ON PETITION FOR REHEARING
PATRICK E. HIGGINBOTHAM, Circuit Judge:Treating Appellants’ Petition for Rehearing En Banc as a Petition for Panel Rehearing, the Petition for Panel Rehearing is DENIED, but we amend the prior opinion, 722 F.3d 700 (5th Cir.2013), solely to add footnote 30. As amended, the opinion is as follows:
In this case, mortgagors who defaulted on their note seek to enjoin a bank from foreclosing, contending that the assignments by which the bank obtained the note and corresponding deed of trust were “robo-signed” and therefore invalid. The district court granted the bank’s motion to dismiss. We affirm.
I.
In February 2004, Dia and Joseph Rein-agel, the appellants, purchased a property in Helotes, Texas for $307,840, obtaining the necessary financing from a mortgage lender not party to this appeal. In May 2006, the Reinagels refinanced, obtaining a $360,000 home-equity loan from Argent Mortage Company, LLC (“Argent”) in exchange for a promissory note as well as a deed of trust securing the note.1 Argent apparently sold the Reinagels’ loan to Deutsche Bank National Trust Company (“Deutsche Bank”), the appellee, shortly after origination, at which point Deutsche Bank pooled it with other mortgage loans in a securitization transaction and sold the resulting mortgage-backed securities to investors. As alleged in the amended complaint, the Pooling and Servicing Agreement (“PSA”) that governed the trust in which Deutsche Bank, as trustee, held the mortgage loans provided that no loans could be transferred into the trust after October 1, 2006.
Notwithstanding the PSA’s closing date, neither Argent nor Deutsche Bank formally documented the sale of the Reinagels’ loan until January 23, 2008, a date that roughly coincides with the zenith of the subprime mortgage crisis.2 On that date, a Ms. Dawn L. Reynolds, purporting to act as the “authorized agent” of “Citi Residential Lending, Inc...., [a]ttorney-in-[f]act *223for Argent,” executed an instrument assigning the deed of trust “to Deutsche Bank ..., as Trustee, in trust for the registered Holders of Argent Securities Inc., Asset-Backed Pass-Through Certificates, Series 2006-MI.” Ms. Reynolds acknowledged her signature before a California notary and the instrument was filed and recorded in Bexar County on January 30, 2008. The instrument does not reference the promissory note secured by the deed of trust.
On February 13, 2009, more than a year after the initial assignment, a Mr. Brian Bly executed a second instrument assigning the deed of trust to Deutsche Bank, purporting to act in his capacity as -“Vice President” of “Citi Residential Lending, Inc., ... attorney-in-fact for Argent.” Unlike the first assignment, however, the second instrument also expressly transferred “the certain note(s) described [in the deed of trust] together with all interest secured thereby, all liens, and any rights due or to become due thereon.” Mr. Bly acknowledged his signature before a Florida notary and the instrument was e-filed and e-recorded in Bexar County on February 17, 2009.
At some point in 2009 or early 2010, the Reinagels defaulted on the note, and in April 2010, Deutsche Bank sought a judicial order authorizing foreclosure. Deutsche Bank asserted that it was a “mortgagee” under Texas Property Code § 51.0001(4) and therefore had the right to foreclose on the Reinagel’s property. Under § 51.0001(4), a mortgagee can be (1) “the grantee, beneficiary, owner, or holder of a [deed of trust],” or (2) “if the [deed of trust] has been assigned of record, the last person to whom the [deed of trust] has been assigned of record.”3 Deutsche Bank claimed that it qualified as a mortgagee on either wing; as the 2008 and 2009 assignments rendered it owner and holder, as well as assignee of record, of the deed of trust. The state court apparently agreed, granting the order.
