Latin for 'the body' of the trust. This term refers to all the property transferred to a trust. For example, if a trust is established (funded) with $250,000, that money is the corpus. Sometimes the trust corpus is known as the 'res,' a Latin word meaning 'thing.'

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 formal written request made to a court, asking for an order or ruling on a particular matter. For example, if you want to be appointed conservator for an elderly relative, you must file a petition with a court. See also complaint.

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 In some states, the counterclaim has been replaced by a similar legal pleading called a cross-complaint.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.
