French contract law

Contracts in systems based on the Napoleonic code can typically be categorised as consensual contracts, which are formed solely on the basis of the parties' exchange of consent to form legal relations; real contracts, which are concluded not by an explicit exchange of mutual assent but by the handing over of a chose; or contrats solennels, which are analogous to deeds in common law jurisdictions and require notarial formalities to be concluded. Thus, while consensual contracts and real contracts can be formed solely by the actions of the parties, contrats solennels can only be formed via specified formal processes. Nevertheless, all three categories of contracts are based solely on the exchange of mutual assent, differing only in the manner in which assent is expressed.
