This article aims to provide new epistemological and methodological tools to critical legal theory. It outlines in three steps how the conceptual and methodological framework, provided by consubstantiality, help better understand the role of positive law in the production and reproduction of social relations. To illustrate this approach, the text is based on the apparent contradictions in the situation of women in the field of housing. The situation of women in housing seems to be marked by contradictions. Some women, mainly female lone-parent families and unattached senior female are among the people who know the longer core housing needs. In contrast, the rise of “condo” seems beneficial to women and matches with some of their aspirations of freedom. To better understand this paradoxical phenomenon, we propose the use of consubstantial method, which allows cross-action analysis of social relations. This analysis will be applied to a specific object, the Civil Code of Québec.
