Under a will, the failure of a gift of property. A gift lapses when the beneficiary dies before the person who made the will, and no alternate has been named. Some states have anti-lapse statutes, which prevent gifts to relatives of the deceased person from lapsing unless the relative has no heirs of his or her own. A lapsed gift becomes part of the residuary estate.

A child or spouse who is not mentioned in a will and whom the court believes was accidentally overlooked by the person who made the will. For example, a child born or adopted after the will is made may be deemed a pretermitted heir. If the court determines that an heir was accidentally omitted, that heir is entitled to receive the same share of the estate as she would have if the deceased had died without a will. A pretermitted heir is sometimes called an 'omitted heir.'

Under a will, a method of determining who inherits property when a joint beneficiary has died before the willmaker, leaving living children of his or her own. For example, Fred leaves his house jointly to his son Alan and his daughter Julie. But Alan dies before Fred, leaving two young children. If Fred's will states that heirs of a deceased beneficiary are to receive the property 'per stirpes,' Julie will receive one-half of the property, and Alan's two children will share his half in equal shares (through Alan by right of representation). If, on the other hand, Fred's will states that the property is to be divided per capita, Julie and the two grandchildren will each take a third.

A complete listing of all property owned by a deceased person at the time of death. The inventory is filed with the court during probate. The executor or administrator of the estate is responsible for making and filing the inventory.

An outdated term for a female administrator -- the person appointed by a court to handle probate on behalf of someone who died without a will. Now, whether male or female, this person is called the administrator.

A bypass trust funded with an amount no larger than the personal federal estate tax exemption in the year of death. If the trust grantor leaves property worth more than that amount, it usually goes to the surviving spouse. The trust property passes free from estate tax because of the personal exemption, and the rest is shielded from tax under the surviving spouse's marital deduction.

A will that is created in a way that allows a probate court to easily accept it as the true will of the person who has died. In most states, a will is self-proving when two witnesses sign under penalty of perjury that they observed the willmaker sign it and that he told them it was his will. If no one contests the validity of the will, the probate court will accept the will without hearing the testimony of the witnesses or other evidence. To make a self-proving will in other states, the willmaker and one or more witnesses must sign an affidavit (sworn statement) before a notary public certifying that the will is genuine and that all willmaking formalities have been observed.
