California Code, Probate Code - PROB § 10451

(a) If the authority to administer the estate under this part is requested in the petition for appointment of the personal representative, notice of the hearing on the petition shall be given for the period and in the manner applicable to the petition for appointment.

(b) Where proceedings for the administration of the estate are pending at the time a petition is filed under Section 10450, notice of the hearing on the petition shall be given as provided in Section 1220 to all of the following persons:

(c) The notice of hearing of the petition for authority to administer the estate under this part, whether included in the petition for appointment or in a separate petition, shall include the substance of the following statement: “The petition requests authority to administer the estate under the Independent Administration of Estates Act. This will avoid the need to obtain court approval for many actions taken in connection with the estate. However, before taking certain actions, the personal representative will be required to give notice to interested persons unless they have waived notice or have consented to the proposed action. Independent administration authority will be granted unless good cause is shown why it should not be.”
