Divorce Business Valuation for a Sole Proprietorship in 2026

A sole proprietorship in a divorce is the hardest small-business valuation there is, because the business and the owner are legally the same thing. There’s no entity, no shares, no clean line between “the company” and “the person.” That makes the goodwill question, how much of the value is the owner (personal, often not divisible) versus how much is the business (enterprise, divisible), the central fight. And it makes the standard of value, which varies by state, decisive. This guide explains how a sole proprietorship gets valued in a divorce, the goodwill split, the double-dipping trap, and what a family-law-experienced appraiser actually does.

We’re CT Acquisitions, a buy-side M&A advisory firm, not a credentialed appraisal or family-law firm; for a divorce valuation you need a credentialed appraiser (and your divorce attorney). This page is general orientation, not legal advice.

How a sole proprietorship gets valued in a divorce

The starting mechanics are the same as any small owner-operated business, the market (multiple) approach: take normalized Seller’s Discretionary Earnings (SDE), reported profit plus the owner’s compensation and benefits, plus personal expenses run through the business, plus one-time items, and multiply by a market multiple for the industry and size. An appraiser may also run a discounted cash flow (income approach) or, for an asset-heavy proprietorship, an adjusted-net-asset (asset approach) calculation, and reconcile to a range. So far, ordinary. What’s different in divorce, and especially for a sole proprietorship, is everything that happens next.

The central issue: personal vs. enterprise goodwill

Most of a small service business’s value above its tangible assets is goodwill. Family courts in many states split goodwill in two:

For a sole proprietorship, this split is decisive. There’s no entity, no shares, no management layer, the business often is the owner’s individual practice. Indicators that point toward personal goodwill: the owner personally performs the core work, customers come for the owner specifically, there’s no transferable workforce or systems, and a sale would realistically require a long non-compete and earnout because the buyer is really buying the owner’s continued involvement. The more the value is personal goodwill, the smaller the divisible marital asset, sometimes dramatically so. (Note: state law varies, a minority of states include all goodwill, and the analysis can also turn on whether a non-compete is in play.)

The standard of value, and why your state matters

“Value” isn’t one thing. Divorce courts apply a standard of value that varies by state and changes the number:

• Fair market value, the price between a hypothetical willing buyer and seller; often applies discounts for lack of control and lack of marketability, and excludes synergies. Common in many states.
• Fair value, a statutory standard used in some states, which may not apply marketability/minority discounts, producing a higher number.
• Investment value, value to a specific owner, used in some jurisdictions, which can include the value the business has specifically to the spouse running it.

On top of that: states differ on the goodwill treatment, on whether the business is valued as of the date of separation or the date of trial, and on community-property vs. equitable-distribution rules for how a marital asset is split. Two appraisers in two states valuing the same proprietorship can land far apart, legitimately, because the legal framework is different. This is why a family-law-experienced appraiser and a divorce attorney in your state are not optional.

The double-dipping trap

“Double-dipping” (or “double counting”) is when the same dollar of income gets used twice: once to value the business as a divisible asset (because the valuation capitalizes that income stream), and again as income available for spousal/child support. Many courts limit this, for example, by valuing the business excluding the owner’s reasonable compensation (which then funds support) so the asset and the support stream aren’t built on the same money, but the rules and remedies vary by jurisdiction. It’s a frequent point of dispute, and a competent appraiser and attorney will structure the analysis to address it.

What the appraiser does (and what you should provide)

• Determines the standard of value and valuation date applicable in your state for divorce.
• Normalizes earnings, owner compensation, personal expenses, one-time items, family on payroll, below-market rent in owner-owned property, to a clean SDE/EBITDA.
• Selects and applies methods (market multiple, possibly DCF, possibly asset), using comparable data, and reconciles to a range.
• Allocates value between enterprise and personal goodwill, using factors like owner-performed work, customer attachment to the owner, transferability of staff and systems, and what a real sale would require.
• Applies appropriate discounts (lack of control, lack of marketability) consistent with the state’s standard.
• Addresses double-dipping in coordination with the support analysis.
• Produces a formal report and, if needed, testifies.

You (or your attorney) should provide: 3-5 years of tax returns and financials, bank statements, the books, customer/contract information, equipment and asset lists, leases, any prior valuations, and an honest picture of how dependent the business is on you personally, that last point drives the goodwill allocation more than anything.

Common ways the number gets distorted (in both directions)

• Inflated add-backs by the owner-spouse to lower the valuation (or the reverse, by the other side to raise it).
• Sandbagging the business, the owner-spouse suddenly “can’t” generate the historical income; appraisers normalize to sustainable levels and look for manipulation.
• Ignoring the goodwill split, treating all goodwill as divisible when state law would exclude personal goodwill, or vice versa.
• Wrong standard of value, applying fair market value where the state uses fair value (or the reverse), which can swing the number significantly via the discounts.
• Double-dipping, capitalizing the owner’s full compensation into the asset value and then also counting it for support.
• Stale or selective data, valuing as of the wrong date, or cherry-picking a good or bad year.

