Ontbinding van overeenkomst is the Dutch legal term for dissolving a contract because the other party has failed to perform. Article 6:265 of the Dutch Civil Code (Burgerlijk Wetboek, BW) gives every contracting party that right in the event of any failure in performance, unless the failure is so minor or so unusual in nature that it does not justify dissolution. Dissolution operates forward in time: it releases both sides from what is still to come and converts what has already been performed into an obligation to undo.
What ontbinding van overeenkomst means under Dutch law
Dissolution is one of the remedies Dutch contract law offers a creditor whose counterparty does not deliver, does not pay, or delivers something that does not answer to the agreement. That failure is a tekortkoming in de nakoming, in practice usually called wanprestatie. The creditor may choose: demand performance, suspend its own obligations, claim damages, or dissolve. Dissolution is the heaviest of these, because it ends the commercial relationship, and it is the only one that requires you to hand back what you have already received.
It helps to keep three ways of ending a contract apart, because they have entirely different consequences. Dissolution (ontbinding) responds to a failure that occurs while a valid contract is running. Annulment (vernietiging) responds to a defect at the moment the contract was concluded, such as fraud, duress or a fundamental mistake, and wipes the contract out retroactively. Termination by notice (opzegging) simply brings a continuing contract to an end for the future and does not require any failure at all. Choosing the wrong instrument is one of the most common reasons a claim fails, so it pays to be clear about which one your situation actually calls for. Our overview of the elements of a valid contract explains when an agreement is validly formed in the first place.
Dissolution under article 6:269 BW has no retroactive effect. The contract is not treated as if it never existed; it is unwound from the moment of dissolution, and the parties owe each other restitution for what has already changed hands.
That absence of retroactive effect has practical consequences that are easy to overlook. Clauses that are meant to survive the end of the agreement, such as a confidentiality obligation, a choice of law, an arbitration clause or a penalty clause, remain in force after dissolution. So does a contractual limitation of liability, unless invoking it would be unacceptable in the circumstances. Dissolving a contract therefore does not free you from every obligation you signed up to; it frees you from the obligations that were still to be performed.
When a breach justifies dissolution
The threshold in article 6:265 lid 1 BW is lower than most people assume. The main rule is that every failure in performance entitles the other party to dissolve. The exception, the so-called tenzij-formula, is that dissolution is not available where the failure, given its special nature or minor significance, does not justify dissolution with all its consequences. The Supreme Court confirmed in 2018 that rule and exception must be read together as a single test: the question is whether the breach, weighed against the far-reaching effects of dissolution, is serious enough to warrant it. There is no separate hurdle beyond that weighing.
Two points follow from the way the provision is drafted. First, the burden of proof lies with the party resisting dissolution: it is the defaulting party who must argue and prove that the failure is too trivial to carry this remedy. Second, the assessment is made on all the circumstances of the case, including the nature of the contract, the size of the failure in relation to the whole performance, whether the failure can still be repaired, how much the creditor stands to lose, and how the defaulting party behaved once the problem surfaced.
In commercial practice the failures that clear the threshold usually look like this:
- a supplier delivers machinery that does not meet the agreed specification and cannot be brought up to specification within a workable period;
- a buyer leaves a substantial part of the price unpaid after repeated demands;
- a contractor abandons the works, or performs so defectively that completing the job means starting again;
- a service provider delivers a report or a piece of software that is unusable for the purpose both parties had in mind.
Failures that will normally not carry dissolution include a delay of a few days where time was not of the essence, a cosmetic defect in an otherwise sound delivery, or a shortfall in a marginal part of a large contract. In those cases the proportionate remedies are a price reduction, damages, or suspension of your own performance until the problem is fixed. For the underlying concept, see our glossary entry on breach of contract.
What the contract itself says about dissolution
Before you rely on the statutory rules, read the agreement and the general terms and conditions that apply to it. Commercial parties frequently exclude or restrict the right to dissolve, make it conditional on a fixed cure period, or reserve dissolution for an exhaustive list of events. Those clauses are in principle valid between businesses, and a dissolution declared in breach of them will not stand. In consumer contracts the room is much narrower: a clause that deprives a consumer of the right to dissolve is on the statutory black or grey list of unfair terms in articles 6:236 and 6:237 BW and can be annulled. If your standard documents are older than a few years, it is worth checking them against our guide to general terms and conditions.
Putting the other party in default first
In most cases you cannot dissolve straight away. Article 6:265 lid 2 BW makes the right to dissolve conditional on the debtor being in default (verzuim), unless performance has become permanently or temporarily impossible. Default does not arise by itself when a deadline passes; as a rule it has to be created by a written notice, the ingebrekestelling of article 6:82 BW.
A valid notice of default does two things. It identifies precisely what the other party has failed to do, and it sets a reasonable period within which they must still perform. What counts as reasonable depends on the work involved: a few days for a payment, longer for a repair that requires parts or subcontractors. A period that is plainly too short does not void the notice, but the court will read it as if a reasonable period had been set, and your dissolution will be premature if you act before that period has run. Send the notice in writing, to the contractual address, and keep proof of dispatch. Our practical explanation of the notice of default sets out what such a letter should contain.
