If you have been sued, DO NOT IGNORE IT! Contact a debt collection lawyer immediately. Gather the court summons, any collection letters, statements and correspondence from the creditor, and any other documents or notes you have kept related to the debt. The attorney will need to review these documents.
You want to avoid a judgment being entered against you. Judgments may result in wage, bank, or personal property attachments. If a hearing date is inconvenient, contact the court. You may be able to have it rescheduled.
