Tex. Local Government Code § 134.156

(a) In a county or municipality that employs or contracts with a juvenile case manager under Article 45A.451, Code of Criminal Procedure, money allocated under Section 134.103 to the local youth diversion fund maintained in the county or municipal treasury as required by Section 134.151 may be used by a county or municipality to finance the salary, benefits, training, travel expenses, office supplies, and other necessary expenses relating to the position of a juvenile case manager. If there is money in the fund after those costs are paid, subject to the direction of the governing body of the county or municipality and on approval by the employing court, a juvenile case manager may direct the remaining money to be used to implement programs directly related to the duties of the juvenile case manager, including juvenile alcohol and substance abuse programs, educational and leadership programs, and any other projects designed to prevent or reduce the number of juvenile referrals to the court.

(a-1) In a county or municipality that does not employ or contract with a juvenile case manager, the governing body of the county or municipality, in consultation with the court, may direct money described by Subsection (a) to be used for the support of a local mental health authority, juvenile alcohol and substance abuse programs, educational and leadership programs, teen court programs, and any other project designed to prevent or reduce the number of juvenile referrals to the court.

(b) Money in the fund may not be used to supplement the income of an employee whose primary role is not that of a juvenile case manager.
