Reaffirmation is when borrowers agree to take accountability for debt in order to keep the property that secures the loan (collateral). You and the lender sign a new reaffirmation agreement, which is normally on the same terms as the old one, and file it with the bankruptcy court. Basically, when you reaffirm a debt, you commit to paying it even after your bankruptcy case is over. The creditor’s lien on your property and your responsibility for your debt will generally survive your bankruptcy proceeding.
