Breach of contract (wanprestatie) under Dutch law means that a party fails to perform a contractual obligation, or performs it late or improperly (a tekortkoming). The creditor can then claim performance, termination or damages. Damages are only due if the failure can be attributed to the debtor and, where performance is still possible, the debtor is in default (Article 6:74 Dutch Civil Code).
Breach of contract arises when you as a contracting party fail to meet your obligations as expected under the agreement. This legal concept covers a broad spectrum of failures: from a supplier delivering damaged goods to a contractor failing to complete a construction project on time. According to the Dutch Civil Code, every attributable failure obligates the debtor to compensate the creditor for damages. However, this obligation only applies when the failure can actually be attributed to the debtor and does not result from force majeure.
In Dutch contract law, breach of contract forms the legal foundation for recovering damages when contracting parties fail to fulfill their obligations. Entrepreneurs and individuals can invoke various legal remedies to protect their interests. The distinction between attributability and force majeure plays a central role in determining whether damages are owed. Moreover, understanding these principles helps prevent many contractual disputes from escalating to litigation.
Recognising a breach early and responding correctly protects your business interests. This article explains the legal framework, the remedies and practical strategies for handling contractual failures under Dutch law.
How does Article 6:74 Dutch Civil Code define breach of contract?
Article 6:74 Dutch Civil Code establishes that every failure to perform an obligation requires the debtor to compensate damages suffered by the creditor, unless the failure cannot be attributed to the debtor. This statutory provision forms the legal basis for liability in breach of contract cases.
Article 6:74 paragraph 1 Dutch Civil Code sets out the main rule: “Every failure in the performance of an obligation obliges the debtor to compensate the damage which the creditor suffers as a result, unless the failure cannot be attributed to the debtor.” Consequently, this provision creates a direct link between failure and obligation to pay damages. The legislator has thereby established a clear starting point for contractual liability in the Netherlands.
The second paragraph of Article 6:74 Dutch Civil Code adds an important condition: “Insofar as performance has not already become permanently impossible, paragraph 1 only applies with due observance of what is stipulated in the second section concerning the default of the debtor.” In other words, the debtor must be in default before the obligation to pay damages arises. Default generally arises when the creditor has sent a written notice of default (ingebrekestelling) giving the debtor a reasonable period to perform, and performance does not follow within that period (Article 6:82(1)). In some cases, default arises without a notice, for example when a fixed deadline expires (Article 6:83).
Subsequently, Article 6:75 Dutch Civil Code sets out the exception: a failure cannot be attributed to the debtor if it is not due to his fault and is not for his account by virtue of the law, a juristic act or generally accepted views. This is what Dutch law calls force majeure (overmacht). The debtor who relies on it must in principle prove the facts that support it.
Furthermore, under Article 6:76 Dutch Civil Code, a debtor who uses other persons to perform an obligation is liable for their conduct in the same way as for his own conduct. This means that businesses are responsible for their employees and subcontractors when these persons perform the contract. A law firm that engages an intern therefore remains liable for mistakes made by that intern in performing the client’s instructions.
Additionally, Article 6:77 Dutch Civil Code covers failures caused by unsuitable equipment or materials. If the debtor uses an unsuitable thing to perform the obligation, the resulting failure is attributed to him, unless that would be unreasonable in view of the contract, generally accepted views and the other circumstances of the case. An example is a transport company whose defective truck damages the goods during transport.
When must you send a notice of default under Dutch law?
As a rule, a notice of default is needed before you can claim damages or terminate the contract, as long as performance is still possible. It is not needed if performance has become permanently impossible, or where the law provides that default arises without notice (Article 6:83 Dutch Civil Code). For termination, temporary impossibility is also enough (Article 6:265(2)).
Under Article 6:82(1) Dutch Civil Code, default begins when the debtor has received a written notice that gives him a reasonable period to perform, and performance does not follow within that period. The notice informs the debtor about the failure, offers a final opportunity to perform and, once the period has expired without performance, places him in default. From that moment, the debtor owes damages for the delay. Without a valid notice of default, a claim for damages or termination may fail where a notice was required.
