Law is essential to the establishment and maintenance of social order in our society. But we also need to recognise that there are other ways to establish order outside the legal system as it now exists. Order is not only based on the law; it also encompasses issues of a broader moral and political nature, even in our society. An explanation of the form of order in general is not the focus of this work. More specifically, it focuses on outlining and clarifying the essential institutional components of the specific kind of order known as legal order. Business and commercial activity are ultimately controlled and regulated by law, and they occur within a legal framework. A challenge that faces anyone studying business activity is that business enterprise occurs in a broad and general legal environment; however, the student must possess more than a cursory understanding of the legal procedures and regulations that affect business activity. This book specifically addresses this issue. This book’s main goal is to provide students with a companion that is simple to teach while covering the necessary curriculum. Our aim has been to include the most recent curriculum updates for undergraduate, graduate, and postgraduate programmes offered by different centres and state universities. The Contract Act, the Sale of Goods Act, and the Negotiable Instrument Act are among the many acts that are addressed in this book.
