Service of Process in California: How a Business Gets Served

What service of process is

Service of process is the formal delivery of court papers to the party being sued. For a business it usually means a summons and complaint, but subpoenas, small claims filings, and wage garnishment orders can travel the same way. The point of the formality is fairness: a court will not rule against a company that was never properly told about the case. That is also why California requires every corporation and LLC to keep an agent for service of process on file with the Secretary of State. The agent is the address the law guarantees will work.

Who can be handed the papers

A process server does not have to find the owner. California law names several people who count as the business for this purpose.

Entity	Who may be served	Where the rule is
Corporation	People including the designated agent for service of process, the president, chief executive officer, a vice president, the secretary, treasurer, chief financial officer, general manager, or anyone the corporation authorized to accept service	Code of Civil Procedure section 416.10
LLC	The designated agent for service of process (if the agent is a company, a person named on its section 1505 certificate, at the agent's office); the general methods in the Code of Civil Procedure also apply	Corporations Code section 17701.16
Either, when the agent cannot be found	The Secretary of State, by court order (see below)	Corporations Code sections 1702 and 17701.16

Process servers go to the agent first because it is the sure thing. The agent's California street address is on the public record, someone is expected to be there during business hours, and delivery to the agent is complete service with no argument later about whether the right person was found. That predictability is the whole value of the role, and it is why the agent has to be a real, staffed California address rather than a P.O. Box.

What actually happens, step by step

1. The plaintiff files the case and the court issues a summons. The plaintiff is responsible for having it served on you, usually by a process server or the sheriff; a party to the case cannot serve the papers personally.
2. The server looks up your agent on the Secretary of State's business search. If the record is current, the server goes straight to that address.
3. The papers are handed to your agent or to a person there authorized to accept them. The server records the date, time, and who accepted, and later files a proof of service with the court.
4. When the papers are handed over in person, service is complete at that moment. The response deadline runs from this date. For a standard civil summons, California gives the defendant 30 days after service to respond.
5. Your agent gets the papers to you. At Corpgate, Inc. that means the documents are scanned and emailed promptly, with the hard copy forwarded.
6. You respond through your attorney, or you don't. A business that lets the deadline pass can lose by default, with the merits never heard.

The part that surprises owners: the clock starts when the agent is served, not when you open the envelope. Every day the papers sit between the agent and you comes out of your response window. That is the real difference between one agent and another.

Other ways a business can be served

Personal delivery to the agent is the normal route, but California allows a few others, and they all still start the clock.

Substituted service. Instead of handing the papers to the agent or an officer, the server may leave them during usual office hours with the person apparently in charge of that office, then mail a copy there. Service is complete on the 10th day after the mailing.
Mail with acknowledgment. The papers arrive by mail with a notice and acknowledgment form. Service is effective only if the form is signed and returned; if it is not, the plaintiff serves another way and may recover the cost.
Service on the Secretary of State. If your agent has resigned without a replacement, moved without telling the state, or simply cannot be found with reasonable diligence, the court can order the papers delivered to the Secretary of State instead. The state forwards them by registered mail to your entity's principal office address on its records, and service is deemed complete on the tenth day after delivery to the Secretary of State, whether or not that mail ever reaches you.

The last one is the trap. A company with a lapsed or unreachable agent can be validly served without anyone at the company knowing, and the first news is often a default judgment. Our guide on what happens without a working agent follows that path in detail.

Small claims, subpoenas, and garnishments

Not everything that arrives is a full lawsuit. Small claims plaintiffs serve a business the same way, through the agent, and the hearing date is printed on the papers. A subpoena for records or testimony is served on the agent too, usually with a shorter deadline. Earnings withholding orders for an employee's wages can come to the employer through the agent too, but they are often mailed to the business or delivered to the office where the employee works, with strict timelines for the employer's response. All of them deserve the same treatment: date-stamp, read, forward to the right person right away.

Where the agent fits

Your agent's job begins and ends with the handoff: accept the papers, record the date, and get them to you fast. The agent does not answer the court, give legal advice, or represent the company. Choosing one comes down to whether the address will be staffed every business day for years and how quickly the forwarding happens. Corpgate, Inc. has been the agent for California LLCs and California corporations since 2008, owner-operated, with documents scanned and emailed promptly and flat pricing at $49 a year on a 3-year plan or $79 year to year. If you need to switch, engage the new agent first and then file the form that names them; the walkthrough is in our guide to changing your registered agent.

Service of process questions

Who can be served on behalf of a California corporation or LLC?

The agent for service of process the entity designated with the Secretary of State, or certain officers and managers. For a corporation, Code of Civil Procedure section 416.10 lists people including the agent, the president, chief executive officer, vice president, secretary, treasurer, chief financial officer, general manager, or anyone the corporation authorized to accept service. For an LLC, Corporations Code section 17701.16 points to the designated agent. Serving the agent is the clean, predictable route, which is why process servers go there first.

When does the clock start on a lawsuit served on my business?

When the papers are handed in person to your agent or another person the law allows to accept them, service is complete that day. Other methods take longer: substituted service is complete on the 10th day after the mailing, and service through the Secretary of State on the 10th day after delivery to the Secretary of State. A California summons tells the defendant to respond within 30 days after service. That count begins on the day of service, not the day the papers reach your desk, so the speed of your agent's forwarding decides how much of that window you keep. A licensed attorney can confirm the deadline that applies to your case.

What happens if a process server cannot find our agent?

California law has a fallback. If the agent has resigned, moved without updating the state, or cannot be found with reasonable diligence, a court can order service on the Secretary of State instead. The Secretary of State forwards the papers by registered mail to your entity's principal office address on its records, and service is deemed complete on the tenth day after the papers were delivered to the Secretary of State, whether or not the mail ever reaches you. That is the situation a reliable agent exists to prevent.

Can a business be served by mail in California?

Sometimes. California allows service by mail with a notice and acknowledgment form, which is effective only if the defendant signs and returns the acknowledgment. Substituted service, which involves leaving the papers with the person apparently in charge at the office and then mailing a copy, is also possible. Neither replaces the agent requirement, and both still start a response clock once complete.

What should we do the day we are served?

Note the date you were served and the response deadline printed on the papers, keep the complete packet together, and contact your attorney. A business that misses its response deadline can lose by default without the merits ever being heard. Talk to your attorney about your specific situation.

Does my registered agent handle the lawsuit for me?

No. The agent's job is to accept the papers and get them to you promptly, with the hard copy following. The agent does not respond to the court, give legal advice, or represent the business. Corpgate, Inc. scans and emails documents to you promptly and forwards the originals; what happens after that is between you and your attorney.

This guide is general information, not legal advice. Deadlines depend on the court and the document served; consult a licensed attorney about any papers your business receives.
