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 trust designed to save on estate tax. The trust principal is preserved for the trust maker's grandchildren, with his or her children receiving only income from the trust. Because the children (the middle generation) never legally own the property, it isn't subject to estate tax at their death. See generation-skipping transfer tax.

A procedure under state law that gives a surviving spouse the right to demand a certain share (usually one-third to one-half) of the deceased spouse's property. The surviving spouse can take that share instead of accepting whatever he or she inherited through the deceased spouse's will. If the surviving spouse decides to take the statutory share, it's called 'taking against the will.' Dower and curtesy is another name for the same legal process.

A trust that allows couples to reduce or avoid estate taxes. Each spouse puts his or her property in an AB trust. When the first spouse dies, his or her half of the property goes to the beneficiaries named in the trust -- commonly, the grown children of the couple -- with the crucial condition that the surviving spouse has the right to use the property for life and is entitled to any income it generates. The surviving spouse may even be allowed to spend principal in certain circumstances. When the surviving spouse dies, the property passes to the trust beneficiaries. It is not considered part of the second spouse's estate for estate tax purposes. Using this kind of trust keeps the second spouse's taxable estate half the size it would be if the property were left directly to the spouse. This type of trust is also known as a bypass or credit shelter trust.

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.
