ยง 5043. Posting and maintaining security. (a) If the court enters a judgment for periodic installments, each party liable for all or a portion of such judgment shall separately or jointly with one or more others post security in an amount necessary to secure payment for the amount of the judgment for future periodic installments within thirty days after the date the judgment is entered. A liability insurer having a contractual obligation and any other person adjudged to have an obligation to pay all or part of a judgment for periodic installments on behalf of a judgment debtor is obligated to post security to the extent of its contractual or adjudged obligation if the judgment debtor has not done so. (b) A judgment creditor or successor in interest and any party having rights may move that the court find that security has not been posted and maintained with regard to a judgment obligation owing to the moving party. Upon so finding, the court shall order that security complying with this article be posted within thirty days. If security is not posted within that time and subdivision (c) of this section does not apply, the court shall enter a judgment for the lump sum as such sum is determinable under the law without regard to this article. (c) If a judgment debtor who is the only person liable for a portion of a judgment for periodic installments fails to post and maintain security, the right to lump sum payment described in subdivision (b) of this section applies only against that judgment debtor and the portion of judgment so owed. (d) If more than one party is liable for all or a portion of a judgment requiring security under this article and the required security is posted by one or more but fewer than all of the parties liable, the security requirements are satisfied and those posting security may proceed under subdivision (b) of this section to enforce rights for security or lump sum payment to satisfy or protect rights of reimbursement from a party not posting security.
