CROSSOVER: Dallas COA: Denial of Continuance Before Summary Judgment—Reversal for Blocking Basic Discovery (Use in High‑Asset Divorce & Property Disputes)

Mosser v. Flagstar Bank, FSB; Select Portfolio Servicing Inc.; First Guaranty Mortgage Corporation; Federal Home Loan Mortgage Corporation, 05-23-01140-CV, March 30, 2026.

On appeal from 471st Judicial District Court, Collin County, Texas

Synopsis

The Dallas Court of Appeals reversed summary judgment because the trial court denied a continuance that the borrower supported with a proper request for time to conduct basic discovery necessary to respond to dispositive motions. Even in an older case, cutting off foundational discovery—especially where parties were added later and procedural events limited meaningful discovery time—can be an abuse of discretion under Rule 166a(g) and the continuance cases.

Relevance to Family Law

High-asset divorces routinely feature parallel “civil” disputes embedded inside the property case: title and lien challenges, refinancing/HELOC issues under Texas Constitution article XVI, § 50(a)(6), disputed assignments/servicing, and foreclosure pressure timed to coincide with temporary orders or trial settings. Mosser is a clean appellate lever for family-law litigators: when the other side tries to win the property war through an early no-evidence/traditional summary judgment—while resisting core discovery—this opinion supports reversal if the record shows the continuance was properly presented, targeted, and necessary to oppose summary judgment.

Case Summary

Fact Summary

The case arises from a Texas homestead lending/foreclosure dispute. The homeowner (Mosser) refinanced his homestead multiple times, including a “cash-out” home-equity transaction governed by Texas Constitution article XVI, § 50(a)(6). He alleged the later transaction failed to comply with constitutional requirements, rendering the lien invalid/void, and he provided notice to cure alleged defects.

As the dispute matured, multiple entities appeared in the chain—originator/lender, bank, servicer (SPS), and Freddie Mac. The defendants pursued summary judgment. Mosser sought a continuance of the summary-judgment hearings to conduct what the opinion characterizes as basic discovery needed to respond to the dispositive motions. The trial court denied the continuance and granted summary judgment for the defendants, awarding the relief they requested.

After submission on appeal, Mosser raised a jurisdictional challenge tied to a “corrective” assignment recorded later—arguing the assignment/standing defects undermined jurisdiction. The court of appeals addressed jurisdiction first, then reached the continuance issue, which became dispositive on this record.

Issues Decided

• Whether the court of appeals had appellate jurisdiction in light of Mosser’s post-submission challenge to a corrective assignment and alleged standing defects.
• Whether the trial court abused its discretion by denying Mosser’s motion for continuance to permit basic discovery before ruling on the summary-judgment motions.

Rules Applied

• Continuance in the summary-judgment context:
  • TEX. R. CIV. P. 166a(g) (continuance when the nonmovant cannot, for stated reasons, present essential facts to oppose summary judgment).
  • A verified motion for continuance may substitute for an affidavit. Ford Motor Co. v. Castillo, 279 S.W.3d 656 (Tex. 2009).
  • Conclusory continuance requests are insufficient. Assoun v. Gustafson, 493 S.W.3d 156 (Tex. App.—Dallas 2016, pet. denied).
  • Standard of review: abuse of discretion. Baleares Link Exp., S.L. v. GE Engine Servs.-Dallas, LP, 335 S.W.3d 833 (Tex. App.—Dallas 2011, no pet.).
  • Nonexclusive factors: time on file, materiality/purpose of discovery, and due diligence. Johnston v. Kruse, 261 S.W.3d 895 (Tex. App.—Dallas 2008, no pet.).
• Jurisdiction/standing framing:
  • Standing is a component of subject-matter jurisdiction. Heckman v. Williamson Cnty., 369 S.W.3d 137 (Tex. 2012).
  • Appellate courts must ensure subject-matter jurisdiction. S.C. v. M.B., 650 S.W.3d 428 (Tex. 2022).

Application

The court treated the continuance ruling as the critical gatekeeping error. It began with black-letter Rule 166a(g): when a nonmovant shows—by affidavit or verified motion—that it cannot yet present facts essential to justify its opposition, the trial court may continue the summary-judgment hearing to allow discovery. The opinion then walked through the familiar continuance factors.

On elapsed time, the court acknowledged the case had been on file for years, a fact that typically weighs against a continuance. But the court credited the reality that “time on file” is not a stopwatch. Discovery opportunity can be functionally reduced by procedural events (including stays/abatements) and by later joinder of parties, which changes what discovery is necessary and when it becomes possible. The court cited authority recognizing that stayed/abated time is not counted the same way and that courts evaluate discovery time as to particular defendants when they are joined later.

Most importantly for litigators, the court accepted that Mosser’s requested discovery was not a fishing expedition; it was “basic discovery” tied to the ability to meet and answer summary-judgment proof. When a party is asked to lose the case on paper—before it has had a fair chance to obtain foundational documents and testimony that bear directly on the movant’s entitlement to judgment—denying a properly supported continuance can become “arbitrary and unreasonable” in the Rule 166a(g) sense.

