Mo. Rev. Stat. § 469.600

The doctrine of worthier title and the Rule in Bingham's case is abolished as a rule of law and as a rule of construction. Language in a governing instrument describing the beneficiaries of a disposition as the transferor's "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.
