Operating Agreement: What It Is, Who Needs One, and What It Costs in 2026
An operating agreement is the contract an LLC's members adopt to settle who owns what, who can make which decisions, and how profit gets split. It is an internal document. It is not filed with your state, and it does not show up in any public record.
Most owners get told they need one and never get told whether their state actually requires it. Here is the short version: 44 states do not require one at all. Six require one by statute. Only one of those six requires it in writing, and that state also sets a deadline measured from your filing date.
Below you get the state by state answer with the statute behind each one, the nine parts a working agreement contains, the three ways to produce one, what each route costs in 2026, and what governs your company if you never sign anything.
Key Takeaways
- An operating agreement is internal. It is never filed with the state and is not public record.
- Alabama, California, Delaware, Maine, Missouri and New York require one by statute. The other 44 states do not.
- Only New York requires it in writing, and allows adoption up to 90 days after the articles of organization are filed.
- Without one, your state's default rules govern, and many of them split profit and voting equally regardless of what each member contributed.
- Costs run from $0 for a template to roughly $850 for attorney drafting. No state charges a filing fee for it.
What Is an Operating Agreement?
An operating agreement is the internal contract among an LLC's members that sets out who owns what, who decides what, and how money moves. It is not filed with the state and it is not public record. Delaware and Maine statutes call the same document a limited liability company agreement.
Formally it is a limited liability company operating agreement. Owners shorten that to an LLC agreement, and searches for a business operating agreement land in the same place. Four names, one document.
The reason an LLC operating agreement carries weight is not that it is filed anywhere, because it is not. It is that the agreement overrides the default rules in a state's LLC statute. Every state has a chapter of law that decides how an LLC runs when its members have not decided for themselves. Signing an agreement replaces those defaults with your own terms. Signing nothing leaves them in force.
Do I Need an Operating Agreement for My LLC?
In 44 states, no. Six require one by statute: Alabama, California, Delaware, Maine, Missouri and New York. Only New York's statute requires it in writing, and it allows adoption up to 90 days after your articles of organization are filed. The other five accept an agreement that is simply entered into or otherwise existing.
That distinction gets flattened everywhere else. Published lists of these states range from three to six, and most of them attach the word "written" to all of them. The statutes do not say that. Here is what each one actually says.
| State | Statute | What It Requires | Written Required? |
|---|---|---|---|
| Alabama | Ala. Code 10A-5A-2.01(d) | An agreement "shall be entered into" before, after, or at the time of filing | No |
| California | Corp. Code 17701.13(d)(5) | The LLC keeps a copy at its office "if in writing" | No |
| Delaware | 6 Del. C. 18-201(d) | An agreement "shall be entered into or otherwise existing" | No |
| Maine | 31 M.R.S. 1531(1)(B) | An agreement "must be entered into or otherwise existing" | No |
| Missouri | RSMo 347.081.1 | Members "shall adopt an operating agreement" | No |
| New York | N.Y. LLC Law 417 | Members "shall adopt a written operating agreement" | Yes |
Two things in that table are worth slowing down for.
California is the one most often cited and most often misread. The section quoted above is a records rule. It tells an LLC to keep a copy of its operating agreement at its designated office "if in writing". That phrase only makes sense if the agreement might not be written, so the citation does not support the claim it usually appears next to.
New York is the genuine outlier. Section 417(a) says members "shall adopt a written operating agreement", and section 417(c) allows that agreement to be entered into before, at the time of, or within ninety days after the articles of organization are filed. If you start an LLC in New York, the clock starts on your filing date.
Required and worth having are different questions. The next three sections deal with the second one.
What Does an Operating Agreement Look Like?
A typical LLC operating agreement runs 10 to 20 pages across nine standard parts: business details, ownership percentages, management structure, capital contributions, tax classification, voting thresholds, meetings, transfer of ownership interest, and dissolution with dispute resolution. The order varies by drafter. Those nine subjects appear in nearly every version.
- Business details. Legal name, principal office, purpose, registered agent, state and date of formation.
- Ownership. Each member's name and their interest, as a percentage or as units.
