King County People Search
King County people search tools let you look up public records tied to a person across Seattle and the rest of the county. You can search Superior Court case files, recorded deeds, parcel data, sheriff logs, and inmate info. The King County people search process pulls from several offices, since no single site holds it all. Start with a name or case number. Then move between the Clerk, Auditor, Assessor, and Sheriff. Each King County people search source adds a piece of the full picture for the person you are looking up.
King County People Search Basics
The Department of Judicial Administration runs the Superior Court case index. The King County people search starts there for most users. You can look up civil, criminal, family, and probate filings by party name. Basic case info is free. Certified copies cost $5 for the first page plus $1 per added page. The Clerk also fields walk-in requests at the courthouse at 516 3rd Avenue in Seattle. Call 206-296-9300 for help. More detail lives in the King County Superior Court case search portal.
The King County Recorder keeps deeds, liens, and marriage records. You can run a free name search on the Landmark Web index for docs filed since August 1, 1991. Older files go back to the 1850s but may need Archives help. Recording fees follow RCW 36.18.010. Deeds, mortgages, and liens all show up in the same index. That makes the Recorder a strong second stop for any people search in King County.
Note: Case record access is governed by GR 31 and the Washington Court Records Act under RCW 2.68, not the Public Records Act.
Search King County Court Records
King County Superior Court handles felonies, civil suits over $100,000, family law, and probate. The Clerk indexes every filing. You can search by party name or case number through the online portal. Docket entries, hearing dates, and case status all show up for free. Full document images may need a JIS-Link subscription at $30 per month, or a trip to the courthouse. The Clerk's Office customer service line is clerksofficecustomerservice@KingCounty.gov.
District Court covers misdemeanors, small claims, and traffic. It runs four divisions in Seattle, Issaquah, Federal Way, and SeaTac. Each handles local cases. A full King County people search often pulls from both Superior and District Court, since the two cover different case types.
Statewide coverage is also available. The Washington Courts public case search links many counties in one place. This lets you check if a person has cases filed elsewhere in the state. Use it side by side with the King County portal for a broader sweep.
Court data is public under RCW 42.56 and GR 31, with some exceptions. Sealed juvenile records, sealed adoption files, and certain protected financial data are not shown. Social Security numbers are redacted on public filings. Those rules apply to every King County people search request, whether online or in person.
King County Assessor Parcel Lookup
The King County Assessor's site is a key stop for any property-linked people search. The office lists owners, sale history, and values at kingcounty.gov/en/dept/assessor.
The page links to the Parcel Viewer and iMap tools for free use.
The Assessor's Office sits at 500 4th Avenue, Seattle, WA 98104. Call 206-296-7300 for help. The e-Real Property app lets you search by address, parcel number, or owner name. You get current and past assessed values, sales history, and tax district info. None of it costs anything to view. That makes it a handy front door for a King County people search when you know where someone owns property.
Tax payment details live with King County Treasury at 206-263-2890. The Treasury and Assessor pages are linked. The iMap tool shows parcel shapes, zoning, and environment data. For seniors and disabled owners, exemption records exist, though some info is kept private under state law.
Note: Assessor data is free to search, but confidential income and exemption details are exempt from public disclosure.
Sheriff and Law Enforcement Records
The Sheriff's Office covers unincorporated King County and twelve contract cities. It also polices transit, the airport, and the Muckleshoot Tribe. Arrest logs and incident reports come from the Sheriff's Records Unit. Some items stay closed during active cases under RCW 42.56.240.
Requests go through the King County Public Records Program. The county charges $0.15 per paper page, $0.25 for color, $0.10 per scanned page for electronic records, and $0.10 per gigabyte for transmission, under RCW 42.56.120. In-person inspection is free. Fee waivers may apply when the release benefits the public. Agencies must reply within five business days under RCW 42.56.520.
Learn more at the King County Sheriff's Office site.
The page lists records, jail, and patrol info.
Jail bookings and the inmate lookup tool round out the criminal side of a King County people search. You can find out if someone is in custody, along with charges and booking date. This part is public. Medical and mental health data on inmates is not.
Public Records Act Requests
Anyone can file a request under the Washington Public Records Act. You do not need to be a state resident. You do not have to give a reason. Requestors can stay anonymous for most record types. Submit a King County people search request through the county's central portal, by email, by mail, or in person.
The request should clearly name the records wanted. A vague ask can slow the process. Provide dates, names, or case numbers when you can. The public records officer will confirm within five business days and give an estimate if the job will take longer.
Older files live at the King County Archives at 1215 E Fir Street. Call 206-477-6446 for an appointment. The Archives keeps Superior Court files, prosecuting attorney records, and historic property records going back to the 1850s. Staff can point you to other places if they do not hold the file you need.
Note: Fee waivers may apply if the records primarily benefit the general public under King County's public records policy.
Cities in King County
King County covers Seattle, Bellevue, Kent, Renton, and many other cities. Municipal courts handle traffic and city code cases. Seattle Municipal Court, Bellevue Municipal Court, and Kent Municipal Court all keep their own indexes. A full people search may need to cross-check those for low-level cases.
Each of these cities has its own people search page with local detail.
