This article analyzes functionalist and normative assumptions about marriage, divorce, family, and gender in developmental models of family life cycle. An interdisciplinary review of the literature in family development, family sociology, and family therapy reveals how a deficit comparison model implicitly informs the discourse in the study of single‐parent families, women who are alone, and the adjustment of women and children to divorce. A feminist critique of family life cycle as the prevailing conceptual model in family development and therapy is presented, and postmodern definitions that deconstruct the concept of family are discussed. Future perspectives for research on family life and form are considered in terms of new action theory that considers divorce as a mode of resistance and change for women and families.
