A rule that allows you to cancel a contract within a specified time period (typically three days) after signing it. Federal cooling-off rules apply this three-day grace period to sales made door-to-door and anywhere other than a seller's normal place of business, such as at a trade show. Another federal cooling-off rule lets you cancel a home improvement loan or second mortgage within three days of signing. Various states have cooling-off rules that sometimes apply even longer cancellation periods to specific types of sales, such as dancing lessons and timeshares.

A legal doctrine that requires landlords to offer and maintain livable premises for their tenants. If a landlord fails to provide habitable housing, tenants in most states may legally withhold rent or take other measures, including hiring someone to fix the problem or moving out. See constructive eviction.

A non-U.S. citizen who has been given permission to make his or her permanent home in the United States. If you acquire permanent residence, you will be issued a green card to prove it. The terms permanent resident and 'green card holder' mean exactly the same thing. You cannot be a permanent resident without a green card and you cannot have a green card without being a permanent resident. As a permanent resident, you may travel as much as you like, but your place of residence must be the United States and you must keep that residence on a permanent basis. If you leave the United States and stay away for more than a year, you risk losing your green card.

A person or entity (such as a corporation) that must be included in a lawsuit in order for the court to render a final judgment that will be just to everyone concerned. For example, if a person sues his neighbors to force them to prune a tree that poses a danger to his house, he must name all owners of the neighboring property in the suit.

The act of changing a written contract when one of the parties can prove that the actual agreement was different than what's written down. The changes are usually made by a court when both parties overlooked a mistake in the document, or when one party has deceived the other.

The power of the federal or state government to take private property for a public purpose, even if the property owner objects. The Fifth Amendment to the United States Constitution allows the government to take private property if the taking is for a public use and the owner is 'justly compensated' (usually, paid fair market value) for his or her loss. A public use is virtually anything that is sanctioned by a federal or state legislative body, but such uses may include roads, parks, reservoirs, schools, hospitals or other public buildings. Sometimes called condemnation, taking or expropriation.
