How Do You Write a Demand Letter Under Dutch Law?

Published on 27 December 2022 · Last updated 24 October 2026

Under Dutch law, a demand letter (ingebrekestelling) is a written notice that gives the debtor a reasonable period to perform. If performance does not follow within that period, the debtor is in default (verzuim) (Article 6:82(1) of the Dutch Civil Code (DCC)). Default is in principle required before the creditor can claim statutory interest (statutory commercial interest runs from the agreed payment date without default), damages where performance is still possible, and termination of the contract.

As a Dutch debt collection lawyer, I explain below what a demand letter must contain, when you do not need one, how it interrupts the limitation period and how to prove that the debtor received it. Our team also advises on advantages disadvantages preliminary attachment under Dutch law.

What does a Dutch demand letter look like?

What is the purpose of a demand letter?

A demand letter can have two legal functions under Dutch law. It puts the debtor in default if performance does not follow within the period set (Article 6:82(1) DCC). It can interrupt the limitation period (Article 3:317 DCC). If the debtor is a consumer who is already in default, a separate reminder with a 14-day payment period is also required before extrajudicial collection costs can be charged (Article 6:96(6) DCC). In all cases, the letter should state the reasons for the demand clearly and concisely.

Under Dutch law, a demand letter is an effective tool to initiate the resolution of disputes and to seek payment or other forms of relief. It serves as a formal notice to the other party, notifying them of their obligations and the consequences of their non-compliance.

In the demand letter, it is essential to outline the specific terms and conditions of the contract that have been violated or not fulfilled. This includes identifying the relevant clauses and providing evidence of the breach, such as correspondence, invoices, or other supporting documents. The letter should also clearly state the desired outcome, whether it is the payment of a certain amount, termination of the agreement, or any other form of resolution.

Moreover, the demand letter can serve as a precursor to legal action. By clearly articulating the reasons for the demand and the potential consequences of non-compliance, it can demonstrate to the other party that the matter is being taken seriously and that legal action may be pursued if necessary. Therefore, it is crucial to ensure that the demand letter is written professionally, adhering to the formalities and requirements of Dutch law.

Seeking legal advice before drafting the letter can help increase the chances of a successful outcome and provide guidance on the specific legal requirements.

What constitutes expiration and interruption of claims under Dutch law?

A claim for performance of a contractual obligation to give or to do becomes time-barred five years after the start of the day following the day on which it became due and payable (Article 3:307(1) DCC). A claim for damages becomes time-barred five years after the injured party became aware of both the damage and the liable person, and in any case twenty years after the event that caused the damage (Article 3:310(1) DCC). Interruption (stuiting), other than by a court claim that is granted, starts a new limitation period equal to the original one but not longer than five years, and never ending earlier than the original period would have (Article 3:319 DCC).

Bringing a claim in court or in arbitration, for example in a debt collection procedure started by a Dutch debt collection attorney, interrupts the limitation period (Article 3:316(1) DCC). For a claim to performance, such as payment of an invoice, a written demand also interrupts it (Article 3:317(1)). This also applies to a claim for damages (Supreme Court, ECLI:NL:HR:2014:766). For other legal claims, such as a claim to terminate or annul a contract, a written demand only interrupts the limitation period if it is followed within six months by legal action (Article 3:317(2)).

Which requirements must a demand letter meet?

A demand letter must meet two sets of requirements. To put the debtor in default, it must be in writing and give the debtor a reasonable period to perform; the debtor is in default if performance does not follow within that period (Article 6:82(1) DCC). To interrupt the limitation period, it must be a written demand or a written communication in which the creditor unambiguously reserves its right to performance (Article 3:317(1) DCC).

In practice, the letter should therefore identify the claim precisely, for example by invoice number, date and amount, so that the debtor cannot misunderstand which claim is meant.

