The legal authority to decide who will receive someone else's property, usually property held in a trust. Most trustees can distribute the income from a trust only according to the terms of the trust, but a trustee with a power of appointment can choose the beneficiaries, sometimes from a list of candidates specified by the grantor. For example, Karin creates a trust with power of appointment to benefit either the local art museum, symphony, library or park, depending on the trustee's assessment of need.

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.

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 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.
