Colorado Revised Statutes Title 13. Courts and Court Procedure § 13-52-111. Return--endorsement--entry

All executions shall be made returnable ninety days after date, and no writ of execution shall bind the personal property, goods, or chattels of any person against whom such writ is issued until the writ is delivered to the sheriff or other officer for execution. For a better manifestation of the time, the sheriff or other officer, on receipt of every such writ, shall endorse upon the back thereof the hour, day of the month, and the year when the same was received by him and shall immediately enter the receipt of said writ and the time of receiving it in a book to be kept for that purpose at the office of the sheriff. Said book shall be a public record and open to the inspection of the public. The execution shall be returned within ninety days from date of issue, unless sale is pending under levy made.
