Which fee simple estate will revert back to the grantor under certain conditions?

In the context of real property law, the fee simple on condition subsequent is a type of fee simple estate that allows the grantor to reclaim the property if a specific condition occurs or is violated. This kind of estate includes a condition attached to the ownership such that if the condition is breached, the original owner has the right to take back the property.

The defining feature of a fee simple on condition subsequent is that the grantor retains a right of entry, which means that they can choose to re-enter the property and reclaim ownership if the specific condition is not met. Unlike a fee simple determinable, which automatically reverts back to the grantor upon the occurrence of a condition, a fee simple on condition subsequent requires the grantor to take affirmative action to reclaim the property, thus granting them some control over the circumstances.

In contrast, a fee tail estate is designed to keep the property within a family line and does not revert back to the grantor under specified conditions. A fee simple determinable automatically reverts to the grantor when the stated condition occurs, and a leasehold interest is temporary and does not have a reversionary interest tied to specific conditions in the way a fee simple on condition subsequent does.
