Mulford v. 1st Service Solutions, 06-25-00110-CV, July 15, 2026.
On appeal from 96th District Court, Tarrant County, Texas
Synopsis
Texas Rule of Civil Procedure 193.6 is a true exclusion rule, not a discretionary slap on the wrist. When a party fails to serve required initial disclosures, untimely files pretrial disclosures, and produces trial documents only days before trial, the evidence and nonparty witness testimony must be excluded unless the proponent carries the burden to prove good cause or the absence of unfair surprise or unfair prejudice. In Mulford, the proponent did not meet that burden, so exclusion was proper and the ruling effectively ended the case.
Relevance to Family Law
Family law litigators should read Mulford as a reminder that Rule 193.6 can decide a divorce, SAPCR, modification, or enforcement case before the merits are ever reached. The same disclosure architecture applies in family cases: damages models become reimbursement or economic contribution calculations, commercial documents become bank records and tracing exhibits, and witness lists become therapists, appraisers, business valuators, custody evaluators, and fact witnesses. If a party intends to prove separate property, reimbursement, hidden income, dissipation, conservatorship concerns, or fee shifting through documents or third-party testimony that were not timely disclosed, Mulford shows the trial court may be required to exclude that proof altogether.
Case Summary
Fact Summary
The plaintiff, a former senior vice president of sales, sued his former employer and two individuals for unpaid commissions, alleging he was owed more than $800,000. His pleading indicated the case proceeded under Level 2 discovery. The trial court had previously set the case for trial more than once, and the case was ultimately set for a bench trial on June 30, 2025.
The critical procedural facts drove the appeal. The plaintiff never served initial disclosures. Then, less than thirty days before trial, he filed proffered exhibit and witness lists. Shortly before trial, he filed an amended exhibit list adding additional exhibits and, according to the motion to strike, served nearly 180 pages of previously undisclosed documents fewer than three business days before trial. The defendants moved to strike the exhibits and witnesses on the ground that the materials had not been produced in discovery and the disclosures were untimely.
On the day of trial, the plaintiff responded that neither side had provided state disclosures and argued there was no unfair surprise or prejudice, but he did not articulate good cause for the failures. At the hearing, the trial court focused on the absence of mandatory Rule 194 disclosures and the late production of trial materials. The court found no good cause, granted the motion to strike the exhibits, observed that the plaintiff could not carry his burden of proof without the excluded evidence, and rendered judgment against him.
Issues Decided
- Whether Rule 193.6 required exclusion of evidence and witness testimony when the proponent failed to serve initial disclosures and did not timely provide pretrial disclosures.
- Whether documents produced only days before trial were properly excluded under Rule 193.6.
- Whether the proponent carried the burden to establish either good cause or lack of unfair surprise or unfair prejudice.
- Whether the trial court abused its discretion by excluding the evidence.
- Whether any complaint regarding continuance was preserved or waived.
Rules Applied
The court centered its analysis on Texas Rules of Civil Procedure 193.6, 194.1, 194.2, 194.4, 193.5, and 190.3, together with the applicable Tarrant County local rule requiring service of disclosures in accordance with the Rules of Civil Procedure.
Key rules and authorities included:
- Texas Rule of Civil Procedure 193.6: Untimely disclosed material or witness testimony may not be introduced unless the court finds good cause or lack of unfair surprise or unfair prejudice.
- Texas Rule of Civil Procedure 193.6(b): The burden rests on the party seeking to offer the evidence or witness.
- Texas Rule of Civil Procedure 194.1(a): Mandatory disclosures must be made without awaiting a discovery request.
- Texas Rule of Civil Procedure 194.2(b): Initial disclosures include legal theories, damages calculations, persons with knowledge, and documents or categories of documents the party may use to support claims or defenses.
- Texas Rule of Civil Procedure 194.4(a): Pretrial disclosures must identify witnesses and exhibits expected to be offered at trial.
- Texas Rule of Civil Procedure 193.5(b): A supplement made less than thirty days before trial is presumed not reasonably prompt.
- Texas Rule of Civil Procedure 190.3(b)(1)(A)(i): In Level 2 cases, discovery generally closes thirty days before trial.
- Cire v. Cummings, 134 S.W.3d 835 (Tex. 2004): Rule 193.6’s exclusion remedy is mandatory unless an exception is proven.
