Why is This Book Relevant to You? When enterprises in different countries enter into an agreement with each other, there is always the question of governing law. This book is about choosing the UNIDROIT Principles! This solution is so good, and so comprehensible to everyone, that you do not have to start with suggesting your own country´s law, thereby starting the inevitable discussion. You can go directly to the best and most balanced solution. These principles are the common denominator for all our countries´ law, and they can be learned in some hours. Everyone will understand them. This book can be read without the Principles at hand, but the best result is of course achieved when you can immediately consult them. Therefore, the Principles are reproduced in this book with the kind consent of UNIDROIT.
