In the recent past, comparative law has gained popularity due to democratization, internationalism, as well as economic globalization. The comparative law deals with the similarities and differences between the laws of different countries. It involves the study of several legal systems that exist in the world, such as the civil law, Canon law, Islamic law, Chinese law, common law, socialist law, Jewish law, and Hindu law. The comparative law includes the analysis and description of international legal structures, even where clear comparisons are missing. Comparative law has been divided into other fields such as the comparative constitutional law, comparative civil law, comparative criminal law, comparative administrative law, and comparative commercial law.
Comparative law serves three major purposes which include perfecting the legal systems being used, unification of legal systems, and acquiring deeper knowledge of the legal structures in effect. Regardless of the differences between comparative law and other legal fields, the other legal fields borrow quite a lot from comparative law. For instance, knowledge in comparative law can be used to assist international legal institutions in evaluating the laws of other countries concerning their treaty obligations. The comparative law can also be applied in private international law especially in conflict analysis.
