Cal. CCP § 708.180

(a) Subject to subdivision (b), if a third person examined pursuant to Section 708.120 claims an interest in the property adverse to the judgment debtor or denies the debt, the court may, if the judgment creditor so requests, determine the interests in the property or the existence of the debt. The determination is conclusive as to the parties to the proceeding and the third person, but an appeal may be taken from the determination. The court may grant a continuance for a reasonable time for discovery proceedings, the production of evidence, or other preparation for the hearing.

(b) The court may not make the determination provided in subdivision (a) if the third person’s claim is made in good faith and any of the following conditions is satisfied:

(1) The court would not be a proper court for the trial of an independent civil action (including a creditor’s suit) for the determination of the interests in the property or the existence of the debt, and the third person objects to the determination of the matter under subdivision (a).

(2) At the time an order for examination pursuant to Section 708.120 is served on the third person a civil action (including a creditor’s suit) is pending with respect to the interests in the property or the existence of the debt.

(3) The court determines that the interests in the property or the existence of the debt should be determined in a creditor’s suit.

(c) Upon application of the judgment creditor made ex parte, the court may make an order forbidding transfer of the property to the judgment debtor or payment of the debt to the judgment debtor until the interests in the property or the existence of the debt is determined pursuant to subdivision (a) or until a creditor’s suit may be commenced and an order obtained pursuant to Section 708.240. An undertaking may be required in the discretion of the court. The court may modify or vacate the order at any time with or without a hearing on such terms as are just.

(d) Upon application of the judgment creditor upon noticed motion, the court may, if it determines that the judgment debtor probably owns an interest in the property or that the debt probably is owed to the judgment debtor, make an order forbidding the transfer or other disposition of the property to any person or forbidding payment of the debt until the interests in the property or the existence of the debt is determined pursuant to subdivision (a) or until a creditor’s suit may be commenced and an order obtained pursuant to Section 708.240. The court shall require the judgment creditor to furnish an undertaking as provided in Section 529. The court may modify or vacate the order at any time after notice and hearing on such terms as are just.