- Management. Member managed, where the owners run it, or manager managed, where a named manager does.
- Capital contributions. What each member put in, whether cash, property, or services. A loan to the company is normally not a contribution.
- Tax classification. The IRS default is a disregarded entity for one member and a partnership for two or more. Anything else is an election.
- Decision making. The threshold for a decision: a simple majority above 50%, a supermajority at two thirds or three quarters, or unanimous consent.
- Meetings and voting. How a meeting gets called, how votes are cast, how they are recorded.
- Transfer of interest. Whether a member can sell to an outsider, and whether the others get first refusal.
- Exit and disputes. Buyout terms, what happens on a member's death, and the path for a dispute, usually negotiation, then mediation, then arbitration.
The 10 to 20 page range describes market practice, not a legal minimum. A single owner with no outside money can be served by something far shorter.
How to Write an Operating Agreement
Three routes. Fill in a free template, which suits a single owner or an even split. Fill in a template and pay a lawyer to review it. Or have one drafted from scratch, which is the right call for uneven contributions, outside investors, real property, or any buyout terms.
A free LLC operating agreement template is a reasonable starting point when the facts are simple. Reading a sample LLC operating agreement first is worth the five minutes, and most are published as a downloadable LLC operating agreement PDF, so you can see the shape of the document before committing to anything.
The middle route rarely gets named and is often the best value: fill in the template yourself, then pay for an hour of review. You are paying for judgment on the parts that matter rather than for typing.
One warning about templates is worth more than the rest. Most stock forms allocate profit strictly in line with ownership percentage. If your deal is that one member put in the money and another puts in the hours, a template will quietly overwrite that arrangement with a split nobody agreed to. That single clause is the most common reason a multi member agreement has to be redone.
Whichever route fits, the agreement belongs to a company that exists. Form your LLC with FormationHub, then adopt the agreement that governs it.
How Much Does an Operating Agreement Cost?
Between nothing and roughly $850. A template costs $0. Marketplace data from US lawyers, updated August 2026, puts the average flat fee at about $850 to draft one from scratch and about $560 to review an agreement you have already filled in. No state charges a filing fee for it.
The full operating agreement cost picture is a ladder rather than a price:
- Template, $0. Suits a single owner or an even split with no outside money.
- Template plus review, roughly $560 on average. Suits most multi member LLCs.
- Drafted from scratch, roughly $850 on average. Suits uneven splits, property, investors, or staged buyouts.
Those averages come from completed projects across all US states, so a complex agreement in a high cost market runs above them. The number that does not move is the state's: zero. Unlike your articles of organization, this document carries no filing fee anywhere, because it never goes to the state.
What Happens If You Do Not Have One
Your state's default rules run your company. They are written to be neutral, which is exactly the problem. In many states the defaults split profit and voting power equally among members regardless of what each one contributed. A member who funded 80% of the business can find the statute treating them as an equal to a member who funded 20%.
The agreement also carries evidentiary weight. It documents that the LLC is a separate entity with its own governance rather than an extension of its owner, which is one of the things a court looks at if the separation is ever challenged. It is evidence, not a guarantee.
There is a practical reason too. Banks routinely ask for the operating agreement when you open a business account, because it is the document that shows who owns the company and who is authorized to act for it. A multi member LLC that arrives without one tends to stall at that counter.
Multi Member LLCs and the Documents People Confuse It With
For a single owner, an operating agreement is mostly good hygiene, and the single member LLC operating agreement has its own shorter shape. A multi member LLC operating agreement is a different animal. It is the document that decides arguments about money, and the arguments it prevents are the expensive ones: what happens when contributions are uneven, when a vote deadlocks, when someone wants out. The differences between single member and multi member LLCs run deeper than member count.
Two documents get mixed up with it constantly.
Your articles of organization are what you file with the state to bring the LLC into existence, and they are public. The operating agreement is what you sign afterward to govern it, and it stays private. The distinction between articles of organization and an operating agreement is filing versus governing.
The partnership agreement vs operating agreement question is simpler than it looks: same job, different entity. A partnership agreement governs a partnership. An operating agreement governs an LLC.
