Wyoming LLC Operating Agreement: What Law Says (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 20, 2026 · Last updated Aug 20, 2026

A Wyoming LLC operating agreement is the internal contract that governs the company. It is not filed with the Secretary of State and Wyoming does not require one, but W.S. 17-29-110 makes it the controlling document for member relations, management, voting, transfers, and distributions - subject to a short list of things it may not do.

What an Operating Agreement Is in Wyoming

An operating agreement is the internal contract among an LLC's members - and, under Wyoming law, between the members and the company itself. Wyoming never files it. The Secretary of State's records show the Articles of Organization, the registered agent, and the annual report; the operating agreement stays with the company. That privacy is one of the reasons Wyoming is popular with holding structures.

Privacy does not mean the document is informal. The Wyoming Limited Liability Company Act, W.S. 17-29-101 through 17-29-1105, treats the operating agreement as the primary source of governance and treats the statute as the fallback. Getting the agreement right is therefore how you control the outcome of most internal disputes.

What W.S. 17-29-110(a) Puts Under the Agreement

Section 17-29-110 is titled "Operating agreement; scope, function and limitations." Subsection (a) provides that, except as limited by subsections (b) and (c), the operating agreement governs all of the following:

That last catch-all is broad by design. Practically, it means that if the members write a rule and it does not run into subsection (c), the rule controls.

Silence Means the Statute Wins

W.S. 17-29-110(b) is one sentence and it is the reason to have an agreement at all: to the extent the operating agreement does not otherwise provide for a matter described in subsection (a), the chapter governs the matter. Every gap in your document is filled by a statutory default you did not choose.

Those defaults are reasonable general rules, but they are not tailored. Default rules on voting, distributions, transfer of interests, and dissociation may allocate control very differently from what a founding team assumes. Writing the agreement is how you replace defaults with intent.

The Ten Limits in 17-29-110(c)

Subsection (c) lists what an operating agreement shall not do. It cannot vary the LLC's capacity under 17-29-105 to sue and be sued in its own name. It cannot vary the law applicable under 17-29-106. It cannot vary the power of the court under 17-29-204. It cannot eliminate the contractual obligation of good faith and fair dealing under 17-29-409(d). It cannot unreasonably restrict the duties and rights stated in 17-29-410 - the provisions on member access to information. It cannot vary the power of a court to decree dissolution in the circumstances specified in 17-29-701(a)(iv) and (v). It cannot vary the requirement to wind up the company's business as specified in 17-29-702(a) and (b)(i). And it cannot unreasonably restrict the right of a member to maintain an action under article 9 of the chapter.

The pattern is consistent: Wyoming lets members rewrite their economic and governance deal almost entirely, but preserves the courts' role, minimum good faith, information rights, and orderly winding up. Drafting past those limits does not just fail - it can invalidate the clause while leaving the rest of the agreement intact.

Who Is Bound: 17-29-111

Section 17-29-111 answers the questions that trip people up. Subsection (a): a limited liability company is bound by and may enforce the operating agreement, whether or not the company has itself manifested assent. The LLC does not need to sign. Subsection (b): a person who becomes a member is deemed to assent to the operating agreement - an incoming member inherits the deal.

Subsection (c) covers timing. Two or more persons intending to become initial members may make an agreement providing that, upon formation, it becomes the operating agreement. And - the sentence that matters for solo owners - one person intending to become the initial member may assent to terms providing that upon formation those terms become the operating agreement.

Single-Member Wyoming LLCs

Owners of one-member companies often skip the agreement because there is no one to negotiate with. Wyoming's statute anticipates the single-member case and provides the mechanism anyway, and there are four practical reasons to use it. It evidences that the LLC is a separately governed entity, the central question when a creditor argues the company is the owner's alter ego. It states who may bind the company, which banks, landlords, and lenders ask about. It addresses death or incapacity, which is otherwise left to statutory defaults and probate. And it records capital contributions and distributions, keeping the owner/company line visible. See the national single-member LLC guide.