- Intermediate appellate authority cited by the court reinforced that Rule 193.6 exclusion is not reviewed as a death-penalty sanction because it is not a discretionary sanction under Rule 215; it is the mandatory consequence prescribed by Rule 193.6.
Application
The Texarkana court treated the dispute as a straightforward Rule 193.6 problem rather than a discretionary sanctions case. That framing matters. Once the record established that the plaintiff never served initial disclosures and attempted to rely on exhibits and witnesses disclosed late, including documents produced only days before trial, the burden shifted squarely to the plaintiff to establish one of Rule 193.6’s two escape valves: good cause or lack of unfair surprise or unfair prejudice.
The court’s reasoning reflects a disciplined procedural sequence. First, the missing initial disclosures were themselves a serious defect because Rule 194.1 and 194.2 require those disclosures without waiting for a request. Second, the pretrial witness and exhibit disclosures were untimely under the thirty-day framework governing Level 2 discovery and Rule 194.4. Third, the late-served documents were not saved by simply filing an exhibit list, especially where the opposing side represented that the materials had not been produced during discovery and were served fewer than three business days before trial. Fourth, the plaintiff’s response did not develop a record establishing either exception. The opinion notes that he did not address good cause in his written response, and at the hearing he effectively conceded that no good cause existed.
The absence of unfair surprise or prejudice also was not established on this record. The defendants argued they had no meaningful opportunity to examine the newly produced documents or question witnesses about them before trial. That is precisely the kind of trial-by-ambush concern Rule 193.6 is designed to prevent. Because the rule is mandatory absent a supported exception, the trial court did not need to fashion a lesser remedy. Exclusion followed, and once the plaintiff’s proof was struck, the inability to carry the burden of proof made judgment against him inevitable.
Holding
The court held that Rule 193.6 required exclusion of evidence and witness testimony not timely disclosed in discovery, including material that should have been included in mandatory initial disclosures and pretrial disclosures. Because the plaintiff never served initial disclosures and produced trial materials only days before trial, the trial court acted within its discretion in excluding the evidence.
The court also held that the burden to prove good cause or lack of unfair surprise or unfair prejudice rested on the proponent of the evidence, and that burden was not met. The record did not support an exception to Rule 193.6, particularly where the proponent did not show good cause and the opposing parties demonstrated the practical prejudice caused by last-minute production.
Finally, the court affirmed the judgment rendered after exclusion of the plaintiff’s evidence, concluding there was no abuse of discretion in the evidentiary ruling. It further concluded that the continuance complaint was waived.
Practical Application
For family law litigators, Mulford should recalibrate how you prepare for trial in document-heavy and witness-heavy cases. In a property division dispute, separate-property tracing schedules, QuickBooks exports, business records, appraisals, reimbursement calculations, and spreadsheets summarizing transfers are often the core proof. In custody litigation, the same risk attaches to school records, therapy records, medical records, photographs, social media captures, guardian materials, and testimony from counselors, teachers, relatives, and retained experts. In fee disputes and enforcement proceedings, billing records, payment histories, and communications may be outcome-determinative. If those items were not timely disclosed, Rule 193.6 provides the opponent with a potent exclusion objection.
Strategically, Mulford is useful from both sides of the docket. If you are defending against a late evidentiary dump before a temporary-orders hearing, final trial, or modification trial, the case reinforces that exclusion is not merely available; absent a proven exception, it is required. If you are the proponent, do not assume that naming a witness in a pleading, filing a pretrial exhibit list, or producing documents on the eve of trial will cure months of nondisclosure. It will not. The safest practice in family litigation is to build your trial proof through the disclosure rules from the beginning, supplement promptly, and create a record early if there is a genuine basis for good cause.
Several recurring family-law settings are especially exposed:
- Separate property and reimbursement claims often rise or fall on tracing documents and summary exhibits. Late production can eliminate the claim.
- Business valuation disputes depend on expert materials, financial records, and owner testimony. Untimely disclosure can cripple both valuation and cross-examination.
- Custody trials frequently rely on third-party witnesses such as teachers, therapists, and counselors. Those are exactly the kinds of witnesses Rule 193.6 can bar if not timely identified.
- Interim hearings that become de facto merits hearings create timing pressure. If the evidentiary file is not already properly disclosed, the case may be tried with one hand tied behind counsel’s back.
- Attorney’s fees claims require proof too. If billing records or fee opinions are disclosed late, fee recovery can be jeopardized.