In October 2011, the Reinagels filed suit in Texas state court to temporarily enjoin the foreclosure and obtain a declaratory judgment that Deutsche Bank lacked standing to foreclose. The Reinagels claimed that the 2008 and 2009 assignments were both “robo-signed” and therefore void. “Robo-signing” is the colloquial term the media, politicians, and consumer advocates have used to describe an array of questionable practices banks deployed to perfect their right to foreclose in the wake of the subprime mortgage crisis, practices that included having bank employees or third-party contractors: (1) execute and acknowledge transfer documents in large quantities within a short period of time, often without the purported assignor’s authorization and outside of the presence of the notary certifying the acknowledgment,4 and (2) swear out affidavits confirming the existence of missing pieces of loan documentation, without per*224sonal knowledge and often outside of the presence of the notary.5
The state court granted the Reinagels’ request for a temporary injunction, setting trial for June 4, 2012. On November 21, 2011,- Deutsche Bank removed the Reina-gels’ suit to the Western District of Texas, invoking diversity. In their amended complaint, the Reinagels elaborated on then-allegations of “robo-signing,” claiming that the January 2008 assignment was void because Ms. Reynolds “appears to be an employee of Citi Residential Lending[,] [Inc.] and not Argent,” and that the February 2009 assignment was void because Mr. Bly purported to execute it as “Vice President of Citi ... as attorney in fact for Argent” when he in fact worked for a third-party contractor, Nationwide Title Clearing. The Reinagels also asserted that the second assignment was void as a forgery, as “Mr. Bly’s own deposition testimony taken in another case indicates that his signature was simply ‘scanned’ onto documents and then notarized as an original and recorded.” Finally, the Reinagels claimed, both assignments were void as violating the PSA, which specified that no mortgage could be transferred into Deutsche Bank’s pooling trust after October 1, 2006.
Deutsche Bank moved to dismiss the Reinagels’ amended complaint, urging that the Reinagels lacked standing to challenge the validity of the 2008 and 2009 assignments because they were not parties to those agreements. In the alternative, Deutsche Bank argued that “ ‘robo-signing’ claims are not applicable to assignments,” because “an assignment is a contract, and is distinguishable from an affidavit, which is the document typically challenged in connection with ‘robo-sign-ing’ allegations.” Finally, though Deutsche Bank did not dispute that the assignments violated the PSA, it argued that the Reinagels lacked standing to enforce that agreement.
The district court granted Deutsche Bank’s motion. Though the court “disagree[d] with [Deutsche Bank’s] argument that the invalidity of the assignments would have no impact on its ability to foreclose,” it concluded that “[the Reina-gels’] allegations of invalidity fail as a matter of law.” First, the court reasoned, the Reinagels pointed to “no case that has invalidated an assignment because it was robo-signed.” Second, the court observed, “[the Reinagels] cite no authority for the proposition that the violations of the PSA make the assignment invalid, and due to th[eir] lack of standing, they cannot assert [a] claim for breach of the PSA itself.” The Reinagels appeal.
II.
The first issue on appeal is whether the Reinagels have standing to challenge the validity of the transactions by which Argent, the loan originator, purportedly assigned the deed of trust and corresponding promissory note to Deutsche Bank. Deutsche Bank urges that “the law is well settled that a stranger to a contract lacks standing to challenge [that] contract,” and that “[n]umerous federal district courts have recognized that plaintiffs lack standing to challenge the assignment of security instruments in cases similar to the present.” The Reinagels rejoin that “Texas state and federal courts routinely allow a homeowner to challenge the chain of assignments by which a party claims a right to foreclose,” dismissing the cases relied upon by Deutsche Bank as incorrectly decided.
We agree with the Reinagels. To be sure, Texas courts have held that a non-*225party to a contract cannot enforce the contract unless she is an intended third-party beneficiary,6 occasionally couching this principle in terms of “standing.”7 Here, however, the Reinagels are not attempting to enforce the terms of the instruments of assignment; to the contrary, they urge that the assignments are void ab initio. Though “the law is settled” in Texas that an obligor cannot defend against an assignee’s efforts to enforce the obligation on a ground that merely renders the assignment voidable at the election of the assignor, Texas courts follow the majority rule that the obligor may defend “on any ground which renders the assignment void.”8 A contrary rule would lead to the odd result that Deutsche Bank could foreclose on the Reinagels’ property though it is not a valid party to the deed of trust or promissory note, which, by Deutsche Bank’s reasoning, should mean that it lacks “standing” to foreclose.
