Generally speaking, the Personal Representative has no personal liability for anything regarding the estate unless the PR in some way caused a problem that resulted in a breach or excess fees to be charged.  The estate is responsible for the attorney fees but I am surprised that this issue was not dealt with from the beginning, unless circumstances changed during probate and unexpected fees resulted.  You - or the PR - needs to discuss this with the attorney as soon as he or she can.  If the estate is insolvent then it can file for bankruptcy as well.  But some one needs to look at all that has transpired to guide you in any way.  Good luck.
