California Federal Districts: Four Courts, Appeals, and Filing

California has four federal district courts: the Northern, Eastern, Central, and Southern Districts of California. Which one hears your case depends on the county where the dispute arose or where the parties live, and each district has its own courthouses, local rules, and separate attorney admission process. These courts handle cases involving federal law, constitutional questions, and disputes between citizens of different states when more than $75,000 is at stake.¹

Northern District of California

The Northern District runs along the coast from Monterey County to the Oregon border and covers fifteen counties: Alameda, Contra Costa, Del Norte, Humboldt, Lake, Marin, Mendocino, Monterey, Napa, San Benito, San Francisco, San Mateo, Santa Clara, Santa Cruz, and Sonoma.² That takes in the San Francisco Bay Area, Silicon Valley, and the rural north coast.

Federal statute designates four places where court is held: San Francisco, Oakland, San Jose, and Eureka.² The “Eureka” courthouse is physically located in nearby McKinleyville.³ San Francisco and Oakland handle most of the caseload, with San Jose serving the Santa Clara Valley and points south.⁴

For case-assignment purposes the court groups San Francisco and Oakland together, while San Jose and Eureka each operate under their own divisional rules. A complaint filed here must state the basis for the divisional assignment so the clerk can route it to the right courthouse.⁵

Eastern District of California

The Eastern District is geographically enormous, running from the Oregon border south through the Central Valley and Sierra Nevada to the Tehachapi Mountains. It covers thirty-four counties, including Sacramento, Fresno, San Joaquin, Kern, and Solano, along with sparsely populated mountain counties like Alpine, Mono, and Inyo.² By land area it is one of the largest federal districts in the lower 48 states.

Statute designates four cities where court is held: Sacramento, Fresno, Redding, and Bakersfield.² The court also maintains a small courthouse in Yosemite, though filings for cases there must be submitted electronically or through the Fresno clerk’s office.⁶ The caseload reflects the region: water rights, environmental regulation, federal land management, and agricultural disputes appear frequently alongside the criminal and civil matters any federal court handles.

Central District of California

The Central District is the most populous federal judicial district in the country, serving more than 19 million people across seven counties.² It is split into three divisions, each with its own courthouse and assigned counties:

Western Division (Los Angeles): Los Angeles, San Luis Obispo, Santa Barbara, and Ventura counties.
Southern Division (Santa Ana): Orange County.
Eastern Division (Riverside): Riverside and San Bernardino counties.

This breakdown comes directly from the statute and determines where your case is heard.² The Western Division in downtown Los Angeles takes the largest share of filings, including entertainment, intellectual property, and complex commercial litigation. Riverside serves the Inland Empire, and Santa Ana covers Orange County.⁷

Each division maintains its own clerk’s office and courtrooms. Filing in the wrong division does not end the case, but the court can transfer it and that adds delay.

Southern District of California

The Southern District is the smallest of the four by geography, covering just two counties: San Diego and Imperial.² Its position along the international border with Mexico produces one of the heaviest criminal dockets in the federal system; immigration offenses accounted for 41% of all criminal cases sentenced in the district in fiscal year 2024.⁸

The main courthouse sits in downtown San Diego, with a second courthouse in El Centro serving Imperial County.⁹ Congress has authorized 13 active district judgeships for the court, and weighted caseloads per judge have consistently run above the national average.¹⁰

Where Appeals Go

All four California federal districts sit within the United States Court of Appeals for the Ninth Circuit, the largest federal appellate circuit in the country.¹¹ If you lose at trial in any California federal district court, your appeal goes to the Ninth Circuit, which is headquartered in San Francisco. Ninth Circuit rulings are binding on every district court within its territory, so a decision in a case from the Eastern District carries the same weight in the Northern, Central, and Southern Districts. Only the U.S. Supreme Court can override a Ninth Circuit ruling.

Filing a Case in a California Federal Court

Filing Fees and Fee Waivers

Starting a civil case in any federal district court costs $405. That total consists of a $350 statutory filing fee plus a $55 administrative fee set by the Judicial Conference.¹² If you cannot afford the fee, you can apply to proceed in forma pauperis by filing an affidavit detailing your income and assets. The court will waive the fee if it finds you genuinely unable to pay.¹³

Electronic Filing

Attorneys in California federal courts must file documents electronically through CM/ECF, the federal judiciary’s online case management system. If you are representing yourself, the rules are more forgiving. Most districts allow self-represented litigants to file on paper, and several California districts now offer electronic submission portals designed for pro se filers.

Local Rules

Each California district maintains its own set of local rules that supplement the Federal Rules of Civil Procedure. Local rules cover page limits for briefs, formatting requirements, how cases get assigned to judges, and scheduling procedures. Federal law requires local rules to be consistent with the federal rules and not duplicate them.¹⁴ The differences between districts are real. The Northern District’s rules on case assignment look nothing like the Central District’s divisional system. If you are moving from one California federal court to another, read the local rules before filing; that is where most avoidable procedural mistakes happen.

Attorney Admission

Membership in the California State Bar does not automatically let you practice in California’s federal courts. Each district requires a separate admission process that involves submitting an application, providing a certificate of good standing from the state bar, paying an admission fee, and taking an oath. Admission fees vary by district; the Central District, for example, charges between $231 and $281 depending on how long the attorney has been licensed.¹⁵ Admission to one California federal district does not grant admission to the others. An attorney admitted in the Northern District still needs separate admission to practice in the Central District.

Help for Self-Represented Litigants

If you are filing a federal case without a lawyer, several California districts offer free pro se clinics. The Central District runs clinics in Los Angeles, Riverside, and Santa Ana, staffed by the nonprofit law firm Public Counsel. The Los Angeles clinic accepts walk-ins on Wednesdays and can be reached at 213-385-2977 for appointments.¹⁶ These clinics do not represent you, but they can help you understand filing procedures, court forms, and how to navigate the federal system on your own.
