I am a Co-Signor on a Secured Loan ... is it included in my bankruptcy?

No.  This question is most commonly asked by parents who have co-signed for a vehicle for a child.   An item you co-signed for is not a part of the bankruptcy, unless the primary account holder also initiates a bankruptcy attention.   Although it is not included in the bankruptcy as an item for a discharge, it must be listed as part of the debtor's loans.   The bankruptcy court and trustee must be made aware that the debtor has co-signed for this loan prior to the bankruptcy filing.
