My question involves bankruptcy in the state of: Kansas.

My wife and I filed Chapter 7 bankruptcy last year and received a discharge. The trustee has deemed our case a no asset case. On May 6th, our case was officially closed within the bankruptcy court. Sounds pretty simple huh? Well, it's not quite that cut and dry. My mother passed away within the 180 days of our filing. I received an inheritance. I notified my lawyer via email, who in turn notified the trustee. The trustee made the mistake of listing the case as a no asset case even though there are assets that could be dispersed to our creditors. Our lawyer noticed the mistake and actually contacted the trustee to tell him, but it was after the May 6th closing of the case. My question is this: Because the case was closed, can we avoid giving any of my inheritance over to the trustee? Or does the trustee have the authority to essentially go in and "change his mind" or correct his mistake? Thank you for your time!
