My ex-wife is trying to move to florida with my son. I live in ohio about two hours away from my son in michigan. She met a man online and has decided to marry him and move to florida. She has only known this man for about 4 months. My son has a medical condition where he has issues with heat and humidity. I have joint legal custody with liberal visitation. She has sole physical custody. I have informed her that I am againiest this move and I she has given me nothing in writing about her knew address and where she has set up medical treatment at. My son's entire family lives within a tree hour radius of each other, this has always ben his support sturcture. My ex has said she will fly him up, but I have nothing in writing. I do not want my son to move, is there anything I can do to prevent this.
