first, did the courts agree with your rejection of the petition?
then, it was the attorney, not the administrator that was the problem. As such, it would be unfair to deny the admin the right to their fair compensation due to the attorneys position. That would cause the original date to be used for the filing IMO.
chronology
from date of death;
when was probate opened
when did you become admin
when did the former admin petition for payment
was the attorney that filed the petition still the attorney for the estate at the time the petition was filed
when did you reject payment
when did you inform them the reason for the rejection
Is it really that difficult to get an answer on this matter,you don't know the whole story,
you do realize that due to the second part of that statement, the first part is true
