Two parties sharing confidential information
Free Mutual NDA Template
A mutual non-disclosure agreement (mutual NDA) protects confidential information that two parties share with each other, in both directions, while they explore or run a working relationship. Use this guide to understand what a mutual NDA should cover and what to include before you sign one.
What a mutual NDA is
A mutual NDA, sometimes called a two-way or bilateral NDA, is an agreement where both sides expect to disclose confidential information and both sides agree to protect it. It differs from a one-way NDA, where only one party shares and the other receives. Choose a mutual NDA when the conversation is genuinely two-sided, for example a partnership discussion, a vendor evaluation, or a potential acquisition.
When to use one
Sign a mutual NDA before you exchange anything sensitive: product roadmaps, pricing, customer data, source code, financials, or strategy. The point is to set expectations before the information changes hands, not after.
The key clauses to look for
Most mutual NDAs share a common structure. Each clause exists to answer a practical question about how the confidential information is handled.
- Definition of confidential information, and what is excluded (public information, information already known, independently developed information).
- Permitted use, which limits the information to the stated purpose only.
- Obligations of the receiving party to protect the information with reasonable care.
- Term and survival, which set how long the duty of confidentiality lasts.
- Return or destruction of materials when the relationship ends.
- Carve-outs for disclosures required by law.
What to include
- The full legal names of both parties
- A clear definition of confidential information
- Standard exclusions (public, already known, independently developed)
- The permitted purpose for which information may be used
- The confidentiality period and any survival after termination
- Return or destruction of confidential materials
- Governing law and how disputes are handled
Frequently asked questions
What is the difference between a mutual NDA and a one-way NDA?
A mutual NDA protects information disclosed by both parties, while a one-way (unilateral) NDA only protects information disclosed by one party to the other. Use a mutual NDA when both sides will be sharing sensitive information.
How long does a mutual NDA last?
The agreement term is often one to five years, but the duty to protect confidential information can survive longer, especially for trade secrets. The NDA should state both the term and how long confidentiality obligations continue after it ends.
What should be excluded from confidential information?
Standard exclusions cover information that is already public, that the receiving party already knew, that it independently developed without using the disclosed information, or that it rightfully received from a third party. These carve-outs keep the NDA fair and enforceable.
Is a mutual NDA legally binding?
A signed NDA is generally a binding contract, but enforceability depends on its terms and the law of the relevant jurisdiction. This guide is general information, not legal advice. Have a qualified professional review any agreement for your specific situation before you rely on it.
