Buy-Sell Agreements and What Triggers Them

A buy-sell agreement decides in advance what happens to an ownership share when something goes wrong. It is the document that stops a dead partner's spouse from becoming your business partner, and it is the reason a disability does not force a fire sale. Most small businesses either do not have one, or have one that was signed years ago with a valuation clause nobody has looked at since. The second situation is often worse than the first, because everyone believes they are covered.

The five triggers

Death. The share passes to an estate, and without an agreement you can find yourself in business with heirs who have no interest in the business and every interest in being paid.

Disability. Harder than death, because the person is still there, still an owner, and no longer contributing. The agreement has to define disability precisely enough that the definition is not itself the dispute.

Divorce. A spouse can be awarded an interest in the business as marital property. A well-drafted agreement gives the company or the other owners the right to buy that interest back rather than accept a new co-owner.

Dispute. Owners who cannot work together need an exit route that is not litigation. Shotgun and forced-buyout clauses exist for exactly this.

Departure and retirement. The planned one, and the only one anyone thinks about when the agreement is drafted.

The valuation clause is where these fail

A fixed price written into the agreement and never updated. This is the most common failure by a wide margin. A number set eight years ago pays out a fraction of current value, or an unaffordable multiple of it, and either way somebody is badly hurt by a document they signed to protect themselves.

A formula that made sense once. Three times net income sounds durable until margins change, until the company takes on debt, or until an accounting policy shifts what net income means.

The workable approach is a defined process rather than a defined number: an independent appraisal at the time of the trigger, using a named standard of value and a named method for selecting the appraiser. Slower, and it produces a defensible number instead of an arbitrary one.

**If you write in a fixed price, put a review date in the same clause and actually keep it.** An annual or biennial refresh is the difference between a document that protects you and a document that misleads you.

Funding it, which is the part that gets skipped

An agreement that obliges the company or the surviving owners to buy a share, without a funding source, is a promise to find several hundred thousand dollars during the worst month of everyone's life. That is not a plan.

Life insurance is the usual answer for death. In a cross-purchase structure each owner insures the others and buys their share directly. In an entity redemption structure the company owns the policies and buys the share back. The two have different tax and basis consequences, and the right one depends on the number of owners and the entity type.

Disability buyout insurance covers the trigger nobody funds. It is less familiar than life cover and it is the gap that most often turns into litigation, because the disabled owner still needs income and the remaining owners still need to run the business.

Key man insurance is a related but different instrument: it pays the company for the loss of a critical person, covering the disruption rather than funding the purchase of their share. Businesses that depend on one person often need both, and lenders sometimes require key man cover as a loan condition.

What happens without one

On a death, the share goes wherever the will or state law sends it. Heirs with no operating role hold a stake, expect distributions, and can block decisions depending on the entity documents.

On a dispute, your options narrow to negotiating from a weak position or litigating, and the value of the business degrades while that plays out.

On a divorce, an interest can be transferred to a former spouse with no obligation to sell it back.

In every one of these, the absence of an agreed valuation method means the number is negotiated under maximum pressure by people with directly opposed interests. That is precisely the situation the document exists to prevent.

Common questions

What is a buy-sell agreement?

A binding agreement among business owners setting out what happens to an ownership interest when a triggering event occurs: death, disability, divorce, dispute or departure. It typically covers who may or must buy, how the price is determined, how the purchase is funded and over what period it is paid.

How should a buy-sell agreement value the business?

Through a defined process rather than a fixed number. Name the standard of value, the valuation method and how the appraiser is selected, then have an independent appraisal performed at the time of the trigger. Fixed prices go stale, and formulas that once made sense stop making sense when margins, debt or accounting policies change. If you do write in a fixed price, put a mandatory review date in the same clause.

What is key man insurance and do I need it?

Key man insurance pays the company if a critical person dies or becomes disabled, covering the disruption to the business rather than funding the purchase of their ownership share. It is worth having where losing one person would materially damage revenue, and lenders sometimes require it as a condition of a loan. It complements a funded buy-sell agreement; it does not replace one.

What is the difference between a cross-purchase and an entity redemption?

In a cross-purchase, each owner holds policies on the others and buys the departing owner's share personally, which generally gives the buyers a stepped-up basis. In an entity redemption, the company owns the policies and buys the share back, which is simpler to administer with several owners but does not deliver the same basis benefit. The right structure depends on how many owners there are and on your entity type.

What happens if we do not have a buy-sell agreement?

On a death the interest passes to heirs who may have no interest in operating the business, and on a divorce it can be awarded to a former spouse. In a dispute your only routes are a weak negotiation or litigation while the business loses value. In all of them the price is negotiated under maximum pressure by people with opposed interests, which is exactly what the agreement exists to avoid.
