This article aims to reflect on the judicial bureaucracy from a point of view focused on the interaction between people and objects. In other words, we aim to contribute to the understanding of the configuration of the State from the different links between objects (files) and people (officers and citizens). For this purpose, the article is divided in three sections. The first section makes a bibliographical balance of the way (form) in which how courts and files have been researched in and outside the country. Then we have the ethnographic description of the office, explaining the positions and functions of the employees, and the cycle that files go through in them. Finally, we carry out a theoretical reflection on the materiality of justice based on ethnographical data.
