Legal Question in Wills and Trusts in Georgia

There is no executor at this point (an acknowledgement is done at a time no one is handling the estate yet). And the fact that you were unaware of that is a good reason to call a lawyer to know what happens in probate.

Short answer is that you must acknowledge service of the petition. However, what you decide to do next is up to you. If you wish to object to either probate of the will or the apppointment of the personal representative, then you should consult a probate attorney. Statements of assets, called "inventories" are filed later, after the will has been admitted to probate and after the executor has been appointed. They are filed with the court, not the beneficiaries or heirs.
