CROSSOVER: Austin Court: Post-Divorce Side Deal to Buy Ex-Spouse’s House Fails Against Divorce Decree and Merger Clause

Armstrong v. Thomas, 03-24-00433-CV, May 07, 2026.

On appeal from 455th District Court of Travis County

Synopsis

A post-divorce handwritten side agreement purporting to let one ex-spouse buy the other’s house did not survive where the parties’ agreement incident to divorce and final decree awarded the property to the title-holding spouse, included broad conveyancing language, and contained a merger clause. The Austin Court also reiterated the procedural point family-law litigators should already have in muscle memory: Findings of fact and conclusions of law have no proper role in a summary-judgment proceeding.

Relevance to Family Law

This is a family-law case in everything but label. It underscores that once an agreement incident to divorce and decree comprehensively allocate real property—and especially where the AID contains an integration or merger clause—later arguments based on contemporaneous side deals face substantial enforceability problems. For Texas family-law litigators, the opinion is a reminder that property settlements must capture every material deal in the divorce papers themselves, because post hoc efforts to characterize omitted understandings as separate contracts may fail both substantively and procedurally.

Case Summary

Fact Summary

Armstrong and Thomas were divorcing, and on December 20, 2013, they executed two separate writings. The first was an agreement incident to divorce. That AID provided that any real property in Thomas’s name would be confirmed as his separate property in the divorce. It also included a classic merger clause stating that it superseded all other oral or written agreements between the parties relating to rights and liabilities arising out of the marriage and that it contained the parties’ entire agreement. The subsequent final decree incorporated the AID and expressly provided that Armstrong “partitions, quitclaims, assigns and conveys” to Thomas any real property in his name.

The second writing, signed the same day, was a short handwritten agreement under which Armstrong contended she had the right to purchase the Knollwood property from Thomas. Armstrong further testified that Thomas orally agreed to prepare closing documents, and she paid him $40,000 shortly after the agreement was signed. After the divorce, Armstrong remained in the home with Thomas’s permission, paid for certain improvements, and over the years discussed closing with him, but no formal conveyance documents were ever executed.

The dispute ripened in 2023 when Thomas began serving notices to vacate. Armstrong sued in district court seeking to enforce the handwritten purchase agreement. Thomas answered and asserted counterclaims for trespass to try title, quiet title, and declaratory relief that the agreement was unenforceable. He then moved for traditional summary judgment on several grounds, including that the AID controlled, the handwritten agreement omitted essential terms required under the statute of frauds, and limitations had expired. After the summary-judgment hearing, Armstrong nonsuited her affirmative claims, but Thomas’s counterclaims remained pending. The trial court granted summary judgment for Thomas, declared the purchase agreement unenforceable, quieted title in his favor, and awarded attorney’s fees.

Issues Decided

• Whether the trial court erred by failing to issue findings of fact and conclusions of law in connection with a summary judgment and the denial of a motion for new trial.
• Whether summary judgment was improper because a genuine issue of material fact existed regarding enforceability of the handwritten real-estate purchase agreement.
• Whether the trial court could grant summary judgment on Thomas’s counterclaims after Armstrong nonsuited her own affirmative claims.

Rules Applied

The court applied several familiar rules with direct implications for post-divorce property litigation:

• Findings of fact and conclusions of law are generally improper in summary-judgment proceedings. The court cited Linwood v. NCNB Texas, 885 S.W.2d 102, 103 (Tex. 1994), and Gardner v. Abbott, 414 S.W.3d 369, 380 (Tex. App.—Austin 2013, no pet.).
• Traditional summary judgments are reviewed de novo, with the appellate court taking evidence favorable to the nonmovant as true and indulging reasonable inferences in the nonmovant’s favor. The court cited Weekley Homes, LLC v. Paniagua, 691 S.W.3d 911, 915 (Tex. 2024), Energen Resources Corp. v. Wallace, 642 S.W.3d 502, 509 (Tex. 2022), and Eagle Oil & Gas Co. v. TRO-X, L.P., 619 S.W.3d 699, 705 (Tex. 2021).
• A quiet-title plaintiff must establish a right of ownership and show that the opposing instrument or claim constitutes a cloud on title. The court relied on Faith P. & Charles L. Bybee Foundation v. Knutzen, 681 S.W.3d 818, 828–29 (Tex. App.—Austin 2023, no pet.), Brumley v. McDuff, 616 S.W.3d 826, 835 (Tex. 2021), and related authorities.
• Contracts for the sale of real property fall within the statute of frauds. See Tex. Bus. & Com. Code § 26.01(b)(4).
• To satisfy the statute of frauds, the writing must contain all essential terms with sufficient certainty so that the parties’ intent can be understood without resort to parol evidence. The court cited ConocoPhillips Co. v. Hahn, 704 S.W.3d 515, 533 (Tex. 2024), quoting Wilson v. Fisher, 188 S.W.2d 150, 152 (Tex. 1945).
• A nonsuit does not extinguish a pending defensive claim or counterclaim for affirmative relief; accordingly, the trial court retains authority to adjudicate surviving counterclaims.

