Future Interests — Identify future interests - Bar Exam Uniform

SECTION 1

Historical Context & Motivation

The doctrine of future interests is one of the oldest and most conceptually demanding areas of Anglo-American property law. Its roots stretch back to feudal England, where the rigid tenurial system demanded precise rules about who held seisin—the right to present possession of land—and who stood in line to take possession in the future. Because land was the primary source of wealth and political power, the ability to control its devolution across generations became a central preoccupation of the English aristocracy, and the common-law courts developed an elaborate taxonomy to govern these arrangements. Understanding why these categories exist, rather than merely memorizing them, is the key to identifying future interests reliably on the bar examination.

1285 • Statute De Donis Conditionalibus

Parliament enacted the Statute De Donis to protect family dynasties by creating the fee tail, an estate that descended automatically to the grantee's lineal heirs and could not be alienated. This statute gave rise to the reversion held by the grantor upon the extinction of the bloodline.

1536 • Statute of Uses

Henry VIII's Statute of Uses converted equitable interests under a use into legal estates, permitting grantors to create executory interests that could spring up or shift from one grantee to another upon the occurrence of a stated condition.

1682 • Duke of Norfolk's Case

The English Court of Chancery articulated the Rule Against Perpetuities in embryonic form, imposing temporal limits on contingent future interests to prevent families from tying up land indefinitely.

1769 • Blackstone's Commentaries

William Blackstone systematized the classification of present possessory estates and their correlative future interests, creating the framework that American law schools and bar examiners still use today.

1944 • Restatement (First) of Property

The American Law Institute published the Restatement, codifying the five recognized categories of future interests and standardizing the terminology used by courts and commentators across U.S. jurisdictions.

The central question this area of law addresses is deceptively simple: when a grantor conveys less than a fee simple absolute, what happens to the remaining interest, and who holds it? The answer depends on whether the future interest is retained by the grantor or created in a third-party grantee, and whether the interest is certain or contingent. These distinctions carry enormous practical consequences, affecting alienability, taxation, creditor access, and the applicability of the Rule Against Perpetuities.

SECTION 2

Core Principles & Definitions

A future interest is a present, legally protected right to the future enjoyment of property. Despite its name, a future interest is not merely an expectancy; it is a presently existing property interest that entitles its holder to possession at some point in the future, upon the natural or premature termination of a preceding possessory estate. The entire system rests on a foundational axiom: every acre of land must be "owned" by someone at every moment in time. When a grantor carves out a possessory estate that is less than a fee simple absolute, the remaining quantum of ownership must reside somewhere—either in the grantor or in a designated third party. Correctly identifying the future interest requires a methodical two-step inquiry: first, determine who holds the interest (grantor or grantee); second, classify the interest within the appropriate sub-category by examining the language of the grant and the nature of the preceding estate.

Grantor vs. Grantee Distinction

Future interests fall into two families. Grantor-retained interests include reversions, possibilities of reverter, and rights of entry. Grantee-created interests include remainders (vested and contingent) and executory interests (springing and shifting).

Vested vs. Contingent

A future interest is vested if the holder is ascertained and no condition precedent (other than the natural termination of the preceding estate) must be satisfied. It is contingent if either the holder is unascertained or a condition precedent must occur before the interest becomes possessory.

Natural vs. Premature Termination

A possessory estate can end naturally (e.g., a life estate ending at the tenant's death) or prematurely through a condition subsequent or a limitation. The type of termination determines whether the future interest is a remainder (follows natural termination) or an executory interest (divests the preceding estate before its natural end).

Words of Limitation vs. Condition

Durational language ("so long as," "while," "during," "until") creates a fee simple determinable with a possibility of reverter. Conditional language ("but if," "on condition that," "provided that") creates a fee simple subject to condition subsequent with a right of entry.

Rule Against Perpetuities (RAP)

Contingent remainders, executory interests, and vested remainders subject to open are subject to the RAP. Grantor-retained interests (reversions, possibilities of reverter, rights of entry) and indefeasibly vested remainders are exempt. This distinction is why correct classification is essential.

