A minor adjudged to have committed a delinquent act may be ordered by the Juvenile Court to reimburse the fund himself, either by a single payment or in installments, at the discretion of the Court. Interest shall be assessed against the minor at the legal rate from the date of disbursement from the fund. Unless the minor is an emancipated minor, the parents or guardian of a minor shall be ordered to cosign with the minor a note for the amount of the award to insure the fund is reimbursed. If this is ordered, the liability of the minor precedes the liability of the parents or guardian.
