Hi. My wife separated 12 months ago from me. We have both lived in central west NSW most our lives - over 12 years for her, me all my life. Both our families live in same town. Parents and siblings. Since our separation, my wife has already started a new relationship 2 months ago with a man in Sydney, approximately 4 hrs drive from where we live. We have 3 children the eldest is already at school here. She wants to move our children from their life here in central west to Sydney. Where do I stand legally to prevent this happening ( custody of children)?
