Business Valuation for Divorce: How a Business Is Valued, What It Costs, and Who Can Sign the Report

A business valuation for divorce determines what a marital interest in a company is worth so the court or the settlement can divide it. A credentialed appraiser (ABV, CVA, or ASA) normalizes the owner's compensation, applies income, market, and asset approaches as of a court-approved valuation date, separates enterprise goodwill from personal goodwill, and issues a written report they can defend under cross-examination. A full divorce valuation typically costs $3,500 to $15,000 or more per side, and the number moves substantially depending on the state's standard of value.

This is general information for business owners and their advisors, not legal advice. Family law is state law, and two owners with identical companies in different states can end up with materially different numbers. Talk to a family law attorney in your state, and expect the court to want a credentialed appraiser rather than a spreadsheet.

How is a business valued in a divorce?

The appraiser applies the same three approaches used in any valuation, then adjusts for the rules of the family court. The income approach capitalizes normalized earnings or discounts projected cash flow. The market approach compares the company to actual transactions. The asset approach nets assets against liabilities. The appraiser weights them and concludes a value as of a specific date.

Divorce work diverges from sale-side work in everything around the arithmetic. In a sale, the number is a negotiating position and the market settles it. In a divorce, the number is evidence, and it has to survive a rebuttal expert and a judge who has seen a hundred of these.

The earnings work itself is familiar. Recast the profit and loss to remove personal expenses run through the company, add back the owner's compensation above what it would cost to hire a manager to do the job, strip out one-time items, then capitalize what remains. Normalizing that salary is often the most contested single line: set it too low and the business looks more profitable than it is, set it too high and the value collapses. A discounted cash flow analysis serves as the cross-check, particularly for professional practices where projected earnings drive most of the value.

What standard of value is used in a divorce?

It depends on the state. Most states apply fair market value, the price a hypothetical willing buyer would pay a hypothetical willing seller, both informed and neither compelled. A meaningful minority apply fair value, a statutory standard that generally does not allow the same discounts and is closer to a proportionate share of total enterprise value.

The difference is not academic. Under fair market value, a 40 percent interest in a closely held company may be discounted for lack of control and lack of marketability, sometimes reducing the indicated value by 25 to 40 percent in combination. Under fair value, those discounts are frequently disallowed, and the same interest is worth 40 percent of the whole. On a $4M company, that gap is over $500,000 of divided property.

Some states use neither cleanly and apply an intrinsic "value to the holder" standard, asking what the business is worth to the spouse who keeps operating it. Your attorney should tell you which standard your court uses before the appraiser starts work, because it changes the assignment.

What is the valuation date in a divorce?

The valuation date is the single day the business is valued as of, and states set it differently: the date of separation, the date the petition was filed, the date of trial, or a date the judge selects. Everything after that date is generally ignored, which is why the choice of date is litigated on its own.

Consider a contractor whose backlog doubled in the eighteen months between separation and trial. Under a separation-date rule that growth belongs to the operating spouse; under a trial-date rule a share of it is on the table. The reverse happens too, when a business loses its largest customer after separation.

Is my business marital property?

Usually at least partly, even if you started it before the marriage and your spouse never worked in it. A business founded during the marriage is generally marital property in full. A business owned before the marriage is typically separate property as to its premarital value, but the increase in value during the marriage may still be divisible depending on why it increased.

That last point is the active versus passive appreciation analysis, and it is where a lot of the expert work goes. Active appreciation, growth driven by the owner spouse's labor, management, or reinvested marital earnings, is commonly treated as marital. Passive appreciation, growth from inflation, market movement, or a real estate holding that appreciated on its own, is more often separate. Appraisers are frequently asked to value the company twice, at the date of marriage and at the valuation date, then allocate the difference between active and passive causes.

What is the difference between personal goodwill and enterprise goodwill?

Enterprise goodwill belongs to the business: the brand, the location, the systems, the trained staff, the customer list that stays put when the owner leaves. Personal goodwill belongs to the individual: their reputation, skill, and personal relationships, which walk out the door with them. Many states exclude personal goodwill from the marital estate entirely.

