Future Interests in Property Law

Future Interests in Property Law

1. Introduction

Property ownership does not always have to belong entirely to one person at one time.

A person can have the right to possess and use land today while another person already holds a legally recognized interest that will become possessory in the future. These interests are called future interests.

Future interests are especially important when property is divided over time. For example:

“To Alice for life, then to Bob.”

Alice has the present right to possess the property, but Bob already has a legal interest in the property. Bob does not possess the land yet. His interest becomes possessory when Alice’s life estate ends.

Future interests therefore require us to think about property in two dimensions:

• Who has the right to possess the property now?
• Who has the right to possess it later?

The law distinguishes several different types of future interests, and the distinctions matter because each type has different rules concerning transfer, inheritance, termination, and perpetuities.

The principal future interests are:

1. Reversion
2. Possibility of reverter
3. Right of entry (power of termination)
4. Remainder
5. Executory interest

Understanding these categories is essential to understanding estates in land, life estates, defeasible fees, wills, trusts, and many forms of estate planning.

---

2. What Is a Future Interest?

A future interest is a present legal interest in property that does not give its holder the present right to possess the property, but may give that person a right to possess it in the future.

The key word is present.

A future interest is not merely an expectation that someone might receive property someday. It is a legally recognized property interest that exists now.

For example:

“To Alice for life, then to Bob.”

Alice has a present possessory estate.

Bob has a future interest.

Bob’s interest exists immediately even though he cannot yet possess the property.

This distinction is important because a future interest can often be:

• transferred;
• inherited;
• devised by will;
• released;
• sold or assigned;
• affected by a mortgage or other transaction.

The precise rules depend on the type of future interest and the jurisdiction.

---

3. Present Possessory Estates and Future Interests

Future interests are easiest to understand when contrasted with present possessory estates.

A present possessory estate gives its holder the current right to possess the property.

A future interest does not currently give possession but may become possessory later.

Consider:

“To Alice for life, then to Bob.”

The arrangement can be visualized as:

Person	Interest	Present possession?
Alice	Life estate	Yes
Bob	Remainder	No
After Alice’s death	Bob’s interest becomes possessory	Yes

The property has therefore been divided temporally.

Alice has the property now.

Bob has the property later.

This temporal division is one of the central ideas of estates in land.

---

4. The Two Major Categories

Future interests are traditionally divided into two broad groups:

Interests retained by the transferor

These arise when the original owner transfers an estate but retains a future interest.

They include:

• reversion
• possibility of reverter
• right of entry

Interests created in a transferee

These are future interests given to another person.

They include:

• remainder
• executory interest

This distinction provides a useful starting point:

Future interest	Held by
Reversion	Transferor
Possibility of reverter	Transferor
Right of entry	Transferor
Remainder	Transferee
Executory interest	Transferee

The distinction becomes much easier once each category is examined separately.

---

5. Reversion

A reversion is a future interest retained by the transferor when the transferor conveys a smaller estate than the estate the transferor originally possessed.

The classic example involves a life estate.

“To Alice for life.”

Suppose the owner, O, owns Blackacre in fee simple absolute.

O conveys:

“To Alice for life.”

Alice receives a life estate.

What happens after Alice dies?

If the deed does not give the property to someone else, it returns to O.

O therefore retains a reversion.

Example

O → Alice for life.

The result is:

• Alice: life estate
• O: reversion

When Alice dies, O becomes entitled to possession.

---

6. Reversion After a Lease

Reversions are not limited to life estates.

They commonly arise from leases.

Suppose a landlord owns a property in fee simple and leases it to a tenant for ten years.

The tenant has a leasehold estate.

The landlord retains the future interest that follows the lease.

That interest is generally described as a reversion.

Thus:

Landlord → Tenant for ten years.

After ten years, assuming the lease has not otherwise been extended or terminated, possession returns to the landlord.

The landlord’s reversion therefore follows the tenant’s leasehold estate.

---

7. Reversion Is Not a Mere Expectation

A reversion is a legal property interest.

This is important because the holder of a reversion has more than a hope that the property will someday return.

The reversion exists at the time the smaller estate is created.

For example:

“To Alice for life.”

O does not cease having all legal interests in the property simply because Alice receives possession.

O retains the future interest.

The transfer has divided the ownership interest into present and future components.

---

8. Possibility of Reverter

A possibility of reverter is a future interest retained by the transferor following a fee simple determinable.