In addition to a clear statement of the claim, the demand letter should also specify the exact amount owed. It should leave no doubt as to the creditor’s entitlement to this specified amount. This clarity not only aligns with legal standards but also serves as a strong and persuasive communication tool. Furthermore, the demand letter should include a clear reservation of rights by the creditor to claim the specified amount. This reservation reinforces the creditor’s position and intentions, indicating that they are prepared to take legal action if necessary to recover the debt.

In short: the letter should leave no doubt about which claim is meant and that the creditor still requires payment or performance. Announcing legal action is common, but the law does not require it for interruption.

When is the debtor in default without a demand letter?

A demand letter is not always needed. The debtor is in default without one (Article 6:83 DCC):

• when a fixed period for performance expires without performance, unless that period has a different purpose;
• when the obligation arises from a tort, or is an obligation to pay damages for breach of contract, and it is not performed immediately;
• when the creditor must conclude from a statement of the debtor that the debtor will not perform.

If the debtor is temporarily unable to perform, or its attitude shows that a demand would be pointless, a written notice holding the debtor liable for the failure to perform is sufficient (Article 6:82(2) DCC). Even where the law does not require it, a demand letter is useful as evidence and to interrupt the limitation period.

Who must prove the letter was delivered?

A crucial and often underestimated aspect of utilizing a demand letter in Dutch legal proceedings is the onus of proving its delivery to the intended recipient.

In legal matters, ensuring that your communication is not only sent but also received and acknowledged is of paramount importance.

A demand letter only has effect once it has reached the debtor (Article 3:37(3) DCC). As a rule, the party that relies on the letter must prove this if the debtor disputes receipt (Article 150 of the Dutch Code of Civil Procedure). There is an exception: a letter that did not reach the debtor still has effect if this is due to the debtor’s own actions, to persons for whom it is responsible, or to other circumstances concerning the debtor that justify that it bears the risk (Article 3:37(3)). In practice, creditors send important letters by registered mail (aangetekende post), which provides a record of delivery.

Email can also be used, in particular where the parties have communicated by email before. Proving that an email reached the debtor can, however, be harder than proving delivery of a registered letter. Many creditors therefore send the letter both by email and by registered mail.

In conclusion, when sending a demand letter in Dutch legal proceedings, it is essential to not only draft a compelling and legally sound document but also to take proactive measures to prove its delivery, whether through registered mail or electronic means, to ensure its effectiveness in pursuing your legal claims.

How do you address the debtor?

When addressing the recipient of a demand letter under Dutch law, it is crucial to verify the correct address, especially for companies. Ensuring that the letter reaches the intended recipient is essential for the effectiveness of the demand.

In the case of companies, it is important to address the letter to the appropriate person or department responsible for handling such matters. This helps to avoid any delays or confusion caused by the letter being forwarded to the wrong individual.

To address the recipient effectively, it is advisable to tailor the demand letter to their role and responsibilities. This ensures that the recipient understands their obligations and the potential consequences of non-compliance. It is also important to ensure that the letter reaches the decision-maker rather than getting lost in bureaucratic processes. Therefore, it may be necessary to do some research or make inquiries to identify the right person to address the demand letter to. In addition to traditional mail, demand letters can also be sent by email, in particular if the parties have communicated by email before. However, it is important to ensure that the recipient’s email address is accurate and up-to-date.

What breach should the letter describe?

To effectively address a breach situation under Dutch law, it is essential to have a clear understanding of the specific breach and its implications.

Breach occurs when one party fails to fulfill their obligations under a contract, which can include non-payment, non-performance, or violation of terms and conditions. Understanding the nature and consequences of the breach is crucial for determining the appropriate legal action to take. In the context of writing a demand letter under Dutch law, the understanding of the breach plays a pivotal role. The demand letter serves as a formal communication to the breaching party, outlining the specific breach and requesting appropriate remedies, such as compensation for damages or termination of the agreement. It is important to clearly state the reasons for the demand, providing evidence of the breach and its impact. Dutch law provides certain rights and remedies for breach situations. The specific legal provisions may vary depending on the nature of the breach and the terms of the contract. Seeking legal advice is advisable to ensure compliance with Dutch law and to increase the chances of a successful outcome.

