How to annotate a contract
To annotate a contract, open it in a PDF viewer, Word, or Google Docs and use the comment or highlight tools to mark proposed changes, flag clauses, and add notes — without altering the underlying text. To have the other party annotate it, share a link they can open and mark up in their browser without downloading or installing anything.
In Adobe Acrobat or a browser PDF viewer (free)
Open the contract PDF in Acrobat (free Reader or paid) or drag it onto a browser tab. Click the Comment toolbar — you get a Highlight tool, a Sticky Note pin, and a Text Annotation field. Select the clause you want to flag, apply a highlight, then right-click → Add Note to explain the proposed change. Use a consistent color system: yellow for clarification, red for a clause you want removed or reworded. File → Save As preserves the annotation layer. The recipient opens the same file and sees your notes alongside the original text.
In Microsoft Word (Track Changes)
If the contract is a .docx, use Word's Track Changes mode: Review → Track Changes (⌘ Shift E on Mac, Ctrl Shift E on Windows). Every deletion shows as red strikethrough, every insertion as underline. To add a note without altering text, select a clause and click New Comment in the Review tab. Send the file back with Track Changes on — the other party accepts or rejects each edit individually. If the contract is a PDF, convert it first via File → Open → select the PDF in Word, then mark it up and share the .docx.
In Google Docs (Suggesting mode)
Upload a .docx to Google Docs and switch to Suggesting mode (pencil icon → Suggesting). Every edit becomes a color-coded suggestion tied to your name — the other party accepts or rejects each one. For notes that don't change the text, highlight a clause and press ⌘ Option M (Mac) or Ctrl Alt M (Windows) to add an inline comment. Fastest when both parties have a Google account and the contract is not a locked PDF.
When the client needs to annotate it (not you)
The fragile step in every contract review is getting the other party's markup back. Emailing a PDF results in two annotated copies that you reconcile manually. Emailing a .docx file means the client needs Word — and the formatting sometimes breaks on re-open. The cleaner path: share the contract as a link the client opens in their browser. They pin a note to the exact clause they want changed, you see it in one thread, and no one re-emails a file. This works whether the other party is on a phone, a Mac, or a Windows machine with no software installed.
If you're a designer sending your own contract for client sign-off — and the typical response is a vague email like 'can we change the revision clause?' rather than a specific annotation — try sharing it as a Drafty link instead. Your client clicks the clause they mean and pins a note right there. No downloaded file bouncing back over email, no guessing which paragraph they meant. Every comment lands anchored to the exact clause, in one thread, with no account required on their end.

- What does it mean to annotate a contract?
- Annotating a contract means adding highlights, sticky notes, comments, or tracked changes to the document without altering the underlying text. It's how you flag clauses you want changed, explain your reasoning, or mark sections for discussion — without sending a replacement draft.
- What is the difference between annotating and redlining a contract?
- Annotating adds comments and highlights alongside the text. Redlining specifically marks proposed text changes — deletions in strikethrough, insertions underlined — so the other party can accept or reject each edit individually. Word's Track Changes and Google Docs' Suggesting mode are redlining tools; PDF sticky notes are annotation-only.
- How do I annotate a contract PDF without Adobe Acrobat?
- Drag the PDF onto a browser tab — Chrome, Firefox, and Edge all have built-in PDF viewers with a basic comment toolbar. For more control, free web tools like Smallpdf or Lumin PDF let you highlight and add notes without installing software. Download the annotated copy when done.
- How do I share a contract for someone else to annotate?
- Email a PDF if the other party has a PDF tool. Share a Google Doc if both parties have Google accounts. For the cleanest experience — especially with clients who aren't technical — share a link they can open in any browser and annotate with no download or account required.
- Can I annotate a contract on my phone?
- Yes. On iPhone, open the PDF in Files or Safari, tap the pencil icon, and use iOS Markup to highlight and add text notes. On Android, open the PDF in Google Drive and use the Comment tool. For a contract you want someone else to mark up, a browser-based shared link is more reliable than a PDF on mobile — markup tools vary widely across Android devices.
- How do I keep everyone's contract annotations in one place?
- Email chains don't work — each party annotates their own copy and you end up reconciling two files. A shared link or a single Google Doc with comments enabled keeps every annotation on one document. Whoever reviews last sees all previous notes in context.
