Conditions for Installment Payment

16380.  The trial court may order the payment of a judgment in installments only when the defendant is not insured or the insurance policy covering the automobile involved in the accident, for the ownership or operation of which the defendant is held liable, is not sufficient to pay the amount of the judgment, and then only as to such portion of the judgment not covered by the insurance policy. The order shall fix the amounts and times of payment of the installments and shall be without prejudice to any other legal remedies available to the judgment creditor.