What happens if the debtor does not pay?

If the debtor does not perform within the period set in the letter, it is in default (Article 6:82(1) DCC). From that moment, the creditor can rely on the remedies that require default. Where performance is not yet permanently impossible, damages for breach of contract can only be claimed with due regard to the rules on default (Article 6:74(2) DCC), and, unless performance is permanently or temporarily impossible, the right to terminate the contract only arises once the debtor is in default (Article 6:265(2) DCC).

The main consequences of default are:

Consequence of default	Legal basis
Statutory interest on a late payment: 4% per year since 1 January 2026. For commercial contracts, statutory commercial interest applies, 10.4% per year from 1 July to 31 December 2026, which runs from the day after the agreed payment date without any demand	Articles 6:119, 6:119a and 6:120 DCC
Damages for the breach of contract, unless the breach cannot be attributed to the debtor	Article 6:74 DCC
Right to terminate the contract in whole or in part, unless the breach, given its special nature or minor importance, does not justify this	Article 6:265 DCC
Right to claim substitute damages instead of performance, by written notice to the debtor	Article 6:87 DCC
Reasonable costs of collection outside court	Article 6:96(2)(c) DCC and the Extrajudicial Collection Costs Decree

A letter that does not meet the requirements may fail to put the debtor in default, which can delay these remedies. If the debtor still does not pay after a valid demand, the next step is usually Dutch debt collection proceedings.

Which interest and collection costs can you claim?

Statutory interest. In non-commercial cases, the debtor owes statutory interest (wettelijke rente) from the moment it is in default (Article 6:119 DCC). The rate has been 4% per year since 1 January 2026 (Statutory Interest Decree).

Commercial interest. In a commercial contract between businesses, statutory commercial interest (wettelijke handelsrente) runs from the day after the agreed payment date. If no payment date was agreed, it runs by operation of law, as a rule from 30 days after the debtor received the invoice (Article 6:119a(1) and (2) DCC). The rate is the ECB main refinancing rate before the start of each half-year plus eight percentage points (Article 6:120(2) DCC). From 1 July to 31 December 2026 it is 10.4% per year (ECB rate of 2.40% plus eight points; ECB key interest rates).

Collection costs. Reasonable costs of collection outside court can be claimed as damages (Article 6:96(2)(c) DCC). For contractual payment obligations, the Extrajudicial Collection Costs Decree (Besluit vergoeding voor buitengerechtelijke incassokosten, BIK) sets the amount (Article 1 BIK): 15% of the first €2,500 of the principal, 10% of the next €2,500, 5% of the next €5,000, 1% of the next €190,000 and 0.5% of the remainder, with a minimum of €40 and a maximum of €6,775 (Article 2 BIK).

• Business debtors: in a commercial contract, at least €40 is owed without any demand from the day after the payment date (Article 6:96(4) DCC). Businesses can agree on a different arrangement for collection costs, but not one that goes below this €40 to the detriment of the creditor.
• Consumer debtors: the rules cannot be set aside to the detriment of the consumer (Article 6:96(5)). The costs only become due after the consumer, once in default, has been reminded without result to pay within 14 days, starting the day after the consumer received the reminder (Supreme Court 25 November 2016, ECLI:NL:HR:2016:2704), with a statement of the consequences of non-payment, including the costs claimed (Article 6:96(6)).

Which rights does the creditor have?

The creditor’s entitlements and intended result are crucial aspects to consider when addressing their rights and desired outcome in a demand letter under Dutch law. It is important to understand the creditor’s rights within the legal framework and tailor the desired outcome accordingly.

