A shifting executory interest cuts short someone other than the grantor. For example, if O conveys property "To A, but if B returns from Florida within the next year, to B"; here, B has a shifting executory interest, and A has a fee simple subject to this shifting executory interest. A shifting executory interest may be premised on any event, irrespective of whether that event is under the control of one party or the other, or if it is an external event under the control of neither party. For example, a conveyance "To A, but if the property is ever used as a commercial dairy, to B" would leave A in control of the condition; so long as A does not use the property in the proscribed manner it will remain hers. Conversely, a conveyance "To A, but if B receives a law degree, to 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".
