So I've recently tracked down my fob, I knew who he was I just had no contact details for him (it was a one night stand) so now he knows he has a child except it hasn't sunk in and he mentioned a DNA test to confirm it. The problem is we both can't afford it I'm a single mum of two and he is unemployed atm. Would centrelink help at all? Legal aid? I really want my child to have a relationship with its dad and would like him to be on the birth cert can I even change that?
