Buy-sell agreements and divorce: when the contract price controls
Long before anyone was divorcing, the owners wrote a formula: if a partner leaves, dies, or is bought out, the interest changes hands at book value, or a fixed multiple, or last year's appraisal. Now a marriage is ending, the interest is on the marital balance sheet, and one spouse is holding up the agreement like a price tag. Whether a divorce court honors that number — and what it takes for a contract price to earn real weight — turns out to have a surprisingly well-developed answer, much of it borrowed from tax law.
- The formula binds the owner, not the court. Most states treat a buy-sell price as evidence of value — sometimes strong evidence — but not a cap on what the marital estate is worth, especially against a spouse who never signed.
- Tax law supplies the framework courts borrow: Revenue Ruling 59-60 calls a restrictive agreement "a factor to be considered," and IRC section 2703 disregards below-market price restrictions unless the arrangement is bona fide, not a wealth-shifting device, and comparable to arm's-length terms.
- Three factors earn a contract price weight: negotiated at arm's length among unrelated owners, kept current, and actually used in real transactions.
- The restrictions still matter even when the price doesn't: transfer limits are real facts that feed marketability discounts — and the risk of a forced sale at the formula price is part of the economic picture.
What the agreement is — and what it was written for
Buy-sell provisions — in shareholder agreements, operating agreements, or standalone contracts — exist to keep ownership inside the group: they restrict transfers, give the company or co-owners first refusal, and fix a price or formula for buyouts on death, disability, departure, or sometimes divorce itself. They were written to prevent exactly the situation a divorce threatens: an outsider (here, an ex-spouse) holding an interest in a closely held company. That purpose is legitimate — and it is also why courts read the price term skeptically when it surfaces as valuation evidence: the people who set it had every incentive to keep buyout numbers low, and the person against whom it's now invoked had no seat at that table.
Why the price binds the owner but rarely the court
Divorce valuation asks what the interest is worth as marital property while the owner keeps it — restrictions and all — not what the owner would collect in a hypothetical buyout. Courts in most states therefore distinguish two questions the agreement answers differently. Between the owners, the contract price governs: if the triggering event happens, that's the deal. Between the spouses, the majority view treats the formula as evidence of value to be weighed with the appraisal approaches, not a conclusive cap — because a rule that let owners' side agreements fix the marital estate's value would invite every closely held company to adopt a lowball formula as divorce insurance. A minority of decisions have enforced agreement prices where the facts were clean; the pattern in those cases is exactly the three-factor showing below.
The tax-law framework courts borrow
Estate and gift tax confronted this problem decades before family law, and its answers travel well. Revenue Ruling 59-60, Section 8, holds that a buy-sell agreement "is a factor to be considered, with other relevant factors, in determining fair market value" — and pointedly, that "where the stockholder is free to dispose of his shares during life and the option is to become effective only upon his death, the fair market value is not limited to the option price." The ruling instructs examiners to ask whether the arrangement "represents a bonafide business arrangement or is a device" to pass value for less than full consideration.
Congress hardened that inquiry into statute. Under 26 U.S.C. §2703, property is valued "without regard to" any option, agreement, or right to acquire it at less than fair market value — unless the arrangement clears all three prongs of the exception: it is a bona fide business arrangement; it is not a device to transfer property to family members for less than full consideration; and its terms are comparable to similar arrangements struck at arm's length. Divorce courts are not bound by §2703, but the three-prong logic maps almost perfectly onto how they actually weigh buy-sell prices — which is why it's the best checklist either spouse can bring to the fight.
When the contract price earns real weight
- Arm's length. A price mechanism negotiated among unrelated owners with genuinely adverse interests — where every signer faced the same odds of being buyer or seller — carries the credibility a family-member formula never will.
- Kept current. A formula or standing appraisal updated on schedule tracks real value; a book-value clause untouched since the company's founding is a fossil, and courts treat it like one.
- Actually used. Nothing validates a price like history: if departing owners were genuinely bought out at the formula in real transactions, the number stops being theoretical. If the agreement has never been applied — or was waived whenever it pinched — its evidentiary value collapses.
For the non-owner spouse, each factor is a discovery target: who drafted the agreement and when, how the price was set, every amendment, and every transaction where it was applied, ignored, or renegotiated. For the owner, the same list is the proof package — assembled, ideally, years before anyone needed it.
The restrictions matter even when the price doesn't
Rejecting the formula price doesn't erase the agreement. Its transfer restrictions are real characteristics of the interest, and appraisers may reflect them in the marketability and control discounts — an interest nobody can sell without offering it to the company first at a formula price is genuinely less marketable than free shares. And the formula can cut the other way, too: if the owner could realistically be forced out at the contract price soon after the divorce, valuing the marital interest far above what the owner could ever collect builds an appeal into the judgment. The honest resolution is the one that runs through this whole subject: put the agreement in front of the appraiser, price its effects explicitly, and argue about the assumptions in the open — the same discipline that governs goodwill allocation and every other expert fight.
Frequently asked questions
Our operating agreement says my interest is worth book value. Is that what the court will use?
Probably not by itself. Most courts treat a buy-sell price as evidence of value rather than a ceiling, especially against a spouse who never signed it. A formula negotiated at arm's length among unrelated owners, kept current, and actually used in real buyouts earns real weight; a stale book-value clause among family members earns very little.
Why does the agreement bind the owner but not the court?
The agreement is a contract among the owners about what happens on a sale or exit. A divorce valuation is not a sale — the owner keeps the interest, restrictions and all — and the non-owner spouse was never a party. Courts reason that letting owners' side agreements cap a marital estate would invite lowball formulas as divorce insurance.
Does the buy-sell price at least matter for something?
Yes, twice over. It is evidence of value — stronger or weaker on the arm's-length, kept-current, actually-used factors — and its transfer restrictions are real facts that affect marketability, which appraisers may reflect in discounts. And if the owner could be forced to sell at the formula price soon, that risk belongs in the economic picture too.
We're about to sign a buy-sell agreement. Anything to do differently?
Treat the price mechanism as if a court will one day read it: use a formula or periodic appraisal that tracks real value, update it on schedule, and apply it consistently in actual buyouts. A current, arm's-length, consistently used price is the only kind that has ever persuaded courts — in divorce or in tax.
