Every closely held business with more than one owner will eventually face a transition event. An owner will die, become disabled, retire, get divorced, or simply decide to leave. The question is not whether one of these events will happen—it is whether the business has a plan for when it does.
A buy-sell agreement is that plan. It is a legally binding contract among business owners (and sometimes the entity itself) that dictates what happens to an ownership interest when a triggering event occurs. It establishes who can buy, who must sell, at what price, and on what terms. Without one, you are leaving the most consequential decisions about your business—who owns it, how much it is worth, and who gets to decide—to default state law, courtroom litigation, or the whims of an owner’s heirs, ex-spouse, or creditors.
Most closely held businesses either have no buy-sell agreement at all, or they have one that was drafted years ago and never updated. Both situations produce the same result: a crisis that is exponentially more expensive and destructive than the agreement would have been. This page covers everything business owners need to know about buy-sell agreements—what they are, how they work, and why getting this document right is worth more than almost any other legal investment you will make.
What Is a Buy-Sell Agreement?
A buy-sell agreement is a contract that governs the mandatory purchase and sale of a business owner’s interest upon certain triggering events. Think of it as a prenuptial agreement for business partners—it establishes the rules for separation before emotions, money, and lawyers make rational negotiation impossible.
Who needs one? Any business with two or more owners. This includes partnerships, multi-member LLCs, and corporations with more than one shareholder. It does not matter whether the owners are family members, lifelong friends, or arms-length investors. The need is universal because the underlying risk is universal: ownership transitions are inevitable, and unplanned transitions destroy businesses.
The agreement typically addresses several core questions:
- Transfer restrictions: Can an owner sell or transfer their interest to anyone they choose, or must they first offer it to the other owners or the entity?
- Mandatory buyouts: Upon which events must an owner (or their estate) sell their interest?
- Pricing: How is the purchase price determined?
- Payment terms: How and when is the purchase price paid?
- Funding: What mechanisms are in place to ensure the buyer can actually pay?
Without a buy-sell agreement, you are relying on default state law—and default state law rarely produces the outcome anyone wants. In Minnesota, if a member of an LLC dies without a buy-sell agreement, the deceased member’s interest passes to their estate. The remaining members may find themselves in business with a spouse, adult child, or trustee who has no interest in the business. The surviving owners have no automatic right to purchase the interest. The result is deadlock, litigation, or both.
A well-drafted buy-sell agreement eliminates this uncertainty entirely. When a triggering event occurs, the agreement dictates exactly what happens—removing the need for negotiation at the worst possible time.
When Buy-Sell Agreements Trigger
The value of a buy-sell agreement depends entirely on whether it covers the events that actually occur. The most common triggering events—and the ones your agreement must address—are the following.
Death of an Owner
When an owner dies, their ownership interest becomes part of their estate. Without a buy-sell agreement, the surviving owners may find themselves in business with the deceased owner’s heirs—people who may have no knowledge of the business and no alignment with the surviving owners’ goals. A buy-sell agreement requires the estate to sell and gives the remaining owners (or the entity) the right and obligation to buy.
Permanent Disability
Disability is statistically more likely than death during working years, yet many buy-sell agreements either omit it or define it poorly. If an owner becomes permanently disabled, the business loses their contribution but the disabled owner retains their ownership interest—and their right to distributions. The agreement must define disability precisely and establish the timeline for the buyout.
Retirement or Voluntary Departure
An owner who wants to leave the business needs a mechanism to sell their interest at a fair price. Without one, the departing owner is trapped—there is no public market for a minority interest in a closely held company. The agreement establishes the right to sell upon retirement and the terms under which the buyout occurs.
Divorce
Divorce is the most commonly omitted trigger event—and one of the most dangerous. In a divorce proceeding, a court may award part of the business interest to the non-owner spouse. Without a buy-sell agreement that addresses divorce, the remaining owners may find themselves in business with their partner’s ex-spouse. A well-drafted agreement requires the divorcing owner to buy out any interest awarded to the non-owner spouse, keeping ownership where it belongs.
