Contract

A contract is any legally-enforceable promise or set of promises made between parties. In the civil law, contracts are considered to be part of the general law of obligations. This article describes the law relating to contracts in common law jurisdictions.

Express and implied contracts

A contract can be either an express contract or an implied contract. An express contract is one in which the terms are expressed verbally, either orally or in writing. An implied contract is one in which some of the terms are not expressed in words.

Implied in fact or implied in law

An implied contract can either be implied in fact or implied in law. A contract which is implied in fact is one in which the circumstances imply that parties have reached an agreement even though they have not done so expressly. For example, by going to a doctor for a physical, a patient agrees that he will pay a fair price for the service. If he refuses to pay after being examined, he has breached a contract implied in fact.

Quasi-contract

A contract which is implied in law is also called a quasi-contract, because it is not in fact a contract; rather, it is a means for the courts to remedy situations in which one party would be unjustly enriched were he or she not required to compensate the other. For example, an unconscious patient treated by a doctor at the scene of an accident has not agreed (either expressly or by implication) to pay the doctor for emergency services, but the patient would be unjustly enriched by the doctor's services were the patient not required to compensate the doctor.
