Colo. Rev. Stat. § 38-36-153
No new certificates of titles shall be entered, and no memorial shall be made upon any certificate of title in pursuance of any deed or other voluntary instrument unless the owner's duplicate certificate is presented with such instrument, except in cases provided for in this article, or upon the order of the court, for cause shown. Whenever such order is made, a memorial therefor shall be entered, or a new certificate issued, as directed by said order. The production of the owner's duplicate certificate, whenever any voluntary instrument is presented for registration, shall be conclusive authority from the registered owner to the registrar of titles to enter a new certificate or to make a memorial of registration in accordance with such instrument, and a new certificate or memorial shall be binding upon the registered owner and upon all persons claiming under him, in favor of every purchaser for value and in good faith.
