I'm in Dubuque Ia and she is going to Elmhurst (Chicago) IL. I don't want to get in a big custody fight and I am agreeable to her having him live with her, I just want to make sure that she doesn't screw me down the road and keep him from me. I want to be able to see my child at least every other weekend and switching holidays. My son is 2.5 years old so school isn't an issue yet. Would we be alight with just a writen agreement getting everything down on paper for now and having it noterized?
