ContractA contract is an agreement that specifies certain legally enforceable rights and obligations pertaining to two or more mutually agreeing parties. A contract typically involves the transfer of goods, services, money, or a promise to transfer any of those at a future date. In the event of a breach of contract, the injured party may seek judicial remedies such as damages or rescission. A binding agreement between actors in international law is known as a treaty.
Form of actionThe forms of action were the different procedures by which a legal claim could be made during much of the history of the English common law. Depending on the court, a plaintiff would purchase a writ in Chancery (or file a bill) which would set in motion a series of events eventually leading to a trial in one of the medieval common law courts. Each writ entailed a different set of procedures and remedies which together amounted to the "form of action". The forms of action were abolished during the 19th century, but they have left an indelible mark on the law.
Consideration in English lawConsideration is an English common law concept within the law of contract, and is a necessity for simple contracts (but not for special contracts by deed). The concept of consideration has been adopted by other common law jurisdictions, including the US. Consideration can be anything of value (such as any goods, money, services, or promises of any of these), which each party gives as a quid pro quo to support their side of the bargain. Mutual promises constitute consideration for each other.
English contract lawEnglish contract law is the body of law that regulates legally binding agreements in England and Wales. With its roots in the lex mercatoria and the activism of the judiciary during the industrial revolution, it shares a heritage with countries across the Commonwealth (such as Australia, Canada, India), from membership in the European Union, continuing membership in Unidroit, and to a lesser extent the United States. Any agreement that is enforceable in court is a contract.
Money had and receivedAn action for money had and received to the plaintiff's use is the name for a common law claim derived from the form of action known as indebitatus assumpsit. The action enabled one person to recover money which has been received by another: for example, where a plaintiff paid money to the defendant while labouring under a mistake of fact or where there was a total failure of consideration. The action was a personal action only available in respect of money, rather than other benefits.
Quasi-contractA quasi-contract (or implied-in-law contract or constructive contract) is a fictional contract recognised by a court. The notion of a quasi-contract can be traced to Roman law and is still a concept used in some modern legal systems. Quasi contract laws have been deduced from the Latin statement "Nemo debet locupletari ex aliena jactura", which proclaims that no man should grow rich out of another person's loss. It was one of the central doctrines of Roman law.
Quantum meruitQuantum meruit is a Latin phrase meaning "what one has earned". In the context of contract law, it means something along the lines of "reasonable value of services". In the United States, the elements of quantum meruit are determined by state common law. For example, to state a claim for unjust enrichment in New York, a plaintiff must allege that (1) defendant was enriched; (2) the enrichment was at plaintiff's expense; and (3) the circumstances were such that equity and good conscience require defendants to make restitution.
Restitution and unjust enrichmentRestitution and unjust enrichment is the field of law relating to gains-based recovery. In contrast with damages (the law of compensation), restitution is a claim or remedy requiring a defendant to give up benefits wrongfully obtained. Liability for restitution is primarily governed by the "principle of unjust enrichment": A person who has been unjustly enriched at the expense of another is required to make restitution.
Cause of actionA cause of action or right of action, in law, is a set of facts sufficient to justify suing to obtain money or property, or to justify the enforcement of a legal right against another party. The term also refers to the legal theory upon which a plaintiff brings suit (such as breach of contract, battery, or false imprisonment). The legal document which carries a claim is often called a 'statement of claim' in English law, or a 'complaint' in U.S. federal practice and in many U.S. states.
ConsiderationConsideration is a concept of English common law and is a necessity for simple contracts but not for special contracts (contracts by deed). The concept has been adopted by other common law jurisdictions. The court in Currie v Misa declared consideration to be a “Right, Interest, Profit, Benefit, or Forbearance, Detriment, Loss, Responsibility”. Thus, consideration is a promise of something of value given by a promissor in exchange for something of value given by a promisee; and typically the thing of value is goods, money, or an act.
