Maine LLC Operating Agreement (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

A Maine LLC operating agreement is the internal contract among the members that sets out ownership percentages, management, voting, and how profits are shared. Maine does not require you to file it with the Secretary of State, but under the Maine Limited Liability Company Act (Title 31) it is the document that overrides the statutory default rules and governs how the LLC runs.

What a Maine LLC Operating Agreement Is

An operating agreement is the private, internal document that governs how a limited liability company is owned and run. It is a contract among the members (the owners) covering who owns what, who manages the business, how decisions are made, and how money moves. For a Maine LLC, it is the operating agreement - not the public formation filing - that controls the day-to-day and the relationships among owners.

It is separate from the Certificate of Formation you file to create the LLC. The certificate brings the entity into legal existence with the state; the operating agreement is kept privately and spells out the deal among the members. Think of the certificate as your birth certificate and the operating agreement as your rulebook.

See the national operating agreement guide for the general concept. The rest of this page focuses on how Maine treats the agreement and what a Maine LLC should include in it.

Is an Operating Agreement Required in Maine?

Maine law does not require you to file an operating agreement, and the Secretary of State does not collect or store it. In that narrow sense it is optional. But the Maine Limited Liability Company Act expressly recognizes the operating agreement and lets it govern the LLC's internal affairs, which makes having one highly advisable.

Without a written agreement, your LLC is governed entirely by the Act's default rules, which may not match what the owners actually intended - for example, on how profits are split or how a member can leave. A written agreement lets you replace those defaults with your own terms wherever the statute permits.

A written operating agreement also helps demonstrate that the LLC is a genuine, separate entity, which supports the liability shield. Banks, lenders, and investors routinely ask to see it, so even though Maine does not mandate one, you should have it before you open a bank account.

What to Include in the Agreement

A thorough Maine operating agreement typically covers the members and their ownership percentages; each member's capital contribution; how profits and losses are allocated and distributed; and voting rights and how decisions are made. These economic and control terms are the heart of the document.

It should also address management structure (member- or manager-managed), the authority to sign contracts and bind the LLC, meetings and record-keeping, and how new members are admitted. Getting these mechanics on paper prevents disputes later, when memories differ.

Finally, plan for change: include buy-sell or transfer provisions, what happens when a member dies or wants out, how the agreement can be amended, and dissolution procedures. Coordinating these with your EIN and tax elections keeps the paperwork consistent from the start.

Member-Managed vs Manager-Managed

One of the most important choices the agreement records is the management structure. In a member-managed LLC, the owners run the business directly and can typically bind the company - the default many small LLCs use. In a manager-managed LLC, the members appoint one or more managers (who may or may not be members) to run operations, while the members take a more passive, investor-like role.

The choice affects who has authority to sign contracts, open accounts, and make everyday decisions. Passive investors usually prefer manager-managed so they are not exposed to management duties, while owner-operators often choose member-managed for simplicity.

State your choice clearly in both the operating agreement and, where the form asks, the Certificate of Formation, so third parties know who can act for the LLC. Ambiguity here is a common source of disputes and of questions from banks.

Single-Member vs Multi-Member Agreements

Even a single-member LLC should have an operating agreement. It may feel unnecessary when one person owns everything, but the document helps prove the LLC is separate from its owner, which reinforces the liability shield, and it provides for succession if the owner dies or becomes incapacitated.

Multi-member agreements are more involved because they must resolve how co-owners share control and money: voting thresholds, deadlock procedures, capital calls, and what happens when an owner wants to sell or leave. These provisions are where a well-drafted agreement earns its keep.

In both cases, the agreement should track how the LLC is taxed - a single-member LLC is a disregarded entity by default, a multi-member LLC a partnership, and either can elect S-corporation status - so ownership and allocation terms line up with the tax return.

Maine's Default Rules Fill the Gaps

Where your operating agreement is silent, the Maine Limited Liability Company Act supplies default rules. These cover matters like voting, distributions, and members' rights and duties. The defaults are sensible general rules, but they are one-size-fits-all and may not reflect your particular deal.

The Act generally lets the operating agreement override many of these defaults, though certain provisions - such as the members' core fiduciary and good-faith obligations - cannot be eliminated entirely. Drafting your own terms is how you take control of the gaps the statute would otherwise fill.

Because the statute is the backstop, read your agreement against Title 31 to confirm your chosen terms are permitted and that you have addressed the points that matter most to your business. When in doubt, have a Maine attorney review it.

Adopting, Signing, and Updating the Agreement

To put the agreement in force, the members adopt and sign it, ideally at or soon after formation. Keep the signed original with your other company records - your Certificate of Formation, EIN confirmation, and licenses - and give each member a copy. Maine does not file it, so you are responsible for maintaining it.

Revisit the agreement whenever the business changes: a new member joins, ownership percentages shift, the management structure changes, or you make a new tax election. Amend it following the amendment procedure the agreement itself sets out, and have all members sign the amendment.

An operating agreement is a living document, not a one-time formality. Keeping it current - and consistent with your annual report and tax filings - is the simplest way to avoid internal disputes and to keep your liability protection intact.

Frequently Asked Questions

Is an operating agreement required for a Maine LLC?

No. Maine does not require you to file an operating agreement, and the Secretary of State does not collect one. However, the Maine Limited Liability Company Act recognizes the agreement and lets it govern the LLC, so having a written one is strongly recommended.

Do I file my Maine operating agreement with the state?

No. The operating agreement is a private, internal document that you keep with your company records. Only the Certificate of Formation is filed with the Maine Secretary of State to create the LLC.

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

It is not legally required, but it is strongly recommended. A written agreement for a one-owner LLC helps prove the business is a separate entity, reinforcing the liability shield, and provides for succession if the owner dies or is incapacitated.

What happens if my Maine LLC has no operating agreement?

The LLC is governed entirely by the default rules in the Maine Limited Liability Company Act. Those defaults may not match the owners' intentions on issues like profit splits, voting, or member exits, which is why a custom agreement is advisable.

Can the operating agreement override Maine's default LLC rules?

Generally yes. The Maine LLC Act lets the operating agreement replace many statutory defaults, though certain core obligations, such as good-faith and fiduciary duties, cannot be fully eliminated. Read your agreement against Title 31 to confirm.

What should a Maine operating agreement include?

Ownership percentages, capital contributions, profit and loss allocation, voting rights, management structure (member- or manager-managed), transfer and buy-sell provisions, and amendment and dissolution procedures.
