Insurance lawyers have been curiously uninterested in the legal aspects of the use of insurance in export sales. It is an area which shows several doubtful points and some difficulties. According to the law of international sales and commercial credits, the primary question is whether the insurance contracts and documents that are produced satisfy the requirements of the sales and the credit contracts. From the point of view of insurance law, the question is how the insurance arrangements can be made to fit those requirements. The purpose of this study is to review problems that may occur in insuring cargoes in export sales.
