Hello... I am wondering if it would be in my childs best interest to file for child support payments from my ex. We have been apart since she was a baby. He started by paying $325 for a year then it went down to $250 for a few years which I verbally agreed to. The last 7 years it has dwindled and he only pays $50 here and there when he feels like it. She is 17 now. I have been very ill for the past 3 years so I was not able to look into this. Is it too late? What should my first step be? I am really hoping he will help with her future education. I need to get something in place. Help!
