Create and manage legal holds

In an Enterprise Grid organisation, anyone with the Legal Holds Admin system role can place a legal hold on specific members to preserve their messages and files in Slack.

What to expect

  • When you create a legal hold, you can include message and file data from all conversations or just the direct messages that a member is a part of.
  • With a hold in place, messages and files sent by all members in a conversation will be saved regardless of retention settings or if members edit or delete any content.
  • Data subject to a legal hold can be accessed from a JSON export or using the Discovery API.
  • If a channel included in a hold is deleted, message and file data won’t be saved. 
  • Messages and files from Slack Connect channels or direct messages are not included in legal holds.

Tip: If you’re an org or workspace primary owner, learn how to assign members to the compliance admin system role.


Create a legal hold

  1. From your desktop, click your workspace name in the sidebar.
  2. Hover over Tools & settings, then click Organisation settings.
  3. Click Security in the left sidebar, then select Legal holds.
  4. Click Create Legal hold.
  5. Name the hold, then add a description if you like.
  6. Select which conversations to include, then add an optional date range.

Tip: A legal hold can have up to 1,000 custodians, but there is no limit on the number of legal holds that you can create. If you reach the custodian limit, you can create a new legal hold for the outstanding members.
