeds. The meaning of a deed, in other words, matters to
the public writ large, not merely to those who wrote it. So important is it
10
that these records are public and permanent that we recently overturned
a decades-old default judgment foreclosing a tax lien largely because of
the failure “to consult public deed and tax records,” which would have
revealed information necessary to achieve proper service on a defendant.
Mitchell v. MAP Res., Inc., 649 S.W.3d 180, 191 (Tex. 2022).
We therefore ask, as the Court in New Prime did, whether there
is some objective reason that the double fraction in the deed at issue
meant something other than its arithmetical result. URI, 543 S.W.3d
at 765. Said differently, using extrinsic evidence of subjective intent to
inform the language that the specific parties used would impermissibly
trespass beyond the document’s four corners. Courts frequently consult
contemporary dictionaries because they convey objective and generally
available—not subjective or bespoke—guides to meaning. Specialized
or technical dictionaries can provide the same assistance for texts that
arise in specialized or technical contexts. Indeed, the types of generally
available sources that the Court used in New Prime to confirm that the
meaning of “contracts of employment” has changed over time can benefit
textual analyses of all kinds. The goal of such an inquiry is always to
determine what a text could reasonably have meant to an informed but
disinterested speaker at the time the text was written.
Determining what a text would have meant to a disinterested
audience is an inquiry that is designed to confine courts to the four
corners of the document and is a proper part of interpretation. See, e.g.,
U.S. Shale Energy II, LLC v. Laborde Props., L.P., 551 S.W.3d 148, 152
(Tex. 2018) (“We may consider such circumstances to the extent they
‘inform, rather than vary from or contradict, the [instrument’s] text.’ ”
11
(quoting URI, 543 S.W.3d at 767)). As we discuss below, only if the text
remains incapable of a clear meaning—and thus is unavoidably
ambiguous—would we then move beyond the traditional, neutral, and
objective tools of textual analysis.
2
This brings us to the now-familiar observation that, at the time
the parties executed this deed, “1/8” was widely used as a term of art to
refer to the total mineral estate. Notably, it is that fraction—not 1/3,
2/7, 6/241, or any other—that is so repeatedly deployed. Happily, we
need not speculate as to why. Hysaw recently undertook the core
analysis on which we rely today.
The Court there examined what it called the “Double-Fraction
Dilemma” in the context of a 1947 will-construction dispute where a
provision of the will bequeathed each child a “one-third of one-eighth
royalty.” Hysaw, 483 S.W.3d at 4. While recognizing that “[d]iscerning
the nature of a particular royalty interest may be a simple matter when
an instrument consistently uses single fractions to describe the interest,”
double fractions can present serious complications. Id. at 9. The Court
looked to the objective circumstances as a necessary part of defining the
terms in their context. Id. at 9–15. The Court identified two related
circumstances that explain why 1/8 in such instruments did not typically
bear its arithmetical meaning: the historical use of 1/8 as the standard
royalty and the estate-misconception theory. Id. at 8.
Because these historical features confirmed that 1/8 was a widely
used term of art, the Court expressly rejected “a mechanical approach
requiring rote multiplication of double fractions whenever they exist.”
12
Id. at 4. Instead of simple multiplication, we held that “[i]ntent must be
determined by a careful and detailed examination of the document in its
entirety, rather than by application of mechanical rules of construction
that offer certainty at the expense of effectuating intent.” Id. at 16.
Applying this analysis, the Court found that the term “one-third of one-
eighth royalty” did not intend to relay a fixed 1/24 royalty, but instead
a floating 1/3 interest in the royalty. Id. at 5.
Hysaw provides the foundation for resolving this case and many
others. Nonetheless, it remains true that “[t]he proper construction of
instruments containing double-fraction language is a dilemma of
increasing concern in the oil and gas industry, as uncertainty abounds,
disputes proliferate, and courts have seemingly varied in their
approaches to this complicated issue.” Id. at 4. This “complicated issue”
is a manifestation of the temporal context in which this deed was
executed. We therefore briefly review the two widespread and related
faulty conceptual culprits referenced in Hysaw—the estate-misconception
theory and the use of 1/8 as the standard royalty—that worked in tandem
to lead parties to use the term “1/8” to describe something other than a
literal eighth. True, it matters less why the term was used in a particular
way than that it was so widely used, but understanding the reason helps
eliminate any lingering doubts.
