You can represent yourself in a bankruptcy case. It is not required that you have an attorney when you file. There are some issues that you can run into though, if you're not represented. You may not have chosen your exemptions properly. You may have left some assets unprotected. A Chapter 7 trustee is not your friend in a bankruptcy case. They are not going to advise you of ways to protect your assets. What happens usually in that situation is the client will come to an attorney after the fact and end up spending a lot more money to undo the mess that they got themselves in.
