Letter of intent in the Netherlands: when is it binding?

A letter of intent records what you and the other party have agreed so far and how you intend to proceed. Whether it binds you depends on its content, not its title: a document called a letter of intent can contain enforceable obligations, and walking away from advanced negotiations can itself make you liable under Dutch law.

A letter of intent (LOI, sometimes called a memorandum of understanding or heads of terms) is common in company acquisitions, property transactions and joint ventures. Below we explain when it binds you, which clauses belong in it, how the Dutch courts deal with broken-off negotiations and how you avoid the most common drafting mistakes.

What is a letter of intent?

It is a written record of the main terms of a deal that is still being negotiated. It sets out the direction of travel before the final agreement is drafted.

In a negotiation, much is discussed orally. A letter of intent puts the key points on paper: what is being sold or agreed, the proposed price or the way it will be calculated, the steps still to be taken and the timetable. That reduces misunderstandings later on. It also shows that both sides are serious, which gives each of them the confidence to invest time and money in the next phase, such as a due diligence investigation.

A letter of intent is useful for several reasons:

• it records key terms such as price, payment structure and timetable;
• it shows commitment, so that both sides dedicate resources to the deal;
• it sets the framework for due diligence;
• it can grant exclusivity, so that the seller does not negotiate with others for a fixed period.

The table below gives a brief overview.

Is a letter of intent binding under Dutch law?

Partly, and that depends on what the document says and how the parties behaved. The title “letter of intent” does not make a document non-binding.

Under Dutch law, an agreement comes about through offer and acceptance (Article 6:217 of the Dutch Civil Code, BW). What counts is not only the words used, but what each party could reasonably infer from the other’s statements and conduct (Articles 3:33 and 3:35 BW). A letter of intent that records all essential terms and is signed without reservation can therefore amount to a binding agreement, even if the parties intended to sign a “final” contract later.

How a document is interpreted is determined by the Haviltex test, named after the Supreme Court (Hoge Raad) judgment of 13 March 1981 (ECLI:NL:HR:1981:AG4158). The court looks at the meaning the parties could reasonably attribute to the provisions in the circumstances and at what they could reasonably expect from each other. The wording is important, but the circumstances, the parties’ expertise and whether they had legal advice also count.

In practice, a letter of intent usually contains two kinds of provisions. The commercial terms, such as an indicative price or a proposed structure, are meant to be non-binding. Other clauses, such as exclusivity and confidentiality, are meant to bind the parties immediately. If you do not say clearly which is which, you leave the question to a court.

Why reasonableness and fairness matter

Dutch law does not treat the negotiation phase as a free-for-all. Parties who negotiate are in a special legal relationship governed by reasonableness and fairness (redelijkheid en billijkheid).

That principle, which also applies to contracts under Article 6:248 BW, requires each party to take the other’s legitimate interests into account. Signing a letter of intent is a clear signal that negotiations have become serious. The further the talks progress, the more the other party may rely on a deal coming about, and the more careful you must be about walking away.

When can you break off negotiations?

In principle you are free to walk away. Breaking off becomes unlawful only if it is unacceptable in view of the other party’s justified reliance on a contract, or in view of other circumstances.

The Supreme Court set out this test in its CBB/JPO judgment of 12 August 2005 (ECLI:NL:HR:2005:AT7337). The court looks at the whole course of the negotiations. Relevant factors include the extent to which the party walking away created the other party’s expectations, that party’s own legitimate interests and any unforeseen changes in circumstances during the talks.

The Supreme Court stressed that courts must apply this test with restraint. Freedom to negotiate is the starting point. A party that breaks off after a signed letter of intent is not automatically liable. But where the letter records agreement on the main points and the other side has invested heavily on that basis, the risk increases.

If breaking off is found to be unacceptable, the party walking away may have to compensate the other party’s costs, such as advisers’ fees and the costs of due diligence. In exceptional cases, where the negotiations had progressed so far that a contract would almost certainly have come about, a court can also award compensation for lost profit. A court can also order the parties to continue negotiating.