Involuntary Transfer
If an owner files for bankruptcy or has a judgment creditor seize their business interest, the remaining owners face the same problem as divorce: an unwanted new owner. The agreement should require the indebted owner to sell their interest upon any involuntary transfer, giving the remaining owners the right to purchase before the interest passes to a third party.
Disputes and Deadlock
In a 50/50 owned business, disagreements between owners can paralyze operations. A buy-sell agreement can include a deadlock provision—sometimes called a “shotgun” or “Texas shootout” clause—that provides a mechanism for one owner to buy out the other when the owners cannot agree on a fundamental business decision. Without this mechanism, the only resolution is litigation or dissolution.
Termination of Employment
For businesses where owners are also employees, termination of employment (whether voluntary or involuntary) should trigger the buy-sell provisions. An owner who no longer works for the company but retains their ownership interest can create significant tension—they continue to share in profits without contributing to operations. The agreement should address whether termination triggers a mandatory buyout or a right of first refusal.
Three Types of Buy-Sell Agreements
Buy-sell agreements come in three basic structures. The right choice depends on the number of owners, the tax situation, the funding mechanism, and the flexibility the owners need. For a detailed comparison of the tax and structural implications, see our article on cross-purchase vs. entity redemption buy-sell agreements.
| Cross-Purchase | Entity Redemption | Hybrid (Wait-and-See) | |
|---|---|---|---|
| Who buys | Remaining owners personally | The business entity | Either—decided at the time of the triggering event |
| Tax basis step-up | Yes—buyers receive a stepped-up basis in the purchased interest | No—entity redemption does not increase remaining owners’ basis | Depends on which option is exercised |
| Life insurance | Each owner insures each other owner | Entity purchases a policy on each owner | Flexible—policies can be held by either owners or entity |
| Number of policies needed | n × (n − 1) policies | n policies (one per owner) | Varies |
| Complexity with many owners | High—grows exponentially | Low—scales linearly | Moderate |
| Best for | 2–3 owners | Many owners; C corporations | Owners who want flexibility |
Cross-Purchase Agreements
In a cross-purchase arrangement, the remaining owners personally buy the departing owner’s interest. Each owner agrees to purchase their proportionate share. The primary advantage is tax: the purchasing owners receive a cost basis in the acquired interest equal to what they paid. When they eventually sell, their taxable gain is reduced by that basis.
The primary disadvantage is complexity. With two owners, you need two insurance policies. With three owners, you need six. With five owners, you need twenty. Each owner must maintain policies on every other owner, and the policies must be kept current as ownership percentages and valuations change. For businesses with more than three owners, the administrative burden becomes significant.
Entity Redemption Agreements
In an entity redemption (also called a stock redemption for corporations), the business itself purchases the departing owner’s interest. The entity maintains a single life insurance policy on each owner, dramatically simplifying the insurance logistics. This structure works well for businesses with many owners or where owners have disparate financial resources—since the entity, not the individual owners, funds the purchase.
The tax disadvantage is real: an entity redemption does not give the remaining owners a stepped-up basis in their interests. When they eventually sell, their original basis remains unchanged, potentially resulting in a larger taxable gain. For C corporations, additional complications arise under the constructive dividend and attribution rules. These tax implications make professional guidance essential.
Hybrid (Wait-and-See) Agreements
A hybrid agreement defers the decision about who buys until the triggering event occurs. Typically, the entity has the first option to redeem the interest. If it declines (or can only purchase part of the interest), the remaining owners have the right to purchase on a cross-purchase basis. This structure provides maximum flexibility—the owners can choose the most advantageous structure based on the circumstances at the time of the event, including the tax environment, the entity’s cash position, and the owners’ personal situations.
The trade-off is complexity in drafting and the need to fund both possible structures. Despite this, the hybrid approach has become the most popular structure for new buy-sell agreements precisely because of its flexibility.
Pricing Mechanisms—How to Determine the Buyout Price
The pricing mechanism is the most litigated provision in buy-sell agreements. More disputes arise over the price term than over any other clause—because when a triggering event occurs, the seller wants the highest possible price and the buyer wants the lowest. If the agreement’s pricing mechanism is ambiguous, outdated, or poorly drafted, the result is litigation. To understand the valuation methods in depth, see our guide to determining what your business is worth.
