Reaffirmation Agreements?

Our former BK attorney will not return our calls. BK already discharged a year ago. Here's the problem and a little history. Husband has a motorcycle and husband refused to let it go, I would not sign the reaffirmation agreement, husband did not sign one, attorney even tried to get him to give it up and Harley Davidson Financial said they won't require an affirmation. Husband very stubborn and has mental health issues so he does not see things clearly. He still has the motorcycle but now he has no way to pay for it. He has not ridden the motorcycle for 2 years.

My understanding is that if you did not reaffirm and then if you later for some reason you can not afford the vehicle after the discharge then turn it in, they cannot come after you for the difference because no reaffirmation was signed. Can someone with knowledge help explain if I am right. Please no judgments, we tried exhaustively to get my husband to return the motorcycle before Bk discharge. Can anyone offer info here?
