Texas Local Government Code - LOC GOV'T § 62.163. Action for Debt

(a) The holder of an indebtedness against a municipality to which Section 62.161 applies may bring a suit to establish the indebtedness in any court in this state with jurisdiction in the county in which the municipality is located. The court may render judgment in the suit against the municipality as fully as if the municipality had not been abolished or its organization declared void. The status of the municipality remains the same insofar as it affects the holders of its indebtedness until the indebtedness is paid.

(b) The municipality may be served with process in the suit by serving the citation on a person who was or who acted as the mayor, the secretary, or the treasurer of the municipality at the time of the municipality's abolition.
