A type of trust for wealthy married couples that allows a surviving spouse to postpone estate taxes. A QTIP trust allows the surviving spouse to make use of the trust property tax-free. Taxes are deferred until the surviving spouse dies and the trust property is received by the final trust beneficiaries, who were named by the first spouse to die.

The portion of a deceased person's estate that a spouse is entitled to claim under state law. The statutory share is usually one-third or one-half of the deceased spouse's property, but in some states the exact amount of the spouse's share depends on whether or not the couple has young children and, in a few states, on how long the couple was married. In most states, if the deceased spouse left a will, the surviving spouse must choose either what the will provides or the statutory share. Sometimes the statutory share is known by its more arcane legal name, dower and curtesy, or as a forced or elective share.

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 defendant's court papers that seek to reverse the thrust of the lawsuit by claiming that it was the plaintiff -- not the defendant -- who committed legal wrongs, and that as a result it is the defendant who is entitled to money damages or other relief. Usually filed as part of the defendant's answer -- which also denies plaintiff's claims -- a counterclaim is commonly but not always based on the same events that form the basis of the plaintiff's complaint. For example, a defendant in an auto accident lawsuit might file a counterclaim alleging that it was really the plaintiff who caused the accident. In some states, the counterclaim has been replaced by a similar legal pleading called a cross-complaint. In other states and in federal court, where counterclaims are still used, a defendant must file any counterclaim that stems from the same events covered by the plaintiff's complaint or forever lose the right to do so. In still other states where counterclaims are used, they are not mandatory, meaning a defendant is free to raise a claim that it was really the plaintiff who was at fault either in a counterclaim or later as part of a separate lawsuit.

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.

The inability, as determined by a court, to handle one's own personal or financial affairs. A court may declare that a person is incompetent after a hearing at which the person is present and/or represented by an attorney. A finding of incompetence may lead to the appointment of a conservator to manage the person's affairs. Also known as 'incompetency.'
