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.

All property other than land and buildings attached to land. Cars, bank accounts, wages, securities, a small business, furniture, insurance policies, jewelry, patents, pets and season baseball tickets are all examples of personal property. Personal property may also be called personal effects, movable property, goods and chattel, and personalty. Compare real estate.

Under a trust, the situation that occurs when the sole trustee and the sole beneficiary are the same person or institution. Then, there's no longer the separation between the trustee's legal ownership of trust property from the beneficiary's interest. The trust 'merges' and ceases to exist.
