Redlining an NDA means marking up the changes you want before you sign: striking clauses, narrowing definitions, and adding the protections you need. It is normal, expected, and you do not need a lawyer to do a competent job on a routine NDA. Most counterparties are working from a template and assume you will send a round of edits back.

The trick is to be surgical. A wholesale rewrite stalls the deal and signals distrust; a handful of specific, reasonable edits, each with a one-line reason, gets accepted. This guide walks the four passes that catch almost all of the real risk, gives you the exact language to change, and shows how to phrase each ask.

It is general information, not legal advice. For a high-stakes NDA, or one with unusual terms, have a lawyer review your redlines. To find what to change in the first place, run the NDA through ClauseShift: it flags the high-risk clauses and quotes the exact wording, so your redlines target the real problems.

Red flags to watch

Pass 1: narrow the definition of confidential information

The definition is where most NDA risk lives. If it covers everything you receive, you can breach by accident. Narrow it to information that is marked confidential, or clearly non-public and disclosed for the purpose of the deal. This single edit does more than any other to make an NDA safe to sign.

Ask for: Redline the definition to: information marked 'confidential' at disclosure, or that a reasonable person would understand to be confidential given its nature and the circumstances.

Pass 2: add the standard carve-outs

A fair NDA excludes information that is already public, that you already knew, that you develop independently, or that you lawfully receive from someone else, plus disclosures required by law. If these are missing, add them; they are boilerplate and rarely refused.

Ask for: Add a clause excluding information that is public, previously known, independently developed, lawfully received from a third party, or required to be disclosed by law or court order.

Pass 3: put an end date on the term

Indefinite or very long confidentiality terms are hard to live with, especially if you sign many NDAs. Replace 'in perpetuity' or a ten-year term with a defined window, with only genuine trade secrets allowed to last longer.

Ask for: Redline the term to two to five years from disclosure, with an exception that trade secrets remain protected for as long as they qualify as trade secrets.

Pass 4: strike everything that is not about confidentiality

NDAs sometimes carry non-competes, non-solicits, IP assignment, or exclusivity that have nothing to do with keeping a secret. These belong in the main contract, where they can be negotiated and priced, not signed unknowingly on day zero.

Ask for: Strike any non-compete, non-solicit, IP-assignment, or exclusivity language, or move it to the services or employment agreement for separate negotiation.

Make it mutual if you disclose too

A one-way NDA binds only you. If you will share anything sensitive, your rates, methods, proposals, tooling, convert it to a mutual agreement so the same duties protect your side of the conversation.

Ask for: Change the parties so both sides are 'Discloser' and 'Recipient' and the obligations apply equally, if information flows both ways.

Tie remedies to actual harm

Watch for penalty clauses, agreed liquidated damages, or one-directional legal-fee recovery. These raise the cost of even a technical breach far above the real harm. Tie remedies to proven loss and make any fee-shifting mutual.

Ask for: Redline remedies to actual, proven damages, remove fixed penalties, and make any attorney-fee provision reciprocal.

How to phrase a redline so it gets accepted

Every edit should travel with a short, neutral reason. 'Narrowed to marked information so we cannot breach by accident.' 'Added a three-year term.' 'Moved the non-solicit to the services agreement.' A reason turns a redline from a demand into a conversation, and it shows you are being reasonable rather than adversarial.

Send edits as tracked changes in the document plus a two-line summary email of the substantive asks. Keep the number of changes small: three to six meaningful edits get a fast yes, while twenty edits get escalated to a lawyer and delay everyone. If a term is unusual or high-stakes, that is the one to flag for a professional, not the routine carve-outs.

When to redline, when to walk, and when to just sign

For a routine mutual NDA with a sensible definition and a defined term, you can often sign as-is. Redline when the definition is overbroad, the term is indefinite, the agreement is one-way while you are disclosing, or non-confidentiality restrictions are buried inside. Consider walking when a counterparty refuses every reasonable, standard change, that resistance predicts how they will handle scope and payment later.

The fastest way to know which bucket you are in is to run the NDA through ClauseShift first. It scores the overall risk, lists each risky clause in plain English with the exact contract text quoted, and tells you which clauses are standard and safe versus which ones are worth a redline or a hard question.

Pre-signing checklist

The definition is narrowed to marked or clearly non-public information
The standard carve-outs (public, known, independent, legal) are present
The term has a defined end date, not 'indefinite'
No non-compete, non-solicit, IP, or exclusivity language remains
It is mutual if you are also disclosing
Remedies are tied to actual loss, with no fixed penalties
Each change carries a short, neutral reason
Anything unusual or high-stakes is flagged for a lawyer

Frequently asked questions

Can I redline an NDA without a lawyer?

For a routine NDA, yes. Narrowing the definition, adding carve-outs, setting a term, and striking non-confidentiality clauses are standard edits you can make yourself. For unusual or high-stakes terms, have a lawyer review your redlines.

What is the single most important NDA redline?

Narrowing the definition of confidential information. An overbroad definition is what makes an NDA easy to breach by accident; limiting it to marked or clearly non-public material fixes most of the risk in one edit.

How many changes is too many?

Three to six meaningful edits get a fast yes. Twenty edits get escalated to a lawyer and slow everyone down. Prioritize the definition, the term, and any non-confidentiality clauses.

How do I know which clauses to redline?

Run the NDA through ClauseShift. It scores the risk and lists each risky clause in plain English with the exact wording quoted, so you can see precisely what to change before you mark up the document.

Is my document kept private?

ClauseShift does not keep the document you upload, only the report is saved to your account, and it trains no AI of its own on your contracts.
