How to Change the Registered Agent for a Connecticut LLP

A registered agent isn't a set-it-and-forget-it decision. Circumstances change, and when they do, the state record has to change with them. Here are the common triggers.

Your current agent resigned or quit

Registered agents can resign. If your agent — whether a commercial service, a partner, or a friend — steps down, you need a replacement on file quickly. A resigning agent typically notifies both you and the state, and until you name a successor, your LLP is exposed to the risk of missing service of process.

The agent moved or is no longer available

If a partner served as your agent and has moved out of Connecticut, changed addresses, or is no longer reliably available during business hours, the agent record is no longer valid. Connecticut requires a physical in-state street address staffed during business hours, so a move can force a change even if the person is willing to keep serving.

You're switching to a commercial service

Many partnerships start with a partner as the agent and later switch to a commercial registered agent service — to get a home address off the public record, to stop worrying about coverage during travel, or simply to consolidate compliance with one provider. This is one of the most common reasons partnerships file a change.

Your commercial provider isn't working out

If your current commercial agent is slow to forward documents, hard to reach, or overpriced, you can move to a different provider. The change process is the same regardless of who your old and new agents are.

Changing your registered agent means filing a change with the Connecticut Secretary of the State's Business Services Division so that the state's record reflects your new agent. The filing is made through the CT Business One Stop portal at business.ct.gov.

What the change filing requires

• Your LLP's exact legal name as it appears on the state record
• The name of your new registered agent — an eligible individual or a commercial registered agent service
• The new agent's physical Connecticut street address (the new registered office)
• Consent from the new agent to serve in the role

The order of operations

Line up your new agent first, then file the change. If you're moving to a commercial service, that service will typically provide the address and consent you need for the filing — and often handles the filing itself. Don't cancel your old arrangement before the new agent is confirmed on the record, or you'll create a gap where the LLP has no valid agent.

Processing

Online changes are generally processed within a couple of business days. Once processed, the new agent appears on your LLP's public record and immediately becomes the party the state and courts will deliver documents to.

A registered agent change is a targeted update. It's worth knowing what it touches and what it leaves alone.

What it changes

• The name and address of the party authorized to receive service of process and state mail for your LLP
• The registered office address on your public record

What it does not change

• Your LLP's legal existence: The partnership continues uninterrupted; you're only updating a contact, not re-registering.
• Your principal office address: That's a separate field. If your business address changed too, update it as well.
• Your annual report obligation: The report is still due on its normal schedule regardless of an agent change.
• Your EIN or tax accounts: Federal and state tax registrations are unaffected.

Keep the old agent informed

If you're leaving a commercial agent, let them know so they can close out your account and stop billing you. If a partner is stepping down as agent, make sure they understand they're no longer responsible for receiving the partnership's legal mail once the change is processed.

You can file a registered agent change yourself through the state portal, but the paperwork has to be exact — the LLP name must match the state record precisely, the new agent's address must be a valid Connecticut registered office, and the new agent has to consent. A mistake means a rejected filing and more delay.

What we do

• Confirm your LLP's exact name as it appears on the Connecticut record
• Provide our Connecticut registered office address and consent if you're switching to us
• Prepare and submit the change filing with the Secretary of the State
• Confirm the change once it's processed and the new agent is live on your record

Switching to us as your agent

If you're moving your registered agent to Mainstay Filing, we handle both sides: we become your agent and we file the change that puts us on the record. From then on, legal papers and state notices come to our Connecticut address, and we forward them to you promptly and track your annual report deadline. The switch is designed to be clean, with no gap in coverage where your LLP is left without a valid agent.

A registered agent change is low-drama when you sequence it correctly, and a source of missed mail when you don't. Here's the order that avoids gaps and surprises.

The safe sequence

1. Confirm the new agent first. Line up the replacement — a commercial service or an eligible individual with a Connecticut street address — and get their consent to serve before you touch anything.
2. File the change with the Secretary of the State naming the new agent and their registered office.
3. Wait for processing. The new agent isn't the official recipient until the change is on the record, so don't treat the handoff as done until it's processed.
4. Close out the old arrangement. Only after the change is live should you cancel a departing commercial service or relieve a partner who was serving as agent.

Why the order matters

If you cancel the old agent before the new one is confirmed on the record, there's a window where your LLP has no valid agent — exactly when a lawsuit or state notice could arrive with no one authorized to receive it. Sequencing the steps keeps coverage continuous.

Tell the people who need to know

Once the change is processed, let anyone who regularly serves or corresponds with the partnership know the new address, and update your internal records so partners aren't sending compliance mail to a stale contact. A registered agent change is quiet, but the people relying on the old information should hear about the new one.
