The State of Oklahoma Marriage Records are maintained at the County Clerk of Court where the marriage occurred. Oklahoma does not follow what other states do with their public records wherein they have a central repository for them. Fortunately, marriage records are deemed as part of the public domain and any member of the public can place a request for them. Marriage records are the only legal documents accepted by any government body to prove the validity of a marriage. If a marriage record is not yet finalized, a marriage is still considered incomplete.
