You may need to redline a contrast to make someone see what’s been changed, suggested, or removed with more certainty and less back-and-forth. This post explains what redlining of contracts is and offers a guide on how to redline a contract using MiniTool PDF Editor and Microsoft Word.

What Is Redlining in Contracts?

Redlining of contracts refers to marking a contract to indicate modifications, changes, or suggestions, much like marking printed documents with a red pen.

In fact, the term originates from this practice. When contracts were mostly in paper form, lawyers would actually use red pens to cross out clauses, add annotations, or mark wording they disagreed with.

In modern business scenarios, most contracts are shared as PDF (finalized or circulated official draft) or Word (editable original draft) documents, meaning annotation is also done electronically.

Redlining is a crucial part of the contract review process. They help both parties understand what has changed and why, without having to compare multiple versions.

Essentially, it's a clearer and faster way to manage contracts, facilitating smoother contract negotiations.

Now, follow the step-by-step tutorial for redlining contracts in PDF and Word.

To redline a Word contract effectively, you use the Track Changes feature located under the Review tab. This tool automatically records every edit and appears as strikethroughs.

To redline a contract in Word, here are the steps:

  1. Open your Word document, go to the Review tab, and click Track Changes.
  2. Select All Markup from the dropdown menu to see exactly what is being added (underlined) or removed (strikethrough).
  3. Type new text, delete old text, or move sections. You will see the words marked with a red strikethrough and the added words in red font color.
  4. Select text, click New Comment to clarify reasons for changes.
  5. Save the document.
Tips:
To accept or reject the proposed changes if you received a redlined document, go to the Review tab. Look at the Changes section. MS Word will find the first redlined text. Review it and click Accept or Reject based on your decision.
The Microsoft Word interface with the Review and Track Changes option selected.

  2. Select your Original document (earlier version) and the Revised document (newer version).
  3. Click OK to generate a new document that automatically marks all differences as tracked changes.

How to Redline a Contract FAQ

1. What is the difference between redlining and blacklining?
Redlining is the active process of marking proposed changes during negotiation. Blacklining is a static comparison between two complete versions of a document to highlight all differences at once, often using Word’s "Compare" tool.
2. Is a redlined contract legally binding?
No. A redline is a work-in-progress negotiation draft. It only becomes legally binding once all parties agree to a final version and formally execute it.
3. How do I redline a scanned PDF?
If a PDF is just an image (scanned), you cannot use standard markup tools directly. You should use an OCR (Optical Character Recognition) tool to convert the PDF to an editable document first.
4. Is redlining a PDF better or worse than Word?
Redlining a PDF is more manual and time-consuming because it does not automatically track revisions. However, some attorneys prefer it for security and control to ensure the core document structure remains "locked".
