Tex. R. Civ. P. 502.7

As amended through November 19, 2024
Rule 502.7 - Amending and Clarifying Pleadings
(a)Amending Pleadings. A party may withdraw something from or add something to a pleading, as long as the amended pleading is filed and served as provided by Rule 501.4 not less than 7 days before trial. The court may allow a pleading to be amended less than 7 days before trial if the amendment will not operate as a surprise to the opposing party.
(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.
