Can Text Messages and Emails Be Used as Evidence in an Illinois Divorce?

 Posted on April 09, 2026 in Divorce

If you are going through a divorce in 2026, there is a good chance that some of the most important conversations between you and your spouse happened over text or email. People talk about money, parenting, property, and personal matters in writing more than ever before. Pew Research suggests roughly 9 out of 10 households have a smartphone, and many everyday conversations now happen through texts and emails.

What many people do not know is that those messages can end up in front of a judge. That means there is a good chance that something you or your spouse has written is already sitting in someone's pocket, ready to be used in court. A Chicago, IL divorce attorney can help you understand how digital messages may affect your case and what you should do to protect yourself.

Are Text Messages and Emails Admissible as Evidence in an Illinois Divorce?

Text messages and emails can be used as evidence in an Illinois divorce, but they’re subject to certain conditions. First, the person offering the messages has to prove they are real. That means showing the messages were actually sent by the person they appear to be from and that nothing has been changed. A screenshot may be used, but the person offering it still has to show that it has not been altered.

Once that is established, texts and emails are treated like any other written evidence. Illinois courts have accepted digital messages in cases involving property division, spousal maintenance, and parental responsibilities.

What Parts of a Divorce Can Text Messages and Emails Impact?

Digital messages can come up in several parts of a Cook County divorce case.

Financial Misconduct and Asset Dissipation

If your spouse has been hiding money, making unusual purchases, or moving funds around, written messages can sometimes prove it. A text about a cash sale or an email from your bank about sending money could support a claim for dissipation of marital assets. Under 750 ILCS 5/503, Illinois courts look at dissipation of marital property when dividing assets in a divorce.

Parenting and Custody Disputes 

Messages showing missed parenting time, threats, or unstable behavior can matter when a judge decides what is best for your child. A pattern of hostile or alarming texts and emails can affect decisions about parental responsibilities, especially in high-conflict divorce cases.

Spousal Maintenance 

Sometimes messages show details about how a spouse is living, whether they are working, or who they are living with. Those details can affect whether maintenance should be paid and how much.

How Do Texts and Emails Become Part of an Illinois Divorce Case?

There are two main ways in which texts and emails can become a part of a divorce case. The first is through voluntary disclosure. If you already have messages on your own phone or a shared account, you can save and use them.

The second is through the formal discovery process. During discovery, your attorney can ask the other party to hand over relevant messages. Under Illinois Supreme Court Rule 214, parties can request texts, emails, and other stored electronic information.

What you cannot do is access your spouse's accounts or devices without permission. Getting into someone else's phone or email without consent can get you into legal trouble and may make the evidence useless in court.

Can Your Own Texts and Emails Hurt Your Illinois Divorce Case?

Everyone going through a divorce should be careful about what they put in writing. Texts and emails can be requested through discovery, and anything you send to your spouse can be used against you. Before you hit send on an angry text or a heated email, think about how those words would look in front of a judge. Courts have seen messages that hurt a parent's custody case, exposed hidden money, or contradicted sworn testimony. Something written in a hard moment can cause real problems later in your case.
