The act of changing a written contract when one of the parties can prove that the actual agreement was different than what's written down. The changes are usually made by a court when both parties overlooked a mistake in the document, or when one party has deceived the other.

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.

Latin for 'that you cause to be done.' This is a court document that instructs a sheriff to seize and sell a defendant's property in order to satisfy a monetary judgment against the defendant.

The component parts of a legal claim or cause of action. To win a lawsuit, a plaintiff must prove every element of a legal claim. For example, here are the elements of a breach of contract claim: There was a valid contract. The plaintiff performed as specified by the contract. The defendant failed to perform as specified by the contract. The plaintiff suffered an economic loss as a result of the defendant's breach of contract.

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 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 law adopted by some cities or towns with desirable vistas -- such as those in the mountains or overlooking the ocean -- that protects a property owner from having his or her view obstructed by growing trees. View ordinances don't cover buildings or other structures that may block views.

A contract giving written permission to use an invention, creative work or trademark. A license provides a way to make money from your invention or creative work without having to manufacture and sell copies yourself. By licensing an invention or work to a company, you get money (often in the form of royalties) in return for allowing the company to use, produce and sell copies of your invention or work in the marketplace.

A deed that transfers whatever ownership interest the transferor has in a particular property. The deed does not guarantee anything about what is being transferred, however. For example, a divorcing husband may quitclaim his interest in certain real estate to his ex-wife, officially giving up any legal interest in the property. Compare grant deed.
