What Happens to Your Share of a Family Business in an Illinois Divorce?

 Posted on November 08, 2026 in Property Division

Owning a business with relatives adds another concern when your marriage ends. You might worry about losing your share or bringing your spouse into a company your family built.

Your share of the business could be part of the property divided in an Illinois divorce, even if your spouse never worked there. If you own an interest in a family business and are divorcing in 2026, our Chicago, IL divorce attorneys will help you protect your financial interests.

Is Your Share of a Family Business Marital Property in Illinois?

Under 750 ILCS 5/503, an interest acquired during marriage is presumed marital, even if only your name appears on the ownership documents. Exceptions include shares received as a gift or inheritance.

An interest you owned before marriage is nonmarital unless later events change its status. Records showing when and how you acquired it help establish which rules apply. Being part of a family-owned company does not create a separate exemption from property division.

Does Your Illinois Divorce Affect Your Relatives’ Ownership Shares?

Your relatives’ shares do not become marital property simply because you are divorcing. The case concerns the interests belonging to you and your spouse.

For example, if you own 25 percent of a company with your siblings, the starting point is your ownership interest. The divorce does not give your spouse a claim to your siblings’ shares.

However, you also need to examine the company’s operating agreement. It could restrict transfers or require a buyout after divorce. Those provisions affect how your interest is handled, so your attorney should examine them before proposing settlement terms.

How Is Your Share of the Business Valued  During a Divorce in Illinois?

Illinois uses a fair market value standard when valuing property for divorce. A business valuation should examine your actual ownership interest. This includes the rights and limits attached to it.

A qualified valuation professional reviews the company’s finances rather than relying on a relative’s estimate. Records needed for that review include:

• Business tax returns
• Recent financial statements
• Ownership and operating agreements
• Records of business debts
• Details of payments to owners
• Any agreement governing the sale of shares

Annual revenue alone does not establish what your share is worth. The review must account for business expenses and obligations, along with the financial benefits your interest provides.

What if Marital Money or Work Helped a Nonmarital Business Grow?

A business you owned before marriage does not become marital property simply because it grows in value. However, using marital money to help it grow could require repayment to the marital estate.

For example, using joint savings to buy business equipment raises a reimbursement question. Records must show where the money came from and how it was used.

Work during the marriage also deserves a closer look. Reimbursement requires significant effort that substantially increased the business’s value.

If the marital estate already received reasonable payment for that work, such as through your salary, no additional reimbursement is required. These rules address contributions to the business without automatically giving your spouse an ownership share.

Do You Have to Sell Your Business Share During an Illinois Divorce?

A sale is not the only way to resolve a marital business interest. One spouse could retain the interest while the other receives other marital assets or an agreed payment.

Illinois requires a fair division of marital property, rather than an automatic equal split of each asset. The business must be considered within the overall financial settlement.

For example, keeping your ownership interest while your spouse receives a larger share of other assets could avoid a transfer. Before agreeing, consider whether enough property or cash is available to make that arrangement workable.

Any proposed transfer also needs to comply with applicable ownership restrictions. Receiving part of an interest’s value and becoming an owner are separate outcomes.
