Leaving state with no custody order
I have a 16 month old son with my ex. We were in a 2 1/2 year on and off relationship. We have been broken up once again for about a month. I do have a child support order against him and he doesn't pay child support at all right now. He is soon to be 1700 behind, which is about 4 months of non payment. He keeps telling me that he has "50/50" support with me, which I don't feel is correct. I feel like I have sole custody of my child. He was having visitation every other weekend up until recently when my son almost landed in the hospital because of him. I want to know what his rights really are since there is NO visitation order ordered by the court, and what is my best route to make sure that I can keep my child away from him except for supervised visitation?
