Contrat en droit suisseUn 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.
Social contractIn moral and political philosophy, the social contract is a theory or model that originated during the Age of Enlightenment and usually, although not always, concerns the legitimacy of the authority of the state over the individual. Social contract arguments typically are that individuals have consented, either explicitly or tacitly, to surrender some of their freedoms and submit to the authority (of the ruler, or to the decision of a majority) in exchange for protection of their remaining rights or maintenance of the social order.
Offer and acceptanceOffer and acceptance are generally recognised as essential requirements for the formation of a contract, and analysis of their operation is a traditional approach in contract law. The offer and acceptance formula, developed in the 19th century, identifies a moment of formation when the parties are . This classical approach to contract formation has been modified by developments in the law of estoppel, misleading conduct, misrepresentation, unjust enrichment, and power of acceptance.
Liberté contractuelleLa liberté contractuelle est un principe juridique contenu dans la législation de nombreux pays. Cette notion naît de la théorie de l'autonomie de la volonté. De ce principe découle l'idée selon laquelle les parties sont libres de contracter ou de ne pas contracter avec la personne de leur choix. En common law, le principe de la liberté contractuelle occupe une place très importante d'un point de vue historique, ce qui se reflète amplement en droit américain.
Intention to create legal relationsIntention to create legal relations, otherwise an "intention to be legally bound", is a doctrine used in contract law, particularly English contract law and related common law jurisdictions. The doctrine establishes whether a court should presume that parties to an agreement wish it to be enforceable at law, and it states that an agreement is legally enforceable only if the parties are deemed to have intended it to be a binding contract. A contract is a legally binding agreement.