✦

KEY TAKEAWAY

Think of ownership as a complete pie. When a grantor conveys a life estate, the grantor has given away only a slice—the right to use the land during the tenant's lifetime. The rest of the pie (the future interest) must belong to someone. If the grantor keeps it, it is a reversion. If the grantor hands it to a named third party, it is a remainder or an executory interest. Your job on every exam question is to account for every slice of the pie: identify the present possessory estate, then identify who holds each remaining slice and what label attaches to it.

SECTION 3

Visual Explanation — The Future Interest Classification Tree

The following decision-tree diagram provides a systematic method for identifying any future interest. Begin at the top by asking whether the interest is retained by the grantor or created in a third-party grantee, then follow the branches based on the characteristics of the preceding possessory estate and the language of the grant.

Start at the top by determining whether the grantor retains the interest or a third-party grantee receives it. For grantor-retained interests, match the type of preceding defeasible estate. For grantee interests, determine whether the interest follows the natural termination of the prior estate (remainder) or cuts it short (executory interest), then refine using the vested/contingent distinction.

The diagram reveals the hierarchical logic that governs classification. Notice that the first branch—grantor versus grantee—is dispositive of entire categories of future interests. A grantor can never hold a remainder or an executory interest; those labels apply exclusively to third parties. Conversely, a grantee can never hold a reversion, possibility of reverter, or right of entry. This structural constraint eliminates many incorrect answer choices on bar exam questions before you even analyze the specific language of the conveyance.

SECTION 4

How It Works — The Three-Step Identification Method

Identifying future interests on the bar exam is not an exercise in intuition; it is a mechanical process that, once internalized, yields reliable results. The method involves three sequential steps, each of which narrows the universe of possible answers. Applying these steps consistently transforms even the most complex conveyance into a solvable problem.

Step 1 — Parse the Conveyance and Identify the Present Possessory Estate

Read the grant language and determine the present possessory estate that is created. The five possessory estates—fee simple absolute, fee simple determinable, fee simple subject to condition subsequent, fee simple subject to executory limitation, fee tail, life estate, and term of years—each correlate with specific future interests. A fee simple absolute, by definition, leaves no future interest in anyone because the grantor has conveyed the entire "pie." Every other estate leaves some residual interest.

Step 2 — Determine Who Holds the Future Interest

Ask: does the future interest remain with the grantor (or grantor's heirs), or has it been given to a third-party grantee? If the conveyance names no one to take after the present estate holder, the interest remains with the grantor by default. This is the crucial fork in the classification tree: grantor-retained interests and grantee-created interests are entirely different taxonomic categories with different names, different rules regarding alienability, and different treatment under the Rule Against Perpetuities.

Step 3 — Apply the Classification Rules

Present Possessory Estate	Future Interest in Grantor	Future Interest in Grantee
Fee Simple Absolute	None	None
Fee Simple Determinable	Possibility of Reverter	Shifting Executory Interest
Fee Simple Subject to Condition Subsequent	Right of Entry	Shifting Executory Interest
Fee Simple Subject to Executory Limitation	N/A (interest is in grantee by definition)	Executory Interest (shifting or springing)
Life Estate	Reversion	Remainder (vested or contingent)
Fee Tail	Reversion	Remainder (vested or contingent)
Term of Years	Reversion	Remainder (vested or contingent)

Correlation between present possessory estates and their corresponding future interests

⚠

EXAM TIP

When a conveyance creates a fee simple determinable or fee simple subject to condition subsequent and names a third party to take upon the triggering event, the future interest in the third party is always an executory interest, not a remainder. This is because the third party's interest divests the fee estate holder—it does not wait patiently for the estate to end naturally. Many students misclassify this as a remainder; remember that a remainder never divests or cuts short the preceding estate.

SECTION 5

Detailed Breakdown — Types of Remainders

Because remainders are the most frequently tested future interest on the bar examination, a granular understanding of the four sub-types is essential. The distinctions among them determine not only the holder's rights but also whether the interest is subject to the Rule Against Perpetuities and whether it is alienable inter vivos.

This diagram contrasts the four main remainder sub-types. Note the critical distinction: vested remainders require an ascertained holder with no condition precedent, while contingent remainders fail one or both of those requirements. The RAP status of each sub-type is noted at the bottom of each card.

