Connecticut registered agent search is a lookup of the name and street address that a business reports as the place where lawsuits and official mail are served. Every LLC, corporation, limited partnership, limited liability partnership, and statutory trust in the state must keep one, and the appointment is part of the formation filing rather than a separate document. The agent appears on the public record, which makes it one of the few fields that reveals a real person or a professional service behind an otherwise anonymous company.
This page covers what the role requires, how to find an agent from an entity record, what a change of agent involves, and why the field matters in a contract or a dispute. It is written for owners appointing an agent and for buyers checking whether a company can actually be served. Fees appear in the table only.
How to search a Connecticut registered agent
The Business Records Search is built around the entity, not the agent, so an agent lookup starts with the business name or the ALEI. Open the record and read the registered agent field, which lists the agent’s name and the Connecticut street address where service is accepted. The same field appears on the certificate of organization and on every annual report, and it is repeated in the Connecticut filing history when a change is filed.
Find the agent from an entity record
Search the entity by name or ALEI, then read the agent block near the top of the record. The block shows the agent’s name, its street address, and sometimes a mailing address. A business that uses a commercial service shows the service name rather than an owner, which is normal and does not indicate a problem.
Find the agent from the annual report
The annual report confirms the agent and the principal office, and the acknowledgment email repeats both. If a business has changed agents since its last report, the current record shows the new agent while an older report shows the previous one. Compare the dates before you rely on either.
Confirm the agent is current
A name on the record proves that the agent was reported to the state, not that the agent still accepts service. A commercial service that closed an office, or an individual who moved, can leave a stale appointment on file. The address is the part to check, because a street address that no longer exists is the clearest sign of a problem.
Search commercial agents by name
A commercial agent appears on hundreds of records, and the search returns each entity separately. Searching the agent’s own business name in the entity register shows its own record, which confirms that the agent is registered to do business in Connecticut. That check is useful when an unfamiliar service is listed on a vendor’s record.

What a registered agent does
The agent accepts service of process, which is the legal delivery of a lawsuit or a subpoena, and receives official mail from the state. The agent then forwards the documents to the business. The role is administrative: the agent does not run the company, does not own a share, and does not make decisions for it. The appointment is a legal contact point rather than a management role, and the agent has no duty to advise the business on its filings.
Service of process
When someone sues a Connecticut business, the plaintiff serves the registered agent rather than chasing an owner. Service on the agent is legally effective even if the owner never sees the papers, which is why a stale agent is dangerous. A default judgment can follow a lawsuit the owner never knew about because the papers went to an address nobody monitored.
Official mail
The state sends annual report reminders, notices of intent to dissolve, and other official correspondence to the agent and to the email on the business account. A missed reminder is the usual path to forfeiture, and a forfeited business loses its legal existence until it is reinstated.
Consent to serve
The agent must consent to the appointment, and the consent is part of the filing. An agent who never agreed can resign, and a resignation is a filing with the state that leaves the business without a valid agent. The business then has a limited time to appoint a replacement before the state takes action.
Connecticut registered agent requirements
Connecticut requires a physical street address in the state. A post office box does not satisfy the requirement, and neither does an address outside Connecticut. The agent must be available during normal business hours, because service can arrive at any time the office is open.
Who can serve
An individual who resides in Connecticut can serve as an agent for a business they own or for another business that appoints them. A business entity authorized to transact business in Connecticut can also serve, and most commercial services are organized this way. The entity must be in good standing itself, which is why a service with a forfeited registration is a poor choice.
One agent, many entities
A single agent can serve many businesses, and a commercial service often serves thousands. Sharing an agent does not create a relationship between the businesses, and two companies with the same agent are not affiliated. The agent field is a contact point, not a statement about ownership.
Agent address versus business address
The agent address is where legal papers go. The principal office is where the business says it operates. The two can be the same for a small company working from one location, and they are usually different for a company that uses a service. Confusing them sends mail to the wrong place and makes a record look inconsistent when it is not.
Changing a registered agent
A business changes its agent by filing a change of agent with the Secretary of the State. The filing names the new agent, includes the new agent’s consent, and takes effect when accepted. The state fee is listed in the table below, and it is charged again for a change of the agent’s address.
What triggers a change
A move, a sale of the business, a switch to a commercial service, or the resignation of an individual agent all trigger a change.
A business that changes its address without telling the agent can still receive mail at the old location for a while. The gap between the move and the filing is the dangerous period, because a document delivered in that window looks served even when nobody reads it. Review the agent address every year with the annual report, and the gap closes before it causes a problem.
A business that moves its office without updating the agent address can end up with an agent address that no longer receives mail, which is the same as having no agent at all.
Resignation by the agent
An agent can resign by filing a resignation with the state and notifying the business. The resignation does not take effect immediately, and the business has a window to appoint a replacement. A business that ignores the notice can be administratively dissolved, which is a harder problem than a routine agent change.
Cost and timing
The filing is inexpensive compared with the cost of a missed lawsuit, and it is processed in the order received unless expedited service is purchased. A change made in December should be completed before the annual report window opens, so the report confirms the new agent rather than the old one.
Privacy and the agent address
A registered agent address is public. An owner who does not want a home address on the record can use a commercial agent, which puts the service address in the public field instead. That choice does not hide ownership from a court, but it does keep a home address out of a routine search.
Connecticut does not offer a full address confidentiality program for business filings in the way some states do for protected individuals. An owner with a safety concern should use a commercial agent and a separate business address rather than relying on the state to redact a record.
Service of process in practice
Service on the agent starts the clock on a lawsuit. The agent forwards the papers, and the business has a fixed time to respond. A business that never receives the papers because the agent address is stale can lose by default, and a default judgment is difficult and expensive to reopen.
