Signing a contract in the Netherlands: ten tips on Dutch contract law

Signing a contract in the Netherlands means signing under Dutch law, and Dutch law reaches further than the words on the page. An agreement comes about through offer and acceptance (Article 6:217 of the Dutch Civil Code, Burgerlijk Wetboek), it is in principle form-free, and what the parties may reasonably expect of each other can add duties that were never written down. That is the single most important thing to understand before you sign.
This article sets out what Dutch contract law requires for a binding agreement, the terms you will meet in a Dutch contract, and ten practical checks to run before you commit. It is written for businesses and individuals doing deals with Dutch counterparties, whether the contract is drafted in Dutch or in English.

What makes a contract binding under Dutch law

A contract requires an offer and its acceptance, and behind that a real meeting of minds (wilsovereenstemming). Dutch law works with the interplay of intention and reliance laid down in Articles 3:33 and 3:35 BW: what counts is what you declared and what the other party could reasonably understand from it. Someone who signs a document they did not read is usually bound by it, because the other side was entitled to rely on the signature.
There is no requirement of consideration in Dutch law. A promise does not need to be paid for to be enforceable, which means that a short e-mail confirming terms can bind you just as firmly as a twenty-page agreement. Most contracts are also form-free: unless the law says otherwise, an oral agreement is valid. Proving it is the problem, not its validity.
Freedom of contract (contractsvrijheid) is the starting point, but it stops where mandatory law begins. Consumer protection, employment law, residential tenancy and commercial agency all contain rules the parties cannot set aside to the detriment of the protected party. A clause that conflicts with such a rule is not clever drafting; it is a clause that will not hold.
Running through all of it is reasonableness and fairness (redelijkheid en billijkheid), in Articles 6:2 and 6:248 BW. It works in two directions. It fills gaps, adding obligations the contract does not mention, such as a duty to warn or to cooperate. And it can set a clause aside, but only where relying on it would be unacceptable by the standards of reasonableness and fairness. That is a high threshold, not a general licence for the court to rebalance a bargain it dislikes.

The Dutch contract terms worth knowing

A handful of Dutch terms recur in almost every agreement, and they do not always map onto their English equivalents.
Algemene voorwaarden are general terms and conditions. Dutch law regulates them separately in Articles 6:231 to 6:247 BW, including a duty to give the other party a genuine opportunity to read them before or at the moment the contract is concluded.
Nakoming is performance, wanprestatie or tekortkoming is a failure to perform, and verzuim is the state of default that usually has to be established first, normally by a written notice of default (ingebrekestelling) under Article 6:82 BW.
Ontbinding is dissolution for breach, opzegging is termination by notice without any breach, and vernietiging is annulment on grounds such as mistake, fraud or abuse of circumstances.
Overmacht is force majeure under Article 6:75 BW: a failure that cannot be attributed to the debtor under the contract, the law or generally accepted views.
Boetebeding is a penalty clause, and exoneratiebeding is a limitation or exclusion of liability.

Ten tips for signing a contract in the Netherlands

Tip 1: read the whole document, including what it refers to

Signatures bind. Dutch courts start from the text and from what the parties could reasonably infer from it, so a clause you skipped is still your clause. Read the annexes, the schedules and anything incorporated by reference, and check whether an entire agreement clause rules out the promises made during the negotiations. Where the contract cites articles of the Civil Code, look them up; the numbers are not decoration.

Tip 2: have the draft reviewed before you sign, not after

A review by a contract lawyer familiar with Dutch law is cheapest at draft stage. Once the contract is signed, the room to manoeuvre narrows to interpretation and to the limited grounds for annulment. A review focuses on the clauses that decide who carries which risk: scope of the obligation, liability, termination, general terms, governing law and forum.

Tip 3: expect reasonableness and fairness to matter

Because Article 6:248 BW can add duties and, in extreme cases, block reliance on a clause, one-sided drafting is less effective in the Netherlands than in some other jurisdictions. A clause that gives one party everything and the other party no remedy at all invites an argument that invoking it is unacceptable. Balanced allocation of risk is not softness; it is what makes a clause enforceable.

Tip 4: check whether the law prescribes a form

Most contracts need no particular form, but the exceptions matter. The purchase of a home by a private buyer must be in writing and gives that buyer a three-day cooling-off period under Article 7:2 BW. A non-competition clause in an employment contract must be agreed in writing with an adult employee (Article 7:653 BW). A guarantee given by a private individual requires a written instrument. Employment contracts themselves do not have to be in writing, but several clauses within them do, which is a common misunderstanding.
For electronic contracting, the eIDAS Regulation (EU) 910/2014 and Article 3:15a BW govern signatures. A qualified electronic signature has the same legal effect as a handwritten one; a simple scanned image does not automatically carry the same weight, and for high-value agreements the difference is worth the extra step.

Tip 5: choose the governing law and the forum deliberately

In cross-border contracts, choice of law is governed by the Rome I Regulation and jurisdiction by the Brussels I bis Regulation. Choose both explicitly and consistently: a Dutch law clause combined with a foreign forum clause, or an arbitration clause that contradicts the court clause elsewhere in the contract, produces exactly the preliminary dispute you were trying to avoid.
Dutch law and the Dutch courts are a workable choice for deals with Dutch counterparties. The Netherlands Commercial Court, a chamber of the Amsterdam court, hears international commercial disputes in English, at higher court fees than the ordinary courts. Arbitration and mediation are alternatives worth weighing on speed, cost and confidentiality. Remember that a choice of law cannot deprive a consumer or an employee of the protection of the mandatory rules that would otherwise apply to them.

