If your case has been discharged but has not actually been closed, you might file a 'motion to redeem' for $10.00 and include a proposed order with it to put them on the defensive. Then if they don't respond the judge can issue the order and you will have a court order that says you can pay $10.00 to the lien holder and the court will then order they transfer clear title to you.

If you don't want to do that, then send a letter, via certified mail return receipt requested, to the attorney for the bank/lender/lienholder telling them that they need to either take possession of the car or give you clean title to the car so you can dispose of it. That was what was used in 'In Re Pratt' against GMAC. When GMAC did not do either, Pratt's attorney filed a motion for sanctions for violating the bankruptcy discharge. It was upheld in the 1st circuit court of appeals (Main, New Hampshire, Massachusetts, Rhode Island) which makes it a persuasive decision in other circuits.
