My ex and I have a temporary custody order of our 12 year old son. This was done last year because my son wanted to spend more time at my house. Now both her and I agree that it is not working out for the best interest of him now. He constantly cries and is upset all the time and wants it changed to the way it was before the custody order. I thought it was because his mom or someone in her family was telling him to do this but he says that is not the case. What do I have to do to get it changed and can it be done without an attorney?
