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.

A person who makes investments. An investor may act either for herself or on behalf of others. A stock broker or mutual fund manager, for instance, makes investments for others who have entrusted her with their money.

A will that is created in a way that allows a probate court to easily accept it as the true will of the person who has died. In most states, a will is self-proving when two witnesses sign under penalty of perjury that they observed the willmaker sign it and that he told them it was his will. If no one contests the validity of the will, the probate court will accept the will without hearing the testimony of the witnesses or other evidence. To make a self-proving will in other states, the willmaker and one or more witnesses must sign an affidavit (sworn statement) before a notary public certifying that the will is genuine and that all willmaking formalities have been observed.

Taxes imposed by the state or federal government on property as it passes from the dead to the living. All property you own, whatever the form of ownership, and whether or not it goes through probate after your death, is subject to federal estate tax. Currently, however, federal estate tax is due only if your property is worth at least $2 million when you die. The estate tax is scheduled to be repealed for one year, in 2010, but Congress will probably make the repeal (or a very high exempt amount) permanent. Any property left to a surviving spouse (if he or she is a U.S. citizen) or a tax-exempt charity is exempt from federal estate taxes. Many states now also impose their own estate taxes or inheritance taxes.

A document in which you specify what is to be done with your property when you die and name your executor. You can also use your will to name a guardian for your young children.

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.
