What Is an Agent for Service of Process in California?

An agent for service of process is the individual or corporation that a California business entity designates to receive legal documents and official state correspondence. California law requires every LLC, corporation, limited partnership, and foreign-qualified entity to maintain an agent with a physical street address in the state.

The Role Under California Law

The California Corporations Code establishes the requirements for agents for service of process. The agent's responsibilities include:

Accepting Service of Process When someone files a lawsuit against your business, the complaint and summons must be formally delivered — "served" — on your agent for service of process. This is the agent's primary function and the reason California uses this specific terminology.

Receiving Secretary of State Correspondence The California Secretary of State sends official notices, filing confirmations, and compliance reminders to the address on file for your agent.

Receiving Franchise Tax Board Notices Tax-related correspondence from the FTB may also be directed through your agent's address.

Who Can Serve as Agent for Service of Process

California has specific eligibility rules:

Individuals: Any California resident who is at least 18 years old and has a physical street address in California. The individual must be available at that address during normal business hours.

Corporations: A corporation can serve as agent for service of process, but only after filing a Section 1505 Certificate with the California Secretary of State.

Who Cannot Serve:

• LLCs — California is one of the few states that explicitly bars LLCs from serving as agents for service of process
• The business entity itself — you cannot appoint your own company as its own agent
• Anyone without a physical California address — PO boxes do not qualify

Why the Terminology Matters

Most states call this role "registered agent" or "statutory agent." California's choice of "agent for service of process" is more descriptive and emphasizes the legal function. If you are researching compliance across multiple states, know that the role is functionally identical regardless of the name each state uses.

Consequences of Not Having an Agent

If your California entity does not have a valid agent for service of process on file:

• The Secretary of State may administratively suspend your entity
• You may lose the ability to conduct business, enter contracts, or access California courts
• If sued, a court may authorize alternative service — meaning you could receive a default judgment without being properly notified
• Reinstatement requires filing fees and penalties

• A reliable California address that is always staffed during business hours
