If your daughter and you move in with the father whom is paying child support is he still oligated to do so?

The courts are the ones who award the support to the mother. If the father, all of a sudden, begins supporting the mother and child, he is still obligated to pay support according to the court. That's because the courts don't know about it. They person involved would have to have the support removed at the court level. But morally speaking, he does not need to pay the support and if he doesn't, wouldn't get in any trouble unless the mother turns him in.
