Democratic family, as a new phenomenon in Iran, is based on some fundamental principles such as liberty, equality, rule of law, and tolerance. In this article, some of the important aspects of a democratic family in Iran will be explained and evaluated by applying conceptual analysis and critical evaluation. The family, which is characterized by middle class, rights, population and urbanization, marriage and divorce, violence, and nuclear family, lead to reasonable decision-making through dialogue and cooperation. The patriarchal mode of management in Iranian family has gradually changed into a collective decision-making, in which, the role of boys and girls are significant. These characteristics indicate that Iranian democratic family is a transitional process of social and political development in Iran.
