California Law
Who Can Serve Process in California
Governed by California Code of Civil Procedure §§413.10–417.40 and B&P Code §22350.

Under Cal. Code Civ. Proc. §414.10, any person at least 18 years old who is not a party to the action may serve process in California. However, Business & Professions Code §22350 requires that anyone who serves more than 10 papers per calendar year for compensation must be a Registered Process Server (RPS) — registered with the county clerk where the server resides or maintains a principal place of business, bonded, and fingerprinted. Served 123 LLC coordinates exclusively with RPS-registered servers across all 58 counties.

Personal service is the default under §415.10. If personal service cannot be made with reasonable diligence, substituted service may be made under §415.20(b) by leaving a copy at the person's dwelling, usual place of abode, usual place of business, or usual mailing address (other than a P.O. box) in the presence of a competent household member or person apparently in charge at least 18 years old — and thereafter mailing a copy to the same address. Service on entities is governed by §§416.10–416.90, and service by publication requires a court order under §415.50.

Key statute to know: California's "reasonable diligence" requirement before substituted service is enforced strictly. Courts expect documented attempts at different times and days — typically at least three attempts before moving to substituted service. Proof of service on Judicial Council Form POS-010 must include the server's RPS registration number and county. Every proof we file follows the Judicial Council form. Cal. CCP §§414.10, 415.10, 415.20, 415.50, 417.10, 417.20; B&P Code §22350

What this means for your case

An unregistered or out-of-county server in California is a motion-to-quash magnet. California Superior Courts regularly strike service where the RPS wasn't registered in the correct county, where "reasonable diligence" isn't documented before substituted service, or where the POS-010 proof of service is missing the RPS number. Served 123 LLC's servers are RPS-registered and every proof uses the correct Judicial Council form.

FAQ
California Service of Process — Common Questions
Answered under the California Code of Civil Procedure. This is practical guidance, not legal advice.
Who can legally serve process in California?
Under Cal. CCP §414.10, any person at least 18 years old and not a party may serve process. But under B&P Code §22350, anyone who serves more than 10 papers per calendar year for compensation must be a Registered Process Server, registered with the county clerk and bonded.
What California statute governs service of process?
California Code of Civil Procedure §§413.10 through 417.40. §415.10 covers personal service, §415.20 covers substituted service, §415.30 covers notice-and-acknowledgment mail service, §§416.10–416.90 cover entity service, and §415.50 covers publication.
What is substituted service in California?
Under §415.20(b), if personal service cannot be made with reasonable diligence, substituted service may be made by leaving a copy at the person's dwelling, usual place of abode, usual place of business, or usual mailing address (other than a P.O. box) in the presence of a competent household member or person apparently in charge who is at least 18 years old, and thereafter mailing a copy to the same address.
Do you serve in all 58 California counties?
Yes. Served 123 LLC's California network covers every one of the 58 counties — from Del Norte at the Oregon border to San Diego and Imperial at the Mexican border. Hub counties (Los Angeles, Orange, San Diego, San Francisco, Santa Clara, Alameda, San Bernardino, Riverside, Sacramento) offer same-day rush capacity.
What must a California Proof of Service include?
Under Cal. CCP §417.10, the proof of service must include the date, time, place, and manner of service; the identity of the person served; the server's name, address, telephone number; and — if applicable — the Registered Process Server's county of registration and RPS number. Judicial Council Form POS-010 is the approved proof of personal service.
How many attempts before substituted service in California?
There is no hard-coded number, but California courts generally expect at least three documented attempts at varying days and times to establish "reasonable diligence" before moving to substituted service under §415.20(b). Our standard protocol is three GPS-timestamped attempts before substitution.
How fast can Served 123 LLC complete California service?
Same-day service is available when we receive the request before 11:00 AM local time, with strongest coverage in Los Angeles, Orange, San Diego, San Francisco, Santa Clara, Alameda, San Bernardino, Riverside, and Sacramento Counties. Next-day priority service is available statewide.
Do you serve out-of-state subpoenas in California?
Yes. California has adopted the Uniform Interstate Depositions and Discovery Act (UIDDA) at CCP §§2029.100–2029.900. We handle clerk intake, California subpoena issuance, and service on your witness. See our California subpoena domestication page for the full process.
