Economic and legal reforms have triggered waves of conflict over property rights and access to urban land in Vietnam. In this article I develop four epistemic case studies to explore the main precepts and practices that courts must negotiate to extend their authority over land disputes. Courts face a dilemma: Do they apply state laws that disregard community regulatory practices and risk losing social relevance, or apply community notions of situational justice that undermine rule formalism? I conclude that reforms designed to increase rule formalism in the courts may have the unintended consequence of reducing the capacity for judges to find lasting solutions to land disputes.