A legally valid notice of default must be in writing and must give the debtor a reasonable period to perform (Article 6:82(1)). What is reasonable depends on the circumstances, such as the nature of the obligation and whether the debtor has already had time to prepare. In practice, a good notice also describes the failure concretely, states which contractual obligation it concerns and announces which legal steps will follow if performance does not take place.
However, there are exceptions to the notice of default requirement under Dutch law. If performance has become permanently impossible, no default is required for damages (Article 6:74(2)). For example, when a photographer has missed the wedding, a notice of default no longer makes sense. Under Article 6:83, default also arises without notice when a fixed deadline for performance expires (unless the deadline was meant differently), when the creditor must conclude from a statement of the debtor that he will not perform, and for an obligation to pay damages that is not performed immediately.
Subsequently, there is a distinction between a notice of default and a liability notice (aansprakelijkstelling). A notice of default gives the debtor a final, reasonable period to perform. A liability notice only states that the debtor is held liable for the failure to perform. Under Article 6:82(2), a written liability notice is sufficient if the debtor is temporarily unable to perform, or if his attitude shows that a demand to perform would be pointless.
Furthermore, be aware of creditor’s default (schuldeisersverzuim). Under Article 6:58, the creditor is in default when performance is prevented because he does not give the necessary cooperation, unless this cannot be attributed to him. For example, when a contractor wants to renovate your building but you refuse to grant access. While you as creditor are in default, the debtor cannot be in default and any existing default of the debtor ends (Article 6:61). You may also not take enforcement measures (Article 6:62), and the debtor can claim reasonable costs caused by your default (Article 6:63).
What legal remedies exist for breach of contract under Dutch law?
The main remedies for breach of contract are claiming performance, claiming damages, suspending your own performance, terminating the contract and setting off mutual claims. A contractual penalty can apply if agreed. Procedural tools, such as summary proceedings and pre-judgment attachment, help you enforce or secure these rights. Each remedy has its own conditions.
Claiming performance (nakoming) is the most direct solution when performance is still possible. The competent court can order your counterparty to perform within a set period and, on request, attach a penalty payment (dwangsom) for each day or each breach of the order (Article 611a Dutch Code of Civil Procedure). For example, a supplier can be ordered to deliver ordered goods within 14 days, on penalty of a fixed amount per day. A penalty payment cannot be imposed on an order to pay money, and it is only forfeited after the judgment has been served. Performance cannot be ordered if it has become impossible.
Supplementary damages compensate costs you incur in addition to performance of the agreement. Consider storage costs for delayed delivery, extra labor costs due to project overruns, or transition damage when switching to another supplier. This form of damages accumulates with performance. An Amsterdam entrepreneur who had to hire additional staff due to delayed delivery can recover these wage costs from the debtor. In many cases, supplementary damages are awarded for temporary failures, provided you can demonstrate the causal connection between breach and costs.
Substitute damages (vervangende schadevergoeding) replace the performance itself. They are available if performance has become permanently impossible, or if the debtor is in default and you notify him in writing that you claim damages instead of performance (Article 6:87). No such conversion takes place if the failure is of minor importance. Substitute damages cover the value of the performance you did not receive and can include lost profits. Once the obligation has been converted, you can no longer claim performance.
Suspension of obligations (opschorting) is a way to put pressure on the other party without ending the contract. If your counterparty does not perform, you may suspend your own obligations under the same contract (Article 6:262). You may also suspend an obligation towards a party against whom you have a due claim, provided there is sufficient connection between the two (Article 6:52). In case of partial or improper performance, suspension is only allowed to the extent that the failure justifies it. If you suspend without a valid ground, you may yourself be in breach.
