Tex. Water Code § 7.063

If the executive director receives a copy of an affidavit under Section 7.062(2), the executive director may file with the court, within five days after the date the copy is received, a contest to the affidavit. The court shall hold a hearing on the facts alleged in the affidavit as soon as practicable and shall stay the enforcement of the penalty on finding that the alleged facts are true. The person who files an affidavit has the burden of proving that the person is financially unable to pay the penalty or give the supersedeas bond.
