Your partner just told you they want out, and your mind is already racing: Do we have to shut the whole thing down? Who gets what? Can I keep running it without them? Take a breath — in most Missouri cases, one partner leaving does not have to mean the business dies. You usually have two paths: one of you buys out the other and the company keeps going, or you fully dissolve and wind up, pay the debts, and split what's left. Which path is even available depends almost entirely on one thing most people skip past.
That one thing is your entity type and your governing document. A general partnership, an LLC, and a corporation each follow a different Missouri rulebook, and a written agreement you may have signed years ago usually controls how a buyout is priced and triggered. So before you negotiate a number or call it quits, get those two facts straight — they decide everything that follows.
First, figure out what kind of business you actually have
This is the question that changes the whole analysis, because the default rules differ by entity:
- General partnership — governed by the Missouri partnership act (RSMo Chapter 358). A partner can dissociate (formally leave), which can trigger either a buyout of their interest or a winding up of the partnership, depending on the agreement and the circumstances.
- LLC — governed by the Missouri Limited Liability Company Act (RSMo Chapter 347) and, above all, your operating agreement. The Act lets members design their own exit, valuation, and management terms, so your rights depend first on that document and only secondarily on the statute's defaults.
- Corporation — governed by the General and Business Corporation Law (RSMo Chapter 351). A shareholder exits by selling or redeeming shares, and a full shutdown means a formal dissolution under the statute.
Don't guess. Pull your Secretary of State filing and your formation documents to confirm exactly which one you are. The rest of this guide assumes you've nailed this down.
Find and read your governing agreement
Whatever your entity, the governing document usually controls — and reading it carefully is the single most valuable hour you'll spend.
- Look for a buy-sell agreement — sometimes a standalone document, sometimes a section inside your operating or partnership agreement. It typically spells out the triggering events (a partner wanting out is a classic one), the valuation method, and the payment terms.
- Note the valuation method. Agreements commonly fix value by book value, fair market value, or a required independent appraisal. This single clause can be the difference between a fair number and a fight.
- Check transfer restrictions and rights of first refusal. Many agreements give you or the company the first right to buy the departing partner's stake before they can sell to an outsider.
If you have a clear agreement, you may already have your answer — follow it. If there's no agreement, the statute's default rules apply: Chapter 358 supplies dissociation, winding-up, and distribution rules for partnerships; Chapter 347 supplies defaults for LLCs where the operating agreement is silent.
Decide between a buyout and a full dissolution
There are really two destinations, and it helps to name them early.
- Path A — One partner buys the other out. The company survives; only the ownership changes. The whole game here is valuation: agree on what the business is worth and what the departing partner's share of that is. If your agreement fixes the method, use it. If not, expect a negotiation — and often a professional appraisal — over book value versus fair market value.
- Path B — Full dissolution and winding up. You shut it down. In Missouri the order matters: you wind up the business, pay creditors first, and only then distribute what's left to the owners according to the agreement or statute. For an LLC or corporation, this also means filing the proper dissolution documents with the state.
A buyout is usually the gentler, value-preserving option — nobody has to liquidate a working business at fire-sale prices. Reserve full dissolution for when neither of you wants to continue, or when you simply can't agree.
Get a real valuation before you negotiate
Whether you're buying out or winding up, a number pulled from thin air helps no one. Put the argument on professional footing.
- Hire a business appraiser if your agreement doesn't fix the value or you both distrust the figure. A defensible valuation takes the emotion out of the negotiation.
- Understand the standards. Book value (assets minus liabilities on the books) is simple but often undercounts a healthy business. Fair market value tries to capture what a willing buyer would pay. The two can differ dramatically.
- Account for debts, guarantees, and taxes. If your departing partner personally guaranteed a loan, a clean exit has to release that guarantee. And how you structure the buyout can carry real tax consequences — loop in your accountant early.
Paper the deal and file the right documents
Handshake deals between partners who are parting ways do not hold up. Reduce everything to writing.
- Sign a buyout or wind-up agreement with a mutual release. Spell out the price, the payment schedule, who takes which assets and debts, and a release so neither of you can come back later with claims. This is the document that lets you both move on.
- File with the Missouri Secretary of State. For an LLC, file the appropriate articles of termination or dissolution (or a withdrawal/amendment if only a member is leaving); for a corporation, file articles of dissolution under Chapter 351. A general partnership can file a statement reflecting the change as well.
- Give notice to creditors and handle the taxes. Winding up means notifying known creditors, settling debts, closing tax accounts, filing final returns, and canceling licenses and registrations. Skipping this can leave you personally exposed.
When you're deadlocked: judicial dissolution as a fallback
Sometimes neither side will move — they won't accept your buyout price, and they won't agree to wind up. When owners are genuinely deadlocked, Missouri courts can step in.
- A court can order a judicial dissolution, winding up and liquidating the business, when owners are hopelessly deadlocked, when those in control act oppressively, or when assets are being wasted (for corporations, this runs through RSMo § 351.494, with analogous relief for LLCs and partnerships).
- Because forced liquidation usually destroys value everyone built, courts often prefer — and may order — a fair-value buyout instead.
Think of judicial dissolution as the backstop, not the plan. The credible threat of it frequently pushes a stubborn partner toward the negotiated buyout you wanted all along.
Frequently Asked Questions
My partner wants out — do we have to dissolve the whole business?
No, not usually. One partner leaving can be handled by a buyout, where you (or the company) purchase their interest and the business keeps running. Full dissolution and winding up is only one of two paths, and it's typically reserved for when neither owner wants to continue or you can't agree on terms.
Which Missouri law governs my partner's exit?
It depends on your entity. A general partnership follows RSMo Chapter 358, an LLC follows RSMo Chapter 347 and its operating agreement, and a corporation follows RSMo Chapter 351. Identifying your entity type is the first thing to do, because the default rules and exit mechanics differ for each.
How do we figure out what my partner's share is worth?
Start with your governing agreement — many fix a valuation method like book value, fair market value, or an independent appraisal. If there's no agreement or you distrust the number, hire a business appraiser. Book value is simple but often undercounts a healthy company, while fair market value aims at what a buyer would actually pay.
What if we don't have a written agreement?
Then the statute's default rules fill the gap. For a partnership, Chapter 358 supplies the rules for dissociation, winding up, and distribution; for an LLC, Chapter 347 supplies defaults where the operating agreement is silent. The defaults are rarely as tailored as a well-drafted agreement, which is exactly why papering future deals in writing matters.
What happens to our debts when we dissolve?
In a winding up, the order is fixed: you pay creditors first, then distribute whatever remains to the owners. You should also give notice to known creditors and settle the company's obligations before splitting assets. If a partner personally guaranteed a loan, the exit agreement needs to release that guarantee, or they stay on the hook.
What if my partner refuses every reasonable offer?
If you're truly deadlocked, a Missouri court can order a judicial dissolution under provisions like RSMo § 351.494, winding the business up. Because liquidation usually destroys value, courts often prefer to order a fair-value buyout instead — and the realistic prospect of that outcome often brings a stubborn partner back to the negotiating table.