Fixed Price
The simplest approach: the owners agree on a specific dollar value for the business (or for each ownership interest) and attach it to the agreement as an exhibit. The advantage is clarity—there is no ambiguity about the price. The danger is staleness. Fixed-price provisions are almost never updated. An agreement signed when the business was worth $2 million may still contain that figure ten years later, when the business is worth $8 million. The departing owner or their estate receives a fraction of the true value, or worse, the surviving owners refuse to honor an absurdly low price, and the matter ends up in court.
Formula-Based Pricing
A formula ties the buyout price to a financial metric—typically a multiple of earnings (EBITDA), revenue, or book value. The advantage is that the price adjusts automatically as the business grows. The risk is that a single formula cannot capture the nuance of business valuation. A multiple of EBITDA that is reasonable for a growing, profitable company may be wildly inappropriate for a company in decline. Formula-based pricing works best when combined with a periodic review provision that allows the owners to adjust the formula.
Appraisal at Time of Trigger
The most accurate but most expensive and time-consuming approach. When a triggering event occurs, a professional appraiser determines the fair market value of the business and the departing owner’s interest. The agreement should specify the appraiser’s qualifications, the valuation standard (fair market value is typical), and the timeline for completion.
The two-appraiser process adds a layer of protection: each side selects an appraiser, and if the two appraisals differ by more than a specified percentage, a third appraiser is engaged. The final value is typically the average of the two closest appraisals or the third appraiser’s determination. This process is more expensive but significantly reduces the risk of a biased valuation.
Many well-drafted agreements combine approaches: a formula or annual agreed-upon value serves as the default, with an appraisal process as a fallback if either party disputes the formula result.
Funding the Buy-Sell Agreement
A buy-sell agreement is only as good as the money behind it. An agreement that requires remaining owners to purchase a $3 million interest but provides no mechanism for funding that purchase is a lawsuit waiting to happen. The funding mechanism should match the triggering event.
Life Insurance
Life insurance is the most common funding mechanism for death triggers—and for good reason. It provides an immediate lump sum at precisely the moment the purchase obligation arises. The proceeds are generally income tax-free, and the cost of insurance is predictable. Whether the policies are held by the individual owners (cross-purchase) or the entity (redemption), the key is ensuring that the death benefit matches the current buyout price. Insurance purchased five years ago for $1 million of coverage is inadequate if the business is now worth $3 million.
Disability Insurance
Disability buy-sell insurance is a specialized product designed to fund a buyout when an owner becomes permanently disabled. These policies typically have a waiting period (often 12–24 months) before benefits are paid, recognizing that disability must be established as permanent before a buyout is triggered. The agreement’s disability definition and the insurance policy’s definition should match precisely—a mismatch can leave the agreement unfunded at the worst possible time.
Installment Payments
For voluntary departures—retirement, resignation, employment termination—insurance is typically unavailable or impractical. The most common alternative is a promissory note: the buyer (whether the entity or the remaining owners) pays the buyout price over time in installments, with interest. The agreement should specify the payment term, interest rate, security for the obligation, and default provisions. From the seller’s perspective, the risk is buyer default. From the buyer’s perspective, the risk is cash flow strain. The agreement must balance both.
Sinking Funds and Company Cash Flow
Some businesses establish a sinking fund—a reserve account dedicated to funding future buy-sell obligations. This provides a partial funding mechanism that reduces the size of any future installment obligation. For profitable businesses with strong cash flow, self-funding through operations is viable, but it depends on the business being healthy at the time of the triggering event—which is not always the case.
When There Is No Funding
The worst scenario: the agreement triggers, the obligation to purchase exists, and there is no money to fund it. The departing owner or their estate is owed a buyout price that nobody can pay. The result is litigation, forced sale of business assets, or the agreement being treated as unenforceable. This is why funding is not optional—it is an essential component of any buy-sell agreement that the owners expect to actually work.
Common Mistakes in Buy-Sell Agreements
After reviewing hundreds of buy-sell agreements over the years, certain mistakes appear consistently. Each one creates a gap that only becomes visible when the agreement is needed most.
