How Long Does An NDA Last? Negotiating A Duration (2026)

What Is a Non-Disclosure Agreement?

An NDA restricts a party’s disclosure of protected information. Businesses often use them to protect trade secrets, and you can also encounter them in certain types of settlements.

For example, many personal injury lawsuits are settled outside of court. As a condition of settling, many defendants will require injured people to sign an NDA that prohibits them from discussing the details of the company’s negligence, the amount of the settlement or the evidence gathered during the investigation.

Typical Duration of Non-Disclosure Agreements

There is no standard duration for non-disclosure agreements. Instead, the duration often depends on the subject matter. For example, a product liability lawsuit settlement might block the disclosure of its terms forever. This prevents the victim from telling others injured by the product how much they received.

Business NDAs (like those often included in an executive employment agreement) usually last 1-5 years. Information like trade secrets might be protected indefinitely. However, product development plans, client lists and other information that can quickly become outdated are often protected for a limited time.

Factors That Influence How Long an NDA Lasts

The release of certain information might be so damaging that the NDA’s term is perpetual. However, other information might not require perpetual protection. For example, financial information might become public in the company’s next shareholder meeting. Any NDA covering that information might only last a few months to a year.

Some states require that NDAs that restrain trade or commerce must have a reasonable duration. For instance, a Florida non-disclosure agreement is subject to Florida Statute section 542.335 that prohibits “overlong” NDAs. Under this statute, a judge can ignore the agreement’s duration and grant only the relief necessary to carry out its purposes.

Another factor that can affect the duration of an NDA is the breadth of the protected information. An NDA for a specific product might be longer than an NDA covering all information learned during a negotiation.

Some unscrupulous employers may count on employees not knowing the law. These employers will sometimes try to convince employees to sign extremely broad, indefinite NDAs.

If one of these NDAs is legally challenged and the court decides it’s not enforceable, a judge might invalidate certain provisions or throw out the whole agreement.

Can an NDA Last Indefinitely?

An NDA can last indefinitely, but it would need to meet certain requirements to be valid. For example, a New York non-disclosure agreement that restrains trade must be “reasonable in time.” Otherwise, the agreement could unfairly limit a former employee from working in their field. NDAs for other reasons, such as the settlement of a lawsuit, can last forever.

To avoid stressful and expensive legal challenges, any business or individual looking to create an NDA should first familiarize themselves with state laws surrounding these agreements.

Likewise, anyone being asked to sign an agreement should understand state limitations on NDAs or consult a lawyer experienced in contract law before signing.

Renewing, Extending and Updating NDAs After Expiration

In most states, indefinite NDAs are subject to intense legal scrutiny, and there’s a greater risk of the contract being thrown out in court. A possible solution to avoiding an indefinite NDA is to impose a specific term and allow renewals or extensions.

For example, a joint venture agreement might restrict disclosures for two years after the venture ends. At that time, the parties might agree to extend or renew the post-venture NDA. These options ensure the proprietary information they developed together remains confidential.

If the terms need to be updated, the parties can either amend the original NDA or execute a new NDA. In either case, all parties must agree to the changes. If only one party wants the changes, there is no new agreement, and the original agreement will apply.
