Colo. Rev. Stat. § 39-3-134
In all cases where an entire property, or a portion of any parcel, tract, or lot of real property, is likely to become exempt from the levy and collection of property tax through exercise of the power of eminent domain, the treasurer shall be joined as a party respondent in any such eminent domain action, and, upon joinder and notice of the proceedings, the treasurer shall assert a claim for the amount of any prorated property taxes for the current taxable year on such property, and all other unpaid property taxes, delinquent interest, or charges thereon, with the clerk of the court in which the proceedings are filed. Upon institution of any such proceedings, the lien of property taxes levied and to be levied shall be transferred from the real property acquired or sought to be acquired to any money awarded or to be awarded for the taking of such real property. Nothing in this section shall require any treasurer to file a claim in any such proceedings involving acquisition of only a portion of any real property if the treasurer is satisfied that there is sufficient taxable real property remaining after the taking of such portion to satisfy any lien for the amount of property taxes payable on such portion taken.
C.R.S. § 39-3-134
