Colo. Rev. Stat. § 38-42-105
If the owner of such lease neglects or refuses to execute a release as provided by section 38-42-104, then the owner of the leased premises may sue in any court of competent jurisdiction to obtain such release, and he may also recover in such action from the lessee, his successors, or assigns the sum of one hundred dollars as damages and all costs, together with a reasonable attorney's fee for preparing and prosecuting the suit, and he may also recover any additional damages that the evidence in the case warrants. In all such actions, writs of attachment may issue as in other cases if the owner of the leased premises makes demand for release in writing, by certified or registered mail, sent to the last-known address of the lessee, successor, or assignee, as the case may be, at least thirty days prior to instituting an action under this section.
