Can My Spouse Claim Ownership of My Business in a Divorce?

by | Jun 23, 2026 | Family Law |

For many business owners, the business isn’t just another asset in a divorce. It’s years of long hours, financial risk, missed weekends, and difficult decisions. It’s the livelihood you’ve built from the ground up, and you’re desperate to protect it. So when divorce becomes a reality, one question often rises above all the others:

Can my spouse take part of my business?

The answer is: possibly. Under Michigan’s equitable distribution laws, a spouse may have a claim to some portion of a business, but the outcome depends on factors such as:

  • When and how you acquired the business.
  • If the business’s value grew during the marriage.
  • If your spouse contributed, actively or passively, to the business’s growth.
  • How much you are willing to negotiate and reach other favorable terms.
  • The strength of your legal representation.

Since 1982, the Law Offices of Michael A. Robbins has represented business owners, professionals, and high-net-worth individuals facing complex divorce matters throughout Michigan. We’re ready to help you better understand how courts treat business ownership so you know what to expect and what options are available.

How Do Courts Determine Whether My Business Is Marital Property?

Michigan law follows an equitable distribution model for dividing assets in a divorce. Under this model, courts separate property into two categories: marital property and separate property. Marital property is jointly owned and must be divided fairly between spouses, while separate property is typically not subject to division. However, the line between these two categories can become blurred, especially when a business is involved.

When deciding how to classify a business, courts look at its origin and what happened to it during the marriage. Three common scenarios arise:

  •  Business Started Before Marriage: The original value at the time of marriage may be considered separate property. However, any increase in value that occurred during the marriage could be subject to division.
  •  Business Started During the Marriage: If you founded the company after you married, courts will likely treat the business as a marital asset, regardless of whose name is on the ownership documents.
  •  Spouse Contributed to the Business: If your spouse worked in the company, managed its finances, or made sacrifices that allowed you to grow it, those contributions can support a claim to a share of its value.

Determining whether a business or its growth is marital property is the first step. The next step is figuring out what it is worth so it can be divided fairly.

How Is a Business Valued During a Divorce?

Valuation is one of the most consequential issues in any business divorce case. Without an accurate figure, neither party can negotiate effectively, and courts cannot divide the estate fairly.

Three common approaches are used:

  • Income-Based Approach: Values the business based on its expected future earnings, often using capitalization of earnings or discounted cash flow methods.
  • Asset-Based Approach: Calculates value based on the net value of the business’s assets minus its liabilities.
  • Market-Based Approach: Compares the business to similar companies that have recently sold.

Each method produces different results, and both spouses often hire their own valuation experts, which can lead to disagreements. An attorney with experience in business divorce cases knows how to challenge inflated valuations and advocate for an accurate assessment.

Why Does It Matter Whether Business Growth Was Active or Passive?

The source of a business’s increased value can significantly affect how much, if any, of that growth is divisible in divorce.

  • Active Growth: Refers to increases in value resulting from the owner’s direct efforts: management decisions, acquiring new clients, expanding operations, or improving profitability through hard work and skill.
  • Passive Growth: Refers to increases driven by external forces: favorable market conditions, economic trends, or appreciation unrelated to anyone’s personal effort.

Michigan courts often examine the source of growth carefully. Active appreciation driven by your own efforts during the marriage is more likely to be treated as a marital asset than passive appreciation driven by market conditions alone. This distinction can make a meaningful difference in the final outcome.

If My Spouse Has a Claim, Will I Have to Give Up the Business?

Almost certainly not. Courts generally avoid forcing a business to be sold or requiring co-ownership between divorcing spouses. Keeping the business running is usually in everyone’s interest.

Common options for retaining ownership include:

  • Cash Buyout: You pay your spouse a lump sum equal to their share of the business value.
  • Installment Payments: You pay out your spouse’s interest over time, which can make a buyout financially manageable.
  • Asset Offset: You keep the business, and your spouse receives other marital assets of comparable value, such as real estate or investment accounts.

The right approach depends on the business’s valuation, the couple’s overall asset picture, and what both parties are willing to accept. With proper planning and skilled negotiation, retaining full ownership is achievable in many cases.

How Can an Attorney Help Protect Your Business During Divorce?

Getting legal guidance early makes a significant difference. Here’s what an experienced attorney brings to the table:

  • Assessing What’s at Risk: An attorney identifies which portions of the business may qualify as marital property before the other side makes claims.
  • Coordinating with Valuation Experts: An attorney works with financial professionals to establish a defensible, accurate business value.
  • Building a Negotiation Strategy: An attorney structures a resolution that prioritizes your ownership while addressing your spouse’s legitimate claims.
  • Representing You in Litigation If Necessary: When negotiations break down, an attorney with courtroom experience protects your position.

The earlier you involve an attorney, the more options you have.

Keep Control of What You’ve Built

A spouse may have a claim to some portion of your business’s value under certain circumstances. However, that does not mean you’ll lose control of what you’ve built. Understanding how courts assess ownership, how valuation works, and what buyout options exist puts you in a far stronger position to reach a resolution that protects your livelihood.
