Legal Pluralism in Nigeria is traceable to her colonial history, when the British colonizers through a system of indirect rule maintained the independence of the customary legal systems that existed in the various regions occupying the geographical location now known as Nigeria. To serve a supervisory role over the native legal systems, the English legal system was also introduced into the Nigerian legal system. Thus, even during the colonial period legal pluralism became permanently woven into the Nigerian legal system. In the post-colonial period, the scope was expanded to include not only the customary legal systems, but also some parts of the English legal system that were ratified, and also the new Nigerian Constitution. The coexistence of these legal systems raises the issue of conflict of laws. These conflicts of laws have effects on Nigerian institutions, but graver is its impact on the internal migrants. The objective of this study therefrom is an analysis of the implications of legal pluralism on the internal migrant in Nigeria, for the purpose of identifying the limitations it poses to development in a Democratic State of Law.Subsequently, reforms and recommendations are made based on this situation, opting for the strategy of integration of coexisting legal systems. To achieve this, a bibliographic study is undertaken in analyzing the effect of the conflict of laws on the internal migrant in the areas of Succession, Marriage, and Education. After establishing the existence of discrimination and unequal treatment and pointing out that they were limits to internal migration and national integration in the face of legal pluralism, recommendations from authors on the solutions to the problems arising from legal pluralism are analyzed giving their applicability to the current situation, discussing precisely the need for reforms to enable compliance with the constitutional provisions on national integration.
