Colo. Rev. Stat. § 31-12-410
If any actions, suits, or proceedings are pending against any one of the cities or towns at the time of the consolidation, the consolidated city or town shall be substituted as plaintiff or defendant in such action, suit, or proceeding. The same shall thenceforth proceed as if the claim, right, debt, or demand upon which said action, suit, or proceeding was founded had originally existed in favor of or against such consolidated town or city. In like manner, any person who, at the date of consolidation, has any claim, demand, or right of action against any one or more of the cities or towns so consolidating may bring any action, suit, or proceeding necessary for the collection or enforcement thereof after such consolidation against the consolidated city or town in the same manner as though the claim, demand, or right of action had originally existed against such consolidated city or town. In no case shall any tax be levied upon or liability incurred by any property or persons on account of such actions, suits, proceedings, debts, liabilities, or rights of action, except those persons and property which would have been liable for the same in case no consolidation had taken place. The governing body of the consolidated city or town has the power to levy a special tax upon persons and property within the former limits of the city or town against which such action, suit, proceeding, claim, demand, or right of action existed for the payment, liquidation, or settlement thereof or of any judgment founded thereon. The terms of consolidation may make other provisions for the payment of such demands, liabilities, and judgments.
