A specific item of property that is left to a named beneficiary under a will. If the person who made the will no longer owns the property when he dies, the bequest fails. In other words, the beneficiary cannot substitute a similar item in the estate. Example: If John leaves his 1954 Mercedes to Patti, and when John dies the 1954 Mercedes is long gone, Patti doesn't receive John's current car or the cash equivalent of the Mercedes. See ademption.

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.

A formal written request made to a court, asking for an order or ruling on a particular matter. For example, if you want to be appointed conservator for an elderly relative, you must file a petition with a court. See also complaint.

An outdated term for a female administrator -- the person appointed by a court to handle probate on behalf of someone who died without a will. Now, whether male or female, this person is called the administrator.

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.

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.
