In order to get a marriage, divorce, birth, or death record, you will need to contact the state health department or a local vital records office. Sometimes, you can get these records by visiting your county courthouse. In addition to these departments, genealogy clubs, state archives, or historical societies, in some instances, have documents as well. There are typically limitations as to who may gain access to a working Oklahoma vital record document. This is done to shield the privacy of people and prevent ID theft.