A well-drafted letter of intent helps you control this risk. You can agree in advance that each party bears its own costs, that either party may end the negotiations without giving reasons and that no claim for lost profit can be made. Such clauses carry weight when a court assesses whether breaking off was acceptable, although they do not exclude every possible claim.

Which clauses are binding and which are not?

You decide that in the document itself. State expressly which provisions bind the parties immediately and which only express intentions.

Getting this distinction right is the core of a safe letter of intent. The following terms are usually non-binding:

• Indicative price. A starting point that is expected to change after due diligence.
• Transaction structure. The final structure may shift after tax or legal advice.
• Conditions precedent. The steps that must be completed before the deal can be finalised, such as financing or approvals.

Other clauses are meant to bind the parties as soon as they sign. They do not concern the final deal, but how the parties behave while working towards it:

• Exclusivity. The seller undertakes not to negotiate with other buyers for a fixed period. A breach can lead to a claim for damages.
• Confidentiality. Information exchanged stays confidential, even if the deal collapses.
• Governing law and jurisdiction. Dutch law applies and a named court or arbitration body deals with disputes.
• Termination and costs. How the letter ends and who pays which costs.

If you state explicitly that only these clauses are binding, you create a clear boundary. You can explore the deal freely, while the negotiation process itself remains protected. If you are looking at financing arrangements or security for the deal, include those questions in the conditions, so that the conditions remain workable in practice.

What should a letter of intent contain?

At a minimum: the parties, the subject of the transaction, the financial terms, the conditions, a timetable and the binding clauses. Vague wording in any of these creates room for disputes.

The parties and the scope of the deal

State the full legal names and addresses of every party: the buyer, the seller and, where relevant, parent companies. Avoid vague terms such as “our group”. Include the Chamber of Commerce (KvK) number of each Dutch company, so that there is no doubt about who is bound.

Then describe what the deal is about. Are you buying shares, specific assets, a building or a business as a whole? In a business acquisition, specify whether the deal includes intellectual property, contracts and employees, and which liabilities stay behind. In an asset deal, employees can transfer automatically under the rules on transfer of an undertaking, which you need to take into account from the start.

The financial terms

The price is usually stated as indicative. The mechanics behind it should still be described in detail:

• the proposed price, or the formula used to calculate it, for instance a multiple of earnings;
• the method of payment: cash, shares or a combination;
• the timing: a single payment at completion or payments spread over time;
• any earn-out or escrow, where part of the price depends on future results or is held back.

Setting out these mechanics is not about fixing the price. It confirms that both sides share the same understanding of how the deal is valued before they spend more time and money.

Conditions and timetable

Most deals depend on conditions precedent: steps that must be completed before the transaction becomes final. Typical examples are a satisfactory due diligence investigation, financing for the buyer, approval by the Netherlands Authority for Consumers and Markets (ACM) or another regulator, and approval by shareholders or a supervisory board. Where a Dutch company has a works council (ondernemingsraad), its advice may also be required before a decision is taken.

Link these conditions to a realistic timetable, with target dates for completing due diligence, drafting the final agreement and closing. Define what “satisfactory” due diligence means, so that it cannot be used as a free exit.

The binding clauses

Close with the provisions that govern the negotiation itself: exclusivity for a fixed period, confidentiality, governing law and a costs arrangement. Mark these expressly as binding and state that the rest of the letter is not. Add an end date on which the letter lapses if no final agreement has been signed.

How is a letter of intent used in practice?

The form depends on the deal. In acquisitions it is the roadmap to the share or asset purchase agreement; in property and employment matters it plays a more limited role.

Mergers and acquisitions

In a company acquisition a letter of intent is almost standard. It records the proposed price and how it will be paid, what exactly is being bought and the main conditions. That alignment matters before both sides spend considerable time and money on due diligence.

