Preliminary purchase agreement in the Netherlands: what it binds you to

A preliminary purchase agreement in the Netherlands is not preliminary at all. The Dutch name for it, voorlopige koopovereenkomst, is a historical misnomer: once buyer and seller have both signed, a binding contract exists and neither party can simply walk away. A consumer buying a home has three days to dissolve the purchase without giving reasons; after that, the only routes out are an agreed condition such as a financing proviso, the other party consenting, or a legal ground for dissolution.

What a voorlopige koopovereenkomst really is

The agreement is called provisional because it precedes the notarial deed of transfer. That is the only sense in which it is provisional. Under Dutch law ownership of immovable property passes only through a deed executed by a civil-law notary (notaris) and registered in the Kadaster, so between signature and completion there is a period, usually of one to three months, in which the parties are bound to each other but the property has not yet changed hands. The purchase agreement governs that period.

Both obligations in it are real. The seller must deliver the property in the agreed condition and free of the encumbrances that were not disclosed; the buyer must pay the price and appear at the notary on the agreed date. Failure to do so is a breach of contract, and the model agreements used across the Dutch market attach a penalty to it. Anyone who signs believing that the document merely records an intention has misunderstood what they have done.

What the agreement has to contain

A contract of sale exists once the parties agree on the object and the price. Everything else can in principle be filled in by the law, but a workable Dutch purchase agreement records considerably more: the full names and addresses of the parties, an exact description of the property with its cadastral designation, the price, the date of transfer, which movable goods are included, and the state in which the property is delivered.

Beyond that come the clauses that decide who carries which risk. Which conditions must be met, and by when. Whether the buyer pays a deposit or provides a bank guarantee. What the seller has declared about the property, and what the buyer accepts as a known defect. Whether the seller has disclosed matters such as soil contamination, an underground fuel tank, asbestos, monument status or an active dispute with a neighbour. Most disputes after completion turn out to be disputes about a sentence that was never written down.

Written form and the three-day cooling-off period

Article 7:2 of the Dutch Civil Code (Burgerlijk Wetboek) applies where a dwelling is bought by a natural person who is not acting in the course of a profession or business. Two rules follow from it. The purchase must be concluded in writing, so an oral agreement on the price does not yet bind the private buyer of a home. And the buyer has a cooling-off period (bedenktijd) of three days, running from the day after the buyer receives a copy of the signed agreement, in which the purchase may be dissolved without giving any reason and without owing anything.

Three details decide cases. The period must include at least two days that are not a Saturday, a Sunday or a public holiday, so a Friday delivery does not cost the buyer the weekend. The period runs from receipt of the signed document, which is why the moment of handover should be recorded. And the right belongs to the buyer alone: a seller who regrets the deal has no cooling-off period, and neither does a buyer who is a company or who is buying in the course of a business. The protection cannot be contracted away to the buyer disadvantage.

The cooling-off period is short and it is absolute. Use it to have the agreement checked, not to negotiate. If the same parties conclude a new purchase of the same property within six months, the buyer does not get a fresh three days.

Conditions: how a voorbehoud actually works

A condition, or voorbehoud, is the buyer main escape route after the cooling-off period has expired. The best known is the financing proviso (financieringsvoorbehoud), which entitles the buyer to dissolve the purchase if no mortgage offer is obtained. It is not automatic. It exists only if it was written into the agreement, it lasts only until the date stated there, and it can normally be invoked only by a written notice served in time and supported by documentation of the refusals.

That last requirement catches people out. A buyer who lets the date pass, or who sends an unsupported email, loses the proviso and remains bound to a purchase they cannot finance, which is precisely the situation the penalty clause is designed for. If a mortgage adviser needs more time, ask the seller in writing for an extension and get the extension in writing as well. Other conditions are common too: a satisfactory structural survey, the sale of the buyer own home, the grant of a permit, or a positive outcome from the municipality on the intended use.

Deposit, bank guarantee and the penalty clause

The model agreements used by the Dutch estate agents associations require the buyer to pay a deposit into the notary client account, or to provide a bank guarantee for the same amount, usually ten per cent of the purchase price, within a set number of weeks after the cooling-off period ends. The same models set the penalty for failing to perform at ten per cent of the price, payable on top of the obligation to perform or as compensation if the seller dissolves.

