We fill out every government form for you, free, including SS-5 for Social Security and DS-82 / DS-11 for your passport.

Illinois-Specific Details
Illinois requires name change petitions to be filed in the circuit court where you've resided for at least six months. Major courts handling these cases include the Circuit Court of Cook County in Chicago, the Circuit Court of DuPage County in Wheaton, and the Circuit Court of Will County in Joliet. The $350–$400 filing fee varies slightly by county, with Cook County typically at the higher end due to additional administrative costs.
Publication requirements in Illinois mandate posting your name change notice in a local newspaper for three consecutive weeks. Popular publications for legal notices include the Chicago Tribune and the Herald & Review, with costs typically ranging $60–$150 depending on circulation and location. One notable Illinois quirk involves military service members: active duty personnel can petition in any Illinois county regardless of residency requirements, and some counties offer fee waivers for those demonstrating financial hardship through an indigency affidavit.
For driver's license updates, Illinois residents visit any Secretary of State facility without appointments, paying a $30 replacement fee. The state has embraced progressive gender-marker policies, allowing self-attestation for changes and offering a nonbinary "X" option since 2020. The Chicago North facility on Elston Avenue typically sees shorter wait times on Tuesday and Wednesday mornings, while suburban locations often process updates faster than downtown offices. New licenses arrive by mail within 2-3 weeks, and Illinois has been REAL ID compliant since 2020, so your updated license will meet federal requirements automatically. Certified copies of your court order typically cost $9–$15 each, and most people need about four copies for various agencies. Estimate your total at our cost calculator.
Pick Your Illinois Name Change Path
Each path has its own paperwork, court involvement, and timeline. Tap a card to see how it works in Illinois, then jump to the full guide.
Marriage Name Change in Illinois
In Illinois, your certified marriage certificate is your legal name change document — no court filing, no publication, no extra fees beyond $15 for the first copy and $2 for each additional one.
How it works in Illinois:
- Get certified copies of your marriage certificate. Order at least 3-4 copies from the county clerk where you were married. Illinois charges $15 for the first certified copy and $2 for each additional copy.
- Update your Social Security record first. Visit your local SSA office with your current driver's license, certified marriage certificate, and citizenship documents. SSA name change is free and takes 2-4 weeks for your new card to arrive. Other agencies verify against SSA records.
- Update your Illinois driver's license. Once you receive your new Social Security card, visit a Secretary of State facility with your current license, marriage certificate, and new Social Security card. The fee is approximately $30. Wait 24-48 hours after SSA so records sync.
- Update your passport. Passport via DS-82 if your current passport was issued within the last year, or DS-11 if it's been longer. Mail-in renewal costs $130 for a passport book.
Illinois doesn't require you to change your name when you marry — it's entirely your choice. You can keep your prior name, take your spouse's name, hyphenate, or even create a combination name (though the last option requires a court order). No court appearance, no publication requirement.

Divorce Name Change in Illinois
Illinois offers two paths: name restoration written into your divorce decree (free, easy), or a separate circuit court petition after the divorce is final.
Name restoration in divorce decree (recommended): Request name restoration in your original divorce petition or response. Include language like "Petitioner requests restoration of former name [your prior name]." The judge will typically grant this without additional hearings, and your final divorce decree will include the name change order. There's no additional fee beyond your divorce filing costs, and the process adds minimal time to your overall divorce timeline.
Separate name change after divorce: If your decree didn't include name restoration, you'll need to file a separate petition for name change with the circuit court. This follows the same process as a standard court-ordered name change, including filing fees ($200-400, varies by county), possible newspaper publication requirement, court hearing (usually brief and routine), and a 6-10 week timeline from filing to final order.
Your certified divorce decree serves as proof of your name change for updating documents with government agencies, banks, employers, and other institutions. Make sure to order several certified copies from the court clerk — you'll need them throughout the update process.
To change to a brand-new name (not restoration), use the court-ordered name change process below.

