This paper presents a reflection about the implementation of Informed Consent (IC) in qualitative research, based on the experiences of a women researchers group from Facultad de Psicologia de la Universidad de la Reptblica (Uruguay). In a first instance, a brief historical description is performed, regarding the origins of Ethics Committees and IC in general and in Facultad de Psicologia de la UdelaR in particular. Then, an ethics and Informed Consent instrumentation analysis is elaborated, as a reflexive and dialogic process beyond the formal aspects institutionally established, and it's particularities in qualitative research from a Community Social Psychology approach. Through the narration of particular situations related to research project developed by members of the group, we reflect on: a) the role of institutions during the implementation of IC in people with institutionalization process. b) anonymity and co authorship possibilities. IC's implementation is not an innocuous process, thus the necessity of exploring the meanings that these procedures carry, their incidence on the relationships that are established within research process and its link with research ethics. In the concluding section, the need of institutional devices to promote mechanisms for reflexive vigilance is presented, in order to avoid the bureaucratization of ethics in research, as well as the importance of flexibility and creativity in community consent
