This is actually an amazing advance. The offical website of the Washington state court system now makes basic Superior Court docket information available online for all counties. There are limitations, of course: basically no sealed file information and no pre-1980 cases. Nonetheless, this is a great leap forward in the information readily available over the Internet to those with an interest in cases in Washington state.
Unfortunately, I can't jettison Courtlink and its expensive searches quite yet, because there's only limited information about district and municipal court available at the moment. The prudent family law practitioner is well advised to run district and municipal court searches on every opposing party in every case. In fact, I can directly attribute a flat-out victory in one of my cases to the material I was able to gather from district court docket sheets throughout the county.
Moreover, the careful family law practitioner is well-advised to run the same searches on her clients. All of them.
