At least 20 days before the return day of a final accounting the testamentary trustee shall deliver to each beneficiary a copy of the account and a notice of the time and place at which the account will be presented for approval, which date shall not be earlier than 30 days after the account was filed. Such delivery may be accomplished in the same manner as with regard to the service of papers on the intermediate accounting. The notice shall inform the beneficiaries of the amount of commissions or other compensation to be requested by the trustee on the application for approval of the account, and the amount of other fees which the court will then be requested to allow.