Checklists
Disclosure Compliance Before Trial Settings
- Identify at case intake whether the matter is proceeding under Level 2 or a family-law scheduling order with custom deadlines.
- Calendar the initial disclosure deadline immediately.
- Serve Rule 194.2 disclosures even if the other side has not requested them.
- Include damages-type information tailored to family law issues, such as reimbursement calculations, arrearage computations, fee claims, and property characterization theories.
- Identify all persons with knowledge of relevant facts, including family members, accountants, therapists, teachers, appraisers, and business employees.
- Disclose or describe by category all documents you may use to support claims or defenses, unless solely for impeachment.
- Calendar the pretrial disclosure deadline at least thirty days before trial, absent a different court order.
- Confirm compliance with county local rules in addition to the statewide rules.
Trial Exhibit Management
- Build the exhibit list from documents already disclosed in written discovery or mandatory disclosures.
- Audit every planned exhibit against prior production before filing pretrial disclosures.
- Flag summaries, demonstratives, and compilations that depend on underlying records and ensure both are disclosed.
- Do not assume that filing an exhibit list substitutes for producing the documents themselves.
- Avoid last-minute supplementation unless absolutely necessary and defensible.
- If supplementation occurs within thirty days of trial, prepare to overcome the presumption that it was not reasonably prompt.
Witness Disclosure Control
- Distinguish party witnesses from nonparty witnesses, but do not assume that solves every disclosure problem.
- Timely identify fact witnesses with a brief statement of their connection to the case.
- Timely designate and disclose retained experts under the applicable expert deadlines.
- Update witness information as soon as additional witnesses become reasonably anticipated.
- Match each witness to the issue they support so you can assess whether exclusion would be fatal.
- Before trial, confirm that every witness expected to testify appears in your disclosures and pretrial witness list.
Preserving a Rule 193.6 Exception
- If evidence was not timely disclosed, prepare a focused record on good cause and on lack of unfair surprise or unfair prejudice.
- Support the exception with testimony, affidavits, stipulations, or detailed proffers as appropriate.
- Explain specifically why the late disclosure occurred and why it could not reasonably have been avoided.
- Show specifically why the opponent is not unfairly surprised or prejudiced, such as prior possession of the same records, prior deposition testimony about them, or earlier production from another source.
- Request a ruling expressly addressing the Rule 193.6 exception.
- If exclusion would be case-dispositive, make a full offer of proof to preserve appellate complaint.
Using Mulford as the Objecting Party
- Compare the opponent’s pretrial disclosures to prior discovery responses and productions.
- Move to strike exhibits and nonparty witnesses that were never disclosed or were disclosed untimely.
- Emphasize the mandatory language of Rule 193.6 and the burden allocation under subsection (b).
- Frame the prejudice concretely: inability to depose, inability to test authenticity, inability to retain rebuttal experts, inability to prepare cross-examination.
- Distinguish Rule 193.6 exclusion from discretionary sanctions analysis.
- Ask the court for an express ruling before evidence is offered at trial.
Protecting Core Family-Law Claims from Exclusion
- For separate-property tracing, disclose bank records, deeds, entity records, spreadsheets, and tracing summaries early.
- For reimbursement or waste claims, disclose the accounting methodology and supporting financial records.
- For custody issues, timely disclose school, medical, counseling, and law-enforcement records you may rely on, subject to privilege and protective-order practice.
- For fee claims, disclose billing records, fee opinions, and any summary charts.
- For business-value disputes, disclose financial statements, tax returns, general ledgers, and expert materials on schedule.
- Reassess disclosure completeness each time the trial setting changes.
Family Law Crossover
The procedural mechanism in Mulford is the mandatory exclusion feature of Rule 193.6, triggered by a failure to timely make, amend, or supplement discovery responses, including required Rule 194 disclosures. In a Texas family law case, that mechanism arises when a party attempts to offer at final trial, temporary orders, modification, enforcement, or a property-division retrial documents or nonparty testimony that were not timely disclosed. The trial court’s task is not to evaluate general fairness in the abstract; it is to determine whether the proponent has carried the burden to prove good cause or the absence of unfair surprise or unfair prejudice, with a record supporting that finding. If that showing is not made, exclusion is mandatory. In family cases, that can directly affect tracing exhibits, valuation materials, reimbursement calculations, therapist or teacher testimony, social media evidence, banking records, and fee proof.