Termination of the agreement (ontbinding) ends the contractual obligations. Under Article 6:265(1), every failure in performance gives the other party the right to terminate the contract in whole or in part, unless the failure, given its special nature or minor importance, does not justify termination. Termination takes place by a written declaration or by a court decision (Article 6:267). It has no retroactive effect (Article 6:269), but performances already received must be undone (Article 6:271). If a performance cannot be returned, its value must be compensated (Article 6:272).
Set-off of claims (verrekening) offers a practical solution for mutual debts. If you have a claim against the same party to whom you owe money, you may set off the two (Article 6:127). For example: your supplier must refund € 10,000 for defective goods, while you still owe him € 7,000 for earlier deliveries. After set-off, he still owes you € 3,000. You must be entitled both to pay your debt and to enforce your claim, and set-off takes effect by a declaration to the other party. The law does not require that declaration to be in writing, but a written declaration is advisable as evidence.
Penalty clauses (boetebeding) oblige the debtor to pay a fixed sum if he fails to perform (Article 6:91). Unless agreed otherwise, the penalty replaces statutory damages, and you cannot claim both the penalty and performance of the obligation to which it relates (Article 6:92). For example, a contractor agrees to pay € 500 per day of delay, and the project runs 200 days late (€ 100,000). At the debtor’s request, the court can reduce the penalty, but only if fairness clearly requires this, and never below the damages due under the law (Article 6:94(1)).
Injunctive relief can prevent an imminent breach or stop an ongoing one. In urgent cases, you can start summary proceedings (kort geding), in which the preliminary relief judge can order a provisional measure (Article 254 Dutch Code of Civil Procedure). For example, when a former business partner threatens to breach a non-compete clause, or when a supplier announces that it will stop critical deliveries. Summary proceedings are usually much faster than proceedings on the merits, but the decision is provisional.
Pre-judgment attachment (conservatoir beslag) secures your claim before judgment. You need leave from the preliminary relief judge, who decides after a summary examination (Article 700 Dutch Code of Civil Procedure). You can attach bank accounts, inventory, real estate or receivables. Unless proceedings on the merits are already pending, you must start them within the period set by the judge, which is at least eight days after the attachment. A court fee (griffierecht) and bailiff costs are payable. Attachment can give strong negotiating power, but if your claim later proves unfounded, you can be liable for the damage the attachment caused.

How does Dutch law distinguish breach of contract from force majeure?
Breach of contract presumes attributable failure where the debtor is liable for damages, while force majeure involves non-attributable failure without damage obligation. This distinction therefore determines whether you are entitled to compensation for suffered damages.
Article 6:75 Dutch Civil Code defines when a failure is not attributable: when it is not due to the debtor’s fault and is not for his account by virtue of the law, a juristic act or generally accepted views. This definition creates the legal boundary between liability and exemption. The debtor, not the creditor, must prove the facts on which a force majeure defence is based.
Objective force majeure exists with external circumstances outside the debtor’s sphere of influence. Consider natural disasters, war, terrorist attacks, or government measures like lockdowns. During the COVID-19 pandemic, many entrepreneurs invoked force majeure for unfulfilled delivery obligations. However, this appeal succeeds in only a portion of cases, because under Article 6:75 the question is whether the failure is due to the debtor’s fault or is for his account by law, contract or generally accepted views. Courts consider, for example, whether alternative suppliers existed, whether the debtor could have taken precautions and whether the risk was foreseeable when the contract was concluded.
Conversely, subjective force majeure under Dutch law concerns circumstances on the debtor’s side that prevent performance. For example, serious illness of the debtor, bankruptcy of a key supplier, or theft of essential business assets. Courts then weigh heavily whether the debtor could have foreseen or prevented the circumstance. Problems with persons the debtor uses to perform the contract are for his account (Article 6:76), and many other business risks are too.
Moreover, contractual agreements can expand or limit the concept of force majeure. General terms and conditions often contain force majeure clauses qualifying specific situations as force majeure. For example, a transport company defining strikes, weather conditions, or traffic blockades as force majeure. However, courts test whether such clauses are reasonable according to Article 6:233 sub a Dutch Civil Code. An unreasonably onerous clause can be annulled (vernietigd), especially in consumer transactions. Business-to-business agreements receive more freedom: a company such as an NV or BV that has most recently published its annual accounts (whatever its size), a party with 50 or more employees, and a party that itself repeatedly uses the same or similar general terms cannot invoke this ground at all (Article 6:235(1) and (3)).
