Property
Reversion
Definition
A reversion is a future interest retained by the grantor when the grantor conveys a lesser estate than they own. For example, if O (who has a fee simple) conveys a life estate to A, O retains a reversion in fee simple — upon A's death, the property returns to O or O's heirs. Reversions are vested interests, freely alienable, and not subject to the Rule Against Perpetuities. They arise automatically by operation of law whenever the grantor transfers less than their full interest.
Example
O conveys Blackacre "to A for life." O retains a reversion because O conveyed less than a fee simple. When A dies, Blackacre returns to O.
