Comments and @mentions on legal matters in Notion

Comments, @mentions and reminders in MatterOS are Notion's own features. Put discussion on the matter page or the specific action, @mention the person you need, and add a reminder date. The template provides the pages to comment on; Notion provides the notifications.

A comment routine that keeps the record clean

  1. Comment on the object the question is about, not in a chat thread nobody will find later.
  2. Start with the @mention and the ask: who, what, by when.
  3. When the answer changes the plan, update the matter or action and resolve the comment.
  4. At matter close, skim the resolved comments for anything worth saving to Research.

A good test is the one the Matter Method gives for the Team piece: could someone else carry this matter from what is on the page?

Handover and delegation

When you delegate, assign the Action to the person, @mention them in a comment with the context, and add a handover note on the matter. Our delegation guide goes through the pattern.

Limits to know

Notion notifications are not an audit trail, and comment history is not a reliable record of advice given. MatterOS adds no notification rules of its own. Guests see comments only if your sharing settings allow it, so check before using comments with clients.

Frequently asked questions

Does MatterOS have its own commenting?
No. It uses Notion's comments and @mentions on its pages.
Can I @mention a client?
Only if they are a Notion user with access to the page. Review what a guest can see first.
Are reminders reliable for court deadlines?
Treat them as a convenience. Use your firm's formal deadline process as well.
Do comments show up on the dashboard?
No. The dashboard shows database views, not comment threads.
