What a Buy-Sell Agreement Should Actually Contain

The Most Important Document Nobody Reviews

A buy-sell agreement governs what happens to ownership when a triggering event occurs — death, disability, divorce, departure, or disagreement. It's the document that determines who can buy a departing owner's interest, at what price, and with what funding. For businesses with more than one owner, it's arguably the most important financial document in existence. And for businesses with a single owner, the absence of one creates a gap that affects estate planning, business continuity, and exit readiness.

The problem is not that business owners don't have buy-sell agreements. Most multi-owner businesses do. The problem is that the agreement was drafted when the business was worth a fraction of what it's worth today, using a valuation methodology that may no longer reflect reality, funded by insurance policies that may no longer be adequate, and containing trigger events that may not cover the scenarios most likely to occur.

A buy-sell agreement that was appropriate when the business had $800,000 in revenue is not appropriate when the business has $6 million in revenue. But most agreements are never updated — because updating them requires someone to initiate the financial analysis, and that rarely happens until a triggering event forces the conversation under pressure.

The Four Financial Elements That Need to Be Current

A buy-sell agreement contains both legal terms and financial terms. The legal terms — governing law, dispute resolution, restrictive covenants — are the attorney's domain. The financial terms are where the economic outcome is determined, and they require rigorous financial analysis. Four elements in particular need regular review.

1. The valuation methodology. How will the business be valued when a triggering event occurs? Many buy-sell agreements use a fixed price that was agreed upon when the agreement was signed — and never updated. Others use a formula (such as a multiple of revenue or earnings) that may not reflect current market conditions. The strongest approach is to require a formal valuation by a qualified appraiser at the time of the triggering event, with an agreed-upon standard of value (fair market value, fair value, or investment value) and a defined process for selecting the appraiser. Without a clear, current valuation methodology, the agreement becomes the starting point of a dispute rather than the resolution of one.

2. The pricing formula. Even with a sound valuation methodology, the pricing formula — how the valuation translates into a purchase price — needs to reflect reality. Does the price include a discount for minority interest? Is goodwill included? How are working capital adjustments handled? What happens to retained earnings or shareholder loans? These details seem technical until they determine a $500,000 difference in the purchase price. The pricing formula should be reviewed whenever the business's financial profile changes materially — a threshold most businesses pass every two to three years.

3. The funding mechanism. A buy-sell agreement that establishes a $4 million buyout obligation but provides no mechanism to fund it is a promise without substance. The most common funding mechanism is life insurance — typically cross-purchase policies or entity-redemption policies — sized to cover the expected buyout amount. But insurance coverage needs to keep pace with business value. A policy purchased when the business was worth $1.5 million doesn't fund a $4 million obligation. The gap between the insurance coverage and the buyout amount needs to be identified, quantified, and addressed — either through additional coverage, installment payment provisions, or alternative funding structures.

4. The trigger events. Death and disability are standard triggers in most agreements. But what about voluntary departure? Involuntary termination? Divorce? Bankruptcy of an owner? Retirement? A disagreement between partners that makes continued co-ownership unworkable? Each trigger event creates a different set of financial dynamics, and the agreement should address each one specifically. A voluntary departure at age 62 should not be handled the same way as an unexpected death at age 48 — but many agreements apply the same terms to both scenarios.

The Financial Stress Test

The simplest way to evaluate whether a buy-sell agreement is adequate is to stress-test it against a realistic scenario. Pick the most likely triggering event — for most businesses, that's the voluntary departure or retirement of one owner — and walk through the agreement as if it happened today.

What valuation would the agreement produce? Is that number consistent with what the business would sell for on the open market? If the formula produces $2.5 million but the business would likely sell for $4 million in a third-party transaction, the departing owner has a legitimate grievance — and the agreement may not survive a legal challenge.

Is the buyout funded? If the agreement requires the remaining owners to purchase the departing owner's interest, do they have the cash or insurance proceeds to do so? If not, what happens? Many agreements default to installment payments over five to ten years — but those payments need to be serviceable from the business's cash flow without impairing operations.

Does the agreement align with the exit plan? If an owner is planning to sell the entire business to a third party in three years, a buy-sell agreement that restricts the ability to sell — or that gives other owners a right of first refusal at a below-market price — can directly interfere with the exit strategy. The agreement needs to contemplate the planned exit and create a pathway that supports it, not one that blocks it.

Why This Is Financial Work, Not Just Legal Work

Attorneys draft buy-sell agreements. But the financial terms inside those agreements — valuation methodology, pricing formula, funding adequacy, and economic impact of trigger events — require financial analysis to get right. An attorney can draft language that says "the business will be valued using a multiple of trailing twelve-month EBITDA." But determining what that multiple should be, whether it reflects market reality, and how the resulting number interacts with the funding mechanism and tax implications — that's financial work.

This is why the buy-sell review should involve both legal counsel and financial advisory working together. The attorney ensures the legal terms are enforceable. The financial advisor ensures the economic terms are realistic. When these two disciplines work independently — which is common — the agreement looks legally sound but produces financial outcomes that nobody anticipated.
