(a) An installment payment by a criminal defendant to a circuit court shall initially be deemed to be a collection of court costs until the court costs have been collected in full, with any remaining installment payments representing collections of restitution, and then any applicable fines.
(b) If court costs, restitution, and fines are fully paid, all remaining installment payments shall be allocated to remaining amounts due as ordered by the circuit court.
(c) A municipal or county governing body that adopted municipal or county legislation before January 1, 2017, to provide an alternative method of installment payment allocation as then authorized by state law shall remain in effect until repealed by the municipal or county governing body.