III.
The next question is whether the Reina-gels’ allegations, taken as true, establish that Deutsche Bank lacks authority to foreclose under the deed of trust. To answer this question, we begin by examining whether the first assignment is itself sufficient to convey such authority, or whether both assignments are necessary— an issue not addressed by the parties and ignored by the district court. As aforementioned, the first instrument assigned only the deed of trust, whereas the second instrument assigned both the deed of trust and “the certain note(s) described therein.” Presumably, Deutsche Bank arranged the second conveyance because of the common-law rule that the assignment of a mortgage alone is a nullity,9 a rule based on the intuitive principle that a party seeking to foreclose must have the right to enforce the debt it seeks to satisfy.10 However, under the Restatement (Third) of Property: Mortgages, the transfer of a mortgage presumptively includes the note secured by the mortgage, whether or not the instrument of assignment expressly references the note.11 Under the Restatement’s approach, then, the first assignment is itself sufficient to give *226Deutsche Bank authority to foreclose, and the validity of the second assignment is irrelevant.12 Texas courts tend to follow the Restatement;13 however, as they have never expressly adopted its note-follows-the-mortgage presumption,14 we examine the Reinagels’ objections to both instruments.
The Reinagels challenge the validity of the first instrument on the ground that Ms. Reynolds executed it as the “authorized agent” of Argent even though she was employed by Citi Residential Leasing, Inc. (“Citi”), implying — but never directly asserting — that Reynolds must have therefore lacked authority to execute the assignment. However, as reflected in the attachments to the pleadings, Reynolds signed as the “authorized agent” of “Citi ..., [a]ttorney-in-[f]act for Argent.” As the Reinagels conspicuously fail to allege either that Ms. Reynolds lacked authority to act on behalf of Citi or that Citi lacked authority to act on behalf of Argent — -let alone plead facts to support such allegations — there is no record basis for concluding that Ms. Reynolds misrepresented the scope of her authority in executing the assignment. In short, the Reinagels’ challenge to the validity of the first assignment fails on its own terms.
Turning to the second assignment, the Reinagels challenge it as void because Mr. Bly executed the instrument as “Vice President” of Citi — Argent’s authorized agent — even though he was actually an employee of a third-party contractor, Nationwide Title Clearing. However, in Nobles v. Marcus,15 the Texas Supreme Court clarified that a contract executed on behalf of a corporation by a person fraudulently purporting to be a corporate officer is, like any other unauthorized contract, not void, but merely voidable at the election of the defrauded principal — here, Citi (or Argent through Citi).16 As “[Texas] law is settled that the obligors of a claim ... may not defend [against an assignee’s effort to enforce the obligation] on any ground which renders the assignment voidable only,”17 Bly’s alleged lack of authority, even accepted as true, does not furnish the Reinagels with a basis to challenge the second assignment.18
*227The Reinagels also contend that the second assignment is void as a “forgery,” reasoning that Bly “has testified that his signature was scanned onto documents and then notarized as an original.” This argument is a red herring. Texas recognizes typed or stamped signatures— and presumably also scanned signatures— so long as they are rendered by or at the direction of the signer,19 and the Reinagels do not allege that Bly’s signature was scanned onto the document without his authorization.20 Moreover, acknowledgments are valid as long as they are made in the presence of the notary and meet certain other formalities the Reinagels do not challenge here; there is no requirement that the affiant affix his signature in wet ink.21 Finally, even if Bly’s acknowledgment is defective,22 counsel for the Reinagels conceded during oral argument “that there is no dispositive law that says [an assignment of a deed of trust] has to be a notarized document.”23 While mortgage assignments must be acknowledged to be recorded,24 Texas’s recording statute protects only subsequent purchasers for value and without notice.25 That is, while defects in the acknowledgment might prevent Deutsche Bank from foreclosing had a third party purchased the underlying real estate from the Reinagels without actual knowledge of the mortgage,26 they do *228not affect Deutsche Bank’s rights against the Reinagels.27
