Article 1113 of the Civil Code lays the foundation for contract formation in French law. Arising from the reform of the law of obligations that came into effect on October 1, 2016, it formalizes a principle that jurisprudence had long applied: the contract is formed by the meeting of wills. Two paragraphs are sufficient to structure the entire contractual process, from offer to acceptance.
Offer and acceptance: the mechanism of the meeting of wills
Article 1113 of the Civil Code states that a contract is formed by the meeting of an offer and an acceptance through which the parties express their intention to be bound. This formulation, seemingly clear, structures the entire law of contractual formation.

The offer must be sufficiently precise and firm so that a simple acceptance is enough to form the contract. It contains the elements of the contemplated contract and expresses the author’s intention to be bound in case of acceptance. The acceptance, for its part, must be straightforward: any modification of the terms of the offer constitutes a counter-offer, not an acceptance.
A ruling from the commercial chamber of the Court of Cassation on February 8, 2023 (n° 21-13.536) illustrates the rigor of this mechanism. The Court held that the acceptance of a stipulation regarding the place of delivery could not be characterized when the signed document did not refer to this clause.

Neither the execution of the contract nor the issuance of an invoice could constitute an acceptance of the offer. The proof of the meeting of wills adheres to precise formal requirements, even in established commercial relationships.
To delve deeper into the text itself and its connection with the following articles, an article offers details on Article 1113 of the Civil Code from an educational perspective.
Article 1113 and digital contracts: when the interface determines consent
The transposition of Article 1113 to contracts concluded online has become one of the most active contentious areas in recent years. On a platform, a marketplace, or a mobile application, the question takes a very concrete form: at what exact moment did the user accept the offer?
Several decisions from courts of appeal and judicial tribunals, rendered between 2022 and 2024, analyze the design of the user interface to determine whether a valid acceptance has occurred. The position of a “Confirm” button, the use of double-clicking, the readability of the general terms and conditions, or the pre-checking of a box become elements of legal qualification.
In certain cases, judges have held the absence of a meeting of wills when the purchasing process was misleading or ambiguous. A poorly placed button, general terms and conditions accessible only via a discreet link at the bottom of the page, or a pre-checking mechanism may be sufficient to challenge the formation of the contract.
UX design and contractual validity
Recent doctrinal comments, particularly in the JurisClasseur (a section dedicated to Articles 1113 to 1122), highlight this convergence between classical contract theory and interface design. The law of obligations now incorporates a technical dimension that did not exist at the time of drafting the Civil Code.
This evolution raises questions that remain open. The criteria used by judges to assess the clarity of an interface vary from one jurisdiction to another. Field feedback diverges on this point: some e-commerce actors believe that double-clicking sufficiently secures consent, while recent decisions suggest that this mechanism is not always adequate.
Proof of acceptance in a dematerialized environment
Beyond the qualification of acceptance, a second contentious front concerns the proof of this acceptance in computer systems. The litigation is no longer limited to whether the contract is formed, but to establishing that the opposing party has indeed expressed their intention.
The elements of proof mobilized in recent disputes are technical in nature:
- The timestamp of the click or electronic signature, which allows for precise identification of the moment of acceptance
- Server logs, which record the user’s journey and can demonstrate that they accessed the contractual conditions before confirming
- The proof of the effective delivery of the general terms and conditions, distinct from their mere posting on the site
The burden of proof lies with the party invoking the existence of the contract. In practice, this means that the professional operating a platform must be able to produce reliable technical traces. A poorly designed logging system can compromise the proof of the contract, even if acceptance has actually taken place.
Connection with the eIDAS regulation and electronic signature
The qualified electronic signature provides a higher level of proof, but the majority of online contracts are formed by simple clicking, without resorting to this mechanism. The available data does not allow for a conclusion that French jurisdictions systematically require a high level of electronic signature to validate the formation of a B2C online contract.
On the other hand, for high-value contracts or those containing sensitive clauses (jurisdiction clause, liability limitation clause), judges tend to examine the quality of the acceptance process more closely.
Scope of Article 1113 in current contractual litigation
Article 1113 is not limited to a theoretical statement. It directly underpins the grounds for cassation invoked in disputes concerning contract formation. Lawyers use it as leverage to contest the very existence of an agreement, prior to any discussion on execution or resolution.
Three frequently recurring contentious situations are:
- Disagreement over the accepted terms, when the offer included several contractual documents and the co-contractor only signed part of them
- Retraction of the offer before acceptance, governed by Articles 1115 and following, but whose foundation rests on the mechanics established by Article 1113
- The dispute over the formation of the contract on a digital platform, a rapidly expanding area
The ruling of the Court of Cassation on February 8, 2023 marks the first direct application of Article 1113 in its wording resulting from the reform. This decision confirms that the jurisdictions apply the text with the same evidentiary requirements as the old law, while paving the way for an interpretation adapted to new modes of contracting.
The framework established by Article 1113 of the Civil Code remains stable in its principles, but its concrete application evolves in line with commercial practices. The question of proof of digital consent is now the focus of attention for practitioners and jurisdictions, without a uniform standard having yet emerged.
