This article builds on three of Keebet von Benda-Beckmann’s core concepts, namely, legal pluralism, social security and relational social theory, to reflect on the place of law in lived migration orders, both in the global north and in the global south. To do this, we build on three empirical case studies from our respective fieldsites in Germany, Belgium and the DRC. These cases illustrate how ‘thinking with Keebet’s work’ not only offers useful ‘sensitizing concepts’ for the empirical study of migration law and migration studies more broadly, but also provides a much-needed conceptual vocabulary to speak to and intervene in current debates in more doctrinal legal scholarship on global migration law. With this double aim in mind, we first build on a legal pluralism perspective to show how migration governance can be better understood through the prism of ‘lived migration orders’. We then suggest rethinking state sovereignty, citizenship, and individual human rights in light of historical and newly emerging relational configurations. Finally, we suggest a new avenue for reconceptualizing migration governance beyond rights-based categorizations of migrants by paying more nuanced analytical attention to situations of uncertainty and how they contribute to social (in-)security.
