If you have a bill and two peoples name are on it and one file for bankruptcy is the other person liable?

Filing bankruptcy only eliminates the obligations of the party filing bankruptcy.  It does not alter the obligations of anyone else.  So, if your brother-in-law was obligated on the debt before you file bankruptcy, then he will be liable on it afterwards. In a Chapter 13 case only, creditors would be prohibited from trying to collect from your brother-in-law due to what is known as the "co-debtor stay" during the time you're in the Chapter 13 case, but would be free to collect from him pursuant to the laws of whatever state controls after your Chapter 13 case is completed (if you did not pay 100% through the Chapter 13).
