A lump sum cash payment paid by a buyer when he or she purchases a major piece of property, such as a car or house. The buyer typically takes out a loan for the balance remaining, and pays it off in monthly installments over time.

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 legal doctrine stating that if a person receives money or other property through no effort of his own, at the expense of another, the recipient should return the property to the rightful owner, even if the property was not obtained illegally. Most courts will order that the property be returned if the party who has suffered the loss brings a lawsuit.

A rental agreement that provides for a one-month tenancy that is automatically renewed each month unless either tenant or landlord gives the other the proper amount of written notice (usually 30 days) to terminate the agreement. Some landlords prefer to use month-to-month tenancies because it gives them the right to raise the rent after giving proper notice. This type of rental also provides a landlord with an easy way to get rid of troublesome tenants, because in most states month-to-month tenancies can be terminated for any reason.

A determination of the value of something, such as a house, jewelry or stock. A professional appraiser -- a qualified, disinterested expert -- makes an estimate by examining the property, and looking at the initial purchase price and comparing it with recent sales of similar property. Courts commonly order appraisals in probate, condemnation, bankruptcy or foreclosure proceedings in order to determine the fair market value of property. Banks and real estate companies use appraisals to ascertain the worth of real estate for lending purposes. And insurance companies require appraisals to determine the amount of damage done to covered property before settling insurance claims.

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.

Land and the property permanently attached to it, such as buildings, houses, stationary mobile homes, fences and trees. In legalese, real estate is also called real property.

Two or more tenants who rent the same property under the same lease or rental agreement. Each co-tenant is 100% responsible for carrying out the rental agreement, which includes paying the entire rent if the other tenant skips town and paying for damage caused by the other tenant.
