In California, any person who is at least 18 years old and is not a party to the lawsuit can serve court papers. That covers a friend, an adult relative, a coworker, a registered professional process server, or a sheriff’s deputy. The one firm limit is neutrality: whoever hands over the summons and complaint cannot be the plaintiff, the defendant, or anyone else named in the case.1California Legislative Information. California Code of Civil Procedure 414.10 – Persons Who May Serve Summons
Within that rule, you have three practical choices. Each one is legal. They differ in cost, speed, and how much protection you get if the other side later claims the papers were never properly delivered.
A Friend, Relative, or Other Adult
The cheapest route is to ask an adult you know to deliver the papers for you. Anyone 18 or older qualifies as long as they have no connection to the case. A neighbor, an adult child, a sibling, a coworker — all fine, as long as they aren’t named in the lawsuit.
This works best when the other party is easy to find and unlikely to make trouble about how the documents were handed over. The savings are real, but so are the risks. If your server gives the papers to the wrong person, leaves them in the wrong spot, or botches the follow-up paperwork, the service can be thrown out and you start over. California also now requires timestamped, GPS-tagged photographs for most in-person service, which an untrained friend may not know to take.
Registered Process Servers
A professional process server runs the delivery as a business. California requires anyone who completes more than 10 paid services in a calendar year to register with the county clerk where they live or run their business. Corporations and partnerships that make money from process serving register on the same terms.2California Legislative Information. California Code of Business and Professions Code 22350 – Process Servers
Registration carries a $2,000 surety bond that protects the public if the server breaks the rules. The server can instead deposit $2,000 in cash or a money order with the county clerk. Either way, there’s an accountability layer behind the person at your door that a volunteer doesn’t carry.
What you’re really paying for is experience. Professionals know how to handle people who dodge service, understand the timing rules when a defendant is never home, and produce clean proof-of-service paperwork that holds up when challenged. Many also do skip tracing, searching public records and proprietary databases to find someone who has moved or is deliberately staying out of reach. Routine deliveries typically run $40 to $100. Difficult-to-serve defendants and rush jobs cost more.
The Sheriff or Marshal
County sheriffs are required by statute to serve process and notices in the manner the law prescribes.3California Legislative Information. California Code of Government Code 26608 – Duties A sheriff’s testimony about what happened at the door is hard for a defendant to attack.
The fee to have the sheriff serve a summons and complaint is $50, set by statute effective January 1, 2024.4California Legislative Information. Bill Text – SB-564 Sheriffs and Marshals Fees Other types of process may be priced differently. If the court has granted you a fee waiver in your case, sheriff service is free.
The trade-off is speed. Sheriff’s offices move through a steady queue of documents, and yours waits its turn. If you’re working against a tight deadline, a private server will almost always be quicker.
Which One Should You Use
Match the server to the situation. A cooperative defendant with a known home address is a reasonable job for an adult you trust, especially if cost matters more than speed. A defendant who may try to avoid service, or a case where the opponent is likely to fight back on technicalities, is worth paying a registered process server for. The sheriff makes sense when you want the weight of law enforcement behind the delivery, you’re not in a hurry, and the $50 flat fee is attractive — or free, if you have a waiver.
What the Server Has to Do After Delivery
Picking the right person is only step one. Service doesn’t count until the server documents what they did in a proof of service. The server fills out an affidavit showing the time, place, and manner of service and the name of the person who received the papers.5California Legislative Information. California Code of Civil Procedure 417.10 The Judicial Council form is POS-010, signed under penalty of perjury.6Judicial Council of California. POS-010 – Proof of Service of Summons
California now requires photographs for personal and substituted service. Each photo must carry an automatic timestamp showing the date, time, and GPS coordinates of the location. At a home, at least one photo must show the front door or entrance. At a business, it must show the office door or entrance. A server who reasonably believes a photo would create a safety risk can skip it, but must attach a written explanation to the proof of service.5California Legislative Information. California Code of Civil Procedure 417.10
If service was done by mail with acknowledgment, the proof of service includes the signed acknowledgment from the recipient instead of a photo.
This is where a casual server can get you in trouble. Missed photos, blurry timestamps, or a sloppy affidavit give the other side an opening to attack the service and set your case back weeks.
Federal Cases Filed in California
If your lawsuit is in federal court rather than California state court, the rule about who can serve looks similar on its face. Federal Rule of Civil Procedure 4 also allows anyone 18 or older who is not a party to the case to deliver the summons and complaint. The federal court can additionally order service by a U.S. Marshal or a specially appointed person, and must do so when the plaintiff has been allowed to proceed without paying filing fees.7Legal Information Institute (LII) at Cornell Law School.
