Almost 3 years ago agreed to let my ex husband be the primary parent due to my dad passing away 3 weeks before we had court i thought it would be in the best interest. Now i want them in my care at all time because My children are in a unsanitary/unsafe environment i have pictures. The house is disgusting and the father smokes marijuana. He leaves the kids in the house while he sits in the garage. He drives with them and he has no licence. I have no proof of the smoking marijuana unless they drug test but do you thjnk i have a good chance at winning my case? I have been paying child support and everything else
