Any lawyer involved in cross-border transactions or disputes should be aware of the United Nations Convention on Contracts for the International Sale of Goods (the CISG). The CISG (sometimes referred to as the Vienna Convention) is a treaty that governs international contracts for the sale of goods between parties doing business in those countries that have ratified the treaty. It applies by default to any such contracts, and has been adopted by 94 countries, including the U.S., most of Europe, and most of Asia (though notably not the U.K., India, and Taiwan). That makes it one of the most widely adopted international treaties, and it covers approximately two-thirds of international trade contracts today.
