Missouri Is One of the Few States That Actually Requires One
Most state limited liability company acts say members may adopt an operating agreement. Missouri says something different. Section 347.081.1 of the Revised Statutes reads: "The member or members of a limited liability company shall adopt an operating agreement containing such provisions as such member or members may deem appropriate, subject only to the provisions of sections 347.010 to 347.187 and other law." Missouri sits with California, Delaware, Maine and New York on the short list of states whose statute uses a mandatory verb.
The obligation has no penalty attached. Section 347.081 names no fine, no filing and no consequence for skipping it, which is why so many Missouri companies quietly ignore it. The consequence arrives elsewhere in chapter 347, and it is much worse than a fine: section 347.113.1 defines who counts as a member by reference to the operating agreement. Without the document, the question of who owns the company has no clean statutory answer.
What chapter 347 supplies where the agreement is silent
Money splits in an order that surprises founders. Section 347.101.2 pays distributions first in proportion to cash and other contributions until each member has been returned their contribution, and second, equally. A member who put in $200,000 and a member who put in nothing end up sharing the ongoing profit down the middle once the capital has come back. Managers, where the articles vest management in them and the agreement does not say how they are chosen, are elected by a majority by number of the members under section 347.079.2, not by a majority of the capital. And section 347.121.1 lets any member walk on 90 days prior written notice.
The single owner rule is stricter, not looser
Section 347.015(13) defines an operating agreement as "any valid agreement or agreements, written or oral, among all members, or written declaration by the sole member". Read the two halves. A multi-member Missouri company may have an oral agreement. A single-member Missouri company cannot: the only form the definition recognises for a sole owner is a written declaration. So a one owner Missouri limited liability company that has never written anything down does not have an operating agreement at all, while section 347.081.1 says it shall have one. Our single-member LLC guide covers what that declaration should contain.
Reading Section 347.081 Carefully
The section has four subsections and each one matters. Subsection 1 imposes the duty and then lists eight things the agreement may cover, including whether management is vested in members, managers or other persons, classes of members with different rights, the division of voting rights "on a per capita or other basis", transfer restrictions, allocations, and tax elections. Subsection 2 states the policy of sections 347.010 to 347.187 is to give the maximum effect to the principle of freedom of contract and to the enforceability of operating agreements. Subsection 3 makes the agreement enforceable at law or in equity by any member. Subsection 4 preserves any otherwise valid agreement among members.
Notice what subsection 1 does not do. It does not require a particular form, a filing, a notarisation or a signature block. It does not say what happens if the members ignore it. The enforcement mechanism is contractual: a member who wants a term enforced has subsection 3, and a member who has no document has nothing to enforce.
There is no state fee, because there is no filing. Missouri's Business Services Division records the articles of organization and later charter documents, and the operating agreement is not among them. The Missouri filings that do carry a fee are formation, amendment of the articles, termination and, if the entity is administratively dissolved, rescission.
What Belongs in a Missouri Operating Agreement
Missouri operating agreement at a glance
| Item | Missouri position |
|---|---|
| Statutory requirement | Yes. RSMo § 347.081.1 says members shall adopt one |
| Written required | Oral is permitted among all members; a sole member needs a written declaration under § 347.015(13) |
| Filed with the State | No. It is not part of any Secretary of State filing |
| State fee to adopt | $0, because nothing is filed |
| Governing act | Missouri Limited Liability Company Act, RSMo §§ 347.010 to 347.187 |
| Custom drafting | $99 flat |
Ten clauses carry the load. In Missouri several of them are load bearing in a way they are not elsewhere, because chapter 347 routes membership, management and amendment through the agreement.
1. Who the members are, which the statute makes the agreement decide
Section 347.113.1 says a person is a member at formation if identified as a member in, and a party to, the operating agreement. Section 347.113.2 admits later members the same way, or, where the agreement is silent, on the written consent of all members. Name every member and every percentage, and update the schedule when it changes.
2. Contributions and the order in which they come back
Record cash, property and services with values, and record them in the section 347.091 books, because section 347.101.2 uses those values to return capital before anything is shared equally. Say whether further capital calls are permitted and what happens to a member who does not fund one.
3. Management, which Missouri puts in the articles first
Section 347.079.1 is unusual: the articles of organization shall provide how management is vested and who has authority to manage. The agreement then restricts or enlarges those rights. If the articles vest management in managers, section 347.079.2 lets the agreement name them, and only if the agreement is silent do you fall back on a vote of a majority by number of the members.
