Dividing Intellectual Property in an Illinois Divorce

 Posted on February 26, 2026 in Divorce

During a divorce, most people think about how things like cars, real estate, and retirement accounts will be divided between the spouses. But, as our society becomes increasingly information-driven, another major category of property to be split is intellectual property. In a high net worth divorce, dividing these unconventional assets can be a major source of argument between the spouses.

What Is Intellectual Property?

Although intellectual property isn’t typically something tangible like a house or a car, it can sometimes be just as valuable, if not more. In simple terms, intellectual property includes ideas, creative works, inventions, and brand identities. If those ideas can be owned, sold, licensed, or used to make money, they may be considered property in a divorce.

Common Types of Intellectual Property Involved in an Illinois Divorce

Intellectual property shows up in more divorces than people expect. It is not limited to large companies or famous inventors. Many professionals and small business owners own valuable rights without realizing it. Common examples include:

• Patents for inventions or product designs
• Copyrights for books, music, software, artwork, or online content
• Trademarks tied to a business name or brand
• Trade secrets, such as formulas, client lists, or proprietary methods

In today’s economy, digital content is also important. A monetized YouTube channel, an online course, or a successful social media brand may have measurable value. Even if income has not yet peaked, future earning potential may be relevant.

Professional goodwill may also be considered. For example, a doctor, consultant, or entrepreneur may have built a reputation tied to a brand. That reputation can affect business value. While personal goodwill is often not divisible, enterprise goodwill connected to a business may be. 

Each type of intellectual property has different legal protections. That is why classification and ownership must be carefully analyzed in an Illinois divorce.

When Is Intellectual Property Considered Marital Property?

Illinois law has a broad scope of what is considered marital property. The presumption is that all property acquired during the marriage, that was not an individual gift or inheritance, is marital property. This includes typical types of personal property and real estate, as well as intellectual property.

If one spouse writes a book during the marriage, the copyright on that book is presumed to be marital property. There are exceptions to this rule and ways to rebut the presumption. However, the starting position of the court is that even intellectual property created or acquired during the marriage is marital property.

Some intellectual property starts before marriage but grows in value during the marriage. In that case, the increase in value may be partly marital. These situations can become complicated. Careful review of timelines, contracts, and financial records is often necessary.

How Can Intellectual Property Be Divided?

Illinois requires marital property to be split equitably. This does not mean that everything is split in half. Instead, it means that the marital property must be divided fairly under all of the circumstances (750 ILCS 5/503). Courts look at the following factors when deciding how to divide marital property:

• How each spouse contributed to the acquisition of marital property
• Contributions made as a homemaker
• The duration of the marriage
• The value assigned to each spouse’s share
• Any economic windfalls or hardships
• Child custody arrangements
• Health and age of the spouses
• Tax consequences
• Ability of each spouse to acquire assets and earn income in the future
• Any spousal maintenance awards

Intellectual property also falls under this analysis. For practical purposes when one spouse is the sole creator of the intellectual property, such as with a book, the courts often give the creator the copyright, but may give the non-creator spouse more tangible assets.

If the property is not worth much now, the court will have to consider what it could likely be worth in the future. If both spouses jointly created the intellectual property, one side may be awarded the property and ordered to pay a percentage of royalties to the other spouse on an ongoing basis.

Every case is different and the property division also depends on the valuation of the intellectual property.

How to Value Intellectual Property in 2026

Valuing intellectual property often requires expert input. Courts want real figures, not guesses. The process usually involves financial professionals who understand both business valuation and family law.

There are several common valuation methods. The income approach looks at how much money the asset generates or is expected to generate. This may include royalty payments or projected future earnings. The market approach compares the asset to similar intellectual property that has been sold. The cost approach considers how much it would cost to recreate the asset.

Future income can also factor into an asset’s worth. For example, a patent may not yet be profitable, but it could produce income for years once it is. Courts may consider reasonable projections. However, speculation alone is not enough. Financial records, contracts, licensing agreements, and past earnings all play a role.

Technology also changes quickly. Digital assets, artificial intelligence tools, and online platforms can increase or decrease value quickly. Market trends must be considered. What was profitable three years ago may not hold the same value today.

Intellectual property can affect long-term financial security, so a careful valuation is critical. A rushed or incomplete analysis can lead to an unfair division. Our firm can help you obtain a thorough estimate for the worth of your intellectual property so that you can negotiate with clarity and confidence.
