When a closely held business sits inside a marital estate, three decisions can move its value by six figures. Those decisions are the standard of value you apply, how the goodwill gets split, and the date you value as of. Get any one wrong and the record suffers. For a family-law attorney, the business is often the single largest, least liquid, and most contested asset on the table. It rarely trades, so there’s no ticker to point to. Worse, the wrong assumptions can quietly inflate or deflate the number before anyone challenges it. This guide walks you through what to demand from your valuator and what to send on day one. It also shows how Louisiana’s community-property rules change the math. In our 15 years valuing Gulf South businesses, we’ve found a clear pattern. The cases that hold up are the ones where counsel framed these issues early.

Key Takeaways
– The standard of value (fair market value vs. fair value) decides whether marketability and control discounts apply, which alone can swing the number materially (Porte Brown, 2023).
– Enterprise goodwill is generally divisible; personal goodwill often is not, but treatment varies sharply by state (Mercer Capital, 2023).
– Double-dipping counts the same income twice: once as a divisible asset, again as support.
– Louisiana is different. The community ends retroactive to filing (La. C.C. art. 159), but assets are valued at the partition trial (La. R.S. 9:2801).
– Engage a credentialed valuator early with the right documents to protect the record.
Is the business even a marital asset?
Classification comes before valuation, and it controls how much of the business is actually on the table. Most valuations run on willing-buyer, willing-seller logic (IRS Rev. Rul. 59-60). Under that logic, you first establish what the enterprise is worth. Then you ask how much of that value belongs to the marital or community estate. Those are two separate questions, and conflating them is a common early error.
The classification turns on when and how the business was acquired. It also turns on how value grew during the marriage. Here is a practical doctrine to flag. Courts often distinguish active appreciation from passive appreciation. Active appreciation is growth driven by an owner-spouse’s effort during the marriage, and it is generally marital. By contrast, passive appreciation is growth driven by outside market forces, and it is often treated as separate property (Porte Brown, “Divorce Valuations: Active Versus Passive Appreciation,” 2023). This varies by state, so confirm your jurisdiction’s rule.
In our experience, attorneys lose ground when they hand the valuator a business without telling them the marriage timeline. The valuator can’t apportion active versus passive growth they don’t know about. Send the formation date, the marriage date, and any capital-event history up front.
Citation capsule: Classification precedes valuation. Most valuations apply the willing-buyer, willing-seller standard of IRS Revenue Ruling 59-60, then apportion the result. Courts frequently separate active appreciation (owner effort during marriage, generally marital) from passive appreciation (market forces, often separate). Treatment varies by state (Porte Brown, 2023).
Standard of value: fair market value vs. fair value
The standard of value is the assumption that decides whether discounts apply, and it is the single most consequential choice in a divorce valuation. Fair value is the standard many states use in marital matters. It generally applies no marketability or minority-interest (control) discounts. Fair market value, by contrast, may apply both. That difference alone can move a minority-interest conclusion materially (Porte Brown, “What Is the Correct Standard of Value in Divorce,” 2023; REDW, “Marketability Discounts in Divorce,” 2023).
Standard of value varies by state. Most jurisdictions default to fair market value, while others apply a “fair value to the holder” concept that intentionally strips discounts to avoid undercompensating the non-owner spouse (Merrimack Business Appraisers, “State-by-State Standards of Value,” 2023). Louisiana practice leans toward fair market value, and I have seen it firsthand. In a May 2026 Orleans Parish divorce matter where I served as the valuation expert, every expert report, on both sides, used fair market value as the standard of value. That is not a guarantee for your case, because the standard can turn on the facts and the court, so confirm it with counsel early. The choice drives whether a marketability discount survives, which can move the conclusion by six figures.
Fair market value itself comes from a hypothetical willing buyer and willing seller. Neither is under compulsion, and both are reasonably informed (IRS Rev. Rul. 59-60). The doctrine is old. Even so, the discount question it raises is where divorce cases are won or lost.
Table 1: Fair Market Value vs. Fair Value
| Fair Market Value | Fair Value | |
|---|---|---|
| Marketability discount? | May apply | Generally not applied |
| Control / minority discount? | May apply | Generally not applied |
| Conceptual buyer | Hypothetical willing buyer | Often the holder, no forced sale |
| Typical use | Tax, gift, estate, many divorces | Statutory fair value; some divorce regimes |
Sources: IRS Rev. Rul. 59-60; Porte Brown (2023); REDW (2023). Application varies by state; confirm Louisiana’s standard with counsel.
