Get Updates on New Texas Business Guides
Texas law doesn't require an LLC to have an operating agreement — which is exactly why so many ownership disputes trace back to never having one. This guide covers what to include, where businesses go wrong, and how bylaws work for corporations.
Quick Answer
- Texas law generally does not require LLCs to adopt a written operating agreement.
- Without one, the Texas Business Organizations Code's default rules govern the company instead.
- An operating agreement defines management, voting rights, profit distributions, and exit procedures.
- Corporations use bylaws, not operating agreements, to govern internal affairs.
- Neither document is filed with the Texas Secretary of State — both are kept as internal company records.
Key Takeaways
- An operating agreement is not legally required for a Texas LLC, but its absence means default statutory rules apply.
- Both multi-member and single-member LLCs benefit from having one in place.
- A signed agreement can support — though not guarantee — the LLC's liability shield.
- Key provisions include management structure, capital contributions, distributions, voting, transfers, and dissolution.
- Corporations rely on bylaws, adopted by the board of directors, for equivalent internal governance.
- Common mistakes include using generic templates, never signing the document, and failing to update it.
- Buy-sell provisions are frequently the most important — and most overlooked — section of the agreement.
- Neither operating agreements nor bylaws are filed with or made public by the state.
- An attorney can tailor these documents to your specific ownership structure and goals.
1. What Is an LLC Operating Agreement?
An operating agreement, referred to in the Texas Business Organizations Code (BOC) as a "company agreement," is the governing document that sets out how a limited liability company will be owned and run. Texas defines it broadly enough to cover more than a single signed document.
A company agreement is "any agreement, written, implied, or oral, of the members" concerning the affairs of the LLC.Tex. Bus. Orgs. Code § 101.001(1)
In practice, that means an unwritten understanding between members could technically qualify — but an implied or oral "agreement" is nearly impossible to enforce with any precision. A written, signed operating agreement is what actually protects the business when memories diverge or a dispute lands in court.
2. Is an Operating Agreement Legally Required in Texas?
No. Texas is one of the majority of states that does not require an LLC to adopt a written operating agreement as a condition of formation. An LLC becomes a legal entity once its certificate of formation is filed with the Texas Secretary of State — no operating agreement is required for that filing to be accepted.
3. Why You Should Have One Anyway
Even though it isn't legally mandated, an operating agreement serves several practical functions that matter well beyond a state filing requirement:
- Supporting limited liability protection. Courts weighing whether to disregard an LLC's liability shield look at whether the company was actually run as a separate, legitimate business entity.
- Preventing default statutory rules from applying. Without an agreement, the BOC's default provisions govern the company instead of the members' actual intentions.
- Clarifying member rights and responsibilities. It removes ambiguity about who can make decisions, how profits are shared, and what happens if a member wants out.
- Supporting banking and financing needs. Banks and lenders frequently request a copy before opening accounts or extending credit.
4. What Happens Without One: Default Rules
When an LLC has no operating agreement, the Texas Business Organizations Code fills the gap. Certain provisions of the BOC cannot be waived or modified even if members later try to agree otherwise.
Specific statutory provisions "may not be waived or modified in the company agreement" of a Texas LLC, regardless of member consent.Tex. Bus. Orgs. Code § 101.054
Risk
Without a company agreement addressing management, profit allocation, and exit terms, an LLC is left to whatever the BOC's general default rules and general partnership-style assumptions supply — which rarely match what unequal contributors or specialized management structures actually intended.
5. Key Provisions to Include
A comprehensive Texas LLC operating agreement typically addresses:
- Management structure — member-managed vs. manager-managed
- Capital contributions — what each member contributed and future funding obligations
- Profit and loss distributions — how and when money is allocated among members
- Voting rights — what requires unanimous consent vs. majority approval
- Transfer restrictions — limits on selling or assigning membership interests
- Dissolution procedures — the process for winding down the business
Management Structure
A Texas LLC can be structured as member-managed, where all members participate directly in running the business, or manager-managed, where members appoint one or more managers (who may or may not also be members) to handle day-to-day operations.
| Structure | Who Runs the Business | Best Suited For |
|---|---|---|
| Member-Managed | All members jointly | Small LLCs with active, hands-on owners |
| Manager-Managed | Appointed manager(s) | LLCs with passive investors or outside management |
7. Capital Contributions
The agreement should document what each member contributed to form the LLC — cash, property, services, or a combination — and whether members are obligated to contribute additional capital in the future. Texas law holds members to enforceable contribution promises regardless of later changes in circumstance.
8. Profit and Loss Distributions
Distribution provisions determine how and when profits (and losses) are allocated among members. Absent an agreement stating otherwise, default rules may allocate distributions in ways that don't reflect unequal capital contributions or unequal work performed by the members.
9. Voting Rights and Decision-Making
The agreement should specify which decisions require unanimous member consent, which require majority or supermajority approval, and which can be made unilaterally by a manager. Common items requiring heightened approval include admitting new members, incurring significant debt, and amending the agreement itself.
A company agreement "may be amended only if each member of the company consents to the amendment," unless the agreement provides otherwise.Tex. Bus. Orgs. Code § 101.053
10. Transfer Restrictions and Buy-Sell Provisions
Transfer restrictions limit a member's ability to sell, assign, or pledge their membership interest without the consent of other members or the company. Related buy-sell provisions establish a clear process — and often a valuation method — for what happens when a member wants to exit, becomes incapacitated, or passes away.
