| You will have to file with the court to have the custody order amended, if the mother is not properly caring for the child, then you can ask for custody. ( which would be a real treat if the 17 year old did not want to come) If she is living with a aunt, or other relation, you will have to try and have custody issues changes, which can effect the support.
But no, you have to pay the support as long as the court order is in place.
I had my boys living with me for two years, it took me almsot 7 months to get child support waived, I had to pay support for 7 months that the kids were living with me. |
