This paper is an approach to the way in which the State takes shape in the margins of the Colombian nation. It also inquires about the way the law work in such spaces, in postpeace agreement contexts. It is based on the testimony of two men who were actors in the Colombian armed conflict. The information was collected under the methodological approach of Multi-Sited Ethnography. Our conclusion is that the so-called post-conflict is a stage where alternative legal orders emerge as embodiments of State institutions. This means that the margins are spaces where the State has not consolidated effective and stable forms of social regulation. This situation opens a space for the emergence of local actors who play a role as intermediaries and no formal personifications of the State. © 2021, Asociacion de Antropologos Iberoamericanos en Red.