The penalty is not payable automatically. As a rule the defaulting party must first be given written notice to perform within a stated period, and only after that period passes without performance is the party in default. The injured party then chooses: demand performance, or dissolve and claim the penalty. A court may reduce a contractual penalty, but only where fairness manifestly requires it, which is a demanding test; assuming that a judge will simply scale the figure down is a poor plan.

Vormerkung: registering the purchase to protect your position

Between signature and transfer the buyer is exposed. The seller could sell the same house to someone else, grant a mortgage over it, or be declared bankrupt, and a purchase agreement on its own gives the buyer only a personal claim. Article 7:3 of the Civil Code allows the purchase of immovable property to be registered in the public registers. This registration, known by its German name Vormerkung, makes the buyer immune to a later sale, a later mortgage, an attachment or an insolvency on the seller side.

Registration is done by the notary and costs little. Its effect lapses retroactively if the property has not been transferred within six months, and a new registration between the same parties is then blocked for another six months, so it is a shield for a normal completion period rather than an open-ended reservation. During the three-day cooling-off period, registration requires a notarial deed. For any purchase with a long gap before completion, or where the seller finances are uncertain, it should be the default.

Breaking off negotiations before anything is signed

There is a stage before the agreement in which nothing has been signed, and Dutch law does not leave it entirely free. The starting point is that each party may break off negotiations. That freedom ends where the other party could justifiably rely on a contract coming about, or where breaking off would for other reasons be unacceptable; in those circumstances the party who walks away can be liable for costs and, exceptionally, for the loss of the bargain. The Supreme Court set out that test in its judgment of 12 August 2005 in CBB v JPO (ECLI:NL:HR:2005:AT7337), and it applies it strictly: liability for broken-off negotiations is the exception, not the rule.

Letters of intent in business acquisitions

In the sale of a business or of shares, the document that precedes the deal is a letter of intent (intentieverklaring). Here the label matters less than the wording. Most letters of intent leave the commercial terms non-binding while making a handful of clauses fully binding: confidentiality, exclusivity for a stated period, who pays the costs of due diligence, the governing law and the forum. If the intention is that no deal exists until a share purchase agreement is signed, say so in a single unambiguous sentence, because a letter that reads like a completed bargain will be treated as one.

Disclosure, investigation and the clauses that shift the risk

Dutch law divides responsibility for defects between a seller duty to disclose and a buyer duty to investigate. The seller must tell the buyer what they know about defects that stand in the way of normal use, even if the buyer does not ask; a seller who stays silent about a leaking roof or a structural problem cannot later hide behind the buyer failure to look. The buyer, for their part, must make the enquiries a reasonably careful purchaser would make, which for an older property usually means a structural survey.

Where the two duties meet, the seller duty generally prevails: silence about a known defect is not cured by the buyer not having investigated. That is why the standard agreements contain a set of clauses designed to move the line. An age clause (ouderdomsclausule) records that the property is old and that the buyer accepts a lower standard of construction. A non-occupancy clause (niet-zelfbewoningsclausule) is used by heirs and investors who have never lived in the property and therefore cannot say much about it. A clause in which the buyer accepts a named defect removes that defect from the discussion entirely.

None of these clauses is harmless boilerplate. Each one narrows what the buyer can claim later, and each one is negotiable. If a seller adds one late in the process, treat it as a signal to ask what they know, and record the answer in the agreement rather than in an email.

What to check before you sign

Read the description of what you are buying against the cadastral extract and the plans, not against the sales brochure. Check that every condition you rely on is in the document, with a date and a procedure for invoking it. Check the completion date against the date your mortgage offer expires and, if you are selling as well, against the completion date of your own sale. Check what the seller has declared and what you have accepted, because a clause in which you accept the property as it stands narrows your remedies afterwards considerably.

Two points deserve separate attention. Complaints about defects must be made within a reasonable time after discovery; the fixed two-month rule that applies to consumer purchases of movable goods does not apply to the purchase of a house, but delay still costs the buyer their claim. And transfer tax, mortgage interest relief and any tax consequences of the structure you choose are matters for a tax adviser, not for your lawyer or your estate agent.
