Texas LLC Operating Agreement — Why You Need One

Texas calls the operating agreement a "company agreement" under the Texas Business Organizations Code. While Texas does not legally require you to have a written company agreement to form your LLC, operating without one means statutory defaults in the BOC govern your LLC — and those defaults may not match what you and your co-owners intend. This is one of the most important steps after filing your Certificate of Formation.

What an Operating Agreement Does

The operating agreement is a private, internal document (not filed with the state) that governs:

Texas-Specific Considerations

Why Texas defaults may not work for you:

Under the Texas Business Organizations Code, without a written company agreement, your LLC operates under the statutory default rules in the Texas Business Organizations Code. Key defaults that often surprise members:

Texas enforcement:

Texas courts strongly enforce operating agreements. Under the Texas Business Organizations Code, a properly drafted operating agreement supersedes statutory defaults.Community property implications:

Texas is a community property state. If a married person uses community funds to invest in an LLC, the non-member spouse may have a community property interest in the membership interest. A well-drafted operating agreement addresses this by:

Operating Agreement vs. Certificate of Formation

Topic Certificate of Formation Operating Agreement
Filed with state? Yes (Secretary of State) No (internal document)
Public record? Yes (on SOSDirect) No (private)
Creates the LLC? Yes No
Governs internal operations? Partially (management type) Yes (detailed rules)
Can be amended without state filing? No (requires Form 424, $150) Yes (follow your own amendment procedure)
Required by banks? Yes (for account opening) Often required (banks want to see authority)

Common Mistakes

  1. Skipping it for single-member LLCs — Without an operating agreement, courts may find it easier to "pierce the veil" and treat the LLC as the member's alter ego, defeating liability protection.
  2. Using a generic template without customization — Texas-specific provisions (community property, BOC default overrides) matter. A template from another state may miss these.
  3. Not addressing death or incapacity — If a member dies without succession provisions, the LLC may face dissolution or lengthy probate proceedings.
  4. Conflicting with Certificate of Formation — If your operating agreement says "member-managed" but your certificate says "manager-managed," the certificate controls for third-party interactions. Keep them consistent.

FAQ

Does Texas require filing the operating agreement with the state?

No. The operating agreement is a private document. You do not file it with the Secretary of State, Comptroller, or any other agency. Keep it with your business records and provide copies to members and your bank.

Can I create an operating agreement after forming my LLC?

Yes. You can adopt an operating agreement at any time. However, it is best practice to have one in place before the LLC begins operations — especially before taking on members, opening bank accounts, or entering contracts.

Can a single-member LLC have an operating agreement?

Absolutely, and it is strongly recommended. A single-member operating agreement: (1) reinforces the legal separation between you and your LLC for liability protection, (2) establishes management procedures, (3) defines what happens if you become incapacitated, and (4) is often required by banks to open a business account.

How do I amend the operating agreement?

Follow the amendment procedure specified in your operating agreement itself. Most agreements require written consent of members holding a majority (or specified supermajority) of membership interests. No state filing is needed — just update the document and have all required parties sign.

Do I need a lawyer to draft my operating agreement?

Not legally required, but recommended for multi-member LLCs with significant assets, unequal contributions, or complex management structures. For simple single-member or 50/50 two-member LLCs, a well-researched template specific to Texas can work.