Better Practice
Pair transfer restrictions with a defined valuation method (such as a formula or independent appraisal) agreed to in advance. Waiting until a dispute arises to negotiate a valuation almost always favors whichever member has more leverage at that moment.
11. Dissolution Procedures
Dissolution provisions describe the events that trigger winding down the LLC (such as a member vote, a specified date, or a triggering event) and the order in which company assets are distributed — typically creditors first, then members according to their interests.
12. Single-Member vs. Multi-Member LLCs
Multi-member LLCs need detailed provisions governing decision-making authority, dispute resolution between members, and buyout mechanisms if a member leaves, becomes incapacitated, or passes away. Without these provisions, disagreements can escalate quickly and expensively.
Single-member LLCs still benefit significantly from an operating agreement, primarily to reinforce the separateness of the business from the owner for liability-protection purposes, and to establish clear operating procedures that can matter for banking, financing, or a future sale of the business.
A company agreement of an LLC "having only one member is not unenforceable because only one person is a party" to it.Tex. Bus. Orgs. Code § 101.001(1)
13. Corporate Bylaws: The Corporation's Equivalent
Corporations don't use operating agreements — they rely on bylaws to govern internal operations. Under Texas law, the board of directors of a corporation is required to adopt initial bylaws.
"The board of directors of a corporation shall adopt initial bylaws."Tex. Bus. Orgs. Code § 21.057(a)
Well-drafted bylaws typically cover:
- Director and officer roles — duties, election procedures, and removal processes
- Shareholder meeting requirements — notice, quorum, and voting procedures
- Stock issuance procedures — how and when new shares can be issued
- Amendment processes — how the bylaws themselves can be changed
LLC Operating Agreement vs. Corporate Bylaws
| Feature | LLC Operating Agreement | Corporate Bylaws |
|---|---|---|
| Required by Texas law? | No | Yes — board must adopt initial bylaws |
| Filed with the state? | No | No |
| Adopted by | Members | Board of directors (shareholders may also have authority) |
| Governs | LLC members and managers | Directors, officers, and shareholders |
| Amendment authority | Set by the agreement (often unanimous consent) | Board or shareholders, per Section 21.058 |
14. Operating Agreements and the LLC Liability Shield
A written operating agreement can help demonstrate that members intended to operate the LLC as a separate legal entity, although courts typically consider many other factors when evaluating whether to disregard an LLC's liability protection.
15. Common Operating Agreement Mistakes
Even businesses that recognize the value of an operating agreement often undermine it through avoidable mistakes.
Mistake
Using a generic online template
Templates that aren't tailored to Texas law or the business's specific ownership structure often miss provisions that matter most for that company.
Mistake
Never actually signing the agreement
An unsigned draft carries little weight if a dispute arises and a court has to determine what the members actually agreed to.
Mistake
Failing to update it after ownership changes
A new member joining or an existing member's interest being transferred should trigger a review and, if needed, an amendment.
Mistake
Ignoring buy-sell provisions
Leaving no clear process for what happens if a member wants to exit, dies, or becomes incapacitated is one of the most common — and costliest — omissions.
Mistake
Omitting dispute-resolution procedures
Without a defined process, a manageable disagreement between members can turn into expensive litigation.
Mistake
Giving members unclear voting rights
Ambiguous approval thresholds create deadlock exactly when a decision needs to be made quickly.
Mistake
Not addressing tax elections and allocations
Failing to coordinate the agreement with the LLC's tax classification and allocation method can create mismatches between what members expect and what a K-1 reports.
Mistake
Overlooking life events like divorce or bankruptcy
Without provisions addressing a member's divorce, bankruptcy, or death, an unintended third party — such as an ex-spouse's estate or a creditor — may end up with a claim on the membership interest.

17. Frequently Asked Questions
Is an operating agreement required in Texas?
No. Texas law does not require LLCs to adopt an operating agreement, but the absence of one means default statutory rules govern the business instead.
Does a single-member LLC need an operating agreement?
It's not required, but it's still recommended. A single-member operating agreement helps reinforce the separateness of the business from its owner and can matter for banking, financing, or a future sale.
Do I file my operating agreement with the state?
No. Operating agreements are internal governance documents and are not filed with the Texas Secretary of State.
Can an operating agreement be changed?
Yes. Under Section 101.053 of the Texas Business Organizations Code, a company agreement may generally be amended only if each member consents, unless the agreement itself sets a different approval threshold.
Who should sign the operating agreement?
Generally, all members of the LLC should sign, along with any manager if the company is manager-managed.
Are operating agreements public?
No. Unlike formation documents filed with the state, operating agreements are private and are not part of the public record.
What happens if an LLC doesn't have one?
The LLC is governed by the default rules in the Texas Business Organizations Code, which may not reflect the members' actual intentions regarding management, profit sharing, or exit procedures.
Are bylaws filed with the Secretary of State?
No. Like operating agreements, corporate bylaws are internal governance documents and are not filed with the state.
What's the difference between an operating agreement and a certificate of formation?
The certificate of formation is the public document filed with the Texas Secretary of State to create the LLC. The operating agreement is a private, internal document that governs how the members run the company day to day.
Does Texas require corporate bylaws?
Yes. Under Section 21.057 of the Texas Business Organizations Code, a corporation's board of directors is required to adopt initial bylaws, though the specific content is largely left to the corporation to determine.
