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 inability, as determined by a court, to handle one's own personal or financial affairs. A court may declare that a person is incompetent after a hearing at which the person is present and/or represented by an attorney. A finding of incompetence may lead to the appointment of a conservator to manage the person's affairs. Also known as 'incompetency.'

A procedure under state law that gives a surviving spouse the right to demand a certain share (usually one-third to one-half) of the deceased spouse's property. The surviving spouse can take that share instead of accepting whatever he or she inherited through the deceased spouse's will. If the surviving spouse decides to take the statutory share, it's called 'taking against the will.' Dower and curtesy is another name for the same legal process.

A type of trust for wealthy married couples that allows a surviving spouse to postpone estate taxes. A QTIP trust allows the surviving spouse to make use of the trust property tax-free. Taxes are deferred until the surviving spouse dies and the trust property is received by the final trust beneficiaries, who were named by the first spouse to die.

The failure of a bequest of property in a will. The gift fails (is 'adeemed') because the person who made the will no longer owns the property when he or she dies. Often this happens because the property has been sold, destroyed or given away to someone other than the beneficiary named in the will. A bequest may also be adeemed when the will maker, while still living, gives the property to the intended beneficiary (called 'ademption by satisfaction'). When a bequest is adeemed, the beneficiary named in the will is out of luck; he or she doesn't get cash or a different item of property to replace the one that was described in the will. For example, Mark writes in his will, 'I leave to Rob the family vehicle,' but then trades in his car in for a jet ski. When Mark dies, Rob will receive nothing. Frustrated beneficiaries may challenge an ademption in court, especially if the property was not clearly identified in the first place.

The portion of a deceased person's estate that a spouse is entitled to claim under state law. The statutory share is usually one-third or one-half of the deceased spouse's property, but in some states the exact amount of the spouse's share depends on whether or not the couple has young children and, in a few states, on how long the couple was married. In most states, if the deceased spouse left a will, the surviving spouse must choose either what the will provides or the statutory share. Sometimes the statutory share is known by its more arcane legal name, dower and curtesy, or as a forced or elective share.

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.
