Legal fees are often like any other dischargeable debt. The lawyer may file a claim in your case if significant work has been done. Sure, you can try to do it yourself. The chances of making a serious mistake are pretty high, and we see the questions here from people who try.

There is no law requiring an attorney to file bankruptcy petition for you. However I would strongly suggest that you consider an experienced attorney in your area.
