COA01 — February 12, 2026
In a Suit Affecting the Parent-Child Relationship (SAPCR), Relator Diego Raoul Goding filed a petition for writ of mandamus seeking to vacate three trial court orders. The First Court of Appeals denied the petition without reaching the merits of the case. The court's analysis focused on the Relator's failure to satisfy the mandatory procedural requirements under Texas Rules of Appellate Procedure 52.3 and 52.7, which require a relator to provide a sworn or certified record and a sufficient appendix. Because the Relator failed to authenticate the documents and provide a proper record of the underlying proceedings, the court held that he failed to demonstrate a clear entitlement to mandamus relief.
Litigation Takeaway
“Procedural technicalities in mandamus proceedings are mandatory and strictly enforced. Family law practitioners must ensure that every document in the appellate record is properly authenticated (either certified or sworn) and that the appendix complies with all requirements of TRAP 52; otherwise, the court will deny relief regardless of the underlying 'best interest of the child' arguments.”