Outdated or stale pricing. This is the most common problem by a wide margin. The owners agreed on a price when the agreement was signed—often years or even decades ago—and never updated it. When a triggering event occurs, the stated price bears no relationship to the actual value of the business. The selling party challenges the price, the buying party insists on the contractual terms, and the matter ends up in court.
Insufficient funding. The agreement specifies a buyout price, but the insurance policies lapsed, the sinking fund was raided for operations, or the installment terms assume cash flow that no longer exists. An unfunded buy-sell agreement is a promise without substance.
Missing trigger events. Divorce is the most commonly omitted trigger—often because the conversation is uncomfortable. Involuntary transfers (bankruptcy, creditor seizure) are the second most commonly omitted. Every omitted trigger is a scenario where the agreement provides no protection.
Conflicting provisions with the operating agreement. The buy-sell agreement says one thing about transfer restrictions; the LLC operating agreement says another. When these documents conflict, the result is ambiguity—and ambiguity in a high-stakes dispute means litigation. The buy-sell agreement and the governing entity documents must be consistent, and ideally, the buy-sell provisions should be incorporated directly into the operating agreement or bylaws.
Failure to address minority vs. majority interests. A 20% owner and an 80% owner have fundamentally different positions. Should minority interests be purchased at a discount? Should majority owners have drag-along rights? The agreement must address the economic reality that not all ownership percentages carry equal value or control.
No mechanism for deadlock. In a 50/50 business, disagreement between the two owners can paralyze operations indefinitely. Without a deadlock-breaking mechanism—whether a shotgun clause, mandatory mediation, or dissolution trigger—the only escape is litigation.
Buy-Sell Agreements for Different Business Contexts
While the core principles apply universally, certain business situations raise unique considerations that the buy-sell agreement must address.
Family Businesses
Family businesses face a distinct set of risks. Divorce of an owner-child can introduce an ex-spouse into the family enterprise. Sibling disputes can escalate beyond business disagreements into family fractures that no courtroom can repair. And the emotional weight of the founder’s legacy makes every ownership transition fraught with meaning beyond money. A buy-sell agreement in a family business context must account for these dynamics—protecting the business from divorce, establishing fair resolution mechanisms for sibling disputes, and providing a clear path for generational transition. For more on this topic, see our guide to family business succession planning.
Employee Ownership Transitions
When the exit strategy involves selling to key employees or establishing an Employee Stock Ownership Plan, the buy-sell agreement must coordinate with the employee transition plan. The agreement governs what happens if the owner dies or becomes disabled before the transition is complete—ensuring the employee buyout can proceed even if the original timeline is disrupted. See our detailed guide on selling your business to employees.
Succession Planning Integration
The buy-sell agreement is one component of a broader succession plan. It must align with the owner’s estate plan, the business’s strategic plan, and the ownership transition timeline. An agreement drafted in isolation—without consideration of the owner’s will, trust, and overall exit strategy—creates conflicts that emerge at the worst possible time. Our business succession planning guide covers the full framework.
Tax Implications
The structure of the buy-sell agreement (cross-purchase vs. entity redemption) directly affects the tax treatment of the buyout for both the seller and the buyer. The choice between structures, the funding mechanism, and the pricing methodology all carry tax consequences that can amount to hundreds of thousands of dollars. These implications must be analyzed in the context of the owners’ overall tax situation. For a comprehensive treatment, see our guide to tax planning for business exits.
Updating Your Buy-Sell Agreement
A buy-sell agreement is not a document you sign once and file away. It is a living instrument that must be reviewed and updated regularly to remain effective. An outdated agreement is often worse than no agreement at all—it creates false confidence that a plan is in place while the actual terms no longer reflect reality.
The Five Triggers for Updating
Ownership change. Any time an owner joins or leaves the business, the agreement must be updated. New owners must be added as parties. Departing owners must be removed. Ownership percentages must be recalculated. Insurance policies must be adjusted.
Valuation change. If the business has grown (or declined) significantly since the last valuation was set, the pricing mechanism needs updating. This is particularly critical for agreements with fixed-price provisions, but even formula-based agreements should be reviewed to ensure the formula still produces a reasonable result.
