Tex. Family Code § 157.167

(a) If the court finds that the respondent has failed to make child support payments, the court shall order the respondent to pay the movant's reasonable and necessary attorney's fees, court costs, and expenses in addition to the arrearages. Fees, costs, and expenses ordered under this subsection may be enforced by any means available for the enforcement of child support, including contempt. The court may order the fees, costs, expenses, and any postjudgment interest to be paid directly to the attorney, who may enforce the order in the attorney's own name by any means available for the enforcement of a judgment for debt.

(a-1) In rendering a judgment for attorney's fees and court costs under Subsection (a), the court shall render the judgment separate from any judgment confirming the amount of arrearages under Section 157.263.

(b) If the court finds that the respondent has failed to comply with the terms of an order providing for the possession of or access to a child, the court shall order the respondent to pay the movant's reasonable and necessary attorney's fees, court costs, and expenses in addition to any other remedy. If the court finds that the enforcement of the order with which the respondent failed to comply was necessary to ensure the child's physical or emotional health or welfare, the fees, costs, and expenses ordered under this subsection may be enforced by any means available for the enforcement of child support, including contempt, but not including income withholding.

(c) Except as provided by Subsections (d) and (e), for good cause shown, the court may waive the requirement that the respondent pay reasonable and necessary attorney's fees, costs, and expenses if the court states the reasons supporting that finding.

(d) If the court finds that the respondent is in contempt of court for failure or refusal to pay child support and that the respondent owes $20,000 or more in child support arrearages, the court may not waive the requirement that the respondent pay reasonable and necessary attorney's fees, costs, and expenses unless the court also finds that the respondent:

(1) is involuntarily unemployed or is disabled; and

(2) lacks the financial resources to pay the attorney's fees, costs, and expenses.

(e) The court may not waive the requirement that the respondent pay attorney's fees and costs if the court finds that the respondent has previously been found in contempt of court at least three times for the denial of court-ordered possession of or access to the child who is the subject of the proceeding.
