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 document given to an executor by the probate court, authorizing the executor to settle the estate according to either a will or the state's intestate succession laws.

The distribution of a deceased person's property by any means other than probate. Many types of property pass free of probate, including property left to a surviving spouse and property left outside of a will through probate-avoidance methods such as pay-on-death designations, joint tenancy ownership, living trusts and life insurance. Property that avoids probate is sometimes described as the 'nonprobate estate.' Nonprobate distribution may also occur if the deceased person leaves an invalid will. In that case, property will pass according to the particular state's laws of intestate succession.

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.
