A Texas LLC operating agreement is the internal contract that sets who owns the company, who runs it, how profits are split, and what happens when a member leaves or the business closes. Texas does not require one, and you never file it with the Secretary of State. Without it, the default rules in the Texas Business Organizations Code decide those questions for you, and they rarely match what the owners want.
This guide explains the LLC operating agreement Texas owners need, whether the law actually requires one, the clauses that matter most, and how it differs from the oil and gas Joint Operating Agreement people often confuse it with.
What Is an LLC Operating Agreement in Texas?
An LLC operating agreement is the written contract among the members, or owners, of a limited liability company that governs how the business is owned, managed, and run. It is the rulebook for the inside of your company.
Texas uses its own vocabulary here. Most states and business owners call what the Texas Business Organizations Code (TBOC) calls a company agreement under Section 101.052 an operating agreement. The two terms mean the same thing, and well-drafted Texas agreements often say “Company Agreement (also called an Operating Agreement)” in the title to avoid confusion.
Under Texas law, a company agreement can technically be written, oral, or even implied by the members’ conduct. That flexibility is a trap. An oral or handshake agreement is nearly impossible to prove, and banks, lenders, investors, and courts will expect a signed document. A written operating agreement is the only version worth relying on.
One detail that surprises new owners: Section 101.052(g) provides that every member and manager is bound by the company agreement whether or not they actually signed it. The document controls the relationship the moment the members adopt it.
Is an Operating Agreement Required for a Texas LLC?
No. Texas does not legally require an LLC to adopt an operating agreement, and you never file one with the Secretary of State. You create the LLC by filing a Certificate of Formation (Form 205) with the state and paying the $300 filing fee. That filing doesn’t ask for an operating agreement.
But “not required” is very different from “not important.” The TBOC builds its entire LLC framework around the assumption that members will adopt an agreement, and it supplies default rules only for the topics you leave unaddressed. Skip the agreement, and Chapter 101 of the code governs your company by default.
Those defaults control things like:
- How profits and losses are allocated among members
- How members vote and what it takes to approve major decisions
- How and whether new members can be admitted
- What happens to a member’s interest on death, exit, or dispute
- How the company is dissolved and wound up
The problem is that the default rules are one-size-fits-all. They may split profits in a way you never intended, give a minority member veto power you never agreed to, or leave your family without a clear path if you pass away. Your operating agreement is your chance to override those defaults with terms that fit your actual business.
This applies even if you are the only owner. A single-member LLC in Texas still benefits from an operating agreement, because it reinforces the separation between you and the company that protects your personal assets, and because banks, title companies, and lenders routinely ask for one before they will open accounts or close deals. An operating agreement is one of the core legal documents every small business needs.
What Every Texas LLC Operating Agreement Should Cover
A strong operating agreement answers the questions that cause the most expensive fights later, before they ever come up. At minimum, an LLC operating agreement Texas owners adopt should address:
- Ownership and membership interests. Who owns what percentage, and what each member contributed to earn it.
- Capital contributions. The cash, property, or services each member put in, and whether members can be required to contribute more later.
- Management structure. Whether the LLC is member-managed (owners run it) or manager-managed (appointed managers run it), and the limits on each manager’s authority.
- Voting rights and thresholds. How votes are weighted and what percentage is needed for ordinary decisions versus major ones like selling the company or taking on debt.
- Profit and loss distributions. How money is split and when distributions are made, which will not always track ownership percentages.
- Transfer restrictions and buy-sell terms. Whether a member can sell or transfer an interest, and what happens on death, divorce, bankruptcy, or a member wanting out.
- Dissolution and winding up. The agreed process for closing the business and distributing what is left.
Two Texas-specific points are worth building in deliberately. First, under Section 101.053, the default rule is that a company agreement can be amended only if every member consents, so if you want a lower amendment threshold, you have to say so. Second, because members are bound whether or not they sign, collecting every owner’s signature is about proof and buy-in, not legal validity.
Terms that look standard can quietly shift control or money to one member. This is the kind of document worth having a business or corporate attorney draft or review, rather than pulling from a free template.
