Back to all statesWisconsin public records are governed by the Wisconsin Public Records Law, which gives residents and the public the right to access government documents and records. From property ownership and court records to business filings and vital statistics, Wisconsin maintains extensive public databases across its 72 counties. Wisconsin operates the Consolidated Court Automation Programs (CCAP) portal — one of the most-used statewide case-search systems in the country — and county registers of deeds maintain land records. Whether you're conducting a background check, researching property history, or verifying business information, the resources below provide direct access to official Wisconsin public records.
Most Wisconsin public records can be accessed online through state agency portals like the Wisconsin Historical Society State Archives and the Wisconsin Vital Records Office, or through individual county clerk websites. For records not published online, agencies accept written requests under the Wisconsin Public Records Law — usually by mail or email — and must respond within the statutory deadline. Certified copies of vital records and court documents typically require a small fee and proof of identity.
