When a co-owner of a private company dies, the family inherits shares in a business they may not understand and the surviving owners find themselves in partnership with people they did not choose. A buy-sell agreement settles that in advance. It is a contract that says who can buy the departing owner's stake, when and at what price.
Two basic structures
In a cross-purchase agreement, the surviving owners agree to buy the stake directly from the estate. In an entity-redemption agreement, the company itself buys it. Each has different tax and administrative consequences, and the right choice depends on how many owners there are, how the company is taxed and what the owners want. An attorney and an accountant should be part of that decision.
Why funding matters
An agreement that obliges someone to buy but gives them no money to do it is a promise that may not be kept. Life insurance is a common way to fund a purchase triggered by death: the policy pays at the moment the cash is needed, and the proceeds go to the buyer, who uses them to pay the estate. The family receives cash instead of an illiquid stake, and the surviving owners keep control.
Agreeing on value
The hardest clause is price. Some agreements fix a number and update it every year, some use a formula based on earnings or revenue, and some call for an independent valuation. A number set once and forgotten becomes unfair as the company grows. Whatever method you choose, review it regularly and make sure the insurance amount keeps pace.
Other triggers
Death is only one event. Good agreements also address disability, retirement, divorce, a dispute between owners and an owner who wants to leave. Some can be supported by disability buyout coverage, and some are handled by a payment schedule over time. Think through each case while everyone still gets along.
Keep it alive
A buy-sell agreement is not a document to sign and file away. Reread it every year or after a major change in ownership, value or tax rules. Confirm the policies are in force and the premiums are paid. Confirm the beneficiaries are the right ones. An out-of-date agreement can cause the very dispute it was meant to prevent.
