Every California LLC and corporation must continuously designate an agent for service of process — the person or company authorized to receive lawsuits and official notices on the entity's behalf. It is the least glamorous line on your formation documents, and one of the most consequential: get it wrong and you can lose a lawsuit you never knew existed. Here is what the law actually requires and how to choose well.
What the agent is for
The registered agent (California's statutes call it the "agent for service of process") exists so that anyone with a legal claim against your company has a reliable, public place to serve it. When a process server delivers a summons and complaint to your agent, your company has been served — whether or not the paperwork ever reaches you. The agent's name — and, for an individual agent, address — appears in your Articles and your Statement of Information, both public records, and plaintiffs and process servers rely on that information for service.
Who can serve — the legal requirements
California gives you two options, set out in the Corporations Code (§ 1502 for corporations, § 17701.13 for LLCs):
- An individual who resides in California, designated with a physical California street address — a post office box does not qualify. The individual should be reliably available at that address during business hours to accept service. An owner, officer, or any willing California resident can serve, but the entity cannot name itself as its own agent;
- A registered corporate agent — a company that has filed a certificate under Corporations Code § 1505 authorizing it to act as an agent for other entities. Commercial registered agent services operate under this section.
The designation must stay current. If your agent resigns, moves, or the address changes, you update it through the Statement of Information (or a separate filing), and the obligation is continuous for as long as the entity exists.
Should you be your own agent?
Many small-business owners name themselves. It is legal and free, but weigh three practical costs. First, the address goes on the public record permanently searchable online — home-based businesses in particular may not want that. Second, service can arrive in front of employees or customers; being served at your own front counter is nobody's favorite Tuesday. Third, and most important, you should be reliably present at that address during business hours — a solo owner who travels, works from client sites, or moves without updating the state creates a gap where service happens without notice. Commercial agents typically cost $50–$150 per year, forward documents the day they arrive, and keep your home address out of the agent field on formation documents. For most owner-operated companies, that is money well spent; the right answer depends on how you actually work.
What goes wrong when the agent fails
The failure modes are predictable and painful:
- Default judgment. If your agent's address is stale and a plaintiff cannot serve the designated agent, the plaintiff may, after diligent attempts fail, obtain court approval to serve the Secretary of State under Corporations Code § 1702 or § 17701.16. The case may then proceed without you. The first you hear of it may be a levy on your bank account. Setting aside a default is possible in some circumstances but is expensive, uncertain, and urgent;
- Suspension. An entity that fails to file its Statement of Information — the filing that keeps agent details current — faces penalties and eventual suspension by the Secretary of State. A suspended entity cannot prosecute or defend a lawsuit or enforce its contracts, and its name becomes available to others;
- Missed government notices. Franchise Tax Board and Secretary of State notices sent to a dead address may not pause deadlines; penalties and interest can accrue silently.
If you have moved, changed agents informally, or cannot remember what address is on file, pull your entity's record on the Secretary of State's website today and check. Keeping the agent designation, the Statement of Information, and your corporate records aligned is basic entity hygiene — and if the records have drifted, a corporate governance cleanup is far cheaper than a motion to vacate a default judgment.
