A. When the court suspends the imposition or execution of sentence and places the child or his parent or both on supervised probation or grants the child supervised parole, and the probationer or parolee is to be supervised by the Department of Public Safety and Corrections or any other agency, the court shall order payment, as a condition of probation or parole, of a monthly supervision fee. The supervision fee imposed shall not exceed fifty dollars per month and shall be payable to the department or other supervising agency to defray the costs of supervision. These funds are only to supplement the level of funds that would ordinarily be available from regular state or other appropriations.B. The parent is responsible for payment of any supervision fee imposed and is subject to contempt of court for failure to pay such fees. The parent shall not be subject to judicial sanctions for failure to pay supervision fees if the failure was due to financial inability to pay based upon reasonable expenses for the necessities of life.
