You may get your license at any county office in Colorado for a wedding anywhere in the state. No waiting period. Bring $30 cash plus divorce papers (if applicable). You must get married within 30 days of obtaining the license or it expires. Call the county office nearest you for more details. Please bring your marriage license to the wedding. Your officiant will fill out the bottom part of the license and send it in for you to be recorded with the county. The county will then return the license to you. In the meantime, you may use a marriage certificate provided by your officiant to show proof of marriage. In order to change your name on your driver’s license and other documents, you will need the actual marriage license (or a certified copy).
