Wyo. Stat. § 26-15-123
If the proceeds of or payments under any life or disability insurance policy or annuity contract are payable in accordance with the terms of the policy or contract, or the exercise of any right or privilege thereunder, and the insurer makes payment thereof in accordance with those terms or in accordance with any written assignment thereof, the person then designated as being entitled thereto is entitled to receive the proceeds or payments and to give full acquittance therefor. The payments fully discharge the insurer from all claims under the policy or contract unless, before payment is made, the insurer receives at its home office written notice by or on behalf of some other person that the other person claims to be entitled to the payment or some interest in the policy or contract.
