I have my first custody hearing at the end of the month and amongst other things I'll be requesting to prevent my son's aunt's boyfriend from being in contact with my son.

Last month I was granted a restraining order against him because of threats of violence he made toward me after voicing concerns I had about him and my son's relationship to my son's mother. The preliminary PO was for me and my son but at the permenant PO hearing it was only granted for me due to my son's mother not contesting him being around our son and I was told if I wanted to prevent contact I would have to do it at our custody hearing.

My question is do I just ask the judge to limit contact with my son from him and explain why I feel it's in my sons best interest?
