An organization, institution or being that has its own existence for legal or tax purposes. An entity is often an organization with an existence separate from its individual members--for example, a corporation, partnership, trust, estate or government agency. The entity is treated like a person; it can function legally, be sued, and make decisions through agents.

Under a will, the failure of a gift of property. A gift lapses when the beneficiary dies before the person who made the will, and no alternate has been named. Some states have anti-lapse statutes, which prevent gifts to relatives of the deceased person from lapsing unless the relative has no heirs of his or her own. A lapsed gift becomes part of the residuary estate.

In trademark law, a mark that is not inherently distinctive becomes protected after developing a 'secondary meaning': great public recognition through long use and exposure in the marketplace. For example, though first names are not generally considered inherently distinctive, Ben & Jerry's Ice Cream has become so well known that it is now entitled to maximum trademark protection.

Convincing a probate court that a document is truly the deceased person's will. Usually this is a simple formality that the executor or administrator easily satisfies by showing that the will was signed and dated by the deceased person in front of two or more witnesses. When the will is holographic -- that is, completely handwritten by the deceased and not witnessed, it is still valid in many states if the executor can produce relatives and friends to testify that the handwriting is that of the deceased.

A child or spouse who is not mentioned in a will and whom the court believes was accidentally overlooked by the person who made the will. For example, a child born or adopted after the will is made may be deemed a pretermitted heir. If the court determines that an heir was accidentally omitted, that heir is entitled to receive the same share of the estate as she would have if the deceased had died without a will. A pretermitted heir is sometimes called an 'omitted heir.'

A federal law passed to protect pension rights. ERISA: sets minimum standards for pension plans, guaranteeing that pension rights cannot be unfairly denied to or taken from a worker provides some protection for workers in the event certain types of pension plans cannot pay the benefits to which workers are entitled, and requires that employers provide full and clear information about employees' pension rights, including the way pension benefits accumulate, how the company invests pension funds, and when and how pension benefits can be collected.

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.