Citation capsule: In a divorce, fair market value may apply marketability and control discounts, while fair value generally applies neither. That distinction can swing a minority-interest conclusion materially. The applicable standard varies by state, so the threshold question for any retaining attorney is which standard governs (Porte Brown, 2023; REDW, 2023).
The three approaches, and when each one fits
A credentialed valuator must consider all three approaches. The valuator must also justify any approach considered but not applied. Professional standards require this (AICPA SSVS No. 1, applied through NACVA, 2024). In practice, the appraiser evaluates the asset, income, and market approaches, then documents why one drives the conclusion. A report that silently ignores an approach is a report a competent cross-examiner can attack.
Each approach fits different facts. The income approach suits a profitable operating company with predictable earnings. The market approach suits a business with comparable transaction data. The asset approach suits holding companies, asset-heavy operations, or businesses where earnings don’t support going-concern value. Knowing which your valuator chose, and why, tells you how defensible the number is.
We’ve found that when a business is profitable as a going concern, both the income and market approaches are expected, and a report that leans on only one invites a challenge. The income approach is also where the double-dip and key-person issues live, so ask your valuator to walk you through every approach considered, not just the one that drove the conclusion. That conversation often surfaces the weak points before opposing counsel does.
Table 4: Three Approaches at a Glance
| Approach | Best when… | Watch for |
|---|---|---|
| Income | Stable, predictable earnings | Double-dip; owner-comp normalization |
| Market | Good comparable-sale data exists | Comparability of the guideline data |
| Asset | Holding/asset-heavy; weak earnings | Whether goodwill is captured |
Source: AICPA SSVS No. 1, via NACVA (2024).
Citation capsule: Professional valuation standards require an appraiser to consider the asset, income, and market approaches and to justify any approach considered but not applied (AICPA SSVS No. 1, via NACVA, 2024). For attorneys, a report that omits an approach without explanation is a reliability vulnerability worth probing in deposition.
Goodwill: personal vs. enterprise, and what’s divisible
Goodwill is where divorce valuations fracture, because not all of it divides. Personal goodwill is tied to the individual owner. It covers their relationships, reputation, and skill, none of which transfer in a sale. Enterprise goodwill, by contrast, belongs to the business itself. It covers brand, location, systems, and a trained workforce that survive the owner’s departure (Mercer Capital, “Personal vs. Enterprise Goodwill,” 2023).
The divisibility rule is jurisdiction-specific, and the variance is wide. Enterprise goodwill is generally treated as a divisible marital asset. Personal goodwill is often excluded, as it is in Louisiana. Still, states diverge: some exclude personal goodwill from the marital estate, while others include it (GMA CPA, “Valuing Goodwill in a Divorce,” 2024; Mercer Capital, 2023). Because the treatment varies by state, the personal-versus-enterprise split is one of the first things to confirm under your governing law before you let it drive a number.
One related concept is worth flagging: the key-person discount. This is a reduction in value a valuator may apply when a business depends heavily on one individual, reflecting the risk that the person leaves (Willamette Management Associates, 2017). In a divorce, that discount and the personal-goodwill question often point at the same underlying fact. Both ask how much of this value walks out the door with the owner-spouse.
Table 2: Personal vs. Enterprise Goodwill
| Personal Goodwill | Enterprise Goodwill | |
|---|---|---|
| Definition | Tied to the individual owner | Tied to the business entity |
| Examples | Personal relationships, reputation, skill | Brand, location, systems, trained staff |
| Generally divisible? | Often not (varies) | Generally yes |
| Varies by state? | Yes, sharply | Less so |
Sources: Mercer Capital (2023); GMA CPA (2024). Divisibility varies by state; confirm the rule with counsel.
Citation capsule: Personal goodwill is inseparable from the individual owner; enterprise goodwill is transferable with the business (Mercer Capital, 2023). Enterprise goodwill is generally a divisible marital asset, while personal goodwill is often excluded, though states diverge sharply on the treatment (GMA CPA, 2024). Confirm the rule in your jurisdiction.
