A Dutch real estate purchase agreement (koopovereenkomst) is the written contract in which seller and buyer record the terms of the sale. It does not transfer ownership: that happens only when a civil-law notary (notaris) executes a deed of transfer that is registered in the public registers of the Land Registry (Kadaster), as Article 3:89 of the Dutch Civil Code (BW) requires.
If you buy a home as a private individual, Article 7:2 BW requires the agreement to be in writing and gives you three days to withdraw without giving reasons and without cost. Almost everything else that people consider standard, such as the financing condition, the survey condition, the deposit and the penalty clause, is contractual. It only protects you if it is in your agreement and drafted the way you intend. Below we go through the main clauses, the conditions and the timeline from accepted offer to transfer.
Why does the purchase agreement matter so much?
Because it fixes your rights and obligations before you own anything. Once the cooling-off period has passed, you can only get out of the purchase on the grounds that the agreement itself provides or that the law gives you.
The agreement records the price, the property, the date of transfer, the conditions and what happens if one of the parties does not perform. The notary later uses it as the basis for the deed of transfer. Whatever is missing from the agreement is difficult to add afterwards.
The written requirement
For the purchase of a home by a private buyer, a verbal agreement is not enough. Under Article 7:2(1) BW, the purchase of residential property by a buyer who is not acting in the course of a profession or business must be in writing. Until a written agreement exists, the purchase has not been concluded.
The buyer must receive a copy of the signed agreement, for example on paper or by email. That moment matters, because the cooling-off period starts on the day after the buyer receives it.
The written requirement does not apply to a buyer acting in the course of a business, such as a company buying commercial premises or an investor buying through a private limited company (BV). For such buyers, an oral agreement on the essential terms can already be binding. Before you sign, it is worth having the text checked; our article on how to sign a contract and avoid hidden legal issues explains what to look for.
Which clauses does a Dutch purchase agreement contain?
Most agreements for homes follow a model drawn up by the estate agents’ associations. They contain the parties, the property, the price, the transfer date, the conditions, the deposit or bank guarantee and the consequences of default.
The core elements are the following. The purchase price (koopsom) is the agreed price and the basis for the deposit and the transfer tax. The property is described with its address and its cadastral designation, including what is and is not included in the sale, such as fixtures and movables. The transfer date (leveringsdatum) is the day on which the deed of transfer is executed and you receive the keys.
Next come the clauses about the condition of the property. The seller states what the buyer may expect, for example that the property is suitable for normal use as a home, and lists known defects. These clauses determine to a large extent what you can do if a defect appears after the transfer.
Essential clauses in a Dutch purchase agreement
The table below summarises the clauses you will find in most agreements and what they mean for you as a buyer.
| Clause (Dutch term) | Purpose | Point of attention for buyers |
|---|---|---|
| Purchase price (koopsom) | States the agreed price, the basis for the deposit and transfer tax. | Check that it matches the accepted offer and what is included for that price. |
| Transfer date (leveringsdatum) | Sets the date of transfer at the notary and the handover of the keys. | Align it with your mortgage and the end of your current lease or sale. |
| Resolutive conditions (ontbindende voorwaarden) | Allow you to dissolve the agreement if an agreed event does not occur. | Agree realistic deadlines and invoke the condition in writing in time. |
| Deposit or bank guarantee (waarborgsom / bankgarantie) | Secures the seller if the buyer defaults; often 10 percent of the price. | Customary rather than statutory; arrange it well before the deadline. |
| Cooling-off period (bedenktijd) | Statutory three days for a private buyer to withdraw without reasons. | Starts the day after you receive the signed agreement; includes at least two working days. |
Deposit or bank guarantee
Most agreements require the buyer to pay a deposit (waarborgsom) to the notary or to provide a bank guarantee (bankgarantie), often 10 percent of the price. This is customary, not a statutory requirement, and the percentage is negotiable.
The deposit secures the seller’s claim if the buyer defaults. It is usually due a few weeks after signing, once the cooling-off period and often the financing condition have passed. Arrange it with your bank or mortgage adviser in good time.
Penalty clause
The model agreements contain a penalty for the party that fails to perform after being given notice of default. The penalty often amounts to 10 percent of the purchase price if the agreement is dissolved because of that default.
This clause is serious for buyers. A buyer who cannot pay the price on the transfer date, and who can no longer invoke a financing condition, risks forfeiting that amount. The penalty clause does not prevent the other party from claiming performance instead.
How do resolutive conditions protect you?
A resolutive condition (ontbindende voorwaarde) allows you to dissolve the agreement without penalty if a specific event occurs, or fails to occur, before an agreed date. The most common are the financing condition and the survey condition.
Resolutive conditions are contractual. They only apply if they are in the agreement, and only within the deadline stated there. A buyer who wants to invoke a condition must usually do so in writing, before the deadline, and in the manner the agreement prescribes.
The financing condition
The financing condition (financieringsvoorbehoud) allows you to dissolve the agreement if you cannot obtain a mortgage on the terms stated. The period for this is usually a few weeks after signing.
