Debt collection in the Netherlands runs in two stages. The amicable stage is everything a creditor does outside court: reminders, a formal notice of default, statutory interest and, for consumers, a compulsory fourteen-day letter before any collection costs may be charged. The judicial stage begins with a writ of summons served by a bailiff and ends, if the claim succeeds, in a judgment that the bailiff can enforce against wages, bank accounts and assets. Neither stage is optional in practice: skipping steps in the first stage will cost you money in the second.
When an unpaid invoice becomes a claim you can enforce
An overdue invoice is not automatically an enforceable claim. Dutch law requires that the debtor is in default (verzuim) before interest and collection costs start to run. Default usually arises after a written notice of default (ingebrekestelling) under article 6:82 of the Dutch Civil Code, which gives the debtor a reasonable final period to perform. In a number of situations, listed in article 6:83 of the Civil Code, default arises without any notice at all: where the parties agreed a fixed payment date that has passed, where the obligation arises from a wrongful act, or where the debtor makes clear that it will not pay.
Once the debtor is in default, statutory interest runs by operation of law. For consumer transactions the rate is the ordinary statutory interest of article 6:119 of the Civil Code. For commercial transactions between businesses, or between a business and a public authority, the higher statutory commercial interest of article 6:119a applies. Both rates are fixed by order in council and change periodically, so the applicable percentage should be taken from the government's published figures for each period rather than copied from an old invoice.
Payment terms matter here too. Where the parties have agreed nothing, payment is due within thirty days of receipt of the invoice. Between businesses a longer term may be agreed, but not an unlimited one, and a large company may not impose a payment term on a small or medium-sized supplier that exceeds thirty days. A clause that goes beyond what the law allows is void, and the statutory term applies in its place, with commercial interest running from the day it expires.
The fourteen-day letter, and why it is so often wrong
Against a consumer, extrajudicial collection costs may only be charged after the creditor has sent a specific written notice under article 6:96 of the Civil Code. That letter must give the consumer at least fourteen days to pay the principal sum free of any collection costs, and it must state what the costs will be if payment is not made. The Supreme Court has held that the period runs from the day after the letter reaches the consumer, so a letter that gives the consumer fourteen days from the date of the letter itself is defective.
The consequence of a defective letter is not a warning: the claim for collection costs simply fails, and a court will strike it out even if the debtor does not raise the point. The amount of the costs themselves is fixed by decree on a sliding scale of percentages of the principal, decreasing as the claim grows, with a statutory minimum and a statutory maximum. For business debtors the parties may agree different terms in their general conditions, which is one of the few genuinely useful clauses in a set of standard terms.
The amicable phase and the rules a collection agency must follow
Most claims are still resolved before anyone goes to court, and the amicable phase is where the commercial outcome is decided. It starts with a reminder, moves to a formal demand (aanmaning) and, where the debtor responds, usually ends in a payment arrangement or a settlement for part of the claim. A creditor who is willing to accept instalments recovers more, on average, than a creditor who insists on the full amount and receives nothing.
What has changed is that this phase is now regulated. Under the Debt Collection Services Quality Act (Wet kwaliteit incassodienstverlening) collection service providers must be entered in the register of debt collection services kept by Justis, and registration has been compulsory since 1 April 2025. Registered providers must meet requirements on professional competence, the accuracy of the information in their letters, the handling of complaints and the way they contact debtors. Operating without registration is prohibited, and supervision is exercised by the Justice and Security Inspectorate, which can impose fines and remove a provider from the register.
Two practical consequences follow. If you are a creditor, using an unregistered agency exposes your own claim to argument and your business to reputational risk, so the register is worth checking before you instruct anyone. If you are a debtor, a letter demanding sums that are not supported by the law, or that threatens measures the sender has no power to take, is not merely unpleasant; it is a breach of the rules and a ground for complaint.
