Final answer:
A future estate is postponed until the termination of the life estate.
Step-by-step explanation:
When a life estate is created by the fee simple owner and a future estate is simultaneously created, the future estate is postponed until the termination of the life estate. A life estate is a type of ownership interest in land that only lasts for the duration of someone's life. Therefore, the future estate is postponed until the current life estate holder passes away.
