An NDA review takes about 10 minutes if you check eight things: who is bound, how confidential information is defined, the exclusions, permitted use, the term, return of information, residuals, and any hidden restrictions like a non-solicit. NDAs are the most-signed and least-read contracts in business. Most are fine. The ones that are not usually hide the problem in a broad definition or a clause that has nothing to do with confidentiality.
This guide walks through what a non disclosure agreement looks like, mutual vs one-way NDAs, the clauses to check, red flags, sample pushback wording, and how to review an NDA with AI. We make AI Contract Review, which can do the first pass. We say where it fits and when you need a lawyer instead.
What an NDA looks like (structure walk-through)
Most NDAs run one to five pages and follow the same order:
- Parties and date. Who is signing, as which legal entity.
- Purpose. Why information is being shared, for example "evaluating a possible partnership".
- Definition of confidential information. What is protected.
- Exclusions. What is not protected.
- Obligations. Keep it secret, use it only for the purpose, protect it with reasonable care.
- Permitted disclosures. Employees and advisers who need to know; disclosures required by law.
- Term. How long the agreement and the obligations last.
- Return or destruction. What happens to the information at the end.
- Remedies, governing law and signatures.
If an NDA you are given has sections that do not fit this list, read those first. That is where surprises live.
Mutual vs one-way NDAs
A one-way NDA protects only the party sharing information. It is normal when only one side discloses, such as a company sharing product plans with a contractor.
A mutual NDA protects both sides. It fits partnerships, joint pitches and sales conversations where both sides share something.
A quick example. A founder meets a potential distribution partner. The partner sends a one-way NDA protecting only its own information. But the founder will share pricing and customer lists too. The fix is simple: ask for the NDA to be made mutual. Most companies agree, because a mutual NDA costs them nothing.
When you are about to sign a one-way NDA, check which way it runs. If you are the receiving party only, all the obligations fall on you.
The 8 clauses to check
| Clause | Standard | Red flag | Suggested edit |
|---|---|---|---|
| 1. Definition of confidential information | Information marked confidential, or that a reasonable person would see as confidential, shared for the purpose | "All information of any kind", whether or not marked, including anything you already knew | Limit to information disclosed for the purpose and marked or reasonably understood as confidential |
| 2. Exclusions | Public information, already known, independently developed, received from a third party lawfully | No exclusions, or only some of them | Add the four standard exclusions |
| 3. Permitted use and disclosure | Use only for the purpose; share with staff and advisers who need to know | No right to tell your lawyer, accountant or investors | Allow disclosure to employees, advisers and investors under similar obligations |
| 4. Term | Agreement term of 1 to 3 years; obligations survive for a set period after (trade secrets longer) | Obligations last forever for all information | A fixed survival period, with longer protection only for trade secrets |
| 5. Return or destruction | Return or destroy on request; keep archival copies required by law or backups | Certify destruction of everything, including automatic backups | Allow retention of copies in routine backups and as required by law, still kept confidential |
| 6. Residuals | Absent, or limited to general skills and know-how | Broad residuals clause letting the other side use anything "retained in memory" | Delete it, or limit it to general knowledge with no right to use specific information |
| 7. Hidden restrictions | None; an NDA is about confidentiality | Non-solicit, non-compete, exclusivity or IP assignment inside the NDA | Delete, or narrow in scope and time |
| 8. Remedies | Right to seek an injunction for breach | Fixed penalties, one-way indemnity, or a waiver of your defenses | Keep injunctive relief, remove penalties and one-way indemnities |
Also check governing law and venue. An NDA that sends every dispute to courts across the country is a small but real cost.
Red flags: hidden non-solicits, endless terms, broad definitions
- Hidden non-solicits. A clause saying you will not hire or approach the other side's employees or customers for two years. That is a business restriction, not confidentiality, and it often slips through because nobody expects it in an NDA.
- Non-competes. Any clause stopping you from working in an area or with certain clients. This is the clearest sign you need a lawyer.
- Endless terms. Obligations that never end for all information. Trade secrets can justify long protection; your meeting notes cannot.
- Broad definitions. "All information disclosed in any form, whether or not marked" makes it hard to know what you can never mention again.
- IP assignment or feedback clauses. Wording that gives the other side ownership of ideas or feedback you share.
- No exclusions. Without them, information you already knew can become "theirs".
How to push back (sample wording)
Pushing back on an NDA is normal and rarely slows a deal. Keep it short and specific. Sample wording you can adapt:
- Make it mutual: "Since we will both be sharing information, could we make this mutual? Happy to use the same terms in both directions."
- Narrow the definition: "Could we limit Confidential Information to information disclosed for the purpose and marked or reasonably understood as confidential?"
- Remove a non-solicit: "The non-solicit in section 7 goes beyond confidentiality, so we would like to remove it. We are comfortable with the confidentiality terms."
- Fix the term: "Could the obligations survive for two years after termination, with trade secrets protected for as long as they remain trade secrets?"
Reviewing an NDA with AI in 2 minutes
AI is well suited to NDAs: they are short, standard, and the risks are well known. With AI Contract Review you upload the NDA as a PDF or Word file and get a summary card (parties, term, termination), the risky clauses with the exact quote and a plain-English explanation, and a list of changes to ask for. The point is to catch the clauses in the red flag list above, such as a non-solicit tucked into section 7, before you sign on autopilot.
Two cautions. First, check whether you are allowed to share the NDA itself; some restrict disclosure of their own terms. Second, AI review is not legal advice. Use it to know what to ask, not as the final word.
The summary card is free for 3 documents a month at contracts.kissmyskills.com, no sign-in needed. Unlimited contracts and the full risk review through your own Claude come with the KissMySkills All-Access subscription at $15 a month or $129 a year.

Where lawyers and templates win
A lawyer wins when the NDA hides a non-compete or non-solicit you cannot remove, or when it is tied to an acquisition, investment or other major deal. Standard NDA templates from reputable legal sites win when you need to draft your own NDA rather than review someone else's; our roundup of AI legal document generators covers what you can safely generate yourself. Our tool does neither drafting nor negotiation.
When to get a lawyer
- The NDA includes a non-compete, non-solicit or exclusivity you cannot get removed.
- It is part of an acquisition, investment or joint venture.
- You will receive information that could later overlap with your own product.
- It includes penalties, indemnities or IP assignment.
- The other side refuses reasonable edits and the relationship matters.

FAQ
What should you look for in a non disclosure agreement?
Check who is bound (mutual or one-way), how broadly confidential information is defined, the standard exclusions, what you may use the information for and who you may share it with, how long the obligations last, what happens to the information at the end, and the remedies. Then look for anything that is not about confidentiality at all, such as non-solicit, non-compete or IP assignment clauses.
What does a non disclosure agreement look like?
Most NDAs are one to five pages: the parties and date, the purpose of sharing information, a definition of confidential information, exclusions, obligations of the receiving party, permitted disclosures, term, return or destruction of information, remedies, governing law, and signatures. A mutual NDA protects both sides; a one-way NDA protects only the party disclosing information.
How much does a lawyer charge to review a contract?
It depends on the lawyer, the city and the document. Many lawyers bill by the hour; some offer a flat fee for short, standard documents such as NDAs. Ask for a flat quote upfront and send a short list of specific questions with the NDA to keep the review quick.