Court-Ordered Name Change in Illinois (Adult)
For any name change that's not through marriage or divorce. File a petition at your county Circuit Court ($350–$400), publish for 3 consecutive weeks, then attend a brief hearing. 6–10 weeks total.
A court-ordered name change in Illinois is required when you want to change your name for reasons other than marriage or divorce. This includes personal preference, cultural reasons, gender identity affirmation, or other life circumstances.
1. File your petition. File in the circuit court of the county where you've lived for at least 6 months. Illinois doesn't have a standardized name change form — each county may have slightly different requirements. Contact your local circuit court clerk for the specific forms and filing fee (typically $200-400).
Your petition must include:
- Your current legal name and the name you want
- Your address and length of residence in Illinois
- Reason for the name change request
- Statement that the change isn't for fraudulent purposes
- Any criminal history or pending legal proceedings
2. Background check and publication. Most Illinois counties require a criminal background check and publication of your name change request in a local newspaper for three consecutive weeks. The publication requirement gives the public notice of your intended name change. Publication costs vary but typically run $100-200.
3. Attend your court hearing. After publication is complete, you'll have a brief hearing before a judge. These hearings are typically routine — the judge will verify your identity, confirm you've met all requirements, and ensure the name change isn't for illegal purposes. Most hearings last less than 10 minutes. Bring photo ID and any supporting documents related to your name change reason.
4. Get your court order. Once the judge grants your petition, you'll receive a court order officially changing your name. Order at least 5-6 certified copies from the court clerk — you'll need these to update all your documents and accounts.
Publication exceptions: Some counties may waive publication requirements in specific circumstances, such as domestic violence situations or safety concerns.

Minor Name Change in Illinois
Illinois requires both biological parents' consent for minor name changes; if the child is 14 or older, many counties require the minor's consent too. Filed at the Circuit Court in the child's home county.
Changing a child's name in Illinois requires additional steps to protect the minor's interests and parental rights.
Consent requirements: Both biological parents must consent to the name change, even if one parent doesn't have custody. If both parents aren't available to consent, you may need to demonstrate:
- The absent parent has abandoned the child
- The absent parent's parental rights have been terminated
- The absent parent cannot be located after diligent effort
- The name change serves the child's best interests
Filing process: The petition process is similar to adult name changes but includes additional protections:
- File in the county where the child lives
- Include both parents' information and consent
- Explain why the name change benefits the child
- Pay filing fees (varies by county, typically $200-400)
- Publication may be required depending on county rules
If the child is 14 or older, many counties require the minor to consent to the name change as well. The judge will consider the child's wishes along with other factors.
Common situations: Minor name changes often occur when a parent remarries and wants the child to share the stepparent's surname, when paternity is established and the child wants the father's name, when the child's birth name causes significant problems or embarrassment, or for gender identity affirmation for transgender minors. The court's primary concern is always the child's best interests, not the parents' preferences.

Gender Identity Name Change in Illinois
Illinois is among the most supportive states for gender-affirming changes. DMV self-attestation (M / F / X), no medical documentation required, and confidential proceedings for safety concerns.
Illinois is among the most supportive states for transgender and non-binary individuals seeking name and gender marker changes. The process combines name change procedures with updated identity documents.
Legal name change for gender identity: Follow the standard court-ordered name change process above. Illinois courts generally approve gender-affirming name changes without requiring medical documentation or proof of transition. Your petition should clearly state that the name change is for gender identity purposes. Some counties may waive publication requirements for transgender petitioners due to safety concerns. Ask your court clerk about confidential proceedings if you have safety concerns about public notice.
Gender marker updates by document:
- Driver's License / ID: Self-attestation only. No court order or medical documentation required. Illinois recognizes male (M), female (F), and non-binary (X) markers. Visit any Secretary of State facility with your current license, completed application indicating your correct gender marker, and the standard $30 license fee.
- Birth Certificate: Illinois allows birth certificate gender marker changes for people born in the state. You'll need a court order for name change (if applicable), a physician's letter confirming appropriate clinical treatment (not necessarily surgery), and an application and fee to the Department of Public Health. The process typically takes 4-6 weeks. Updated birth certificates don't show any indication of the previous gender marker.
- Passport: Accepts self-selected gender markers. Use your court-ordered decree for both name and gender marker updates.
Combining name + gender marker: You can update your gender marker when you update your name, or separately if your name isn't changing. Request both in a single court petition to save time and fees.
