Future interests kept by the grantor

The Grantor’s Residue: When Less Than Fee Simple Moves

A future interest kept by the grantor is identified by asking what estate the grantor transferred, whether someone else is entitled to take next, and whether the grantor’s return is automatic or requires a choice.

A reversion arises when a grantor transfers an estate smaller than the estate the grantor owns and leaves the balance in the grantor. The classic example is, “O conveys Blackacre to A for life.” A receives a life estate; O retains a reversion because the conveyance did not dispose of the ownership after A’s death. When A dies, O becomes entitled to possession.

The same analysis applies to a term of years: when a landlord leases property for five years, the landlord retains a reversion after the lease expires. The reversion is not a right that depends on a new conveyance or on the grantor’s decision to reclaim the land. It is the grantor’s remaining ownership after the smaller transferred estate ends.

Ask next whether the deed gives a future interest to someone else that will take possession instead. “To A for life, then to B” leaves no reversion in O because B, not O, is designated to take next. By contrast, “To A for life, then to B if B reaches thirty” leaves O a reversion while B’s future interest remains uncertain. The classification of B’s interest belongs to the sibling chapter on remainders, but the grantor-interest consequence is the point here: an uncertain third-party disposition leaves the undisposed possibility of possession in O.

A reversion can therefore exist even though the grantor did not write “then back to O.” It is identified from the gap left after the smaller estate and any effective third-party future interest are accounted for. Conversely, a grantor does not retain a reversion merely because property might someday return. If O conveys a fee simple subject to a limitation benefiting O, O retains either a possibility of reverter or a right of entry, depending on whether termination is automatic or requires O’s exercise of a reserved power. If the limitation shifts the estate to a third party, the third party holds an executory interest and O retains no future interest.

This topic is not starred: legal resources may be supplied when it is tested, and where they are not, you need only demonstrate recognition that the topic is at issue. You are not required to hold this topic cold because resources may be supplied; the floor you must still hold in memory is the vocabulary, the three-way classification, and the order of questions, because you will not know at item time whether resources are coming.

The Floor: The Trigger and the Grantor’s Choice

At speed, begin with the estate transferred, not with the label the question suggests.

1. If the grantor transferred less than the grantor’s entire estate, ask whether another person will take possession when that estate ends. If not, the grantor retains a reversion.

2. If the grantor transferred a fee simple with language limiting its duration in favor of the grantor, ask whether the estate ends automatically when the stated event occurs. If yes, the grantor retains a possibility of reverter. If the estate shifts to a third party, that third party holds an executory interest and the grantor retains no future interest.

3. If the estate does not end automatically but the deed reserves a power for the grantor to terminate it after a stated condition, the grantor retains a right of entry, also called a power of termination.

The key near-miss is the difference between an automatic consequence and a reserved election. “To the city so long as the land is used as a park” ordinarily makes the city’s estate end automatically when the land ceases to be used as a park. The grantor’s interest is a possibility of reverter. “To the city, but if the land is used for commercial purposes, the grantor may reenter” makes the grantor’s interest a right of entry. The commercial use activates the power, but the city’s estate does not end until the grantor exercises it.

Durational words-“so long as,” “while,” “during,” and “until”-strongly signal automatic termination. Conditional language-“on condition that,” “provided that,” or “but if”-often signals a condition subsequent when the instrument also reserves a power to reenter. The entire conveyance controls if the wording points in different directions. A statement that the land “shall immediately revert” supports automatic termination; an express statement that the grantor “may reenter and terminate” supports a right of entry.

A promise to use land in a particular way is not automatically either interest. “To A, who promises to operate the land as a library” may create an obligation, but without language making the estate end automatically or reserving a termination power, the facts do not establish a possibility of reverter or right of entry. A future interest held by a third person is also neither: that boundary is addressed in the sibling chapter on executory interests.

You do not have to hold exact supplied element wording, exception lists, or numbered subsections. What must be available quickly is the distinction between a smaller estate and a defeasible fee, and between automatic termination and termination by grantor choice.

The Supplied Rule in Action: Reading the Deed at Speed

When a provision is supplied, locate its operative language first. Identify who conveyed what, the event that activates the interest, whether the provision says the estate ends automatically, and whether it reserves a power to terminate. Then check any exception-especially a third-party future interest-and map each fact to the provision rather than importing a different rule.

The screen supplies this provision:

A grantor retains a reversion when the grantor conveys an estate smaller than fee simple absolute and leaves a future interest in the grantor after that estate. A third-party vested or contingent remainder may coexist with a reversion after a lesser estate; a third-party executory interest following a fee simple subject to executory limitation leaves no reversion, possibility of reverter, or right of entry in the grantor.

A possibility of reverter accompanies a fee simple determinable. The estate is determinable when the conveyance uses words showing that it lasts only while, during, or so long as a stated condition continues. When the condition occurs, the estate ends automatically, without reentry by the grantor.

A right of entry accompanies a fee simple subject to condition subsequent. The estate does not end merely because the condition occurs. The grantor must have reserved a power to terminate the estate and must exercise that power.

If the conveyance uses mixed or unclear language, the entire instrument must be read to decide whether termination is automatic or depends on the grantor’s exercise of a power.

In 2012, Olivia conveyed Blackacre to the County “so long as Blackacre is used as a public park.”
In 2020, the County conveyed Blackacre to Developer.
In 2024, Developer stopped operating the property as a park and built a private office complex. Olivia immediately demanded possession but did not reenter the property.
The deed contained no language stating that Olivia “may reenter” or “may terminate” the County’s estate.

Recurring errors arise from these concrete misreads:

• Calling Olivia’s interest a reversion when the deed gives the County a fee “so long as” the park use continues confuses the size of the transferred estate.

• Calling the interest a right of entry when the deed says the estate “shall end automatically” ignores the absence of a grantor election.

• Treating a condition as self-executing when the deed says the grantor “may reenter” overlooks the required exercise of the reserved power.

• Treating “to A for life, then to B” as a reversion in O ignores that B is designated to take possession next.

• Treating “A promises to maintain a park” as a possibility of reverter without termination language turns an obligation into a future interest without support.

Three Short Calls: The Distinctions Under Time Pressure

High-Yield Points - ⚡ Biggest Takeaways

A smaller transferred estate leaves a reversion unless a third party is certain to take possession next. “So long as” ordinarily means automatic termination and a possibility of reverter. “May reenter” means the condition alone is insufficient: the grantor holds a right of entry and must act.
