How is an estate that is to revert back to the original owner upon a certain condition fulfilled described?

A determinable fee estate is characterized by its automatic reversion back to the original owner when a specific condition is met. This type of estate is typically established through language in the deed that incorporates a condition connected to the use of the property. For example, if a property is granted with the stipulation that it must only be used for educational purposes, the estate would automatically revert to the grantor if that condition is violated.

The key aspect of a determinable fee estate is the unconditional nature of that reversion, as it does not require any action or legal maneuvering by the original owner to reclaim the property; it simply happens automatically when the condition fails. The other options describe different types of ownership or conditions that do not have the same automatic reversion feature as a determinable fee estate.
