3. (3) After notice is given in a proceeding for a guardianship, conservatorship, or protective arrangement under Article 5 of this chapter and until termination of the proceeding, the court in which the petition is filed has:

   1. (a) Exclusive jurisdiction to determine the need for the guardianship, conservatorship, or protective arrangement;
   2. (b) Exclusive jurisdiction to determine how property of the respondent must be managed, expended, or distributed to or for the use of the respondent, an individual who is dependent in fact on the respondent, or other claimant;
   3. (c) Nonexclusive jurisdiction to determine the validity of a claim against the respondent or property of the respondent or a question of title concerning the property; and
   4. (d) If a guardian or conservator is appointed, exclusive jurisdiction over issues related to administration of the guardianship or conservatorship.
4. (4) A court that appoints a guardian or conservator, or authorizes a protective arrangement under Article 5 of this chapter, has exclusive and continuing jurisdiction over the proceeding until the court terminates the proceeding or the appointment or protective arrangement expires by its terms.
