The 4-Step Boone County Records Pathway
1
Step 1 — Start at the Boone County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Boone County clerk's office is the first stop.
2
Step 2 — Use the Illinois statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the Illinois state level — not by the county.
3
Step 3 — Federal sources for federal records
Federal court cases (PACER), federal tax liens (IRS), military records (NPRC), and immigration data (ICE) are all federal — not held by the county.
4
Step 4 — Cross-check before relying on data
Most county portals lag 24-48 hours behind the courthouse. For time-sensitive verification, call the clerk directly.
Five Things People Get Wrong About Boone County Records
❌ Myth: "Boone County maintains all criminal records."
✓ Truth: False. Criminal records for Boone County are held by the Illinois state repository, NOT the county. The county sheriff has only the local arrest log.
❌ Myth: "Records sealed in Boone County are gone everywhere."
✓ Truth: False. Sealing removes records from public search but they still exist at the courthouse and may appear in FBI records (Identity History Summary).
❌ Myth: "Free 'instant background' sites have Boone County data."
✓ Truth: False. Only the official Illinois state repository has verified, current Boone County data. Free sites often have stale data.
❌ Myth: "The Boone County assessor's value is what I'll sell my home for."
✓ Truth: False. The Boone County assessor's value is for property tax purposes only — usually below market value.
❌ Myth: "All county records older than 50 years are public."
✓ Truth: Partially false. Public-records rules vary by record type AND state. Court records and deeds are usually older-public; vital records remain restricted longer (often 75-125 years).

Frequently Asked Questions
How do I look up court cases in Boone County?
Boone County court cases are filed with the Circuit Clerk. Search the State of Illinois Office of the Illinois Courts portal: https://www.illinoiscourts.gov/. For federal matters, see PACER.
Does an arrest show up on a background check before conviction in Illinois?
Yes — in Illinois, an arrest can appear on a name-based background check from the moment of booking, even before any court ruling. Whether it appears on an employment screening depends on the type of check (name-based vs. fingerprint-based) and how recent the arrest is.
How long does an arrest stay on my record in Illinois if I wasn't convicted?
In Illinois, an arrest stays on your record indefinitely unless you petition the court to seal or expunge it, even if charges were dropped or you were found not guilty. Illinois's rules for clearing non-conviction records are stricter than for convictions — start with the Illinois State Police.
Are Illinois criminal records public?
Mostly yes. Illinois's public-records law makes adult arrests, court filings, and conviction histories accessible to anyone unless a specific statutory exemption applies. Juvenile cases and sealed records are generally excluded by statute.
