1. How is "Confidential Information" defined — narrowly, or as everything?
The definition decides how much of the agreement actually binds you. A tight NDA covers information that is marked confidential or clearly sensitive, and carves out the obvious exceptions. An overbroad one sweeps in anything you learn "in connection with" the relationship — including things you already knew, things that become public, and things you develop independently — so almost any later dispute can be framed as a breach.
Watch for: Definitions that cover "all information disclosed, in any form, whether or not marked confidential," with no carve-outs for information that is already public, already in your possession, independently developed, or lawfully received from a third party.
Ask for: A definition limited to information marked confidential (or identified as such within a set number of days if disclosed orally), plus the standard carve-outs for public, pre-existing, independently developed, and third-party information — and a carve-out for disclosures you are legally compelled to make.
2. Is it one-way or mutual — and are you the only one bound?
A one-way (unilateral) NDA binds only the receiving party. That is fine when only one side is sharing secrets, but the version handed to you often assumes you are the only one disclosing nothing and receiving everything — so all the obligations, and all the risk, land on you. If both sides will actually exchange sensitive information, the agreement should bind both.
Watch for: A one-way structure in a situation where you will also be sharing your own confidential information, and defined terms like "Discloser" and "Recipient" that quietly cast you as the only Recipient.
Ask for: A mutual NDA when both sides exchange information, so the same protections and limits apply to each of you. If it stays one-way, make sure it matches who is actually disclosing — and that your own information is protected where you share it.
3. How long do the obligations last — is confidentiality perpetual?
Duration has two parts: how long the agreement runs, and how long your confidentiality duty survives after it ends. Many NDAs bind you to keep information secret forever, which is hard to live with and hard to track years later. A defined survival period — commonly two to five years — is more workable, with a narrow exception for genuine trade secrets, which can be protected for as long as they stay secret.
Watch for: Language making confidentiality obligations "perpetual" or "in effect indefinitely" for all information, with no time limit and no distinction between ordinary confidential information and trade secrets.
Ask for: A defined confidentiality period after the agreement ends (for example, two to five years), with a separate, narrower carve-out that lets true trade secrets stay protected for as long as they remain secret — rather than a blanket "forever" on everything.
4. What can you do with the information — and what happens when it ends?
A clean NDA limits use of the information to the stated purpose, and says what happens to it afterward: return or destroy it on request. Two details matter. First, "destroy" should account for routine backups and legal retention you cannot easily purge. Second, watch for a residuals clause — it lets the other side freely use anything their people remember "without reference to" your documents, which can quietly undercut the whole agreement.
Watch for: Use rights broader than the stated purpose, a return-or-destroy demand with no allowance for automatic backups or required retention, and a residuals clause letting the other side use whatever their staff remember from your confidential information.
Ask for: Use strictly limited to the defined purpose, a return-or-destroy obligation that carves out routine backups and legally required copies, and either removal of the residuals clause or a version narrow enough that it does not swallow your protections.
5. What else is smuggled in beyond confidentiality?
An NDA is supposed to be about secrecy. But extra obligations are often folded into the same document, where they are easy to miss: a non-solicit or non-compete, an assignment of intellectual property in anything you discuss, or a broad injunctive-relief and fee-shifting clause that tilts every future dispute toward the other side. These change what you are agreeing to far more than the confidentiality terms do.
Watch for: Non-solicitation or non-compete language, clauses assigning ownership of ideas or IP you create or discuss, an automatic agreement that any breach entitles them to an injunction, and one-sided fee-shifting that makes you pay their legal costs.
Ask for: Strike anything that is not about confidentiality, or negotiate it separately and knowingly — narrow any non-solicit to a reasonable scope and time, remove IP-assignment language from an NDA, and make injunctive-relief and fee-shifting terms mutual rather than one-directional.

Review your NDA freeFrequently asked
What should I check before signing an NDA?
Check five things: how broadly "Confidential Information" is defined and whether it has carve-outs; whether the agreement is one-way or mutual and which side you are on; how long your confidentiality duty lasts, including any "perpetual" language; how the information must be used and returned or destroyed, including any residuals clause; and whether extra terms like a non-solicit, non-compete, or IP assignment have been folded in. Those are where a routine-looking NDA does the most.
What is the difference between a one-way and a mutual NDA?
A one-way (unilateral) NDA binds only the party receiving information, which fits when just one side is sharing secrets. A mutual NDA binds both parties, so the same obligations and protections apply to each. If both sides will actually exchange confidential information, a mutual NDA is usually the fairer fit; if you are handed a one-way version but you are also disclosing, that is worth flagging.
Do I need a lawyer to review an NDA?
For a routine mutual NDA, a fast side-aware review can flag the risky terms — an overbroad definition, perpetual confidentiality, a buried non-compete — in minutes, which is often enough to sign or ask for changes with confidence. For an NDA tied to a major deal, or one that doubles as a non-compete or IP assignment, the stakes are higher and consulting a qualified attorney is worth it.
