This contribution to the special issue addresses the "what, how, what to be wary of, and why" questions about socio-legal approaches to researching property law. As will become clear, it is not possible to talk about "the" socio-legal approach; this article starts with these definitional difficulties and then discusses the range of research which can be labelled as socio-legal. Following an overview of the challenges faced by the socio-legal researcher, the article concludes by assessing the unique perspective provided by this research approach.
Definitional difficulties and developmentIt seems widely accepted that there is no agreed definition of the socio-legal research approach. 1 Indeed, the meanings of both the 'socio' and the 'legal' components of this hyphenated composite are the subject of continuing debates.2 These definitional difficulties may be partly due to the different starting points and divergent histories of socio-legal research in the US, the UK, Europe, and elsewhere.In North America, Roscoe Pound set socio-legal researchers in the early twentieth century the task of investigating the measurable and observable effects of law, using social science empirical methods.
