About King County Criminal History

King County criminal records are split among courts, the Sheriff's Office, detention officials, and Washington agencies. Seattle is the county seat and the largest records hub, but the correct source still depends on who created the file. King County Criminal History is a private reference resource built to make those official paths easier to distinguish. It points readers toward court case systems, records counters, public-disclosure channels, the Washington State Patrol, the Washington State Department of Corrections, and the Washington Sex Offender Public Registry.

Why We Built This Site

Public access in Washington does not mean every record sits in one database. King County Superior Court uses KC Script, District Court has its own case-access portal, and municipal matters remain with the city court that heard them. The King County Sheriff's Office handles its reports through the Public Disclosure Unit, while detention records belong to the Department of Adult and Juvenile Detention. Washington State Patrol compiles qualifying statewide criminal-history information in WASIS and provides public name checks through WATCH.

The aim is practical: separate those systems, explain what each record can show, and preserve the local details that affect a request. That includes the difference between a cause number and a Book of Arrest number, the limits of a public name match, and the need to obtain a certified record from its official custodian.

What You Will Find Here

Coverage stays focused on official King County and Washington access routes.

  • Record guides: how criminal court case records are found and read in King County
  • Official checks: how WATCH name searches and WSP fingerprint-based self-review differ
  • Agency contacts: where to reach court clerks, KCSO disclosure staff, detention records staff, and state systems
  • Record remedies: how Washington distinguishes vacation, court sealing, and deletion of eligible nonconviction data

What We Cannot Do

King County Criminal History is privately operated. It is not part of King County, the State of Washington, any court, or any law-enforcement agency. Those limits are firm:

  • We cannot retrieve an official record or perform an official criminal-history check
  • We cannot submit a public-records request or court filing for a visitor
  • We cannot issue certified court papers, WSP records, or sheriff reports
  • We cannot correct, seal, vacate, or delete a government record
  • We cannot offer legal advice about a charge, case, warrant, or remedy

Only the court or agency that maintains a King County record can issue an official copy and confirm its current status.

Search Partners

Some pages contain search boxes operated by outside providers. Those services control their prices, terms, data practices, and results. A paid signup reached through one of those tools may generate a referral fee that supports this resource. King County Criminal History does not control a partner's records or guarantee a match, and partner results do not replace records from the originating office.