It is also worth being clear about who has which powers. A collection agency (incassobureau) has none beyond those of any other creditor: it can write, telephone and negotiate, and it cannot seize anything. A bailiff (gerechtsdeurwaarder) is a public official appointed by royal decree, and only a bailiff may serve a writ of summons and levy attachment. A bailiff acting in the amicable phase, before any judgment, is acting as an ordinary agent and has no more coercive power than the agency does. The letterhead does not change that.
Time limits: when a claim expires and how to stop the clock
A claim that has not been pursued eventually becomes unenforceable, and creditors lose more money to limitation periods than to insolvent debtors. The general period for a contractual claim to payment is five years under article 3:307 of the Civil Code, running from the day after the claim became due and payable. Shorter periods apply in specific cases: a consumer buyer's claim under a contract of sale is subject to a two-year period, and claims arising from a wrongful act are subject to their own regime.
The period can be interrupted. Under article 3:317 of the Civil Code a written demand or a written notice in which the creditor unequivocally reserves its right to performance interrupts limitation, and a fresh period starts the next day. Issuing proceedings interrupts it as well. What does not interrupt it is an internal file note, a telephone call that is not confirmed in writing, or a reminder that does not make clear that the creditor still claims payment. Keeping a dated copy of every demand is the cheapest form of litigation insurance available.
Before any of this matters, the claim has to exist and be provable. The file should show what was agreed, that the goods or services were delivered, that the invoice was sent and received, and which general conditions apply and when they were made available. Where a claim is disputed on the merits rather than on capacity to pay, it is usually the delivery and the terms that decide it, and our explanation of what a claim is under Dutch law sets out the elements in more detail.
Securing the claim before judgment
Proceedings take time, and a debtor who knows a claim is coming can move assets in the meantime. Dutch law offers an unusually accessible remedy for this: prejudgment attachment (conservatoir beslag). On a written application, the interim relief judge of the district court can give leave to attach bank accounts, receivables owed to the debtor by third parties, movable goods, shares or immovable property, before the substantive claim has been decided.
The application is normally dealt with without hearing the debtor, often within days, and the attachment therefore lands as a surprise. Leave is given on a summary assessment of the claim, and the judge sets a period, commonly fourteen days, within which the main proceedings must be commenced. If they are not, the attachment lapses.
The remedy has a sharp edge. A creditor who levies attachment and then loses the case is in principle liable for the damage caused, without the debtor having to prove fault, because the risk of an unfounded attachment lies with the party that chose to impose it. That makes prejudgment attachment a serious step rather than a negotiating gesture, and it is worth reading our article on prejudgment attachment in Dutch law before deciding to use it.
Court proceedings: which court and what happens
Which court hears the claim depends on its value and its subject matter. The subdistrict court (kantonrechter) deals with money claims up to the statutory limit, currently 25,000 euro, and regardless of value with cases about employment, tenancy, consumer credit and consumer sales. Everything else goes to the district court in the ordinary chamber.
The distinction has a direct effect on cost. Before the subdistrict court, parties may conduct their own case: legal representation is not compulsory, and a company may be represented by its own director or by an authorised agent. Before the district court, representation by a lawyer is mandatory. The frequently repeated statement that a writ of summons must always be drafted by a lawyer is wrong, and it discourages small creditors from pursuing perfectly good claims.
The proceedings begin with a writ of summons (dagvaarding) setting out the claim, the grounds and the evidence, which a bailiff serves on the debtor. If the debtor does not appear, the court gives judgment in default, and it will grant the claim unless it appears unlawful or unfounded, which is why a defective fourteen-day letter still costs the creditor its collection costs even when nobody turns up. If the debtor does appear and defends, there is usually an exchange of written statements followed by an oral hearing, and the court then gives judgment (vonnis).
Three points about cost and risk. Court fees are payable in advance by both parties, are set on a scale according to the value of the claim and the status of the party, and are indexed each year, so the current amounts should be taken from the judiciary's published table. The losing party is normally ordered to pay the winner's costs, but the lawyer's fees in that order are calculated on a fixed internal scale and rarely cover what was actually spent. And a judgment for a small sum may not be open to appeal at all, because the Code of Civil Procedure sets a minimum value below which appeal is excluded.
