Enrichissement sans cause
En droit civil, l'institution de lenrichissement sans cause (aussi appelé enrichissement illégitime, enrichissement injustifié ou action de in rem verso ), consiste à permettre à une personne qui se sera acquittée sans raison d'une obligation, et qui se sera donc appauvrie, de demander à être remboursée par celui qui s'est enrichi à son détriment. Ainsi, nul ne peut s'enrichir aux dépens d'autrui. Enrichissement sans cause en droit français La notion d'enrichissement sans cause a été reconnue par la Cour de cassation en 1892.
Assumpsit
Assumpsit ("he has undertaken", from Latin, assumere), or more fully, action in assumpsit, was a form of action at common law used to enforce what are now called obligations arising in tort and contract; and in some common law jurisdictions, unjust enrichment. The origins of the action can be traced to the 14th century, when litigants seeking justice in the royal courts turned from the writs of covenant and debt to the trespass on the case. In the early days of the English common law, agreements were enforced in local courts.
Contrat en droit suisse
Un contrat en droit suisse est défini par l'article 1, alinéa premier du Code des obligations : « Le contrat est parfait lorsque les parties ont, réciproquement et d'une manière concordante, manifesté leur volonté ». Comme dans de nombreux pays de tradition juridique romano-civiliste, le contrat en droit suisse est l'échange d'au moins deux manifestations de volonté, appelées l'offre et l'acceptation, par lesquelles les parties décident de produire un effet juridique. Le contrat est donc un acte juridique bilatéral ou multilatéral.
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.
English unjust enrichment law
The English law of unjust enrichment is part of the English law of obligations, along with the law of contract, tort, and trusts. The law of unjust enrichment deals with circumstances in which one person is required to make restitution of a benefit acquired at the expense of another in circumstances which are unjust. The modern law of unjust enrichment encompasses what was once known as the law of quasi-contract. Its precise scope remains a matter of controversy.
Money had and received
An 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.
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.
