California Code, Code of Civil Procedure - CCP § 1353

Except as otherwise provided in Sections 401 or 1352, whenever money or other property is deposited in the State Treasury under the provisions of this title, and, except as otherwise provided by law, when there is in the possession of the State or its officers any money or other property which is to be held for third persons or the title to which has vested in the State subject to the rights of third persons, the Superior Court of the County of Sacramento shall have full and exclusive jurisdiction to determine the title to such money or other property and all claims thereto.

If the period in which such money or other property may be claimed by a person entitled thereto has not terminated, such period and person being prescribed by law, any such person may file a petition in the Superior Court of the County of Sacramento, or as provided in Section 401, showing his claim or right to the money or other property or the proceeds thereof, or any portion thereof.

The petition shall be verified, and, among other things, must, insofar as they are applicable or material to the matters at issue, state the facts required to be stated in a petition filed under Section 1355. If the money or other property at issue did not come into the possession of the State or its officers in connection with estates of deceased persons, the petition shall, in addition to the foregoing facts, state any material facts necessary to establish a prima facie right or title in the petitioner. Upon the filing of the petition, the same proceedings shall be had as are required in Section 1355.

If, upon trial of the issues, the court is satisfied of the claimant's right or title to the money or other property claimed, it shall grant him a certificate to that effect under its seal. Upon presentation of such certificate, the Controller shall draw his warrant on the Treasurer for the amount of money covered thereby; and if the certificate covers any property other than money, a certified copy of the certificate filed with the officer of the State having possession of the property shall serve as sufficient authority to the officer for the delivery of such property to the claimant.