The estate-misconception theory reflects the prevalent (but, as it
turns out, mistaken) belief that, in entering into an oil-and-gas lease, a
lessor retained only a 1/8 interest in the minerals rather than the entire
mineral estate in fee simple determinable with the possibility of reverter
of the entire estate. Id. at 10; Concord Oil Co. v. Pennzoil Expl. & Prod.
13
Co., 966 S.W.2d 451, 460 (Tex. 1998). Therefore, for many years, lessors
would refer to what they thought reflected their entire interest in the
“mineral estate” with a simple term they understood to convey the same
message: “1/8.”2 This widespread and mistaken belief ran rampant in
instruments of this time involving the reservation or conveyance of a
mineral interest—so much so that courts have taken judicial notice of
this widespread phenomenon. Hysaw, 483 S.W.3d at 9–10. Therefore,
the very use of 1/8 in a double fraction “should be considered patent
evidence that the parties were functioning under the estate
misconception.” Laura H. Burney, The Regrettable Rebirth of the Two-
Grant Doctrine in Texas Deed Construction, 34 S. Tex. L. Rev. 73, 90
(1993). We made this point in Hysaw, citing “commentators” who have
observed that “there is ‘little explanation’ for the use of double fractions
to express a fixed interest absent a misunderstanding about the
grantor’s retained ownership interest or use of 1/8 as a proxy for the
customary royalty.” 483 S.W.3d at 10–11.
The second rationale—the special meaning that 1/8 acquired in
the standard-royalty context—provides an additional objective indication
of what parties meant by using 1/8 within a double fraction. We said in
Hysaw that we had “no doubt” that “[t]he near ubiquitous nature of the
2 Laura H. Burney, The Regrettable Rebirth of the Two-Grant Doctrine
in Texas Deed Construction, 34 S. Tex. L. Rev. 73, 88 (1993) (“Since most leases
provide for a 1/8 royalty, however, drafters and courts perceived the estate to
be a fee simple determinable in only 7/8 in the lessee, with the lessor retaining
a 1/8 fee interest. This misconception stems from a failure to distinguish
between the mineral estate owner’s right to receive royalties and the value
placed on that right in the lease. Although the lessor only retains a 1/8 royalty
interest, the lessor still has a possibility of reverter in the entire mineral
estate.” (emphasis added) (footnote omitted)).
14
1/8 royalty—dubbed by some as ‘the legacy of the 1/8 royalty’ or
‘historical standardization’”—is something that “influenced the language
used to describe the quantum of royalty in conveyances of a certain
vintage.” Id. at 9–10. This prevalent belief and confusion resulted in
parties mistakenly assuming the landowner’s royalty would always be
1/8. Therefore, parties would use the term 1/8 as a placeholder for future
royalties generally—without anyone understanding that reference to set
an arithmetical value. Once again, this pervasive misunderstanding
long ago led us to take judicial notice in this specific context of double-
fraction royalties. Garrett, 299 S.W.2d at 907.
Working in tandem, these widely recognized principles provide
objective indications about what the parties to this deed meant by
deploying a double fraction. At that time, the fraction 1/8 had various
meanings that linked to the landowner’s conception of the entirety of the
estate. We are, frankly, not aware of double fractions including 1/8 that
were aimed at simple multiplication rather than referencing the mineral
estate as a whole. But that does not mean it could not have happened.
To account for the possibility that parties to an instrument may have
intended nothing more than multiplication, the Court in Hysaw rejected
a one-size-fits-all arithmetical solution in which deeds or other documents
using 1/8 would inexorably be treated as referring to the entire mineral
estate, as alluring as that (or any other bright-line) solution would be.
Instead, we required a full contextual analysis of an instrument when
construing a relevant mineral conveyance of that era, like the deed in
the present case. See Hysaw, 483 S.W.3d at 10–12.
15
3
We now reaffirm Hysaw and clarify the import of our holding in
that case. Specifically, when courts confront a double fraction involving
1/8 in an instrument, the logic of our analysis in Hysaw requires that we
begin with a presumption that the mere use of such a double fraction
was purposeful and that 1/8 reflects the entire mineral estate, not just
1/8 of it. Indeed, it would be odd to say “one-half of one-eighth” rather
than simply “one-sixteenth” if all that was intended by “one-half of one-
eighth” was 1/16. See id. (discussing the need “to accord . . . significance
to the use of double fractions in lieu of a single fraction”). Our analysis
in Hysaw thus warrants the use of a rebuttable presumption that the
term 1/8 in a double fraction in mineral instruments of this era refers to
the entire mineral estate. Because there is “little explanation” for using
a double fraction for any other purpose, id. at 10, this presumption
reflects historical usage and common sense.
