An agent for service of process, also known as the registered agent, is the person or company designated to accept service of process on behalf of the limited liability company. In any lawsuit, the defendant must be "served" with court papers, which give the defendant notice, before the lawsuit can have legal effect. Once the court papers have been delivered to the registered agent, the LLC is deemed to be on notice. The name and address of the registered agent is public information. Therefore, if you prefer an extra layer of privacy or do not have an address in the state of formation, LegalZoom can serve as your registered agent for $149 per year. LegalZoom, through its affiliates, can serve as a registered agent in all 50 states.