Amendments and Third Parties

Section 17-29-112 addresses the agreement's effect on outsiders. Among other things, an operating agreement may specify that its amendment requires the approval of a person who is not a party to the agreement, or the satisfaction of a condition - and an amendment adopted without that approval is ineffective. Lenders and investors use this to lock in protections that a later member vote cannot quietly undo. If you grant such a right, record it clearly, because the consequence of ignoring it is that the amendment simply does not take effect.

What to Put in the Document

A workable Wyoming operating agreement covers: the company's name, principal office, and registered agent; the members and their ownership percentages; capital contributions and whether additional contributions can be required; allocation of profits and losses and the timing of distributions; member-managed or manager-managed structure and the scope of manager authority; voting thresholds for ordinary and major decisions; transfer restrictions and any right of first refusal; what happens on a member's death, disability, withdrawal, or bankruptcy; buy-sell mechanics and valuation method; books, records, and member information rights; deadlock resolution; amendment procedure; and dissolution and winding up. Sign it, date it, and store it with your corporate records.

The Agreement in the Wider Wyoming Picture

The operating agreement is one of four things a Wyoming LLC needs to run cleanly. The others are a current filing with the Secretary of State - Articles of Organization and the annual report; a registered agent in Wyoming; and federal tax compliance, since Wyoming imposes no individual or corporate income tax and the federal layer is where most of the tax work happens. See how to form an LLC in Wyoming, registered agent requirements, and how to get an EIN.

One last caution: do not adopt a generic template written for another state. Wyoming's numbering, its good-faith provision, its information-rights section, and its winding-up rules are specific, and a clause that is enforceable in one state can collide with 17-29-110(c) here. Terms used above are defined in the glossary, and structure choices are compared in LLC vs corporation.

Frequently Asked Questions

Does Wyoming require an LLC operating agreement?

No. Wyoming does not require an operating agreement and never files one. But W.S. 17-29-110 makes the agreement the governing document for nearly every internal question, and 17-29-110(b) provides that where the agreement does not address a matter, the LLC Act governs instead. Without an agreement, you accept every statutory default.

What does W.S. 17-29-110 say an operating agreement governs?

Subsection (a) lists eight areas: relations among members and between members and the company; the rights and duties of a person acting as manager; the activities of the company and the conduct of those activities; the means and conditions for amending the agreement; management and voting rights of members; transferability of membership interests; distributions to members before dissolution; and all other aspects of managing the company.

What can a Wyoming operating agreement not do?

W.S. 17-29-110(c) sets limits. It cannot vary the company's capacity to sue and be sued in its own name, vary the applicable law under 17-29-106, vary the power of the court under 17-29-204, eliminate the contractual obligation of good faith and fair dealing under 17-29-409(d), unreasonably restrict the duties and rights stated in 17-29-410, vary a court's power to decree dissolution in specified circumstances, vary the winding-up requirement, or unreasonably restrict a member's right to bring an action under article 9.

Does a single-member Wyoming LLC need an operating agreement?

Legally no, practically yes. W.S. 17-29-111(c) expressly contemplates it: one person intending to become the initial member may assent to terms that become the operating agreement upon formation. For a solo owner the document evidences that the LLC is separately governed, states who may bind the company, and addresses succession on death or incapacity.

Is the LLC bound by an agreement it did not sign?

Yes. W.S. 17-29-111(a) provides that a limited liability company is bound by and may enforce the operating agreement whether or not the company has itself manifested assent to it. Subsection (b) adds that a person who becomes a member is deemed to assent to the operating agreement, so incoming members are bound by terms they never signed.

Can members agree on an operating agreement before forming the LLC?

Yes. W.S. 17-29-111(c) allows two or more persons intending to become the initial members to make an agreement providing that, upon formation of the company, the agreement becomes the operating agreement. The same subsection extends the mechanism to a single intended member assenting to terms in advance.
