No beneficiary shall have or obtain any vested interest in the proceeds of any certificate until the certificate has become due and payable in conformity with the provisions of the insurance contract. The owner of a certificate shall have the right at all times to change the beneficiary or beneficiaries in accordance with the constitution, laws, or rules of the society, unless the owner waives this right by specifically requesting in writing that the beneficiary designation be irrevocable. Every society, by its constitution, laws, or rules, may limit the scope of beneficiaries only to the extent required by federal law governing fraternal benefit societies.
