(a)
(1) The owner of a benefit contract shall have the right at all times to change the beneficiary or beneficiaries in accordance with the laws or rules of the society unless the owner waives this right by specifically requesting in writing that the beneficiary designation be irrevocable.
(2) Through its laws or rules, a society may limit the scope of beneficiary designations and shall provide that no revocable 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 benefit contract.
(b) A society may make provision for the payment of funeral benefits to the extent of such portion of any payment under a certificate as might reasonably appear to be due to any person equitably entitled thereto by reason of having incurred expense occasioned by the burial of the member.
(c) If, at the death of any member, there is no lawful beneficiary to whom the insurance benefits are payable, the amount of such benefits, except to the extent that funeral benefits may be paid as provided in subsection (b) of this section, shall be payable to the personal representative of the deceased insured. However, if the owner of the certificate is other than the insured, the proceeds shall be payable to such an owner.
