This page routes Lyon County criminal record questions to the official office that holds each file. Sheriff and jail records come from the Law Enforcement Center in Rock Rapids. Court cases and certified copies come from the Clerk of District Court. Statewide criminal-history checks come from Iowa DCI. This private site does not receive or fulfill government record requests.

This Is Not a Government Office. This private reference site cannot retrieve an official record, correct or remove an entry, process a background check, or accept an expungement filing. Contact the responsible government custodian.

The Sheriff does not publish a separately named records division, local request form, fixed copy fee, or guaranteed turnaround. Send a focused Iowa Code chapter 22 request to the Sheriff and ask for a cost estimate. The Clerk handles older cases, court inspection, copy questions, and certification. Court staff can explain access steps but cannot give legal advice.
