CCP § 1268.130

At any time after the plaintiff has made a deposit upon the award pursuant to Section 1268.110, the court may, upon motion of any defendant, order the plaintiff to deposit such additional amount as the court determines to be necessary to secure payment of any further compensation, costs, or interest that may be recovered in the proceeding. After the making of such an order, the court may, on motion of any party, order an increase or a decrease in such additional amount. A defendant may withdraw the amount deposited under this section or a portion thereof only if it is determined that he is entitled to recover such amount in the proceeding.
