If you or your spouse own a business and you are divorcing in Michigan, the business is likely subject to equitable division — even if only one spouse's name is on it. Michigan courts look at when the business was started or acquired, how much it grew during the marriage, and whether that growth was due to one spouse's active efforts. Valuation typically requires a forensic accountant or business appraiser, and the methods used — income, market, or asset-based — can produce significantly different numbers. According to Martindale-Nolo, contested divorces involving complex assets routinely cost $15,000 to $100,000 or more in total.
Oakland County has one of the highest concentrations of privately held businesses and professional practices in Michigan. When a business owner divorces, the business is usually the largest and most complex asset on the table. How it is valued and divided can determine whether the company survives the divorce intact.
This article explains how Michigan courts treat businesses in divorce — from classification as marital or separate property to the valuation methods that determine what the business is worth, to the practical options for resolution that allow you to keep operating.
When Is a Business Marital Property?
Michigan is an equitable distribution state under MCL 552.19. The first question in any business division case is whether the business — or any portion of it — qualifies as marital property.
Started during the marriage. If you started the business after the date of marriage, it is presumptively marital property. Both spouses contributed to the marriage during the period the business was built, and both are entitled to share in its value.
Started before the marriage. If the business existed before the marriage, its pre-marital value is generally classified as separate property. However, any increase in value during the marriage is potentially marital — particularly if that growth was driven by one spouse's active effort rather than passive market forces.
Commingling. Using marital funds to invest in the business, paying personal expenses from business accounts, or putting a spouse on the payroll can blur the line between separate and marital property. Once business and personal finances are commingled, tracing becomes necessary — and the burden of proving that an asset is separate falls on the spouse making that claim.
Inherited or gifted businesses. A business received as a gift or inheritance is generally separate property. But if the receiving spouse actively managed and grew the business during the marriage, the growth may be marital. And if marital funds were used to operate or expand the business, the separate property characterization weakens.
Three Valuation Methods
Business valuation in divorce is not a simple calculation. The number depends on who is doing the valuation, which method they use, and what assumptions they make. Understanding the three standard approaches is essential.
The Income Approach
The income approach values a business based on its ability to generate future income. The two most common methods are:
- Discounted cash flow (DCF): Projects future cash flows and discounts them to present value using a rate that reflects the risk of the business. More commonly used for growing businesses with predictable revenue.
- Capitalization of earnings: Takes a normalized earnings figure and divides it by a capitalization rate. More commonly used for stable, mature businesses with consistent earnings.
The income approach is often the most relevant for profitable operating businesses. It also tends to produce the highest valuations, which matters depending on which side of the table you are sitting on.
The Market Approach
The market approach values the business by comparing it to similar businesses that have recently sold. It uses databases of private business transactions and public company comparables to derive valuation multiples — typically a multiple of revenue, EBITDA, or seller's discretionary earnings.
The market approach works best when there are truly comparable transactions available. For highly specialized or niche businesses, finding good comparables can be difficult.
The Asset Approach
The asset approach values the business based on the fair market value of its assets minus its liabilities. It is most appropriate for asset-heavy businesses — real estate holding companies, equipment-intensive operations, or businesses being valued for liquidation purposes.
For service-based professional practices where the primary asset is the owner's expertise, the asset approach tends to understate value significantly.
Why the Method Matters
Each approach can produce a materially different number for the same business. In a contested divorce, each side typically retains its own appraiser — and each appraiser may select the method most favorable to their client's position. Understanding what drives the differences is critical to evaluating settlement offers and preparing for trial.
Active vs. Passive Appreciation
The distinction between active and passive appreciation often determines how much of a pre-marital business is subject to division.
Active appreciation results from a spouse's direct efforts — managing day-to-day operations, building client relationships, hiring and training staff, developing new product lines, expanding into new markets. When one spouse actively grows a business during the marriage, the growth is marital property regardless of when the business was founded.
Passive appreciation results from external factors — rising real estate values, favorable market conditions, industry-wide growth, inflation. Passive growth of a separate asset generally remains separate property.