Additionally, temporary impossibility does not automatically lead to permanent force majeure. When performance is only temporarily prevented, for example by short-term shortages or transport problems, the debtor must still perform once the impediment is removed. Only when the delay lasts so long that performance loses its purpose does performance become permanently impossible. How long that takes depends on the nature of the obligation and the circumstances; for time-sensitive obligations such as event catering, a short delay can be decisive. Note that termination is possible even if the failure is not attributable to the debtor, and in case of temporary impossibility no default is required (Article 6:265(2)).
What is the difference between obligation of means and obligation of result in the Netherlands?
With an obligation of result, the debtor must achieve a concrete result, while with an obligation of means, only proper effort is expected. This distinction determines when attributable breach of contract exists and how easily you can prove this failure.
Obligations of result require that an agreed final result is realized. Typical examples are purchase agreements, construction contracts, and delivery agreements. A contractor who builds an office building must deliver this building according to specifications. If he does not, a failure automatically exists without you needing to prove culpability. Many commercial agreements contain obligations of result.
Conversely, obligations of means only require that the debtor does his best to achieve a certain goal. Consider legal services, medical treatments, or architectural assignments. A lawyer in Amsterdam does not guarantee victory in litigation but must act competently and carefully. With obligations of means, you as creditor must prove that the debtor did not exercise required diligence. This burden of proof is considerably heavier, often requiring expert testimony in professional liability cases.
Furthermore, the duty of care serves as the assessment framework for obligations of means. Under Article 7:401 Dutch Civil Code, a service provider must observe the care of a good service provider. In practice, courts ask whether the professional acted as a reasonably competent and reasonably acting professional in the same field would have done. IT specialists, accountants and consultants fall under this standard. Not every mistake or deviation from best practice is a breach; the question is whether a reasonably competent peer could have acted in the same way.
Additionally, contracts can combine both types of obligations. For example, an IT implementation project where the supplier must both deliver software (obligation of result) and advise on implementation (obligation of means). With such mixed contracts, each obligation must be assessed separately for whether it involves means or result. This assessment requires interpretation under the Haviltex standard: what meaning could the parties reasonably attribute to the contract terms in the circumstances, and what could they reasonably expect from each other (Supreme Court 13 March 1981, ECLI:NL:HR:1981:AG4158). Courts apply contextual analysis considering industry customs, relative expertise, and explicit contractual language.
What damages can you recover for breach of contract under Dutch law?
For breach of contract, you can recover: actual loss, lost profits, extrajudicial collection costs, and in exceptional cases non-pecuniary damages. Total compensation must restore you to the position you would have occupied without the breach.
Actual loss includes all costs you actually incurred as direct consequence of the failure. For example, costs for replacement deliveries at higher prices, storage costs for delayed acceptance, or repair costs for defective delivery. An Amsterdam retailer who must urgently purchase from a more expensive supplier due to breach can recover this price difference. In most breach of contract cases, actual loss is awarded, provided you maintain adequate documentation of expenses and causation.
Additionally, lost profits (gederfde winst) are part of the recoverable financial loss (Article 6:96(1)). Under Article 6:98, only damage that is so connected with the breach that it can reasonably be attributed to the debtor as a consequence of it is recoverable. Whether the damage was foreseeable is one of the factors. For example, an event organiser who must cancel a concert because the headliner breaches the contract can claim the lost ticket revenue. If the amount cannot be determined precisely, the court estimates it (Article 6:97), and future loss can be assessed by weighing the chances (Article 6:105). You still need to substantiate the loss, for example with historical figures or advance bookings.
