Most business owners know they need a buy-sell agreement.
Far fewer have one that is funded.
And almost none have modeled what actually happens if a partner dies and the only plan is a document with no money behind it.
The answer is not pleasant. It involves the deceased partner’s spouse – who likely knows nothing about running the business – becoming your new business partner. It involves lawyers arguing over valuation. It involves your operational cash flow redirected to resolve an estate dispute. And in the worst cases, it ends with a forced sale of a business that could have been preserved.
This is not a theoretical risk. It is one of the most common and most avoidable business failures in America.
What a Buy-Sell Agreement Is – and What It Is Supposed to Do
A buy-sell agreement is a legally binding contract between the owners of a business that governs what happens to each owner’s interest in the event of a triggering event – typically death, permanent disability, voluntary exit, divorce, or bankruptcy.
In plain terms: it answers the question, “If you die, who buys your share, at what price, and with what money?”
Without a buy-sell agreement, the answer to that question is determined by state law, probate court, and the deceased owner’s estate – not by you, not by your remaining partners, and not by the interests of the business.
With a buy-sell agreement, the answer is determined in advance, in writing, by the people who built the business.
But a buy-sell agreement is only a legal framework. The funding is what makes it executable.
The Three Types of Buy-Sell Structure
Before discussing funding, it is useful to understand the basic structures:
Cross-purchase agreement. Each owner agrees to buy the other owner’s interest in the event of a triggering event. If there are two partners with a 50/50 split, each holds a life insurance policy on the other. When one partner dies, the surviving partner uses the death benefit to purchase the deceased partner’s interest from the estate. In a two-partner arrangement, this is clean and effective. With three or more partners, the number of policies grows quickly and administration becomes more complex.
Entity-purchase (or redemption) agreement. The business itself agrees to purchase the deceased owner’s interest from the estate. The business holds a life insurance policy on each owner. The business receives the death benefit and uses it to buy the interest back. This simplifies policy administration but has different tax implications for the surviving owners, who do not receive a step-up in their ownership basis under this structure.
Hybrid (wait-and-see) agreement. Provides flexibility – at the triggering event, the business has the first right of purchase, followed by the surviving owners. This allows the parties to choose the most tax-advantageous structure at the time of the event rather than in advance.
The right structure depends on the number of owners, the nature of the business, and the tax situation of the owners and the entity. A properly structured agreement coordinates the legal document with the tax strategy from the outset.
What “Unfunded” Actually Means in Practice
An unfunded buy-sell agreement is a document that says: “When Partner A dies, Partner B agrees to buy A’s 50 percent interest for $1.5 million within 90 days.”
If Partner B does not have $1.5 million in cash available within 90 days, the agreement is unenforceable in practice. Partner B may attempt to borrow the money – but a business owner who just lost a co-founder, is managing operational disruption, and suddenly needs $1.5 million is not an ideal borrower.
The estate, meanwhile, has its own timeline. Beneficiaries may need liquidity. If the estate cannot complete the sale within the contractual window, the agreement may be breached or renegotiated – at a time of maximum vulnerability.
In many cases, the surviving owner ends up in one of three situations:
Situation one: Forced partnership with the estate. If no sale occurs, the deceased owner’s interest passes to their heirs. The surviving business owner is now in a business relationship with the deceased partner’s spouse, adult children, or estate trustee – people who may have no understanding of the business, conflicting goals, and no legal obligation to be cooperative.
Situation two: Forced sale of the business. The estate may petition for a court-ordered valuation and forced sale to obtain liquidity. In this scenario, a business built over decades is sold under distress, at a price determined by a court, not by the market.
Situation three: Drawn-out legal dispute. Valuation disagreements between the surviving owner and the estate are common. The process takes years, costs hundreds of thousands in legal fees, and may permanently damage business relationships, client relationships, and the business’s value.
All three outcomes are avoidable with a funded plan.
How Life Insurance Funds the Agreement
Life insurance is the most common and tax-efficient mechanism for funding a buy-sell agreement. Here is why:
The death benefit arrives exactly when needed – at the moment of the triggering event. It arrives as a lump sum. Under Section 101(a) of the Internal Revenue Code, life insurance death benefits are received income-tax-free by the beneficiary.
For a two-owner business valued at $3 million, a properly funded cross-purchase agreement requires two policies: a $1.5 million policy on Owner A held by Owner B, and a $1.5 million policy on Owner B held by Owner A. Annual premiums depend on the ages and health of the owners, but they are typically a fraction of the obligation they cover.
The alternative – attempting to borrow $1.5 million on demand – is exponentially more expensive and significantly less certain.
King Legacy Group structures funded buy-sell agreements using life insurance policies designed to provide the exact death benefit needed at the coverage amounts required, with premiums incorporated into the business’s financial plan.
Disability: The Trigger Nobody Plans For
Most business owners think about death when they think about buy-sell agreements. Disability is the trigger they almost universally overlook.
