Common law

The rule does not apply to interests in the grantor himself. For example, the grant "For A so long as alcohol is not sold on the premises, then to B" would violate the rule as to B. The conveyance to B would be stricken, leaving "To A so long as alcohol is not sold on the premises." This would create a fee simple determinable in A, with a possibility of reverter in the grantor (or the grantor's heirs). The grant to B would be void as it is possible alcohol would be sold on the premises more than 21 years after the deaths of A, B, and the grantor. However, as the rule does not apply to grantors, the possibility of reverter in the grantor (or his heirs) would be valid.