A judgment is normally declared provisionally enforceable, which means it can be enforced immediately even if an appeal is lodged. If the judgment is later overturned, the creditor must undo what it has collected, and it bears the risk of the debtor's insolvency in the meantime.
Enforcement: what a bailiff may and may not do
A judgment becomes enforceable once the bailiff has served the official copy on the debtor. Service is not a formality; it is the moment from which the debtor is on notice and from which short statutory periods begin to run. The bailiff will normally serve the judgment together with a demand for payment, and only after that demand has expired may attachment follow.
From there the bailiff has a defined toolkit. Attachment under a third party (derdenbeslag) catches money that someone else owes the debtor, most commonly wages held by an employer, a benefit paid by a public body or a credit balance at a bank; the third party must declare what it holds and pay it to the bailiff. Attachment of movable goods allows business inventory, machinery or a vehicle to be seized and sold at public auction. Immovable property can be attached and sold through a notary. Shares in a company can be attached as well, which in a family business is often more effective than seizing anything physical.
Against those powers Dutch law sets real limits. A protected earnings threshold, the beslagvrije voet, guarantees the debtor a minimum income that cannot be attached. Since the simplification of that regime the bailiff calculates the threshold itself from data held in the national income and benefits records, rather than depending on information the debtor supplies, which removed a longstanding source of hardship. Goods that are necessary for daily life, such as beds, clothing, food and the tools a debtor needs to earn a living, cannot be seized at all. There is no imprisonment for inability to pay a money debt; coercive detention exists in Dutch law only in narrow circumstances and not as a general collection measure.
Where the debtor has several creditors, the bailiffs coordinate through a central attachment register, and a coordinating bailiff distributes what is collected. A creditor who arrives late in a queue on a modest salary may recover nothing for years, which is a reason to assess recoverability before starting proceedings rather than after winning them. A debtor who believes enforcement is being conducted unlawfully is not without remedy either, as our article on legal remedies against enforcement of a judgment explains.
Cross-border collection within the EU
For creditors based outside the Netherlands, and for Dutch creditors with foreign debtors, European instruments often work better than a purely national route. A judgment given in one member state is recognised and enforced in the others under the Brussels I bis Regulation without any intermediate declaration of enforceability, so a Dutch judgment can be handed straight to a bailiff elsewhere in the Union, and a foreign judgment to a Dutch one.
Two simplified procedures exist for the claim itself. The European order for payment is a written procedure for uncontested cross-border money claims, in which the court issues an order on the basis of a standard form; if the debtor objects, the case continues as ordinary proceedings. The European small claims procedure handles low-value cross-border claims largely in writing and without compulsory legal representation. Alongside these, the European account preservation order allows a creditor to freeze a debtor's bank account in another member state, on conditions comparable to Dutch prejudgment attachment.
Which route is best depends on where the debtor and its assets are, what the contract says about jurisdiction and applicable law, and whether the claim is genuinely undisputed. Those questions should be answered before the first letter is sent, because a jurisdiction clause that nobody read is discovered at the worst possible moment.
When there is nothing left to collect
Not every claim is worth enforcing, and recognising that early saves more than any procedural refinement. If a corporate debtor has ceased to pay and there is more than one creditor, a creditor can petition for its bankruptcy under the Bankruptcy Act. The petition is sometimes used as pressure, and it does concentrate minds, but it is a blunt instrument: once bankruptcy is declared the trustee takes over, individual enforcement stops, and an unsecured creditor usually receives little or nothing. Our overview of the Bankruptcy Act and its procedures sets out how the estate is administered.
