Illinois Name Change Checklist After Marriage

Follow this sequence in Illinois:

• 1. Certified marriage certificate: order copies from the Office of the County Clerk (in the Illinois county where the marriage occurred) - the Illinois Dept. of Public Health Division of Vital Records does NOT hold marriage records and cannot issue certified copies.
• 2. Social Security (SS-5): free, and always first.
• 3. Wait 24–48 hours for the SSA record to sync.
• 4. Illinois Secretary of State (ILSOS) - Driver Services: update your license ($5 for a corrected driver's license; $10 for a corrected state ID card).
• 5. Passport: DS-82, DS-11, or DS-5504.
• 6. Voter registration & everyone else: bank, employer, insurers.

Mind the clock: Illinois asks you to update your license within 30 days of your legal name change, so don't park this step for later. The 30 days is the statute's window for applying for a corrected card after a legal name change (625 ILCS 5/6-116, which gives 10 days for a change of address). Illinois's own Secretary of State page says to notify it of an address or name change within 10 days, so to match the agency, do it within 10 days. The law: 625 ILCS 5/6-116(b).

• Certified copy of marriage certificate (from the county clerk where married)
• Current Illinois driver's license or state ID
• Updated Social Security card reflecting the new name
• A second document linking the old and new name (e.g., passport, birth certificate) if not otherwise clear
• Proof of Illinois residency (two documents, e.g. utility bill/lease) if also completing a REAL ID upgrade

Good to know for Illinois: Illinois marriage certificates are recorded and certified only at the county clerk level, not by the state. IDPH's Division of Vital Records can only provide a $5 verification-of-facts letter (names, DOB, event date/place) for marriages from 1962 onward, by mail/fax/in-person - not an official certified certificate.

• Certified marriage certificate (3 copies, at typical prices): $30–$90
• Social Security card (Form SS-5): Free
• Driver's license update (Illinois Secretary of State (ILSOS) - Driver Services): $5 (driver's license)
• Passport (only if you update it): Free–$165
• Voter registration: Free

Most people spend roughly $35–$260 in Illinois: on the low end if you skip the passport, on the high end with a full passport renewal and extra certificate copies.
