In the case of a petition for modification of a guardianship or conservatorship, the court shall order (a) limiting or reducing the powers of the guardian or conservator if the court finds by a preponderance of the evidence that it is in the best interests of the incapacitated person to do so, or (b) increasing or expanding the powers of the guardian or conservator if the court finds by clear and convincing evidence that it is in the best interests of the incapacitated person to do so.
The court may order a new bond or other appropriate relief upon finding by a preponderance of the evidence that the guardian or conservator is not acting in the best interests of the incapacitated person or of the estate.
A guardianship or conservatorship shall terminate upon the death of the incapacitated person or, if ordered by the court, following a hearing on the petition of any interested person.