Operating Agreement vs. Joint Operating Agreement
Here is where the confusion starts. An LLC operating agreement and an oil and gas Joint Operating Agreement (JOA) both get shortened to “operating agreement,” but they are completely different contracts that do completely different jobs.
An LLC operating agreement governs the internal affairs of a single business entity: your LLC. A Joint Operating Agreement governs shared operations among several co-owners of an oil and gas property, naming one company as the operator to drill and produce for everyone’s joint account while the others, the non-operators, pay their proportionate share.
| Feature | LLC Operating Agreement | Joint Operating Agreement (JOA) |
| What it governs | Internal affairs of one LLC | Shared operations across co-owners of a well or field |
| Parties | Members (owners) of the LLC | Operator and non-operators (working-interest owners) |
| Standard framework | Texas Business Organizations Code, Section 101.052 | AAPL Form 610 model form (1977, 1982, 1989, 2015) |
| Filed with the state? | No | No |
| Core risk mechanism | Voting, distributions, transfer rules | Non-consent penalty and operator liability limits |
Most U.S. onshore JOAs start from the AAPL Form 610 Model Form Operating Agreement, and its most important clause is the non-consent penalty. When the operator proposes a new well, each party chooses to participate or to go non-consent. A non-consenting party pays nothing up front but forfeits its share of production until the consenting parties recover a penalty, commonly 300% of the drilling, completion, and equipping costs plus 100% of operating costs. Going non-consent protects you from paying for a dry hole, but it becomes an expensive choice when the well produces.
Standard JOA language also shields the operator from liability for ordinary mistakes, leaving it responsible to its partners usually only for gross negligence or willful misconduct. None of that has anything to do with how your LLC votes or splits profits.
If you own oil and gas interests through an LLC, you may well need both documents: an operating agreement for the entity, and a JOA for the shared drilling operations. Knowing which one you are looking at is the first step to protecting yourself. Our guide to how operators and non-operators share risk in a JOA breaks down that side in detail.

Conclusion
A Texas LLC operating agreement, called a company agreement under state law, is what turns a filing with the Secretary of State into a business with clear rules. It decides ownership, management, voting, distributions, and what happens when a member leaves. Without it, the default rules of the Texas Business Organizations Code decide for you.
Understanding those terms, and not confusing them with an oil and gas Joint Operating Agreement, puts you in a far stronger position. The Adcox Firm drafts, reviews, and explains Texas LLC operating agreements in plain language, so you know exactly how your company is run before you sign.
Frequently Asked Questions
Is an operating agreement required for a Texas LLC?
No. Texas does not legally require an LLC to have an operating agreement, and you never file one with the Secretary of State. You only file a Certificate of Formation to create the LLC. Still, without an agreement, the default rules of the Texas Business Organizations Code will govern your company.
What does Texas law call an LLC operating agreement?
Texas uses its own term. The Texas Business Organizations Code, in Section 101.052, calls it a company agreement rather than an operating agreement. The two mean the same thing. Many Texas documents use the phrase “company agreement (also called an operating agreement)” in the title to avoid any confusion.
Does a single-member LLC in Texas need an operating agreement?
Yes, in practice. Even with one owner, an operating agreement reinforces the legal separation between you and the company that protects your personal assets. Banks, lenders, and title companies also routinely request one before opening accounts or closing deals, so a single-member LLC should still adopt a written agreement.
Is an LLC operating agreement the same as a Joint Operating Agreement?
No. They share a name but do different jobs. An LLC operating agreement governs the internal affairs of one business entity. A Joint Operating Agreement governs shared oil and gas operations among co-owners, naming one operator and setting cost-sharing and non-consent penalties. If you own energy assets through an LLC, you may need both.
Should a lawyer review my Texas LLC operating agreement?
Yes. An operating agreement controls ownership, money, and control for the life of your business, and template versions often miss terms that matter. A business attorney can flag one-sided voting, distribution, or transfer language and tailor the agreement to your goals. The Adcox Firm drafts and reviews these agreements for Texas clients.
