Colo. Rev. Stat. § 15-12-723
If any personal representative, heir, legatee, creditor, guardian, or conservator or other person interested in the estate of any deceased person or protected person complains to the court, in writing, that any person is suspected to have concealed, embezzled, carried away, or disposed of any money, goods, or chattels of the deceased or protected person, or that such person has in his possession or knowledge any deeds, conveyances, bonds, contracts, or other writings which contain evidence of or tend to disclose the right, title, interest, or claim of the decedent or protected person to any real or personal estate, or any claim or demand, or any last will and testament of the deceased, the said district or probate court may cite such suspected person to appear before it and may examine him on oath upon the matter of such complaint. If the person cited refuses to appear and submit to such examination or to answer such interrogatories as may be put to him touching the matter of such complaint, the court may, by warrant for that purpose, commit him to the county jail until he complies with the order of the court. All such interrogatories and answers may be in writing and signed by the party examined and filed in the district or probate court.
