Quasi-contract
A 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. History In common law jurisdictions, the law of quasi-contract can be traced to the medieval form of action known as ''indebitatus assumpsit''. In essence, the plaintiff would recover a money sum from the defendant ''as if'' the defendant had promised to pay it: that is, ''as if'' there were a contract subsisting between the parties. The defendant's promise—their agreement to be bound by the "contract"—was implied by law. The law of quasi-contract was generally used to enforce restitutionary obligations. The form of a ...

Law Of Obligations
The law of obligations is one branch of private law under the civil law legal system and so-called "mixed" legal systems. It is the body of rules that organizes and regulates the rights and duties arising between individuals. The specific rights and duties are referred to as ''obligations'', and this area of law deals with their creation, effects and extinction. An obligation is a legal bond (''vinculum iuris'') by which one or more parties (obligants) are bound to act or refrain from acting. An obligation thus imposes on the ''obligor'' a duty to perform, and simultaneously creates a corresponding right to demand performance by the ''obligee'' to whom performance is to be tendered. History The word originally derives from the Latin "obligare" which comes from the root "lig" which suggests being bound, as one is to God for instance in "re-ligio". This term first appears in Plautus' play Truculentus at line 214. Obligations did not originally form part of Roman Law, which mostly c ...

Unjust Enrichment
In laws of equity, unjust enrichment occurs when one person is enriched at the expense of another in circumstances that the law sees as unjust. Where an individual is unjustly enriched, the law imposes an obligation upon the recipient to make restitution, subject to defences such as change of position. Liability for an unjust (or unjustified) enrichment arises irrespective of wrongdoing on the part of the recipient. The concept of unjust enrichment can be traced to Roman law and the maxim that "no one should be benefited at another's expense": ''nemo locupletari potest aliena iactura'' or ''nemo locupletari debet cum aliena iactura''. The law of unjust enrichment is closely related to, but not co-extensive with, the law of restitution. The law of restitution is the law of gain-based recovery. It is wider than the law of unjust enrichment. Restitution for unjust enrichment is a subset of the law of restitution in the same way that compensation for breach of contract is a subset of ...

Contract Law
A contract is a legally enforceable agreement between two or more parties that creates, defines, and governs mutual rights and obligations between them. 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. Contract law, the field of the law of obligations concerned with contracts, is based on the principle that agreements must be honoured. Contract law, like other areas of private law, varies between jurisdictions. The various systems of contract law can broadly be split between common law jurisdictions, civil law jurisdictions, and mixed law jurisdictions which combine elements of both common and civil law. Common law jurisdictions typically require contracts to include consideration in order to be valid, whereas civil and most mixed law jurisdictions solely require a meeting of the min ...

Officious Intermeddler
An officious intermeddler is a person who voluntarily, and without request or pre-existing legal duty, interjects him- or herself into the affairs of another, and then seeks remuneration for services or reimbursement. Example: Person "A" leaves for vacation for two weeks during the summer. Person "B" mows "A"s lawn. "B" requests payment for this service. Under common law doctrine, "B" is not entitled to any payment from "A" beyond whatever "A" cares to give. If B tries to coerce payment, B is an officious intermeddler. Emergencies An exception to this rule, however, is if a doctor gives medical treatment to an unconscious victim. Although the unconscious person did not ''request'' the doctor's services, a court may deem it reasonable for the doctor to presume that such services would be desired by the person, had they been conscious. Quasi-contracts Another exception to this rule, in certain jurisdictions, is the existence of a quasi-contract. In general, in order for a contract t ...

Form Of Action
The 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. In the early Middle Ages, the focus was on the procedure that was employed to bring one's claim to the royal courts of King's Bench or Common Pleas: it was the ''form'' of one's action, not its substance, which occupied legal discussion. This restrictive approach is one of the reasons which attracted litigants to petition the King directly, which eventually led to the development of a separate court known as the Court of Chanc ...

Negotiorum Gestio
''Negotiorum gestio'' (, Latin for "management of business") is a form of spontaneous voluntary agency in which an intervenor or intermeddler, the ''gestor'', acts on behalf and for the benefit of a principal (''dominus negotii''), but without the latter's prior consent. The gestor is only entitled to reimbursement for expenses and not to remuneration, the underlying principle being that ''negotiorum gestio'' is intended as an act of generosity and friendship and not to allow the gestor to profit from his intermeddling. This form of intervention is classified as a quasi-contract and found in civil-law jurisdictions and in mixed systems (e.g. Louisiana, Scots, South African, and Philippine laws). For example, while you are traveling abroad, a typhoon hits your home town and the roofing of your house is in danger. To avoid the catastrophic situation, your neighbour does something urgently necessary. You are the 'principal' and your neighbour here is the 'gestor', the act of which ...

Legal Fiction
A legal fiction is a fact assumed or created by courts, which is then used in order to help reach a decision or to apply a legal rule. The concept is used almost exclusively in common law jurisdictions, particularly in England and Wales. Development of the concept A legal fiction typically allows the court to ignore a fact that would prevent it from exercising its jurisdiction by simply assuming that the fact is different. In cases where the court must determine whether a standard has been reached, such as whether a defendant has been negligent, the court frequently uses the legal fiction of the "reasonable man". This is known as the "objective test", and is far more common than the "subjective test" where the court seeks the viewpoint of the parties (or "subjects"). Sometimes, the court may apply a "mixed test", as in the House of Lords' decision in ''DPP v Camplin'' 1978. Legal fictions are different from legal presumptions which assume a certain state of facts until th ...

Restitution In English Law
The English law of Restitution is the law of gain-based recovery. Its precise scope and underlying principles remain a matter of significant academic and judicial controversy. Broadly speaking, the law of restitution concerns actions in which one person claims an entitlement in respect of a ''gain'' acquired by another, rather than compensation for a ''loss''. Framework Many academic commentators have sought to impose structure upon the law of restitution by searching for a common rationale and constructing taxonomies of the various types of claim. Whether such frameworks can account for the diverse range of restitutionary claims remains a controversial question. The implications of such frameworks for the relationship between law and Equity has often been a significant flashpoint in academic and judicial debate. As the law currently stands, the law of restitution can be usefully divided into (at least) three broad categories: * Restitution for unjust enrichment * Restitution for ...

Goff & Jones
''Goff and Jones on the Law of Unjust Enrichment'' (formerly ''Goff and Jones on the Law of Restitution'', usually simply abbreviated to ''Goff & Jones'') is the leading authoritative English law textbook on restitution and unjust enrichment. First written by Robert Goff and Gareth Jones, it is presently in its tenth edition. It is published by Sweet & Maxwell and forms part of the Common Law Library. As a textbook it is somewhat remarkable in that although the first edition was published in 1966, it was not until 1991 (25 years later) that the House of Lords formally recognised unjust enrichment as a separate branch of jurisprudence. It is notable that a number of the key decisions in the field have been handed down by Lord Goff, and often reflect the analysis which has previously expressed academically in ''Goff & Jones''. For example, Goff's judgment in '' Barclays Bank Ltd v W J Simms, Son and Cooke (Southern) Ltd'' 9801 QB 677 was described as "the ''Donoghue v Steven ...

Quantum Meruit
''Quantum 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. Situations ''Quantum meruit'' is the measure of damages where an express contract is mutually modified by the implied agreement of the parties, or not completed. While there is often confusion between the concept of ''quantum meruit'' and that of "unjust enrichment" of one party at the expense of another, the two concepts are distinct. The concept of ''quantum meruit'' applies in (but is not limited to) the following set of situations: #When a pers ...