The plaintiff does not have to find an owner or a manager. Service on the registered agent is enough, which is why the agent must be reachable and why the address must be current. A business that treats the agent as a formality is taking a risk it does not need to take.
Using a commercial registered agent
A commercial service charges an annual fee and provides a street address, a scanning and forwarding service, and a reminder when a filing is due. It also provides continuity when an owner moves, which is the main reason businesses switch from an individual to a service.
The cost of a service is usually small compared with the cost of a missed notice. A service that forwards documents by email the same day is worth more than one that holds paper for a week, because the response deadline does not wait for the mail. Ask how the service handles service of process before you appoint it.

Checking an agent in a contract
An agent check answers one question: can this business be served? A vendor with a commercial agent and a valid address is easier to sue than one with an individual agent who moved two years ago. That does not make the vendor honest, but it does make a dispute resolvable.
Read the agent field together with the principal office and the status. A business with an active status, a current agent, and a principal office that matches its website is a normal record. A business with a stale agent, a forfeited status, and a principal office that is a mailbox is a record that needs questions before a contract.
What happens when a lawsuit arrives
Service of process is the moment the agent’s role matters. The plaintiff delivers the summons and complaint to the agent’s street address, and the agent signs for them. Service on the agent is legally effective against the business even when the owner never sees the papers, so the forwarding task is not optional.
A commercial agent usually scans the documents and emails them the same day, then forwards the originals. An individual agent may be slower or may not recognize the importance of the envelope. The business has a fixed deadline to respond, and a late response can produce a default judgment that is expensive to reopen.
Keep a record of every document the agent forwards. A dispute about whether service was proper often turns on the date and the address, and the agent’s forwarding log is the evidence. If the agent cannot produce a log, the business should consider a service that can.
Individual agent or commercial service
An individual agent costs nothing and keeps the appointment simple. The owner is reachable, the address is familiar, and the state filing is a single line. The risk appears when the owner moves, travels, or changes the business address without filing a change, and the agent address becomes a place where mail is no longer collected.
A commercial service costs a modest annual fee and removes that risk. The service keeps a permanent street address, scans documents, and sends reminders before the annual report window opens. For a business with owners in another state, or a business that expects to move, the service is usually the safer choice.
A hybrid arrangement is frequent: the owner serves as agent for a single-location business and switches to a service when a second location or an out-of-state owner appears. The switch is a routine filing, and the state fee is the same whether the new agent is a person or a company.
Registered agents in other states
A business that operates in several states needs an agent in each state where it registers. Connecticut accepts a Connecticut agent for a Connecticut registration, and it does not accept an agent in another state for that filing. A company registered in five states usually has five agent appointments and five annual reports.
A commercial service with a national network bundles those appointments, which is why multi-state businesses often use one provider. The state records remain separate, and a search in Connecticut shows only the Connecticut agent. A buyer checking a national vendor should check each state record rather than assuming one appointment covers the country.
Agent records and out-of-state owners
Connecticut does not require an owner to live in the state, but it does require an agent who does. An out-of-state owner can form a Connecticut LLC, hold the membership interest, and run the business from another state, provided the agent has a Connecticut street address. That structure is normal and does not change the tax or the liability treatment by itself.
The agent field is often the only Connecticut address on the record, which makes it the practical contact point for the state and for a plaintiff. An owner who uses a home address as the agent address puts that address on a public record. A commercial service avoids that exposure without hiding the ownership from a court.
What the agent record cannot tell you
The agent field does not show ownership, authority, or financial standing. An agent can be a stranger who agreed to accept mail, and the appointment says nothing about who controls the company. It also does not prove that the agent is still in business, because the state does not verify the address on a schedule.
The field is a contact point, and the record is only as current as the last filing. A change of address that was never filed does not appear, and a service that closed an office may still be listed. Treat the agent as a lead, confirm the address, and keep a dated copy of the record.
Frequent registered agent mistakes
Most agent problems come from a few habits that are easy to correct. The appointment is public, the address matters more than the name, and a change is a filing rather than an email to the state.
- Using a post office box. Connecticut requires a street address in the state.
- Forgetting the agent address after a move. The business address and the agent address are separate fields.
- Assuming the agent owns the company. The appointment is administrative, not an ownership record, and the Connecticut LLC lookup page shows how the field sits on an LLC record.
- Ignoring a resignation notice. A business without an agent can be dissolved.
- Filing the annual report without checking the agent. The report confirms whatever is on file, including an old address.
Frequently asked questions
The questions below come from owners appointing an agent and from buyers checking whether a business can be served. Every response names the office or the field behind it.
Does Connecticut require a registered agent?
Yes. Every LLC, corporation, partnership, LLP, and statutory trust must keep a registered agent with a Connecticut street address. The appointment is part of the formation filing, and a change is a separate filing with its own fee.
Can I be my own registered agent in Connecticut?
Yes, if you reside in Connecticut and have a street address in the state. An owner who lives out of state cannot serve and must appoint a resident individual or a registered business entity.
Is a registered agent the same as a statutory agent?
Connecticut uses both terms. The statutes and the modern portal refer to a registered agent, while some forms describe the appointment as a statutory agent. They describe the same role.
What happens if my registered agent resigns?
The agent files a resignation and notifies the business. The business has a limited window to appoint a replacement, and a business that ignores the notice can be administratively dissolved. The Connecticut business status page covers what a dissolved record looks like.
Can a registered agent be sued instead of the business?
No. The agent accepts service on behalf of the business and is not a party to the dispute. The lawsuit is against the entity, and the agent’s role is to make sure the entity receives the papers.
