I can't be the only one who recognizes that making people in foreign countries, like say, Austria in Europe, have to file this is in King County Courts in Seattle seems a little fucking dubious. I say this as a Washington State resident. Because it's super easy for me to commute to Seattle to sue Valve... but it's not for everyone else.
I don't know what, if any, options King County Court offers for people from other countries filing suit to be able to do it remotely. I get the distinct feeling this is a "fuck you, show up on our turf or fuck off."
Looks like District Court might have remote-access options, but I'm not sure if you'll still have to retain a local lawyer. It says any state or federal courts, but I'm not sure if District court counts more as a city-level court than state-level.
