US NDA Clause Standards — Key Legal Requirements & Red Flags

Common Law · NDA Clause Standards

Continuously updated — last refreshed July 2026

In the United States, NDAs are governed primarily by state trade secret laws (most states have adopted the Uniform Trade Secrets Act) and the federal Defend Trade Secrets Act (DTSA). Courts require confidential information to be identified with 'reasonable particularity' and subject to 'reasonable efforts' to maintain secrecy. Below are the standard NDA clauses and what to look for under US law.

Clause-by-Clause Standards

Definition of Confidential Information

Market Standard

"Confidential Information" means information disclosed in writing and marked "Confidential" at the time of disclosure. Oral disclosures must be confirmed in writing within thirty (30) days to qualify for protection.

Fairness Test

Must require written marking. Oral information must be confirmed within 30 days. A purely subjective standard ('anything the Disclosing Party considers confidential') is a red flag.

Red Flags to Watch For

HIGH

Contains: any and all information

Overly broad — covers publicly available info. UTSA §1(4) requires 'reasonable particularity.'

MEDIUM

Contains: whether oral or written

Without a written confirmation window, casual conversations become legally binding secrets.

HIGH

Contains: considers confidential

Subjective standard — the Disclosing Party can unilaterally designate anything as confidential after the fact.

Legal References

Uniform Trade Secrets Act §1(4)

Requires information to be subject to 'reasonable efforts to maintain its secrecy' to qualify as a trade secret.

Defend Trade Secrets Act, 18 USC §1839(3)

Federal definition requires 'reasonable measures to keep secret' plus independent economic value from not being generally known.

Exclusions from Confidential Information

Market Standard

Confidentiality obligations do not apply to information that: (a) is or becomes publicly available; (b) was known to the Receiving Party prior to disclosure; (c) is rightfully received from a third party without restriction; (d) is independently developed without use of or reference to the Confidential Information.

Fairness Test

All four standard carve-outs must be present. The independent development exclusion is critical — without it, you can be sued for creating something similar through your own work.

Red Flags to Watch For

HIGH

Contains: missing independent development

Without this, you can be sued for independently creating something similar — a complete defense under trade secret law.

MEDIUM

Contains: missing third-party disclosure

You could be liable for information you legitimately received from someone else.

Legal References

Restatement (Third) of Unfair Competition §41

Independent development is a complete defense to trade secret misappropriation — this exclusion preserves that right in the contract.

Obligations of the Receiving Party

Market Standard

The Receiving Party shall use at least the same degree of care to protect the Disclosing Party's Confidential Information as it uses to protect its own confidential information of like importance, but in no event less than reasonable care.

Fairness Test

'Reasonable care' is the market standard. 'Best efforts' or 'utmost care' imposes a higher, potentially unlimited burden.

Red Flags to Watch For

MEDIUM

Contains: best efforts

Higher standard than 'reasonable care' — courts have interpreted 'best efforts' to require actions against a party's own commercial interests.

Term and Duration

Market Standard

Confidentiality obligations shall survive for three (3) years from the date of disclosure, except for trade secrets which shall be protected for so long as they remain trade secrets under applicable law.

Fairness Test

2-5 years is standard for general business information. Perpetual obligations are only appropriate for information that qualifies as a trade secret.

Red Flags to Watch For

HIGH

Contains: in perpetuity

Perpetual obligation for non-trade-secret information is unreasonable and may be unenforceable in some states.

Legal References

Uniform Trade Secrets Act §1

Only trade secrets merit perpetual protection. General business information should have a reasonable time limit.

Governing Law and Jurisdiction

Market Standard

This Agreement shall be governed by the laws of [State]. The parties consent to the jurisdiction of the state and federal courts located in [County], [State], provided that either party may seek injunctive relief in any court of competent jurisdiction.

Fairness Test

Mutual consent to jurisdiction is standard. 'Exclusive' jurisdiction in a distant forum is a red flag if you are not based there. Delaware is a common neutral choice for commercial contracts.

Red Flags to Watch For

MEDIUM

Contains: exclusive jurisdiction

Forces all disputes into a single distant forum. Remove 'exclusive' to allow either party to bring suit where they are located.

Remedies for Breach

Market Standard

The Receiving Party acknowledges that money damages would be inadequate for any breach and that the Disclosing Party shall be entitled to seek injunctive relief, in addition to all other remedies available at law or in equity.

Fairness Test

Injunctive relief is standard in NDAs. 'Without bond' language and liquidated damages are red flags.

Red Flags to Watch For

LOW

Contains: without bond

Lowers the bar for emergency court orders. A wrongful injunction can disrupt your business even if the claim fails.

MEDIUM

Contains: liquidated damages

Preset dollar amounts per violation — damages should be based on actual harm, not a penalty.

Legal References

Federal Rule of Civil Procedure 65(c)

Courts may require a bond for preliminary injunctions. Contractual waiver of this requirement shifts risk to the Receiving Party.