A fee simple determinable is an estate that automatically terminates when a specified condition occurs.

Typical language includes:

• “so long as”
• “while”
• “during”
• “until”
• “unless”

For example:

“To the City so long as the property is used as a public park.”

The city receives a fee simple determinable.

If the specified condition occurs—such as the property ceasing to be used as a public park—the estate automatically ends, subject to the jurisdiction’s rules.

The original owner retains a possibility of reverter.

Structure

O → City, so long as property is used as a park.

If the condition is violated:

City’s estate ends automatically → O becomes entitled to possession.

The future interest retained by O is the possibility of reverter.

---

9. Possibility of Reverter vs. Reversion

These interests are easy to confuse.

The basic distinction is:

Reversion	Possibility of reverter
Usually follows a transfer of a lesser estate	Follows a fee simple determinable
Does not depend on automatic termination by a condition	Arises from an estate that automatically terminates upon a specified event
Example: “To Alice for life”	Example: “To Alice so long as…”
Transferor retains future interest	Transferor retains future interest

A useful memory device is:

Reversion follows a smaller estate.

Possibility of reverter follows a fee simple determinable.

---

10. Right of Entry

A right of entry, also called a power of termination, is a future interest retained by the transferor following a fee simple subject to condition subsequent.

The important feature is that the property does not automatically return to the transferor when the condition is violated.

Instead, the transferor has the power to terminate the estate.

Consider:

“To Alice, but if the property is ever used for commercial purposes, O may terminate the estate.”

Alice receives a fee simple subject to condition subsequent.

If Alice violates the condition, O does not necessarily regain possession automatically.

O must exercise the retained right according to applicable law.

That retained interest is the right of entry.

---

11. Right of Entry vs. Possibility of Reverter

The distinction is particularly important.

Fee simple determinable

“To Alice so long as the property is used as a school.”

If the condition is violated, the estate terminates automatically.

O has a:

possibility of reverter.

Fee simple subject to condition subsequent

“To Alice, but if the property ceases to be used as a school, O may terminate the estate.”

If the condition is violated, the estate does not necessarily terminate automatically.

O has a:

right of entry.

The key question is:

Does the estate terminate automatically, or does the transferor have to act?

That question often determines the classification.

---

12. Remainders

A remainder is a future interest created in a transferee that becomes possessory upon the natural termination of a prior estate.

The classic example is:

“To Alice for life, then to Bob.”

Alice has a life estate.

Bob has a remainder.

When Alice dies, Bob becomes entitled to possession.

The important feature is that Bob’s interest waits for the earlier estate to end naturally.

---

13. The Basic Structure of a Remainder

A simple diagram helps:

O → Alice for life → then Bob.

At the beginning:

• Alice possesses the property.
• Bob does not possess the property.
• Bob nevertheless has a present future interest.

When Alice dies:

• Alice’s life estate ends.
• Bob’s remainder becomes possessory.

The transition is therefore:

Life estate → remainder becomes possessory estate

This is why the word “remainder” is used: the interest remains in the background until the prior estate ends.

---

14. Vested and Contingent Remainders

Remainders are traditionally divided into two major categories:

1. Vested remainders
2. Contingent remainders

This is one of the most important distinctions in future-interest doctrine.

---

15. Vested Remainder

A remainder is generally vested when it is created in an identifiable person and is not subject to a condition precedent.

Consider:

“To Alice for life, then to Bob.”

Bob is an identifiable person.

Nothing needs to happen before Bob’s interest exists other than the natural termination of Alice’s life estate.

Bob therefore has a vested remainder.

Importantly, vested does not mean possessory.

Bob’s interest is vested even though Alice currently possesses the property.

---

16. Contingent Remainder

A remainder is generally contingent when either:

1. it is given to an unascertained person; or
2. it is subject to a condition precedent.

Consider:

“To Alice for life, then to Alice’s first child to reach age 25.”

If Alice has no child yet, the person who will receive the property is not yet ascertainable.

The future interest may therefore be contingent.

Similarly:

“To Alice for life, then to Bob if Bob passes the bar examination.”

Bob is identified, but his right to take possession depends on a condition precedent.

That is traditionally a contingent remainder.

---

17. Condition Precedent

A condition precedent is an event that must occur before an interest becomes possessory or before the holder becomes entitled to take.

For example:

“To Alice for life, then to Bob if Bob survives Alice.”