Life event. Marriage, divorce, serious illness, or the birth of children can all affect an owner’s estate plan and risk profile. A life event for any owner is a prompt to review the agreement—particularly the trigger events and beneficiary designations on insurance policies.
Law change. Tax laws, state business entity statutes, and insurance regulations change. The 2017 Tax Cuts and Jobs Act, for example, significantly altered the tax landscape for business owners and made many existing buy-sell agreements suboptimal from a tax perspective. Changes in Minnesota law regarding LLCs, corporations, or estate taxes may also warrant revisions.
Business change. A material change in the business—entering a new market, acquiring another company, taking on significant debt, adding a line of business—changes the risk profile and the value of the enterprise. The buy-sell agreement should reflect the business as it exists today, not as it existed when the agreement was signed.
The Annual Review Meeting
The most effective approach is a scheduled annual review—a brief meeting among the owners and their advisors to confirm that the agreement’s terms, pricing, and funding remain current. Three questions: Has anything changed? Does the stated value still reflect reality? Are the insurance policies adequate? Most years, no changes are needed. But the years when they are, this meeting prevents the outdated-agreement problem that generates the majority of buy-sell disputes.
Frequently Asked Questions
Do I need a buy-sell agreement if I am the sole owner?
Not in the traditional sense—a buy-sell agreement requires at least two parties. However, sole owners face a related problem: what happens to the business if you die or become disabled? The answer lies in your estate plan and succession plan, not a buy-sell agreement. Designate a successor, ensure your personal representative has authority to manage or sell the business, and document the plan. See our business succession planning guide for the framework.
How much does a buy-sell agreement cost?
For a straightforward two-owner agreement, legal fees typically range from $2,500 to $7,500. Complex multi-owner agreements with detailed valuation provisions can cost $10,000 to $20,000 or more. In every case, the cost is a fraction of what a disputed ownership transition costs in litigation—which routinely exceeds six figures.
Can a buy-sell agreement prevent my partner from selling to a stranger?
Yes—this is one of the primary functions. A well-drafted agreement includes a right of first refusal: before an owner can sell to a third party, they must first offer their interest to the remaining owners (or the entity) on the same terms. Most agreements go further, requiring the consent of all or a majority of owners before any transfer to an outsider. These provisions keep ownership within the existing group and prevent unwanted third parties from acquiring an interest.
What happens if we do not have a buy-sell agreement and an owner dies?
The deceased owner’s interest passes according to their will or, if they had no will, according to state intestacy law. The remaining owners have no automatic right to purchase the interest. The estate (or the heirs) becomes a new owner of the business with all the rights that entails—including the right to vote, receive distributions, and participate in management decisions. The surviving owners may find themselves in business with someone they did not choose and cannot remove.
How often should we update our buy-sell agreement?
At minimum, review the agreement annually and update it whenever a significant change occurs—in ownership, business value, an owner’s personal circumstances, or applicable law. The most important element to keep current is the pricing mechanism. An agreement with an accurate, up-to-date price is enforceable and useful. An agreement with a price that was set a decade ago is an invitation to litigation.
Can a buy-sell agreement be overridden by a will?
No. A properly executed buy-sell agreement is a binding contract that takes priority over a will. When the agreement requires the estate to sell the deceased owner’s interest, the estate must sell—regardless of what the will says. The buy-sell agreement ensures the transition follows the plan the owners agreed upon, not any individual owner’s estate plan. However, the agreement must be properly executed and funded to be enforceable.
The Agreement That Pays for Itself
A buy-sell agreement costs a fraction of what a disputed ownership transition costs in litigation. More importantly, it preserves relationships, protects families, and ensures the business survives the transition. Every business with multiple owners will face a triggering event. The only variable is whether the owners planned for it or left the outcome to chance.
If your business has multiple owners and no current buy-sell agreement—or an agreement that has not been reviewed in years—the time to address it is now, while all owners are healthy, engaged, and able to negotiate in good faith. For a broader perspective on how a buy-sell agreement fits into your overall transition strategy, see our business succession planning guide, or explore related topics including business owner exit strategies, business valuation, and tax planning for business exits.