Moreover, extrajudicial costs can be claimed under Article 6:96(2): reasonable costs to establish damage and liability, and reasonable costs to obtain payment out of court. For contractual payment claims, the Extrajudicial Collection Costs Decree (Besluit vergoeding voor buitengerechtelijke incassokosten, BIK) sets a sliding scale: 15% of the first € 2,500 of the principal, lower percentages above that, with a minimum of € 40 and a maximum of € 6,775 (Article 2 BIK). These rules are mandatory in favour of consumers (Article 6:96(5)). In a commercial contract, at least € 40 is due without a reminder once the payment deadline has passed (Article 6:96(4)).
Additionally, delay damages exist as specific damage category for late performance. These damages compensate for time loss between agreed and actual performance. Consider statutory commercial interest on invoices paid too late (Article 6:119a). For commercial contracts it is the ECB refinancing rate plus eight percentage points, set for each half year (Article 6:120(2)): 10.4% per year from 1 July to 31 December 2026. For other obligations, delay damages may consist of rental costs for temporary replacement or operational losses due to delayed delivery. Delay damages are awarded in many contractual disputes, particularly when delays cause demonstrable financial harm beyond ordinary inconvenience.
Finally, non-pecuniary damages (smartengeld) are only available where the law provides for them (Article 6:95(1)). Article 6:106 applies to contractual liability too. It grants compensation in fairness if the liable person intended to cause such harm, if the injured person suffered physical injury, was harmed in his honour or reputation, or was otherwise affected in his person. In commercial disputes this rarely applies, and a company cannot suffer physical or mental harm. Whether, for example, a photographer who loses wedding photos must pay non-pecuniary damages depends on the circumstances of the case.

When should you consider terminating a contract in the Netherlands?
Under Article 6:265(1) Dutch Civil Code, every failure in performance gives the other party the right to terminate the contract in whole or in part, unless the failure, given its special nature or minor importance, does not justify termination. As long as performance is still possible, the debtor must first be in default (Article 6:265(2)).
Severity of the breach matters because of the exception in Article 6:265(1). The starting point is that any failure allows termination; the debtor must show that the failure is of such minor importance, or of such a special nature, that termination is not justified. For example, one defective item in a series of 100 may not justify terminating the whole contract, while 40% defective products probably does. Relevant factors include the extent of the non-performance, whether it concerns an essential obligation, whether it can be remedied and whether it shows systematic unreliability. Partial termination is also possible.
Permanent impossibility means that you can terminate without first sending a notice of default (Article 6:265(2)). When a unique painting sold under a contract burns in a fire, performance has become impossible. The exception for failures of minor importance still applies. To terminate out of court, you must send a written declaration to your counterparty (Article 6:267(1)); you can also ask the court to terminate the contract (Article 6:267(2)).
Delay and temporary impossibility require more careful assessment. If performance is merely late but still possible, the debtor must usually be in default first: you send a notice of default, and you can terminate only if he does not perform within the set period. If performance is temporarily impossible, termination does not require default (Article 6:265(2)). Where a fixed deadline was agreed, default can arise without a notice when the deadline expires (Article 6:83(a)). For example, carnival costumes delivered after carnival are of no use.
Repeated minor breaches can together justify termination, even when each failure on its own seems insignificant. A supplier who is consistently two or three days late with monthly orders may not commit a serious breach each time. After months of systematic delays, especially after warnings, the pattern of unreliability can make termination justified.
Anticipatory breach allows you to act before performance is due. Under Article 6:80(1), the consequences of non-performance arise early if it is certain that proper performance will be impossible, if you must conclude from a statement of the debtor that he will not perform, or if you have good grounds to fear non-performance and the debtor does not respond to a written demand, stating those grounds, to confirm within a reasonable period that he will perform. For example, a contractor who states that he cannot meet the agreed specifications. This prevents you from continuing preparations for a contract that will fail.
How do you calculate damages for breach of contract in the Netherlands?
Damages are generally calculated by comparing your actual position with the position you would have been in if the contract had been properly performed. Only damage that can reasonably be attributed to the breach is recoverable (Article 6:98 Dutch Civil Code), and you must substantiate the loss and the causal link.
