I cannot find anywhere, what the actual laws and restrictions for a sex offender are. I am currently the fiance of a now convicted sex offender, he was sentenced this September 2013, and will be home from the DOC in January. But I want to be prepared to know what he is and is not allowed to do. Also, do all the restrictions apply to every sex offender? Thanks.
