I'm writing this post on behalf of my partner. In his previous relationship he fathered a child. His ex partner left when she was pregnant and didn't allow him to know where she went. Through Facebook we have found photos of his daughter and a rough location, which is in Queensland. We're wondering what legal right's he has to track down his daughter and have contact with her if the mother didn't put him on the birth certificate. It's breaking his heart and it's not fair. Whilst I am prepared to do whatever I can to assist and whatever it takes, I am out of my depth when it comes to family law. Thank you for your help.