A vested remainder subject to total divestment (sometimes called a "vested remainder subject to complete defeasance") deserves special attention because it is easily confused with a contingent remainder. The critical distinction lies in the placement of the condition. If the condition appears before the gift language ("to B if B graduates"), it is a condition precedent making the remainder contingent. If the condition appears after the gift language ("to B, but if B fails to graduate, then to C"), B has a vested remainder subject to total divestment, and C holds a shifting executory interest. This "comma rule" is a reliable heuristic, though courts occasionally look past punctuation to the grantor's intent.

💡

THE PAIRED CONTINGENT REMAINDER RULE

Whenever a conveyance creates a contingent remainder, look for a corresponding alternative contingent remainder or a reversion in the grantor. The principle that "someone must hold seisin at every moment" means that if the contingent remainder fails to vest, the interest must go somewhere. For example, "O to A for life, then to B if B passes the bar, otherwise to C" creates a life estate in A, a contingent remainder in B, an alternative contingent remainder in C, and—because both remainders might fail in some jurisdictions—a reversion in O. Always account for every possible outcome.

SECTION 6

Worked Example — Identifying All Future Interests in a Complex Conveyance

Consider the following conveyance: "O conveys Blackacre to A for life, then to B and her heirs if B has graduated from law school, but if B has not graduated from law school at A's death, then to C and his heirs." At the time of conveyance, A is alive and B has not yet graduated from law school.

Classifying All Interests in a Complex Grant

1
Step 1 — Identify the Present Possessory Estate

The operative language "to A for life" creates a life estate in A. A life estate is a possessory estate measured by the duration of the grantee's (A's) natural life. It will terminate naturally upon A's death.

A holds a life estate.
2
Step 2 — Identify B's Interest

The language "then to B and her heirs if B has graduated from law school" creates an interest in B that follows the natural termination of A's life estate. Because B's interest waits patiently for A's life estate to end (rather than cutting it short), it is a remainder, not an executory interest. Next, we determine whether it is vested or contingent. B is ascertained (she is a named, living person), but there is a condition precedent—B must have graduated from law school by the time of A's death. Because a condition precedent exists, this is a contingent remainder.

B holds a contingent remainder in fee simple absolute.
3
Step 3 — Identify C's Interest

The language "but if B has not graduated from law school at A's death, then to C and his heirs" gives C an interest that also follows A's life estate. C's interest will become possessory only if B's condition precedent is not met. Like B's interest, C's interest is a remainder—it follows the natural end of A's life estate. C is ascertained, but the condition precedent (B's failure to graduate) must occur for C to take. This makes C's interest an alternative contingent remainder. B and C hold paired contingent remainders: exactly one of them will vest at A's death.

C holds an alternative contingent remainder in fee simple absolute.
4
Step 4 — Identify O's Interest (If Any)

Although B and C between them cover the two possible outcomes at A's death (either B has graduated or B has not), many authorities recognize that because both remainders are contingent, there exists a theoretical possibility—however unlikely—that neither vests (e.g., if the grant is construed as requiring B or C to survive A, and one of them predeceases). Under the common-law analysis favored by most bar exam questions, O retains a reversion as a "safety net." This reversion is vested (all reversions are) but may be divested if one of the contingent remainders vests.

O retains a reversion (subject to divestment).
5
Step 5 — Summary of All Interests

Assembling the complete picture: A has a present possessory life estate; B has a contingent remainder in fee simple absolute (contingent on graduating law school); C has an alternative contingent remainder in fee simple absolute (contingent on B's failure to graduate); and O retains a reversion. Both B's and C's contingent remainders are subject to the Rule Against Perpetuities, but they are valid under the RAP because the condition will necessarily be resolved at A's death, which occurs during A's own lifetime (a measuring life in being).

All interests are valid. The full state of title: A — life estate; B — contingent remainder; C — alternative contingent remainder; O — reversion.

SECTION 7

Key Distinctions & Common Pitfalls

Bar exam questions test your ability to distinguish between interests that are superficially similar but legally distinct. The following comparison table highlights the most commonly tested contrasts and the language cues that differentiate them.

