How Is Marital Property Divided Under Illinois' Divorce Laws?

 Posted on September 17, 2026 in Property Division

Marriage is like a knot, and that knot can be very tricky to untie if you are getting a divorce. One of the most difficult parts of divorce can be the division of property. Some states use community property laws, which generally treat property acquired during a marriage as equally owned by both spouses. Illinois does not use this system. Instead, marital property is divided fairly based on the facts of the case. This is called equitable distribution, but it does not always result in an exact 50-50 split.

Having a skilled attorney at your side during a divorce is critical for protecting your rights to property. At The Stogsdill Law Firm, P.C., our Wheaton, IL family lawyers have over 100 years of experience, and we are no strangers to complex, high-value marital estates.

What Is the Difference Between Marital and Separate Property in Illinois?

There are two types of property that a married couple may own: marital property and separate property. Marital property generally includes assets and debts acquired by either spouse during the marriage. It usually does not matter whose name appears on the title or account. Some property acquired during the marriage remains separate. This includes gifts or inheritances given only to one spouse and property excluded by a valid agreement. Property owned before the marriage is also usually separate.

Marital property can include physical items and other types of assets. Examples include vehicles, furniture, clothing, jewelry, bank accounts, real estate, retirement benefits, and business interests. Credit card balances, mortgages, and auto loans can also be treated as marital debts based on when and why they were taken on.

Keep in mind that separate property can be mixed together with marital property if you're not careful. This usually happens when separate funds are deposited into a shared account. Also, if a spouse puts work into a piece of separate property that causes it to substantially grow in value, the marital estate could be paid back for those efforts (750 ILCS 5/503).

How Do Illinois Judges Divide Marital Property in 2026?

In many cases, divorcing spouses are able to work together to determine how to divide their marital property. If an agreement cannot be reached, the decisions about how to divide the property may be left up to a judge. Some of the factors the judge may consider are:

• What each spouse contributed to acquiring, maintaining, or increasing the value of the property, including work as a homemaker
• How long the marriage lasted
• Any obligations and rights arising from a prior marriage for either spouse
• The income of each party
• The tax consequences of the property allocation

If your divorce goes to trial, our firm is ready to advocate for a fair division of property based on your specific needs.

Can a Prenuptial or Postnuptial Agreement Decide How Property Is Divided?

A prenuptial or postnuptial agreement can decide how property is divided in an Illinois divorce. A prenuptial agreement is signed before the wedding. A postnuptial agreement is signed after the couple is already married. Both can list what property stays separate and what property is shared.

For an agreement to hold up, it should be in writing and signed by both spouses. Each person should receive honest information about what the other owns and owes before signing. A court can refuse to enforce an agreement if one spouse was pressured into signing it or if the agreement does not meet Illinois legal requirements. The exact rules are different for prenuptial and postnuptial agreements, so an attorney should review the document before it is signed.

Some terms cannot be settled in advance. For example, an agreement cannot limit child support or lock in parenting time. A judge reviews those issues based on the best interests of the child at the time of the divorce.

Does Spousal Maintenance Affect Asset Division in Illinois?

Spousal maintenance and property division are closely linked in Illinois. When deciding whether maintenance should be paid, the judge considers the property and debts assigned to each spouse. When dividing marital property, the judge can also consider whether the property division will be in addition to or instead of maintenance. Receiving a larger share of the property does not automatically prevent a spouse from receiving maintenance. The outcome depends on the couple’s full financial situation.

When Is Litigation Necessary for Property Division?

Many couples settle property division without a trial. Negotiation, mediation, and settlement meetings resolve the issue in a large number of cases. Litigation becomes necessary when the couple cannot agree on value or ownership, or when one spouse refuses to share honest financial information.

Litigation opens the door to formal discovery. Discovery is the process of gathering evidence under court rules. It can include written questions answered under oath, requests for documents, and depositions. Attorneys can subpoena bank statements, tax returns, business records, credit card history, and retirement account balances. When a business or a complex estate is involved, a forensic accountant or a valuation expert may be brought in to review the numbers.

Discovery has real value when a spouse is hiding income or quietly moving money. That being said, it also comes at a cost. Time spent on motions, subpoenas, and hearings can increase legal fees and reduce the money available to one or both spouses. Contested cases can also last for months. Reaching an agreement is often cheaper and gives both spouses more control over the result.
