Buy-Sell Agreements: How to Protect Your Ownership Before You Need To
The most dangerous document a multi-owner business can be missing is a buy-sell agreement. Not because it is complex, but because the moment you need one — a death, a divorce, a partner who stops showing up — you are out of time to negotiate it from a position of mutual goodwill. Without one, the courts, the default state rules, and whatever goodwill is left in the relationship decide what happens to your company.
A buy-sell agreement is a binding contract among co-owners that defines exactly what happens to an owner's equity stake when a triggering event occurs. It answers the questions that feel uncomfortable to ask when everyone is happy and the business is growing: What happens if one of us dies? What if one of us wants out and the other does not? What if one of us goes through a divorce and the ex-spouse ends up owning a piece of the business? What if we deadlock and cannot agree on a major decision? A good buy-sell agreement answers all of those before any of them happen — when everyone still wants the same outcome.
Every closely-held business with more than one owner should have one. Most do not. And many of the ones that do signed it once, never reviewed it, and are operating on terms that no longer reflect the business's value or the owners' intentions.
What every multi-owner business needs to understand about buy-sell agreements:
- The triggering events define what the agreement actually covers — and omissions are dangerous. A complete buy-sell agreement addresses death, permanent disability, voluntary exit (one partner wants to sell their stake), involuntary transfer (divorce, bankruptcy, creditor judgment), retirement, and deadlock. Each trigger has its own mechanics: who can buy, at what price, on what timeline, with what funding source. Agreements that cover only death leave the business exposed to every other scenario. Disability-only agreements that exclude divorce have been unwound by family courts. The triggering event list is not a formality — it is the entire operational content of the document.
- Cross-purchase vs. entity-redemption structures have meaningful tax differences. In a cross-purchase structure, surviving or continuing owners buy the departing owner's equity directly. In an entity-redemption (or stock-redemption) structure, the company itself buys back the equity. The cross-purchase structure generally produces a stepped-up tax basis for the buying owner — which reduces their capital gains tax when they eventually sell. The entity-redemption structure is simpler when there are many owners (fewer policies to maintain) but does not provide the same basis step-up. The right structure depends on the owners' anticipated exit timeline and tax situation. Choosing without running the tax math is common and expensive.
- Valuation method is the most contested part of any buy-sell — and the most often done wrong. There are three approaches: a fixed price agreed at signing, a formula (typically a multiple of EBITDA or book value), and an independent appraisal triggered at the event. Fixed price is the simplest and becomes wrong fastest — a business worth $2M when the agreement is signed may be worth $8M five years later, and the fixed price leaves the selling party with a bad deal. Formula-based valuations are better but must be calibrated to the industry. Independent appraisal at the trigger event is most accurate but also most likely to generate disputes between competing appraisers. Many well-drafted agreements use a formula with a floor and a mechanism for resolving appraisal disputes.
- Disability as a trigger is the most mechanically complex. Unlike death, where the trigger is unambiguous, disability requires defining what "disabled" means for purposes of the buyout. Is it any inability to work, or is it a defined percentage of time? For how long must it persist before the trigger fires — six months, twelve months? Who makes the determination — the owner's physician, an independent physician, a panel? What is the source of funds for the buyout, since life insurance does not apply? Getting the disability definition and the mechanics right requires specific legal drafting, and most off-the-shelf buy-sell templates do this part poorly.
- Life insurance is the most common funding mechanism — and it works well when designed correctly. A death trigger with a life insurance policy on each owner sized to fund the buyout is the most reliable and tax-efficient solution for the death scenario. In a cross-purchase structure, each owner owns a policy on each other owner. In an entity-redemption structure, the company owns a policy on each owner. The policy face value should be reviewed annually and updated as the business grows — a policy sized to a $1M valuation cannot fund a $4M buyout. Stale insurance is almost as bad as no insurance.
- The "Russian roulette" clause is a real and sometimes appropriate deadlock mechanism. In a deadlock scenario between equal partners who cannot agree on the business's direction, some buy-sell agreements include a forced-sale provision: one owner names a price, and the other owner must either buy at that price or sell at that price. The elegant cruelty of the mechanism is that the naming party has no way to name an artificially low price — they might end up selling at it. It forces both parties to price the business honestly. Not appropriate for every partnership, but worth understanding as a tool for 50/50 structures where deadlock is a real governance risk.
- Divorce transfers create some of the messiest outcomes in closely-held businesses. When an owner goes through a divorce, the equity stake is often marital property subject to division. Without a buy-sell provision restricting the transfer of equity to non-owners, a divorcing owner's ex-spouse can end up as a co-owner — or a court can force a sale of the stake under terms the remaining owners cannot control. A well-drafted buy-sell agreement includes a provision requiring the divorcing owner's estate to trigger a buyout, with the proceeds (not the equity) going into the divorce settlement.
- Review and update intervals belong in the agreement itself. Most buy-sell agreements are signed once and never revisited. Values change, ownership percentages change, businesses add or lose owners, insurance policies lapse. Best practice is to specify in the agreement that the parties will review valuation methodology and insurance coverage annually, with a formal reconfirmation or update every three years. Owners who build the review schedule into the agreement are far more likely to have a document that actually works when it is needed.
What it costs to operate without a buy-sell agreement: co-owners resolved by family courts under state default rules, forced sales at whatever price litigation produces, and businesses that survive the triggering event financially but not operationally.
We help small business owners design buy-sell agreements that cover the triggering events that actually matter, fund the buyout correctly, and hold up when the conversation is no longer hypothetical.
