Wyo. Stat. § 26-15-122
A policy is assignable or not assignable as provided by its terms. Subject to its terms relating to assignability, any life or disability policy, under the terms of which the beneficiary may be changed upon the sole request of the insured or owner, may be assigned either by pledge or transfer of title, by an assignment executed by the insured or owner alone and delivered to the insurer, whether or not the pledgee or assignee is the insurer. The assignment entitles the insurer to deal with the assignee as the owner or pledgee of the policy in accordance with the terms of the assignment, until the insurer receives at its home office written notice of termination of the assignment or pledge, or written notice by or on behalf of some other person claiming some interest in the policy in conflict with the assignment.
