A person who receives any property by a will or trust that is not specifically left to another designated beneficiary. For example, if Antonio makes a will leaving his home to Edwina and the remainder of his property to Elmo, then Elmo is the residuary beneficiary.

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 bypass trust funded with an amount no larger than the personal federal estate tax exemption in the year of death. If the trust grantor leaves property worth more than that amount, it usually goes to the surviving spouse. The trust property passes free from estate tax because of the personal exemption, and the rest is shielded from tax under the surviving spouse's marital deduction.

A probate proceeding conducted in a different state from the one the deceased person resided in at the time of death. Usually, ancillary probate proceedings are necessary if the deceased person owned real estate in another state.

A trust in which the income is retained and not paid out to beneficiaries until certain conditions are met. For example, if Uncle Pierre creates a trust for Nick's benefit but stipulates that Nick will not get a penny until he gets a Ph.D. in French; Nick is the beneficiary of an accumulation trust.

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.
