Business Valuation in a Wisconsin Divorce

Business valuation is the process of determining what a closely held business is worth so it can be accounted for in a divorce. In Wisconsin, a business built or grown during the marriage is marital property, and because the state presumes marital property is divided equally under Wis. Stat. § 767.61, the value assigned to that business directly shapes the entire settlement.^[1]

It is also one of the hardest numbers in any divorce to pin down. A business is not a bank account with a balance; its worth depends on assumptions about earnings, assets, market conditions, and goodwill that reasonable experts can read very differently. That is why business valuation so often becomes the central battleground in a divorce involving an owner.

Why the Business Is Part of the Divorce at All

Many owners are surprised the business is even on the table, especially if their spouse never worked in it. But Wisconsin's community property framework casts a wide net.

Under Wis. Stat. § 767.61, property acquired during the marriage is presumed marital and divided equally, and a business or the value created in it during the marriage is treated as part of the marital estate. It generally does not matter whose name is on the business or that only one spouse ran it. Retained earnings and the appreciation built by marital effort are themselves marital assets.^[2] Only a business owned before the marriage and kept genuinely separate, or received by gift or inheritance and never commingled, may fall outside the estate, and even then, growth during the marriage can be divisible.

How Experts Value a Business

Valuation experts generally rely on one or a combination of three recognized approaches. Which fits depends on the type of business, and a good expert explains why they chose the one they did.

• The income approach. Values the business on its ability to generate future earnings or cash flow, common for profitable operating businesses.
• The market approach. Compares the business to similar companies that have actually sold, where good comparables exist.
• The asset approach. Adjusts book value to the fair market value of the business's tangible and intangible assets, often used for asset-heavy or holding companies.

The valuation standard is fair market value, not book value or a tax figure. A number that does not reflect a genuine arm's-length transaction is not fair market value.^[3] A crucial part of the work is normalizing the owner's compensation and perks to show the real cash flow a buyer would actually see. 

Goodwill: Where Wisconsin Is Different

Goodwill, the intangible value of a business's reputation, client relationships, and earning power beyond its hard assets, is often the largest and most contested piece of a valuation. And Wisconsin treats it differently from many other states.

Many states split goodwill into enterprise goodwill (which belongs to the business) and personal goodwill (tied to the individual owner), and exclude personal goodwill from the marital estate. Wisconsin does not draw that line the same way. In McReath v. McReath, the Wisconsin Supreme Court held that all salable goodwill in a professional practice, whether it is characterized as enterprise or personal, is divisible marital property, as long as it is transferable, for example through a non-compete agreement.^[4] Only “pure” personal goodwill that cannot be sold or transferred stays out of the estate. For owners of practices and professional businesses, this is a significant point: more of the goodwill is divisible in Wisconsin than they may expect. 

What Makes a Business Hard to Value

Some businesses are far harder to value than others, and those are exactly the ones that spark valuation fights. A few features tend to complicate the number.

• Owner-dependent income. When the business's earnings depend heavily on the owner, separating business value from personal earning power is difficult.
• Cash-heavy operations. Businesses with significant cash income require careful documentation to establish true revenue.
• Irregular or growing earnings. Fast-changing income makes projecting future cash flow, and therefore value, contestable.
• Owner compensation and perks. Salaries, benefits, and personal expenses run through the business have to be normalized to show real profitability.

Because an owner's income and the business's value are intertwined, sorting out what income counts when a spouse owns a business is often part of the same analysis.

When Two Experts Reach Two Numbers

It is normal for each spouse's expert to arrive at a different value, sometimes dramatically different. That does not mean anyone is being dishonest; it usually reflects different, defensible assumptions.

Wisconsin judges have broad discretion to accept one valuation, reject another, or settle on a figure in between, and because a trial court's valuation of a closely held business is reviewed only for clear error, the number the judge chooses is very hard to overturn. This makes the credibility of your expert, and how well their methodology holds up under cross-examination, often more decisive than the raw figure. A well-supported valuation persuades; a weakly reasoned one gets discounted.

The Double-Dip Problem

There is a subtle but important wrinkle when a business is both divided as property and used to set maintenance. It is often called the double dip.

The concern is that the same business earnings get counted twice: once when the business's income-based value is divided as property, and again when that income is used to award maintenance. Wisconsin courts are aware of the issue, and in McReath the Supreme Court addressed how goodwill value and maintenance interact. It is a technical area, and how it is handled can meaningfully change the outcome for a business-owning spouse, which is why it deserves careful attention rather than being left to chance.

We help select a qualified valuation expert, coordinate the financial records they need, and prepare their analysis to withstand cross-examination. Where the other side's expert produces an inflated or deflated number, we know how to test the assumptions behind it, on goodwill, normalization, and the double dip, and show the court where it does not hold up.

Instead of billing by the hour while a valuation fight unfolds, we set a fixed fee for our representation at the start. You know the cost of our work before you hire us, and you can call with questions without watching a clock. The valuation expert's own fee is separate, and we are upfront about that too, so there are no surprises.

Common Business Valuation Mistakes

A handful of errors can badly distort what a business-owning divorce produces. Knowing them helps protect your share, on either side.

Relying on Tax Returns or Book Value

A business's reported numbers usually understate its true worth. Treating a tax return or balance sheet as the value can leave significant marital value unaccounted for.

Ignoring Goodwill

Given Wisconsin's broad treatment of salable goodwill, overlooking it, or wrongly assuming personal goodwill is excluded, can dramatically misstate the value.

Using an Unqualified Expert

A valuation is only as strong as the expert defending it. An underqualified appraiser whose method falls apart under questioning can sink a good position.

Overlooking the Double Dip

Failing to address how business value and maintenance interact can result in the same income being counted twice against an owner.
