Registrar of Deeds

The Office of Registrar of Deeds is vitally important to the ownership of real properties within Oklahoma County. All legal instruments, including plat maps, deeds, mortgages, oil and gas leases, tax liens, and military discharge papers, filed with the County by private citizens and public officials are preserved by the County Clerk. It had, as its inception, a date long prior to the Act of Statehood of Oklahoma. Complete written records are kept of all real estate transactions within the County of Oklahoma from its first Patents, as granted by the United States Government; on through the Territorial Days and until the present time. Previously, the office of Registrar of Deeds was an elective office of the County; but, by Legislative Act, the office was combined with that of County Clerk, who is now the Ex-Officio Registrar of Deeds and is charged with the duties and functions of this office, which include maintaining the following:

An accurate and up to the minute record on every piece of property; and all mortgages, oil and gas and other mineral leases on every foot of land in Oklahoma County, as well as all plats of developments or developed areas.
A record of all military discharges presented for filing by the members of the Armed Forces of the United States. This service is free.
All City Charters are filed in this office; also Powers of Attorney, Trust Agreements, Final Decrees, and Divorce Decrees when real estate is involved.
