In property law of the United Kingdom and the United States and other common law countries, a remainder is a future interest given to a person (who is referred to as the transferee or remainderman) that is capable of becoming possessory upon the natural end of a prior estate created by the same instrument. Thus, the prior estate must be one that is capable of ending naturally, for example upon the expiration of a term of years or the death of a life tenant. A future interest following a fee simple absolute cannot be a remainder because of the preceding infinite duration. For example: A person, , conveys (gives) a piece of real property called "Blackacre" "to for life, and then to and her heirs". receives a life estate in Blackacre. holds a remainder, which can become possessory when the prior estate naturally terminates ('s death).

For example conveys to " for life, then to and 's heirs." has an indefeasibly vested remainder, certain to become possessory upon termination of 's life estate (when dies). or 's heirs will clearly be entitled to possession upon ’s death. Subject to open Vested remainders subject to open are rare. The most common example is " conveys Blackacre to for life, remainder to the children of in fee simple, and has two children and ". Both and are ascertainable people, but both might die before , so the vested remainder is not certain to become possessory and thus the remainder is defeasible. The most important distinction between vested remainders subject to open and indefeasibly vested remainders are that vested subject to open remainders can be subject to language in the conveyance which can enlarge the
