FamilyCourtHelp is an independent educational platform. It is not a court, law firm, government agency, or government partner. We organize and link to publicly available resources published by courts and government agencies. Official requirements may change. Always confirm current requirements with the applicable court or clerk.
A name change in Illinois can come up inside a divorce, where a spouse asks to restore a former name, or as its own filing. Either way the court has to approve it in writing before the new name is official.
The official Illinois documents below cover the request. Once the order is signed, you normally take a certified copy to the agencies that hold your records.

In many states yes, if you ask for it before the final order is entered. Ask early, because reopening the case later is more work than including it up front.
Get certified copies of the order and take them to the agencies that hold your records. Each agency has its own process.
