My husband has a 9 year old daughter, and the mother is saying that she will take the kid and live in Tasmania. Is there anything my husband can do? There are no family court orders and signed agreements done. My husband gives child support on time and more than what is written on child support assessment. He has a good record and we look after his daughter very well when we have her. Recently, my stepdaughter's mothers boyfriend's cousin tried to sexually assault her but luckily he stopped and the police, detectives, investigators, social workers, counselling were involved. The mother has a history of being bi polar, depression etc. With her metal health illness, she's been in and out of rehab. What can my husband do? Can we have his daughter or can we stop them from leaving if an agreement or if family court orders are in place? What if there's no agreement or family court order in place? As far as I understand, the mother has the custody of children most of the time.
