Customary law refers to the unwritten laws and customs that have been developed and practiced by a particular community or group of people over a long period of time. It is based on the traditions, beliefs, and practices of a particular society and is often passed down from generation to generation through oral tradition. Customary law can cover a wide range of areas, including property rights, marriage and family relations, inheritance, and dispute resolution. In many countries, customary law coexists with formal legal systems and is recognized and enforced by the state.
