My husband has a non biological son who is 12 yrs. old his real father is in the picture and the mother is the ex-girlfriend. She is nuts. he was in his life consistantly until we moved in together. she keeps finding reasons to take him from us. she has even attempted to contact chld services and made up this crazy story about me abusing my now husband, anything tat she can do she does. But reguardless my husband still wants to be a part of this kids life. She took away the visitation about two-years ago. now we see him 1 day a week supervised for two hours. All of the sudden she is going to give him to us 1 day every two weeks non supervised. but the problem that I have is with all of the trouble she has caused us I am scared of the non supervised part because who knows what she is going to do. So I told my husband to get her to sign something a permission slip if you will for him to be in our care. I am just wondering if this will help keep us out of trouble. I wouldn't put it past her to try to get us for kidnapping or anything but at the same time I dont want t be the reason that he cant see him what should I do?
