How to Change Your Name After Divorce in Illinois

In Illinois, changing your name after divorce is usually simple, because the law builds it into the divorce itself. Your judgment for dissolution of marriage automatically includes a provision letting you resume a former or maiden name, unless you ask the court to leave it out, and you can start using that name whenever you choose. You do not need a separate court case, a newspaper notice, or an extra filing fee. It only becomes more involved if your divorce is already final without that provision, or if you want a brand-new name rather than a former one.

This page walks through both paths: restoring a former or maiden name through your divorce, and the separate name-change petition you would use for anything else, plus how to update your records once the court signs off.

The Easy Path: Restoring Your Name in the Divorce

For most people, name restoration is part of the divorce in Illinois, not a separate errand. Under 750 ILCS 5/413^[1], your judgment for dissolution of marriage is supposed to include a provision authorizing you to resume your former or maiden name, unless you request otherwise. If it does, you are not required to file a separate name-change petition, and you are not required to publish a notice in a newspaper.

• What it covers. A name you previously held, typically your maiden name or a prior married name, not a brand-new name you have never used.
• When you can use it. Whenever you choose after the judgment is entered. There is no deadline. Some people switch right away, others wait months or years.
• What it costs. Because it is part of the divorce, there is no separate court fee for the restoration itself.

If Your Divorce Is Already Final

You still have straightforward options.

• Your judgment already has the provision. Then you are done legally. You simply use a certified copy of the judgment to update your records, covered below.
• Your judgment does not have the provision. This is uncommon now that the language is automatic, but if it is missing you can usually file a motion to amend your judgment for dissolution to add it, rather than running the full name-change process.
• You want a name that is not a former or maiden name. The divorce route does not apply, and you use the general name-change petition described next.

The Separate Route: A Name-Change Petition

For a brand-new name, Illinois uses a standalone process under the Code of Civil Procedure. It has a few more steps than restoring a former name.

Step 1: Meet the Residency Requirement

Under 735 ILCS 5/21-101^[2], you must be an Illinois resident who has lived in the state for at least 6 months, and you file in the circuit court of the county where you live.

Step 2: File the Petition

You file a petition on the statewide standardized form approved by the Illinois Supreme Court, stating your current name, the name you want, your residence, and how long you have lived in Illinois.

Step 3: Publish Notice

Under 735 ILCS 5/21-103^[2], you generally publish notice of the requested change in a local newspaper for 3 consecutive weeks, with the first notice at least 6 weeks before your hearing date. Limited exceptions apply, including for certain minors and, as noted, for resuming a former name after divorce.

Step 4: Attend the Hearing

You appear before a judge, who reviews the petition and, in most cases, grants the change. You then obtain certified copies of the name-change judgment to update your records.

Updating Your Records After the Name Change

A court order changes your legal name, but you have to notify everyone else, and the order in which you do it matters. Start with Social Security.

• Social Security Administration first, so your new name is on file before other agencies check against it.
• Illinois driver's license or state ID at the Secretary of State.
• U.S. passport, if you have one or plan to travel internationally.
• Everyone else: employer and payroll, banks and credit cards, insurance, retirement accounts, the post office, voter registration, and any titles or deeds.

Order several certified copies of the judgment. Many agencies will want to see one, and copies are easier to gather up front than after the fact.

Documents You'll Need

• A certified copy of your judgment for dissolution of marriage, with the name-restoration provision, or the name-change judgment if you used the petition route.
• A government-issued photo ID.
• Your Social Security card.
• For the petition route, the standardized name-change petition form and proof of Illinois residency.

Common Mistakes and Complications

• Assuming you need a separate case. Most people restoring a maiden or former name do not. It is already handled inside the divorce.
• Not confirming the provision is in your judgment. It is automatic unless you opt out, but it is worth checking that the restoration language actually appears before the judgment is entered.
• Trying to take a brand-new name through the divorce. The divorce route only restores a former or maiden name. Anything else needs the petition.
• Starting with the wrong agency. Update Social Security before the others to avoid name mismatches.
• Ordering too few certified copies. Several agencies each want their own.
