How do I change my child's gamertag?

Hello KellyGww!

You have 02 ways to make this change,
01º) You can change the current Gamertag linked to your personal email by another, thus releasing that gamertag to your child.
Here's how to do it here:

Or

02º) You can change the email linked to the Gamertag that you want to "preserve", changing the current email to one that belongs to your child.

Because.it's.not.if you changed before

But if you had been given a random.gamertag

Since you have.a custom. Gamertag. Already you don't qualify

Hi. My name is Mel and I am an independent advisor. Because you already have a custom gamertag it means u have to pay to change it. You could try xbox support and see if they will let u change it free of charge but they will likely say the same thing. Have a lovely day.
