What are the requirements for contract formation under Dutch law?

Dutch term: Totstandkoming overeenkomst | Legal basis: Articles 6:217-6:225 BW

Under Dutch law, a contract is formed by an offer and a matching acceptance (article 6:217 BW). The offer must be sufficiently specific regarding the main elements of the contract. Acceptance must correspond with the offer; any modification constitutes a counter-offer rather than valid acceptance (article 6:225 BW). Written form is not generally required for the validity of commercial contracts, although specific formalities apply to certain categories (real estate, consumer credit, arbitration clauses, franchise pre-contractual disclosure).

Dutch law recognises the principle of consensualism: mere agreement creates binding obligations. Written documentation serves evidentiary purposes but is not constitutive of the contract. Silence generally does not constitute acceptance, but it can in specific circumstances where the parties have an ongoing relationship or where trade usage creates an expectation of response. Electronic contracts (including click-wrap and browse-wrap agreements) are generally valid under Dutch law, subject to specific consumer protection rules for distance contracts.

Why it matters for international businesses

For international businesses, the key practical difference from some other jurisdictions is that verbal agreements are legally binding under Dutch law. A handshake deal, a phone call or an email exchange can create a binding contract if the essential terms are agreed. Documenting agreements in writing is strongly advisable for evidentiary purposes, but the absence of a signed document does not mean there is no contract.
