Read more about the non disclosure agreement (NDA) used to protect confidential information shared between parties.
Explained – what is a non disclosure agreement?
A non disclosure agreement (abbreviated NDA in English) is a contract between two or more parties that governs how confidential information may be used. Its purpose is to ensure a duty of confidentiality and the protection of trade secrets against unauthorised access or disclosure. The contract may be unilateral NDA, where only one party owes confidentiality, or a mutual NDA, where both parties are bound. NDA agreement documents are common in commercial law, employment contexts and collaborations between companies.
When does a non disclosure agreement become relevant?
An NDA agreement becomes relevant when sensitive information needs to be shared in a business or employment setting. Typical scenarios include recruitment, collaboration between companies, or when appointing a consultant. Non disclosure agreements are also frequently used in due diligence, product development and negotiations on commercial contracts.

- Define clearly the definition of confidential information.
- State the NDA validity period and any exceptions (for example, an NDA duration clause).
- Decide whether the NDA agreement should be unilateral or mutual.
- Set rules on how confidential information may be used and shared.
- Specify consequences in the event of breach of contract.
- Ensure the agreement complies with applicable law.
- Use a contract lawyer for support with drafting, review or negotiation.
A clear and properly drafted confidentiality undertaking reduces the risk of disputes and unauthorised disclosure of sensitive information.