Check that the agreement states the amount of the mortgage and, if relevant, the maximum interest rate and the type of loan. The model agreements usually require you to show that you made a genuine effort, for example with written rejections from one or more lenders. What exactly you must submit follows from your agreement.
Without a financing condition, a buyer who does not obtain a mortgage remains bound. If that buyer cannot pay on the transfer date, the seller can claim the penalty or performance. The same applies if you had a condition but let the deadline pass without invoking it.
The structural survey condition
The structural survey condition (bouwkundig voorbehoud) makes the purchase conditional on the outcome of a building inspection. If the inspection reveals serious defects, you can dissolve the agreement or use the findings to renegotiate.
The clause is often linked to an amount: you may only dissolve if the estimated cost of necessary repairs exceeds a figure stated in the agreement. Agree that amount carefully, and have the inspection carried out quickly so that the report is available before the deadline.
Other conditions
Other conditions are possible, such as the sale of your current home, obtaining a permit or the absence of soil contamination. Each condition needs a clear description of the event, a deadline and the way in which it must be invoked. A vague condition leads to disputes about whether it was fulfilled.
Buying a new-build home
A new-build home is usually sold with a purchase and construction agreement (koop-/aannemingsovereenkomst) rather than an ordinary purchase agreement. The statutory written requirement and the three-day cooling-off period also apply to such a contract (Article 7:766 BW). Most developers work with standard terms and a guarantee scheme, which covers, among other things, completion of the home if the builder becomes insolvent.
Check the payment schedule, the planned completion date and what happens if it is delayed. Unlike with an existing home, you usually pay in instalments as construction progresses, and your mortgage must be arranged to match.
How does the statutory cooling-off period work?
As a private buyer of a home, you can dissolve the agreement within three days without giving reasons and without cost. This cooling-off period (bedenktijd) follows from Article 7:2(2) BW and cannot be waived in the agreement.
The period starts on the day after you receive the signed agreement or a copy of it. It lasts three calendar days, not 72 hours from the moment of signing. If the period would end on a Saturday, Sunday or public holiday, or would not include at least two working days, it is extended under the General Time Limits Act (Algemene termijnenwet) until it contains at least two working days.
An example: a buyer receives the signed agreement on a Friday. The period starts on Saturday. Three days would end on Monday, but the period must include two working days, so it runs until the end of Tuesday.
You invoke the cooling-off period by a clear statement to the seller, preferably in writing by email or registered letter to the seller or the seller’s agent. Keep proof of the time of sending. The right cannot be used twice for the same deal: if you dissolve the agreement and then buy the same property from the same seller again within six months, you do not get a new cooling-off period.
How does the process work from offer to transfer?
An accepted offer is followed by a written agreement, the cooling-off period, the deadlines of the conditions, the deposit and finally the transfer at the notary. For a private buyer, nothing is binding until the agreement has been signed.
After your offer has been accepted, the seller’s estate agent (makelaar) usually drafts the agreement. You and your own adviser receive the draft for review. This is the moment to check the price, the description of the property, the transfer date, the conditions and their deadlines, and the clauses on defects. Ask for changes before you sign, not afterwards.
After signing, you receive a copy and the cooling-off period starts. The agreement is sent to the notary, whom the buyer usually chooses because the buyer pays most of the transfer costs (kosten koper). The notary is impartial and serves the interests of both parties.
The notary can register the purchase agreement in the public registers under Article 7:3 BW. That registration protects you for six months against a later sale of the same property to someone else, against a seizure and against the seller’s bankruptcy. For a home, registration is common practice and it is worth asking for it.
Before the transfer, the notary prepares the deed of transfer (akte van levering) and the mortgage deed, and checks the registers for mortgages and attachments. On the transfer date, the deeds are signed, the purchase price is paid through the notary’s client account and the deed is registered. From that moment you are the owner.
Can the seller still back out after signing?
No. The cooling-off period only protects the buyer. Once the seller has signed, the seller is bound, even if a higher offer comes in later.
If a seller refuses to cooperate with the transfer, the buyer can give notice of default and then choose: claim performance, if necessary through the court, or dissolve the agreement and claim the contractual penalty. A buyer who wants the property itself will usually choose performance, and can ask the court to order that the judgment takes the place of the seller’s cooperation in the deed.
This is where registration of the agreement under Article 7:3 BW proves its value. If the seller sells and transfers the property to a third party after your agreement has been registered, that later transfer cannot be invoked against you. Without registration, you would in practice be left with a claim for damages.
Before a written agreement exists, the position is different. A private seller who accepts an offer orally, and then sells to someone else before anything has been signed, is in principle not bound to the first buyer. Only in exceptional circumstances can breaking off negotiations at a late stage lead to liability for costs incurred.
Which costs come on top of the purchase price?
In the Netherlands the buyer usually pays the transfer costs, which is why homes are advertised as kosten koper. These costs include transfer tax, the notary’s fees and the registration costs at the Land Registry.
