You could try but I am not sure that it would be legally binding on the administrators.  They can do as they see fit "in the best interests of the estate" and the law would probably back them up.  What you do have is the right to make sure that they are doing things properly and ask for an accounting of the estate.  Think about it again. ANd make sure you understand all the fees associatied here - as administrators and legal fees.  They will be plentiful. Good luck.
