Which type of estate can endure indefinitely, as long as the conditions are met?

The option indicating a Fee Simple Absolute is the only type of estate that can endure indefinitely without any conditions attached. A Fee Simple Absolute grants the owner the maximum possible rights to the property, allowing them to use it, sell it, or pass it on to heirs without limitation or expiration. This means that as long as the owner of the Fee Simple Absolute maintains ownership, the estate persists indefinitely, and their property rights are not subject to any specific conditions or terms.

In contrast, other types of estates like the Fee Simple Determinable arise with specific conditions that, if violated, can lead to the automatic termination of the estate. A Life Estate is limited to the duration of an individual's life, meaning it cannot persist beyond that person's lifetime. A Leasehold Estate is temporary and is defined by the terms of a lease agreement, which has a specified duration and can be terminated at the end of that period. Thus, only the Fee Simple Absolute offers a truly indefinite duration as long as ownership is maintained.
