Legal Question in Family Law in North Carolina

You really can't do anything because you don't have what is known as standing even though you are presumably the beneficiary of the child support. Your mother however, should biddy bop down to her local child support enforcement office. They are slow but if your father is working a legitimate job they will eventually get him paying and most likely catch up the arrears. Another option would be for her to hire an attorney. This has the potential to be a bit faster but will certainly be more expensive.
