Any way to leave a family without parental consent?

Hi, Chris my name is Jhon, and will be a pleasure help you

If you're over the age of majority (for example, 18 in the U.S.), you can remove yourself from your family group by using a Windows device.

On the console, any other organizer in the family group can remove you. To do so, have them follow the steps in the preceding section.

Note If you're the only organizer in a family group that includes child accounts, first remove the member from the family group. After you’ve removed them, add them to another family group so that they can continue using Xbox services.

To remove yourself online:
Sign in to your family Microsoft account.

Microsoft account

Under your name, select Leave family.

Can you leave an Xbox family :

Sign in with the appropriate account on the console.
Press the Xbox button  to open the guide.

Select Profile & system > Settings > Account > Family settings > Manage family members.

Select the account that you want to remove from the family group.

I hope this helps! Don't hesitate to ask if you have any further questions or need additional clarification.

Remove members : You can remove anyone that didn't need parental consent to join your family group. This includes organizers, members above statutory age, or member accounts in countries without parental consent requirements. To remove members without parental consent:

1. Go to family.microsoft.com.
   
2. Sign in with your Microsoft account.
   
3. On your family's page under the member's name, select More options > Remove from family group, and confirm.

If the date of birth on your Microsoft account shows that you're under a certain age, Xbox is required to request parental consent for you to use Xbox Live.