At the same time, Hysaw clarifies that the presumption is readily
and genuinely rebuttable. As we made clear in that opinion, every
contract, deed, or will is free to manifest a different intent and to define
terms in different ways. See id. at 14 (“all the other language in the
document must be considered to deduce intent”). Any instrument may
be unique, and the judicial role is to ensure that individual parties
receive a faithful interpretation of their legal instrument. Thus, the
entire instrument should be examined to determine whether its text
rebuts the presumption. We emphasize that the rebuttal must come
from the document itself, given the public’s right to rely on the meaning
of deeds and our general insistence on predictability and stability in
16
matters of interpretation.
Frequently, of course, examining the entire instrument will reveal
provisions that confirm the presumption. Often, those additional
provisions would make sense only if 1/8 is read as a term of art, as was
true in Hysaw itself. No one has presented us with examples of parties
to instruments of the relevant era who used a double fraction just for its
arithmetical purpose, but courts should be ready to find not just
confirmation but contradictions of the presumption. A rebuttal could be
established by express language, distinct provisions that could not be
harmonized if 1/8 is given the term-of-art usage (the mirror image of
Hysaw), or even the repeated use of fractions other than 1/8 in ways that
reflect that an arithmetical expression should be given to all fractions
within the instrument.3 In such cases, the rebuttal may be sufficiently
clear that, as a matter of law, the double fraction can only be held to
require simple multiplication. The key point is that there must be some
textually demonstrable basis to rebut the presumption.
Nor do we foreclose the possibility that an instrument may have
enough textual evidence to drain confidence in the presumption yet
insufficient evidence for a court to conclude that a reasonable reader at
the time would have understood the instrument to require mere
multiplication. In such a case, and if our ordinary rules of construction
3 Hypothetically, for example (we are aware of no real-world example
like this), an instrument could have a series of double fractions—a list of
conveyances in the form of double fractions, some of which use 1/8 and others
that do not, thus suggesting that the double fractions were included not because
of any term of art but because listing both fractions was meaningful in showing
how the multiple allocations were reached.
17
are incapable of generating a single answer, then our case law involving
inescapable ambiguity—including the authorized but reluctant recourse
to extrinsic evidence—provides the next step. When that happens, a
factfinder may be needed to finally resolve the text’s meaning. Courts
should endeavor to give meaning to the text without too hastily finding
ambiguity, but there may be times in which no other choice remains.4
In short, in Hysaw we rejected both available Procrustean
solutions—insisting on always multiplying the double fraction or
insisting on never doing so—even though the attraction of adopting
either is self-evident. The approach that we describe today avoids the
arbitrary, unfair, and inaccurate results that would necessarily follow
from adopting either extreme. But it also avoids reinventing the wheel
in every individual case. This rule is thus flexible even as it advances
stability and predictability from case to case. Wasteful litigation
involving double fractions seems destined to proliferate absent clear
guidance for the courts and the public.
4
Given these principles, we cannot affirm the judgment below. The
court of appeals concluded that it had no basis to do anything other than
multiply the fractions. The estate-misconception theory played no role,
that court concluded, because there were no inconsistencies to reconcile
4 As we discuss below, see infra Part II.B, other legal principles—like
the presumed-grant doctrine—may require courts to fix present-day ownership
regardless of what the original text provided. In such a case, interpreting the
original instrument would at most provide an alternative holding such that a
court could exercise its discretion not to reach that question at all.
18
within the deed and because the property was not burdened by a lease
at the time of conveyance (or at any time prior). 647 S.W.3d at 907–08.
