Bankruptcy Laws

I never filed a bankruptcy nor very knowledgeable in it.  I understand what bankruptcy is but  not really familiar with  certain laws about it.  It  is my understanding that every state has it's own laws regarding the  issue.  Say for instance, West Virginia might be   of different compared to the north carolina bankruptcy laws or Ohio or any other state.  Nevertheless, it is always important that when you are filing a bankruptcy, you understand exactly what you are doing coz if not, it is a wise decision to  hire a professional that could help you along the way.
