What is document and contract redlining?

In document management and collaboration process, redlining refers to marking text that has been edited. Typically, redlining is used when two or more people are working on a document together; each individual can redline the text that was added or edited. The redlined text will then appear in a special color (or as bold) so that others can see the changes that have been made

The traditional redlining process typically takes two files as input, compares them to find the largest and nearest blocks of common text, and showing the rest as either added or deleted.  The process works best for documents that are similar, for instance, versions of the same contract or offering. The output is a third file, with the added and deleted text highlighted per user’s request in a format. Typically, the added text might be shown bold, double-underline, surrounded by square brackets; deleted text might be shown strike-through, surrounded by curly brackets.

When is document and contract redlining required?

Document redlining is necessary when you are reviewing or negotiating with someone on a document, or when you are editing a document with markup for a counterparty in order to allow them to see where you have made changes. Other times, you can use it when reviewing and editing the writings of your colleagues to whom you have delegated tasks such as drafting reports, meeting minutes, project plans and other documents for review. By using the redlining and track changes, you can easily see the changes and save time by not having to review the entire document again.

The challenges with traditional ways of doing document change tracking

Difficult to read: As the number of changes in the document grows, it becomes difficult to read the document and makes it harder to find spelling errors or spacing problems.

Leftover document metadata – Track changes and document comparison often leaves behind a trail of metadata that could contain sensitive information. Hence it is critical that all metadata is removed before sending the document across. This requires additional steps and slows down the process.

Forgetting to turn on track changes  – People who are unfamiliar with the track changes function often forget to turn it on and hence any subsequent changes will not be tracked. This makes it harder for the next stage of review, forcing you to read the entire document to see what has changed.

Loss of Formatting: Accepting changes can cause loss of many types of formatting and may require significant effort to remediate these. Renumbering the document after track changes are accepted can be quite a difficult task. Many times, conversion from Word to any other systems break any special formatting (footnotes, special numbering schemes, etc.)


Desktop only – Redline does not always appear on all devices. As a result, you need to wait until you are in front of your computer in order to see the documents and track changes.

Best practices for document redlining

  • For transactional document redlining (read contracts, agreements), it is important to attempt to build a dialog with your counterparty early on in the process. Try to understand the human element of the document negotiation process and determine what personality type you are dealing with.
  • You have to understand that in the end, it is your job and accountability to ensure that you don’t sign (or make your executives sign) on the dotted line unless you are completely sure that the document contains exactly the language you intended to sign on.
  • Set your priorities correctly. Most often we find that the following order of priorities will serve you the best:
    • Compliance first: Use the set of processes and tools that help you ensure that documents meet compliance criteria. Automated tracking of clauses and deviation from standards is a necessity.
    • Confidence: You must be confident about full visibility and trackability of all of the changes that have been made to the document. There should be no unexplained variances
    • Courtesy: Be courteous to your counterparty by offering them the ability to see a redlined copy, clean copy and editable copy, so that they don’t have to repeat the arduous process of redlining and document comparison
  • If you must use MS Word and email  or any other software that does not allow multi-party automatic redlining, consider using the following best practices:
    • Turn on track changes but edit the document without showing markups. This way you can catch spelling or spacing issues and read the document much easier.
    • If you are sending a document via email, you want to ensure the recipient doesn’t turn off track changes
    • Ensure that you or someone on your team scrubs and cleans the document metadata before sending it across to the counterparty
    • Don’t forget to send the counterparty both a redline and a clean editable version of the revised document.
