springing executory interest
Springing executory interest is a future interest in a third-party transferee that divests the grantor’s interests at a future time. It transfers the rights in property from a grantor to the third-party transferee when a specific event occurs. It is often used to ensure that the property is used for a specific purpose or that the third-party transferee only has the ownership when the conditions that the grantor intends to happen are met.