A business in difficulty may also propose a restructuring plan outside bankruptcy, which the court can confirm so that it binds dissenting creditors, including those who voted against it. That route has changed the calculation for creditors of larger debtors considerably, and it is explained in our article on the WHOA restructuring scheme. For an individual debtor, the statutory debt rescheduling scheme and the municipal debt assistance route both end in a moratorium on enforcement, so a creditor who ignores an approaching arrangement can find its attachment overtaken.
The practical test before starting proceedings is simple: is there anything to recover from, and can the file prove the claim. A search of the trade register, the land registry and, where relevant, the register of attachments answers the first question in an afternoon. Suing a debtor with no assets produces a judgment, a bill and no money.
What a creditor should do now
Debt collection in the Netherlands rewards preparation more than aggression. Agree a payment term and applicable general conditions in writing before you deliver, and make sure the conditions are actually handed over, because terms that were never provided can be annulled. Invoice promptly and keep the proof of dispatch. Send the reminder on the day the term expires rather than a month later, and against a consumer send a fourteen-day letter that complies with the statute, because that single document decides whether your collection costs survive.
If payment still does not follow, decide deliberately rather than by default: assess recoverability, check the limitation period, consider whether an attachment is proportionate, and choose between the subdistrict court, the district court and a European procedure. And keep the file. Almost every claim that fails in a Dutch court fails on evidence or on a missed formality, not on the merits.
Common questions about debt collection in the Netherlands
How long does the debt collection process take?
There’s no single, straightforward answer to this, as the timeline can vary wildly depending on the situation. The initial, or amicable, phase can wrap up in just a few weeks if the debtor is cooperative and quick to respond. But if communication drags on or it takes multiple reminders to get a response, this stage could easily stretch out for several months.
If the matter has to go to court, you’re looking at a much longer timeframe. A simple, undisputed court case might add several more months to the clock. For more complex situations—perhaps with major disagreements or multiple parties involved—the entire journey from the first demand letter to a final court judgment could take well over a year. You also have to factor in the court’s own schedule, as their current caseload can create further delays.
Who pays for the debt collection costs?
In the Netherlands, the law is clear: the debtor is generally responsible for paying the extra costs associated with collection. This holds true as long as the creditor has played by the rules and followed all the correct legal steps, like sending the required notices.
However, there are crucial protections in place for consumers. The Wet Incassokosten (WIK), or the Debt Collection Costs Act, puts a cap on the fees that can be charged for consumer debts. These costs are calculated as a specific percentage of the original debt, which stops creditors from piling on excessive or unfair fees. It creates a system that’s predictable and fair for everyone involved.
Can I dispute a debt during the collection process?
Absolutely. You have a legal right to dispute a debt at any point. It’s always best to put your dispute in writing as early as you can, clearly outlining why you disagree with the claim. You might be disputing the amount, or you might believe the debt isn’t valid at all.
Once you’ve officially disputed the debt with a solid reason, the collection agency can’t keep pursuing you aggressively until the disagreement is sorted out. If the creditor decides to take you to court, your written dispute will become the foundation of your legal defence.
The ability to dispute a debt is a fundamental right that ensures fairness. It forces the creditor to prove their claim and prevents collection action on potentially incorrect or fraudulent invoices.
What is the difference between a debt collection agency and a bailiff?
This is a really important distinction in the Dutch system, and it’s one that causes a lot of confusion.
- A debt collection agency (incassobureau) operates only in the amicable phase. They can send letters, make phone calls, and try to negotiate a payment plan. However, they have no special legal powers to force you to pay.
- A bailiff (deurwaarder), on the other hand, is a public official appointed by the Crown. They are the only ones legally allowed to kick off the judicial process by serving a court summons. If a court issues a judgment, it’s the bailiff who can enforce it by seizing assets or garnishing wages. While a bailiff can also manage amicable collections, their real authority kicks in when things get legal.
Beyond the collection process itself, it’s worth remembering how this can affect your wider financial life. Late payments and defaults can take a toll on your credit standing, which might make it harder to get a loan in the future.
