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.

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.

A person who makes investments. An investor may act either for herself or on behalf of others. A stock broker or mutual fund manager, for instance, makes investments for others who have entrusted her with their money.

An organization, institution or being that has its own existence for legal or tax purposes. An entity is often an organization with an existence separate from its individual members--for example, a corporation, partnership, trust, estate or government agency. The entity is treated like a person; it can function legally, be sued, and make decisions through agents.

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.

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.

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 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.

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.
