My ex wants to move 200 miles away and wants to take my son. I'm totally against it. Can I do something legally that can prevent her from moving completely? I live in Missouri. I have him at least 50% of the time. He is only 8 so by law he can't make a decision where he wants to live until he's 12. Does anyone have any idea or have personally lived through this that can tell me how this will all unfold if I take her to court?