Application

The Austin Court approached the case as a title-and-enforceability dispute, not as an invitation to reconstruct the parties’ unstated divorce-era expectations. Thomas produced summary-judgment evidence establishing his title chain, the AID, and the final decree. That evidence showed both that the property had been confirmed to him and that Armstrong had quitclaimed any interest she might have had. The handwritten agreement, if enforceable, would have clouded that title; so the question became whether Armstrong had raised a genuine issue that the instrument could legally support a purchase right.

The court took Armstrong’s affidavit into account, notwithstanding the trial judge’s later comments during the new-trial hearing minimizing its value. Even crediting her testimony, however, the affidavit did not save the deal. Her testimony largely established the existence of ongoing discussions, a $40,000 payment, continued occupancy, and Thomas’s alleged oral promises to prepare closing papers. But those facts merely highlighted the central problem: the parties never reduced the essential sale terms to an enforceable written agreement. Because a contract for the sale of real property must satisfy the statute of frauds, missing material terms cannot be supplied by oral testimony about what the parties supposedly intended or later discussed.

That was enough to affirm summary judgment on Thomas’s quiet-title and declaratory theories. Once the court concluded the handwritten purchase agreement was unenforceable for failure to satisfy the statute of frauds, the instrument necessarily functioned only as a cloud on Thomas’s title rather than a viable contractual right. The court therefore did not need to reach the other asserted grounds in depth, including the interplay between the merger clause and the side agreement or the limitations defense, because the absence of essential terms was dispositive.

The nonsuit point was equally straightforward. Armstrong’s nonsuit disposed of her own claims, but Thomas had pleaded independent counterclaims for affirmative relief. Those counterclaims survived and supported a final adjudication declaring the agreement unenforceable and quieting title in Thomas.

Holding

The court first held that the trial court did not err by declining to issue findings of fact and conclusions of law. As a threshold matter, Armstrong had not properly requested them, but more importantly, findings and conclusions are not appropriate vehicles in a summary-judgment proceeding at all. That point remains black-letter Texas procedure.

The court next held that summary judgment was proper because the handwritten agreement to purchase the property was unenforceable. Applying the statute of frauds, the court concluded that even when Armstrong’s affidavit was considered in the light most favorable to her, the alleged contract lacked essential terms necessary to enforce a real-estate sale. Because the purported agreement was unenforceable, Thomas was entitled to declaratory relief and to removal of the resulting cloud on his title.

Finally, the court held that Armstrong’s nonsuit of her own claims did not deprive the trial court of authority to enter summary judgment on Thomas’s pending counterclaims. Those claims sought independent affirmative relief and remained live after the nonsuit. The judgment was therefore properly entered and properly affirmed.

Practical Application

For family-law litigators, this opinion is a drafting and enforcement warning shot. If spouses intend to create a buyout option, installment sale, lease-purchase, reimbursement mechanism, occupancy right, deferred closing arrangement, or right of first refusal tied to the marital residence, the deal needs to be integrated into the AID, MSA, decree, or ancillary closing documents with the same rigor you would demand in a commercial real-estate transaction. A short handwritten memo and later oral assurances will not reliably overcome a decree that confirms title, includes quitclaim language, and purports to embody the entire agreement.

