DuPage County Clerk Records: Birth, Death, Marriage, and Civil Union Certificates

The DuPage County Clerk provides certified copies of DuPage County vital records. These include birth certificates for people born in DuPage County, death certificates for deaths that occurred in DuPage County, and marriage or civil union certificates for events recorded in DuPage County.

Vital records are not ordinary public records. Illinois law limits who can receive certain certified copies, so the Clerk may require proof of identity, proof of relationship, proof of legal interest, guardianship paperwork, or other supporting documents.

Birth certificates For a person born in DuPage County. Eligible requesters commonly include the person named on the record if at least 18, a listed parent, legal guardian, legal representative, or authorized agent.
Death certificates For a death that occurred in DuPage County. The requester generally needs a personal or property-right interest or legal authority to receive the record.
Marriage certificates For proof of a DuPage County marriage record. Certified copies are commonly used for name change, benefits, insurance, immigration, or agency proof.
Civil union certificates For DuPage County civil union records. Confirm the current form and fee before mailing your request.

Helpful local detail: the County Clerk is the right starting point for certified DuPage County birth, death, marriage, and civil union records, but divorce case records are court records. For divorce case filings, orders, or court copies, use the DuPage County Circuit Court Clerk instead.

DuPage County Clerk Forms: What to Download Before You Visit or Mail a Request

The safest way to avoid delays is to use the current form from the Clerk’s website. Older forms may still appear online, but the official DuPage County page should be treated as the source for the newest version.

Birth certificate request Requires the person’s name at birth, date and place of birth, parent/co-parent names, requester details, relationship, signature, ID, and payment.

Marriage Licenses, Civil Union Licenses, and Marriage Certificates in DuPage County

The DuPage County Clerk issues marriage and civil union licenses and provides certified copies of DuPage County marriage and civil union records. The license process is different from requesting a copy of an already-recorded marriage certificate.

For a new marriage license, both parties should expect to appear together and present identification after completing any required online application steps. For a certified copy of an existing marriage record, use the Clerk’s certificate request process.

New marriage license Use when you are planning to get married and need a license issued before the ceremony.
Marriage certificate copy Use when the marriage already happened and you need certified proof for an agency, name change, benefits, insurance, or records.
Civil union service Use the Clerk’s license and certificate pages for civil union application and certified-copy rules.
Genealogy note Some older marriage records may be issued as genealogy copies only and are not certified legal copies.

Assumed Business Name, Notary, and Local License Services

The DuPage County Clerk accepts assumed business name filings for certain businesses operating under a name other than the owner’s legal name. This is commonly called a DBA or assumed name filing.

The County Clerk page also lists several local licenses and registrations, including marriage and civil union licenses, liquor licenses for unincorporated DuPage County, raffle licenses for unincorporated DuPage County, tobacco licenses for unincorporated DuPage County, amusement device registration, and notary-related services.

Assumed business name For certain sole proprietors or partnerships using a business name that is not simply the owner’s real name.
Publication step The assumed name form states that after filing, the Clerk gives instructions for legal publication required by law.
Unincorporated county licenses Liquor, raffle, tobacco, and amusement-device items may apply only in unincorporated DuPage County.

Property Tax, Tax Redemptions, and County Clerk Administrative Duties

The DuPage County Clerk also has county-government duties beyond records. The Clerk acts as Clerk of the DuPage County Board, Secretary of the Emergency Telephone System Board, and Secretary of the Liquor Control Commission.

In the taxation process, the Clerk’s office helps compile the list of DuPage County parcels for tax assessment, calculates the amount of tax for each parcel, and certifies those amounts to the Treasurer’s Office for collection. Tax payments themselves are generally handled through the DuPage County Treasurer.

Property tax lookup Use the County property tax lookup when you need parcel tax history, tax year details, or tax bill information.
Tax redemption Use the Clerk’s tax redemption resources when a property tax sale/redemption issue applies.
Treasurer routing Use the Treasurer for many payment and collection questions.
Assessment routing Use the Supervisor of Assessments for many property assessment, exemption, and appeal questions.
