You need your aunt to determine what her exact role was in the partnership.  If on paper she is merely listed as an investor, there will not be liability on her part. If she is listed even in state records (secretary of state) as a partner, then she needs to obtain an attorney to help her traverse the bankruptcy quagmire (from personal bankruptcy to partnership bankruptcy).  If she can or her attorney can show fraud, perhaps she may not be held liable for any of the partnership's debts.
