(1) When the petition for appointment of a guardian for an incapacitated person is heard upon the conclusion of the hearing in which the person is determined to be incapacitated, the court shall hear the petition without further notice. If the petition is heard on a later date, reasonable notice of the hearing must be served on the incapacitated person, the person’s attorney, if any, any guardian then serving, the person’s next of kin, and such other interested persons as the court may direct.
(2) When a petition for appointment of a guardian for a minor is filed, formal notice must be served on the minor’s parents. If the petitioner has custody of the minor and the petition alleges that, after diligent search, the parents cannot be found, the parents may be served by informal notice, delivered to their last known address or addresses. When a parent petitions for appointment as guardian for his or her minor child, no notice is necessary unless the other parent is living and does not consent to the appointment.