Bob’s survival is a condition precedent.

If Bob does not survive Alice, Bob does not take under that provision.

The language and structure of the conveyance determine whether an event functions as a condition precedent or instead as a condition subsequent.

That distinction can have significant consequences.

---

18. Indefeasibly Vested Remainder

A vested remainder can be further classified.

An indefeasibly vested remainder is a vested remainder that is not subject to divestment or reduction.

Example:

“To Alice for life, then to Bob.”

Bob has an indefeasibly vested remainder.

If Alice dies, Bob takes possession.

There is no additional condition that could cause Bob’s interest to disappear.

---

19. Vested Remainder Subject to Complete Divestment

A vested remainder can exist while still being subject to a condition that could later eliminate it.

For example:

“To Alice for life, then to Bob, but if Bob ever becomes a convicted felon, to Carol.”

Bob’s remainder is initially vested because Bob is identified and no condition must occur before his interest exists.

But Bob’s interest can later be divested by the specified event.

The exact classification depends on the wording and applicable law.

This illustrates an important point:

Vested does not necessarily mean absolutely secure.

A future interest may be vested while remaining subject to later divestment.

---

20. Executory Interests

An executory interest is a future interest in a transferee that cuts short another estate before that estate would naturally terminate.

For example:

“To Alice, but if the property is ever used as a nightclub, then to Bob.”

Alice has an estate subject to a condition.

Bob has an executory interest.

If the triggering event occurs, Bob’s interest cuts short Alice’s estate.

The key concept is divestment.

A remainder waits for the natural termination of a prior estate.

An executory interest cuts short an existing estate.

---

21. Shifting and Springing Executory Interests

Executory interests are traditionally divided into two categories.

Shifting executory interest

A shifting executory interest transfers property from one transferee to another.

Example:

“To Alice, but if Alice stops using the property as her residence, then to Bob.”

Bob’s interest shifts the property from Alice to Bob.

Springing executory interest

A springing executory interest cuts short the transferor’s interest or follows a gap in possession.

Example:

“To Alice when she graduates from law school.”

If O currently owns the property and Alice has not yet graduated, Alice may have a future interest that will spring into possession upon the specified event.

The exact classification depends on the conveyance and jurisdiction.

---

22. Remainder vs. Executory Interest

This is one of the most important distinctions in property law.

Remainder	Executory interest
Follows a prior estate	Can cut short a prior estate
Becomes possessory when prior estate naturally ends	Becomes possessory upon a specified event
Does not traditionally divest the prior estate	Divests another estate
Example: “To A for life, then to B”	Example: “To A, but if X occurs, then to B”

A useful question is:

Does the future interest wait patiently for the prior estate to end, or does it cut that estate short?

If it waits for natural termination, think remainder.

If it cuts short another interest, think executory interest.

---

23. Reversion vs. Remainder

Another common source of confusion is the distinction between a reversion and a remainder.

Reversion

A reversion is retained by the transferor.

“O conveys to Alice for life.”

O has a reversion.

Remainder

A remainder is created in another transferee.

“O conveys to Alice for life, then to Bob.”

Bob has a remainder.

The simplest question is:

Who holds the future interest?

If the transferor retains it, it may be a reversion.

If a transferee receives it, it may be a remainder or executory interest.

---

24. The Five Major Future Interests

The overall structure can now be summarized:

Interest	Holder	Typical preceding estate	How it becomes possessory
Reversion	Transferor	Life estate, leasehold, or other lesser estate	Prior estate ends
Possibility of reverter	Transferor	Fee simple determinable	Condition occurs; estate ends automatically
Right of entry	Transferor	Fee simple subject to condition subsequent	Transferor exercises power after condition
Remainder	Transferee	Usually life estate or term of years	Prior estate naturally ends
Executory interest	Transferee	Estate subject to divestment or gap	Specified event occurs and cuts short another interest

This table provides the basic framework for analyzing future interests.

---

25. Why Future Interests Matter

Future interests are not merely technical classifications.

They determine who has legally enforceable rights in property.

For example, suppose a parent transfers property:

“To my daughter for life, then to my grandson.”

The daughter has present possession.

The grandson has a future interest.

The daughter therefore cannot necessarily treat the property as though she owned it in fee simple absolute.

Her rights may be limited by the grandson’s future interest.

This can affect:

• sales;
• mortgages;
• leases;
• development;
• estate planning;
• inheritance;
• partition;
• taxation;
• insurance;
• litigation.

