Tex. Property Code § 41.023

(a) If a judgment debtor who has not made a voluntary designation of a homestead under Section 41.005 does not designate a homestead as provided in Section 41.022, on motion of the judgment creditor, filed within 90 days after the issuance of the writ of execution, the court from which the writ of execution issued shall appoint a commissioner to designate the judgment debtor's homestead. The court may appoint a surveyor and others as may be necessary to assist the commissioner. The commissioner shall file his designation of the judgment debtor's homestead in a written report, together with a plat of the area designated, with the justice or clerk of the court not more than 60 days after the order of appointment is signed or within such time as the court may allow.

(b) Within 10 days after the commissioner's report is filed, the judgment debtor or the judgment creditor may request a hearing on the issue of whether the report should be confirmed, rejected, or modified as may be deemed appropriate in the particular circumstances of the case. The commissioner's report may be contradicted by evidence from either party, when exceptions to it or any item thereof have been filed before the hearing, but not otherwise. After the hearing, or if there is no hearing requested, the court shall designate the homestead as deemed appropriate and order sale of the excess.

(c) The commissioner, a surveyor, and others appointed to assist the commissioner are entitled to such fees and expenses as are deemed reasonable by the court. The court shall tax these fees and expenses against the judgment debtor as part of the costs of execution.
