Tex. Code of Criminal Procedure § 2A

(a) The state shall reimburse a county for compensation of counsel under Section 2, other than for compensation of counsel employed by the office of capital and forensic writs, and for payment of expenses under Section 3, regardless of whether counsel is employed by the office of capital and forensic writs. The total amount of reimbursement to which a county is entitled under this section for an application under this article may not exceed $25,000. Compensation and expenses in excess of the $25,000 reimbursement provided by the state are the obligation of the county.

(b) A convicting court seeking reimbursement for a county shall certify to the comptroller of public accounts the amount of compensation that the county is entitled to receive under this section. The comptroller of public accounts shall issue a warrant to the county in the amount certified by the convicting court, not to exceed $25,000.

(c) The limitation imposed by this section on the reimbursement by the state to a county for compensation of counsel and payment of reasonable expenses does not prohibit a county from compensating counsel and reimbursing expenses in an amount that is in excess of the amount the county receives from the state as reimbursement, and a county is specifically granted discretion by this subsection to make payments in excess of the state reimbursement.

(d) The comptroller shall reimburse a county for the compensation and payment of expenses of an attorney appointed by the court of criminal appeals under prior law. A convicting court seeking reimbursement for a county as permitted by this subsection shall certify the amount the county is entitled to receive under this subsection for an application filed under this article, not to exceed a total amount of $25,000.
