A.C.
visitation is independent of support. He doesn't have to pay support in order to see his son. If he has not seen his son in the last year b.c of his choice, you can probably start the process to TPR (terminate his parental rights). You will need an attorney to do so. However, if you have blocked him in the last year and he can prove for any reason that you have kept him from seeing his son, then you will probably have a hard time terminating his rights.
