What Does a Registered Agent Do?
A registered agent — sometimes called an “agent for service of process” — is a person or company officially designated to receive legal documents on behalf of a business entity. When someone sues a corporation or LLC, the legal papers are served on the registered agent, who then forwards them to the company.
Think of it as the company’s official legal mailbox. Instead of trying to track down a corporate officer, navigate a massive office building, or figure out which location is the company’s “real” headquarters, you serve the registered agent. That is the entire point of the system — it gives every business a single, known point of contact for legal service.
Under California law, the registered agent must maintain a physical street address in California (not a P.O. box) and must be available during normal business hours to accept service. This ensures that companies doing business in California can always be reached for legal purposes, regardless of where their actual offices are located.
California Corporations Code Section 1505
The legal foundation for registered agents in California is Corporations Code Section 1505. This statute requires every corporation qualified to do business in California to designate an agent for service of process. The agent’s name and address are filed with the California Secretary of State and become part of the public record.
Section 1505 applies to both domestic corporations (those formed in California) and foreign corporations (those formed in another state but registered to do business in California). LLCs have similar requirements under the California Revised Uniform Limited Liability Company Act.
The key provisions of Section 1505 include:
The designated agent must be a natural person residing in California or a corporation that has filed a certificate with the Secretary of State authorizing it to act as an agent
The agent must have a physical address in California (not a P.O. box)
If the agent resigns or the designation is revoked, the corporation must file a new designation or the Secretary of State may become the default agent
Service on the designated agent constitutes valid service on the corporation
This last point is critical. When you serve the registered agent, you have legally served the company — period. The company cannot later claim it did not receive notice of the lawsuit.
Why Corporations Must Have a Registered Agent
The requirement exists to protect the legal system and the people who use it. Without registered agents, serving a corporation would be a logistical nightmare. Companies move offices, change names, operate from multiple locations, and use virtual addresses. Without a designated point of contact, plaintiffs would have no reliable way to serve legal documents, and companies could effectively dodge lawsuits by simply being hard to find.
The registered agent system solves this problem. No matter how large or complex a corporation is, there is always one designated person or entity responsible for accepting service. This protects plaintiffs’ right to due process and keeps the court system functioning.
For the corporations themselves, having a registered agent ensures that important legal documents are received promptly and routed to the appropriate people. A missed lawsuit can result in a default judgment — meaning the court rules against the company without the company ever presenting its side. A good registered agent prevents that from happening.
How to Find a Company’s Registered Agent
If you need to serve legal documents on a business in California, finding their registered agent is straightforward.
California Secretary of State Business Search
The California Secretary of State maintains an online business database at bizfileonline.sos.ca.gov. You can search by the company’s name or entity number to find their registered agent information, including:
The agent’s name (individual or corporate agent)
The agent’s physical address
The date the designation was filed
This is a free search and the information is public record. It is the first place you should look when preparing to serve a company.
Tips for Searching
Search the exact legal name of the business, not a trade name or DBA
If the company is an LLC, make sure to search for the LLC name specifically — it may differ from the brand name you know
Check whether the agent designation is current — companies sometimes let their agent information lapse, especially if they have moved or changed agents
If the Secretary of State shows the agent has resigned and no replacement was designated, the Secretary of State themselves may be the default agent — though this complicates service
Common Registered Agents in Sacramento
Many corporations — especially large ones or those incorporated out of state — use professional registered agent services rather than designating an individual officer. If you serve legal documents on businesses regularly, you will encounter these companies frequently:
CSC Lawyers Incorporating Service (CSC)
CSC is one of the largest registered agent companies in the country. Their Sacramento office serves as the designated agent for thousands of corporations doing business in California. If you are suing a major national company, there is a good chance CSC is their agent. We have extensive experience serving CSC in Sacramento.
CT Corporation (Wolters Kluwer)
CT Corporation, a subsidiary of Wolters Kluwer, is another major registered agent service. They maintain offices in Sacramento and act as agent for a wide range of businesses, from Fortune 500 companies to mid-size regional firms.
Cogency Global
Cogency Global provides registered agent services nationwide and maintains a presence in Sacramento. They handle service of process for numerous corporate clients across various industries.
Paracorp Incorporated
Paracorp is a Sacramento-based registered agent and corporate services company. As a local firm, they are particularly common as the designated agent for businesses that are headquartered in or have significant operations in the Sacramento area.
National Registered Agents, Inc. (NRAI)
NRAI provides registered agent services for businesses across all 50 states and is frequently listed as the agent for LLCs and corporations registered in California.
How Service of Process Works Through a Registered Agent
Serving documents through a registered agent follows the same legal requirements as any other service of process, with a few practical differences.
Step 1 — Identify the Agent
Search the California Secretary of State’s database to find the company’s current registered agent and their address. Confirm the information is up to date.
Step 2 — Prepare Your Documents
Ensure all documents to be served are complete and properly formatted. This typically includes the summons, complaint, and any other required filings. Make copies as needed.
Step 3 — Serve the Agent
A process server delivers the documents to the registered agent at their designated address. For professional agent companies like CSC and CT Corporation, this usually means visiting their office during business hours and delivering the documents to the receptionist or designated intake person.
Professional registered agent offices typically have established procedures for accepting service. They will review the documents, confirm the entity being served is one of their clients, and provide a receipt or acknowledgment of service. This is routine for them — they accept service of process all day, every day.
Step 4 — Proof of Service
The process server completes a proof of service documenting the date, time, location, and manner of delivery. This proof is what you file with the court to establish that the company was properly served.
What Happens If the Agent Refuses Service?
Registered agents are legally obligated to accept service on behalf of their designated companies. However, situations do arise where an agent may decline or create complications:
The Agent Has Resigned
If the registered agent has resigned and the company has not designated a replacement, the California Secretary of State becomes the default agent. Service can be made on the Secretary of State, but this process is slower and involves additional steps — including a fee paid to the Secretary of State and mailing copies to the company’s last known address.
The Company Is Not a Client
If you arrive at a registered agent’s office and they state the company is not one of their clients, double-check the Secretary of State records. The filing may be outdated, or you may have the wrong entity name. If the records show the company is indeed their client, the agent must accept service regardless of what their front desk staff says.
The Agent’s Office Is Closed or Unresponsive
Professional agent companies maintain regular business hours and are expected to be available. If an agent’s office is consistently closed or unresponsive, document your attempts and consult with your attorney about alternative service methods.
In practice, refusals are rare with major registered agent companies. CSC, CT Corporation, and other professional agents accept service thousands of times per year and have streamlined systems for it. Complications are more common with individual agents — a company officer designated as agent who has moved, retired, or simply does not want to deal with being served.
Why This Matters for Your Case
Getting service right is not optional. If you serve the wrong person, serve at the wrong address, or fail to properly document service, the other side can challenge it — and the court may agree. Improper service can delay your case by weeks or months and, in some cases, result in the case being dismissed entirely.
