SEARCH KING COUNTY SUPERIOR COURT →King County Jail Release Information
Release depends on the legal basis for release and whether any other warrants, holds or court orders remain.
Paying bail does not mean a person will walk out immediately. Jail staff must confirm the payment, check for other legal holds and complete the administrative release process.
King County specifically warns that cashier's checks and money orders used for bail require verification and may therefore delay release.
Use the Subject Lookup Tool to confirm whether someone remains in custody.
