What to Look for in an NDA Before Signing: 8 Red Flags

1. One-way vs. mutual

A mutual NDA protects both parties' information. A one-way (unilateral) NDA protects only theirs. One-way NDAs are normal when only one side is sharing secrets — say, you're evaluating their product. But if you'll also be sharing your processes, pricing, or client information, insist on mutual obligations.

Red flag: A one-way NDA in a relationship where information clearly flows both directions.

2. The definition of "confidential information"

This is the heart of the document. Good definitions are specific: business plans, customer lists, technical specifications, financial data. Dangerous definitions are circular and unlimited: "any information disclosed by Company, in any form, whether or not marked confidential." Under a definition that broad, a casual hallway comment becomes legally protected information you can never use or repeat.

Red flag: No requirement that confidential information be identified, marked, or reasonably understood to be confidential.

3. Missing standard exclusions

Every legitimate NDA excludes information that was already public, that you already knew before disclosure, that you received lawfully from a third party, or that you developed independently. If these exclusions are missing, you could be liable for "disclosing" information that was on the company's own website.

4. Perpetual or undefined terms

Most trade secrets justify 2–5 years of confidentiality. An NDA with no expiration — or "obligations survive indefinitely" — binds you forever. For genuinely permanent secrets like formulas or source code, perpetual terms for those specific items can be reasonable. Perpetual terms for everything are not.

Red flag: No term length stated anywhere in the document.

5. Non-competes hiding inside the NDA

This is the big one. Look for language preventing you from "engaging in any business similar to" or "working with competitors of" the disclosing party. That's not confidentiality — that's a non-compete wearing an NDA costume, and it can lock you out of your own industry. Same for non-solicitation clauses (can't hire their people, can't work with their clients) buried in a document labeled "Confidentiality Agreement."

6. IP assignment language

An NDA's job is to protect information, not transfer ownership. If you see "all ideas, suggestions, or feedback provided by Recipient shall become the sole property of Company," then your input during a "casual exploratory conversation" becomes their intellectual property — for free.

Red flag: Any clause assigning ownership of your ideas, feedback, or work product inside an NDA.

7. Injunctive relief with no balance

Standard NDAs let the disclosing party seek an injunction — a court order to stop disclosure. That's normal. What's not: clauses where you waive all defenses, agree damages are "irreparable" automatically, or pay their attorney's fees regardless of outcome.

8. Residuals clauses (when you're the discloser)

If you're the one sharing information, watch for a "residuals" clause — language letting the other party freely use anything their employees "retain in unaided memory." For a technical discussion, that can hollow out the entire NDA. Big companies love these against small partners.
