## How to legally change your name in Illinois
There are several paths to a legal name change — each with different procedures, costs, and timelines.
## The five main paths
**1. Marriage.** Easiest path. Use the marriage certificate as your name-change documentation:
- No court order needed
- Show certificate to Social Security, DMV, employer, banks
- Most states allow either spouse to change name
- Hyphenation, combining names, or new entirely-different name (varies by state)
**2. Divorce.** Restore prior name as part of divorce decree:
- Request restoration in the divorce petition
- Decree includes the name change
- Use decree for documentation
- No separate proceeding needed
**3. Adoption.** Adoption decree changes child's name automatically.
**4. Common-law name change.** In many states, you can use a new name in everyday life if there's no fraudulent intent. BUT — most government IDs, banks, and employers require a court order or marriage / divorce decree before they'll change records. Practically not useful.
**5. Court-ordered name change.** Required path for adults who aren't getting married or divorced and want a different name.
## Court name-change petition process
1. **File petition** in proper court (usually probate / circuit / civil court depending on state)
2. **Pay filing fee** ($100-$500 typical)
3. **Background check** — fingerprints submitted; many states reject petitions with criminal history
4. **Public notice** — publish notice in newspaper for several weeks (varies; some states waive for safety reasons)
5. **Hearing** — judge confirms identity, asks reasons, checks for fraud
6. **Court order** — official document with new name
7. **Update records** — Social Security first, then DMV, passport, financial accounts
## Common reasons for name change
- Personal preference / disliking current name
- Religious / spiritual reasons
- Cultural / heritage reasons
- Aligning name with gender identity (transgender / nonbinary)
- Returning to maiden name without divorce
- Removing names of biological parents who weren't involved
- Adopting a stepparent's name
- Anglicizing or de-anglicizing a name
- Honoring a relative or mentor
- Pen name / stage name (limited utility)
## Common grounds for denial
- **Fraudulent intent** — escaping debts, creditors, criminal liability
- **Avoiding child support / divorce obligations**
- **Sex offender status** (varies by state)
- **Open felony cases**
- **Inappropriate name** — racial slurs, profanity, names that suggest royalty/title in some states
- **Numbers, symbols, single letters** in some states
- **Identity theft concerns**
## Sex-offender registry implications
Many states require sex-offender registrants to:
- Notify law enforcement BEFORE filing for name change
- Continue using legal name in registry
- May face additional restrictions on changes
## Confidential / sealed name changes
Most states allow sealed / confidential name changes for:
- Domestic violence survivors
- Sex trafficking survivors
- Stalking victims
- Witnesses needing protection
Court files sealed; publication waived; address kept confidential.
## Transgender name changes
Most states have streamlined transgender name-change procedures. Some states allow combined name + gender-marker changes in single petition.
**Federal** — passport gender markers and name changes require court order or other documentation; recent administrative streamlining helps.
**State ID / driver's license** — varies; some states require physician statement; others self-attestation.
**Birth certificate** — varies dramatically; many states still restrictive.
## Costs
Typical adult name-change costs:
- Filing fee: $100-$500
- Fingerprinting / background check: $25-$75
- Newspaper publication: $50-$300
- Certified copies of order: $5-$25 each
- Attorney fees (optional): $400-$1,500
- New IDs / documents: $20-$200+
Most states have indigent fee waivers.
## Updating records after the order
Recommended order for record updates:
1. **Social Security card** — get this first; everything else flows from it
2. **State ID / driver's license**
3. **U.S. passport**
4. **Voter registration**
5. **Bank accounts**
6. **Credit cards / loans**
7. **Employer + payroll**
8. **Insurance — health, auto, life, home**
9. **Investment accounts / retirement**
10. **Vehicle title / registration**
11. **Property deeds**
12. **Utilities / cellphone / streaming services**
13. **Professional licenses**
14. **Education records / transcripts**
15. **Beneficiary designations**
16. **Will / trust / power of attorney** (have attorney update)
## Children's name changes
Minor name changes typically require:
- Both parents' consent (or notification)
- Best-interests-of-child analysis
- More detailed reasons
- May require child's appearance (age-dependent)
Disputed minor name changes are more difficult — particularly when one parent objects.
## What you should do
Illinois name changes are usually DIY-able for adults. Most Illinois clerk's offices have packets with all forms needed. Hire an attorney for: confidential / sealed petitions, criminal-history concerns, contested minor name changes, transgender-with-gender-marker combined petitions. Most Illinois family-law attorneys offer flat-fee name-change packages.
