A promise that pledges nothing, because it is vague or because the promisor can choose whether or not to honor it. Such promises are not legally binding.

Federal laws that prohibit housing discrimination on the basis of race or color, national origin, religion, sex, familial status or disability.

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 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 statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.

Removal of a tenant from rental property by a law enforcement officer. First, the landlord must file and win an eviction lawsuit, also known as an 'unlawful detainer.'

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 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. For example, a contingency in a contract for the purchase of a house might state that if the buyer does not approve the inspection report of the physical condition of the property, the buyer does not have to complete the purchase.
