When Should I File My Illinois Divorce?

 Posted on September 24, 2026 in Illinois Divorce

There is no single best time for everyone to start the divorce process. In some cases, the petition can and should be filed right away, but in other situations, it may be better for financial reasons to hold off for a bit before legally initiating your intention to end your marriage. If you're planning to divorce in 2026, our Kane County, IL divorce attorneys can help you decide when to move forward. At Weiler & Associates, P.C., we’ll ensure your rights are protected and that you fully understand every decision you make along the way.

Do You Have to Be Separated Before Filing for Divorce in Illinois?

You do not have to live apart before filing for divorce in Illinois. Under 750 ILCS 5/401, irreconcilable differences must have caused the breakdown of the marriage. If you and your spouse live separate and apart for at least six continuous months immediately before the divorce judgment is entered, the law conclusively presumes that the irreconcilable differences requirement has been met.

Illinois also has a residency requirement. One spouse must have lived in Illinois, or been stationed in the state as a member of the armed services, for at least 90 days before the case begins or before the court makes its required finding.

How Does the Timing of an Illinois Divorce Affect Property Division?

When a couple is married, they amass what is referred to as their marital estate. This can include real estate, financial accounts, household property, and vehicles.

Illinois is an equitable distribution state, which means the court divides marital property fairly during a divorce. However, fair does not always mean an equal 50/50 split.

According to 750 ILCS 5/503, property acquired by either spouse during the marriage is generally marital property unless it falls under an exception. This makes it important to understand what property you own before deciding when to file. A valid prenuptial or postnuptial agreement can also affect how property is handled during the divorce.

Does Filing for Divorce Stop New Property From Becoming Marital Property in Illinois?

Filing for divorce does not automatically make new property separate. You remain legally married until the court enters the divorce judgment.

Illinois law lists several types of non-marital property. These include certain gifts and inheritances, property owned before marriage, and property acquired after a judgment of legal separation.

A legal separation is different from simply living in separate homes. Moving out does not change the classification of property in the same way as a judgment of legal separation.

Can an Expected Work Bonus Affect When You File for Divorce in Illinois?

If you or your spouse expects a work bonus, it is worth reviewing the payment before filing for divorce. The timing of a bonus and the right to receive it can affect whether it becomes part of the marital estate.

In the 2013 case In re Marriage of Wendt, the husband's employer had control over whether he would receive future bonuses. The court found that the bonuses were not marital property because he had no enforceable right to receive them before the divorce.

A bonus that has already been earned or guaranteed can present a different situation. Before deciding when to file, your attorney can review the bonus plan and when the employee gained the right to the payment.

Can You Get Temporary Financial Help After Filing for Divorce in Illinois?

Under 750 ILCS 5/501, filing for divorce allows you to ask the court for certain types of temporary relief while the case is pending, such as temporary spousal maintenance or child support. The court can also address certain concerns involving marital property while the divorce is underway.

Temporary relief can be relevant if you cannot cover your regular expenses or your spouse controls much of the marital money. These orders last while the divorce is pending, but they do not decide the final outcome.

What Should You Consider Before Filing for Divorce in Illinois?

The timing of your divorce can affect both your finances and your daily life. Before filing, take stock of what is happening now and any major changes you expect soon.

Important issues to discuss with your attorney can include:

• Whether you expect to receive a work bonus or other large payment
• Whether you need temporary child support or maintenance
• Whether your spouse controls important marital accounts or assets
• Whether a major financial transaction is expected soon

It can also help to gather recent bank statements and other financial records. Having this information available can give your attorney a clearer picture of your finances before the divorce begins.
