Washington background check resources are easy to come by because this is an open records state, meaning most personal files and records are considered to be in the public domain.
Personal records such as marriage, divorce, birth or death certificates can be ordered from the Department of Health for $20 each (which is non-refundable). You can drop off the forms in Tumwater or send them to the office by mail if you don't mind waiting a month for results.
Similar regulations apply to criminal history files. The Washington Access to Criminal History (WATCH) system allows you to make online requests as long as you have a credit card to pay the $10 search fee. You can also get printable forms if you prefer to request records through the mail. These searches will provide you with conviction information and recent arrest details.