Finally, the Reinagels claim that both assignments are void because they violated the PSA that governed Deutsche Bank’s Series 2006-MI mortgage pool. True enough, the PSA provided that no mortgages could be transferred into Deutsche Bank’s pooling trust after October 1, 2006 — more than a year before the first assignment. But as the Reinagels concede that they are not party to the PSA, they have no right to enforce its terms unless they are its intended third-party beneficiaries. The Texas Supreme Court has established “a presumption ... that parties contracted for themselves,” which applies “unless it ‘clearly appears’ that they intended a third party to benefit from the contract.”28 Here, the Reinagels claim that they are third-party beneficiaries because the PSA was an integral part of a securitization transaction that enabled them to obtain a home-equity loan; however, they fail to state any facts indicating that the parties to the PSA intended that benefit.29 Moreover, even assuming that the Reinagels are third-party beneficiaries, the fact that the assignments violated the PSA — a separate contract — would not render the assignments void, but merely entitle the Reinagels to sue for breach of the PSA.
In sum, the first assignment is valid and, under the Restatement’s note-follows-the-mortgage presumption, vests Deutsche Bank with authority to foreclose on the Reinagels’ property.30 However, because the second assignment is also valid — at least as against the Reinagels — we need not determine today whether the Texas Supreme Court would follow the Restatement. Our holding is a narrow one: we merely reaffirm that under Texas law, facially valid assignments cannot be challenged for want of authority except by the defrauded assignor. We do not condone “robo-signing” more broadly and remind that bank employees or contractors who commit forgery or prepare false affidavits subject themselves and their supervisors to civil and criminal liability.
*229IV.
The judgment of the district court is AFFIRMED.
. Though a deed of trust is formally distinct from a mortgage, Texas courts tend to use the two terms interchangeably. For purposes of this appeal, we do the same.

It is conceivable that on rare occasions a mortgagee will wish to disassociate the obligation and the mortgage, but that result should follow only upon evidence that the parties to the transfer so agreed. The far more common intent is to keep the two rights combined.... This section's purpose is generally to achieve the same result even if one of the two aspects of the transfer is omitted.

. Notably, the Reinagels do not argue that Deutsche Bank must produce the original, wet-ink note in order to foreclose. As the Reinagels concede, most courts, including district courts in this Circuit, have rejected the “show-me-the-note” defense, holding that though a mortgagee must establish that it owns the note to foreclose, it need not produce the original.

. See Nobles, 533 S.W.2d at 926-27 ("It is settled that ... a deed [executed by a person fraudulently misrepresenting his agency] is valid and represents prima facie evidence of title until there has been a successful suit to set it aside ... [which] can only be maintained by the defrauded [principal].”).

. Indeed, the Reinagels attribute the scanning to Bly, claiming that "Mr. Bly’s conduct clearly falls within th[e] provision [of the Texas Penal Code that criminalizes forgery]'' (emphasis added).
. See Tex. Civ. Pract. & Remedies Code §§ 121.004, 121.007.
. The Reinagels allege that Bly’s signature was scanned onto the assignment, an allegation from which one might infer that Bly did not actually "appear before" the notary as required to render an acknowledgment valid under Texas law. Tex. Civ. Pract. & Remedies Code § 121.004. The concurrence concludes that such a defect in the acknowledgment may render the underlying assignment a forgery. We disagree. Texas contract law is clear that "[fjorgery is the making without authority of a false instrument in writing, purporting to be the act of another." Nobles, 533 S.W.2d at 926 (emphasis added). Here, Bly executed the assignment, and the Reina-gels do not allege that Bly's signature was forged without his authorization. Indeed, they suggest that Bly himself scanned his signature onto the document. Hence, the underlying assignment is not void as a forgery. Cf. 1A C.J.S. Acknowledgments § 10 (2013) (“An acknowledgment of an instrument is not the same as the instrument itself. Thus, except where formal acknowledgment is made essential to the validity of an instrument by statute, where an attempted acknowledgment is defective or irregular, the instrument is not thereby invalidated as between the parties, or their heirs, or representatives.”).
