Joliet Vital Records for Genealogy
Joliet vital records are managed by the Will County Clerk. The office is at 302 N. Chicago Street, Joliet, IL 60432. Call (815) 740-4615 or email vitalrecords@willcounty.gov. Will County has birth and death records from December 1, 1877 and marriage records all the way back to 1836. That gives Joliet genealogy researchers a deep set of records to work with.
Fees for vital records are $14 for birth, death, or marriage copies. Certification costs $1 per record. The county warns that VitalChek is not recommended for genealogy requests. Older records may not be in the VitalChek system, and the fees can add up fast for records that might not even exist in their database. You are better off contacting the clerk directly for Joliet genealogy records.
Under the Vital Records Act (410 ILCS 535), birth records open for genealogy access after 75 years. Death records open after 20 years. Marriage records open after 50 years. These are uncertified copies stamped for genealogy use only. For Joliet researchers, that means birth records from 1951 and earlier are now available for genealogy purposes.
Joliet Library Local History Room
The Joliet Public Library runs a Local History Room that is one of the best genealogy resources in Will County. The room has newspapers on microfilm starting from 1846. That is more than 175 years of local news coverage. For Joliet genealogy, old newspapers can turn up obituaries, wedding notices, court reports, and mentions of family events that you cannot find anywhere else.
The library also keeps city directories from 1875 on. Like other directory collections across the state, these list residents by name, address, and work. Year after year, you can track where a Joliet ancestor lived and what they did. The obituary indexes cover two time periods: 1915 to 1918 and 1976 to 2012. That second range alone covers 36 years of deaths in the Joliet area.
Joliet Public Library is a FamilySearch Affiliate Library. That means you can access FamilySearch films and digital records through the library's system. Ancestry Library Edition is also available free in the library. Both tools open up millions of records beyond what the county clerk holds. Staff in the Local History Room can point you to the right databases if you are not sure where to start.
Joliet Court and Land Records
Will County court records are searchable through the 12th Judicial Circuit portal. This covers the circuit court that serves Joliet and all of Will County. Court files can include probate records, divorce filings, and naturalization papers. Probate records are especially useful for genealogy. They often list heirs, property, and family relationships in detail.
The Will County Recorder of Deeds is at 158 N. Scott Street in Joliet. Their online search system covers all recorded documents going back to 1836. That is one of the longest digital record spans in the state. Land deeds, mortgages, and plat maps can all help you place a Joliet ancestor at a specific address in a specific year. For genealogy, that kind of location data is hard to beat.
Note: Will County land records go back to 1836, giving Joliet researchers one of the deepest online property record collections in Illinois.

These can turn up Joliet ancestors without a fee or a trip.
The state archives also maintains a public domain land sale database. Early Will County settlers who bought land from the government may appear in this index. All state archives databases are free.