We respectfully disagree with this analysis because we think it
misapprehends how the estate-misconception theory affects the reading
of instruments like the deed in this case. Specifically, the theory’s
relevance has never depended on the considerations that the court of
appeals identified. We agree, of course, that this case somewhat differs
from Hysaw and others that we have analyzed; such cases often did
require a harmonization of conflicting provisions within the text.5 But we
have never suggested a default rule that requires multiplication unless
it can be proven that doing so would contravene some other provision of
the text.6 Such a rule would ahistorically require us to read many double
fractions as pointless—as though the parties just did not know how to
complete a simple exercise in multiplication. As we explained in Hysaw,
and as we reiterated above, the very use of the double fraction is itself
the primary reason to presume purposefulness. And the temporal context
of this deed indicates that those factors are clearly present here.
Accordingly, identifying a lack of inconsistent provisions that
require harmonization gets the analysis backwards. The use of a double
fraction in this deed, combined with the lack of anything that could

v. White, 819 S.W.2d 459, 464–65 (Tex. 1991); and Concord Oil Co., 966 S.W.2d
at 454–55.
6 Hysaw does not limit its application in this way. Instead, it refers to
the “Double-Fraction Dilemma” and estate-misconception theory as a product
of “[i]nstruments employing double fractions to convey or reserve mineral
interests.” 483 S.W.3d at 9.

rebut the presumption, is precisely why we can conclude as a matter of
law that this deed did not use 1/8 in its arithmetical sense but instead
reserved to the Mulkey grantors a 1/2 interest in the mineral estate.
B
Even if we were less persuaded by the double-fraction analysis,
however, the Mulkey parties argue that we still would have to recognize
their present-day ownership of one-half of the mineral estate. That is,
even if the “one-half of one-eighth” reservation meant only a 1/16
mineral interest in 1924, they argue that the record conclusively
establishes that they acquired the other 7/16 interest through the
presumed-grant doctrine. The court of appeals disagreed, concluding
that the presumed-grant doctrine played no role. 647 S.W.3d at 908–10.
We agree with the Mulkey parties. The presumed-grant doctrine,
“also referred to as title by circumstantial evidence, has been described
as a common law form of adverse possession.” Fair v. Arp Club Lake,
Inc., 437 S.W.3d 619, 626 (Tex. App.—Tyler 2014, no pet.). The doctrine
requires its proponent to establish three elements: (1) a long-asserted
and open claim, adverse to that of the apparent owner; (2) nonclaim by
the apparent owner; and (3) acquiescence by the apparent owner in the
adverse claim. Magee v. Paul, 221 S.W. 254, 257 (Tex. 1920).
The court of appeals imposed an additional fourth element: a gap
in the title. 647 S.W.3d at 909.7 Satisfying the doctrine is properly
7 Or, more precisely, the court of appeals made the “gap” a kind of
condition. Specifically, the court of appeals acknowledged that the “gap”
requirement “is not an express element” but went on to hold that the doctrine
“typically applie[s] . . . in cases where a party’s lack of complete record title to
land it has claimed for a long time is due to a gap in the chain of title.” 647

difficult, but neither our precedent nor the doctrine’s underlying purposes
support mandating this additional test. Nonetheless, the extensive
history of transactions and dealings detailed below, accompanied by the
1946 letter, provides enough evidence for the existence of such a gap
even if it were needed.8
We think that the parties’ history of repeatedly acting in reliance
on each having a 1/2 mineral interest conclusively satisfies the
presumed-grant doctrine’s requirements. This ninety-year history
includes conveyances, leases, ratifications, division orders, contracts,
probate inventories, and a myriad of other recorded instruments that
provided notice. There was a long and asserted open claim—for nearly
a century, both parties acted in accordance with each side owning a 1/2
interest. And until this litigation began in 2013, the White parties never
said anything to the contrary.
Indeed, this evidence long predates and continually postdates the
1946 letter. That fact simultaneously supplies evidence for the presumed-
grant doctrine if it is actually needed and adds to our confidence that our
reading of the deed is correct.9 For example, in 1926—just two years
S.W.3d at 909. But insisting on the presence of such a “gap,” as in the
judgment below, amounts to the same thing as making it an element.
8 That is, if the 1946 letter reflected a common understanding at that
time that the Mulkey parties held only a 1/16 interest, so that a new conveyance
was needed to bring them to parity with the White parties, evidence of the gap
would appear in (1) the absence of the contract or new deed combined with
(2) another 67 years of unbroken post-letter conduct by all parties acting
consistently with both sides having an equal interest.
