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. For example, if you get a new job and promise to work for three years, unless you resign sooner, you haven't made a valid contract and can resign or be fired at any time.

A person who specializes in matching home buyers with appropriate mortgage lenders. For a fee--often paid by the lender--a loan broker provides any easy and effective way to find the cheapest mortgage rates.

A proposal to enter into an agreement with another person. An offer must express the intent of the person making the offer to form a contract, must contain some essential terms--including the price and subject matter of the contract--and must be communicated by the person making the offer. A legally valid acceptance of the offer will create a binding contract.

A phrase used in property law to describe a right or duty that remains with a piece of property no matter who owns it. For example, the duty to allow a public beach access path across waterfront property would most likely pass from one owner of the property to the next.

An agreement, generally included in an employment contract or a contract for the sale of a business, where one party agrees not to compete with the other party for a specific period of time and within a particular area. Salespeople, for example, often sign noncompetition agreements that prevent them from using the contacts gained by one employer to benefit another employer. Or a salesperson may sign what is known as a 'noncompete,' agreeing not to sell within a particular area, or even work in the same type of business. In some states, such as California, courts view noncompetition agreements with disfavor and will not enforce them unless the restrictions are very narrow. In other states, courts routinely uphold them.

A provision in a lease that absolves the landlord from responsibility for all damages, injuries or losses occurring on the property, including those caused by the landlord's actions. Most states have laws that void exculpatory clauses in rental agreements, which means that a court will not enforce them.

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.
