Delaware Registered Agent Requirements (2026)

Q: Does a Delaware LLC need a registered agent?

Yes. Section 18-104 of the Delaware LLC Act requires every LLC to continuously maintain a registered agent with a physical Delaware business office. You name the agent on the Certificate of Formation, and the agent receives service of process and official notices.

Q: Can I be my own registered agent in Delaware?

You can if you have a physical Delaware business office and are available during business hours. Most owners outside Delaware cannot meet the in-state address rule, so they hire a commercial registered agent that maintains a Delaware office.

Q: Who can serve as a Delaware registered agent?

An individual Delaware resident, the entity itself in limited cases, or a domestic or qualified foreign business entity with a Delaware business office. A commercial registered agent that lists many entities must be registered with the Division of Corporations.

Q: How do I change my Delaware registered agent?

File a Certificate of Change of Registered Agent with the Delaware Division of Corporations. The new agent must consent. If your current agent resigns, you must appoint a replacement to keep the LLC in good standing.

What a Delaware Registered Agent Is

A Delaware registered agent is the person or business your LLC designates to receive service of process (lawsuit papers), tax notices, and official correspondence from the state. The agent sits at a registered office - a physical Delaware address on record with the Delaware Division of Corporations. The role exists so that anyone suing the LLC, and the state itself, always has a reliable Delaware address to reach it. For the concept in general, see the national registered agent overview.

The registered agent is not the same as the LLC's owner, manager, or lawyer, although one person can hold more than one of those roles. The agent's job is narrow but important: be reachable at the registered office during business hours and promptly forward anything received to the LLC.

Why does Delaware insist on this? The state - and anyone with a legal claim - needs a guaranteed way to deliver documents to a company that may have no offices, employees, or even owners inside Delaware. A huge share of Delaware entities are owned by people who live elsewhere, so the registered agent is the fixed point of contact that keeps the entity reachable. Without it, a plaintiff could not reliably serve a lawsuit and the state could not deliver tax notices. The agent requirement is what makes the "form in Delaware, operate anywhere" model work.

The Legal Requirement (Section 18-104)

Under Section 18-104 of the Delaware Limited Liability Company Act (Title 6, Chapter 18), every LLC must at all times maintain in Delaware both a registered office and a registered agent for service of process. The registered office does not need to be the LLC's place of business. You designate the agent when you file the Certificate of Formation under Section 18-201, which requires the agent's name and the registered office address. The requirement is continuous - it applies for the entire life of the LLC, not just at formation. See how to form an LLC in Delaware for where the agent fits in the filing.

The statute also ties the registered office and the registered agent together. The registered office is simply the Delaware street address at which the agent can be found; the two must match. If the agent moves, the registered office of every entity it represents moves with it, and the agent files to update the address. Because the requirement runs continuously, an LLC that lets its agent lapse is technically out of compliance with Section 18-104, which is why the practical advice is to always have a successor lined up before an existing agent stops serving.

Who Can Serve as a Registered Agent

Section 18-104 allows several types of registered agent. The table below summarizes the qualifying categories.

Type of agent	Requirement
Individual resident of Delaware	Must have a Delaware business office address identical to the registered office
The LLC itself	Permitted only in limited circumstances where the LLC maintains its own Delaware office
Domestic business entity	A Delaware corporation, LLC, LP, or similar entity with a Delaware business office
Qualified foreign business entity	An out-of-state entity authorized to do business in Delaware, with a Delaware office
Commercial registered agent	An agent listing many entities must register as a commercial registered agent with the Division of Corporations

In every case, the agent must have a physical Delaware street address - a post office box alone does not satisfy the registered office requirement.

Can You Be Your Own Agent?

You can act as your own Delaware registered agent only if you personally maintain a physical Delaware business office and are available there during normal business hours to accept service of process. Because most LLC owners who choose Delaware live and work elsewhere, they cannot meet the in-state address rule and instead hire a commercial registered agent. A commercial agent maintains a staffed Delaware office, is listed with the Division of Corporations, and forwards documents to you - usually for a flat annual fee that the state does not set.

Even Delaware residents who could serve as their own agent often choose not to. Serving as your own agent means your name and street address appear on the public record, and it means you must be personally present to accept a lawsuit - being served with a complaint at your home or storefront, sometimes in front of customers, is a common reason owners switch to a commercial agent. It also ties the LLC's compliance to your availability: if you travel, move, or are simply out when papers arrive, the LLC can miss a critical deadline. A commercial agent removes that single point of failure.

Using a Commercial Registered Agent

Most out-of-state Delaware LLCs use a commercial registered agent. The benefits are a reliable Delaware address, privacy (the agent's address appears on the public record instead of your home address), and consistent handling of legal and tax mail. The state does not regulate the agent's fee, so it varies by provider; this is a private cost on top of the state's Delaware LLC cost. Because the agent forwards your annual-tax reminders and any lawsuit papers, choose one that is responsive and stable. If your agent goes out of business or resigns, you are responsible for appointing a replacement immediately.

How to Change or Replace Your Agent

To change your Delaware registered agent, you file a Certificate of Change of Registered Agent (and, if applicable, registered office) with the Division of Corporations. The new agent must consent to the appointment. If your current agent resigns, Delaware law gives the LLC a window to appoint a successor; if you do not, the resignation takes effect and the LLC is left without an agent. A registered agent may also change its own name or address by filing with the Division. Keep the agent information current so state notices and legal papers actually reach you.

Owners most often change agents for three reasons: they are unhappy with a provider's service or price, they are consolidating many entities under one agent, or their current agent has gone out of business. In the last case, act quickly - an LLC whose agent has vanished is out of compliance until it names a replacement. When you switch, confirm that the outgoing agent has forwarded any pending mail and that your annual-tax reminders will now route to the new agent, since a missed reminder can lead to a late $400 tax payment and the resulting penalty.

Delaware also regulates agents that list large numbers of entities. A commercial registered agent - generally one that serves 50 or more entities - must itself be listed with the Division of Corporations and maintain a genuine Delaware business office with staff available during business hours. This rule exists so that the address on file is a real, reachable location rather than an empty mailbox, which protects the reliability of service of process for everyone dealing with Delaware entities.

What Happens If You Don't Maintain One

Failing to maintain a registered agent violates Section 18-104 and puts the LLC's standing at risk. The most immediate danger is practical: without an agent, the LLC can miss a lawsuit and have a default judgment entered against it, or miss the annual-tax notice and fall behind on the flat $400 tax. Over time, an LLC without an agent can lose good standing and ultimately have its status voided. Restoring it generally requires appointing a new agent, filing a revival, and paying any back taxes and penalties. See how to dissolve an LLC in Delaware if you instead intend to close the entity, and Delaware LLC annual tax and filing requirements for the related annual obligation.

Corporations and Other Entities

The registered agent requirement is not unique to LLCs. Delaware corporations, limited partnerships, and other filing entities must also maintain a Delaware registered agent under their own statutes, and many commercial agents serve all entity types. The core rule is the same: a physical Delaware registered office and an agent reachable there. If you are choosing an entity type, see what an LLC is and S-corp vs LLC, and remember the agent requirement applies whichever Delaware entity you pick.

The registered agent role also connects to the rest of your Delaware compliance. The agent is usually the party that receives and forwards your annual-tax notices, so a reliable agent indirectly helps you avoid the $200 late penalty on the flat $400 tax. Many owners bundle registered-agent service with the same provider that handles their formation and annual filings, which keeps every Delaware obligation flowing through one channel. Whatever you choose, the legal duty to maintain the agent rests with the LLC, not the provider - so if a provider fails, appointing a replacement promptly is your responsibility.
