No action is required. Your discharge wiped out the underying debt, and there was no final judgment at the time you filed for bankruptcy. Confirm this with your bankruptcy attorney, but otherwise smile and quietly get on with your new life.
Once you filed bankrutcy, the state trial court had no jurisdiction/authority to do anything. The discharge means that the creditor cannot now reopen the action. Forget about it. Sure that you have much better things to occupy your time.
The above is not intended as legal advice. The response does not constitute the creation of an attorney client relationship as this forum does not provide for a confidential communication.
If there was a final judgment entered before your bankruptcy was filed, and if the judgment was in the Circuit Court of the county in which your real property is located, you would want to vacate the judgment or otherwise try to avoid the lien as a preference. If you don't own real property, or if the judgment was in District Court and no notice of lien is filed the judgment is a nullity and no action is needed. If the bankruptcy has closed there is no stay of your action in the case and you can pursue the motion to vacate.
