I moved 6 months ago from South Dakota and Florida with my 4 yrs old son. I got a divorce 2 years ago and there isnt anything in our divorce papers that states that i cant move out of state with my son. My ex-husband didnt have any problem with the move. Now that summer time is coming up we is demanding my son to go back to SD for 2 months, without any prior agreements before the move, but to have it on my expense. What can I do, to make an agreement with him, before I have to take legal actions
