My ex and I are apart for about six years, never finalized the divorce. He is not a dad in any sense of the word. Would like to pay the least possible. Does not visit his kids other than 3 hours once a week. That's it.

I had a lawyer until now but it is becoming tooooooo costly. So at my next court appearance I will present myself pro se. Would appreciate any advice. I do feel able to tackle it at this point.
