Suing someone who lives in the same town as you is already a giant pain in the ass. Figuring out how to do it in another country?

Good luck not being screwed by your attorneys, for instance, or even knowing which type to call!

Every country has significant and meaningful differences in legal traditions, laws, procedures, etc.

For easy examples, try to figure out how to (actually) make a fraud claim against someone in England, France, Russia, and Thailand.