4. Voting weights and the six unanimous items
Section 347.081.1(3) expressly allows voting rights to be divided on a per capita or other basis, so choose. Then read section 347.079.3, which requires unanimous member consent, except as the agreement provides, to amend a written operating agreement, issue an interest and admit a member, approve a merger, switch between member and manager management, or authorise a transaction outside the stated purpose or the usual course of business.
5. Distributions, and displacing the return then split equally rule
Section 347.101.1 pays distributions at the times the agreement specifies, or if it does not, when a majority of the authorised persons approve. Section 347.101.2 then sets the default order described above. Write the split you actually intend, add a tax distribution, and state the reserve that has to be funded first.
6. Transfers, pledges and who can become a member
Section 347.115.1 makes the interest personal property, assignable in whole or in part except as the agreement provides, and confirms that a pledge does not by itself end membership. An assignee gets distributions only, never management rights, unless admitted under section 347.113. Add consent, a right of first refusal and a mandatory offer on death, divorce or bankruptcy.
7. Withdrawal, the 90 day notice and the dissolution it can trigger
Section 347.121.1 allows withdrawal at the time or on the events specified in writing in the agreement, or at any time on 90 days prior written notice. If the withdrawal breaches a written provision, the company may recover damages and offset them against what is otherwise distributable. Section 347.121.3 leaves the departed member with only assignee rights.
8. Dissolution triggers, including the one that follows a departure
Section 347.137.1(3) is the clause to override: except as the agreement provides, an event of withdrawal dissolves the company if a majority by number of the remaining members agree within 90 days. Section 347.137.1(4) keeps a company with no members alive if a personal representative agrees in writing within 90 days, and the agreement can make that agreement compulsory.
9. Federal tax election and the authorised signer
Record whether the company is taxed as a partnership, an S corporation on Form 2553 or a corporation on Form 8832, name who signs, and appoint the partnership representative. Section 347.081.1(8) expressly contemplates tax election provisions in the agreement. The classification rules themselves come from the IRS guidance for limited liability companies.
10. Amendment method and deadlock
Section 347.079.3(1) requires unanimity to amend a written agreement unless the agreement itself provides otherwise, so set a workable threshold. Add mediation, a buy sell trigger and a valuation method, and section 347.081.3 gives any member a route to enforce them.

Charging Orders: What Missouri Gives a Creditor, and What It Leaves Open
Section 347.119 is one paragraph long. On application by a judgment creditor of a member, a Missouri court may charge that member's interest with the unsatisfied amount of the judgment plus interest, and to the extent charged the creditor has only the rights of an assignee. Chapter 347 does not deprive a member of any exemption laws applying to the interest.
Read what is missing. Missouri does not say the charging order is the exclusive remedy, and it does not address foreclosure of the charged interest either way. Nevada writes exclusivity into NRS 86.401(2)(a) and covers single owner companies expressly; Montana, Minnesota and Nebraska all use the word exclusive and then permit foreclosure on a showing. Missouri says none of that. A Missouri member facing a personal judgment is relying on the assignee limitation in section 347.119 and on the surrounding structure, not on a statutory promise of exclusivity.
That puts more weight on drafting. Section 347.115.1 lets the agreement restrict assignment, and an assignee who has not been admitted under section 347.113 gets distributions and nothing else, with no vote and no access to management. A distribution policy tied to a stated reserve and a manager determination under section 347.101.1, rather than a fixed quarterly schedule, is the practical difference between a charging order that collects and one that waits.
Duties Under Section 347.088, and the Limits of Rewriting Them
Missouri sets a real default standard and then lets the agreement move it partway. Section 347.088.1 says that except as otherwise provided in the operating agreement, an authorised person shall discharge their duties in good faith, with the care a corporate officer of like position would exercise under similar circumstances, and in the manner a reasonable person would believe to be in the best interest of the company. Borrowing the corporate officer standard is deliberate and it is a higher bar than the gross negligence floor several neighbouring states use.
Section 347.088.2(2) allows duties and liabilities to be expanded or restricted by the agreement. Note the verbs: expanded or restricted, not eliminated. Missouri does not go as far as Nevada or New Hampshire, both of which permit elimination. Section 347.088.3 adds a trustee obligation: every member or manager must account to the company for any profit or benefit derived without the informed consent of more than one half by number of the disinterested managers or members, from any transaction connected with the business or from personal use of company property, including confidential information. Section 347.088.4 then relieves a non managing member in a manager managed company of duties owed solely by reason of being a member.
