Remove a family member from your family on Xbox One
The primary purpose of creating a family is to make it easier to manage parental controls and online safety for children. You can manage who’s in your family from your Xbox One console, or from any Windows 10 device.
Adults removed from the family no longer can manage the child accounts in the family. However, they'll have full rights to their account and will be able to use home console sharing when signed in to the home console.
Security note If there’s someone in your family you don’t recognize, remove them. If you're a child and the person you don't recognize is listed on your account as your only parent, have your real parent contact Microsoft Support.
