If you intend to do business in other countries, then you most certainly will need some help with trade law.
Produced by the member law firms of Lexwork International (network of independent law firms), this Compendium provides trade law summaries for over 30 jurisdictions prepared by law firms located there. Includes most significant US trading partners.
This does not mean you don't need a good international lawyer. Every global SMB at some point needs one during rapid growth stage (or before if you're really smart about anticipating what's ahead). He or she becomes a part of your global "dream team."
Anyway, check out the Compendium here.
