La. Stat. tit. 22 § 877
Whenever the proceeds of, or payments under a life endowment or health and accident insurance policy or any annuity contract issued by a life insurance company become payable and the insurer makes payment thereof in accordance with the terms of the policy or contract or in accordance with any written assignment thereof or of any interest thereunder, hereafter made, the person then designated in the policy or contract or by such assignment as being entitled thereto, shall be entitled to receive such proceeds or payments and to give full acquittance therefor, and such payment shall fully discharge the insurer from all claims under the policy or contract unless, before payment is made, the insurer has received at its home office, written notice by or on behalf of some other person that such other person claims to be entitled to such payment or some interest in the policy or contract. Nothing contained in this Section shall affect any claim or right to any policy or contract or the proceeds thereof or payments thereunder as between persons other than the insurer.
