If you're a member of a Dropbox team account, you can easily transfer ownership of a Paper doc to another member of the same team. Team admins can also transfer ownership of any doc that they currently have access to.
To transfer doc ownership:
- Open a Paper doc.
- Click Invite.
- Click the dropdown beside the name of the person you'd like to transfer ownership to.
- If you don't see their name, share the doc using their email address first.
- Select Make owner.
