Buy-Sell Agreements and Business Succession After Death or Disability

A buy-sell agreement is the contract that converts an ownership interest into cash when an owner dies, becomes disabled, quits, divorces, or is forced out. It answers three questions: what event triggers a purchase, who is obligated to buy, and how the price and payment are determined. Get one answer wrong and the other two stop working — a mandatory purchase at a formula price is worthless if nobody funded it, and a fully funded policy pays into the wrong hands if the structure was never matched to the funding.

These agreements are creatures of state law. Nothing below states a national rule.

Cross-purchase, redemption, and hybrid

Every buy-sell sits in one of three shapes. In a cross-purchase, the remaining owners buy the departing owner's interest personally. In a redemption (sometimes called an entity purchase), the company buys it back and the remaining owners' percentages rise automatically. A hybrid gives the company the first option and the owners the second, or the reverse, so the decision can be made when the trigger occurs rather than years in advance.

The basis point is the one owners most often miss. In a cross-purchase, the survivors have paid for what they now hold, and that cost reduces their gain on a later sale. In a redemption, the company spent the money and the survivors own a larger slice of the same asset with no additional basis. Over a long horizon and a successful exit, that difference is often larger than any premium savings that drove the original choice.

Funding by insurance and the Connelly problem

Most small-company buy-sells are funded with life insurance, because the cash need arrives on the same day as the death and no other source is that reliable. Disability buyouts are funded separately, with disability buyout policies whose definition of disability must be reconciled with the contract's definition — an agreement that triggers on inability to perform the owner's own occupation, funded by a policy that pays only on inability to perform any occupation, is a funding gap disguised as a funded plan.

In 2024 the Supreme Court decided Connelly v. United States, and it changed how redemption structures must be modeled. The case involved a closely held company that owned life insurance on its shareholders to fund a redemption obligation. The estate argued that the obligation to redeem offset the insurance proceeds, so the proceeds did not increase the company's value. The Court unanimously rejected that treatment: for federal estate-tax purposes, the proceeds were an asset of the corporation and the redemption obligation did not reduce the company's fair market value. The estate's shares were therefore valued in a larger company than the parties had planned around.

The practical consequences are concrete. A redemption funded by company-owned insurance can inflate the taxable value of a deceased owner's interest, producing an estate-tax bill computed on a value the family never receives. Alternatives exist and each has its own cost: shifting to a cross-purchase, holding the policies in a separate insurance limited liability company or partnership so that proceeds are not company assets, or accepting the structure and sizing the coverage to the larger number. Converting existing company-owned policies to individual owners is not a paperwork step either — the transfer-for-value rule can turn otherwise tax-free death benefits into taxable income unless a statutory exception applies, and a transfer to a fellow shareholder is not automatically within those exceptions.

Verify before relying: Connelly was decided in 2024 and planners are still working through its application to hybrids, partnerships, and existing policy portfolios. Any agreement drafted before that decision should be re-modeled with current tax counsel rather than assumed to still work.

Setting a price that survives the trigger

Three families of price mechanism dominate, and each fails in a predictable way.

1. Agreed value

   The owners state a number and promise to update it annually on a certificate signed by all of them. It is simple, cheap, and usually stale — the certificate is refreshed twice and then forgotten for nine years. Any agreement using this method needs a fallback that engages automatically once the stated value passes an age limit.

2. Formula

   A multiple of earnings, a capitalization of cash flow, book value, or a blend. Fast and predictable, but formulas drift from reality as the business changes shape. Define every input precisely: which earnings measure, which periods, how owner compensation is normalized, how debt and excess cash are treated.

3. Appraisal

   An independent valuation as of the trigger date. Most accurate, slowest, most expensive. Specify appraiser qualifications, who selects and pays, the standard of value, whether minority and marketability discounts apply, and a tie-break if each side appoints its own expert.

4. The discount question

   Decide in the contract whether a departing owner's minority interest is priced with discounts or as a proportionate share of enterprise value. Leaving it silent guarantees the dispute, because the answer can move the price by a third.

