I'm afraid I agree with John. Bankruptcy does not generally aleviate liens.

Will a bankruptcy filing absolve all debts?

No. Certain obligations will remain after a filing, such as child support payments for individuals. Nor does bankruptcy eliminate liens on property. It is yet another reason to consider bankruptcy carefully.

Lien: a creditor’s legal claim on assets or property secured by a debt. A bankruptcy will not necessarily eliminate a lien without a court invoking or initiating certain procedures
