A reaffirmation agreement is, as I’ve written here before, a separate agreement that you may have the option to sign in a Chapter 7 bankruptcy that, essentially, puts you back on the hook for the “reaffirmed” debt as if you had never filed for bankruptcy at all. A Chapter 7 bankruptcy discharges ALL debts owed (except for those deemed to be non-dischargeable by the US Bankruptcy Code, such as child support arrearages or most tax debts, among others), flat-out, unless a debt is “reaffirmed.”
The reaffirmation agreement is a form document with contractual terms of the loans filled in that is provided by a creditor after filing and which requires the your signature, your attorney’s signature IF there is no “undue hardship” (more on this below), and the creditor’s signature. Once signed, it is provided to the creditor, and it is the creditor’s job to file it with the court. If filed and approved, you will be obliged to pay the debt regardless of the bankruptcy.
In most cases, I do not recommend that my bankruptcy clients here in Michigan sign reaffirmation agreements.
