Confidentiality agreements (geheimhoudingsovereenkomst) under Dutch law
A confidentiality agreement, known in Dutch as a geheimhoudingsovereenkomst or Non-Disclosure Agreement (NDA), is a contract under which one or both parties agree to keep specified information confidential and to use it only for defined purposes. In the Netherlands, NDAs are widely used to protect sensitive information shared during M&A negotiations, commercial discussions, employment relationships, and technology licensing. Under Dutch law, a properly drafted confidentiality agreement is fully enforceable and can be backed by penalty clauses and injunctive relief.
What are the key clauses in a Dutch confidentiality agreement?
A well-drafted NDA under Dutch law should cover the definition of confidential information, the scope of the confidentiality obligation, exclusions, permitted use, duration, and remedies for breach.
The definition of confidential information is the cornerstone of the agreement. A broad definition covers all information disclosed in connection with the agreed purpose, whether written, oral or electronic, and whether or not marked as confidential. A narrower definition limits protection to information that is expressly identified as confidential at the time of disclosure. In commercial practice, a broad definition is generally preferable from the disclosing party's perspective, while the receiving party will prefer clarity about what is and is not protected.
Standard exclusions from the confidentiality obligation include information already in the public domain at the time of disclosure, information already known to the recipient before disclosure, information independently developed by the recipient without use of the disclosing party's information, and information required to be disclosed by law, court order or regulatory authority. These exclusions are well established in Dutch NDA practice and Dutch courts will generally uphold them.
The permitted purpose clause restricts the use of confidential information to the specific transaction or relationship for which it is shared. A buyer in an M&A process may only use the seller's confidential information to evaluate the proposed acquisition; it may not use it to compete with the seller or to solicit the seller's customers or employees.
Is there a pre-contractual duty of confidentiality under Dutch law?
Dutch law does not impose a general statutory duty of confidentiality in the pre-contractual phase. However, the obligation to negotiate in good faith under Article 6:2 of the Dutch Civil Code may require parties to treat sensitive information shared during negotiations with appropriate discretion.
Where no written NDA is in place, a party that uses or discloses confidential information received during pre-contractual negotiations may be liable in tort under Article 6:162 of the Dutch Civil Code (onrechtmatige daad), provided the elements of unlawful conduct, fault, and damage are established. Dutch courts have recognised that deliberate misuse of confidential information disclosed in a business context constitutes unlawful conduct, even in the absence of a contractual obligation.
In practice, however, relying on tort law to protect confidential information is significantly more uncertain than having a written NDA in place. The claimant must prove actual damage and the causal link to the misuse, whereas a contractual penalty clause removes the need to prove loss. Signing a clear NDA before sharing sensitive information is therefore standard practice in any serious commercial or M&A negotiation in the Netherlands.
How are confidentiality agreements enforced under Dutch law?
Dutch law offers effective remedies for breach of a confidentiality agreement. The most important are injunctive relief through summary proceedings (kort geding) and contractual penalty clauses (boetebedingen).
The kort geding procedure before a Dutch court allows a party to obtain an injunction prohibiting ongoing or threatened disclosure of confidential information within days of filing the application. The judge in summary proceedings grants relief where the applicant can establish a sufficient degree of urgency and a prima facie case for the existence of the obligation and its breach. This makes the kort geding a powerful tool for stopping leaks quickly, far more effective than waiting for a judgment in plenary proceedings, which may take a year or more.
Penalty clauses under Article 6:91 of the Dutch Civil Code are a standard feature of Dutch NDAs. A boetebeding provides that a specified sum, typically a fixed amount per breach, plus a daily penalty for continuing breaches, is immediately due upon violation of the confidentiality obligation. The claimant need not prove the actual loss suffered. Dutch courts have the power to reduce a contractual penalty under Article 6:94 of the Dutch Civil Code if it is grossly disproportionate to the actual damage, but in practice Dutch courts exercise this power with restraint in commercial agreements between professional parties.
What is the duration of confidentiality obligations and how can they be terminated?
The duration of the confidentiality obligation should be specified in the NDA. An indefinite obligation may be appropriate for trade secrets; in other cases, a defined period of two to five years is common in Dutch commercial practice.
Dutch courts have generally upheld confidentiality obligations of indefinite duration where the protected information consists of genuine trade secrets or proprietary know-how whose commercial value does not diminish over time. For information with a finite commercial life, for example, financial projections prepared for an M&A transaction, a time-limited obligation is more appropriate and more defensible.
Many Dutch NDAs also include provisions requiring the recipient to return or destroy confidential information if negotiations break down or the permitted purpose is achieved. These provisions serve both practical and symbolic functions: they reinforce the parties' commitment to confidentiality and reduce the risk of inadvertent future use of the information.
What competition law considerations apply to Dutch NDAs?
Parties that are competitors must be careful when sharing information under an NDA. Under EU and Dutch competition law, exchanging competitively sensitive information may constitute a competition law infringement, regardless of any confidentiality obligation.
Information about pricing, capacity, strategy, customer lists or future plans is treated as competitively sensitive under EU competition law. If two competitors share such information during pre-M&A negotiations, the exchange may constitute unlawful coordination of competitive behaviour, even if the information is marked as confidential and covered by an NDA. A clean team protocol, under which only a restricted group of advisers who are ring-fenced from competitive decision-making review the sensitive information, is the standard mechanism for managing this risk in transactions involving competitors. Consulting a contract lawyer in the Netherlands with competition law experience is advisable when drafting NDAs for such transactions.
