Most students view the Rule against Perpetuities as the most difficult rule in law school. Moreover, the Rule is still covered on MBE for Property and MEE for Wills and Trusts and yet few student-centered resources exist. The Little Book on Perpetuities fills this gap. An ideal subject for self-study, this guide covers all key parts of the Rule, including problems for self-testing. It presents the Rule in its historical context but in a fun, engaging, and accessible way that is simple and clear for students to use. It can be used for Property classes, as well as Wills & Trusts and can supplement a casebook or be used as a separate, self-continued unit. Coverage includes: the common-law Rule and all the famous classics traps; modern statutory reforms, including the new generations-based rule by the Restatement Third of Property; recent efforts by some states to abolish the Rule; and the history and policies of the Rule.
