Simplifying the Rule Against Perpetuities: A Modern Guide

Meta Overview: The Dead Hand Principle

The Rule Against Perpetuities (RAP) is a centuries-old property law concept designed to prevent landowners from controlling the ownership of their assets for an unreasonably long time after their death—a concept often called the “dead hand” of the grantor. It ensures property remains alienable and transferable, rather than being tied up by remote future conditions.

For individuals involved in estate planning, creating complex trusts, or drafting intricate wills, few legal concepts are as infamous or as potentially destructive to a disposition plan as the Rule Against Perpetuities. This rule, though notorious for its technicality, rests on a simple, foundational principle: property must remain marketable and cannot be indefinitely controlled by the deceased. Understanding the rule—and its modern reforms—is essential for securing your legacy and ensuring your intentions are upheld.

What is the Common Law Rule Against Perpetuities (RAP)?

The classical, common-law formulation of the Rule Against Perpetuities is best summarized by this maxim: “No interest is good unless it must vest, if at all, not later than twenty-one years after some life in being at the creation of the interest.”.

In essence, the rule provides a strict timeline for when a future property interest must become fixed, or “vested,” in an ascertainable person. If there is any possibility—no matter how unlikely—that the interest could vest beyond that period, the entire gift is voided from the start.

★ Legal Expert Tip: Understanding the Components

Future Interest: A right to property that does not take possession until some point in the future. The RAP primarily applies to contingent remainders and executory interests.
Vesting: The moment a property interest becomes a non-contingent, absolute right belonging to an identified individual.
Life in Being: An identifiable person (or a class of people) who is alive when the legal instrument (will or trust) takes effect. This person serves as the “measuring life” for the perpetuity period.
The Period: The interest must vest within the lifetime of the measuring life, plus an additional 21 years (plus a period of gestation).

The Policy Behind the Rule: Alienability of Property

The core justification for the Rule Against Perpetuities is economic and social: to promote the free exchange (or “alienability”) of property. Historically, aristocratic families used property restrictions to keep vast estates intact for generations. This practice restricts marketability, as few people would buy land clouded by contingent future ownership claims that might not be resolved for centuries. The rule aims to strike a balance between allowing a property owner to exercise control (testamentary freedom) and ensuring future generations have the ability to buy, sell, and develop the property as they see fit.

The Traps of the Common Law: Fanciful Possibilities

What makes the common law RAP so challenging is its reliance on possibilities, not probabilities or actual events. If a single, far-fetched scenario exists at the time the instrument is created that could delay vesting beyond the perpetuity period, the interest is immediately void.

The Infamous Examples

The Fertile Octogenarian: The common law presumes that a person is capable of having a child at any age. A gift conditioned on the birth of a child to a very elderly woman, followed by a remainder interest to that child’s child, could be voided because the measuring life (the mother) might die, and her hypothetical new child could live longer than 21 years, delaying the vesting of the remainder. Modern reforms have largely eliminated this presumption for women over a certain age (e.g., 55).
The Unborn Widow: This rule voids a gift to a person’s “widow” followed by a remainder to the person’s children, because the “widow” could be someone who was not alive when the interest was created, thus not a measuring life.

Case Box: A Hypothetical Violation

A testator leaves a large estate in trust “to my son, Alex, for life, and upon his death, to such of his children who reach the age of 25.” When the will is created, Alex is alive and has two children, aged 10 and 15. The gift to the children is invalid under common law RAP. Why? Because Alex could have another child (let’s call him ‘Z’) after the will takes effect, and then Alex could die. Child Z would have to wait until age 25 to vest the interest. Since Alex is the measuring life, Child Z turning 25 could happen more than 21 years after Alex’s death, violating the rule.

The Modern Era: Reform and the Death of the Common Law RAP

The inherent harshness and complexity of the common-law rule led to widespread legislative and judicial reform across the United States. Today, fewer jurisdictions strictly adhere to the original common-law RAP. Modern approaches aim to honor the creator’s intent using more flexible methods:

1. The Uniform Statutory Rule Against Perpetuities (USRAP)

Over half of U.S. states have adopted the USRAP, which introduced two primary changes:

Wait-and-See: Instead of voiding a gift based on a remote possibility, courts “wait and see” if the interest actually vests within the permissible period.
90-Year Period: The USRAP creates an alternative, non-rebuttable vesting period of 90 years. If the interest fails to vest within the life in being plus 21 years, it still has up to 90 years from its creation to vest before being deemed invalid.

2. Dynasty Trusts and Abolition

A significant number of states, seeking to attract wealth management business, have either abolished the Rule Against Perpetuities entirely for trusts or extended the vesting period dramatically to allow for “dynasty trusts”. This allows families to shield assets from transfer taxes and keep wealth locked in a trust structure for multiple generations, often for periods of 150, 500, 1,000 years, or even in perpetuity. This trend reflects a modern shift favoring multi-generational wealth preservation over the strict historical priority of property alienability.

Summary: Key Takeaways for Estate Planning

The common-law Rule Against Perpetuities was created to prevent indefinite control of property by the dead, requiring future interests to vest within a “life in being plus 21 years.”
Violating the rule can completely void a portion of a will or trust, potentially frustrating a testator’s entire estate plan.
Modern legal reforms, such as the Uniform Statutory Rule Against Perpetuities (USRAP), have replaced the rigid common-law rule in many states with a more flexible 90-year “wait-and-see” period.
Many jurisdictions have further modified or abolished the rule for trusts, allowing for long-term “dynasty trusts” that can last for centuries or forever.
Consulting with a qualified Legal Expert is crucial to ensure that any complex transfer or trust instrument includes a “savings clause” designed to comply with the specific perpetuity rule of your governing jurisdiction.

The Bottom Line on Future Interests

The Rule Against Perpetuities remains a critical concept in property and trust law, acting as a technical guardrail against indefinite wealth control. While the common law rule has largely been replaced by more sensible statutory reforms (like the USRAP’s 90-year period and the allowance of long-term dynasty trusts), its core principle—that future interests must eventually vest—is alive and well. Always rely on a Legal Expert when drafting documents that create remote future interests to avoid inadvertent invalidation.

Frequently Asked Questions (FAQ)

Q1: Does the Rule Against Perpetuities apply to my simple will?: A: For simple, direct bequests (e.g., “I leave my house to my child”), no. The rule only applies to future interests that are contingent on an uncertain event and may not vest until long after your death. Most simple estate plans are not affected.
Q2: What is the “wait-and-see” approach?: A: The wait-and-see approach, adopted by the Uniform Statutory Rule Against Perpetuities (USRAP), provides a second chance for an interest. Instead of invalidating a future interest based on a remote possibility of a violation, a court will “wait” up to 90 years to see if the interest actually vests within that time.
Q3: What happens if a provision in my trust violates the Rule Against Perpetuities?: A: The consequence is severe: the violating interest is typically voided (stricken) from the instrument as if it was never written. In many states with reform statutes (like USRAP), a court may attempt to “reform” the language (a doctrine called cy pres) to most closely match the original intent while still complying with the perpetuity period.
Q4: How has the rise of “Dynasty Trusts” impacted the rule?: A: The rise of dynasty trusts—long-term, tax-advantaged trusts—has led many states to abolish or significantly lengthen their perpetuity periods (e.g., to 360, 500, or 1,000 years) or allow trusts to last indefinitely. This makes these states highly competitive for wealth management and generational asset planning.
