Arizona County records differ extensively from county to county in either quality and quantity. Some have been very carefully maintained while others have been substantially mistreated and mistreated. A certain amount of Arizona records have merely disappeared. For genealogists carrying out research in Arizona there’s no valuable replace for an on-site research of county courthouse records. For Definitions of all court terms see the Genealogy Encyclopedia
Arizona CountiesArizona is divided into 15 counties. Four counties (Mohave, Pima, Yavapai and Yuma) were created in 1864 following the organization of the Arizona Territory in 1862. All but La Paz County were created by the time Arizona was granted statehood in 1912. The County names: 8 of them named for Native American Tribes, 2 of them for People, 2 of them for Mountains, 2 of them for Rivers, and 1 of them for a Town.
Each county in Arizona has a count seat located in a certain city within that county. However, sometimes the county seat has moved from one city to another. That information is historically important in order to determine migration information. The counties pages below report all dates of court holdings, probate proceedings, and land-related cases. Sometimes later records may contain earlier records.
Territorial court cases, mining claims, and grant records for Arizona may pre-date the formation of counties. Therefore, researchers should be careful when looking for such information. See also a list of links to county and county seat government run websites.
Sometimes a city that was not actually the county seat would serve as one for a time period. However, they do not carry the records. The Arizona State Archives catalogue earlier dates for some of the records. These are usually migrated to the official offices, and sometimes earlier and later records are mixed. Contact the county recorder’s office at the county seat’s address for land records. The superior court clerk for the county handles records for marriages, divorces, and probate.
Because of mining claims, grants, and territorial court cases, many Arizona records have dates from before the county formation.

List of Arizona Extinct Counties
Arizona seems to have counties that no longer are in existence. They were set up by the state, provincial, or territorial governing administration. Most of these counties were established and disbanded in the 19th century; county borders have changed little since 1900 in the great majority of states. These counties really should be investigated when you are performing genealogy research. Pay close attention where the courthouse records went to if the county was abolished or joined with some other county.
- Pah-Ute County – is a former county in the northwest corner of Arizona Territory, created from the division of the existing Mohave County on December 22, 1865. Much of Pah-Ute County was in the small triangular section of what is now the southern part of the U.S. state of Nevada. The county seat was the town of Callville, which is now occupied by a part of Lake Mead. Pah-Ute was the historical spelling of the Indian tribe that is today referred to as the Paiute. A short time later, on May 5, 1866, all of Pah-Ute County west of the Colorado River and west of 114 degrees latitude became part of the new state of Nevada, over the protest of the territory of Arizona. The remaining portion of Pah-Ute County in Arizona was so underpopulated that no viable county government could be formed, and on February 18, 1871, the remainder of Pah-Ute County was absorbed back into Mohave County. Most of modern Clark County, Nevada, was once Pah-Ute County, Arizona, including Nevada’s largest and most famous city, Las Vegas. To this day, some textbooks still refer to the Pah-Ute as Arizona’s “Lost County”.