The drafting move that follows is the consent mechanism. If a member will do business with the company, write the disclosure and approval procedure so the section 347.088.3 informed consent is documented before the transaction, not argued about afterwards.
Missouri Series Under Section 347.186, and the Six Conditions
Missouri permits designated series. Section 347.186.1 lets the operating agreement establish, or provide for the establishment of, a designated series of members, managers or interests with separate rights, powers or duties as to specified property, obligations, profits and losses, and each series may have its own business purpose or investment objective.
The liability separation in section 347.186.2(1) is conditional on six things, and Missouri asks for more than most states. The agreement must create the series. Separate and distinct records must be maintained for each. The assets of each series must be accounted for separately, whether held directly or through a nominee. The agreement must contain the limitation on series liability. Notice of that limitation must be included in the company's articles of organization. And the company must have filed articles that separately identify each series intended to have limited liability.
The last two are the ones that fail in practice, because they are public filings rather than drafting. A Missouri series structure only works if the internal document and the charter record agree with each other, so a change to the series line up means an amendment of the articles, not just a redraft.
Authority, Banks and What Counterparties Ask For
Missouri does not offer a stand alone statement of authority filing. Section 347.079.1 makes the articles of organization the public statement of how management is vested and who may manage, and the operating agreement then restricts or enlarges those rights. A counterparty who wants certainty reads the articles first and asks for the agreement second.
A Missouri bank opening a business account will ask for the filed articles, the EIN letter, identification for each beneficial owner and either the operating agreement or a members resolution naming the authorised signers. Federal customer due diligence rules make the bank identify and certify beneficial owners of a legal entity customer, and the membership schedule inside the agreement is what makes the percentages verifiable. Title companies handling Missouri real estate and equipment lenders ask for the same package, as do the states where you later register a foreign entity.
Keep the signed agreement with the rest of the diligence file: the articles, the current registered agent designation, a recent certificate of good standing and any fictitious name registration.
The Consequences of Ignoring Section 347.081, Priced Out
There is no Missouri fine. The exposure is structural, and it lands in three places.
Start with ownership. Because section 347.113.1 ties membership to the operating agreement, a Missouri company with no document has no clean record of who its members are. In a dispute the answer becomes a fact question resolved by emails, deposit records and testimony. Take a company with $1.4 million of enterprise value where one participant claims a 50 per cent interest and the founder says the arrangement was employment plus a bonus. The gap between those positions is $700,000, and it is decided by whichever story a judge believes.
Then the money. On a company that has returned $300,000 of contributed capital and now earns $400,000 a year, section 347.101.2 splits that $400,000 equally among the members regardless of who funded the business. Between a member who contributed $280,000 and one who contributed $20,000, the equal split moves roughly $130,000 a year away from the funding member compared with a pro rata clause. Over five years that is $650,000 decided by a default nobody chose.
Finally the exit. A member serves the 90 day notice section 347.121.1 permits. Under section 347.137.1(3) a majority by number of the remaining members can then agree, within 90 days, to dissolve the company outright. On a business with $900,000 of annual revenue, a forced wind up instead of a negotiated buyout typically costs 30 to 50 per cent of enterprise value, before the $60,000 to $200,000 each side spends on a contested valuation and a judicial dissolution petition under section 347.143.
Five Mistakes Missouri Filers Keep Making
Mistake 1: Treating "shall adopt" as advisory
Because section 347.081 has no penalty, the requirement gets read as optional. It is not, and the cost of ignoring it shows up in section 347.113.1, where membership itself depends on the document. Adopt something, sign it, and date it.
Mistake 2: A sole owner relying on an oral understanding
Section 347.015(13) permits an oral agreement only among all members. For a sole owner the definition recognises a written declaration and nothing else. A single-member Missouri company with nothing on paper fails both section 347.015(13) and section 347.081.1 at once.
Mistake 3: Admitting a member without amending the document
Section 347.113.2 admits a member by making them a party to the operating agreement and complying with its terms, or on the written consent of all members. Paying someone a share of profit is not admission. If the schedule of members is not updated and signed, the new participant may be an assignee, an employee or nothing at all.
Mistake 4: Trying to file it with the Secretary of State
There is no channel for it and no fee. What does belong in the public record is the management structure under section 347.079.1 and, for series companies, the notice and identification required by section 347.186.2(1). Everything else stays internal.
Mistake 5: Creating series in the agreement and stopping there
Section 347.186.2(1) needs the articles to carry notice of the liability limitation and to separately identify each series, on top of the separate records and separate accounting. An agreement that names four series while the articles say nothing gives you four labels and one pool of assets.