On the post-submission jurisdictional attack, the court held it retained jurisdiction and proceeded to the merits. Even assuming some standing dispute existed as to SPS, the court concluded that did not deprive it of jurisdiction to resolve the appeal as presented; it also signaled that standing/assignment disputes could still be addressed on remand.

Holding

The court held it had appellate jurisdiction notwithstanding Mosser’s post-submission challenge tied to a corrective assignment and alleged standing defects. The court proceeded to the merits rather than dismissing, and it left room for the trial court to address any standing/assignment disputes after remand.

Separately and dispositively, the court held the trial court abused its discretion by denying Mosser’s motion for continuance where the requested continuance was needed to conduct basic discovery essential to opposing the pending summary-judgment motions. Because the denial of discovery foreclosed a fair opportunity to respond on the merits, the court reversed the summary-judgment rulings and remanded for further proceedings.

Practical Application

For Texas family-law litigators, Mosser is a strategic citation when the property case is being decided through accelerated dispositive motion practice—especially in high-net-worth divorces where one side controls information (entity records, loan files, trust documents, valuation inputs, transactional communications) and tries to force a merits ruling before discovery is meaningfully available.

Common family-law applications:

• Homestead and lien combat inside divorce: One spouse claims a refinance/HELOC/home-equity lien is constitutionally defective; the lender/servicer (or the spouse aligned with them) pushes for early summary judgment. Mosser supports the proposition that the trial court must allow enough discovery to test the lien’s enforceability and the movant’s proof.
• Entity-heavy marital estates: When a spouse moves for summary judgment on characterization (separate vs. community), reimbursement, or fraud-on-the-community defenses while withholding entity financials, K-1s, general ledgers, and third-party deal documents, a Rule 166a(g) continuance can be framed as “basic discovery,” not delay.
• Third-party practice and late-added parties: When receivers, business entities, trustees, lenders, or employers are joined later, Mosser helps argue the “time on file” factor should be evaluated realistically as to those parties and the discovery they uniquely possess.
• Temporary orders leverage: If a party times summary judgment to coincide with a temporary-orders posture (support, exclusive use, injunctions) to create settlement coercion, Mosser reinforces that a discovery-blocking procedural win is vulnerable on appeal.

Checklists

Building a Rule 166a(g) Continuance Record (Summary Judgment)

• File a verified motion for continuance or an affidavit that tracks Rule 166a(g).
• Identify the specific discovery needed (categories of documents, depositions, third-party subpoenas) and tie each item to a summary-judgment element.
• Explain why the evidence is unavailable without discovery (exclusive control, third-party possession, authentication needs).
• Establish materiality: show how the discovery will create a fact issue or defeat an element of the movant’s claim/defense.
• Prove diligence with dates and exhibits: written discovery served, deposition notices, motions to compel, conferral letters, and hearing settings.
• Request a date-certain continuance and propose a practical discovery schedule to neutralize “delay” arguments.

Discovery Priorities in High-Asset Divorce Property Disputes (to Support Continuance)

• Chain-of-title and lien file: note, deed of trust, assignments, allonges, servicing agreements (as applicable), payoff histories.
• Closing file: settlement statement, § 50(a)(6) compliance documents, cure correspondence, lender communications.
• Entity documents: governing documents, cap tables, bank statements, general ledgers, tax returns, K-1s, loan covenants.
• Valuation inputs: appraisals, management forecasts, customer contracts, roll-forwards, post-valuation events communications.
• Authentication plan: custodian depositions/notices and business-record affidavits needed to contest admissibility.

Avoiding the Appellate Trap (If You’re the Summary-Judgment Movant)

• Do not oppose a reasonable, targeted continuance if your own proof depends on documents the other side cannot access.
• If you resist continuance, build a record showing the nonmovant had a fair discovery window and failed to act diligently.
• Offer limited production or stipulations that cure the claimed discovery need, and document the offer.
• Ensure your summary-judgment evidence is cleanly admissible; do not rely on “we’ll authenticate later” when discovery is being contested.

Family Law Crossover

In divorce and custody litigation, the “weapon” is not the foreclosure fact pattern—it’s the procedural principle: a party cannot be marched to a dispositive merits ruling while being denied the minimum discovery needed to respond. Use Mosser to (1) force a continuance when the other side files early summary judgment on characterization, reimbursement, wasting/fraud claims, or lien validity; (2) frame the requested discovery as foundational and element-driven rather than expansive; and (3) preserve reversible error by making a verified, nonconclusory record that the discovery sought is essential to controvert the motion. On remand leverage, the opinion also helps in cases involving late-recorded “corrective” instruments or chain-of-title maneuvering: even where jurisdiction is ultimately secure, appellate courts are receptive to arguments that the merits cannot be fairly adjudicated until basic discovery exposes what actually happened in the transaction file and the entity records.
