Individuals may represent themselves in bankruptcy court. However, filing without an attorney (referred to as "pro se") is extremely difficult to do successfully.  

Corporations and partnerships must have an attorney to file a bankruptcy case.

It is very important that a bankruptcy case is filed and handled correctly. The rules are very technical, and a misstep may affect a debtor's rights. All parties must comply with the Federal Rules of Bankruptcy Procedure, the Bankruptcy Code Federal (National) Rules, as well as this court's Local Rules. For example, a debtor whose case is dismissed for failure to file a required document (such as a credit counseling certificate) may lose the right to file another case or lose protections in a later case, including the benefit of the automatic stay.

Bankruptcy has long-term financial and legal consequences - hiring a competent attorney is strongly recommended.
