Arizona Court Records

Arizona’s has a common organization to its judicial system. Courts are heard locally and then move with complexity to larger and further removed jurisdiction. Civil and small claims come before the Justice of the Peace, while town and city violations go to municipal court. The court calendar and records in each county are maintained by a clerk of the superior courts. The superior courts hear appeals from the lower courts and civil and criminal cases, including divorces. The Supreme Court functions statewide and hears Extraordinary writs and appeals from the court of appeals in Phoenix and Tucson are heard by the Supreme Court. Writs and appeals from the county superior courts are also handled there. Many county court records are on microfilm at the FHL.

Arizona Land Records

The area of present-day Arizona began as a Spanish territory, reverting to Mexico on its independence from Spain. Much of the land was purchased by the United States after the Mexican War, making it part of the New Mexico Territory in 1850. Arizona separated became its own official territory on February 24, 1863. The region of Pah-Ute County was ceded to Nevada in 1866. However, the population and settlement of Arizona was still relatively slow, primarily developing in the Tucson area. Several Native American peoples occupied the area, causing continuous wars that did not end until 1886. This heavy conflict was one of the deterrents to the expansion of Arizona’s frontier.

To research lands that were granted to the United States in 1848 and for private land claims, you can write to the National Archives—Southwest Region. Unfortunately fraudulent land claims were relatively abundant until the late 1800s, when U.S. authorities authenticated private land claims. These private land registers were transferred to the National Archives—Southwest Region, in 1960. Lands from the Gadsden Purchase can be researched at the Pima County Recorder’s Office at Tucson.

The year of Arizona’s admittance as a territory in 1863 was the same year that the U.S. Federal District Land Office opened. Land could be acquired directly from the federal government, making Arizona a public-domain state. Land offices that opened in Prescott in 1863 and Florence and Gila in 1873 moved to Tucson in 1881 and Phoenix in 1905. All offices were eventually replaced by the land office in Phoenix.

Early land claims consist mainly of mining enterprises. Consult the BLM Arizona State Office for patents, copies of tract books, and plat maps. The National Archives—Southwest Region should be included in any research on early land records in Arizona. You will find abundant resources there, including mining and homestead surveys, land claims, grazing service records, and rights-of-way claims and settlements for Gila, Salt River, and Navajo Meridians. There are also land entry case files at the National Archives—Rocky Mountain Region. Include the person’s name and state of Arizona in any correspondence. Arizona records before to 1908 have been indexed alphabetically, so you should also include whether or not your inquiry is for a date prior to 1908.

You can request land records from the county recorder, as this is where jurisdiction for county land transactions was held. It will help to understand what to expect as a result of how ownership was acquired in the state. Because Arizona was previously part of the New Mexico Territory, where pueblos had already been established, the federal government recognized the majority of prior claims. Therefore, it is common to read units of measurement represented by Spanish phrases such as “leagues” and “varas.” Most county land records in Arizona are on microfilm at the FHL.

Arizona Probate Records

Proceedings concerning a person’s death, adoption, or guardianship are recorded by the probate courts. These are rich sources of genealogy data and can help you reconcile problems or inconsistencies with family relationships in your research. You can find these records in the offices of the clerk of the Supreme Court.

Whether a written last will and testament was prepared (testate case) or no will was written (intestate), the proceedings would have been heard in the county of residence or where property was held. If minor heirs are involved, you will find additional records in the files. Their names may appear in court records for as long as they remained minors. You should closely examine all indexes and related cases and court records to make sure you have the complete information on a probate file. Probate records for many counties are microfilmed at the FHL. See Also Guide to U.S. Probate Records Research

Some records hold multiple consecutive years while others are for a single tax year. There is a printed guide available, listed in Archives, Libraries, and Societies.
