My 11 year old nephew is unhappy at home with mum and wants to live with his dad. He keeps running away as he says his mum doesn't listen to him. His mum is in a relationship where her partner does not spend time with the children and he is unhappy about a forthcoming marriage. His mum and dad were never married and she is fickle about when he can see the children. What are my nephews rights? At what age can he choose to live with his dad? Does dad have to file for parental rights or a residency order? Thanks
