Wyo. Stat. § 34-1-137: Fees tail prohibited; future interests of fees tail; worthier title doctrine abolished.

(a) The creation of fees tail is not permitted. The use in an otherwise effective conveyance of property of language appropriate to create a fee tail, creates a fee simple in the person who would have taken a fee tail. Any future interest limited upon such an interest is a limitation upon the fee simple and its validity is determined accordingly.

(b) The doctrine of worthier title is abolished as a rule of law and as a rule of construction. Language in a will, trust agreement, beneficiary designation or other governing instrument describing the beneficiaries of a disposition as "heirs," "heirs at law," "next of kin," "distributees," "relatives" or "family" or language of similar import, does not create or presumptively create a reversionary interest in the transferor.
