the court, on petition by any person or on its own motion, may appoint a temporary guardian for the incapacitated person or minor for a specified period not to exceed ninety (90) days. Upon notice and hearing, the court may, with good cause shown, grant one (1) extension of the temporary guardianship for not more than ninety (90) days. No such appointment shall be made except after notice and hearing unless it is alleged and found by the court that immediate and irreparable injury to the person or injury, loss, or damage to the property of the alleged incapacitated person or minor may result before the alleged incapacitated person or minor can be heard in response to the petition. If a temporary guardian is appointed without advance notice and the alleged incapacitated person or minor files a petition that the guardianship be terminated or the court order modified, the court shall hear and determine the petition at the earliest possible time.
the petitioner shall, on the earlier of the date the court enters an order scheduling a hearing on the petition or the date the court enters an order appointing a temporary guardian, serve complete copies of the petition, the court's order, and the notice required by IC 29-3-6-2 on every person entitled to receive notice under IC 29-3-6-1(a) and on each additional person to whom the court directs that notice be given. The requirements of this subsection are in addition to the petitioner's obligations under Rule 65 of the Indiana Rules of Trial Procedure to make a specific showing of the petitioner's efforts to provide advance notice to all interested persons or the reasons why advance notice cannot or should not be given.