Three Missouri Companies in Practice
Example: a barbecue restaurant group in Kansas City
Westport Smokehouse Group LLC opened with one member funding $265,000 of build out and another running the kitchen for wages. After the capital was returned, section 347.101.2 split the next $340,000 of profit equally. The agreement they adopted set a 70 to 30 split until a stated return threshold, then 55 to 45, and required unanimous consent for any new location.
Example: a logistics brokerage in Springfield
Ozarks Freight Partners LLC had three members and no written document. One served notice under section 347.121.1 and the other two, being a majority by number, moved to dissolve under section 347.137.1(3) rather than buy him out. The business was doing $2.1 million in revenue. The agreement adopted by the successor entity removed the section 347.137.1(3) trigger entirely and replaced it with a buyout at three times trailing earnings over 48 months.
Example: a four series farm equipment lessor in Columbia
Boone County Implement LLC set up four designated series in its operating agreement covering $1.9 million of equipment, but its articles of organization named none of them. A $185,000 claim against the tillage fleet reached the whole company, because section 347.186.2(1)(e) and (f) require the articles to carry the notice and identify each series. The fix was an amendment to the articles, four separate ledgers and four bank accounts.
How File.Business Drafts Missouri Operating Agreements
We draft to the sections that decide Missouri outcomes: the membership schedule section 347.113 depends on, a distribution clause that displaces the return then equal split in section 347.101.2, withdrawal and dissolution terms that neutralise sections 347.121.1 and 347.137.1(3), a documented consent procedure for the section 347.088.3 trustee obligation, and where series are used, drafting that matches the articles. For a sole owner we produce the written declaration section 347.015(13) requires. Included with Missouri LLC formation or available on its own.
Free templates against drafted agreements
A generic template rarely mentions chapter 347 at all, which means it displaces none of the specific Missouri defaults described above and does not satisfy the sole member writing point. For a dormant single owner company it may be enough; for anything with two members, outside capital, real property or series, it is not. At $99 the drafted version costs less than an hour of Missouri counsel. Read operating agreement essentials and LLC against S corporation next, and Missouri annual filings for the ongoing calendar.
Missouri operating agreement questions
Does Missouri require an LLC to have an operating agreement?
Yes. Section 347.081.1 of the Revised Statutes of Missouri says the member or members of a limited liability company shall adopt an operating agreement containing such provisions as they may deem appropriate. Missouri is one of only a handful of states whose statute uses a mandatory verb. There is no penalty for ignoring it, but section 347.113.1 defines membership by reference to the agreement, so a company without one has no clean record of who its owners are.
Does a Missouri operating agreement have to be in writing?
It depends on how many members there are. Section 347.015(13) defines an operating agreement as any valid agreement, written or oral, among all members, or a written declaration by the sole member. A multi-member Missouri company may therefore have an oral agreement, but a single owner company must have a written declaration for the document to exist at all.
Do I file my operating agreement with the Missouri Secretary of State?
No. The Business Services Division records the articles of organization and later charter documents. The operating agreement is not among them, there is no form for it, and there is no fee, because there is no filing. Keep the signed original with the company records.
What does it cost to put a Missouri operating agreement in place?
The State charges nothing, because the document is never submitted. The only cost is drafting. File.Business prepares a Missouri specific agreement at $99 flat, including the written declaration a sole member needs under section 347.015(13).
How are profits split in a Missouri LLC with no operating agreement?
Section 347.101.2 sets the order. Distributions are shared first in proportion to the cash and other contributions each member made, until every member has been returned their contribution. After that, distributions are shared by the members equally, regardless of who funded the business. That second step is the default most founders would not have chosen.
Can a creditor of a Missouri member take over the membership interest?
Section 347.119 lets a court charge the member's interest with the unsatisfied amount of a judgment, and to the extent charged the creditor has only the rights of an assignee. Missouri does not say the charging order is the exclusive remedy and does not address foreclosure either way, so the practical protection comes from the assignment restrictions and distribution policy written into the agreement.
What happens if a member of a Missouri LLC quits?
Section 347.121.1 lets a member withdraw at the times specified in writing in the agreement, or at any time on 90 days prior written notice. Section 347.121.3 leaves the departed member with only the rights of an assignee. The bigger risk is section 347.137.1(3), which allows a majority by number of the remaining members to dissolve the company within 90 days of the withdrawal unless the agreement says otherwise.
