Official recording of marriage records in Colorado was not required until 1881. There are records of marriages much earlier than 1881, but this varies by county. Some of the early marriages in
Colorado were written down by the officiate on whatever was handy. One county has some original early marriages recorded on 3" x 3" pieces of paper.
The basic info found on an early Colorado marriage record is the marriage date, county where the wedding took place, name of groom, name of bride, and the officiate, such as a minister or justice
of the peace.
After 1881 a couple wanting to marry purchased a marriage license from the county clerk. These applications include the bride and groom's age and birthdates, residence and parents names, previous
marriages, divorce status, and names of witnesses.
Unlike other Colorado vital records, which can be obtained from County Vital Records Offices, marriage records are maintained by county clerks. For official copies of Colorado marriage
certificates, contact the county clerk where the license was issued. Early Colorado marriage records are public records.
Colorado County Clerks have marriages starting at these dates. I haven't checked all counties, but am assuming that records exist from at least the date of county formation. Check with the county
of interest to see what records they have and fees associated with ordering copies of records.
