Cal. Code of Civil Procedure § 1519.5

Subject to Section 1510, any sums held by a business association that have been ordered to be refunded by a court or an administrative agency including, but not limited to, the Public Utilities Commission, which have remained unclaimed by the owner for more than one year after becoming payable in accordance with the final determination or order providing for the refund, whether or not the final determination or order requires any person entitled to a refund to make a claim for it, escheats to this state. It is the intent of the Legislature that the provisions of this section shall apply retroactively to all funds held by business associations on or after January 1, 1977, and which remain undistributed by the business association as of the effective date of this act. Further, it is the intent of the Legislature that nothing in this section shall be construed to change the authority of a court or administrative agency to order equitable remedies.
