Texas Finance Code - FIN § 123.105. Fees

(a) A credit union may collect a fee, determined by the board, for services and administrative costs, including a fee for a check or draft that is returned because it is drawn against a closed account or an account containing insufficient or uncollected money, because of a stop payment order, or for another similar reason.

(b) A fee under this section is an administrative expense. The fee is in addition to interest authorized by law and is not a part of interest collected or agreed to be paid on a loan.
