Why do Texas courts dismiss or deny mandamus petitions in family law cases?
This question has been addressed in 2 Texas court opinions:
In Re Darren L. Reagan
COA05 — February 5, 2026
Darren L. Reagan filed a petition for writ of mandamus seeking to vacate a trial court's order granting a Rule 91a motion to dismiss. The Dallas Court of Appeals denied the petition without reaching the substantive legal merits because the relator failed to comply with the technical requirements of the Texas Rules of Appellate Procedure. Specifically, the court analyzed the petition's failure to use the verbatim certification language now required by the renumbered Rule 52.3(k) and the failure to provide a sworn or certified record under Rule 52.7(a). The court held that strict adherence to the "exact words" of the appellate rules is a mandatory prerequisite for the court to exercise its jurisdiction for extraordinary relief.
Litigation Takeaway
“Technicalities can defeat even the strongest legal arguments. In the Dallas Court of Appeals, a mandamus petition will be summarily denied if the certification does not match the 2026 version of Rule 52.3(k) word-for-word or if the supporting record is not properly authenticated. Always perform a 'procedural audit' to ensure compliance with the latest appellate rule numbering and verbatim requirements.”
In Re Marcus Tyrone Grant
COA14 — January 27, 2026
In this proceeding, Relator Marcus Tyrone Grant sought a writ of mandamus to compel the Waller County Clerk to perform specific ministerial actions. The Fourteenth Court of Appeals analyzed its own subject-matter jurisdiction under Texas Government Code § 22.221, which lists the specific judicial officers subject to the court's original jurisdiction. The court observed that county clerks are not included in this statutory list. While the court has 'ancillary' jurisdiction to issue writs necessary to protect its own appellate power, the Relator failed to demonstrate that the clerk’s inaction interfered with a pending appeal. Consequently, the court held it lacked jurisdiction and dismissed the petition.
Litigation Takeaway
“When a court clerk refuses to perform a duty, such as issuing a citation or filing a record, you generally cannot seek immediate relief from the Court of Appeals. Unless the clerk's failure to act is actively blocking an ongoing appeal, the proper route is to file a mandamus petition against the clerk in a District Court. Filing in the wrong forum results in dismissal for lack of jurisdiction, wasting both time and legal fees.”