Feature	Remainder	Executory Interest
Relationship to Prior Estate	Follows the natural termination of a finite prior estate (life estate, fee tail, term of years)	Divests or cuts short the prior estate before its natural end
Can Follow a Fee Simple?	Never — a remainder cannot follow a fee simple estate of any kind	Yes — an executory interest can follow a fee simple determinable or fee simple subject to executory limitation
Subject to RAP?	Contingent remainders and VRSOs: Yes. Indefeasibly vested and VRSTD: No	Always subject to the RAP
Typical Language	"then to B," "remainder to B," "and after A's death, to B"	"but if X occurs, to B," "one year after A's death, to B"
Sub-Types	Indefeasibly vested, vested subject to open, vested subject to total divestment, contingent	Springing (divests grantor) or Shifting (divests grantee)

Remainder vs. Executory Interest — The Most Commonly Tested Distinction

🔑

CRITICAL DISTINCTION

Think of remainders as polite dinner guests: they wait in the foyer until the host (the life tenant) finishes and opens the door. Executory interests, by contrast, are uninvited guests who barge in and physically remove the current occupant when a triggering event occurs. If the future interest can "barge in" and divest someone, it is an executory interest. If it patiently waits for the preceding estate to end on its own, it is a remainder. This metaphor resolves the majority of classification questions.

SECTION 8

Connection to Advanced Doctrines

Correctly identifying future interests is not an end in itself on the bar examination—it is the prerequisite to applying advanced doctrines that turn on classification. Three doctrines in particular depend on accurate identification: the Rule Against Perpetuities (RAP), the Doctrine of Destructibility of Contingent Remainders, and the Rule in Shelley's Case. Understanding how identification connects to these doctrines will strengthen your ability to answer multi-issue property questions.

Advanced Doctrine	Requires Identification of…	Why It Matters
Rule Against Perpetuities	Contingent remainders, VRSOs, and executory interests	Only these interests are tested under the RAP. If the interest must vest or fail within 21 years of a life in being, it is valid; otherwise, it is void ab initio under the common-law RAP.
Destructibility of Contingent Remainders	Contingent remainders in land	Under the common-law rule (largely abolished), a contingent remainder was destroyed if it failed to vest at or before the termination of the preceding freehold estate. Executory interests were immune from destruction.
Rule in Shelley's Case	Remainder in the grantee's heirs	If a grantor creates a life estate in A and a remainder in A's heirs (in the same instrument), the Rule in Shelley's Case merges the two interests, giving A a fee simple. This rule applies only to remainders, not executory interests.
Doctrine of Worthier Title	Remainder in grantor's heirs	When a grantor creates a remainder in the grantor's own heirs, the doctrine converts that remainder into a reversion in the grantor. This is a rule of construction (rebuttable by evidence of intent) in most jurisdictions.

How future interest classification feeds into advanced property doctrines

On the Multistate Bar Examination, future interest identification rarely appears in isolation. A typical question will present a conveyance, ask you to classify the interests, and then ask a follow-up question that requires you to apply one of these advanced doctrines. By mastering the classification step, you create the foundation on which every subsequent analytical layer rests. The Uniform Bar Examination increasingly tests these doctrines in the context of modern statutory modifications—such as the Uniform Statutory Rule Against Perpetuities (USRAP), which provides a 90-year wait-and-see period—but the common-law categories remain the baseline framework.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

O conveys Blackacre "to A for life." O says nothing about what happens after A's death and names no third party. What future interest exists, and who holds it?

Show answer

O retains a reversion in fee simple absolute. When a grantor conveys a life estate without designating any third party to take upon the life tenant's death, the remaining interest automatically stays with the grantor. A reversion arises whenever the grantor transfers an estate of lesser quantum than the estate the grantor holds. Because reversions are vested interests retained by the grantor, they are not subject to the Rule Against Perpetuities. Upon A's death, possession reverts to O (or O's successors).

Question 2: BASIC CALCULATION

O conveys Greenacre "to A and her heirs so long as the land is used for agricultural purposes." Identify A's present possessory estate and O's future interest.

Show answer

A holds a fee simple determinable, as indicated by the durational language "so long as." O retains a possibility of reverter. A fee simple determinable automatically terminates when the stated condition occurs (cessation of agricultural use), and upon that automatic termination, title reverts to O without any affirmative action by O. The possibility of reverter is a grantor-retained interest and is exempt from the Rule Against Perpetuities. If the conveyance had used conditional language ("but if," "on condition that"), A would hold a fee simple subject to condition subsequent, and O would retain a right of entry instead.

