You've Got Indictments
Lam1969 writes "Reuters reports that South Korean prosecutors have started a program to start sending indictment notices via SMS. The program was started partly because of the high penetration of mobile phones among the South Korean population (75%, according to the article), and also because prosecutors want to save money by cutting back on paper mailings. One potential hitch in the program: You have to apply to the service in order to receive your indictment electronically."
For most court things, delivery in person is how it's done. That's the only real way to make sure the right person got it. For criminal complaints, generally you are served by the police, and they arrest you in the process. For civil complaints, you can hire the police to serve the papers (which isn't a bad idea since they keep records) or have someone else do it, but it can't be you.
For things like jury duty notices it's mail, but I don't believe it's certified, just normal mail.
