Individuals may represent themselves in bankruptcy court. However, filing without an attorney or "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 be 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.
