Family courts do not listen to children who are ten years old.They also do not like to move children back and forth. You need to secure a medical opinion letter from a mental health professional about how well the child is doing in your home. You need to avoid "programming" her to how much she would like to stay with you. Judges don't like that. The court focuses on the best interest of the child. It sounds like mother wants to get her hands on child support, not the child. Strongly advise you to use an experienced family lawyer in this dispute especially since NJ courts lean towars the mother. Good luck.