Here are five key considerations to keep in mind:

• Legal rights: The demand letter should outline the creditor’s legal rights in the specific context of the case, highlighting any relevant Dutch laws or regulations that support their position.
• Contractual obligations: If the dispute arises from a contractual relationship, the letter should clearly articulate the creditor’s rights and obligations as stipulated in the contract.
• Desired outcome: The creditor should specify their desired outcome in the demand letter, whether it is seeking financial compensation, termination of the agreement, or another resolution that aligns with their goals.
• Reasonable expectations: It is important to assess the creditor’s desired outcome in light of the circumstances and the applicable legal principles to ensure it is reasonable and achievable.
• Legal advice: Seeking legal advice is crucial to understanding the creditor’s rights and determining the appropriate desired outcome. An experienced lawyer can guide the best approach to achieve a favorable result.

Which language and tone should you use?

When drafting a demand letter under Dutch law, it is important to maintain a professional and respectful tone while clearly expressing the creditor’s requirements.

The language and tone of the letter play an important role in getting the creditor’s demands across. Dutch law does not prescribe a language for a demand letter. To avoid any debate about whether the debtor understood it, write in Dutch or in a language the debtor clearly understands, such as the language of the contract or of earlier correspondence.

To ensure clarity and precision in the communication, it is advisable to avoid using aggressive language or making threats in the demand letter. Instead, the letter should adopt a formal and professional tone, maintaining courtesy and respect throughout. This will help to establish a cooperative and constructive atmosphere, facilitating a more amicable resolution.

To maintain conciseness and clarity, the demand letter should be written directly and assertively. It should clearly state the demand for payment or action, leaving no room for ambiguity or confusion. Using a table can be a useful tool to organize and present the creditor’s requirements in a structured and easy-to-follow format.

Should you sign and date the demand letter?

Signing and dating the demand letter is good practice. Article 6:82(1) DCC requires the demand to be in writing, and a signed and dated letter avoids discussion about who sent it and when.

The date on the letter shows when it was sent, but not when it was received. The period for performance should therefore be long enough to allow for delivery, and you should keep proof of delivery (Article 3:37(3) DCC).

When signing and dating the demand letter under Dutch law, it is important to follow these guidelines:

• Print your full name and position in the company.
• Sign the letter. If you send it by email, attach the signed letter as a PDF.
• Include the date of signing, which should be the same as the date on the letter.
• If the letter is being sent on behalf of a company, include the company’s name and address.
• Ensure that the signing and dating are done before the letter is sent to the recipient.

Frequently asked questions about demand letters under Dutch law

Do you always need a demand letter before claiming damages or terminating a contract?

Not always. Where performance is still possible, damages for breach and termination in principle require default (Articles 6:74(2) and 6:265(2) DCC), and default usually requires a demand letter (Article 6:82(1)). No demand letter is needed in the cases of Article 6:83 DCC, for example when a fixed deadline for performance has expired.

How long should the payment period in a Dutch demand letter be?

The law requires a reasonable period (Article 6:82(1) DCC) but does not fix a number of days. What is reasonable depends on the circumstances, such as the kind of performance. For consumer debtors, collection costs can only be charged after a reminder with a 14-day payment period (Article 6:96(6)).

Does a demand letter stop the limitation period?

It interrupts it. For a claim to performance, such as payment of an invoice, a written demand interrupts the limitation period (Article 3:317(1) DCC). This includes a claim for damages. For other legal claims, such as termination or annulment of a contract, it only does so if legal action follows within six months (Article 3:317(2)). A new period then starts, not longer than five years (Article 3:319).

Which interest rate applies to late payment in the Netherlands?

Statutory interest is 4% per year since 1 January 2026. For commercial contracts, statutory commercial interest applies: 10.4% per year from 1 July to 31 December 2026 (ECB main refinancing rate plus eight percentage points, Article 6:120(2) DCC). Commercial interest runs from the day after the agreed payment date (Article 6:119a(1)).

Can you charge collection costs in a demand letter?

Yes, as damages (Article 6:96(2)(c) DCC). For contractual payment obligations, the BIK decree sets a sliding scale with a minimum of €40 and a maximum of €6,775 (Article 2 BIK). Against a business, at least €40 is owed in a commercial contract without any demand (Article 6:96(4)); against a consumer, a 14-day reminder is required first (Article 6:96(6)).
