This article examines the history of the Chilean Legal Aid Service (Servicio de Asistencia Judicial) from the 1920s until the 1960s. It argues that with the emergence of the "social question"-the concern for improving the lower classes' working and living conditions to promote the nation's modernization and prevent political radicalizationthe Chilean legal profession committed to legal aid reform to escape a professional identity crisis. Legal aid allowed lawyers to claim they had a new "social function" advocating on behalf of the poor. However, within legal aid offices, lawyers interacted with female social workers who acted as gatekeepers, mediators, and translators between the lawyers and the poor. This gendered professional complementarity in legal aid offices helped lawyers to put limits on their new "social function": it allowed them to maintain legal aid as a part-time activity that did not challenge the structure of the legal system as a whole.
