NDA Guide: Protect Your Business Secrets

A one-way (unilateral) NDA protects one party\'s information. Use when only you are sharing sensitive material — e.g., disclosing your product to a potential investor or vendor.

A mutual (bilateral) NDA protects both parties. Use when both sides will share sensitive information — e.g., two companies exploring a partnership, or an acquisition due-diligence process.

When in doubt, make it mutual. Counterparties sign faster because the protection is reciprocal.

• Definition of "Confidential Information" — broad enough to cover everything you might share, narrow enough not to sweep in public info.
• Permitted use — recipient may use info only for evaluating or performing the defined purpose.
• Exclusions — already public, independently developed, rightfully received from a third party, disclosed with written permission.
• Duration of the obligation (typically 2–5 years; indefinite for trade secrets).
• Return or destruction of materials on demand or termination.
• Remedies — including injunctive relief (critical) and attorneys\' fees.
• Governing law and venue.
• No license — the NDA does not transfer any IP rights.
• Non-solicitation (optional) — recipient may not hire away your employees for a period.

Courts enforce NDAs that are reasonable in scope and duration and that protect a legitimate business interest. They strike down NDAs that:

• Try to protect publicly available information
• Last too long for the kind of information protected
• Bar the recipient from working in the industry at all (that\'s a non-compete, not an NDA)
• Conflict with whistleblower protections or securities disclosure obligations
• Violate the federal Defend Trade Secrets Act immunity notice requirement (2016)

Always include the DTSA immunity notice: the recipient is immune from liability for confidential disclosures to government officials in connection with reporting suspected violations of law.

• Signing an NDA after the disclosure happens (too late)
• No clear definition of what is confidential (courts refuse to guess)
• Mixing NDA terms with a non-compete in the same document (increases strike risk)
• Indefinite duration for ordinary business info (courts limit to "reasonable" term)
• Skipping injunctive relief language (makes money damages the only remedy)
• Forgetting to mark materials "Confidential" when delivered
