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 method by which property is distributed when a person dies without a valid will. Each state's law provides that the property be distributed to the closest surviving relatives. In most states, the surviving spouse, children, parents, siblings, nieces and nephews, and next of kin inherit, in that order.

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.'
