(735 ILCS 5/2-1711) (from Ch. 110, par. 2-1711)
    Sec. 2-1711. Posting and maintaining security. (a) If the court enters a judgment for period installments, each party liable for all or a portion of the judgment, unless found to be incapable of doing so under subsection (10) of Section 2-1708, shall separately or jointly with one or more others post security in an amount equal to the equivalent lump sum value of the unpaid judgment, including past damages, in a form prescribed in Section 2-1710, within 30 days after the date the judgment is subject to enforcement. 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 under subsection (d) 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 Section be posted within 30 days. If the security is not posted within that time, the court shall calculate the equivalent lump sum value of the obligation and enter a judgment for that amount in favor of the moving party.
    (c) If a judgment debtor who is the only person liable for all or a portion of a judgment requiring security under this Section fails to post and maintain security, the right to lump sum payment described in subsection (b) applies only against that judgment debtor and the portion of the judgment so owed.
    (d) If more than one party is liable for all or a portion of a judgment requiring security 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 subsection (b) to enforce rights for security or lump sum payment to satisfy or protect rights of reimbursement from a party not posting security.
