The purpose of filing for Bankruptcy is to preclude your creditors from pursuing you in collections. So it is your burden to ensure that all of your liabilities are disclosed on your Petition when the case is filed with the Court.  Specifically, you must identify each company to whom you owe money, the approximate balance due, their mailing address and (if known) the account number.

Therefore, unless these obligations are detailed as required, you could potentially find yourself subject to lawsuits, garnishments, and/or other collections activities despite having sought Bankruptcy protection.