The binding clauses are just as important here. An exclusivity period stops the seller from approaching other buyers and gives the buyer the confidence to invest in a thorough investigation. Confidentiality protects the financial and operational information that is exchanged. Our article on mergers and acquisitions in the Netherlands explains the rest of the process, from due diligence to closing.

Property transactions

In commercial property deals a letter of intent is often used to agree the main terms before expensive technical and legal checks start. It typically covers:

• a clear description of the property;
• the proposed purchase price;
• a due diligence period for technical, environmental and legal inspections;
• a financing condition;
• a target date for transfer of ownership at the civil-law notary.

For residential property bought by a consumer, Dutch law adds a specific rule. Under Article 7:2 BW, the purchase of a home by a private buyer must be entered into in writing, and the buyer then has a three-day cooling-off period. An informal letter of intent does not replace that written purchase agreement.

Employment

Employers sometimes use a letter of intent to confirm an offer before the employment contract is signed, for instance while a work or residence permit is being arranged. Be careful: if the letter records the essential terms, such as position, salary and start date, and is accepted, it may already be an employment contract. If you do not intend that, make any conditions, such as obtaining a permit, explicit.

Which mistakes should you avoid?

The most common mistakes are vague wording, failing to state what is binding and open-ended exclusivity. Each can turn a useful document into a source of disputes.

Ambiguous language is the first trap. If the price is described loosely, the other side may argue that a firm offer was made rather than a starting point. Use precise wording and state expressly that figures are indicative.

The second trap is not stating which parts are binding. Under the Haviltex test a court then decides what the parties could reasonably expect, and the answer may differ from what you had in mind. Combined with reasonableness and fairness, an unclear letter can create obligations you did not intend.

Failing to set clear boundaries

An exclusivity clause that is too long or unclear can lock you out of better opportunities. Specify its exact duration and scope, and what happens when it ends.

Equally, a letter of intent without an end date can leave the parties in uncertainty. A fixed long-stop date means that negotiations either progress or end formally. Three precautions help:

• label each section as binding or non-binding;
• define key terms, such as what counts as satisfactory due diligence;
• set specific dates, including the date on which the letter lapses.

Finally, do not underestimate the risk of walking away. After a signed letter of intent, breaking off without a good reason can, in the circumstances described above, make you liable for the other party’s costs. Take an entrepreneur who signs a detailed letter of intent, lets the buyer complete due diligence and then sells to a third party during the exclusivity period: that seller runs a real risk of a claim.

How does a letter of intent differ from other preliminary documents?

The labels vary, but the legal test is the same. A term sheet, a memorandum of understanding and heads of terms are all judged by their content and by what the parties could reasonably expect.

A term sheet is usually a short list of commercial terms, often without the explanatory text of a letter. A memorandum of understanding is common in cooperation projects and joint ventures. A non-disclosure agreement (NDA) is a separate, fully binding contract that covers only confidentiality; it is often signed before the letter of intent, at the moment the first information is exchanged.

A preliminary purchase agreement or an option is something else again. Such documents are intended to bind: they oblige a party to sell or give the other party the right to buy on agreed terms. If you sign a document that commits you to the final deal, you are no longer in the phase of a letter of intent. Check the title, but above all check the words.

Who may sign on behalf of a company?

Only a person authorised to represent the company. For a Dutch private limited company (BV) that is, in principle, the board of directors, unless the articles of association provide otherwise (Article 2:240 BW).

Before you sign, check the extract from the trade register of the Chamber of Commerce. It shows who is a director and whether a director may act alone or only jointly with another director. Someone may also act under a power of attorney; ask for a copy. If the signatory was not authorised, the company may not be bound, and you may end up arguing about that instead of about the deal.

Internal approvals are a separate matter. The articles of association or a shareholders’ agreement may require the approval of the general meeting or the supervisory board for certain decisions. Such internal rules do not always affect the validity of a signature towards the other party, but they can create liability for the directors internally. Make any required approval a condition in the letter.