---

26. Future Interests and Life Estates

Life estates provide one of the clearest contexts for understanding future interests.

Consider:

“To Alice for life, then to Bob.”

Alice:

• possesses the property;
• may use it;
• may exclude others;
• may receive rents and profits;
• must respect the rights of the future interest holder.

Bob:

• does not presently possess the property;
• has a future interest;
• may be able to transfer that interest;
• may become entitled to possession when Alice’s life estate ends.

This creates a relationship between the present estate holder and the future interest holder.

That relationship is particularly important under the doctrine of waste.

---

27. Waste and Future Interest Holders

A present possessory estate holder generally cannot use the property in a way that improperly destroys or substantially reduces the value of the future interest.

Suppose Alice holds a life estate and Bob holds the remainder.

Alice cannot necessarily:

• destroy valuable structures;
• remove valuable natural resources improperly;
• substantially alter the property;
• neglect the property in a way that causes serious deterioration.

The doctrine of waste protects future interests from destructive conduct by present possessors.

This demonstrates that a future interest can impose real legal constraints even before it becomes possessory.

---

28. Transferability of Future Interests

Many future interests are transferable, although the precise rules vary by jurisdiction and by type of interest.

Suppose Bob has:

“To Alice for life, then to Bob.”

Bob may potentially transfer his remainder to another person.

The transferee would generally receive Bob’s future interest rather than an immediate right to possess the property.

This means future interests can themselves become objects of transactions.

A lawyer therefore must not assume that the person currently occupying property is the only person whose consent matters.

---

29. Future Interests and Mortgages

Future interests can also affect financing.

Suppose:

Alice has a life estate.

Bob has a remainder.

Alice may have the ability to mortgage her own interest, depending on state law and the terms of the instrument.

But a mortgage of Alice’s life estate generally does not magically convert her interest into fee simple ownership.

When Alice’s life estate ends, the mortgagee’s rights may be affected accordingly.

This is another reason why identifying the estate and future interests correctly is essential.

---

30. Future Interests in Wills and Trusts

Future interests frequently appear in estate planning.

For example:

“I leave my house to my spouse for life, then to my children.”

The spouse receives a life estate.

The children receive future interests.

A similar structure can be created through a trust.

The objective may be to provide a person with present use of property while ensuring that the property eventually passes to another generation.

Future interests therefore provide a legal mechanism for controlling the timing of property ownership.

---

31. The Rule Against Perpetuities

One of the most famous and difficult doctrines involving future interests is the Rule Against Perpetuities.

In its traditional common-law form, the rule concerns certain future interests that may remain unresolved for too long.

The classic formulation is:

A future interest is invalid unless it must vest, if at all, no later than 21 years after the death of a life in being at the creation of the interest.

The rule is notoriously difficult because it focuses on possibility, not merely what actually happens.

A conveyance can therefore fail the rule even if the problematic event never occurs.

---

32. Why the Rule Against Perpetuities Exists

The policy behind the traditional rule is to prevent property owners from controlling property indefinitely into the future.

Imagine a person trying to dictate how land must be owned hundreds of years from now.

The law generally favors the ability of future generations to control property rather than allowing dead owners to impose permanent restrictions.

The Rule Against Perpetuities is therefore connected to a broader policy:

Property should not be tied up indefinitely by remote future interests.

Modern statutes and reforms have substantially modified the traditional common-law rule in many jurisdictions.

---

33. What Interests Can Raise Perpetuities Problems?

Historically, the Rule Against Perpetuities most famously applies to:

• contingent remainders;
• executory interests;
• vested remainders subject to open.

It generally does not apply in the same way to:

• indefeasibly vested remainders;
• reversions;
• possibilities of reverter;
• rights of entry.

However, modern statutory law can significantly modify these traditional rules.

Therefore, when analyzing a real transaction, the governing jurisdiction must always be identified.

---

34. The Rule Against Perpetuities: A Simple Example

Consider:

“To Alice for life, then to Alice’s first child to reach age 30.”

Suppose Alice has no children when the conveyance is made.

The question under the traditional rule is not:

“Will this interest actually vest within the permitted period?”

Instead, the question is:

“Is there any possibility that it might vest too remotely?”

That possibility can create a Rule Against Perpetuities problem.

This is one reason the doctrine is difficult: lawyers must analyze hypothetical possibilities rather than simply predicting the most likely outcome.

