When filing bankruptcy you have to list all assets and debts.  Some are dischargeable in bankruptcy, some are not.
Debts that you can discharge in a bankruptcy generally are:
- credit cards
- personal loans
- bank loans
Debts that you can not normally discharge with a bankruptcy:
- most taxes
- child support
- alimony
- student loans
Also, some debts that are not dischargeable in a chapter 7 bankruptcy can be dischargeable in a chapter 13.
