B" places B entirely in control of the dispensation of the property; if B is able to fulfill the condition, B will get the property irrespective of what A does. Finally, the interest may shift based on a wholly external event, for example, "To A, but if the Cleveland Browns win the Super Bowl, to B". If the conveyance to A is for a limited time, or for the life of A, then the condition triggering the executory interest must occur within that time, or the property will return to the grantor. Example: "O grants Blackacre to A for life, but if A ever drinks alcohol, then Blackacre immediately goes to B." A has a possessory interest in life estate subject to executory limitation (B's executory interest). B has an executory interest, because his interest does not vest unless A's life estate terminates due to the 'unnatural' condition subsequent. The interest is shifting, because if A drinks, then the property "shifts" from one grantee to another. If A never drinks, then A will retain ownership, and on A's death the property will go to O, or the heirs of O. Springing executory interest A springing executory interest divests the grantor's own interest, in favor of the grantee. For example, O conveys to A for life, and one year after A's death to B and his heirs. O will have a one-year interest, that will spring/be cut short one year after A's death, and will go to B, the grantee. Suppose B is 15 years old. Example: "O grants Blackacre to A for life and one year after A's death, to B if B reaches the age of 25 years." Analysis (O): O has a reversion (see above), since there is a one year gap between A's estate and the succeeding estate Analysis (A): A has a possessory interest for life Analysis (B): B has a springing executory interest, since B's future interest follows the reversion to O, and if B reaches the age of 25 years after A's death B's interest sets aside O's interest and claims the Fee Simple Limitations on the creation of executory interests The grantor never retains an ultimate future interest when there is an executory condition present. If the executory condition is never met, the original grantee retains the interest, while if the condition is met, the interest transfers to a third party. However, the