Double-dipping: the same dollar counted twice
Double-dipping is the practice of counting one income stream twice, and it is the most overlooked trap in a divorce with a business. The same stream is first capitalized into the value of the business for property division. Then it is counted again as income to fund alimony or support (GMA CPA, “Double Dipping in Divorce,” 2024). As a result, the trap links the valuation directly to the support fight. Some states limit or bar it, while others permit it. This varies by state.
The mechanics matter for the attorney, not just the expert. Under the income approach, a valuator capitalizes the business’s earnings into a present value. Those earnings include the portion attributable to the owner. Suppose the court then divides that asset and separately treats the same earnings as the owner’s income for support. The owner-spouse now pays on the same dollar twice. Recognizing the overlap is how you protect or attack a number, depending on which side you sit.
Citation capsule: Double-dipping counts a single income stream twice: once capitalized into business value for property division, and again as income used to set alimony or support (GMA CPA, 2024). Some states limit the practice, others permit it, so the overlap between the valuation report and the support calculation is a point every retaining attorney should scrutinize.
The valuation date, and why Louisiana is different
The valuation date is the date as of which the business is appraised, and it can capture or exclude an entire run of appreciation. Louisiana sits on a genuine tension here that national pages miss. Here’s the nuance to flag. Under La. C.C. art. 159, the community property regime terminates retroactive to the date the divorce petition is filed (Justia, La. Civil Code art. 159). However, under La. R.S. 9:2801, community assets are valued as of the partition trial (Justia, La. R.S. 9:2801). In short, the regime ends at filing, but the value is set at trial.
That gap matters because of what happens to the business in between. Suppose a business grows after filing but before the partition trial. The date you argue then determines whether that appreciation gets captured or excluded. It also determines whether the growth is characterized as community or separate. Crucially, the active-versus-passive appreciation question reappears here. Post-filing growth driven by owner effort raises different issues than growth driven by the market. This is a Louisiana-specific interplay. Confirm the current statutes and case law with counsel, because the date you build your record around drives the result.
In Gulf South matters, we’ve found this date tension is the most frequently misunderstood Louisiana wrinkle. Attorneys who lock in the valuation-date theory early, and instruct the valuator accordingly, avoid a scramble when the business’s interim performance changes the picture.
Citation capsule: In Louisiana, the community property regime terminates retroactive to the divorce petition filing (La. C.C. art. 159), yet community assets are valued as of the partition trial (La. R.S. 9:2801). That gap determines whether post-filing business appreciation is captured. This Louisiana-specific interplay should be confirmed with counsel against current statutes and case law.
What to send your valuator on day one
A valuation moves only as fast as the documents, so the fastest cases start with a complete day-one package. Professional standards require the valuator to consider all three approaches (AICPA SSVS No. 1, via NACVA, 2024). Because each approach is hungry for source data, the gaps show up fast. Sending a clean, complete set up front prevents the back-and-forth that stalls engagements and weakens the eventual report.
Here is the core engagement checklist we ask retaining attorneys to assemble:
- Three years of business tax returns plus year-to-date financial statements.
- Owner compensation detail, including perks, benefits, and any above- or below-market pay (needed to normalize earnings).
- Related-party and lease agreements, especially owner-owned real estate rented to the business.
- Any buy-sell agreement or operating/partnership agreement with transfer or valuation provisions.
- Customer concentration data: revenue by top customers, to gauge key-person and concentration risk.
- The marriage and formation timeline, plus any capital events, so the valuator can apportion active versus passive appreciation.
Across our Gulf South valuation engagements, the single biggest delay isn’t analysis, it’s missing owner-compensation detail and related-party leases. When those arrive on day one, the recast and the conclusion move dramatically faster. Build them into your retention letter as deliverables from the client.
Before you retain, ask three questions: Which standard of value will you apply, and why? How will you treat personal versus enterprise goodwill? What’s your position on the valuation date for this jurisdiction? The answers tell you whether the expert understands the case.
Citation capsule: A complete day-one package, three years of returns, owner-compensation detail, related-party leases, buy-sell agreements, customer-concentration data, and the marriage timeline, lets a valuator apply all three approaches required by professional standards (AICPA SSVS No. 1, via NACVA, 2024). Incomplete data is the most common cause of delay and a weaker, more challengeable report.
