In this chapter, the question of the place and role of the father in the family will be treated in a systemic perspective. The father’s place depends on several factors like the father’s desire to be involved, the quality of co-parenting relationship, the quality of marital relationship, a possible maternal gatekeeping, social support like paternal leave, the family composition, and so on. Keeping in mind the best interest of children, researches will be presented and will serve as a base for discussion.
