Tex. R. Civ. P. 510.12 (2026)

(a) Amending Pleadings. A party may withdraw something from or add something to a pleading before trial.

(b) Insufficient Pleadings. A party may file a motion with the court asking that another party be required to clarify a pleading. The court must determine if the pleading is sufficient to place all parties on notice of the issues in the lawsuit, and may hold a hearing to make that determination. If the court determines a pleading is insufficient, the court must order the party to amend the pleading and set a date by which the party must amend. If a party fails to comply with the court’s order, the pleading may be stricken. A pleading amendment must not delay the trial date.
