This question has been addressed in 1 Texas court opinion:
COA14 — February 5, 2026
In a divorce proceeding involving complex property characterization, the Husband designated an expert for tracing and valuation but failed to provide the actual tracing reports until six days before trial. The trial court excluded the late-disclosed tracing testimony while permitting testimony on the timely-disclosed valuation. On appeal, the Husband argued the exclusion constituted an improper 'death-penalty' sanction. The Fourteenth Court of Appeals affirmed the trial court's ruling, clarifying that the exclusion was a mandatory application of Texas Rule of Civil Procedure 193.6. The court held that because the ruling did not preclude the Husband's entire defense or claim, it did not rise to the level of a death-penalty sanction and was a proper exercise of discretion due to the lack of good cause or showing of non-prejudice.
Litigation Takeaway
“Discovery deadlines are strictly enforced for expert reports in property disputes; a trial continuance does not automatically reset these deadlines. Practitioners should never use 'to be provided' as a placeholder in expert designations and must produce the substance of tracing opinions within the discovery period to avoid the 'automatic' exclusion of evidence under Rule 193.6.”
