Some secured creditors will require you to sign a Reaffirmation Agreement for your house, car or possibly a purchase money security interest. A Reaffirmation Agreement re-obligates you on the loan. The Creditor and Debtor must sign, and the Judge must approve the Reaffirmation.
The benefits of a Reaffirmation Agreement is that you 1. will be able to keep the property per the original contract, and 2. will be able to receive positive credit history for every payment you make.
It is important to understand that if you fall behind on payments after your Bankruptcy and you signed a Reaffirmation Agreement, the Creditor has the right to sue you in state court for non-payment.