The difference method compares what you would have had with what you actually have. Article 6:95 Dutch Civil Code provides that financial loss is compensated, and other loss only where the law allows it. For example, you agreed to buy goods for € 10,000 to resell them for € 15,000. The seller breaches. If you buy replacement goods elsewhere for € 12,000 and still make the resale, your loss is the extra purchase cost of € 2,000. If instead you lose the resale altogether, your loss is the lost profit of € 5,000. You cannot claim both for the same transaction, because that would compensate the same loss twice.
Attribution of damage under Article 6:98 Dutch Civil Code limits damages to loss that can reasonably be attributed to the debtor as a consequence of the breach, taking into account the nature of the liability and of the damage. Foreseeability plays a role in that assessment, but it is not a separate statutory test. Direct damage, such as replacement costs, is usually attributed. Remote consequential loss may not be: a software supplier who could not know that your business depended entirely on his product may not be liable for large business interruption losses. Many contracts also limit liability for indirect or consequential damage.
Causation requires a connection between the breach and the damage claimed. First, the damage would not have occurred without the breach (the “but-for” test). For example, if your business was already failing before the supplier’s breach, you cannot attribute all losses to that breach. Second, the damage must be attributable under Article 6:98. If circumstances for which you are responsible contributed to the damage, such as failing to limit your losses, the damages are reduced (Article 6:101). For instance, if you could have bought replacement goods at € 11,000 but waited until the price rose to € 13,000, the court may reduce your damages by € 2,000.
Documentation requirements demand concrete evidence of losses. Retain invoices, contracts, correspondence, financial statements, and expert assessments proving damages. For actual loss, provide receipts for replacement purchases, storage costs, or repair expenses. For lost profits, demonstrate historical earnings, advance bookings, or market analyses showing probable profits. Dutch courts reject a portion of damage claims due to insufficient evidence, particularly for lost profit calculations lacking objective support.
Mitigation obligation under Article 6:101 Dutch Civil Code requires you to limit damages where reasonably possible. You cannot allow losses to accumulate when simple actions would prevent further damage. For example, when a supplier fails to deliver, you must reasonably attempt to find alternative suppliers rather than simply waiting and claiming increasing damages. However, mitigation does not require extraordinary effort or expense. Courts reduce damages when claimants fail to take obvious mitigation opportunities.
Frequently asked questions about breach of contract under Dutch law
Is breach of contract the same as wanprestatie?
Yes. Wanprestatie is the common Dutch term for a failure in the performance of a contractual obligation (tekortkoming). Every failure allows you to claim performance or, in principle, to terminate the contract; damages require that the failure can be attributed to the debtor (Articles 6:74 and 6:265 Dutch Civil Code).
Do I always have to send a notice of default first?
No. A notice of default is not needed if performance has become permanently impossible, if a fixed deadline for performance has expired (unless the deadline was meant differently), or if the debtor has stated that he will not perform (Articles 6:74(2) and 6:83). For termination, temporary impossibility is also enough (Article 6:265(2)). In other cases, send a written notice with a reasonable period to perform (Article 6:82(1)).
Can I terminate a contract for a minor breach?
In principle every failure allows termination, but not if the failure, given its special nature or minor importance, does not justify it (Article 6:265(1)). You can also terminate only part of the contract. Termination takes place by a written declaration or by a court decision (Article 6:267).
Can a Dutch court reduce a contractual penalty?
Yes, at the debtor’s request, but only if fairness clearly requires it. The court cannot award less than the damages due under the law (Article 6:94(1)). Unless agreed otherwise, the penalty replaces statutory damages (Article 6:92(2)).
How much interest can I claim on a late payment between businesses?
The statutory commercial interest rate (Article 6:119a). It equals the ECB refinancing rate plus eight percentage points and is set for each half year (Article 6:120(2)). From 1 July to 31 December 2026 it is 10.4% per year.
