Can My Spouse Claim Part of a Business I Started During Our Marriage?

 Posted on August 25, 2026 in Property Division

Your spouse may have a claim to part of a business you started during your marriage in Wisconsin. In a divorce, most property owned by either spouse is subject to division, even if only one spouse's name is attached to the business. This means a business you built and operated yourself may still be included in the property division process.

If you're worried about protecting your business in 2026, our Madison, WI divorce lawyer can help you understand your options.

Why Can Your Spouse Have a Claim to Your Business in a WI Divorce?

Under Wisconsin Statute Section 767.61, most property owned by either spouse is subject to division in a divorce. The court generally starts with a presumption that divisible property should be divided equally. However, it can order a different division after considering factors listed in the law.

Because of this, a business you started during your marriage will generally be part of the property considered during your divorce. This can be true even if the business is only in your name or your spouse never worked there. A spouse does not have to work directly in a family business for their contributions to the marriage to matter.

What Happens During Divorce if You Started Your Business Before Getting Married?

Starting a business before marriage does not automatically keep it out of property division in a Wisconsin divorce. Unlike in some states, property you owned before marriage can still be subject to division.

However, the court can consider the property each spouse brought into the marriage when deciding how to divide the marital estate. This means the fact that you created and owned the business before getting married may still affect the final division.

Different rules may apply if the business or an ownership interest was received as a gift or inheritance, or if a valid marital agreement addresses how the business will be treated.

How Do Courts Determine the Value of a Business in Divorce?

Valuing a business for divorce purposes typically requires a professional business valuation. This process looks at things like the company's assets, income, market position, and future earning potential. Courts often rely on financial experts who can dig into your business's records and provide an objective valuation.

This valuation becomes the foundation for figuring out what your spouse might be entitled to. This could mean dividing other marital assets to balance things out. It could also mean requiring some kind of buyout arrangement.

Can You Protect Your Business With a Prenuptial Agreement?

This is one of the most effective tools available. This applies if you're getting married while already owning a business, or if you know you'll be starting one soon. A well-drafted prenuptial agreement can specify that your business, along with any future growth, stays your separate property regardless of what happens during the marriage.

Postnuptial agreements can serve a similar purpose. This applies if you're already married and want to protect a business you're planning to start or one you've already begun building.

What Steps Can Protect Your Business During Marriage?

Several practical steps can help protect your business interests, even without a prenuptial agreement in place. Helpful steps include:

• Keeping detailed financial records, separating business funds from personal or marital funds
• Avoiding using marital funds to invest in or grow the business when possible
• Paying yourself a reasonable salary rather than reinvesting all profits back into the company
• Considering a postnuptial agreement if you didn't have a prenup before marriage
• Consulting with an attorney early on to understand your specific risk factors

Taking these steps proactively can make a significant difference if you ever face a divorce down the road. Clear documentation makes it easier to argue certain portions of your business should remain separate.

What Options Exist if You're Already Facing Divorce?

Several options might help protect your interests if you're already going through a divorce and worried about your business. This can include negotiating a settlement where you keep the business while your spouse receives other assets of equal value. It could also mean arranging a buyout where you pay your spouse for their share over time.

Working closely with your attorney to present a strong valuation and negotiate strategically can make a meaningful difference in how much of your business you ultimately retain.
