If the creditor obtained a judgment prior to your filing bankruptcy, but the creditor did not record the "abstract of judgment" as a lien with the county until after you filed for bankruptcy, then the lien is invalid, because the judgment is unenforceable.
In such a case, you would file a motion for an order to show cause for contempt in bankruptcy could and ask for the court to order damages against the creditor for violating the discharge injunction, and further to order the creditor to record a lien release to clear your property from the cloud on title.
You can also get attorney's fees. So, you can contact a bankruptcy lawyer to handle this for you and get reimbursed from the creditor. Before you do, you could send the creditor a notice, that unless he/she records a lien release immediately, that you will commence legal action to enforce your rights.
Hope this helps.
