Back to all statesWashington public records are governed by the Washington Public Records Act, which gives residents and the public the right to access government documents and records. From property ownership and court records to business filings and vital statistics, Washington maintains extensive public databases across its 39 counties. Washington courts publish case information through the Washington Courts portal, and county auditors maintain land and marriage records. Whether you're conducting a background check, researching property history, or verifying business information, the resources below provide direct access to official Washington public records.
Most Washington public records can be accessed online through state agency portals like the Washington State Archives and the Washington Center for Health Statistics, or through individual county clerk websites. For records not published online, agencies accept written requests under the Washington Public Records Act — usually by mail or email — and must respond within the statutory deadline. Certified copies of vital records and court documents typically require a small fee and proof of identity.

Washington State is home to some of the world's most valuable companies including Amazon, Microsoft, Boeing, and Starbucks, making its Secretary of State portal a frequently-searched resource for investors, attorneys, and lenders. The Washington Corporations Division maintains records for corporations, LLCs, limited partnerships, and other entity types. Washington requires annual reports to maintain good standing, and the portal is updated in real time. Washington has unique requirements for professional service companies — attorneys, physicians, accountants, and other licensed professionals must form Professional Service Corporations (PSCs) or Professional Limited Liability Companies (PLLCs) rather than standard entities. These appear in the SOS database with their entity type clearly labeled. For out-of-state entities doing business in Washington, foreign registration is required, and those entities also appear in the database. Washington's portal provides direct links to filed documents including formation certificates, annual reports, and amendments.