Transfer tax (overdrachtsbelasting) is levied on the acquisition of real estate. A reduced rate applies to a home that you will live in yourself, and first-time buyers under a certain age can claim a one-off exemption if the value does not exceed a limit. The rates and the value limit are set by law and change regularly, so check the current figures with the Tax and Customs Administration (Belastingdienst) or the notary before you make an offer.
For 2026 the rates are 2 percent for a home that you will occupy as your main residence, 8 percent for other homes, for example a home bought to let, and 10.4 percent for non-residential property such as offices and shops. The starters’ exemption applies once, to a buyer aged 18 to 35 who will live in the home, provided the value stays below the statutory limit for that year.
Other costs usually include a valuation report for the mortgage, the fees of your mortgage adviser and your own estate agent, and the structural survey. These are costs to budget for; they are not part of the agreement with the seller, but they determine how much you can offer.
What if a defect appears after the transfer?
You may expect the property to have the characteristics needed for normal use, and the characteristics the seller promised. If it does not, it does not conform to the agreement under Article 7:17 BW, and you may be able to claim repair costs, a price reduction or damages.
Two duties are weighed against each other. The seller has a duty to disclose (mededelingsplicht) defects he knows about. The buyer has a duty to investigate (onderzoeksplicht), which is heavier if there are signs of a problem, for example in an older property. As a rule, the seller’s duty to disclose prevails over the buyer’s duty to investigate if the seller knew of a defect and kept quiet about it.
Many agreements contain clauses that limit the seller’s liability, such as an “old age clause” for older buildings or a clause for a property the seller never lived in. Such clauses are valid in principle but are interpreted in the light of all circumstances. Report a defect to the seller in writing within a reasonable time after discovering it; under Article 7:23 BW, a buyer who waits too long can lose the right to invoke the defect.
For a private buyer, a notice given within two months after discovering the defect is in any event timely (Article 7:23(1) BW). After the notice, a claim based on the defect becomes time-barred two years later (Article 7:23(2) BW). A buyer who discovers damp in the cellar, for example, should first inform the seller in writing, then have the cause and the repair costs established by an expert, and not leave the claim lying for years.
Which pitfalls should you avoid?
The most costly mistakes are waiving the survey, missing a deadline and underestimating the penalty clause. For apartments, the finances of the owners’ association are an extra point of attention.
In a competitive market, buyers sometimes offer to buy without a survey condition to make their offer more attractive. That can be a reasonable choice for a new-build property, but for an older building it shifts the risk of hidden defects entirely to you. At least consider an inspection before you make the offer.
Deadlines are the second pitfall. A buyer who does not obtain a mortgage, but forgets to invoke the financing condition before the deadline, is bound to the purchase. Put every deadline in your diary on the day you sign, and ask your lender or mortgage adviser early how long the application will take.
Buying an apartment: the owners’ association
If you buy an apartment, you become a member of the owners’ association (Vereniging van Eigenaren, VvE). The association is responsible for maintenance of the common parts, such as the roof, the facade and the lift, and you contribute to its costs.
Ask for the deed of division, the regulations, the most recent minutes, the annual accounts and the long-term maintenance plan. An association with a small reserve fund and major work ahead can impose a large extra contribution shortly after you buy. Such information also affects the price you are willing to pay.
Land on leasehold
In some cities, including Amsterdam, many homes stand on land held under a long lease (erfpacht). You then own the building, but pay a ground rent (canon) to the landowner, often the municipality. Ask for the leasehold conditions and check how long the ground rent has been fixed and when it will be revised, because a revision can raise your housing costs considerably and affects what lenders will finance.
In summary
- A private buyer’s purchase of a home must be in writing (Article 7:2 BW); ownership passes only by a notarial deed registered in the Land Registry.
- You have a three-day cooling-off period from the day after you receive the signed agreement, extended to include at least two working days.
- Financing and survey conditions are contractual: check their content and invoke them in writing before the deadline.
- Registration of the agreement under Article 7:3 BW protects you for six months against a later sale, seizure and the seller’s bankruptcy.
- Know the penalty clause, usually 10 percent of the price, and investigate the owners’ association before buying an apartment.
Frequently asked questions
Is a verbal agreement to buy a house legally binding?
Not for a private buyer of a home. Under Article 7:2 of the Dutch Civil Code the purchase must be in writing; until a written agreement has been signed, the purchase has not been concluded. For business buyers the written requirement does not apply.
What happens if I cannot get a mortgage after signing?
If your agreement contains a financing condition, you can dissolve it without penalty by invoking the condition in writing before the deadline, usually with proof of rejection by lenders. Without such a condition, or after the deadline, you remain bound and risk the contractual penalty.
Who chooses the notary for the property transfer?
In practice the buyer chooses the civil-law notary, because the buyer pays most of the transfer costs (kosten koper). The notary is impartial, prepares the deed of transfer and has it registered in the Land Registry.
The rules on the purchase of homes are in Book 7 of the Civil Code, available on wetten.overheid.nl. Law & More reviews purchase agreements for buyers and sellers and assists in disputes about defects and dissolution; see also our page on real estate law.
