This is a common error that can negatively impact your credit score. You should file a written dispute with each of the three major credit bureaus (Equifax, Experian, and TransUnion). Your dispute letter should clearly identify the account, state that it was discharged in your Chapter 7 bankruptcy (include the case number and discharge date), and demand that the information be corrected to show a $0 balance and indicate the debt was discharged. You should also enclose a copy of your bankruptcy discharge order as proof. The Kugel Law Firm can assist you in preparing and sending these dispute letters.