9 We hasten to emphasize that the secondary analysis here involving
the extrinsic evidence of transactions and history between the parties is not
probative in the initial analytical process we described in Part II.A, supra,
21
after the deed’s execution—the White parties acknowledged in a Purchase
and Escrow Agreement with an oil company that they owned only half
of the minerals and that the other half belonged to the Mulkey parties.
The corresponding documents provide further support by indicating that
after both parties leased their respective mineral interests, each side was
to receive an equal share of the royalties.
The White parties point to another transaction occurring in 1926
in which the Mulkey parties conveyed a 1/16 interest in the minerals to
a third party. That 1/16 interest, however, refers to the mineral interest
of an entirely different property, not any property subject to this lawsuit.
We cannot see how a wholly distinct transaction sheds any light on the
one before us. And our doubts about relevance are heightened because
that 1926 transaction illustrates that the very same grantors could (and
did) refer to a 1/16 interest directly and not via the circumlocution of a
double fraction. When what they actually wanted was to convey exactly
and mathematically a 1/16 interest, that is precisely what they did.
Regardless, the parties’ history marches on, particularly around
the time of the 1946 letter and beyond. For example, the very week of
the 1946 letter, the Mulkey parties executed an “Agreement for Division
of Rentals and Royalties” with multiple recitals stating that they
“own[ed] an undivided one-half interest in said minerals . . . .” Whether
this was undertaken in conjunction with the supposed “contract” is
unknown—but that it was undertaken is all that matters.
because it would go beyond the text. While these transactions confirm our
textual conclusion, they are formally relevant only to the Mulkey parties’ claim
under the presumed-grant doctrine, which is why they present this evidence.
22
Further, again around the time of the letter, both parties leased
their respective mineral interests to the same lessee, and the leases once
again reflected that each party owned 1/2 of the mineral estate. The
White parties filed their own recorded stipulation stating the amount of
delay rentals to which they were entitled under the lease; again, the
amount was consistent with the reflection that they claimed only a 1/2
interest of the mineral estate rather than the 15/16 interest they now
assert. On top of this, several accompanying documents, including the
division of interests and rentals, relayed the same understanding.
Similar transactions occurred again in the late 1950s, including when
G. R. White himself recited that he owned only an “undivided one half
(1/2) interest” in “all of the oil, gas, and other minerals” on the ranch.
And a series of conveyances in 1973 revealed the same thing.
These transactions continued until 2012, when Endeavor Energy
drilled a well that established oil and gas production on the subject
ranch land and paid both parties their respective royalty interests—1/2
to the Mulkey parties and 1/2 to the White parties. Some of the White
parties then, for the first time, alleged ownership of 15/16 of the mineral
estate. But the filing of this lawsuit in 2013 cannot negate nearly a
century of overwhelming evidence that the White parties never
previously made such a claim in all those years. In fact, all the
transactions suggest that the White parties understood and intended
the Mulkey parties to have a 1/2 interest.10 Accordingly, if the
10Given the unbroken chain of transactions and representations by both
sides before and after the 1946 letter, it may well be that the “contract” it
mentioned was merely a joint response to someone’s (a lawyer’s?) recognition
that the use of double fractions relied on mistaken premises. Perhaps a future
23
presumed-grant doctrine were in fact necessary, we would find that the
Mulkey parties have conclusively established it.11
III
We conclude that the Mulkey parties hold title to 1/2 of the mineral
estate because the original deed so requires and because the presumed-
grant doctrine would remove any remaining doubts. Because the court
of appeals held otherwise, we reverse its judgment and remand to the
trial court for further proceedings.12

dispute was envisioned, along with a desire to bring clarity to the record by
eliminating all doubt for coming generations. If so, it is a misfortune that the
contract or replacement deed was not filed, because that simple step would
have removed the need for the present litigation.
11 When historical records are sufficiently clear to implicate the
presumed-grant doctrine’s demanding requirements, the result could cut
either way—in favor of or contrary to the party invoking the double-fraction
presumption. Either side, therefore, could find the doctrine to be important.
In cases where the presumed-grant doctrine is clearly implicated, a court could
dispense with the deed-construction analysis.
12 The procedural posture of this case leads us to remand to the district
court rather than to render judgment. The district court granted the White
parties’ motion for summary judgment with respect to the construction of the
deed but had no corresponding motion on that issue from the Mulkey parties.
On remand, the parties and the district court may determine the extent to
which further proceedings are necessary in order to produce a final judgment.
