What is an agent for service of process?

All corporations must have an agent for service of process. This is the designated party upon whom a lawsuit may be served if the corporation is involved in litigation. The agent for service of process must be either a natural person residing in California, or a corporation having an office within the State of California. If a corporation serves as an agent for service of process, the corporation must file a certificate with the Secretary of State, identifying the office and person who may be served with process.
