Rule Against Perpetuities
The legal concept forbidding a testator from leaving portions of his/her estate unvested in a beneficiary after a certain number of years. The rule against perpetuities disallows an estate from holding back certain assets for descendants who will not be born for several generations. While it is part of the common law, not all jurisdictions have a rule against perpetuities. Among those that do have it, the rule begins to apply between 20 and 90 years after a person's death. See also: Rule against accumulations.
