From Illinois. Ex-wife has been leaving my 8 year old son home alone. He has told me this but of course I have no proof because it has happened in the past. He informed me that she has instructed him not to answer the phone when I call (they have caller ID) when he is home alone. I view this as not being able to provide the proper care for my son. What is the reality of a judge viewing the same should I return to court to solicit custody based soley on this matter? Do I have other options? I want custody of my son but lost a previous custody battle. In the least, I do not want her to leave him alone, but I selfishly would like to use this as an opportunity to gain custody of my son. Any comments?
