Who can serve

California registered agent requirements

  • Physical California address. P.O. Boxes are not accepted. Must be a street address where the agent is physically available during business hours.
  • At least 18 years old. Minors cannot serve as registered agents.
  • California resident or authorized business entity. Individuals must be California residents. Entities must be authorized to do business in California.
  • Acceptance of appointment. The agent must formally accept the appointment. California rejects filings where the acceptance is missing.
  • Available during regular business hours. The address must be staffed to accept Service of Process and official state correspondence.
Yourself vs Professional

Can I be my own registered agent in California?

Yes, if you meet the requirements above. But most founders choose a professional service because of three real downsides to being your own agent:

Your home address becomes public

Your registered agent address is published on the California Secretary of State (BizFile) business record. Anyone can look it up. Most founders prefer their home address stay private.

You must be present during business hours

Service of Process and official mail must be received in person during business hours. Travel, vacation, or being out of office can result in missed delivery and default judgments.

You must file a change every time you move

Every move requires a Statement of Change filing ($25 California fee). A professional service does not move when you move.

How to change

How to change your California registered agent

  1. 1Choose your new agent. Confirm they meet California requirements and have agreed to serve.
  2. 2Prepare a Statement of Change. California requires the new agent to sign accepting the appointment.
  3. 3File with the California Secretary of State, Business Programs Division. Fee: $25. The change is effective the day the state stamps the filing.
  4. 4Notify your existing agent. If you are using a paid service, inform them to avoid double-charging on renewal.

File.Business handles the entire change in 5 minutes. We prepare the Statement of Change, sign as the new agent, file with California, and confirm when stamped. Just give us your entity name.