. See, e.g., C.J.S. Mortgages § 417 (2013) ("[I]t is not necessary to the validity of an assignment of a mortgage that it should be acknowledged or attested by witnesses.”).
. Tex. Prop.Code. § 12.001(b).
. Tex. Prop.Code. § 13.001(a). It matters not that the Texas Property Code defines "mortgagee” to include "the last person to whom [the deed of trust] has been assigned of record," as this definition is not exhaustive and applies only "if the [deed of trust] has been assigned of record.” See Tex. Prop.Code § 51.0001(4). The definition of "mortgagee” also includes "the grantee, beneficiary, owner, or holder of [the deed of trust],” see id. (emphasis added), a definition broad enough to accommodate assignees who fail to record.
. We use the term "might” deliberately, as "the general rule ... is that a defect in the acknowledgment of an instrument ..., which is not apparent on the face of the instrument ... does not prevent the recordation from being constructive notice to persons who may *228be affected by the transaction recorded.” 59 A.L.R.2D 1299 § 25 (2013) (collecting cases).
. See e.g., Restatement (Third) of Property: Mortgages § 5.4 cmt. b (1997); 55 Am.Jur.2d Mortgages § 924 (2013); 3 Tex. Forms Legal & Bus. § 3:60 (2012). Admittedly, the Texas Local Government Code declares that the assignment of a recorded instrument must itself be recorded. See Tex. Local Gov’t Code § 192.007(a). However, this obscure provision has never been cited in a state court decision and is best read as a procedural directive to county clerks, not as a prerequisite to the validity of assignments. See Miller v. Homecomings Fin., LLC, 881 F.Supp.2d 825, 830 (S.D.Tex.2012) (noting that ”[t]he legal consequences of failing to comply with [§ 192.007(a)] are unclear”); KCB Equities, Inc. v. HSBC Bank USA, Nat’l Ass’n, 2012 WL 1985899, at *2 (Tex.Ct.App.2012) (unpublished) (rejecting argument that assignment of recorded mortgage must itself be recorded to be effective).

. In reality, of course, a PSA is executed to benefit the investors who buy securities backed by the mortgage pool-investors who would be harmed by enforcing the PSA to keep mortgages out of the pooling trust. Unsurprisingly, courts invariably deny mortgagors third-party status to enforce PSAs. See, e.g., In re Walker, 466 B.R. 271, 284-85 (Bankr.E.D.Pa.2012); Kelly v. Deutsche Bank Nat’l Trust Co., 789 F.Supp.2d 262, 267-68 (D.Mass.2011); Bittinger v. Wells Fargo Bank NA, 744 F.Supp.2d 619, 625-26 (S.D.Tex.2010).
. See also Martins v. BAC Home Loans Servicing, L.P., 722 F.3d 249, 255 (5th Cir.2013) (holding that in Texas "the party to foreclose need not possess the note itself” and that "the mortgage servicer need not hold or own the note and yet would be authorized to administer a foreclosure”).
. This, of course, does not require the owner and holder of the note to produce the actual original note at the time of foreclosure. Cf. Cadle Co., 21 S.W.3d at 674 (citing Commercial Serv. of Perry, Inc. v. Wooldridge, 968 S.W.2d 560, 564 (Tex.App.1998)) (“To collect on a promissory note, a plaintiff must establish: (1) the existence of the note in question, (2) the defendant signed the note, (3) the plaintiff is the owner and holder of the note, and (4) a certain balance is due and owing on the note.”).
