Buy-Sell Agreements: The Document That Decides Whether Your Business Survives Its Owners
Every co-owned business will eventually lose an owner — to retirement, death, disability, divorce, or a falling-out. Oregon law has default answers for what happens next, and they are almost never the answers you would choose. A buy-sell agreement is how you choose your own.
Every business with more than one owner has an expiration date on its current ownership. Someone will retire. Someone will die. Someone will get divorced, go bankrupt, become disabled, or simply want out. None of that is pessimism — it's arithmetic. The only question is whether the terms of that transition were decided in advance by the owners, or after the fact by a statute nobody read and a negotiation nobody wanted.
A buy-sell agreement is how owners decide in advance. It's a contract — sometimes a standalone document, more often a set of provisions inside an LLC operating agreement — that answers the ownership questions before they're asked: what events trigger a buyout, who can buy, at what price, on what timeline, and with what money.
What happens to Oregon businesses that skip this is documented elsewhere on this blog, in detail. The short version: the default rules take over, and the default rules are a mess.
What Oregon's Default Rules Actually Do
The strongest case for a buy-sell agreement isn't hypothetical. It's what Oregon law does to co-owned businesses that don't have one.
If you never formed an entity, you're in a general partnership governed by ORS Chapter 67, and the defaults are harsh. As covered in the informal partnership post, a two-person partnership with no agreement can't do a clean buyout at all when one partner leaves — the statutory text points toward dissolving and winding up the entire business. Larger partnerships get a mandatory buyout on statutory terms, with fair value fixed as of the departure date, deadlines measured in 120-day windows, and litigation as the tiebreaker.
If you formed an LLC, ORS Chapter 63 has its own defaults, and they produce a different kind of problem. As covered in the LLC owner dies post, when a member dies, their heirs inherit the economic interest — the right to distributions — but not the right to vote or manage. The surviving owner ends up running the business alone while sending checks to a co-owner's family who have no formal role and no exit. Nobody chose that arrangement. It's just what the statute does when the operating agreement is silent.
If an owner divorces, an ownership interest is property, and property gets divided. Without transfer restrictions in a buy-sell provision, a court can award part of the business to an owner's ex-spouse — and the other owners have no mechanism to prevent it or unwind it. You can end up in business with someone none of you ever chose.
These aren't edge cases. They're the standard outcomes for businesses running on default rules. A buy-sell agreement exists to replace every one of them with terms the owners actually picked.
The Three Questions Every Buy-Sell Agreement Must Answer
Strip away the drafting and a buy-sell agreement is three decisions.
1. What triggers it?
The triggering events define when the agreement activates. A complete agreement covers:
Death — the estate or heirs are bought out rather than becoming co-owners
Disability — with a real definition and a waiting period, so a temporary illness doesn't trigger a buyout but a permanent incapacity doesn't leave the business in limbo
Voluntary exit — retirement or simply wanting out, usually with notice requirements
Divorce — a right to buy back any interest awarded to a former spouse
Bankruptcy or creditor problems — so an owner's personal financial collapse doesn't put a trustee or creditor in your ownership group
Expulsion — the grounds and process for removing an owner for cause
Deadlock — a resolution mechanism for 50/50 owners who can no longer agree, which is its own quiet business-killer
Miss a trigger and you've left that scenario to the defaults described above.
2. What's the price?
Valuation is where buy-sell agreements most often fail in practice, because the owners picked a method without understanding its consequences. The common approaches:
An agreed value, updated periodically. Simple and predictable — until nobody updates it for six years and the certificate says the business is worth a third of what it is. Stale agreed values generate more disputes than they prevent.
A formula — a multiple of earnings or revenue. Objective and cheap to apply, but formulas that made sense at signing can wildly misprice a business whose margins or model have changed.
Appraisal at the time of the trigger. The most accurate and the most expensive, and the agreement needs to say who picks the appraiser and what standard of value applies.
There's no universally right answer — but there's usually a right answer for a specific business, and it depends on the size of the company, how volatile its value is, and how much the owners trust each other. Whatever the method, the agreement should say explicitly whether discounts for minority interests or lack of marketability apply. Silence on that question is an invitation to litigate it.
3. Where does the money come from?
A buyout obligation the business can't fund is a lawsuit with extra steps. The funding mechanism is the part most template agreements wave at and most disputes turn on:
Life insurance is the classic answer for death buyouts — the policy pays exactly when the obligation arises. The structural choice is whether the owners hold policies on each other (cross-purchase) or the company holds them (redemption), and that choice has real tax consequences. In 2024, the U.S. Supreme Court held unanimously in Connelly v. United States that life insurance proceeds a company receives to fund a redemption count toward the company's value for federal estate tax purposes — with no offset for the buyout obligation. The same valuation logic matters for Oregon owners, where the state estate tax threshold is just $1 million and an inflated business value can be the thing that crosses it. After Connelly, the structure of buyout insurance is not a detail — it belongs in the same conversation as the agreement itself.
Installment payments spread a buyout the business can't write a check for — with interest, security, and default terms spelled out.
Disability buyout insurance exists for the disability trigger and is chronically overlooked.
An agreement that names a fair price but no workable funding source hasn't solved the problem. It has scheduled it.
Where the Buy-Sell Lives — and What It Has to Coordinate With
For most Oregon LLCs, buy-sell provisions belong inside the operating agreement rather than in a separate contract — one document, one set of defined terms, no risk of the two contradicting each other. As covered in the [operating agreement post], template operating agreements routinely omit these provisions entirely or fill them with generic language that collapses under a real dispute.
The less obvious point is that a buy-sell agreement has to work with each owner's estate plan. The agreement controls what happens to the interest at death; the estate plan controls where the sale proceeds go and who acts for the estate. When the two are drafted without reference to each other — an operating agreement that requires a buyout, an estate plan that assumes the business passes to a spouse — the result is confusion at the worst possible moment. For business owners, this is the single strongest argument for having the same firm, or at least coordinated counsel, on both sides of that line.
If You Already Have One
An old buy-sell agreement can be worse than none, because everyone assumes the problem is handled. Three questions worth asking about yours:
When was the value last updated? If your agreement uses an agreed value and no one has touched it in years, it no longer reflects your business — and the gap between the certificate and reality is exactly the number someone will sue over.
Does the funding still work? Policies lapse, coverage amounts that fit a $400,000 business don't fit a $2 million one, and Connelly changed the calculus on company-owned policies. Insurance-funded agreements need periodic review against both the business's value and current law.
Does it match your current ownership? Agreements drafted for two founders don't automatically accommodate the third member admitted in 2022 or the interest that moved into someone's trust. If the signature pages don't match the cap table, the agreement may not bind the people who matter.
Bottom Line
Every co-owned Oregon business ends its current ownership eventually. The defaults that govern an undocumented transition are documented on this blog in painful detail — dissolution traps for partnerships, voteless heirs for LLCs, ex-spouses with equity for everyone. A buy-sell agreement replaces all of it with terms you chose: defined triggers, a valuation method that fits your business, and funding that actually exists.
The right time to draft one is when everyone still likes each other and nobody needs it. The most expensive time is the only other option.
