This lesson is second in a series that takes a look at formation of agreements governed by the U.N. Convention on the International Sale of Goods (CISG). The CISG provides a uniform set of rules for international sales contracts where the parties are located in different signatory countries. There are 11 separate provisions on contract formation under the CISG. This lesson sets out the basic requisites for determining whether an offer exists, when it is accepted and how to address a battle of the forms if the CISG applies. The general attributes of domestic contracts and other CISG contracts are covered in other lessons.
