An extraordinary and unexpected natural event, such as a hurricane, tornado, earthquake or even the sudden death of a person. An act of God may be a defense against liability for injuries or damages. Under the law of contracts, an act of God often serves as a valid excuse if one of the parties to the contract is unable to fulfill his or her duties -- for instance, completing a construction project on time.

A provision in a contract that preserves the rest of the contract if a portion of it is invalidated by a court. Without a severability clause, a decision by the court finding one part of the contract unenforceable would invalidate the entire document.

A nonrefundable fee charged by a landlord when a tenant moves in. The fee covers the cost of cleaning the rented premises after you move out, even if you leave the place spotless. Cleaning fees are illegal in some states and specifically allowed in others, but most state laws are silent on the issue. Landlords in every state are allowed to use the security deposit to clean a unit that is truly dirty.

A legally binding contract in which a person or business promises to treat specific information as a trade secret and not disclose it to others without proper authorization. Nondisclosure agreements are often used when a business discloses a trade secret to another person or business for such purposes as development, marketing, evaluation or securing financial backing. Although nondisclosure agreements are usually in the form of written contracts, they may also be implied if the context of a business relationship suggests that the parties intended to make an agreement. For example, a business that conducts patent searches for inventors is expected to keep information about the invention secret, even if no written agreement is signed, because the nature of the business is to deal in confidential information.

A seller's taking advantage of a buyer due to their unequal bargaining positions, perhaps because of the buyer's recent trauma, physical infirmity, ignorance, inability to read or inability to understand the language. The unfairness must be so severe that it is shocking to the average person. It usually includes the absence of any meaningful choice on the part of the buyer and contract terms so one-sided that they unreasonably favor the seller. A contract will be terminated if the buyer can prove unconscionability.

The taking of physical evidence or property by law enforcement officials. This runs the gamut from taking blood for a drug test to impounding a car used in a robbery. The police must generally obtain a search warrant, or court order, before they can seize personal property.

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.

Principles of international law so fundamental that no nation may ignore them or attempt to contract out of them through treaties. For example, genocide and participating in a slave trade are thought to be jus cogens.
