Demand letter generator (Dutch law)

What is a demand letter under Dutch law?

A demand letter is a written request from a creditor to a debtor to make an outstanding payment. Dutch law recognises several types of demand letters, each with a different legal function and consequences. The right choice depends on the nature of the relationship (consumer or business), the content of the original agreement, and how far the matter has already escalated.

1. Payment reminder

The payment reminder is a friendly first follow-up, typically sent 7 to 14 days after the due date. It has no statutory effect: the debtor is not placed in default merely by receiving the reminder, and at this stage no statutory interest or extrajudicial collection costs can yet be claimed. In practice, however, the reminder is often enough: many debtors pay after a first reminder, provided it is worded politely and professionally.

Payment reminder example and drafting

A good payment reminder states the invoice number, the outstanding amount, the original due date and a new, short payment term with clear payment instructions. The tone stays friendly: assume that payment has simply been overlooked. This tool drafts a payment reminder containing these elements automatically, free of charge; select template 1 in the generator above.

2. 14-day notice letter for consumers (Article 6:96(6) DCC)

The 14-day notice letter is a statutory requirement whenever a creditor wants to claim extrajudicial collection costs from a consumer. Without this notice — or with a notice that does not meet the formal requirements — the court will reject the claim for collection costs. Drafting this letter carefully is therefore essential to the success of any later collection procedure.

Dutch Supreme Court case law imposes strict requirements on the 14-day notice letter:

• The letter must give a payment term of at least fourteen days after receipt (not from the date of the letter). This tool uses the legally correct wording by default: ‘within fourteen days after receipt of this letter’.
• The specific amount of extrajudicial collection costs that becomes due once that term has lapsed unused must be stated explicitly (Dutch Supreme Court 25 November 2016, ECLI:NL:HR:2016:2704, Lindorff/Nazier).
• No collection costs may be claimed during the fourteen-day term; only after it has lapsed unused.

The tool generates a 14-day notice letter that meets these three requirements and calculates the collection costs amount automatically under the statutory scale.

3. Final demand

The final demand is the closing letter with which the creditor announces that legal proceedings will follow. It sets out the full claim: principal amount, accrued statutory interest, any contractual interest or contractual penalty up to the date of the letter, and any extrajudicial collection costs due. The final demand gives the debtor a short final term (often 7 days) to pay voluntarily, failing which court proceedings or a collection agency will be engaged. In practice, a well-substantiated final demand often still results in payment, because it is the first time the debtor sees, in black and white, the total amount owed and the concrete prospect of procedural costs.

Writing a final demand: example and structure

A final demand always contains the same elements: a list of the outstanding invoices, an itemised calculation of the principal, interest and any collection costs, a final payment term of five to seven days, and an explicit announcement of legal steps if payment is not made. This tool drafts a final demand with a complete, automatically calculated breakdown; select template 3 in the generator above.

Statutory interest, commercial interest, contractual interest or penalty: what applies when?

An unpaid claim usually involves more than just the principal amount. Compensation for the passage of time is anchored in Dutch law in four different ways. The tool supports each of these bases in the final demand.

• Statutory interest (Article 6:119 DCC) applies as the default rate on default when the parties have agreed nothing else. It applies to virtually all claims, including consumer claims. Set every six months.
• Statutory commercial interest (Article 6:119a DCC) applies to commercial transactions between businesses, or between a business and a public authority. Significantly higher than ordinary statutory interest.
• Contractual interest can be agreed between the parties in place of statutory interest. Valid as long as the agreement was validly formed and, for consumers, is not unreasonably onerous within the meaning of Article 6:233 DCC.
• Contractual penalty (Article 6:91 DCC) is an agreed amount due upon non-performance, regardless of the actual loss suffered. Common in general terms and conditions of industry models such as the Dutch commercial-lease model (ROZ) or the Metaalunie terms.

Which basis applies depends on what the parties have agreed and which terms have been declared applicable to the agreement. If in doubt, the creditor falls back on statutory interest.

Contractual interest for late payment

Parties can agree an interest rate other than the statutory rate in their agreement. This is common in commercial contracts, loan agreements or factoring arrangements. Contractual interest replaces statutory interest from the moment default occurs.

A few points to note about contractual interest:

• The agreement must have been validly formed (offer, acceptance and, for standard terms, the duty to provide information under Article 6:233/234 DCC).
• In agreements with consumers, any contractual interest arrangement is tested against the Unfair Contract Terms Directive (Directive 93/13/EEC, implemented in Article 6:233 DCC). A rate that deviates sharply, for example 1.5 % per month, can be annulled or disapplied by the court of its own motion.
• Between businesses, greater freedom of contract applies, but even there an unreasonably high rate can be moderated on the basis of reasonableness and fairness (Article 6:248(2) DCC).
• Compound interest (interest on interest) is permitted in B2B relationships if explicitly agreed, but exceptional in consumer relationships.

