I'm thinking of writing a new kind of EULA for my software and Terms of Service for my art commissions and website. I'm not sure of which country a court interprets those legal documents. I live in Croatia, but the laws in Croatia about electronic goods and services are unknown to me and I have no money to afford a lawyer. I'm not sure if I should afford a lawyer in Croatia if maybe there's a united internet law of some kind where the EULAs and Terms of Services are interpretted.
Who interprets those? May I ask someone who's not in Croatia to write and interpret my EULAs and Terms of Services? Should I ask a free lawyer online? Of which country should that lawyer be?
