What term describes terminating the rights of the leasehold owner and returning the property to fee simple?

The term that describes terminating the rights of the leasehold owner and returning the property to fee simple is known as Ground Rent Ejectment. This legal process allows the fee simple owner, typically the landlord, to reclaim ownership of the property after the leasehold period has ended or if the leaseholder fails to meet their obligations under the lease agreement.

Ground Rent Ejectment specifically pertains to situations involving properties that are subject to ground rents, a form of encumbrance where the land is owned by one party and leased to another. When the leaseholder's rights are terminated, the property reverts back to the fee simple owner, effectively transferring full ownership rights back to them.

This process is distinct from other terms such as Ground Rent Repossession, which may imply a more informal reclaiming of property rights without the legal formalities, or Ground Rent Renewal and Ground Rent Reinstatement, which refer to maintaining or extending the existing lease terms rather than terminating them. Ground Rent Ejectment is specifically focused on the legal cessation of a leasehold interest, making it the correct answer in this context.
