Texas LLP Name Search and Naming Rules

A Texas LLP's name has to be distinguishable in the records of the Secretary of State from other registered entity names. Before you file your registration, check whether your proposed name — and its close variations — are clear.

Where to search

The state's name availability search runs through SOSDirect, the Secretary of State's online portal. There's a small per-search fee for availability checks. For general questions about how names are evaluated, the Secretary of State also publishes name filing FAQs.

Search smart

• Search your exact proposed name first.
• Then search close variations — swapping a word, changing singular to plural, adding or dropping "the" or "and."
• Look for names that sound similar even if spelled differently, since the state considers more than exact matches.

Why this matters before you file

If your name conflicts with an existing registered name, the Secretary of State can reject your registration. A rejection costs you time and, if you've already printed materials or built a brand around the name, real money. A few minutes of searching up front prevents a frustrating back-and-forth with the state.

Texas sets specific rules for what an LLP can be called. Getting them right the first time keeps your registration moving.

The required designator

Your LLP's legal name must include a phrase or abbreviation that identifies it as a limited liability partnership — "limited liability partnership," "L.L.P.," or "LLP." This isn't optional. It signals to anyone dealing with the firm that they're working with a registered partnership carrying the liability shield.

The distinguishability standard

Your name must be distinguishable in the state's records from other entity names already on file — not just other LLPs, but corporations, LLCs, LPs, and other registered entities. "Distinguishable" is a legal standard, and small differences alone (punctuation, spacing, or filler words) may not be enough to set your name apart.

Restricted and regulated words

• Words implying a government agency are off-limits or restricted.
• Words like bank, trust, or insurance typically require approval from the relevant Texas regulatory authority.
• Professional partnerships may face additional naming conventions set by their licensing board — for example, rules about how a professional firm's name must be composed.

Practical naming tips

Pick a name that's genuinely distinct, not one that leans on a tiny variation of an existing firm. A distinctive name is easier to register, easier to protect, and easier to build a brand around. If your ideal name is close to something already registered, it's usually better to adjust it now than to fight over distinguishability later.

If you've found an available name but you're not ready to file the registration yet, Texas lets you hold it.

Name reservation

You can file a name reservation with the Secretary of State to hold a name for a set period while you get everything else in order. A reservation doesn't register your LLP — it just prevents someone else from taking the name in the meantime. This is useful if you're still assembling partners, drafting your partnership agreement, or lining up financing but want to lock the name down.

What a reservation does and doesn't do

• It holds the name for the reservation period.
• It does not create the LLP or give you the liability shield — only the registration does that.
• It does not protect the name as a trademark; that's a separate area of law.

A word on trademarks

Clearing a name with the Secretary of State only means it's available to register as your entity name in Texas. It does not mean you have trademark rights to it, and it doesn't prevent someone in another state or a national brand from having rights that conflict with yours. If your firm's name is central to your brand, a trademark search — and possibly a registration — is a separate step worth considering with an attorney.

Sometimes the name you register your LLP under isn't the name you want to market to customers. Texas handles that through assumed name registrations.

When you need an assumed name

If your LLP will conduct business under a name different from its registered legal name, you file an assumed name certificate — Form 503 — with the Secretary of State. For example, if your firm is registered as "Alvarez & Chen Advisory, L.L.P." but you want to operate a division as "Lone Star Wealth Partners," you'd register that as an assumed name.

How assumed names work in Texas

• The assumed name certificate is filed with the Secretary of State for an entity like an LLP.
• An entity's assumed name registration in Texas can run for up to ten years before it needs renewal — a long runway compared with many states.
• You can hold more than one assumed name if the firm operates under several brands.

Assumed name isn't the same as availability

Registering an assumed name puts the name on the state's record for your firm, but it doesn't guarantee exclusive rights to it any more than your entity name does. Still, checking availability and registering the assumed name keeps you compliant and on the record when you operate under something other than your registered legal name.

How Mainstay Filing helps

When we handle your LLP registration, we check name availability as part of the process and flag any distinguishability issues before they cause a rejection. If you plan to operate under a different name, we can prepare the assumed name certificate too, so your firm's public and marketing names are both properly on file.