What happens after the letter of intent?

The letter is followed by due diligence, negotiation of the final agreement, signing and completion. The letter should say how long each step may take.

During due diligence the buyer investigates the legal, financial, tax and operational position of the target. The findings often lead to adjustments of the price or to specific guarantees and indemnities in the final agreement. That is why the price in the letter of intent is usually indicative.

The final agreement, such as a share purchase agreement, contains the definitive terms, the warranties and the arrangements for completion. In a share deal involving a Dutch BV, the shares are transferred by a notarial deed executed before a civil-law notary in the Netherlands (Article 2:196 BW). In an asset deal, each asset transfers in the way the law prescribes for it, for instance a notarial deed for real estate.

Once the final agreement is signed, it replaces the letter of intent. Include an “entire agreement” clause stating that earlier documents no longer apply, with the possible exception of the confidentiality arrangement if it is not repeated in the final agreement.

What if a dispute arises?

First look at what the letter itself says about governing law, jurisdiction and costs. Then assess whether a binding clause was breached or whether negotiations were broken off unacceptably.

Many disputes are resolved by negotiation or mediation, because the parties often still have a commercial interest in each other. If that fails, the case goes to the court or arbitration body named in the letter. In urgent cases, for instance where confidential information threatens to be misused, you can ask the preliminary relief judge (voorzieningenrechter) for an order in summary proceedings (kort geding). Our page on business dispute resolution in the Netherlands sets out the options.

What should you check before you sign?

Read the letter as if a judge will read it later. Ask yourself what the other party could reasonably conclude from it, and whether that matches what you intend.

Before signing, go through these points. Does the letter say expressly which clauses are binding and that the rest is not? Is the price clearly indicative, and is the method of calculation described? Are the conditions specific enough, and is it clear who decides whether they are met? Does the exclusivity have a fixed end date? Is there a date on which the letter lapses? Is there a costs arrangement, and does it exclude claims for lost profit? Are governing law and the competent court or arbitration body named? And is the signatory authorised to bind the company?

Also keep a record of the negotiations: minutes of meetings, emails and draft versions. If a dispute arises about whether a contract was formed or whether breaking off was acceptable, the course of the negotiations is exactly what a court will examine.

Finally, consider timing. A letter of intent signed too early, before the main points are clear, invites discussion. A letter signed too late, when all terms are already agreed, may itself be the final agreement. The right moment is when the commercial outline is clear and both sides are ready to invest in due diligence.

In summary

• A letter of intent records the main terms of a deal under negotiation; its content, not its title, determines whether it binds you.
• State expressly which clauses are binding, such as exclusivity, confidentiality, governing law and costs.
• Under CBB/JPO, breaking off negotiations is unlawful only if it is unacceptable given the other party’s justified reliance.
• Describe the parties, the scope, the price mechanism, the conditions and the timetable precisely.
• Include an end date and a costs arrangement to limit your risk.

Frequently asked questions

Is a letter of intent binding under Dutch law?

Often only in part. The commercial terms are usually non-binding, while clauses on confidentiality and exclusivity are binding. A letter that records all essential terms can, however, amount to a binding agreement. State clearly in the document which parts bind you.

When should you use a letter of intent instead of a full contract?

At the start of serious negotiations, when you want to agree the main points before due diligence and before drafting the final agreement. It is a common step in acquisitions and larger property transactions.

Can you back out of a deal after signing a letter of intent?

In principle, yes, as far as the non-binding parts are concerned. You must still honour the binding clauses, such as an exclusivity period. And if you break off at an advanced stage without a good reason, you may have to compensate the other party’s costs.

Do you need a lawyer to draft a letter of intent?

For a simple deal you can draft one yourself. For an acquisition or a significant property transaction, legal input helps to separate binding from non-binding terms and to limit the risk of liability for breaking off negotiations.
