What is a buy-sell agreement and why do partners need one?
A buy-sell agreement is a written contract among business partners that fixes what happens to an owner's interest when that owner dies, becomes disabled, divorces, or wants to leave — who buys, at what price, and with what money. Without one, a surviving partner can inherit a stranger as a co-owner. An attorney drafts it, insurance usually funds it, and it is revisited whenever the valuation changes.
Key points
- A buy-sell agreement is a contract among business owners that fixes in advance who buys a departing owner's interest, at what price, and with what money.
- The agreement covers death, disability, divorce, and voluntary exit, the events that otherwise leave partners co-owning the business with an heir or a former spouse.
- Valuation is set by a formula, a stated value updated periodically, or an independent appraisal, and must be revisited as the business changes.
- Life insurance commonly funds a buyout on death and disability coverage funds a buyout on disability, so the money exists when the trigger occurs.
- Under section 2703, a buy-sell price is respected for estate-tax valuation only when the agreement is a bona fide business arrangement with arm's-length terms.
What does a buy-sell agreement decide?
A buy-sell agreement is a contract among the owners of a business that decides, in advance, what happens to an owner's share when a major life event occurs. It answers three questions before the event happens: who is allowed or required to buy the departing owner's interest, at what price, and with what money.
The triggering events are the ones that otherwise cause chaos: an owner dies, becomes disabled and can no longer contribute, divorces so that part of the interest is at issue in the settlement, or simply wants out with no agreed way to price or fund the exit. Each can pit partners against a departing owner's family or against each other at exactly the moment goodwill is thinnest.
What happens to partners without one?
Without an agreement, the default outcomes are usually bad. A surviving partner can find themselves co-owning the business with a deceased partner's heirs, effectively inheriting a stranger as a business partner. A divorcing partner's former spouse can end up with a claim on the company. When someone wants to leave, the absence of an agreed price turns the exit into a negotiation or a lawsuit.
The buy-sell agreement replaces all of that with a plan the owners chose while they were still on the same side.
How is the price set and the buyout funded?
The agreement should state how the interest is valued: a set formula, a stated value updated periodically, or an independent appraisal at the time of the event. A method everyone agreed to in advance is far easier to accept than a number argued over after a death or a split. Because business value changes, the agreement and its valuation should be revisited regularly.
Funding is the other half. An agreement that requires a buyout but provides no money is half a solution. Life insurance commonly funds a buyout on death, and disability coverage can fund a buyout on disability, so the money is available when needed without draining the business. The two common designs are a cross-purchase, where each owner holds a policy on the others, and an entity redemption, where the company holds the policies and buys back the interest. The choice affects the surviving owners' tax basis and, after the Supreme Court's Connelly decision, whether the insurance proceeds increase the company's value for estate tax.
What are the limits of a buy-sell agreement?
An agreement cannot fix a price the IRS must accept for estate-tax purposes unless it meets the tests in section 2703: a bona fide business arrangement, not a device to pass the interest to family members for less than full value, and terms comparable to what unrelated parties would agree. A stale valuation or an unfunded obligation makes the agreement weak exactly when it is needed.
An attorney drafts the agreement, because the terms, the triggers, and the valuation mechanics must fit the entity and the owners. An insurance professional arranges the funding. A CPA models the tax effect of the buyout and helps set a defensible valuation method. Put it in place while the partners are healthy and aligned, then revisit it as the business grows.
