Are NDAs legally binding in Poland? A guide for employers [2025]

Many employers hiring in Poland rely on non-disclosure agreements (or NDAs) to protect sensitive company information.

In some countries, NDAs are facing increased scrutiny and, if you’re considering hiring in Poland, you may have questions: Are NDAs enforceable in Poland and the European Union? How can you use NDAs to protect your company’s confidential information, trade secrets, and global employees? Read on to learn more.

What is an NDA?

A non-disclosure agreement (NDA) is a type of legal contract that prevents the parties involved from disclosing confidential or proprietary information to any third parties.

In Poland, the employer and employee can sign an NDA that restricts the employee from sharing specific types of information, like trade secrets, that they acquired while working for the company. Note that the Polish Civil Code establishes confidentiality during negotiations.

NDAs usually cover the obligation to use confidential information within the context of the agreement. Standard provisions may not always be comprehensive enough, requiring the inclusion of additional measures to protect trade secrets. It’s also a good idea to define procedures for handling documents and electronic media that contain confidential information after the termination of the agreement.

Are NDAs enforceable in Poland?

Yes—Under Polish law, NDAs are enforceable. However, there are a few important caveats:

• The NDA must be in writing.

• The terms must be specific as to whom the agreement applies to.

• The time period of the contract must be specified.

• The terms must be specific as to what is covered.

• The terms must specify what is not included (for example, information that has been publicly disclosed).

• The terms must also cover the disposal/protection of information after the agreement terminates.

3 things you need to know about NDAs in Poland

1. There are two versions of a Polish NDA

There is a single type of NDA in Poland, however, it may be unilateral or bilateral.

• Unilateral: In a unilateral NDA (sometimes called a non-mutual NDA), only one of the parties, typically the recipient of the confidential information, is obligated to maintain confidentiality. These agreements are common in employer-employee relationships.

• Bilateral: Bilateral NDAs (or Mutual NDAs) are binding for both parties involved in the negotiations. These agreements apply when both parties are expected to share and protect confidential information. For example, mergers, acquisitions, and similar kinds of business deals.

2. There are essential components to make NDAs enforceable

These are the things that an NDA should include to be comprehensive and enforceable:

• Clear indication of the parties involved. The NDA should clearly identify the parties involved, including their respective names and roles. This includes specifying the disclosing party, who will be sharing sensitive information, and the receiving party, who will be granted access to such information. The NDA should outline any third parties sensitive information may be shared with.

• Clear definition of confidential information. This should include the general topic of information covered by the NDA, as well as the scope of information that's covered. In Poland, the information must be stated in detail. Note that while there is no specific general definition of confidential information provided under Polish law, Poland’s Act on Combating Unfair Competition explains that information can be considered a trade secret if it meets the following criteria: it has economic value, it is technical or technological or organizational information, it is not commonly known or easily accessible to people who usually deal with this type of information. It is also important that the person authorized to have access to this information has taken measures to keep it confidential. The NDA should also define how confidential information is shared; for example, is written information considered confidential but oral information is not?

• Exclusions from confidentiality. If there are any cases when parties in the NDA are allowed to disclose confidential information (for example, after it's been made public or for an audit), those should be included in the contract or confidentiality clauses.

• Terms of the agreement. How long does the NDA last? For employment NDAs, they typically last for the duration of the employment relationship, but they can last longer with limitations.

• Information protection post-agreement: These are terms covering the disposal and protection of confidential data after the NDA ends.

• An arbitration or mediation clause for dispute resolution. These can be beneficial in the case of disputes over the NDA and maintain confidentiality obligations during the process.

• What will happen if the NDA is breached. It's a good idea to include provisions that outline any injunctions, damages, or other contractual penalties for breaching the NDA.

• Stipulate applicable law. You (or a law firm) should reference the laws used to create the NDA and have them checked. This can help in the case of arbitration or mediation.

3. There are three legal requirements for NDAs in Poland

For NDAs to be enforceable in Poland, they must be:

• Reasonable. The NDA cannot place an undue burden on someone not to share information.

• Specific. The NDA needs to clearly define the kind of information that's confidential and the time frame during which it cannot be disclosed.

• Not outside the public interest. Certain information can't be covered by an NDA. For example, a company can't require employees to sign an NDA to prevent them from disclosing criminal activity by the company.

When would an employee or contractor sign an NDA?

As early as possible. It's common for employees and contractors in Poland to sign NDAs during their onboarding process or when they start a new work contract. An NDA may also be included as part of a new hire's offer letter or employment contract, or as a separate agreement.
