executory interest การใช้

Executory interests usually arise when a grantor gives property to one person, provided that they use it a certain way.
The holder of an executory interest, however, has no standing to enforce an action for waste, since his future interest is not vested.
Other jurisdictions apply the " wait and see " or " cy-pr鑣 doctrine " that validates contingent remainders and executory interests that would be void under the traditional rule in certain circumstances.
Executory interests are subject to the rule against perpetuities, which disqualifies any interest that can vest more than twenty-one years after the death of every party who was living at the time the interest was created.
Executory limitations transferring ownership from the grantor to a third party are called " springing executory interests ", and those that transfer from the grantee to a third party are called " shifting executory interests ".