Question 3: INTERMEDIATE

O conveys Whiteacre "to A for life, then to B and her heirs; but if B ever uses the land as a tavern, then to C and his heirs." Identify every interest created at the time of conveyance.

Show answer

A holds a life estate. B holds a vested remainder subject to total divestment (VRSTD) in fee simple. B's remainder is vested because B is ascertained and no condition precedent must be satisfied before B takes—B takes automatically upon A's death. However, B's estate is subject to a condition subsequent (using the land as a tavern) that could divest B's interest entirely. C holds a shifting executory interest in fee simple absolute. C's interest is executory because it would divest B's fee simple estate (not wait for it to end naturally). C's executory interest is subject to the Rule Against Perpetuities. Under the common-law RAP, C's interest is void because B could potentially operate a tavern more than 21 years after the death of all lives in being at the time of the conveyance. O retains no interest because B's vested remainder accounts for the entire fee.

Question 4: APPLIED

O conveys Redacre "to A for life, then to such of A's children who reach age 21." At the time of conveyance, A is alive and has two children: B (age 25) and C (age 15). Identify all interests.

Show answer

A holds a life estate. B holds a vested remainder subject to open (VRSO) in fee simple absolute. B's interest is vested because B is ascertained and has already satisfied the condition precedent (reaching age 21). However, the class of "A's children who reach age 21" is still open because A could have additional children, and C could reach 21, so B's share may be diluted—hence "subject to open." C holds a contingent remainder because C has not yet satisfied the condition precedent of reaching age 21. O retains a reversion, because it is possible that A's only qualifying child (B) predeceases A and C fails to reach 21, leaving no one to take the remainder. The VRSO in B is subject to the Rule Against Perpetuities but is valid because the class will close at A's death (the class-closing rule of convenience), and A is a life in being.

Question 5: CRITICAL THINKING

O conveys Bluacre "to A for life, then to B for life, then to C and her heirs if C survives B, but if C does not survive B, then to D and his heirs." At the time of the conveyance, all parties are alive. Identify every present possessory estate and every future interest. Also determine which interests, if any, are subject to the Rule Against Perpetuities, and whether they are valid.

Show answer

A holds a present possessory life estate. B holds a vested remainder in a life estate (sometimes called a "vested remainder for life")—B is ascertained, no condition precedent exists, and B's interest follows the natural end of A's life estate. C holds a contingent remainder in fee simple absolute, contingent on surviving B. D holds an alternative contingent remainder in fee simple absolute, contingent on C not surviving B. O retains a reversion because both C's and D's remainders are contingent. Regarding the Rule Against Perpetuities: B's vested remainder in a life estate is exempt (it is indefeasibly vested). C's and D's contingent remainders are subject to the RAP. Both are valid because the contingency (whether C survives B) will necessarily be resolved at B's death. B is a life in being at the time of the conveyance, so the interests will vest or fail within B's lifetime—well within the perpetuities period of a life in being plus 21 years. O's reversion, as a grantor-retained interest, is exempt from the RAP.

SUMMARY

Summary — Future Interests Identification

Summary

Identifying future interests requires a systematic approach. First, determine the present possessory estate created by the conveyance—life estate, fee tail, term of years, or one of the defeasible fees. Second, determine whether the future interest is retained by the grantor (yielding a reversion, possibility of reverter, or right of entry) or given to a third-party grantee (yielding a remainder or an executory interest). Third, refine the classification: remainders are either vested (indefeasibly, subject to open, or subject to total divestment) or contingent; executory interests are either springing (divesting the grantor) or shifting (divesting another grantee).

Always remember: a remainder never follows a fee simple estate and never divests the prior estate holder—it waits patiently for the natural end of a finite estate. An executory interest, by contrast, cuts short the prior estate. The Rule Against Perpetuities applies to contingent remainders, vested remainders subject to open, and all executory interests, but never to grantor-retained interests or indefeasibly vested remainders. Mastering this classification system is the gateway to every advanced property doctrine tested on the bar examination.