---

35. Modern Changes to the Rule

The traditional common-law Rule Against Perpetuities has been modified, abolished, or replaced in various jurisdictions.

Modern approaches can include:

• statutory waiting periods;
• “wait and see” doctrines;
• uniform statutory reforms;
• judicial reformation;
• extended perpetuities periods;
• abolition of the rule for certain types of interests.

Therefore, a law student should understand the traditional doctrine but should never assume that the common-law rule operates identically in every modern jurisdiction.

---

36. Future Interests and the Freedom to Transfer Property

Future interests raise a broader policy question:

How much control should a property owner have over the future?

An owner may want to ensure that property remains in the family.

Another owner may want to place restrictions on how land is used.

The law balances those wishes against policies favoring:

• alienability;
• productive use of property;
• marketability of title;
• certainty;
• freedom of future owners;
• avoidance of excessive restraints.

Future-interest doctrine is therefore part of a larger legal debate about the relationship between present ownership and future control.

---

37. Reading Future Interests in a Deed or Will

When analyzing a conveyance, begin with the exact language.

For example:

“To Alice for life, then to Bob.”

Ask:

1. What estate does Alice have?
2. Who has the future interest?
3. Is Bob identified?
4. Is Bob’s interest subject to a condition precedent?
5. Does the interest become possessory when Alice’s estate naturally ends?
6. Does some event instead cut short another estate?
7. Does the transferor retain any future interest?

The words used in the instrument often provide the starting point for classification.

---

38. A Practical Lawyer’s Analysis

When confronted with a future-interest problem, use a structured method.

Step 1: Identify the present estate

Determine who currently has possession and what estate that person holds.

Is it:

• fee simple absolute?
• life estate?
• leasehold?
• defeasible fee?

Step 2: Identify the future-interest holder

Ask who will potentially have the property later.

Is that person:

• the transferor?
• a named transferee?
• an unidentified class?
• someone who will take only if a condition occurs?

Step 3: Determine whether the interest waits or cuts short

If it waits for the prior estate to end naturally, it may be a remainder.

If it cuts short another estate, it may be an executory interest.

Step 4: Determine whether the transferor retained the interest

If the transferor retains the future interest, consider:

• reversion;
• possibility of reverter;
• right of entry.

Step 5: Identify conditions

Look for language such as:

• “if”
• “when”
• “unless”
• “so long as”
• “provided that”
• “but if.”

The legal significance depends on how the condition operates.

Step 6: Consider perpetuities

If the future interest is the type potentially subject to perpetuities rules, determine whether the applicable jurisdiction follows the traditional rule or a modern statutory approach.

Step 7: Consider transferability

Determine whether the future interest can be:

• sold;
• assigned;
• inherited;
• devised;
• released.

Step 8: Check the governing jurisdiction

Future-interest law is heavily shaped by state law.

A correct classification under one jurisdiction may not produce the same practical result under another.

---

39. Common Mistakes

Mistake 1: Thinking future interests are merely expectations

They are generally present legal interests, not simply hopes about future ownership.

Mistake 2: Assuming the person with possession owns everything

A life tenant may possess property while another person holds a remainder.

Mistake 3: Confusing a reversion with a remainder

A reversion is retained by the transferor.

A remainder is created in a transferee.

Mistake 4: Confusing a possibility of reverter with a right of entry

The central distinction is generally whether termination occurs automatically or requires action by the transferor.

Mistake 5: Calling every future interest a remainder

An interest that cuts short another estate is generally an executory interest rather than a remainder.

Mistake 6: Assuming vested means possessory

A vested remainder may exist for years before the holder obtains possession.

Mistake 7: Ignoring conditions

Small differences in wording can produce substantially different legal consequences.

Mistake 8: Applying the traditional Rule Against Perpetuities mechanically

Modern jurisdictions differ considerably in their treatment of perpetuities.

---

40. Future Interests vs. Present Possessory Interests

Feature	Present possessory estate	Future interest
Present right to possession	Yes	Generally no
Legal interest exists now	Yes	Yes
May become possessory later	Already possessory	Yes
Example	Life estate	Remainder
Typical function	Current ownership/use	Future ownership/control

The critical distinction is therefore not whether the interest legally exists.

Both interests exist.

The distinction is when the right to possession is exercisable.

