Contract redlining best practices: 7 rules from in-house counsel

Redlining is communication, not editing

A redline is a conversation in Track Changes. The point isn't to produce the perfect document on the first pass — it's to surface your priorities, your acceptable trade-offs, and your hard limits in a form the other side can quickly understand and respond to. A redline that doesn't do those three things will produce more rounds, not fewer.

Rule 1 — Comment first, edit second

On the first round, use comments to raise issues ("Can we revisit the liability cap — 1× is light for a deal of this size") rather than rewriting the clause yourself. This signals openness, surfaces priorities, and avoids burning your one shot at the perfect language before you know whether the other side will engage.

Rule 2 — Bundle issues by section

Don't fire 47 small comments. Group them by section: "Sections 5–7 — three points to discuss," then list them under a single comment. The reviewer on the other side has to triage your changes; bundling makes their job easier and yours.

Rule 3 — Rank your asks in the cover email

Every redline goes with a cover email that says: "Three priority items: (1) cap raised to 12 months of fees, (2) DPA attached, (3) governing law of [your location]. Everything else is preference and we'll defer if it's a hard problem on your side." That ranking is what gets you out of round-five hell.

Rule 4 — Don't argue in the document

Long comments arguing the rationale belong in the cover email or in a Zoom call, not in the document. Comments in the document should be 1–2 sentences each, max. Long arguments in tracked changes are a sign that the conversation should be happening live.

Rule 5 — Match formality to the relationship

An early-stage NDA with a friendly counterparty deserves a friendlier tone than a 100-page enterprise MSA with a Fortune 500 procurement team. Match the tone of your comments and your edits to the relationship. Stiff, formal redlines in casual deals look like overreach.

Rule 6 — Accept their changes you can live with, immediately

When the other side accepts your changes and proposes minor tweaks, accept the tweaks if they're acceptable, in one round, with no further negotiation. The faster you close on agreed sections, the faster you finish.

Rule 7 — Final clean version before signing

Once all changes are agreed, produce a clean version with all changes accepted, no track changes, no comments. Send it as the signing version with a one-line note: "Clean signing version attached, no substantive changes from our agreed v7." Anyone who notices a difference can flag it; otherwise sign.

Tooling that helps

Word's Track Changes is still the standard. For longer negotiations, tools like Litera, Spellbook, and AI-first reviewers like ContractScan AI can auto-compare versions and surface what's changed between rounds. On any contract over 30 pages, an automated diff is a huge time-saver.
