The state of Montana did not require birth records to be kept until 1895. At that time, a law was passed by the Legislative Assembly that gave that responsibility to midwives and physicians. The county clerk in the county where the birth took place holds the birth records that were recorded before 1907. Both births and deaths were recorded by the state, beginning in 1907. However, the mandatory birth registration wasn’t well-enforced until 1915. Around 90% of all births were being routinely registered, as of 1922.
Both births and deaths were included in the law passed in 1895. Undertakers, physicians, sextons, coroners, and clergymen all had the responsibility of recording deaths for which they were present, as of the time that the law was passed. In 1907, deaths started to be recorded by the state. Around 90% of all deaths were registered with the state, as of 1910. However, death registrations were not close to complete on an annual basis until 1915.
The Office of Vital Statistics, Montana Department of Health and Human Services can provide certified copies of death and birth certificates that were recorded after 1907.
The Office of Vital Statistics does not provide records relating to divorces or marriages. However, those records can be found at the district court clerk’s office in the county where the divorce or marriage was originally recorded. Starting in July of 1943, divorces were registered with the state of Montana. Copies of marriage certificates from the various counties can be viewed at the Salt Lake City Family History Library (FHL). Those copies have been placed on microfilm.
