Wisconsin criminal records come from two main sources: the state criminal history repository (maintained by the state police or equivalent agency) and individual county court systems. These are separate databases that may show different information.
What this page covers: Wisconsin state-level criminal history searches, county court criminal case lookups, and sex offender registry searches. What it does not cover: Federal criminal cases (those require PACER) or arrest records that did not result in charges.
Where to start: For a broad criminal history check, start with the state repository. For specific case details (charges, dispositions, documents), go to the Clerk of Circuit Court in the county where the case was filed. For sex offenders, use the state sex offender registry.
Common mistake: A state criminal history search and a county court search are not the same thing. The state repository compiles conviction data from across the state. County courts have the actual case files with full detail. You may need both.

Frequently Asked Questions
Is there a free statewide criminal search in Wisconsin?▼

County-level court records can be searched at no cost through individual court websites.
How do I search Wisconsin court cases?▼
Wisconsin's court system is headed by the Wisconsin Supreme Court. Trial-court business is handled by the Circuit Court (each of 72 counties), Municipal Court. Many Wisconsin courts publish docket searches and case lookups online — see the Court Records tab above for direct links.
