California registered agent requirements
Check California’s rules for receiving legal notices and keeping the public contact record current. The local role may be called a registered agent, resident agent, statutory agent, or agent for service of process.
Open official agency forms and instructions ↗Who can serve in California?
California calls the registered agent the agent for service of process. The agent may be an individual resident of California or an eligible corporation authorized to act as an agent, and must maintain a California street address for service; a P.O. box alone is insufficient. The agent's name and address are public in the SOS record. A corporate agent must be authorized and in good standing; an individual agent must be available to receive process. California does not use a universal commercial/noncommercial checkbox for ordinary public searches.
California agent changes: forms and fees
A California entity changes its agent for service through the appropriate Statement of Information, amendment, or agent-change filing. The base change itself is commonly no-fee when included in a required Statement of Information, but a standalone amendment or special filing can carry a fee. Use https://www.sos.ca.gov/business-programs/business-entities/forms and BizFile Online to select the entity-specific form. The new agent must satisfy California eligibility and address requirements.
Resignation, notice, and effective dates
A California agent may resign by delivering the statutory resignation notice to the SOS and the entity and observing the effective-date and notice rules. The reviewed general business pages did not establish one universal 2026 resignation fee for every entity type; the agent-change or resignation form controls. Resignation does not appoint a successor, and the entity remains responsible for promptly designating a new California agent for service.
Consequences of a missing agent or address
Without a valid California agent for service of process, the entity can miss lawsuits and official notices, face default judgments, lose active status, and become subject to suspension or forfeiture. The SOS may provide statutory substitute-service mechanisms in limited circumstances, but that does not protect the entity from missed deadlines or eliminate the obligation to maintain a California street address and qualified agent.
Confirm the change reached the public record
Keep the accepted filing and confirm the agent or service address shown for the business. Arrange forwarding of legal notices during the change, and check which contact information will be public before supplying a home address.
