Can You Legally Change Your Name After Marriage in Illinois?

In most cases, you do NOT need a court order if you are:

Hyphenating your last names
Combining both surnames
However, you may need to file a court petition if:
You want to create a completely new last name
You are changing your first name
Your desired name is not supported by your marriage certificate
For standard surname changes, your marriage certificate is generally sufficient.
Documents You Should Gather Before Starting
Before you begin updating records, collect these essential documents:
Certified marriage certificate
Current Illinois driver’s license or state ID
Social Security card
Valid U.S. passport (if applicable)
Birth certificate (occasionally requested)
Smart Tip:
Order 3–5 certified copies of your marriage certificate from the county clerk’s office. Many institutions require original copies, and having extras helps avoid delays.
Keeping your documents organized in one folder makes the process much easier.
Step-by-Step Process to Change Your Name in Illinois
The order of updates is extremely important. Many agencies verify your identity using federal databases, so starting in the right place prevents complications later.
Step 1: Obtain Your Certified Marriage Certificate
After your wedding ceremony, your marriage license must be filed with the county clerk. Once it has been officially recorded, you can request certified copies.
This document serves as the legal foundation for your name change.
Estimated Cost:
Typically $10–$20 per certified copy, depending on the county.
When to Request It:
Wait about 7–14 days after your wedding to ensure the record has been processed.
Step 2: Update Your Social Security Record (Start Here First)
Always begin your name change with the Social Security Administration. Many state agencies verify your name through Social Security records.
What You’ll Need:
Completed Social Security name change application (Form SS-5)
Certified marriage certificate
Valid photo ID
Cost:
✅ Completely FREE
You can apply by mail or visit a local Social Security office in person.
After processing, you will receive a new Social Security card reflecting your updated name. Your Social Security number remains the same.

Around 10–14 business days.
Helpful Insight:
Once your Social Security record is updated, most other institutions can quickly confirm your new legal name, making future updates smoother.
Step 3: Update Your Illinois Driver’s License or State ID

Updating your primary photo ID early prevents confusion in financial and legal matters.

Proof that your Social Security record has been updated
You may receive a temporary paper ID while your permanent card is mailed.
Estimated Fee:
Usually around $5–$30, depending on the type of license and replacement timing.
Important Tip:
Complete this step soon after your Social Security update so your photo ID matches your legal name everywhere.
Step 4: Update Your Vehicle Title and Registration
If you own a vehicle in Illinois, your title and registration should reflect your legal name.
Visit a Secretary of State facility with:
Updated driver’s license
Marriage certificate
Vehicle title
Estimated Cost:
Generally $15–$50, depending on the type of change required.
Keeping vehicle records consistent prevents issues if you sell or transfer ownership in the future.
Step 5: Update Your Passport
If you travel internationally, updating your passport is important.
Costs depend on your passport status:
Recently issued passports may qualify for a free correction
Standard renewals typically cost $130–$165
Processing Time:
Usually 4–8 weeks, with expedited options available for an additional fee.
Travel Reminder:
Always book flights using the exact name printed on your passport.

Start With:
Employer and payroll department
Banks and credit cards
Insurance providers
Retirement and investment accounts

Utility providers
Mortgage or rental agreements
Professional licenses
Online subscriptions
