Matriliny in South India is often considered as having declined in the course of modernization. Recent studies, however, highlight the social construction of matriliny by modern legal discourse. As an alternative to these perspectives, this article presents a fresh viewpoint from which to analyze the reflexive relationship between modern law and local practice. In this article, I investigate the modern judicature's evolving interpretation and (re)construction of matriliny in colonial and postcolonial South Kanara. I also examine the practices of the local people who sustain and revitalize their own sense of matriliny through ritual practice while they cope with the new legislation on matriliny. Analyzing the legal discourse as well as popular practice, I elucidate the reflexive imagination involved in the discourse/practice of both the modern judicature and the people, which creates and recreates the gendered, legalized, and ritualized reality of matriliny in South Kanara.
