Legal Question in Family Law in Georgia

If that's what the judge ruled, that's what it is.

You should have included a request to modify child support when you modified custody. Of course, it is not too late. Pay as ordered, but file a petition to modify child support based on the change in custody. If the court issues a new order changing your child support obligation, you can decrease or stop payment. If you try self help, you might find yourself in contempt of court.
