What a Maryland Resident Agent Is

A resident agent (some states call it a registered agent) is the person or entity your Maryland LLC designates to receive service of process - lawsuits and legal papers - plus tax notices and official correspondence from the state. The agent is the LLC's reliable, public point of contact so that anyone, including a court, can reach the business at a known Maryland address. This is the Maryland application of the national registered agent concept.

Maryland requires the agent because an LLC is a legal person that can sue and be sued; the state and the courts need a fixed place to deliver documents. Naming the resident agent is a required field in the Articles of Organization, so you must line one up before you form the LLC.

The term "resident agent" is Maryland's label for what most states call a registered agent, and what older documents sometimes call an agent for service of process. The role is the same: a reliable Maryland address where legal papers can always be delivered. Because the LLC's owners may work from home, travel, or live out of state, the resident agent gives courts and the state one dependable point of contact that does not move when the business does.

The Legal Requirement: § 4A-210

The requirement is set by Maryland Corporations & Associations Article § 4A-210, part of the Maryland Limited Liability Company Act. The statute states that each limited liability company shall have a principal office in Maryland and a resident agent. The obligation is continuous: the LLC must maintain both from the moment SDAT accepts its Articles of Organization until the LLC is cancelled or dissolved.

The statute pairs two distinct requirements. The principal office is the LLC's main Maryland address of record; the resident agent is the person or entity at a Maryland address who accepts service. They can be the same address, but they are separate fields on the Articles of Organization, and both must be kept current. Section 4A-210 also spells out how to designate or change the agent - by filing a signed statement with SDAT - and how a resident agent may resign, which is covered below. Because the duty flows directly from the statute, it cannot be waived by the operating agreement or by agreement among members.

The same section governs how you designate or change the agent - by filing a signed statement with SDAT - and what happens when an agent resigns. Because the duty is statutory, an LLC cannot waive it or operate without an agent, even temporarily. For the wider context of Maryland formation, see how to form an LLC in Maryland.

Who Can Serve as a Maryland Resident Agent

Under Maryland law, a resident agent must be one of the following, with a physical Maryland street address that is not merely a post office box:

Eligible agent	Conditions
An individual	Must be a Maryland resident and have a Maryland street address
A Maryland corporation	Must be a corporation formed in Maryland (including commercial agent companies)
Yourself, a member, or a manager	Allowed if you are a Maryland resident with a Maryland street address
A commercial resident agent service	A qualified Maryland entity that provides agent service for a fee

The agent must consent to accept service of process. Keep a signed consent with your records even though it is not filed separately. The agent must be available at the listed Maryland address during normal business hours to receive documents. Note that an out-of-state individual cannot serve as a Maryland resident agent; residency in Maryland (for an individual) or Maryland incorporation (for an entity) is the threshold requirement, which is why owners based outside Maryland almost always retain an in-state commercial agent.

Being Your Own Resident Agent vs. Hiring a Service

You can act as your own resident agent for free if you are a Maryland resident with a physical Maryland street address where you can reliably receive legal papers during business hours. This is the cheapest option and common for owner-operated LLCs based in Maryland.

Many owners instead hire a commercial resident agent service. Reasons include: you live outside Maryland, you work from a location where being served a lawsuit in front of customers is awkward, you want your home address off the public record, or you travel and cannot guarantee business-hours coverage. A commercial service charges an annual fee (set by the provider, not the state). Either way, the state requirement is the same; only convenience and privacy differ. See the national registered agent overview to weigh the trade-offs.

How to Change a Maryland Resident Agent

To change your resident agent or your principal office, file a Resolution to Change Resident Agent and/or Principal Office with SDAT. The filing fee is $25. If you file online through Maryland Business Express, the mandatory $50 expedited fee and a 3% technology fee also apply. The incoming agent must consent to the appointment.

Update the agent promptly whenever your commercial provider changes, your agent moves out of Maryland, or an individual agent stops being available. An out-of-date agent record is a common reason LLCs miss a lawsuit or a state notice. You can confirm your current agent on file through the SDAT business entity search.

Resignation and Vacancy

Under § 4A-210, a resident agent may resign by filing with SDAT. If the LLC has already appointed a successor agent, the resignation is effective when filed. If no successor has been appointed, the resignation takes effect 10 days after it is filed with SDAT - a window that gives the LLC time to name a replacement. Operating with a vacant resident agent position is a compliance failure that should be cured immediately by filing the change with a new, consenting agent.

Consequences of Not Maintaining an Agent

Failing to keep a resident agent and principal office has real costs. An LLC that lets its agent lapse can fall out of good standing with SDAT, which banks, lenders, and buyers check before doing business. If the failure continues alongside missed Annual Reports, the LLC can have its right to do business forfeited, and returning to good standing requires filing Articles of Reinstatement and clearing what is owed.

Beyond compliance, a missing or unreachable agent means a lawsuit can proceed without the LLC's knowledge, potentially leading to a default judgment. Keeping a current, reachable resident agent is inexpensive insurance against both outcomes. When you eventually close the business, the agent stays in place until you file Articles of Cancellation.

Address, Privacy, and Practical Tips

The resident agent's Maryland street address becomes part of the LLC's public record with SDAT, searchable by anyone. If you serve as your own agent from home, your home address is public. Many home-based owners hire a commercial resident agent specifically to keep their residence off the public record and to avoid being handed a lawsuit in front of family or customers. Whichever route you choose, make sure the address is one where someone is present during normal business hours, since service of process is time-sensitive and a missed delivery can lead to a default judgment. A commercial service typically scans incoming documents and forwards them the same day, which is one reason out-of-state owners and busy operators prefer them despite the annual fee - the cost buys reliable, business-hours coverage that a traveling owner cannot always guarantee in person.

A few practical habits keep the requirement painless: use an address you will keep for years, not a short-term rental; if you use a commercial service, calendar its renewal so coverage never lapses; and update SDAT immediately if your agent moves, resigns, or changes. Confirm the agent shown in the SDAT business entity search matches reality at least once a year, ideally when you file your $300 Annual Report. Treating the agent as a set-and-forget line item is the most common way LLCs end up out of compliance without realizing it.
