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.

A trust designed to save on estate tax. The trust principal is preserved for the trust maker's grandchildren, with his or her children receiving only income from the trust. Because the children (the middle generation) never legally own the property, it isn't subject to estate tax at their death. See generation-skipping transfer tax.

A condensed version of a living trust document, which leaves out details of what is in the trust and the identity of the beneficiaries. You can show an abstract of trust to a financial organization or other institution to prove that you have established a valid living trust, without revealing specifics that you want to keep private. In some states, this document is called a 'certification of trust.'

Under a will, the most common method of determining what share of property each beneficiary gets when one of the beneficiaries dies before the willmaker, leaving 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 capita, Julie and the two grandchildren will each take a third. If, on the other hand, 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).

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.

To deliberately prevent someone from inheriting something. This is usually done by a provision in a will stating that someone who would ordinarily inherit property -- a close family member, for example -- should not receive it. In most states, you cannot completely disinherit your spouse; a surviving spouse has the right to claim a portion (usually one-third to one-half) of the deceased spouse's estate. With a few exceptions, however, you can expressly disinherit children.

Convincing a probate court that a document is truly the deceased person's will. Usually this is a simple formality that the executor or administrator easily satisfies by showing that the will was signed and dated by the deceased person in front of two or more witnesses. When the will is holographic -- that is, completely handwritten by the deceased and not witnessed, it is still valid in many states if the executor can produce relatives and friends to testify that the handwriting is that of the deceased.
