Our goal is to make the critique of the family concept presented in the guidelines of the National Policy for Social Assistance-PNAS, approved in 2004, and still until today. Considered as an advance in the complex relationship of concession-conquest, PNAS, through the implementation of the Social Assistance Unique System (SUAS), tries to organize assistance such as security right, outstanding the matricialidade family member on the centrality of this policy. Focusing on the family brings aims proposing full protection from the state, which cares for individuals, taking into account the and familiar sphere, to put an end to the culture of the fragmentation in the service of demands through public policies. In order to accomplish that goal, public policy of assistance should strive for a protection that ensures survival security (of income and autonomy); of protectio; and conviviality or family experience (PNAS 2004). However, a denial to the materialization of constitutional rights, through the deployment of SUAS guidelines, PNAS rescues the conservative principles and values for the understanding of the family. In this manner, it becomes an instrument of accountability for poor families, seeking, through the fault of individuals, the solutions of the refractions of the social question, that are resized as individual and family problems.
