The Rule Against Perpetuities famously requires that a future interest must vest, if at all, within 21 years after the death of some 'life in being' at the creation of the interest. Yet, many modern trusts are designed to last for hundreds of years, often by using perpetual trust jurisdictions that have abolished or modified the rule.
