Child support, though, can get paid by one parent to the New York State Child Support Processing Center (which in many states is called Friend of the Court) and the money is then recorded as received by the paying parent and disbursed to the other parent.
I think that is what Cleaninghotline was probably referencing.
If so, the son can request a print off of all payments made to the state to show he is not in arrears. There are also legal services available for child support issues (see the link below) but it is not
free assistance.
It would not be
unheard of for a state child support collection unit to err in their data entry. Whether that happened here is a question mark.