Statistically, a 45-year-old business owner is far more likely to experience a long-term disability – defined as a disabling condition lasting 90 days or more – than to die before age 65. The Social Security Administration estimates that approximately one in four workers who enter the workforce today will experience a disability before retirement age.
A partner who becomes permanently disabled and can no longer contribute to the business creates the same structural problem as a partner who dies: their interest remains, their entitlement to profits remains, and the surviving partners must carry the operational load without being able to redeploy the disabled partner’s equity.
A disability buy-sell rider – or a separate disability buyout policy – provides benefits that fund the purchase of a disabled partner’s interest after a defined elimination period, typically 12 to 24 months. Without this, the business faces an indefinite period of operating with a non-contributing owner whose interest cannot be resolved.
Business Valuation: The Question the Agreement Must Answer
A buy-sell agreement that specifies a purchase obligation but does not specify a valuation method is incomplete. When the triggering event occurs, the surviving owner and the estate will almost certainly disagree on value. That disagreement is resolved by courts, appraisers, and attorneys – expensively.
Three valuation methods are used in buy-sell agreements:
Fixed price. The partners agree in advance on a specific dollar value for the business. This is simple but becomes outdated quickly if the business grows significantly after the agreement is signed. Agreements using fixed price must be reviewed and updated regularly.
Formula. A formula is agreed upon in advance – typically a multiple of earnings, revenue, or book value. This adjusts automatically as the business grows but may produce a value that does not reflect true market worth at the time of the event.
Independent appraisal. The agreement specifies that a professional business valuation will be conducted at the time of the triggering event by a mutually agreed-upon independent appraiser. This produces the most accurate value but introduces a process that takes time and cost.
For most small and mid-sized businesses, a hybrid approach – formula-based with a periodic independent appraisal as a check – provides accuracy and administrative simplicity.
Case Study: The Business That Could Not Be Saved
Two partners, both age 51, co-own an $8 million professional services business. They signed a buy-sell agreement nine years ago. It specifies that if either partner dies, the other buys the deceased partner’s 50 percent interest at a fixed price of $2 million – the value of the business at the time the agreement was signed.
The business has grown to $8 million in value since then. The fixed price was never updated.
Partner A dies unexpectedly. His estate – managed by his spouse, who is not involved in the business – reviews the agreement and recognizes that the $2 million fixed price significantly undervalues a $4 million interest (50 percent of $8 million).
The estate refuses to complete the sale at $2 million. Partner B cannot produce $4 million in cash within 90 days, and banks are cautious about lending against a business in transition. After 14 months of legal dispute, the business is sold to a third party at $6.5 million – below market because the dispute and management instability depressed buyer confidence.
Partner B nets $3.25 million from the forced sale instead of continuing to own a growing business. Partner A’s estate nets $3.25 million instead of the $4 million a properly structured buyout would have produced.
Both parties lost. The business lost. An updated agreement, funded by life insurance at current value, would have prevented all of it.
Frequently Asked Questions
Do I need a buy-sell agreement if I am the sole owner?
A buy-sell agreement applies to businesses with multiple owners. If you are the sole owner, the relevant documents are a succession plan, a will, and potentially a trust – specifying who inherits or takes over the business at death or disability. Key person insurance remains relevant even in a sole-owner business, as it protects the business from the financial impact of losing a critical employee.
How often should a buy-sell agreement be reviewed?
At minimum, every two to three years or after any significant business event: a substantial increase in revenue, a new financing round, a new partner, a significant asset acquisition, or a change in ownership structure. The valuation method or fixed price must be updated to reflect the current business value, or the agreement creates a trap for whoever ends up on the short end of an outdated valuation.
Can the business pay the life insurance premiums for a cross-purchase agreement?
In a cross-purchase agreement, the policies are held by individual owners, not the business. Premium payments made by the business on behalf of the owners are generally treated as compensation and are taxable to the recipient. There are specific structuring options – including corporate-owned life insurance and executive bonus arrangements – that allow business-paid premiums with different tax treatments. The right approach depends on the structure of the agreement and the business entity.
What if my business partner is uninsurable due to a health condition?
This is a real planning gap. If a partner cannot qualify for life insurance due to a health condition, the agreement should account for alternative funding mechanisms: a sinking fund (a dedicated account where the business deposits funds over time specifically to fund a potential buyout), a third-party loan commitment, or a staged payout structure in the agreement itself.
What is the difference between key person insurance and a buy-sell funding policy?
Key person insurance is a policy owned by the business on the life of a valuable employee or owner. The death benefit is paid to the business and is used to offset the financial loss of losing that person – recruiting replacement talent, managing client transitions, covering temporary revenue loss. A buy-sell funding policy is specifically structured to provide the cash needed to execute the ownership transfer at the agreed price. The two serve different functions and are often held simultaneously.
