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 service contract that covers a major housing system--for example, plumbing or electrical wiring--for a set period of time from the date a house is sold. The warranty guarantees repairs to the covered system and is renewable.

A sale of a house in which the proceeds fall short of what the owner still owes on the mortgage. Many lenders will agree to accept the proceeds of a short sale and forgive the rest of what is owed on the mortgage when the owner cannot make the mortgage payments. By accepting a short sale, the lender can avoid a lengthy and costly foreclosure, and the owner is able to pay off the loan for less than what he owes. See also deed in lieu (or foreclosure).

(1) An informal written document. A memorandum may be used in any number of circumstances, but most lawyers are best acquainted with the interoffice memorandum--a document prepared by a junior associate in a law office or a judge's law clerk outlining the facts, procedural elements and legal arguments involved in a particular legal matter. These memos are reviewed by senior lawyers and judges who use them to decide how to proceed with the case. (2) Any written record, including a letter or note, that proves that a contract exists between two parties. This type of memo may be enough to validate an oral (spoken) contract that would otherwise be unenforceable because of the statute of frauds. (Under the statute of frauds, an oral contract is invalid if it can't be completed within one year from the date the contract is made.)

The right of a property owner or tenant to enjoy his or her property without interference. Disruption of quiet enjoyment may constitute a nuisance. Leases and rental agreements often contain a 'covenant of quiet enjoyment,' expressly obligating the landlord to see that tenants have the opportunity to live undisturbed.

The many types of information presented to a judge or jury designed to convince them of the truth or falsity of key facts. Evidence typically includes testimony of witnesses, documents, photographs, items of damaged property, government records, videos and laboratory reports. Rules that are as strict as they are quirky and technical govern what types of evidence can be properly admitted as part of a trial. For example, the hearsay rule purports to prevent secondhand testimony of the 'he said, she said' variety, but the existence of dozens of exceptions often means that hairsplitting lawyers can find a way to introduce such testimony into evidence. See also admissible evidence, inadmissible evidence.

Principles of international law so fundamental that no nation may ignore them or attempt to contract out of them through treaties. For example, genocide and participating in a slave trade are thought to be jus cogens.
