Connecticut Registered Agent Requirements for an LLC

Updated September 6, 2026. Quick answer: In Connecticut, this role is called a registered agent, governed by Conn. Gen. Stat. Section 34-243n (registered agent), Section 34-243o (change), Section 34-243r (service of process), Section 34-243u (fees). Connecticut has no Secretary-of-State-as-default-agent mechanism for a domestic LLC at all, and this session found no registered-agent-specific dissolution trigger in the Act, a genuine deviation from the more common ‘no agent leads to dissolution’ pattern.

What the address rule requires

Connecticut’s statute requires the agent’s address to include the street and number, and requires the agent to have a place of business in the state.

Who can serve as your registered agent

A natural person resident in Connecticut; a Connecticut corporation; a foreign corporation authorized in Connecticut; an LLC; a registered foreign LLC; or a Connecticut or foreign-authorized registered limited liability partnership or statutory trust. The statute’s list for domestic LLCs does not include the Secretary of the State as an option (that option exists only for foreign LLCs).

What happens if you don’t have one

If the LLC ceases to have a registered agent, or the agent cannot be served with reasonable diligence, it may be served by registered or certified mail, or a similar commercial delivery service, addressed to the company at its principal office. Connecticut’s statute does not provide for the Secretary of the State to become the LLC’s default agent for a domestic LLC. No explicit administrative-dissolution clause specific to a registered-agent lapse was found in this session’s reading of the LLC Act; the statute’s practical remedy is the mail-to-principal-office service option above rather than a stated forced-dissolution timeline for this ground alone.
