What are the requirements to contest a will in Texas probate court?
This question has been addressed in 3 Texas court opinions:
In the Matter of the Estate of Henry Matthew Platt
COA09 — January 29, 2026
In a dispute over the validity of a holographic will, the sister of the decedent attempted to disqualify the will through expert handwriting testimony. However, the expert's comparison samples (exemplars) did not consist of the decedent's own signature, but rather signatures the decedent allegedly made on behalf of his parents. The trial court excluded the expert's testimony, and the Ninth Court of Appeals affirmed. The court analyzed the case under Texas Rules of Evidence 703 and 705, concluding that because the expert lacked a 'control' sample of the decedent's actual name and signature, there was an unreliable foundation and an 'analytical gap' that rendered the opinion inadmissible.
Litigation Takeaway
“Expert testimony is only as reliable as the data supporting it; if your handwriting expert relies on representative or third-party signatures rather than authenticated personal signatures, the testimony is likely to be excluded for lack of foundation.”
Estate of Lake Zack Hughes v. Thoyze Baker Hughes
COA05 — February 6, 2026
In Estate of Lake Zack Hughes, a contestant challenged his alleged father's will, asserting he was an omitted biological son and claiming the will was a forgery. The trial court dismissed the contest and admitted the will to probate after the contestant failed to post a court-ordered security for costs and submitted a handwriting expert report that was not properly verified. On appeal, the Dallas Court of Appeals affirmed the judgment, holding that the trial court properly exercised its discretion in enforcing the Texas Estates Code's security requirements and the Rules of Evidence regarding unverified expert reports. The case underscores that a party's failure to bridge the gap between allegations and admissible evidence can lead to a final judgment without a trial.
Litigation Takeaway
“Procedural and evidentiary compliance is non-negotiable in inheritance and paternity litigation; failure to post court-ordered security or to verify expert reports with specific "penalty of perjury" language can result in the immediate dismissal of your claims.”
In the Estate of J. Hugh Wheatfall, Deceased
SCOTX — February 13, 2026
In a dispute over a decedent's estate, a trial court admitted a will to probate but explicitly limited its ruling to objections filed before a specific date, effectively ignoring a pending will contest filed just one day after that cutoff. The Supreme Court of Texas analyzed the case under the Crowson test, which determines finality in probate proceedings by whether an order unequivocally disposes of all parties and issues within a discrete phase of the litigation. The Court held that because the order's express language carved out a specific timeframe that excluded the pending contest, the order remained interlocutory, meaning the appellate timetable had not yet begun to run.
Litigation Takeaway
“To avoid the 'finality trap,' practitioners must verify that an order unequivocally disposes of all pending pleadings within a specific phase of litigation; if the order contains limiting language or fails to address a live contest, it may be interlocutory, preserving the right to appeal even after the standard 30-day window.”
