Cook County Marriage Certificate Request: In Person, Mail, or Online

To get a certified copy through a Cook County marriage certificate request, submit the couple’s full names, the marriage date, the Cook County municipality where the license was issued, and your government-issued photo ID to the Cook County Clerk’s Bureau of Vital Records. You can file in person, by mail, online through VitalChek, or by phone. The first certified copy costs $15, and each additional copy ordered at the same time is $4.¹

Who Can Ask for a Copy

Illinois keeps marriage records confidential until they are 75 years old. Once a record hits that threshold, it can be made available for public inspection through the Illinois State Archives and approved repositories; newer records stay restricted.² The Clerk issues copies of newer records to eligible individuals, which generally means either spouse named on the record, a legal representative with proper authorization, or someone with a court order.¹

Requesting on behalf of someone else? Bring a notarized authorization letter or the relevant court order along with your own ID.

What to Have Ready Before You Submit

Mismatched or incomplete information is the most common reason requests get kicked back. Have this in front of you before you start the form:

Full legal names of both spouses as they appeared at the ceremony, including any maiden names.
The exact date of the marriage, not an approximate range.
The Cook County municipality or village where the license was issued.
A valid government-issued photo ID: current driver’s license, state ID card, or U.S. passport. Present the original in person or send a legible photocopy with a mail request.

The Clerk’s office checks your ID against the names on the application to confirm you’re authorized to receive the record. If the name on your ID no longer matches the name on the certificate because of a legal name change, bring documentation bridging the two names, such as a court order or a later marriage certificate.

Requesting in Person

Walking in is the fastest route. The downtown Chicago vital records office is open Monday through Friday, 9:00 a.m. to 5:00 p.m., and the Clerk also runs suburban satellite offices around Cook County. Bring your completed request form and photo ID to the counter, pay the fee, and you can typically leave with the certified copy the same day.

In-person requests accept cash, credit cards, and debit cards. You can also buy marriage certificates at participating currency exchanges in the Chicago area, which can be more convenient than a trip to a Clerk’s office.

Requesting by Mail

Download the marriage and civil union record request form from the Cook County Clerk’s website, or send a letter that includes both spouses’ names, the marriage date, and the location. Include a legible photocopy of your government-issued photo ID and a self-addressed stamped envelope for the return.

Pay by check or money order made payable to the Cook County Clerk. Do not send cash. Send everything to the Cook County Clerk’s Bureau of Vital Records at the downtown Chicago office, and check the current mailing address on the Clerk’s website before dropping it in the mail, since office locations can shift. Allow several weeks for processing and delivery.

Requesting Online or by Phone

VitalChek is the authorized online ordering service for Cook County marriage certificates.³ Enter the marriage details on VitalChek’s site, upload a copy of your photo ID, provide payment information, and submit an electronic signature certifying you’re an eligible requester. Phone orders go through 866-252-8974.

VitalChek charges its own processing fee on top of the $15 base price, shown at checkout before you finalize payment. If you’re ordering multiple copies, that surcharge stacks up, and in-person or mail requests avoid the third-party fee entirely.

Fees

The Cook County Clerk charges $15 for the first certified copy of a marriage certificate and $4 for each additional copy ordered at the same time. A commemorative certificate suitable for framing is $65.¹ Online orders through VitalChek add a service fee on top of the base price.³

Order extras upfront if you know you’ll need copies for a name change, a passport, and an insurer. Three additional copies at $4 each is $12; a second $15 request later is not.

How Long It Takes

In-person requests are same-day once staff verifies your information. Mail and online orders typically take two to four weeks to arrive, depending on the Clerk’s current workload and mail transit. VitalChek offers expedited shipping at checkout for an added charge, which speeds up delivery but not the Clerk’s internal processing.

If you’re working against a deadline, go in person. If you’re using mail or online, build in the extra weeks.

Civil Union and Gender-Updated Certificates

The same request process, fees, and eligibility rules cover civil union certificates: $15 for the first copy and $4 for each additional copy.¹ The Illinois Department of Public Health does not hold civil union records, so requests go to the county clerk where the civil union took place.⁴

The Clerk also issues gender-updated or nongendered certificates for $15.¹ Contact the office directly to request an updated marriage or civil union certificate reflecting a gender marker change on other legal documents.

If You Need It for Use Abroad

The Clerk’s certified copy is the record itself. It is not the international authentication some foreign governments require. For that, you apply separately to the Illinois Secretary of State for an apostille under the Hague Convention, and that office will not apostille a photocopy or an uncertified document, so get the certified copy from the Clerk first.⁵

Fixing an Error on the Certificate

If you spot a misspelled name, wrong date, or incorrect location on your certificate, Illinois does not have a simple administrative amendment process the way some states do. Call the Cook County Clerk’s office and explain the specific error. Staff may be able to address minor clerical mistakes internally. If they cannot, they will direct you toward filing a petition in court. If the office denies the correction, ask for a written refusal letter; you’ll need it as documentation if you pursue the matter through the courts.
