C.R.S. § 15-12-1008

If, after an estate has been settled and the personal representative discharged or after one year after a closing statement has been filed, it is determined that the estate has not been fully administered or fully distributed by reason of subsequently discovered property or for any other reason, the court, upon petition of any interested person, and upon notice as it directs, may appoint the same or a successor personal representative to complete the administration or distribution of the estate. If a new appointment is made, unless the court orders otherwise, the provisions of this code apply as appropriate; but no claim previously barred may be asserted in the subsequent administration.