A buy-sell price also does not automatically control for other purposes. For federal estate and gift tax valuation, a restriction or option can be disregarded unless it satisfies statutory conditions — a bona fide business arrangement, not a device to transfer value to family members for less than full consideration, and terms comparable to arm's-length arrangements. Regulations under that provision are more forgiving where a substantial share of the affected interests is held by people outside the transferor's family, which is why family businesses need to document the business rationale in a way unrelated co-owners never have to. Divorce courts and lenders may also reach their own valuation regardless of what the owners agreed among themselves.

Triggers, terms, and the mechanics that get skipped

• Trigger list: death, disability, retirement, voluntary withdrawal, termination of employment for cause and without cause, divorce, personal bankruptcy, loss of a required professional license, and involuntary transfer by creditor process.
• Mandatory versus optional purchase for each trigger, stated separately — many agreements make death mandatory and everything else an option, which is a deliberate choice, not an oversight to copy blindly.
• A definition of disability with an elimination period, a decision-maker, and an examination protocol, matched to the funding policy's own definition.
• Payment terms where insurance does not cover the price: down payment, note term, interest rate at or above the applicable federal rate, acceleration, and security.
• Subordination language, since a senior lender will usually refuse to let buyout payments jump ahead of its debt.
• Spousal consent and, in community-property states, treatment of the non-owner spouse's interest.
• Restrictive legends on certificates or equivalent notation in the entity's records, so a transferee is bound by the restriction.
• Coordination with the estate plan: wills, revocable trusts, and beneficiary designations must not direct the interest somewhere the buy-sell forbids.
• An amendment procedure and a schedule for review — with a policy on whether changes may be made by written consent or require a meeting.

Governance is the quiet half of succession. If the departing owner was also the only signer on the bank accounts, the only person with the software credentials, or the sole manager under the operating agreement, the buyout provision does not keep the business running while the purchase closes. That is a records-and-authority problem, addressed in our brief on building a defensible corporate record. Majority owners negotiating with a deceased owner's family also owe duties under state law in many closely held entities, and a purchase on terms the majority set for itself invites a claim framed around the duty of loyalty.

Questions the desk gets

We have four owners. Is a cross-purchase still workable?

It is, but the policy count is the constraint: four owners insuring each other means twelve policies, with premiums varying by age and health. Beyond three or four owners, planners often use an insurance limited liability company or a partnership to hold one policy per owner while preserving cross-purchase treatment. That structure has its own formalities and its own tax traps, so it is a design decision to make with counsel and a tax adviser together, not a form to download.

Can the company just promise to buy without funding it?

It can, and unfunded obligations are common. The risk is that the obligation matures exactly when the business is weakest — it has just lost an owner. State law also limits distributions and redemptions that would leave a company unable to pay its debts, so an unfunded redemption can be legally blocked precisely when the family needs the money. If funding is not possible, say so in the document and use an installment note with realistic terms rather than a promise nobody can perform.

How is this different from the earnout in a sale?

A buy-sell governs an internal transfer among existing owners on a triggering event. An earnout is deferred purchase price in a sale to an outside buyer, contingent on post-closing performance. They share a problem — both depend on a number computed after the fact — and the drafting discipline transfers directly. Our brief on earnout metrics, control, and dispute risk covers that measurement problem in detail.

Who enforces the agreement if the surviving owners simply do not pay?

The deceased owner's estate does, through the executor, in state court. That is why the executor needs a copy of the agreement, the valuation certificates, and the insurance details in the estate file from day one. The duties that executor owes while pursuing the claim are covered in our brief on fiduciary duties of executors and trustees.

Where the risk actually sits

The risk is almost never in whether an agreement exists. It sits in the seams: a price mechanism that was current in a different business, insurance sized to a valuation from three growth cycles ago, a redemption structure chosen before the 2024 valuation ruling, or an estate plan that leaves the interest to someone the agreement will not let hold it. A review cycle that touches all four at once — every two or three years, and immediately after any material change in ownership, debt, or value — is what keeps the document connected to the company it governs.
