What Is a Buy-Sell Agreement and Why Do Business Partners Need One?
Last reviewed: July 2026
A buy-sell agreement is a legally binding contract between co-owners of a business that controls what happens to an owner's share if that owner dies, becomes disabled, retires, divorces, or otherwise exits. It sets the price, names who has the right to buy, and spells out how the purchase gets funded. Without one, partners are left improvising during a crisis, and improvisation around ownership tends to end in court. The whole point of a buy-sell agreement is to settle the hard questions while everyone is calm, healthy, and still on speaking terms.

About the Author: Jeff Judge, CFP®, AEP®, ChFC®, CLU® is Managing Partner of Chesapeake Financial Planners in Forest Hill, Maryland. He has been helping families and business owners in Harford County and the Baltimore metro area navigate business succession planning since earning his CFP® certification in 2013, by using Chesapeake Financial Planners’ signature process, the R.U.D.D.E.R. method™. Jeff has watched more than one strong partnership nearly unravel not because the business failed, but because the partners never agreed on what a departing owner's share was worth.
What Does a Buy-Sell Agreement Actually Do?
A buy-sell agreement is a contract that governs ownership transfers when a triggering event occurs. It answers the questions partners usually avoid until it is too late: What event forces a buyout? What is the ownership worth at that moment? Who has the right to buy the departing owner's interest? How does the buyer pay for it? What stops an owner from selling to an outside party the others never agreed to work with?
Think of it as a prenuptial agreement for a business. It protects every owner by establishing the rules before emotion, money, or a family member's grief clouds the decision. A well-drafted agreement removes guesswork and keeps a single bad day from becoming a years-long legal fight.
This is exactly the kind of decision the R.U.D.D.E.R. Method™, Chesapeake Financial Planners' six-step planning process of Review and Recognize, Uncover and Understand, Design and Develop, Discuss and Decide, Execute and Empower, and Reassess and Refine, is built to handle. A buy-sell agreement is not a one-time document; it needs review and reassessment as the business grows.
What Do Business Owners Most Often Forget to Plan Before Exiting?
What Events Trigger a Buy-Sell Agreement?
Most agreements address the events that financial planners often call the "Five Ds": death, disability, divorce, departure, and disagreement. Each one creates a moment where ownership could pass to someone the remaining owners never chose.
- Death. The agreement usually requires or permits surviving owners to purchase the deceased owner's interest, preventing heirs from becoming partners by default.
- Disability. Agreements often include a waiting period of six to twelve months before triggering a buyout, giving the disabled owner time to recover.
- Retirement. The contract sets how and when a retiring owner exits and which valuation method applies.
- Voluntary departure. Most agreements grant remaining owners a right of first refusal before an owner can sell to anyone outside.
- Divorce. A buy-sell provision can require an owner to buy their own shares back from an ex-spouse, keeping the former spouse out of the business.
- Bankruptcy. The agreement can let remaining owners purchase shares before creditors can seize them.
Jeff Judge often tells business owner clients that the divorce trigger is the one partners underestimate most. A partner's marriage is outside the business, but in many states a business interest is marital property, and without a buy-sell clause an ex-spouse can end up holding equity in a company they have never worked a day in.
What Are the Two Main Types of Buy-Sell Agreements?
The two structures business partners use most are the cross-purchase agreement and the entity purchase agreement. They differ in who buys the departing owner's interest and how the tax math works.
| Feature | Cross-Purchase Agreement | Entity Purchase Agreement |
|---|---|---|
| Who buys the shares | The remaining individual owners | The business entity itself |
| Number of life insurance policies | One per owner pair (grows quickly) | One per owner, owned by the entity |
| Cost basis step-up for buyers | Yes, buyers get a stepped-up basis | No basis increase for surviving owners |
| Best fit | Two or three owners | Businesses with several owners |
A cross-purchase agreement works cleanly when there are only a few owners. With five owners, though, funding it with life insurance can require up to twenty separate policies, which is why larger groups often choose an entity purchase or a hybrid structure. The right choice depends on the number of owners, the entity type, and the tax position of each owner, so this is a conversation to have with both a tax advisor and a financial planner.

How Is a Buy-Sell Agreement Valued and Funded?
Valuation is the single most contentious issue in any buy-sell agreement, and it is where partnerships without a written method end up in litigation. The agreement should lock in how the price gets set long before anyone needs the answer.
Common valuation approaches include a fixed price the owners update annually, a formula such as a multiple of EBITDA or book value plus a goodwill factor, and an independent appraisal performed when a triggering event occurs. According to SCORE, a professional business valuation can range from a few thousand dollars to $40,000 or more depending on the company's size and complexity. A fixed price is simple but goes stale fast; an appraisal is accurate but slow and costly. Many well-built agreements use a formula as the default and allow an independent appraisal if the owners disagree by more than a set percentage.
Funding matters just as much as price. The most common funding method is life insurance, where the policy death benefit provides immediate cash to buy out a deceased owner's interest without draining the business. Disability buyout insurance can fund the disability trigger. Other options include an installment note paid over several years or a sinking fund the business builds over time. According to the IRS, the way ownership is held affects how transfers are taxed, so the funding method and the entity structure should be planned together.

Frequently Asked Questions
What is a buy-sell agreement in simple terms?
A buy-sell agreement is a written contract among business co-owners that decides what happens to an owner's share when that owner dies, becomes disabled, divorces, retires, or leaves. It sets the price, names who can buy the share, and spells out how the buyout is funded, so the remaining owners are not forced into a crisis decision.
Who needs a buy-sell agreement?
Any business with more than one owner needs a buy-sell agreement, including partnerships, multi-member LLCs, and closely held corporations. The agreement protects every owner from being forced into business with an outside party such as a deceased partner's heirs or an ex-spouse. Even family businesses benefit, because family relationships do not prevent ownership disputes after a death.
How much does a buy-sell agreement cost to set up?
Drafting a buy-sell agreement typically involves attorney fees that vary by complexity and the number of owners, plus the cost of funding it. The largest ongoing cost is usually funding, often through life insurance premiums or a periodic business appraisal. According to SCORE, an independent valuation alone can run from a few thousand dollars to $40,000 or more.
What is the difference between a cross-purchase and an entity purchase agreement?
In a cross-purchase agreement, the remaining individual owners buy the departing owner's interest directly, and they receive a stepped-up cost basis. In an entity purchase agreement, the business itself buys back the interest, which simplifies life insurance because the entity owns one policy per owner. Cross-purchase suits two or three owners; entity purchase suits larger groups.
How is a business valued in a buy-sell agreement?
A buy-sell agreement values the business using one of three common methods: a fixed price the owners update annually, a formula such as a multiple of earnings, or an independent appraisal performed when a triggering event happens. Many agreements use a formula as the default and add an appraisal option if owners disagree by more than a set percentage, balancing speed and accuracy.
Ready to Protect What You Built?
