If you own a business and you are getting divorced in Minnesota, the first question is whether your company counts as marital property. In most cases, a business you started or grew during the marriage is at least partly marital, which means its value gets divided between you and your spouse. You usually keep running the business and buy out your spouse’s share, rather than sell the company outright. To do any of that fairly, you first need to know what the business is worth.
I have practiced Minnesota family law for 26 years, much of it on high-conflict and business divorce cases. Below, I walk through how these cases actually work and the steps that protect a company before and during a divorce.
It depends on when and how you acquired it. Minnesota law defines marital and nonmarital property in Minn. Stat. 518.003, subdivision 3b. Property acquired by either spouse during the marriage is presumed marital. That presumption applies even if the business is titled in only one name.
A business you owned before the marriage is generally nonmarital. So is one you received by gift or inheritance. The complication is growth. If a business you owned before the marriage gained value during the marriage, that increase can become marital property. The same happens when you mix marital money or marital effort into a nonmarital company.
In practice, the cleanest “I owned it first” defense falls apart fast once marital funds, marital labor, or commingled accounts enter the picture. Your divorce lawyer will spend a lot of early case work trying to trace which dollars and which years are nonmarital, because that tracing often decides how much is on the table.
You cannot divide a business until you know its value. A valuation is usually done by a credentialed financial expert, called CBV or Certified Business Valuator. This expert reviews income statements, balance sheets, and cash flow, then weighs assets, liabilities, and the realistic potential for future earnings.
Timing matters too. Under Minn. Stat. 518.58, marital property is valued as of a specific valuation date, and the court divides it in a way that is equitable. Equitable means fair. It does not always mean a 50/50 split.
Most disputes I see are not about the math. They are about the assumptions behind the math, such as the growth rate, the owner’s salary, and how much the business depends on one person.
In Rochester and the rest of Olmsted County, a large share of the business divorces I handle involve a professional practice, a clinic, a consulting group, or a specialty firm tied to the region’s medical economy. Those cases turn on one question: how much of the value is personal goodwill that belongs to the working spouse, and how much is enterprise goodwill the business would keep if that person walked away. Minnesota treats those two very differently, and getting the line wrong can be a big issue.
You usually do not have to sell. The most common outcome is a buyout. One spouse keeps the company and compensates the other for their marital share, often by trading other assets like home equity or retirement funds. Often it comes as a payout over time with fixed terms.
Selling and splitting the proceeds is an option, but it is rarely the first choice when one spouse runs the business day to day. Continued joint ownership after divorce is also possible, though in my experience it works only for couples who can still cooperate closely. For most people, a clean buyout protects both the company and the relationship going forward.
The owners who come through divorce in the best shape are almost always the ones who prepared. A few steps make a real difference.
A well-drafted prenup or postnup can define the business as nonmarital and set how any growth is treated. This is the single most effective tool I see. It only works if it is done correctly and well before a divorce is on the horizon.
The cost of a prenup is surprisingly affordable and really can help if you end up getting divorced in the future.
Run the business through its own accounts. Pay yourself a reasonable salary. The more you blur personal and business money, the easier it is for the other spouse to claim a stake in the company itself. Clear separation narrows what is even arguable.
Sloppy books invite claims. When records are incomplete, the non-owner spouse gets room to argue that the business is worth more than it is, or that marital money built it. Organized financials let your valuation expert do clean work and shorten the fight.
For a business owner, a contested courtroom battle is often the worst outcome. Litigation is slow, public, and expensive, and the stress can spill into the company itself. A nasty dispute can damage the very asset both spouses are fighting over. Also, the non-business-owning spouse has the ability to try the “nuclear option.” That’s where everything is liquidated and sold. It’s best to avoid litigation, meaning a divorce trial, if at all possible.
That is why I push most business clients to seriously explore settlement first. Mediation and other forms of alternative dispute resolution let you keep control of the outcome. The Minnesota Judicial Branch recognizes mediation as an effective path in divorce cases. It is not the right fit for every situation, but for owners, it deserves a hard look.
High-income and high-net-worth divorces add another layer. When there are complex holdings, or when one spouse suspects the other is concealing income or assets, a forensic accountant can trace the money and value what is really there. I cover that process in more detail in my article on forensic accounting in a high-income Minnesota divorce.
