Texas Water Code - WATER § 56.308. Rejection of Claim

(a) If the trustee finds any claim unjust either in whole or in part, he shall endorse on the claim his refusal to allow it.

(b) If the whole claim is refused, the claimant may bring suit to collect the claim against the trustee in a court of competent jurisdiction in the county, and if the claim is judged valid by the court, the judgment shall be filed with the trustee and paid in its order as other claims.

(c) If the claim is refused only in part and the claimant waives his claim to the part refused, he shall file the claim in the commissioners court for approval, but if the claimant does not waive his claim to the part refused, he shall withdraw his claim from the trustee and may bring suit as provided in Subsection (b) of this section.
