Herein I present a detailed description of a file of the first juvenile court created in Córdoba, Argentina, in 1957. This document, together with many others, should have been destroyed. But occasional reasons enabled it to escape its fate and be finally rescued. The aforementioned document resolves who would take care of a girl. In view of the material forms of the document an inquiry is made into the usual legal proceedings and the kind of family portraits constructed in that context, with the intention of reflecting on how was it possible for children who were kidnapped together with their parents, or who were born during their mothers’ captivity in detention centers of that dictatorship, to have been legally adopted, and now be missing for their families of origin. https://doi.org/10.22380/2539472X78