The case is also useful in post-divorce enforcement and defensive litigation. When a former spouse asserts a residual claim to real property based on some side understanding, this opinion supports an early merits attack through declaratory relief and quiet-title practice, particularly where the decree contains integration language and the alleged contract is incomplete. Conversely, if you represent the claimant, this case shows the danger of pleading equitable themes without a statute-of-frauds-compliant writing.

In trial-court practice, the opinion reinforces several tactical points:

• Do not request findings of fact and conclusions of law after summary judgment as though they are necessary to preserve error; they are not.
• If your opponent nonsuits, examine whether your client’s counterclaims for affirmative relief remain viable and should be reduced to judgment.
• In property disputes emerging from divorce decrees, attach the AID, decree, chain-of-title documents, and any conveyancing instruments early and frame the dispute as one about legal enforceability, not equitable disappointment.
• Where the alleged side agreement was contemporaneous with the divorce, scrutinize integration, merger, release, partition, and quitclaim language. Those provisions may significantly narrow the field before you ever reach credibility disputes.

Checklists

Drafting Divorce-Related Real Estate Transfers

• Put any buyout, option, lease-purchase, or deferred-sale arrangement in the AID, MSA, decree, or separate contemporaneous closing documents expressly referenced in those instruments.
• Include all material terms of the sale in writing, including property identification, price, payment structure, timing, financing terms if material, closing obligations, and remedies on default.
• State clearly whether the divorce documents supersede all prior or contemporaneous side agreements.
• Avoid broad merger clauses if the parties truly intend collateral agreements to survive; instead, expressly carve them out.
• If one spouse is receiving title only as an interim step before a later resale, say so expressly in the decree and define the mechanics.
• Coordinate decree language with deed language so there is no mismatch between the family-court order and title documents.

Litigating Against a Claimed Post-Divorce Side Deal

• Obtain and compare the AID, MSA, decree, deed records, and any alleged collateral agreement side by side.
• Identify merger, integration, release, partition, and quitclaim language.
• Analyze whether the alleged contract falls within the statute of frauds.
• Attack missing essential terms early in a traditional summary-judgment motion.
• Plead quiet title, trespass to try title where appropriate, and declaratory relief if the instrument clouds record title.
• Preserve attorney’s-fee theories where declaratory relief is properly invoked.
• Emphasize that parol evidence cannot supply essential terms missing from a real-estate contract.

Preserving and Proving the Claimant’s Position

• Secure a complete written agreement before decree entry if your client expects to acquire the property later.
• If a side agreement exists, make sure it identifies the property and contains all material terms without needing oral supplementation.
• Obtain signatures, dates, and any referenced attachments or amendments.
• Document consideration and performance with precision, but recognize that payment alone will not cure statute-of-frauds defects.
• Evaluate equitable theories separately, but do not confuse them with enforceability of a real-estate sales contract.
• If suit is necessary, plead around merger and integration language with specificity rather than broad equitable narratives.

Summary-Judgment Procedure in Family-Law Crossover Cases

• Do not rely on findings of fact and conclusions of law after summary judgment; they are improper.
• Build the appellate record through written objections, responses, evidence, and rulings in the summary-judgment papers.
• If the other side nonsuits, determine whether your client’s counterclaims remain pending and independently support judgment.
• Frame surviving claims as requests for affirmative relief to avoid being swept away by the nonsuit.
• On appeal, focus on whether the movant established entitlement to judgment as a matter of law on at least one ground.

Family Law Crossover

This opinion can be weaponized in divorce litigation whenever an opposing party tries to enforce an off-book understanding that is inconsistent with, or omitted from, the decree package. If you represent the spouse awarded title, use Armstrong to argue that the decree and AID are the operative universe of enforceable obligations, particularly where they include merger language and present-tense conveyancing terms. The case is equally useful in post-decree disputes involving alleged oral promises about refinancing, future conveyance, occupancy, or reimbursement tied to the marital residence.

In modification or enforcement settings, the broader strategic lesson is that Texas courts will not permit litigants to backdoor omitted divorce bargains through vague handwritten memoranda and years of informal conduct. That matters not only in property cases but in any family-law context where one side attempts to elevate side understandings over the signed order. Armstrong gives practitioners a disciplined way to reframe those disputes as enforceability problems governed by integration, title documents, and the statute of frauds—not as credibility contests about what the parties supposedly meant years earlier.
