Access DuPage County Clerk Records

About the DuPage County Clerk

The DuPage County Clerk is listed in official county materials as Jean Kaczmarek. The County Clerk's office sits in the County Administration Building at 421 N. County Farm Road, just up the street from the courthouse and the jail. The Clerk's main number is (630) 407-5500, and the general county switchboard answers at (630) 407-6500. The County Clerk is one of two elected clerks in DuPage: court files go through the Clerk of the 18th Judicial Circuit Court, while vital records, elections, and county-government records go through the County Clerk.

Marriage records and certified marriage copies are the most common reason a DuPage resident contacts the County Clerk. The office also runs voter registration, issues some county licenses, posts election results, holds statements of economic interest for public officials, and supports tax-extension and GIS work. The official county website at dupagecounty.gov links each of these services from the County Clerk department page.

Records the DuPage County Clerk Keeps

The County Clerk has a specific records list under Illinois law. Court files are not on that list. Anyone who needs a divorce decree or a probate order should request it from the Circuit Clerk, not the County Clerk. The County Clerk does keep the records below.

• Marriage records - Marriage license issuance and certified marriage copies for DuPage marriages.
• Voter registration - Register, update, or check voter status for DuPage County.
• Election results - Certified election results for federal, state, county, and local races.
• Statements of economic interest - Filings by public officials in DuPage that must be available for public review.
• Tax extension - Tax extension and tax-rate work that feeds the county property-tax cycle.
• Maps and GIS - Election district and precinct maps tied to the County Clerk's election duties.
• Notary commissions and assumed business names - Where the Illinois statutes route these filings to the County Clerk.

Certified Marriage Copies

Certified marriage copies for DuPage marriages come from the County Clerk's vital records desk. The official Application for Certification of Marriage charges $14 for the first certified copy and $2 for each additional certified copy of the same record ordered at the same time. Uncertified copies are only issued for genealogy records that are 75 years or older, at $1 per copy. Mail requests go to the County Clerk's P.O. Box in Wheaton, with a check or money order payable to the DuPage County Clerk in the exact amount.

The official marriage certification request form collects both spouses' names as they appear on their birth certificates, the marriage date and place, the requester's signature, the relationship to the person on the document, mailing address, phone, and email. Office-use fields hold cash, check, or credit details.

Marriage Form Fields at a Glance

The marriage certification form is the same PDF whether the request comes in by mail or in person. Reading through the form before filling it out saves a trip back to the office.

Note: A request with the wrong fee amount is returned. Always check the current marriage-copy fee on the County Clerk's site before mailing the form.

County Clerk vs. Circuit Clerk in DuPage

DuPage residents call the wrong clerk often enough that it is worth the side-by-side comparison. Both offices are elected, both are on the County Farm Road campus, and both have records the public can request. The work, however, splits cleanly between court files and county-government files.

Recorded deeds, mortgages, and liens are kept by the DuPage County Recorder's office, not the County Clerk and not the Circuit Clerk. See the DuPage public records page for the Recorder search and the property lookup tool.

Voter Registration and Election Records

The County Clerk runs voter registration, ballot mailing, and election-night returns for the unincorporated parts of DuPage and the precincts not covered by the City of Aurora Election Commission. Registered voters can check status, update an address, and find the polling place through the County Clerk's election page. Election results, candidate filings, and statement-of-candidacy paperwork live there as well.

Statements of economic interest filed by DuPage officials are searchable through the county portal. The public can use the search at ei.dupagecounty.gov/PublicSearch to pull a filer's annual disclosure form.

Statements of Economic Interest

Illinois law requires DuPage public officials, candidates, and many county employees to file an annual statement of economic interest. The County Clerk maintains the public archive of those statements. A statement lists sources of income, business interests, and other holdings that could create a conflict in public duties. Members of the public who want to review a specific filer's disclosure can use the County Clerk's portal to search by name or by office, then download the filing as a PDF.

Note: A statement that is missing from the search may have been filed under a different spelling; try a partial last name before assuming the filer is out of compliance with the disclosure rule.

How to Request DuPage County Clerk Records

Some County Clerk records are immediately downloadable from the public site, such as election results and statements of economic interest. Others, including marriage certified copies and certain historic vital records, need a written request and a fee paid to the office. Records that fall outside the standard menu can still be requested under the Illinois Freedom of Information Act through the county's FOIA officer.

1. Identify the record you need and check the County Clerk site to see if it is already published.
2. If a form exists, complete the form and pay the listed fee.
3. If no form exists, file a written FOIA request with the county and cite the record type and approximate date range.
4. The county must respond to a standard FOIA request within five business days, with a possible five-day extension under the statute.
5. If a denial is unclear, ask the Public Access Counselor at the Illinois Attorney General's office for review.

DuPage County Clerk Contact

The office accepts in-person visits during weekday business hours and mail requests at a P.O. Box in Wheaton. The office is closed on county holidays, so call before driving in for a same-day pickup.
