Washington offers strong online access: the Secretary of State handles business filings, the Courts site provides statewide case search, VoteWA covers elections, and the Department of Revenue runs unclaimed property. Counties like King publish robust free property records.
Washington has one of the strongest open-records statutes in the country and the case law to back it. The Public Records Act, RCW 42.56, originated in a 1972 citizen initiative, requires agencies to respond within five business days, and carries mandatory penalties for wrongful withholding that courts have applied aggressively. There is no residency or purpose requirement, agencies must provide the fullest assistance to requesters, and exemptions are construed narrowly — the Attorney General maintains a model rules and open government resource library that agencies are expected to follow.
Courts are searchable in one place. The Administrative Office of the Courts publishes a free statewide case search covering superior, district, and municipal courts, so a single name query spans every level of trial court — something even large states rarely offer. What the free index gives you is the case number, filing date, court, and parties; full docket detail and documents come through the county clerk or the paid JIS-Link service. That two-tier structure is the pattern we describe on the court records hub.
Business filings run through the Secretary of State's Corporations and Charities Filing System, free to search with filing images and annual report history, while the Department of Revenue's Business Lookup ties an entity to its UBI number, tax registration status, and endorsements. Because Washington has no personal or corporate income tax and runs on a business and occupation tax instead, DOR's public business lookup carries operating-status information that in most states would be confidential — a genuinely useful cross-check alongside the entity record on the business records hub.
Property records are held by 39 counties, with the assessor handling valuation and the auditor handling recording. Washington is a disclosure state through the real estate excise tax affidavit, which records the sale price for every transfer and is a public document — assessors publish sales histories built directly from those affidavits. King, Pierce, and Snohomish counties offer especially detailed free parcel reports including building characteristics, permit history, and levy breakdowns. Unclaimed property runs through the Department of Revenue, and the State Patrol's WATCH system lets anyone run a name-based conviction search online for a small fee.

It shows the index-level data: case number, court, filing date, case type, and party names. Charges, hearings, and documents come from the county clerk's own system or the subscription JIS-Link service. Use the statewide search to find where a case exists, then go to that court for the file.
Check two places. The Secretary of State's CCFS confirms the entity is registered and current on annual reports; the Department of Revenue Business Lookup shows the UBI, tax registration status, and any endorsements, which reflects whether the business is actually transacting.
Yes. A real estate excise tax affidavit stating the selling price is filed with the county treasurer on every transfer and is public, and county assessors publish sales histories drawn from those affidavits. Certain exempt transfers, such as gifts or transfers into a trust, show no price.
Within five business days an agency must provide the record, acknowledge the request with a reasonable time estimate, ask for a clarification, or deny it in writing with the specific exemption cited. Silence is a violation and can expose the agency to daily penalties in a subsequent court action.
