Is Everything Really Split 50/50 in an Illinois Divorce? 

by | Sep 3, 2026 | Family Law

Many people going through a divorce assume that marital property will automatically be divided 50/50. In Illinois, that is not necessarily the case.

Illinois follows a principle known as equitable distribution, which means marital property is divided based on what is considered fair under the circumstances rather than automatically split equally between spouses.

But before property can be divided in an Illinois divorce, there is another important question: What is considered marital property?

What Is Considered Marital Property in Illinois?

Generally, property acquired during the marriage may be considered marital property. However, determining whether an asset is marital or non-marital is not always straightforward.

A home purchased during the marriage may be relatively simple to classify. Other assets can raise more complicated questions, including:

  • A business started before the marriage that increased in value during the marriage
  • An inheritance received by one spouse and later used for marital expenses
  • A retirement account funded both before and during the marriage
  • Property owned before the marriage that increased substantially in value
  • Bank or investment accounts containing both marital and non-marital funds

How an asset was acquired, how it was used, and what happened to it throughout the marriage can all be important when determining whether it is considered marital property.

What Is Non-Marital Property in an Illinois Divorce?

Certain assets may be considered non-marital property, including, in some circumstances, property acquired before the marriage, inheritances, and gifts made specifically to one spouse.

However, the way an asset is handled during the marriage can complicate its classification.

For example, questions may arise when inherited funds are placed into a joint account, marital funds are used toward property owned before the marriage, or a separately owned business grows during the marriage.

Determining whether an asset is marital or non-marital may require looking beyond whose name appears on the account, deed, or title.

Does Equitable Distribution Mean a 50/50 Split in Illinois?

No. Equitable distribution does not automatically mean an equal 50/50 division of marital property.

Once marital property has been identified, a number of factors may affect how the marital estate is ultimately divided. Depending on the circumstances, these may include the length of the marriage, each spouse’s financial circumstances, contributions to the marital estate, and other relevant considerations.

In some divorces, an equal division may be appropriate. In others, an equitable division may look different.

Why Property Classification Matters During Divorce

Understanding which assets are marital and which may be non-marital can have a significant impact on the financial outcome of a divorce.

This can be especially important when a marital estate includes assets such as:

  • Real estate
  • Businesses or ownership interests
  • Retirement accounts
  • Investments
  • Inheritances
  • Other significant or complex assets

Understanding how your property may be classified and divided can help you make more informed decisions as you navigate the divorce process.

Frequently Asked Questions About Marital Property in Illinois

Q: What is considered marital property in Illinois?

Q: What happens to a business during a divorce in Illinois?
