Cal. Insurance Code § 11020

If the commissioner finds that such contract is in conformity with the provisions of this chapter, that the financial statements are correct, that under it the interests of the certificate holders of the parties are properly protected and that the consolidation or merger is just and equitable to the members of each society, he shall approve the contract and issue his certificate to such effect. Upon such approval, the contract shall be in full force and effect unless any society which is a party to the contract is incorporated under the laws of any other state or territory. In such event the consolidation or merger shall not become effective unless and until it has been approved as provided by the laws of such state or territory and a certificate of such approval filed with the commissioner of this State or, if the laws of such state or territory contain no such provision, then the consolidation or merger shall not become effective unless and until the supervising insurance official of such state or territory has advised the commissioner that he has no objection to such consolidation or merger.
