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.
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.
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.

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.
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.
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) |
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.
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.
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.
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) |
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. |
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.
Practice Problems
Summary — Future Interests Identification
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.
