As of 1893, it was mandatory state law that all vital records had to be filed with the clerks in the corresponding townships. The law only lasted for two years, at first. However, even though it was repealed in 1895, it became the law again in 1899.
In 1923, the North Dakota State Department of Vital Records was opened. Any death and birth records that were recorded before then were required to be transferred to the State Department of Vital Records at that time. The North Dakota Department of Health, Division of Vital Records currently holds all death and birth records that were recorded from July 1, 1893 onward. Those records can be obtained through their website, but the researcher must be able to probe their relationship to the person of interest in order to access the information.
Marriage licenses were generally recorded by each county from the time that the county in question came into being. Those records can be found by contacting the county judge’s office in the county where the marriage is believed to have occurred. The Bismarck Division of Vital Records has some marriage records on file, but only records that were filed after July 1, 1925. Each county’s district court clerk’s office recorded divorce records for that county.
The State Historical Society Reading Room at the Heritage Center hold indexes to recent divorces in the state, marriages from 1925 to the present day, and deaths from around 1900 to the present day.
