How to Get Married in Illinois (2026)
Everything you need to know about marriage licenses, requirements, costs, and planning your wedding in Illinois. Illinois anchors its wedding scene with Chicago's iconic skyline venues and then surprises with scenic wine country, historic mansions, and pastoral farm settings downstate.
Chicago dominates Illinois wedding culture with its Lakefront venues, River North event spaces, and rooftop receptions above Michigan Avenue, but the city's union service premiums add 18 to 22% to catering costs before gratuity. Couples who look at the Morton Arboretum in Lisle or Galena's Eagle Ridge Resort find comparable elegance 30 to 60 minutes outside the city at meaningfully lower venue fees. Illinois has a 1-day waiting period after the license is issued, which is short but means same-day ceremonies are not permitted.

Wait 1 day
After receiving your license, you must wait 1 day before the ceremony. Your license is valid for 60 days after issuance, so plan your ceremony date within that window.
Choose Your Officiant
In Illinois, your wedding can be officiated by ordained ministers, priests, rabbis, and leaders of any religious body. Make sure your officiant is properly authorized before the ceremony.
Hold Your Ceremony
Have your ceremony at your chosen Illinois venue. You will need 1 witness present at the ceremony.
File Your Marriage Certificate
After the ceremony, your officiant will sign the marriage license and return it to the County Clerk. Once filed, you will receive your official marriage certificate. This is your legal proof of marriage.
Illinois Wedding Planning Tips
Chicago summer weekends are the most competitive so consider a fall wedding for better availability and pricing
Lake Michigan breezes keep Chicago cooler than inland areas but can make outdoor ceremonies windy
Galena in northwest Illinois is a hidden gem for destination-style weddings just 2.5 hours from Chicago
Illinois requires a license from the specific county where the ceremony will take place, so confirm your county before applying since the license is not valid statewide.

What Makes Getting Married in Illinois Unique
Illinois weddings are dominated by Chicago and divide between Lakefront and River North urban venues, North Shore suburban estates, and the increasingly popular wine country around Galena and the Shawnee National Forest in the south. Chicago union labor rules add a real cost premium of 18 to 22 percent on catering and bar service at most major venues, which couples should account for in budgets. The Morton Arboretum in Lisle, the Field Museum, and Galena's Eagle Ridge Resort offer three very different aesthetics. Illinois has a 1 day waiting period after the license is issued. Outside Chicago, prices drop quickly, and the Shawnee Hills wine trail has built a real downstate wedding scene.
Illinois Marriage Law: What You Need to Know
Illinois has a 1-day waiting period after the license is issued, which means the license cannot be used until the calendar day after application. The license fee is around $60 in most counties and the license is valid for 60 days. A critical logistical detail is that the license is only valid in the county where it was issued. Couples must apply at the county clerk's office for the county where the ceremony will take place. Cook County, which includes Chicago, allows online appointment scheduling and has a relatively efficient processing system. Illinois allows county clerks to perform civil ceremonies at the clerk's office, which provides a low-cost option. Non-resident couples have the 1-day wait waived, which is a meaningful benefit for destination couples coming to Chicago for the event.

Illinois Wedding Season: What Locals Know

September and early October weekends are the single most competitive booking event because of the temperate weather and active lake activity. December through March is workable indoors but outdoor logistics shut down across the state.
Illinois-Specific Wedding Questions
How does the Illinois marriage license waiting period actually work?
Illinois has a 1 day waiting period after license issuance before the ceremony can take place. The license fee is $60 in Cook County and varies by county elsewhere. The license is valid for 60 days and only valid in the county of issuance. Couples must apply in the county where they intend to marry, which is a critical detail when picking suburban Cook versus city of Chicago.
Why are Chicago wedding costs so different from suburban Illinois?
Chicago union labor rules require union catering, bar, and event staff at most major venues, which adds roughly 18 to 22 percent to the catering subtotal before gratuity. Suburban venues outside Cook County, including those in DuPage and Lake counties, run union-optional and meaningfully lower. The same wedding in Naperville often runs 20 to 30 percent below the equivalent Chicago Loop or Streeterville event.
Is Galena a real Illinois wedding destination?
Yes. Galena, in far northwest Illinois near the Mississippi River, has become a meaningful weekend destination thanks to Eagle Ridge Resort and a walkable historic downtown. Couples from Chicago and the Twin Cities use it as a 2 to 3 day wedding weekend that does not require flights. Peak fall weekends book 12 to 18 months in advance.
What happens if an Illinois marriage license expires before the ceremony?
Illinois marriage licenses are valid for 60 days from the date of issuance. If the ceremony does not take place within that window, the license expires and a new license must be obtained from the county clerk. There is no grace period, and an expired license cannot be reused or extended. The couple must reapply, pay the fee again, and observe the 1-day waiting period again. Couples who apply well in advance of a peak-season date should calculate the exact expiration date and confirm it falls after the ceremony date before leaving the clerk's office.