The tool lets you enter a contractual rate manually or choose a predefined clause from general terms and conditions.

Penalty clauses in general terms and conditions

A penalty clause (Article 6:91 DCC) is a predetermined amount due upon non-performance, instead of or in addition to the loss actually suffered. Well-known examples are the Dutch model terms for the lease of office and retail space (ROZ) and certain industry terms for suppliers.

Key legal frameworks:

• The penalty in principle applies instead of statutory interest and any damages, unless agreed otherwise (Article 6:92(2) DCC).
• The court may moderate a penalty if fairness clearly requires this (Article 6:94 DCC). The test weighs the difference between the agreed penalty and the actual loss, the relationship to the creditor’s interest, and any other special circumstances.
• In consumer agreements, the penalty clause is also tested against unfair-terms case law. The Dutch Supreme Court regularly holds that consumer penalty clauses are disproportionate and therefore voidable.
• Combining a penalty with extrajudicial collection costs can be seen as double compensation for the same delay-related loss. The court may reduce one or both claims.

When using this tool: state the penalty in the final demand explicitly as a penalty, not as interest. Avoid mentioning the possibility of judicial moderation in the letter itself; that would weaken your position. The tool shows the legal framework only in the interface.

Demand letters for sole traders and SMEs: collection letters between businesses

Different rules apply to a sole trader or an SME with an unpaid invoice against a business customer than against a consumer. The 14-day notice letter is not mandatory against a business debtor: that formal requirement protects consumers only. Between businesses, the claim for extrajudicial collection costs becomes due as soon as the debtor is in default and a demand has lapsed unused, and the parties may agree a different fee in their agreement or general terms.

In addition, a commercial transaction is subject to the higher statutory commercial interest (Article 6:119a DCC) instead of ordinary statutory interest. A sole trader sending a collection letter to a business client should therefore select ‘business’ as the counterparty in this tool, after which the correct interest regime and collection costs basis are applied automatically. A final demand with a full breakdown of the principal, commercial interest and collection costs is often the most effective last step before a collection procedure in a B2B context.

Step-by-step: from invoice to court summons

The collection process runs in five steps. Each step has its own letter type and legal consequence.

1. Invoice sent with a payment term

   The invoice states a payment term, commonly fourteen or thirty days. A clear, sufficiently definite term on the invoice or in the general terms can qualify as a fatal deadline.

2. Fatal deadline lapses (Article 6:83(a) DCC)

   If a fatal deadline lapses unused, default occurs automatically by operation of law. From that moment statutory interest runs, without any separate notice of default being required.

3. Payment reminder (optional)

   A friendly first reminder, typically seven to fourteen days after the due date. No statutory effect, but often sufficient in practice. Draft this with template 1.

4. 14-day notice letter or formal demand

   Against a consumer, the 14-day notice letter is a statutory requirement before collection costs can be claimed (Article 6:96(6) DCC). Against a business, a formal demand with a short term suffices.

5. Final demand and announcement of legal proceedings

   The final demand gives a final term of five to seven days and announces court proceedings, with a full breakdown of the principal, interest and collection costs. Court proceedings follow after that.

Extrajudicial collection costs: the statutory scale

The amount of extrajudicial collection costs is set by law through a degressive scale. The percentage decreases as the principal amount increases. The minimum is € 40 and the absolute maximum is € 6,775.

Source: Decree on Compensation for Extrajudicial Collection Costs, Article 6:96 DCC.

Calculating collection costs

The tool automatically calculates the extrajudicial collection costs on the outstanding principal under the scale above, adds the brackets cumulatively, and applies the statutory minimum of € 40 and maximum of € 6,775. In the 14-day notice letter, the specific collection costs amount must be stated, as required by the Dutch Supreme Court (Lindorff/Nazier). You do not need to apply the scale manually; select the letter type and the tool performs the calculation.

Eight common mistakes in a demand letter

The following mistakes regularly lead courts to reject a claim for interest or collection costs in practice.

1. The term runs from the date of the letter instead of from receipt. Against a consumer, this costs the entire collection costs claim.
2. The collection costs amount is not stated specifically in the 14-day notice letter, but only refers to the statutory scale.
3. The demand is sent before the payment term has lapsed, so the debtor is not yet in default.
4. Statutory interest is claimed where a B2B claim actually attracts the higher commercial interest (Article 6:119a DCC).
5. There is no proof of dispatch or receipt; for the 14-day notice letter, receipt determines when the term starts.
6. A penalty from general terms is combined with statutory interest without an explicit clause allowing this (Article 6:92(2) DCC).
7. The possibility of judicial moderation is mentioned in the letter itself, which weakens the creditor’s negotiating position.
8. A notice of default is sent where a fatal deadline already suffices; this is unnecessary and legally unwise.
