My Son went overseas to New Zealand with my brother to visit my parents. My parents called and told me that I will not be getting my son back. How do I prevent them from taking him out of New Zealand, also to send him back to Sydney? It's hard for me to go to New Zealand as I have four other kids to take care of and I am also a single mother. What steps and action would I need to take under family law? Can someone please advise me urgently as I don't have much time...
