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.

An unforeseen and uncontrollable event that excuses a party to a contract from performing his or her duties under that contract. For example, a landlord can break a lease if the property she agreed to rent accidentally burns down before the tenants move in.

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.

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.

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.

A fee charged by real estate brokers and apartment-finding services in exchange for locating a rental property. These fees are permitted by law. Some landlords, however, charge finder's fees merely for renting a place. This type of charge is not legitimate and, in some areas, is specifically declared illegal.

The substitution of a new contract for an old one. A novation may change one of the parties to the contract or the duties that must be performed by the original parties.

At trial, the initial questioning of a party or witness by the side that called him or her to testify. The major purpose of direct examination is to explain your version of events to the judge or jury and to undercut your adversary's version. Good direct examination seeks to prove all facts necessary to satisfy the plaintiff's legal claims or causes of action -- for example, that the defendant breached a valid contract and, as a result, the plaintiff suffered a loss.

A form filed with the county recorder's office to put on record your right to a homestead exemption. In most states, the homestead exemption is automatic--that is, you are not required to record a homestead declaration in order to claim the homestead exemption. A few states do require such a recording, however.
