Buy-Sell Agreements — What Every Business Owner Should Know

A buy-sell agreement is a contract between co-owners that answers a question no one wants to think about: what happens to your share of the business if you die, become disabled, retire, divorce, or decide to leave? It defines who can buy, at what price, and how the purchase gets funded. Without one, every triggering event becomes a crisis.

The Agreement Nobody Wants to Think About

Every closely held business with more than one owner needs a buy-sell agreement. And yet we regularly meet owners who either don't have one, haven't looked at theirs in a decade, or signed one years ago and have no idea what it says.

That's a problem. A buy-sell agreement protects your business when something unexpected happens. Death. Disability. A partner who wants out. A divorce that drags the company into court. Without a clear agreement, these events don't just affect the people involved. They threaten the business itself.

Two decades of advising closely held businesses through ownership transitions has taught us something consistent. Buy-sell agreements come up in almost every engagement. Owners who plan ahead have options. Owners who don't get stuck reacting to crises they could have prevented.

What Does a Buy-Sell Agreement Do?

A buy-sell agreement is a legally binding contract between co-owners. It spells out what happens to an owner's shares when a triggering event occurs. Think of it as a prenuptial agreement for your business partnership. Nobody wants to imagine the worst case, but the worst case doesn't care whether you planned for it.

The agreement answers three questions.

• Who can buy the departing owner's shares? The remaining owners, the company itself, or both.
• What price will be paid? Based on a predetermined formula, an independent appraisal, or a combination.
• How will the purchase be funded? Insurance, installment payments, company reserves, or some other mechanism.

Without these answers locked in, every ownership change becomes a negotiation. Negotiations that happen during a crisis, while someone is grieving or angry or desperate, rarely produce fair outcomes.

Six Trigger Events That Force the Conversation

A good buy-sell agreement covers the events most likely to disrupt ownership. These aren't hypothetical. We've seen every one of them force difficult conversations between unprepared partners.

Death. The most common trigger. If an owner dies, the agreement determines whether the estate sells back to the business or remaining owners, at what price, and on what terms. Without one, you could end up in business with a deceased partner's heirs.

Disability. Long-term disability can leave an owner unable to contribute while still holding equity. The agreement defines what qualifies as a triggering disability and how the buyout works.

Retirement. Partners don't always retire on the same timeline. The agreement protects the retiring owner's right to fair value and protects remaining owners from being forced to pay all at once.

Voluntary departure. An owner decides to leave. Maybe they want to start something new. Maybe there's a disagreement about direction. The agreement prevents someone from walking away with their shares and competing with the business.

Divorce. In many states, a business interest is marital property. Without a buy-sell agreement, a divorce could transfer ownership to an ex-spouse. A well-drafted agreement prevents this.

Bankruptcy. If an owner faces personal bankruptcy, creditors may target their ownership interest. The agreement gives remaining owners the right to purchase those shares before creditors claim them.

Which Structure Fits Your Business?

Buy-sell agreements fall into three structures, each with trade-offs depending on the number of owners, tax considerations, and business organization.

Cross-purchase agreement. Each owner agrees to buy the others' shares when a trigger event happens. This works well with two or three owners. It gets complicated fast with more. A four-owner business would need twelve separate insurance policies to fund all possible purchase scenarios.

Entity redemption (stock redemption) agreement. The company buys back the departing owner's shares. Simpler when there are multiple owners because the business is the buyer in every case. But the tax treatment can be less favorable, and using company funds means less cash for operations.

Hybrid agreement. A combination of both. The company gets the first right to purchase, and if it declines, remaining owners can buy individually. This gives everyone the most flexibility, and it's the structure we see most often in well-advised closely held businesses.

Your attorney and tax advisor should weigh in on which structure fits. The answer depends on how many owners you have, how the entity is organized, and the tax implications for each party.

Getting the Valuation Right

The price question is where buy-sell agreements either protect people or create conflict. Getting valuation right matters more than almost anything else in the agreement.

Fixed price. The owners agree on a dollar amount and update it periodically. In practice, people forget to update it, and a number set five years ago has no connection to what the business is worth today.