Tip 6: hand over your general terms and conditions in time

The rule that catches out most businesses is the duty of disclosure. Under Articles 6:233 and 6:234 BW your general terms can be annulled if the other party was not given a reasonable opportunity to take note of them before or when the contract was concluded. Referring to a set of terms filed with the Chamber of Commerce or available on request is generally not enough where handing them over was feasible: attach them, or in an electronic contract make them available in a form the other party can store.
Where both parties refer to their own terms, Article 6:225 BW gives priority to the set referred to first, unless the second party expressly rejects the first set. Say so explicitly in your acceptance if you want your own conditions to prevail. Consumers get further protection from the lists of terms that are always unreasonable or presumed unreasonable in Articles 6:236 and 6:237 BW. Our page on general terms and conditions sets out how to draft and deploy them.

Tip 7: draft liability and penalty clauses that will survive

Dutch law allows parties to limit or exclude liability, but a court will refuse to give effect to an exclusion where the failure was caused by intent or deliberate recklessness on the part of the debtor or of its senior management. Consumer contracts face additional limits. A cap tied to the contract value, combined with insurance, usually protects better than a sweeping exclusion that a court can set aside in full.
Be precise about what is excluded. Terms such as indirect or consequential loss have no fixed statutory meaning in Dutch law, so define the heads of loss you mean, whether that is lost profit, business interruption, reputational damage or the cost of substitute performance.
Penalty clauses deserve equal care. Under Article 6:92 BW a contractual penalty takes the place of statutory damages unless the contract provides otherwise, so a party that wants the option of claiming actual loss instead of the penalty must say so. The court may reduce a penalty under Article 6:94 BW where fairness manifestly requires it, but it applies that power with restraint.

Tip 8: know how the contract can be brought to an end

Dissolution for breach, ontbinding, is available under Article 6:265 BW for any failure to perform, unless the failure, given its minor significance, does not justify it. It normally requires the debtor to be in default first, which in most cases means a written notice of default setting a reasonable period for performance. Dissolution can be effected by a written declaration under Article 6:267 BW; going to court is not always necessary.
Dissolution does not have retroactive effect. It releases both parties from their future obligations and turns what has already been performed into obligations to undo, so payments made may have to be repaid and goods returned. That is a different outcome from a contract being annulled, which does wipe the agreement out from the start.
Opzegging is the route for continuing contracts without a breach. Where the contract is silent, Dutch case law requires a reasonable notice period, and in some relationships compensation, taking account of the duration of the relationship and the investments made. Do not assume you can walk away from a long-standing distribution or service relationship on a month’s notice because the contract does not mention one.
A force majeure clause is worth drafting rather than leaving to Article 6:75 BW. Name the events, state who bears which cost, set a notification duty and provide for what happens if the situation persists.

Tip 9: complain in writing and complain in time

Article 6:89 BW requires a creditor who discovers a defect in performance to protest within a reasonable time. Miss that window and you can lose the right to complain at all, however serious the defect. In consumer sales of movable goods, notice within two months of discovery is in any event timely under Article 7:23 BW; that two-month rule does not apply to the purchase of a house, where the standard is simply a reasonable time.
Separately, keep an eye on limitation. Most contractual claims are time-barred five years after they become due, and claims for damages five years after the claimant became aware of both the damage and the person liable. A limitation period can be interrupted by a written notice reserving your rights, under Article 3:317 BW. Sending that letter costs nothing; letting the period run out costs the claim.

Tip 10: keep the record of the negotiations and of performance

Dutch courts interpret contracts by looking at the text and at what the parties could reasonably expect of each other in the circumstances, which means pre-contractual correspondence can carry real weight. Keep the drafts, the e-mails and the minutes. During performance, confirm deliveries, approvals, delays and complaints in writing, and record every amendment as a signed variation rather than as an oral understanding.
That record also matters at the start. Under Dutch law negotiations are conducted in good faith, but breaking them off is only wrongful in narrow circumstances: the Supreme Court’s CBB/JPO judgment of 12 August 2005 requires that it be unacceptable to do so in the light of the other party’s justified expectation that a contract would result. Written reservations while talks are ongoing keep that risk low.

Where Dutch contracts go wrong most often

Four mistakes account for most of the disputes we see. The first is general terms and conditions that were never properly handed over, so the whole set can be annulled at the moment it is needed. The second is an English-language contract drafted on assumptions borrowed from another legal system, in which terms such as best efforts, indemnity or consequential loss are used without a Dutch law meaning being agreed. The third is a termination executed without a notice of default, which turns a justified dissolution into a breach by the terminating party. The fourth is silence: a defect noticed early, mentioned by telephone, and never confirmed in writing.
Language is a related trap. A contract in English is perfectly valid under Dutch law, but if Dutch law governs it, Dutch concepts fill the gaps. Where a bilingual version exists, state which version prevails, and make sure the two say the same thing before you do.

What to do before you sign

Work through a short list. Establish who the counterparty legally is and whether the signatory is authorised, which the Chamber of Commerce register will tell you. Confirm which set of general terms applies and that it has actually been provided. Check the governing law and forum clause for internal consistency. Read the liability, penalty and termination clauses together, because they only make sense as a package. Finally, agree in writing how the contract may be amended, and keep everything.
