Notwithstanding Sections 751 and 1100 of the Family Code and Section 249.5 of the Probate Code, when the proceeds of, or payments under, a life insurance policy become payable and the insurer makes payment thereof in accordance with the terms of the policy, or in accordance with the terms of any written assignment thereof if the policy has been assigned, that payment shall fully discharge the insurer from all claims under the policy unless, before that payment is made, the insurer has received, at its home office, written notice by or on behalf of some other person that the other person claims to be entitled to that payment or some interest in the policy.
