Searching Boone County: what to expect
Boone County publishes some records directly — 3 local sources below — and leans on state systems for the rest. The county docket is online at boonecircuitclerk.us — one of the more useful local sources, since Illinois has no single statewide court search. Two local sources do most of the work — boonecountyil.gov for local vital-records requests, booneil.devnetwedge.com for parcel and property-tax data. One gap: recorded documents aren't published by the county itself. Use the Illinois recorded documents page for those.

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.

FACTSealing 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."
FACTOnly the official Illinois state repository has verified, current Boone County data. Free sites often have stale data.

MYTH"All county records older than 50 years are public."

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.
