Illinois Divorce Name Change Checklist

Under 750 ILCS 5/413, your Illinois divorce decree should include a clause authorizing you to resume your former or maiden name—no separate court petition required. Start by updating Social Security with Form SS-5 and your certified divorce decree, which takes 10-14 days. Then update your Illinois driver's license ($5), passport, banks, and other accounts using the decree as proof.

No separate court order is required in Illinois if your divorce decree includes the standard name restoration provision under 750 ILCS 5/413. Illinois law mandates this clause unless you specifically request otherwise. If your decree lacks this provision, file a motion to amend rather than starting a new name change case—this avoids the publication requirements and $200+ filing fees of a standalone petition.

You need 3-5 certified copies of your divorce decree from the Cook County or applicable circuit clerk ($10-25 each). Each agency requires original or certified copies—photocopies are rejected. For Social Security, bring your decree plus valid photo ID. The Illinois Secretary of State requires your decree and current driver's license. Banks and passport applications also require certified copies.

Total costs range from $200-400 for all government fees in Illinois. Certified divorce decree copies cost $10-25 each. Social Security updates are free. Illinois driver's license correction costs $5 ($10 for state ID). Vehicle title changes cost $15. U.S. passport updates cost $130 with Form DS-82 or are free with DS-5504 if your passport was issued within one year.

Complete the full process in 4-8 weeks if you work efficiently. Social Security takes 10-14 days for your new card. Illinois law requires updating your driver's license within 30 days of your legal name change. IDFPR processes professional license updates in 2-4 business days. Passport renewals take 6-8 weeks for routine processing or 2-3 weeks expedited.

No, name change after divorce is entirely optional under Illinois law. The 750 ILCS 5/413 provision authorizes but does not require you to resume your former name. Many people keep their married name for professional continuity, to match their children's surname, or simply personal preference. You can change your name years later using the original divorce decree.

Illinois divorce courts cannot change a child's name—you must file a separate petition under 735 ILCS 5/21-101. Both parents must receive notice, and the non-custodial parent can object. Courts require clear and convincing evidence the change serves the child's best interests, a high legal standard. Even with sole custody, you cannot unilaterally change your child's legal name.

Update Social Security first—this is mandatory before any other name change in Illinois. Complete Form SS-5 and bring your certified divorce decree to your local SSA office or mail it. Your new Social Security card arrives in 10-14 days at no cost. The Illinois Secretary of State and all other agencies require your Social Security record to match your new name before processing updates.
