Registered Agent: What They Do and How to Choose One
Table of Contents
A registered agent receives lawsuits and state notices for your company. See what the role covers, why it's mandatory, and how to choose one.
A registered agent is the person or company a business appoints to receive official legal documents on its behalf. That includes service of process (a lawsuit), state correspondence, and tax notices. The agent must have a physical street address in the state where the company is registered and be available during normal business hours. If you form a company in another country, the same role usually exists under a local name: company secretary, resident agent, or authorized representative.
Missing a document delivered to that address can cost you the case by default. That is the whole reason the role is mandatory in most jurisdictions.
What a registered agent actually does
The job is narrower than most founders expect. The agent is a mailbox with legal weight, not a manager, lawyer, or decision-maker. The core duties:
- Maintain a physical address in the registration jurisdiction, not a PO box.
- Be reachable during standard business hours to accept hand-delivered or posted documents.
- Forward received documents to the company promptly, usually by the method agreed in the service contract.
- Keep the appointment current and file a change with the company registry when the agent or address changes.
The agent does not read your mail for you, act on deadlines, or represent you in court unless you separately hire them for that. A commercial registered agent service usually adds scanning, a document portal, and compliance reminders. Those extras are convenience, not part of the legal minimum.
Registered agent services vary widely in price and what they include, so comparing the practical differences matters more than comparing headline fees. The table below contrasts the three common ways business owners obtain a registered agent.
| Option | Typical Cost | Privacy | Availability & Handling | Main Drawbacks |
|---|---|---|---|---|
| Do it yourself (owner or employee) | State filing fee only; no service fee | None — your address appears in the public record | Must be physically present at the listed address during business hours; you handle service of process personally | Home or office address becomes public; missed or mishandled legal mail can lead to default judgments |
| Commercial registered agent service | Roughly $50–$300 per year depending on the provider and add-ons | Strong — the provider's address is listed instead of yours | Staffed during standard business hours; documents scanned and forwarded, often same day | Recurring fee; quality varies, so check whether they notify you promptly and whether they upsell bundled compliance products |
| Attorney or CPA acting as agent | Often folded into an existing engagement; may be billed hourly or as a flat annual fee | Moderate — the firm's address is public, yours stays private | Available during the firm's office hours; staff may be out of office during holidays or court appearances | Higher cost; potential conflicts if the firm also represents an opposing party; less suited to multi-state filings |
The right choice depends on how many states you operate in, how much you value keeping your home address off public filings, and how much risk you can absorb if a lawsuit or state notice arrives while you are traveling. A solo owner working from home usually gets the most value from a commercial service, while a business already paying a law firm for ongoing corporate work may find it cheaper to add the agent role to that engagement. Whichever route you take, confirm the agent has a physical street address in the state of formation (not a P.O. box), that they will forward time-sensitive documents the day they arrive, and that the arrangement is documented in writing so a change in personnel does not quietly leave you without an agent.
What is a registered agent in a foreign-owned company?
In the US, the term is "registered agent." In the UK, a company needs a registered office address but no separate agent. In Germany and many EU states, the equivalent sits in the commercial register as an address for service. In Singapore and Hong Kong, a local registered address and, in some cases, a resident company secretary are required.
For a foreign owner, the practical question is whether the jurisdiction demands a resident person, a licensed local firm, or just any physical address. Some countries accept a local address only. Others require a licensed provider or a resident individual. Check the company registry's own guidance for the jurisdiction you are using, because the requirement changes with the corporate form and sometimes with the owner's residency.
The address problem for foreign founders
You cannot usually use your home address abroad. You also cannot use a virtual office that only forwards mail, because many registries and courts require a physical location where documents can be served in person. This is where most foreign founders run into trouble: the cheap mail-forwarding service fails the "physical address" test, and the company is non-compliant from day one.
How to choose a registered agent service
Treat this as a compliance decision, not a shopping decision. The cheapest option often fails on availability or address legitimacy. Work through these criteria in order:
- Physical address in the right jurisdiction. Confirm it is a real street address and that the provider can accept hand delivery there. Ask directly.
- Registered or licensed status. Some jurisdictions require agents to be licensed or registered. Verify the provider appears on the official list where one exists.
- Availability during business hours. Ask how they handle a process server at 4:45 p.m. on a Friday. A call center that cannot accept service is a liability.
- Forwarding speed and method. Get the turnaround in writing and check whether scanned copies arrive the same day.
- Compliance add-ons. Annual report reminders and filing calendars help, but confirm whether the provider files anything or only reminds you.
- Exit terms. You must be able to change agents and file the change with the registry. Check the notice period and any termination fee.
- Cost structure. Fees vary widely by country and provider, so compare the total annual cost including forwarding, scanning, and any per-document charges, not just the headline fee.
Questions to ask before signing
Ask what happens if the agent resigns, who signs for hand-delivered documents, and whether the provider covers all the addresses your structure needs. A holding company and an operating subsidiary in two states each need their own agent in many cases.
Worked example (illustrative figures only)
Suppose a founder in Spain forms a US LLC in Delaware and a second entity in Wyoming. Each state requires its own registered agent with an in-state address. The founder signs two service contracts, pays two annual fees, and gets two document portals. When a customer files suit in Wyoming, the process server delivers to the Wyoming agent, who scans and forwards the complaint the same day. The founder has a fixed window to respond. If the agent had forwarded it a week late, the response deadline could have passed.
The numbers here are invented for illustration. Real fees, deadlines, and response windows depend on the jurisdiction and the court.
Common mistakes
Using a PO box or a mail-forwarding address that fails the physical-address rule. Letting the agent appointment lapse after a move. Assuming the agent will handle annual filings. Failing to update the registry when the agent changes. Choosing on price alone and discovering the provider cannot accept hand delivery. Each of these turns a routine document into a default judgment risk.
Practical takeaway
Pick a registered agent the way you pick an accountant: on reliability and jurisdiction fit, not on the lowest fee. Confirm the physical address, the licensing status where required, the hand-delivery process, and the forwarding turnaround before you sign. Budget for one agent per jurisdiction in your structure. Diarize the renewal date alongside your annual filings, and keep a copy of every document the agent forwards. Then verify the current rules on the official company registry for each country you operate in, because the requirement, the terminology, and the penalties differ.