The notice of default is not a formality to be rushed. It fixes the moment from which statutory interest runs, it starts the clock on damages caused by delay, and it is the document a court will read first when it assesses whether your dissolution was justified.
When no notice of default is needed
Article 6:83 BW lists the situations in which default arises without any notice at all. There are three, and they are exhaustive:
- a deadline fixed by the contract or by statute passes without performance, and that deadline was meant to operate as a strict cut-off (a fatale termijn);
- the obligation arises from an unlawful act, or consists of paying damages for a failure to perform, and it is not performed immediately;
- the creditor must infer from a statement by the debtor that the debtor will fail to perform.
Alongside these, article 6:265 lid 2 BW itself removes the requirement where performance is permanently or temporarily impossible: if the unique object sold has been destroyed, or the caterer did not appear at the wedding, there is nothing left to demand. Courts are careful here. A date in a contract is not automatically a fatale termijn; it becomes one only if the parties intended missing it to have that effect. When in doubt, send the notice anyway. It costs a day and it removes the most frequently successful defence against dissolution.
Extrajudicial or judicial dissolution
Dutch law offers two routes, and article 6:267 BW makes the first one strikingly simple. Dissolution takes effect through a written declaration by the party entitled to dissolve; no court order is needed. A declaration by electronic means is possible where the other party has made it clear that it is reachable that way. This is buitengerechtelijke ontbinding, extrajudicial dissolution, and it is the normal route in commercial matters.
The declaration should state unambiguously that the contract is dissolved, identify the contract, describe the failure and refer to the notice of default that preceded it, and give the date on which the dissolution takes effect. Do not hedge. A letter that merely announces that you are considering dissolution, or that combines dissolution with a continuing demand for performance, invites the argument that you never actually dissolved anything.
The second route is gerechtelijke ontbinding: you ask the court to dissolve the contract. That is the sensible choice when the facts are contested, when the amounts at stake justify the certainty of a judgment, or when the law requires it. For residential leases it is not a choice at all: article 7:231 BW reserves dissolution of a lease of living space to the court, so a landlord cannot dissolve by letter. Employment contracts are subject to their own regime, discussed below.
Partial dissolution and suspension
Dissolution is not all or nothing. Article 6:270 BW allows partial dissolution, which reduces the mutual obligations proportionally instead of ending the contract entirely. If a supplier delivered four of five machines correctly, you can dissolve for the fifth and keep the rest of the deal alive. Courts tend to look favourably on this, because it is the proportionate response to a partial failure.
There is also a step short of dissolution that is often the better opening move. Under articles 6:262 and 6:263 BW you may suspend your own performance while the other party is not performing, or where you have good reason to fear that it will not perform. Suspension keeps the contract intact, puts commercial pressure on the counterparty, and preserves your position while you send a notice of default. It must be proportionate to the failure, and you should say clearly that you are suspending and why.
What happens after a contract is dissolved
Article 6:271 BW sets out the effect. Dissolution releases both parties from the obligations it covers, and for everything that has already been performed it creates an obligation to undo, the ongedaanmakingsverbintenis. Goods go back, money goes back, and each party may suspend its own restitution until the other performs. Neither side is entitled to keep the benefit of a contract it has just walked away from.
When undoing is impossible
Performances that cannot be returned in kind are settled in money. Article 6:272 BW replaces the obligation to undo with an obligation to pay the value of what was received at the moment of receipt. A painter cannot take the paint off your wall, and a consultant cannot un-give advice, so the question becomes what that performance was worth to you. Where the performance did not meet the agreement, the value is capped by the value of what was actually delivered, not by the price agreed. That is why a badly executed service often results in a very modest value compensation, and sometimes none at all.
Damages on top of dissolution
Dissolution and damages are cumulative, not alternative. Article 6:277 BW entitles the dissolving party to compensation for the loss it suffers because the contract is not performed and is instead unwound. That covers the difference between the agreed price and the cost of a replacement transaction, wasted expenditure, and lost profit that can be substantiated. It does not cover loss you could reasonably have avoided, and it is reduced to the extent that your own conduct contributed to the damage. Keep the evidence: quotations from replacement suppliers, correspondence about the defect, and a clear record of the costs you actually incurred.
Special regimes: consumer sales, leases and employment
The general rules give way to specific ones in several fields, and those specific rules usually restrict rather than expand the right to dissolve.
Consumer sales
In a consumer sale the buyer cannot go straight to dissolution. Article 7:22 BW imposes a hierarchy: the consumer first has a claim to repair or replacement, and only if that is impossible, refused, unreasonably burdensome, or not carried out within a reasonable time and without significant inconvenience does the right arise to dissolve the contract or to reduce the price. Dissolution is also excluded where the non-conformity is too minor to justify it. In addition, article 7:23 lid 1 BW requires the consumer to notify the seller within two months of discovering the defect in a consumer sale of a movable item; that specific two-month rule does not apply to the purchase of a house, where the buyer must complain within a reasonable time judged on the circumstances.
