I guess it's different there than in the states (and it varies from state to state here). Aaralyn's dad is on her birth certificate too but because we were never married, I have full parental rights to her, he has none, legally he would have to take me to court if he wanted that changed. I don't need his permission for anything for her as far as he's concerned.
What happens if he's ordered to pay a certain amount of child support and then doesn't pay??? Can he then lose his parental rights?? From the sounds of it he's not going to be too keen on paying child support regularly so I would not let it end on just the advise that this solicitor gave you. Also, keep documentation of every abusive thing he says or does to you from here on out.
Is your solicitor going to represent you in court??