Vetting the expert: neutral vs. retained, and Daubert
Your choice of expert and your choice of engagement structure both shape how the report holds up under challenge. A jointly-retained neutral expert can reduce conflict, cost, and delay compared to dueling party experts. By contrast, a party-retained expert offers an advocate within the bounds of professional standards (Central Pacific Valuation, “Jointly-Retained Valuation Experts,” 2026). Neither is universally right. The cost-versus-credibility tradeoff depends on the matter.
Admissibility is the other half of vetting. The Daubert standard is the rule under which a court screens expert testimony for reliability. Under Daubert and Kumho Tire, the court acts as that gatekeeper. Federal Rule of Evidence 702 was amended in December 2023 to sharpen that gatekeeping (Cornell Legal Information Institute, “Daubert Standard”). So here is the practical question for you. Will this report survive a reliability challenge? A credentialed valuator who documents methodology, justifies the rejected approaches, and ties conclusions to recognized standards gives you a report built to withstand that scrutiny.
A recent engagement shows why this matters. A CPA brought us in to value a business the owner said he wanted to sell. As we worked, it became clear the two partners had already entered litigation, and the valuation was really meant to help settle the dispute between them. Because we work to NACVA professional standards, we caught the shift, reframed the assignment as a neutral engagement paid for by the company, and wrote a report built to stand up under Daubert. Most business brokers and M&A advisors do not have the technical expertise to produce that kind of report. If litigation is even possible, let alone already underway, paying for a valuation that does not meet professional standards is wasted money.
When you engage Duran Advisors, you get credentialed business valuation grounded in 15 years of Gulf South experience. The work is doctrine-sourced and neutral, with no outcome promises. If you’d like to talk through engaging a valuator for a specific matter, we offer a confidential consultation. Schedule a confidential consultation.
Citation capsule: A jointly-retained neutral expert can lower conflict, cost, and delay versus competing party experts (Central Pacific Valuation, 2026). Admissibility runs through Daubert and Kumho Tire reliability factors, with Federal Rule of Evidence 702 amended in December 2023 to tighten judicial gatekeeping (Cornell LII). A documented, standards-based report is built to survive that challenge.
Frequently Asked Questions
How is a business valued in a divorce?
A credentialed valuator considers three approaches: asset, income, and market. The valuator then justifies the one that drives the conclusion (AICPA SSVS No. 1, via NACVA, 2024). First, the valuator establishes the standard of value. Next, the valuator normalizes earnings, accounts for goodwill, and applies any appropriate discounts. The marital or community share is then apportioned. Treatment varies by state.
What is double dipping in a divorce business valuation?
Double-dipping counts the same income stream twice: once capitalized into the business’s value for property division, and again as income used to set alimony or support (GMA CPA, 2024). Some states limit or bar the practice; others permit it. This varies by state, so check your jurisdiction’s rule and watch where the valuation report and the support calculation overlap.
Fair market value vs. fair value in divorce, what’s the difference?
Fair market value may apply marketability and control discounts; fair value generally applies neither (Porte Brown, 2023; REDW, 2023). That distinction can swing a minority-interest conclusion materially. The standard that governs varies by state, so the first question to settle in any matter is which standard your jurisdiction requires for marital property.
Is my spouse’s business marital property?
It depends on classification, which precedes valuation. Courts often treat active appreciation from an owner’s effort during the marriage as marital. By contrast, they often treat passive appreciation from market forces as separate (Porte Brown, 2023). This varies by state. In Louisiana, the community regime terminates retroactive to the petition filing (La. C.C. art. 159), so the timeline matters. Confirm the rule with counsel.
What is the valuation date for a business in a Louisiana divorce?
Louisiana sets up a tension. The community regime ends retroactive to the divorce petition filing (La. C.C. art. 159, Justia), but community assets are valued as of the partition trial (La. R.S. 9:2801, Justia). Post-filing appreciation can therefore be captured or excluded depending on the date theory. This is Louisiana-specific; confirm current statutes and case law with counsel.
Conclusion
Three decisions drive a divorce business valuation: the standard of value, the goodwill split, and the valuation date. In Louisiana, the date also carries a unique filing-versus-trial tension. So engage a credentialed valuator early, and send a complete day-one package. Before you retain, confirm the expert’s positions on standard, goodwill, and date. Done right, you get a documented, standards-based report built to survive a reliability challenge. To talk through engaging a valuator for a specific matter, schedule a confidential consultation.