Bottom line and where we fit

A sole proprietorship in a divorce is valued like any small owner-operated business, normalized SDE times a market multiple, but the answer turns on legal questions, the standard of value in your state, the personal-versus-enterprise goodwill split, the valuation date, and the double-dipping rules, far more than on the arithmetic. Get a credentialed appraiser (ASA, ABV, or CVA) experienced in family-law valuation and a divorce attorney in your state; a broker estimate or an online tool won’t serve here. We’re not that appraiser, we’re a buy-side M&A firm, so we’ll point you to one. If a sale of the business ever becomes part of the picture (some divorcing owners do sell), our free valuation tool gives a market check, our business valuation disputes and valuation resources pages explain the methodology, and our broker alternative guide explains the buyer-paid model.

Frequently asked questions

How is a sole proprietorship valued in a divorce?

Typically with the market approach: normalized Seller’s Discretionary Earnings (SDE), reported profit plus the owner’s compensation and personal expenses plus one-time items, multiplied by an industry/size multiple, sometimes cross-checked with a discounted cash flow or an adjusted-net-asset calculation. The harder part is legal: the court applies a state-specific standard of value, decides how to treat goodwill (often excluding ‘personal goodwill’ tied to the owner), picks a valuation date, and guards against ‘double-dipping.’ A credentialed appraiser experienced in family-law valuation handles all of that.

What is the difference between personal goodwill and enterprise goodwill in a divorce?

Enterprise (business) goodwill is value that would transfer to a buyer, brand, location, systems, recurring contracts, trained staff, repeat customers not attached to the owner personally, and it’s generally included in the marital estate and divisible. Personal (professional) goodwill is value tied to the owner as an individual, their skill, reputation, relationships, and ongoing efforts, that a buyer couldn’t acquire; many states exclude it from the marital estate. For a sole proprietorship, where the business often is the owner’s individual practice, a large share of the value can be personal goodwill, which reduces the divisible amount.

Does my spouse get half of my sole proprietorship in a divorce?

Not necessarily half, and not necessarily of the whole value. First, only the marital portion is divisible, and in many states personal goodwill (value tied to you individually) is excluded, which can be a large fraction of a sole proprietorship’s value. Second, the split depends on whether your state is community-property (often a 50/50 starting point) or equitable-distribution (a ‘fair’ split that may not be 50/50, weighing many factors). The actual outcome depends on the goodwill allocation, the standard of value, and your state’s distribution rules, this is exactly why a family-law attorney and a credentialed appraiser are essential.

What is double-dipping in a divorce business valuation?

Double-dipping (or double counting) is when the same income is used twice: once to value the business as a divisible asset (because the valuation capitalizes that income stream) and again as income available for spousal or child support. Many courts limit it, often by valuing the business excluding the owner’s reasonable compensation, so the asset value and the support obligation aren’t built on the same dollars, but the rules vary by state. A competent appraiser and attorney structure the analysis to address it; ignoring it can substantially overstate what the non-owner spouse receives.

What standard of value is used in a divorce business valuation?

It varies by state. Many states use fair market value (the price between a hypothetical willing buyer and seller, often with discounts for lack of control and marketability and no synergies). Some use fair value (a statutory standard that may not apply those discounts, producing a higher number). Some use investment value (the value to the specific spouse who owns it). The choice materially affects the result, mainly through whether marketability and minority discounts apply, so you need an appraiser who knows your state’s standard.

Do I need a certified appraiser for a divorce business valuation?

Yes. A divorce business valuation has to withstand scrutiny from opposing counsel and a judge, often with each side presenting its own expert, so you need a credentialed appraiser (ASA, ABV, or CVA) experienced specifically in family-law valuation, not a business broker’s free opinion or an online estimate, neither of which carries professional standing or addresses the goodwill split, the standard of value, and the double-dipping issues that drive the outcome. Your divorce attorney will typically recommend appraisers they’ve worked with.

How is goodwill calculated for a sole proprietorship in a divorce?

There’s no single formula; the appraiser determines total business value (usually normalized SDE times a market multiple), subtracts the value of tangible net assets, and treats the remainder as goodwill, then allocates that goodwill between enterprise and personal components using factors such as: how much of the core work the owner personally performs, whether customers come for the owner specifically, whether there’s a transferable workforce and documented systems, the owner’s age and reputation, and what a realistic sale would require (a long non-compete and earnout signal heavy personal goodwill). The allocation is judgment-based and frequently the most contested part of the valuation.

Can my spouse force me to sell my sole proprietorship in a divorce?

Usually not, courts generally prefer to award the business to the owner-spouse and ‘offset’ the other spouse with other marital assets or a structured payment, because forcing a sale of an owner-dependent business often destroys much of its value (and the income both parties may rely on). A sale is more likely only if there aren’t enough other assets to offset, the parties agree to it, or the business genuinely can’t be divided otherwise. If a sale does happen, that’s a separate process, and a market-based valuation (such as our free tool provides) and a competitive sale process become relevant.
