This question has been addressed in 1 Texas court opinion:
COA09 — January 28, 2026
In this case, Kenneth Chambless sought a writ of mandamus to compel a trial court to rule on motions he filed personally (pro se) while still being represented by an attorney. The Ninth Court of Appeals denied the request, reaffirming the long-standing Texas rule against 'hybrid representation.' The court analyzed the conflict under the standards for mandamus relief, concluding that because a trial court has no legal obligation or ministerial duty to address filings made by a party who has counsel of record, the judge has absolute discretion to ignore them. The holding confirms that a litigant must choose between representing themselves or being represented by a lawyer; they cannot do both simultaneously.
Litigation Takeaway
“Texas law does not permit 'hybrid representation.' Once you are represented by an attorney, the court is entitled to ignore any motions or documents you file on your own. This ensures that the attorney remains the sole 'commander of the ship' and prevents high-conflict litigants from clogging the court system with unauthorized or conflicting filings.”
