The Languages of Contract: A Comparative Law Perspective with a Focus on the CISG

In nowaday’s international trade, the contracting parties often come from a different linguistic background. As a consequence, the use of foreign languages in contractual relationships raises many issues the implications of which are often underestimated. They are thereby analysed in a comparative law perspective and with reference to the CISG experience. Before invoking consent defects and invalidity, a central role must be devoted to the interpretation of contract. In particular, we have to mention the following criteria: the principle of good faith/fairness, the binding effects of agreed usages and established practice, the promotion of uniform languages and neutral terminologies with specific reference to business contracts. In the first Section, I briefly introduce the debate on language risk in contractual communication, discussing the implications of language barriers for the validity of the contract. Then, I outline the problem of legal constraints protecting offical languages that may significantly impact the choice of a foreign idiom in contractual relationships.
