California Code, Insurance Code - INS § 1802.71

The holder, or former holder of a bail license, who has deposited with the commissioner securities in lieu of a bond as provided by Section 1802.7, may at any time substitute therefor a bond complying with the requirements of Section 1802, 1802.5, or 1803, as the case may be. Such a bond must embrace all liability theretofore existing or which may thereafter be incurred for the fulfillment of which the securities have been held, whether reported or unreported.

The substitution of such a bond for securities shall be conditioned upon the approval of the commissioner. Upon receiving such approval and the filing of the bond, the applicant shall be permitted to withdraw the securities theretofore deposited on his behalf.
