The sociology of law, legal sociology, or law and society is often described as a sub-discipline of sociology or an interdisciplinary approach within legal studies. Some see sociology of law as belonging "necessarily" to the field of sociology, but others tend to consider it a field of research caught up between the disciplines of law and sociology. Still others regard it as neither a subdiscipline of sociology nor a branch of legal studies but as a field of research on its own right within the broader social science tradition. Accordingly, it may be described without reference to mainstream sociology as "the systematic, theoretically grounded, empirical study of law as a set of social practices or as an aspect or field of social experience". It has been seen as treating law and justice as fundamental institutions of the basic structure of society mediating "between political and economic interests, between culture and the normative order of society, establishing and maintaining interdependence, and constituting themselves as sources of consensus, coercion and social control".

Sociology is the scientific and systematic study of human society that focuses on society, human social behavior, patterns of social relationships, social interaction, and aspects of culture associated with everyday life. Regarded as a part of both the social sciences and humanities, sociology uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order and social change. Sociological subject matter ranges from micro-level analyses of individual interaction and agency to macro-level analyses of social systems and social structure. Applied sociological research may be applied directly to social policy and welfare, whereas theoretical approaches may focus on the understanding of social processes and phenomenological method.
