Ademption

n. case in which property listed in a will cannot be given to a beneficiary because it did not belong to the deceased at the time of death (Law)

Ademption is a term used in the law of wills to determine what happens when property bequested under a will is no longer in the testator's estate when the testator dies. For devises of specific items of property, called specific gifts the property is adeemed, and the gift fails. If, for example, the will bequeathed the testator's car to a specific person, but the testator owned no car at the time of his death, then the gift would have been adeemed and the beneficiary would receive no gift at all.
