Do I have to list all my debts?
Yes. All the debts you owe have to be listed. Everything. There's no legal way to pick and choose. Trying to do so could be a crime.
Do not jump to the conclusion that you will lose property you owe money on! Listing the debt correctly is the first step to assuring you can keep the property you need to keep -- and get rid of the debt you don't need any more.
Even if you don't want to wipe out a debt, like one owed to a friend or relative, or a doctor you want to visit again, they should be listed.
You can always repay discharged debts after the bankruptcy voluntarily. Or you can even reaffirm your legal obligation to debts.
You should even list debts you do not think you owe for some reason. This is your chance to be sure, for good, that you don't.