---

41. Future Interests in a Single Example

Consider the following series:

O conveys Blackacre “to Alice for life, then to Bob, but if Bob ever uses the property for commercial purposes, then to Carol.”

The arrangement potentially involves several interests.

Alice has:

a life estate.

Bob has:

a remainder, subject to the specified limitation depending on the precise drafting.

Carol may have:

a future interest that can divest Bob, potentially an executory interest.

O may retain:

a reversion, depending on whether the conveyance exhausts the transferred interests and how the instrument is structured.

The exact legal classification requires careful reading of the entire conveyance.

This illustrates why future-interest questions often require more than simply identifying individual words.

---

42. Future Interests and Marketable Title

Future interests can create complications when property is sold.

Suppose:

Alice has a life estate.

Bob has a remainder.

A buyer dealing only with Alice may not acquire complete ownership of the property.

The buyer must determine:

• who holds the present estate;
• who holds future interests;
• whether those interests are transferable;
• whether all necessary parties have executed the transaction;
• whether the title can be insured;
• whether any restrictions affect the property.

This is why title examination is particularly important when estates have been divided over time.

---

43. Why Future Interests Are Difficult

Future interests are difficult because several different legal concepts operate simultaneously.

A lawyer may need to determine:

1. what estate exists now;
2. who has possession;
3. who has a future interest;
4. whether that future interest is vested or contingent;
5. whether a condition is precedent or subsequent;
6. whether an interest can divest another;
7. whether the transferor retained an interest;
8. whether the Rule Against Perpetuities applies;
9. whether a statute modifies common-law rules.

The challenge is therefore not merely memorizing definitions.

It is learning to read the structure of the conveyance.

---

44. Key Takeaways

• A remainder is a future interest created in a transferee that follows a prior estate and becomes possessory when that estate naturally ends.
• A vested remainder generally has an identifiable holder and is not subject to a condition precedent.
• A contingent remainder generally depends on an uncertain event or an unascertained taker.
• An executory interest cuts short another estate or otherwise operates outside the traditional remainder structure.
• Future interests can affect sales, mortgages, leases, inheritance, estate planning, and title.
• The Rule Against Perpetuities limits certain future interests under traditional common law, although modern jurisdictions vary substantially.

45. Frequently Asked Questions

What is a future interest in property law?

A future interest is a present legal interest in property that does not currently give the holder possession but may give the holder a right to possess the property later.

What are the five major future interests?

The traditional categories are reversion, possibility of reverter, right of entry, remainder, and executory interest.

What is the difference between a remainder and a reversion?

A reversion is retained by the transferor. A remainder is created in a transferee.

What is the difference between a remainder and an executory interest?

A remainder generally becomes possessory when a prior estate naturally ends. An executory interest can cut short another estate.

What is a vested remainder?

A vested remainder is generally a remainder held by an identifiable person and not subject to a condition precedent.

What is a contingent remainder?

A contingent remainder generally depends on a condition precedent or is held by an unascertained person.

Can future interests be transferred?

Many future interests can be transferred, inherited, or otherwise dealt with as property interests, although the rules vary by jurisdiction and by type of interest.

Does a future interest mean the holder owns the property now?

Not necessarily in the ordinary possessory sense. A future-interest holder has a legally recognized interest now, but generally does not have the present right to possess the property.

What is the Rule Against Perpetuities?

The traditional Rule Against Perpetuities limits certain future interests that might remain unresolved for too long. Modern statutes have substantially changed the rule in many jurisdictions.

Why do future interests matter?

They determine who may have rights in property after a present estate ends and can affect transactions, inheritance, estate planning, development, title, and litigation.

Conclusion

Future interests reveal one of the most important features of property law: ownership can be divided across time as well as among people.

A person may possess property today while another person holds a legally protected interest in possessing it tomorrow. That division can be created through a life estate, a defeasible fee, a will, a trust, or another conveyance.

The central categories provide a framework for understanding these arrangements. A reversion, possibility of reverter, or right of entry generally represents an interest retained by the transferor. A remainder or executory interest generally represents a future interest created in another person.

Once these distinctions are understood, more complicated areas of property law become easier to analyze. Estates, wills, trusts, conveyancing, title examination, co-ownership, and estate planning all depend on the ability to identify who has the right to possession now—and who may have that right in the future.

Future interests therefore are not merely technical remnants of old property law. They are a fundamental mechanism through which the law organizes the present ownership, future control, and eventual transfer of property.
