California Code, Code of Civil Procedure - CCP § 694.030

(a) Except for a judgment described in Section 683.310 or 683.320, the period for enforcement of a money judgment or a judgment for possession or sale of property entered prior to the operative date is governed on and after the operative date by Chapter 3 (commencing with Section 683.010).

(b) Notwithstanding subdivision (a), even though a judgment to which subdivision (a) applies is not renewable pursuant to Chapter 3 (commencing with Section 683.010) because the time for filing an application for renewal has expired, the judgment may be renewed under Chapter 3 (commencing with Section 683.010) if the court which entered the judgment determines, on noticed motion filed within two years after the operative date, that authority to enforce the judgment after the 10-year period provided in former Section 681 would have been granted if a motion had been made under former Section 685 and the court, in its discretion, makes an order authorizing the renewal of the judgment. The notice of motion shall be served personally or by mail on the judgment debtor.
