Utah Code § 75-3-1008: Subsequent administration.

(1) If other property of the estate is discovered after an estate has been settled and the personal representative discharged or after one year after a closing statement has been filed, the court upon petition of any interested person and upon notice as it directs may appoint the same or a successor personal representative to administer the subsequently-discovered estate.

(2) If a new appointment is made, unless the court orders otherwise, the provisions of this title apply as appropriate but no claim previously barred may be asserted in the subsequent administration.
