A doctrine that prevents a defendant from re-litigating an issue after it has been lost.

A provision in a contract stating that some or all of the terms of the contract will be altered or voided by the occurrence of a specific event.

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 payment required by a landlord to ensure that a tenant pays rent on time and keeps the rental unit in good condition. If the tenant damages the property or leaves owing rent, the landlord can use the security deposit to cover what the tenant owes.

The legally prescribed time limit in which a lawsuit must be filed. Statutes of limitation differ depending on the type of legal claim, and often the state. For example, many states require that a personal injury lawsuit be filed within one year from the date of injury -- or in some instances, from the date when it should reasonably have been discovered -- but some allow two years. Similarly, claims based on a written contract must be filed in court within four years from the date the contract was broken in some states and five years in others. Statute of limitations rules apply to cases filed in all courts, including federal court.
