“My son’s father and I were never married. I have never taken him to court for child support. My son is 18. His father has contributed in the past to his tuition and general support. My son is now going to college full time and his father is not giving any financial assistance at all. Can I file for child support now for the first time? I LIVE IN NEW YORK CITY.”

Likely not. In most jurisdictions an initial action for the support of a child cannot be commenced after the child has reached majority (18).