Employment contracts
An employer cannot dissolve an employment contract by letter, and cannot rely on the general contract rules to get around dismissal protection. Dutch dismissal law prescribes the route by the reason for the dismissal. For redundancy on business-economic grounds and for long-term incapacity for work, the employer needs prior permission from the UWV and then gives notice. For all other grounds, including unsatisfactory performance, a damaged working relationship and culpable conduct, the employer asks the subdistrict court (kantonrechter) to dissolve the contract under article 7:671b BW, on one of the grounds listed in article 7:669 lid 3 BW. An employee who wants out can ask the court for dissolution under article 7:671c BW. Both parties can, of course, agree to end the contract by vaststellingsovereenkomst (settlement agreement), which is how the large majority of Dutch employment relationships in fact end.
Where the employer takes the initiative, the employee is in principle entitled to the transitievergoeding (transition payment) under article 7:673 BW. It accrues from the first day of employment, so it is due even when the contract ends during the probationary period, and the maximum is set by statute and indexed each year by the Minister of Social Affairs and Employment. Our pages on the transition payment and on dismissal in the probationary period go into the detail, and our article on termination and notice periods covers the periods that apply when notice is given.
Deadlines, evidence and the mistakes that cost cases
Two time limits decide more dissolution disputes than the merits do. The first is the duty to complain in article 6:89 BW: a creditor who does not protest within a reasonable time after discovering a defect in performance, or after the moment it should reasonably have been discovered, loses every remedy in respect of that defect, dissolution included. What counts as reasonable depends on the contract and on how quickly the defect could be investigated, but silence is never safe. The second is prescription. Under article 3:311 BW the legal claim to have a contract dissolved lapses five years after the day on which the creditor became aware of the failure, and in any event twenty years after the failure occurred. Article 6:268 BW softens the effect: once that claim has prescribed, the ground for dissolution can still be raised as a defence against a demand for performance under the contract.
The mistakes we see most often are avoidable. Parties dissolve without ever having sent a notice of default, and discover in court that the debtor was never in default. They dissolve for a failure that is real but modest, and are met with the tenzij-defence. They send a letter that mixes dissolution with an offer to continue, leaving the legal position ambiguous. They forget that dissolution obliges them to hand back what they received, and have already resold or consumed it. Or they overlook a clause in their own general terms and conditions that made dissolution conditional on a longer cure period than the one they allowed.
A short checklist keeps the file in order: record the failure in writing as soon as you notice it, send a notice of default with a realistic period, put the dissolution in a separate, unambiguous letter, secure the evidence of your loss, and preserve whatever you have to return. If the counterparty is in financial difficulty, act quickly: dissolution against a party heading for insolvency is worth far less than a timely claim for performance or a properly secured settlement.
Common questions about contract dissolution
Can I dissolve a contract verbally
No. Article 6:267 BW requires a written declaration, and in electronic form only where the other party is reachable that way. A telephone call may be evidence that you complained, but it does not dissolve the contract. Put it in a letter or an email that says in so many words that the agreement is dissolved, and keep the proof of sending.
What is the difference between dissolution and annulment
Dissolution (ontbinding) is the remedy for a failure that occurs while a valid contract is running, and it works forward from the date of dissolution. Annulment (vernietiging) attacks the formation of the contract, for example because of fraud, duress, abuse of circumstances or a fundamental mistake, and removes it retroactively as if it had never been concluded. The consequences differ: after annulment everything performed was performed without legal ground, while after dissolution the parties owe each other restitution under articles 6:271 and following BW.
Do I always have to send a notice of default
Usually yes, because the right to dissolve depends on the debtor being in default. You may skip the notice where a strict contractual or statutory deadline has passed, where the obligation is to pay damages or arises from an unlawful act and is not met at once, where the debtor has told you it will not perform, or where performance has become impossible. Those exceptions are read narrowly, so when the situation is not obviously one of them, send the notice.
Can I claim damages as well as dissolving the contract
Yes. Article 6:277 BW gives the dissolving party a claim for the loss caused by the fact that the contract is unwound instead of performed, in addition to the mutual obligations to undo. Substantiate the loss with concrete figures; a court will not award a lump sum on assertion alone.
What if the other party disputes my dissolution
An extrajudicial dissolution takes effect the moment the declaration reaches the other party, but its validity can be tested afterwards. If the counterparty contests it and continues to demand performance, the dispute usually ends up before the civil court, which decides retrospectively whether the grounds were present. That risk is the main reason to build the file properly before you send the letter rather than after.
How Law and More can help
Dissolving a contract is a decision with consequences that are hard to reverse, and the difference between a dissolution that holds and one that backfires is usually a matter of preparation: the right ground, the right notice, the right wording and the right moment. Our contract lawyers assess whether the failure carries dissolution, draft the notice of default and the declaration, and take the matter to court or defend you against a dissolution declared by the other side.
