Does It Matter Which Spouse Files for Divorce in Illinois?

 Posted on October 29, 2026 in Divorce

Once divorce becomes a serious possibility, deciding when to file brings its own questions. Some spouses want to start the process quickly, while others worry about what happens if their partner files first.

Filing first does not give either spouse greater rights to property or support. However, it affects how the case begins and gives the filing spouse time to prepare before papers are served. If you are planning a divorce in 2026, our Naperville, IL divorce attorneys will explain your options and help you prepare.

Does Filing First Give You an Advantage in an Illinois Divorce?

The spouse who starts the case is called the petitioner. The other spouse is the respondent. Neither title gives the judge a reason to favor that person.

Property division follows Illinois’s rules for a fair division of marital assets and debts. Support decisions turn on the applicable financial standards. Decisions about children focus on their best interests.

For example, filing first does not give you priority to keep the family home or become the parent with more parenting time. You still need to establish why the outcome you request is appropriate.

The practical benefit is preparation. Before filing, you have an opportunity to review your finances and develop a plan with your lawyer. That preparation is more useful than simply winning a race to the courthouse.

Can Filing First Affect Where Your Illinois Divorce Takes Place?

According to 750 ILCS 5/104, a divorce belongs in a county where either spouse lives, subject to legal exceptions. If you live in different counties, the spouse filing the case chooses between the available locations.

For example, if you live in DuPage County and your spouse lives in another Illinois county, either location could be appropriate. Where the case proceeds affects travel and arrangements for required appearances.

You do not have an unrestricted right to choose any courthouse in Illinois. If your spouse files somewhere neither of you lives, have the location examined promptly. Waiting too long to object could prevent you from challenging it.

Do You Have to File for Divorce First to Request Temporary Support in Illinois?

Either spouse has the right to request temporary relief once the divorce case is pending. Under 750 ILCS 5/501, that includes temporary maintenance and child support. The court also has authority to issue orders protecting property when the requirements are met.

If your spouse has already filed, you do not need to start a separate divorce case to ask for help paying necessary expenses. Your attorney can bring the request in the existing proceeding.

Does the Filing Date Determine Property Values or Alimony in an Illinois Divorce?

The filing date does not automatically lock in the value of your property. According to 750 ILCS 5/503, assets are valued as of trial unless the spouses agree on another date or the judge orders one. An account’s balance when the petition was filed is therefore not necessarily the amount used in the final division.

Timing has a different role in maintenance (the term for alimony in Illinois). When maintenance guidelines apply, the length of the marriage at the start of the case helps determine how long payments last. Filing near a wedding anniversary could affect that calculation.

This does not mean that filing creates a right to maintenance. The judge must first decide whether an award is appropriate. Have the financial effect of a proposed filing date assessed before assuming that earlier or later is better.

What Should You Do if Your Spouse Files for Divorce First in Illinois?

Read the papers promptly and note when you received them. The summons explains what you must do to respond and the deadline that applies. Ignoring it puts your ability to participate at risk.

Before meeting with your attorney, gather:

• The petition and any court notices
• Recent income records and account statements
• Any prenuptial or postnuptial agreement
• Existing orders involving your children
• Documents identifying urgent financial or safety concerns

Tell your attorney which requests you dispute and what outcome you want instead. Continue watching for court notices after responding. Settlement discussions do not excuse missing a filing deadline or required appearance.
