Perpetuities and Accumulations Act 2009 Explanatory Notes

The rule against perpetuities

The common law rule

5.The rule against perpetuities was developed by the courts at the end of the seventeenth century. The rule restricts the time period within which future interests in property must vest. The perpetuity period is the length of a life or lives in being, plus 21 years. A life in being means a life in being at the time of the disposition. Lives in being may be expressly specified in the instrument by which the disposition is made (for example, by using a royal lives clause like “the lineal descendants of Queen Victoria living at the time of my death”). If no lives are specified, the lives in being will be the persons whose lives are connected with the date of vesting of the disposition. So, for example, in a gift to “the first of A’s great-great-grandchildren to play chess with B”, where no such great-great-grandchildren have been born at the time of the gift, B’s is the measuring life – the life in being.

6.The application of this common law rule, which still applies without statutory modifications to dispositions made before 16 July 1964, can be demonstrated by an example. X makes a gift of property in a will to the first of A’s children to attain the age of 21. On X’s death the will takes effect. It purports to create a property interest for the first of A’s children to meet the condition specified. The perpetuity period will begin to run on the date of X’s death and will continue for the remainder of A’s life plus 21 years. If one looks at the matter as at the date of X’s death, it is certain that any child of A will attain 21 (if at all) within 21 years of A’s death, since A cannot produce more children once dead. The gift therefore does not infringe the rule against perpetuities.

7.On the other hand, a gift in X’s will to the first of A’s children to become a doctor would be void at common law, assuming none of them is already a doctor. It is not certain, at the date of X’s death, that any child of A will become a doctor (if at all) within 21 years of A’s death. It is certainly possible that a child of A may become a doctor within that time. However, looked at from the date of X’s death, it is possible that the first child of A to become a doctor may not do so until after the perpetuity period has expired. Hence the gift would be void at common law.

8.The rule against perpetuities was originally developed in the context of family settlements to curtail control by one generation of the use of property by future generations. However, the rule was later extended to other types of property rights such as future easements, options to purchase and some rights of pre-emption.

Perpetuities and Accumulations Act 1964

9.The Perpetuities and Accumulations Act 1964 (“the 1964 Act”), which came into force on 16 July 1964, modified the operation of the common law rule. The 1964 Act, which was based on the 1956 report of the Law Reform Committee (Fourth Report, The rule against perpetuities (1956) Cmnd 18), contained three key reforms to the common law rule. These reforms apply in relation to dispositions made on or after 16 July 1964.

10.First, it allowed settlors to specify a fixed perpetuity period of up to 80 years instead of having to rely on the common law period of a life in being plus 21 years.

11.Second, it introduced the principle of “wait and see”. This means that, where an interest in property could possibly vest outside the perpetuity period and so would be void at common law, it is permissible to “wait and see” whether the property will in fact vest within the perpetuity period. Only when it becomes clear that the gift cannot so vest will the gift be void. So in the example above (at paragraph 7), the gift would be void only if no child became a doctor within 21 years of A’s death.

12.Third, the 1964 Act introduced a number of other “gift-saving” devices. Class closing rules are one such device which allow a gift to be saved by the exclusion of a beneficiary whose inclusion would invalidate a gift. Another ensures that a gift will not be invalid automatically just because it follows a previous interest which violates the rule.
