Registered Agent Requirements for a Texas LLC

A registered agent is the person or company your Texas LLC names to receive legal papers and official mail on its behalf. In the Business Organizations Code the role is tied to a "registered office" — the physical Texas address where the agent can be reached. The agent is the fixed, findable point of contact so that if someone sues your LLC or the state needs to reach it, there's a known address where documents can be delivered in person.

Every domestic LLC has to name a registered agent at formation, on the Certificate of Formation, and keep one continuously for the life of the company. It's not a one-time box to check — an LLC without a valid agent is out of compliance, no matter how current everything else is.

What the agent actually receives

• Service of process — lawsuits, summonses, subpoenas, and citations. This is the core function: if your LLC is sued, the plaintiff serves the registered agent.
• State correspondence — notices from the Secretary of State, including anything affecting the entity's status.
• Tax and compliance notices — correspondence tied to the Comptroller's franchise tax and forfeiture warnings.

The agent's job is to accept these promptly and get them to you fast. A missed lawsuit doesn't pause because you never saw it — a default judgment can be entered against a company that failed to respond, which is precisely why the reliability of the agent matters.

Texas sets specific, non-negotiable requirements for who and what can serve.

The requirements

• A physical Texas street address. The registered office must be a real street address in Texas. A P.O. box alone does not qualify, because process has to be capable of being hand-delivered.
• Availability during business hours. Someone must be present at that address during ordinary business hours to accept documents in person.
• Consent to serve. Texas requires the agent to consent to the appointment. The state provides Form 401-A as the written consent; you keep it in your records. Listing someone as your agent without their agreement is not permitted.
• An eligible party. The agent can be an individual resident of Texas or a business entity authorized to do business in Texas. Notably, the LLC cannot serve as its own registered agent — a member or manager can, in their individual capacity, but the company itself cannot.

The registered office versus the principal office

Don't confuse the two. The registered office is the agent's Texas address where legal service happens; it must be staffed during business hours. The principal office is where the business is actually run and can be anywhere, including out of state. They can be the same address, but they don't have to be, and they serve different purposes.

Texas lets you be your own registered agent, and for some owners that's fine. For others it creates problems they don't anticipate. Here's the honest trade-off.

Being your own agent

It costs nothing extra, and if you have a stable Texas street address and you're reliably there during business hours, it works. The downsides are real, though:

• Your address goes public. The registered office is part of the SOS record, which is searchable and indexed by search engines. If you use your home, your home address is now public.
• You have to be there. Process must be deliverable during business hours. If you're on a job site, traveling, or your hours are irregular, you can miss a delivery — and missing a served lawsuit has consequences.
• You get served in front of people. A process server can show up at your listed address, potentially in front of customers or family. A commercial agent absorbs that.

Hiring a commercial registered agent

A commercial service exists to solve exactly those problems. It puts its own professional address on the public record, keeps staff available every business day, scans and forwards what arrives, and typically reminds you about the franchise deadline. For owners who work from home, run a mobile business, or simply don't want to be tethered to an address during business hours, the cost is usually worth it.

The privacy angle

For many Texas owners the deciding factor is privacy. The registered office is permanently searchable. Once your home address is in that database, it's effectively public forever, and it's tied to your name and your business. A commercial agent keeps that link out of the public record entirely.

Agents change. People move, resign, or you switch to a service — all routine, as long as you handle the paperwork.

To change agents

File a statement of change of registered agent or registered office with the Secretary of State. Until that filing is processed, the state and the courts still treat your old agent and old address as valid — which means service could go somewhere you're no longer watching. If you're switching to a commercial agent, they usually prepare and file the change for you.

If your agent resigns

A registered agent can resign, and when they do, the SOS notifies the LLC. From that point you have a limited window to name a replacement. Let the role sit empty and your LLC drifts out of compliance, which puts your standing at risk.

Why a lapse is dangerous

An LLC without a valid registered agent can be flagged by the state, and worse, can be sued without any real chance to defend itself — if there's no reachable agent, service can proceed by other means and a judgment can land while you're unaware. Keeping the agent current is one of the cheapest, highest-leverage pieces of compliance you have.

When you form with Mainstay Filing, registered agent service is included. We provide a compliant Texas registered office, so your home or business address stays off the public SOS record, and we maintain availability during business hours so nothing served on your company gets missed.

When documents arrive — a lawsuit, a state notice, a Comptroller letter — we log them and forward them to you promptly, so you have time to act. We also keep an eye on the franchise tax deadline and can prompt you before May 15 so the Public Information Report doesn't slip. If you already have an LLC and just want to move your agent service over, we prepare and file the change of registered agent with the Secretary of State for you.

We're a filing and agent service, not a law firm — we don't give legal advice on how to respond to what gets served. What we do is make sure the documents reach you quickly and that your registered office is always valid and in good standing.