The reasoning behind exclusion is that personal goodwill is really future earning capacity, already addressed through spousal support, and counting it again as property would divide the same asset twice. States including New Jersey, California, Minnesota, and, since a 2024 statutory amendment, Florida exclude personal goodwill in some form, while New York has historically taken a broader view. Case law keeps moving, so verify the current rule in your jurisdiction.

This matters most for professional practices and owner-operator service businesses. A dental practice with three associates, a strong location, and a twenty-year patient base has substantial enterprise goodwill. A solo consultant billing $700,000 a year off personal relationships may have almost none, and in a state that excludes personal goodwill, a well-supported appraisal can conclude that the divisible value is close to the equipment and receivables. Expect that position to be contested hard.

How much does a divorce business valuation cost?

Expect $3,500 to $15,000 or more for a defensible divorce valuation, and materially more when the case goes to trial with depositions and rebuttal testimony. Litigation work carries a premium of roughly 1.5x to 2x over a comparable non-litigation valuation, because the deliverable has to withstand adversarial review rather than simply inform a decision.

Two variables drive most of the spread: how clean your books are and how contested the case is. A single-entity company with reviewed statements sits at the low end. Three related entities, cash-intensive operations, and a spouse alleging unreported income sit at the high end, and forensic accounting may be a separate engagement. Our breakdown of what a business valuation costs covers how those variables play out in non-litigation work.

Should we hire one joint appraiser or each hire our own?

A single joint neutral appraiser, agreed to by both attorneys, is cheaper and usually faster, and it removes the spectacle of two credentialed experts reaching numbers that differ by a factor of two. Each side hiring its own expert costs more but preserves the right to advocate a position and to attack the other side's assumptions.

Joint neutrals work well when both spouses trust the process and the goal is a negotiated settlement. They work badly when one spouse controls the books and the other has no visibility into them, because the neutral can only analyze what they are given. In that situation the out-spouse usually needs their own expert with discovery behind them.

Who does the appraiser work for?

A credentialed appraiser's opinion is independent regardless of who signs the engagement letter. They are hired by a party or jointly by both, often through counsel so the early work sits under attorney work product, but professional standards require that the conclusion not be contingent on the outcome or on who is paying. An appraiser who shades a number to please the client is risking their credential.

Legitimate advocacy is emphasis: which assumptions to test hardest, which comparable transactions are truly comparable, whether a discount is supportable. Two honest experts reaching a 3x spread usually means they were given different information.

What does a court-admissible valuation report need?

A written conclusion of value from a credentialed appraiser, prepared under professional standards such as the AICPA's SSVS or the NACVA and ASA equivalents, stating the standard of value, the valuation date, the scope of work, the sources relied on, all three approaches with reasons for the weighting, and the appraiser's qualifications. Anything less invites a challenge to the expert.

The credential matters. ABV (Accredited in Business Valuation, held by CPAs), CVA (Certified Valuation Analyst), and ASA (Accredited Senior Appraiser) are the three family courts see most often. Ask about testimony experience in your state, not just the letters.

No automated tool, ours included, produces a court-admissible report, and we set out that distinction in detail in our comparison of a certified appraisal versus an estimate. The same is true of broker opinions of value, which are marketing documents rather than appraisals. If you need something signed, hire a person.

Can I use an online business valuation in a divorce?

Not as evidence, no. What a fast self-serve estimate is genuinely good for is sizing the number privately before you commit to a five-figure forensic engagement, so you walk into the first attorney meeting knowing whether you are arguing about $400,000 or $4M. That single fact changes your entire strategy and budget.

The practical sequence most owners should follow: run your normalized earnings through a business valuation estimator to get a range from three methods, see which drivers are carrying the value, and take that range to your attorney. If the business is a minor share of the marital estate, you may settle it with an agreed number and no expert at all. If it is the largest asset in the marriage, you now know the engagement is worth paying for, and you have a rough check on whatever the experts eventually produce. Use it as preparation, not proof, then hire the credentialed appraiser your case requires.
