Mutual Non-Disclosure Agreement (NDA) — United States

Overview

A mutual non-disclosure agreement (NDA) is a contract under which two parties each agree to protect confidential information disclosed by the other. Unlike a one-way NDA (used where only one party discloses sensitive information), a mutual NDA is appropriate where both sides will share confidential material — for example during exploratory partnership talks, a potential joint venture, or due diligence ahead of a transaction. Confidentiality protection in the United States comes from two overlapping sources: the contract itself, and trade secret law, which since 2016 includes a federal private right of action under the Defend Trade Secrets Act (DTSA), layered on top of the state-law trade secret statutes that nearly every state has adopted based on the Uniform Trade Secrets Act (UTSA) — with meaningful state-to-state variation (for example, California's version omits some UTSA provisions and interacts differently with its strong public policy against post-employment restraints). When to use it: before sharing sensitive business, technical, financial, or commercial information with another party where both sides will be disclosing information — for instance, initial partnership talks, supplier evaluation, or investment discussions. Parties: two parties, each acting in the dual capacity of "Disclosing Party" and "Receiving Party" depending on which information is being shared. Key clauses: a clear definition of "Confidential Information" (broad enough to capture what matters, but with standard carve-outs for information already public, already known to the recipient, independently developed, or required to be disclosed by law or court order), the permitted purpose for which the information may be used, obligations of confidentiality and limits on onward disclosure (e.g. to employees and advisers on a need-to-know basis, bound by equivalent obligations), the duration of the confidentiality obligation (commonly 2 to 5 years from disclosure, though genuine trade secrets can warrant an indefinite obligation for as long as the information remains secret), and provisions on return or destruction of confidential material on request or termination. Defend Trade Secrets Act whistleblower notice: federal law requires that an NDA (or any other agreement governing trade secrets) include notice of immunity for an individual who discloses a trade secret in confidence to a government official or attorney solely to report a suspected violation of law, or in a court filing made under seal — omitting this notice can limit the exemplary damages and attorneys' fees otherwise available to the disclosing party under the DTSA, so this template includes the required notice. Trade secret status: information only qualifies for trade secret protection if it (1) derives independent economic value from not being generally known, and (2) is subject to reasonable efforts to maintain its secrecy — a well-drafted, consistently enforced NDA is itself strong evidence of those "reasonable efforts," which is one reason to use a written NDA even though an oral confidentiality understanding can, in limited circumstances, also be enforceable. Common pitfalls: a definition of confidential information so broad it is unenforceable or so narrow it fails to cover what actually matters; omitting the DTSA whistleblower notice, which can reduce available remedies; forgetting that an NDA does not itself transfer or license any intellectual property — a separate license or assignment is needed if information will be used to create new IP; and using a mutual NDA in what is actually a one-way disclosure situation, needlessly obliging the party that discloses nothing.

Frequently asked questions

When should I use a mutual NDA instead of a one-way NDA?

Use a mutual NDA when both parties will be sharing confidential information with each other, for example in exploratory partnership talks or due diligence. If only one party is disclosing sensitive information, a one-way NDA that only binds the recipient is more appropriate.

Is an NDA enforceable under US law without any registration?

Yes. There is no registration requirement — an NDA is enforceable as an ordinary contract in every state, and information meeting the legal definition of a trade secret also receives protection under state trade secret statutes and the federal Defend Trade Secrets Act, independent of any contract.

What is the Defend Trade Secrets Act whistleblower notice, and why is it in this NDA?

Federal law requires that agreements governing trade secrets include notice that an individual cannot be held liable for disclosing a trade secret in confidence to report a suspected legal violation to a government official or attorney, or in a sealed court filing. Omitting this notice can limit the exemplary damages and attorneys' fees otherwise available under the Act.

How long should the confidentiality obligation last?

Two to five years is common for general business information. Information that qualifies as a genuine trade secret can warrant an indefinite obligation for as long as it remains secret, since trade secret protection under state and federal law does not expire on a fixed schedule.

Does an NDA transfer any intellectual property rights?

No. An NDA only restricts use and disclosure of information — it does not license or assign any intellectual property. A separate agreement is needed if the parties want to license or transfer IP rights.

Does state law matter for an NDA?

Yes. While most states have adopted a version of the Uniform Trade Secrets Act, there is meaningful state-to-state variation (for example, California's version and its strong public policy against restraints on trade), so the governing state matters and this template should be reviewed against that state's law.