Formula-based. The agreement includes a formula, often a multiple of earnings, revenue, or book value. This updates as the business performs. The risk is that a single formula can't account for unusual years, market shifts, or changes in the business mix.

Independent appraisal. A third-party appraiser determines fair market value when a trigger event occurs. This produces the most defensible number, but it takes time and costs money. If the agreement doesn't specify who selects the appraiser, even this approach can lead to disputes.

Combination. Many agreements use a formula as the default with a provision for an independent appraisal if either party disagrees.

How Will You Pay for the Buyout?

An agreement is only as good as the money behind it. We've seen buy-sell agreements that spelled out every detail and were completely unfunded. When a trigger event happened, nobody could pay.

Life insurance. The most common funding mechanism for death triggers. Each owner takes out a policy on the others (cross-purchase) or the company insures all owners (entity redemption). When an owner dies, proceeds fund the purchase. It works well, as long as coverage keeps pace with business value.

Disability insurance. Same concept, different trigger. Disability buyout policies are less common and more expensive, but worth exploring if owner disability would strain the business.

Installment payments. The buyer pays the selling owner (or their estate) over time, with interest. Common for retirement and voluntary departure triggers. The risk is that payments depend on the business continuing to perform.

Sinking fund. The company sets aside money over time to fund a future buyout. This requires discipline. It works best as a supplement to insurance rather than a primary mechanism.

Most well-structured agreements use a combination. Insurance for death and disability. Installment terms for retirement and departure. A sinking fund as backstop.

Five Mistakes That Make Agreements Worthless

We've reviewed dozens of buy-sell agreements for clients. The same problems show up again and again.

The agreement is outdated. The business was worth $2 million when the agreement was signed. It's worth $12 million now. The fixed price hasn't been updated. One partner dies, and the surviving partner buys a $12 million business for $2 million. The estate sues. Everyone loses.

The valuation is unrealistic. Sometimes owners set a number too high, hoping it protects them. Sometimes too low, for tax reasons. Either way, when the trigger event happens, one side feels cheated.

The triggers aren't funded. The agreement says the company will buy back shares on death, but there's no insurance policy. The company doesn't have the cash. The buyout doesn't happen, or it bankrupts the business.

The agreement doesn't match current ownership. Partners have been added or removed. Ownership percentages have changed. The agreement still references the original two founders. As written, it's unenforceable.

No one has read it recently. This is the most common problem we see. The agreement sits in a filing cabinet. No one reviews it. Circumstances change, and the document doesn't.

Does Your Buy-Sell Agreement Connect to Your Succession Plan?

A buy-sell agreement isn't a succession plan. But it's a piece of one.

Succession planning answers the bigger question: who takes over, when, and how? A buy-sell agreement handles one specific piece: what happens to ownership when certain events force the question.

Here's where they connect. If your succession plan involves selling to your management team over time, the buy-sell agreement should reflect that path. If it doesn't, you could have a plan that says one thing and a legal document that says another. We've seen that conflict. It's expensive to unwind.

Build your buy-sell agreement as part of a larger succession conversation, not as a standalone legal exercise. Our exit planning resource kit covers how these pieces fit together. Your attorney drafts it, but the strategy should come from a broader view of where the business is headed.

Is Your Agreement Protecting You or Collecting Dust?

If you don't have a buy-sell agreement, get one. If you have one you haven't reviewed in the last few years, pull it out and read it. Ask yourself these four questions.

• Does it cover all the trigger events that could affect your ownership?
• Is the valuation method producing a number that reflects what the business is worth today?
• Is every trigger event funded, not just on paper, but with actual policies or reserves?
• Does the agreement match the current ownership structure?

This is strategic guidance, not legal advice. The actual agreement needs to be drafted by a qualified attorney. But the thinking behind it, what triggers to cover, how to value the business, how to fund the buyout, how it fits your larger plan, is where we spend our time with clients.

We've guided closely held businesses through $3 billion in ownership transitions. When you're ready to look at whether your buy-sell agreement is working for you, that's a conversation worth having.