The challenge is that most businesses experience both. A restaurant owner who opened before the marriage and expanded to three locations during the marriage has both passive appreciation (the general growth of the restaurant industry) and active appreciation (the expansion, management, and marketing that drove the specific growth). Separating the two requires expert analysis.
Enterprise Goodwill vs. Personal Goodwill
For professional practices and closely held businesses, the distinction between enterprise goodwill and personal goodwill is often the most consequential issue in the valuation.
Enterprise goodwill belongs to the business. It includes the value of the business's brand, location, trained staff, systems, processes, and institutional client relationships. Enterprise goodwill would transfer if the business were sold to a new owner. It is marital property subject to division.
Personal goodwill is tied to the individual. It includes the professional's personal reputation, individual client relationships that would not transfer, and the referral network built on personal connections. Personal goodwill is more difficult to divide because it cannot exist apart from the individual.
This distinction matters enormously for physicians, attorneys, financial advisors, consultants, and other professionals whose practices depend heavily on their personal reputation. A medical practice with strong enterprise goodwill (an established name, a desirable location, a trained medical staff) may have significant transferable value. A solo consultant whose clients follow them personally has less enterprise goodwill and more personal goodwill.
The appraiser's treatment of this issue can swing the valuation by hundreds of thousands of dollars.
Protecting Business Operations During Divorce
A contested divorce can disrupt business operations in ways that destroy value for both spouses. Michigan courts have tools to prevent this, and business owners should use them proactively.
Statutory restraining orders. Under MCR 3.207, when a divorce is filed, both parties are automatically restrained from dissipating marital assets. This prevents either spouse from draining business accounts, making unusual distributions, or transferring assets outside the normal course of business.
Maintaining the status quo. Courts expect businesses to continue operating normally during the divorce. Unusual compensation changes — dramatically increasing or decreasing the owner's salary, accelerating or deferring bonuses, making extraordinary capital expenditures — will be scrutinized. Maintain normal business practices and document everything.
Documenting business vs. personal expenses. During a divorce, every dollar that flows between the business and the owner's personal finances will be examined. Clean separation of business and personal expenses, supported by contemporaneous records, prevents allegations of dissipation or hidden income.
Protecting confidential business information. Business owners may seek protective orders limiting the other spouse's access to trade secrets, client lists, or proprietary financial information. Courts can restrict how business records obtained in discovery are used and who can see them.
Options for Resolution
The business does not have to be sold. In most cases, the operating spouse keeps the business and the other spouse receives offsetting assets. The question is how to structure the offset fairly.
Buyout with existing assets. The most common approach. The operating spouse keeps the business and the other spouse receives a larger share of other marital assets — the family home, retirement accounts, investment portfolios, or other real property. This works when there are sufficient non-business assets to offset the value.
Structured buyout payments. When the marital estate does not have enough liquid assets for a clean offset, the operating spouse may pay the other spouse's share over time — typically with interest and secured by business assets or other collateral.
Co-ownership. Rare and generally inadvisable. Divorcing spouses who continue to co-own a business face ongoing conflict, decision-making paralysis, and valuation disputes at the eventual sale. Courts rarely impose this arrangement.
Sale of the business. When neither spouse can afford to buy out the other and no offset is possible, a sale may be necessary. This is typically the least desirable outcome — forced sales under time pressure rarely achieve fair market value.
QDRO and retirement offsets. Retirement accounts are frequently used to offset business value. A Qualified Domestic Relations Order (QDRO) can transfer a portion of one spouse's retirement plan to the other without tax penalties, making it an efficient tool for balancing the division.
The Bottom Line
Dividing a business in a Michigan divorce requires accurate valuation, clear classification of marital and separate interests, and a resolution structure that works for both the business and the family. The decisions made during this process — from the choice of appraiser to the negotiation strategy — have lasting financial consequences.
If you own a business and are considering divorce in Oakland County or Southeast Michigan, the time to plan your approach is before the case is filed, not after. A strategy that accounts for valuation, operations, and tax implications from the outset protects both the business and your interests.
