Colorado Revised Statutes Title 13. Courts and Court Procedure § 13-61-104. Garnishee to answer

It is the duty of such officer to answer any garnishee summons served upon him under the provisions of this article in the same manner as is provided by law for the answer of garnishee summons by private corporations. If such answer is accompanied by a certificate of such officer that the same is true, such answer need not be under oath or affirmation, and such officer shall not be required to appear and answer in person, but may file his answer in writing or submit the same by United States mail to the court, or clerk thereof, designated in such summons. The officer need not include as money due the amount of any warrant or check drawn and signed prior to the time of the service of such garnishee summons.
