What is an agent for service of process?
An agent for service of process is the person or company a business entity designates to receive legal documents on its behalf. The most important of those is service of process: the formal delivery of a summons, complaint, subpoena, or similar document when the entity is a party to a legal action. The agent also receives official documents from the state regarding the entity.
"Agent for service of process" is California's statutory term. In most other states, and in everyday conversation, the same role is called a registered agent. If you've been told your LLC or corporation needs a "registered agent," this is that requirement. For a plain walkthrough of the role itself, see our guide on what a registered agent does. This page covers California's requirement specifically and how to meet it.
Why California requires one
Due process requires that a business can be reliably notified when it's sued. California solves this by requiring every corporation and LLC, domestic or out-of-state, that's organized or doing business in the state to designate and continuously maintain an agent for service of process at a physical California address. The designation is made in your formation or registration filing and kept current in your Statement of Information.
The requirement never pauses. An entity that lets its agent lapse faces negative actions with the state, and can end up unaware of a lawsuit until deadlines have already passed.
Who can serve
California law gives two options:
- An individual: any adult California resident with a physical street address (not a P.O. Box) who will reliably be available there during business hours
- A professional corporate agent: a corporation registered with the Secretary of State under Corporations Code section 1505, like Corpgate, Inc.
The entity cannot name itself. One practical difference: entities that select a 1505 corporate agent list only the agent's name on state filings, because the Secretary of State already has the agent's address on file from its 1505 registration.
What actually happens when your business is served
Most businesses never see a service of process. When one does arrive, the sequence is short and the timing is what matters:
- A process server delivers the documents to your agent at the California address on file with the state, and hands them to a person authorized to accept service there.
- Service is complete at that moment. This is the part that catches people out: the clock on your response starts when your agent is served, not when you happen to read about it. How long you have depends on the court and the document, and a licensed attorney can tell you what applies.
- Your agent forwards the documents to you. How fast that happens is the entire practical difference between one agent and another, because it decides how much of your response window you actually get to use.
- You respond, or you don't. A business that never learns it was sued can lose by default, without the merits ever being heard.
State mail runs through the same channel. Notices about your entity's standing, and reminders tied to your Statement of Information, arrive at the agent's address too. An agent nobody is monitoring is how compliance problems go unnoticed until they are expensive. Our guide on what happens without a working agent covers that path in detail.
Process agent, agent of process, and the other names for this
The same role collects a lot of labels, and searching for the wrong one sends you to the wrong place. In California all of these mean the agent for service of process:
| What you might search or hear | What it means in California |
|---|---|
| Registered agent | The same role. The common term in most other states and in ordinary speech. |
| Process agent, agent of process, agent of service | Informal shorthand for the same role. Not California's statutory wording, but people use them constantly. |
| California Registered Corporate Agent (1505) | What state forms call your agent when the agent is a company. See our guide to the 1505 corporate agent. |
| Statutory agent, resident agent | Other states' names for it, not California's. Our state-by-state terminology guide lines them up. |
Out-of-state companies doing business in California
A corporation or LLC formed elsewhere and registered to transact business in California carries the same obligation as a California entity: a California agent for service of process, at a physical California street address. Your registered agent in your home state does not satisfy it, and neither does your own out-of-state office. Details in our guide for out-of-state companies in California.
How to name or change your agent
Your agent is designated in your formation or registration filing, and kept current through the Statement of Information, which is also the filing you use to switch. The order matters: engage the new agent first, then file the form naming them. Full walkthrough in our guide to changing your registered agent in California.

Agent for service of process: FAQ
Is an agent for service of process the same as a registered agent?
Yes. “Agent for service of process” is the term California uses in its statutes and forms; “registered agent” is the common name used in most other states and in everyday speech. They refer to the same required role.
Who can serve as an agent for service of process in California?
Either an individual California resident with a physical street address, or a corporation registered with the Secretary of State under Corporations Code section 1505 to act as a professional agent. An entity cannot serve as its own agent.
What happens if my business doesn't maintain an agent?
Failing to designate and maintain an agent leads to negative actions with the state, and a plaintiff may be permitted to serve your entity through alternative means, which can mean a lawsuit proceeds without your knowledge until deadlines have passed.
What does Corpgate, Inc. do when a document arrives?
We scan it and email it to you promptly, and the hard copy is forwarded to you. Most clients never receive a service of process at all, but when it happens, speed and reliability matter.
Is a process agent the same as an agent for service of process?
In California, yes. "Process agent," "agent of process" and "agent of service" are all informal shorthand for the agent for service of process. One exception worth knowing: in trucking, a BOC-3 process agent is a separate federal FMCSA designation for motor carriers, brokers and freight forwarders, and it is not the same as your state agent. Corpgate, Inc. does not provide BOC-3 service.
When is my company officially served?
At the moment the documents are delivered to your agent at the California address on file, not when the agent forwards them to you and not when you read them. That is why how quickly your agent passes documents along matters so much: it determines how much of your response window is left. How long you have to respond depends on the court and the document, so consult a licensed attorney about your situation.
Can my out-of-state registered agent cover California?
No. If your corporation or LLC is registered to transact business in California, you need an agent with a physical California street address. An agent in your formation state does not satisfy the California requirement, and neither does your own office outside California.
Do I put my agent's address on my California filing?
It depends on the agent. If you name a company registered under Corporations Code section 1505, you enter its registered name only and leave the address blank, because the Secretary of State already holds that address. If you name an individual, you supply their name and a physical California street address.
How much does an agent for service of process cost?
Professional agents in California typically charge $100 to $300 per year. Corpgate, Inc. charges $49 per year with a 3-year plan (one $147 payment) or $79 year to year, with no additional fees.
