In a contract, a promise by one party not to hold the other party responsible if the other party carries out the contract in a way that causes damage to the first party. For example, many leases include a hold harmless clause in which the tenant agrees not to sue the landlord if the tenant is injured due to the landlord's failure to maintain the premises. In most states, these clauses are illegal in residential tenancies, but may be upheld in commercial settings.

A rental agreement or lease between a tenant and a new tenant (called a sublessee) who will either share the rental or take over from the first tenant. The sublessee pays rent directly to the tenant. The tenant is still completely responsible to the landlord for the rent and for any damage, including that caused by the sublessee. Most landlords prohibit subleases unless they have given prior written consent. Compare assignment.

A restriction on the use of real estate that governs its use, such as a requirement that the property will be used only for residential purposes. Covenants are found in deeds or in documents that bind everyone who owns land in a particular development. See covenants, conditions and restrictions.

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.

An exception to a zoning ordinance, usually granted by a local government. For example, if you own an oddly shaped lot that could not accommodate a home in accordance with your city's setback requirement, you could apply at the appropriate office for a variance allowing you to build closer to a boundary line.

An arrangement designed to encourage low-and moderate-income families to purchase housing, in which the housing is offered at an extremely favorable price with a low down payment. The catch is that when the owner sells, she gets none of the profit if the market value of the unit has gone up. Any profit returns to the organization that built the home, which then resells the unit at an affordable price.

A legal principle or rule created by one or more decisions of a state or federal appellate court. These rules provide a point of reference or authority for judges deciding similar issues in later cases. Lower courts must apply these rules when faced with similar legal issues. For example, if the Montana Supreme Court decides that a certain type of employment contract overly restricts the right of the employee to quit and get another job, all other Montana courts must apply this same rule.

A non-court procedure for resolving disputes using one or more neutral third parties -- called the arbitrator or arbitration panel. Arbitration uses rules of evidence and procedure that are less formal than those followed in trial courts, which usually leads to a faster, less-expensive resolution. There are many types of arbitration in common use: Binding arbitration is similar to a court proceeding in that the arbitrator has the power to impose a decision, although this is sometimes limited by agreement -- for example, in 'hi-lo arbitration' the parties may agree in advance to a maximum and minimum award. In non-binding arbitration, the arbitrator can recommend but not impose a decision. Many contracts -- including those imposed on customers by many financial and healthcare organizations -- require mandatory arbitration in the event of a dispute. This may be reasonable when the arbitrator really is neutral, but is justifiably criticized when the large company that writes the contract is able to influence the choice of the arbitrator.
