An exceedingly complex legal doctrine that limits the amount of time that property can be controlled after death by a person's instructions in a will. For example, a person would not be allowed to leave property to her husband for his life, then to her children for their lives, then to her grandchildren. The gift would potentially go to the grandchildren at a point too remote in time.

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.

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.

In general terms, an augmented estate consists of property owned by both a deceased person and his or her spouse. The concept of the augmented estate is used only in some states. Its value is calculated only if a surviving spouse declines whatever he or she was left by will and instead claims a share of the deceased spouse's estate. (This is called taking against the will.) The amount of this 'statutory share' or 'elective share' depends on state law.

The distribution of a deceased person's property by any means other than probate. Many types of property pass free of probate, including property left to a surviving spouse and property left outside of a will through probate-avoidance methods such as pay-on-death designations, joint tenancy ownership, living trusts and life insurance. Property that avoids probate is sometimes described as the 'nonprobate estate.' Nonprobate distribution may also occur if the deceased person leaves an invalid will. In that case, property will pass according to the particular state's laws of intestate succession.

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.
