Share a reminder list on iCloud.com
You can share reminder lists with other iCloud users. Only the owner of a shared list can add and delete people who are sharing the list.
People you share a list with can view the list, mark reminders as completed, add and delete reminders, and see who else is sharing the list.
Note: If you are using updated reminders, you might not see all of your shared lists on iCloud.com. You also cannot manage sharing on the web. Use the Reminders app on a device with iOS 13, iPadOS 13, macOS 10.15 or later to see and manage all your shared lists.
