Hello. I don't quite understand how it's existed legally since 2018 if it wasn't made final until 2021 (making final usually makes it legal!)
. But if you have a court order that says your daughter lives with both parents, it should make no difference what house you live in whatsoever. Up to you if you want to move house. Having said that, your ex might decide to be difficult if she's that way inclined. For example if the accommodation isn't as good, or not child friendly. But technically it's none of her business. Home is where the heart is.
It doesn't change the court order. If your ex wanted to use this to change the court order she'd have to apply to court to have the order varied and I can't see the court being interested in you moving from one house to another.
