The aim of this paper is to analyse approaches to issues of risk, responsibility and representations of violence in women social workers' conversations with alleged or confirmed violent fathers. The study adds to a growing body of research on agencies' handling of intimate partner violence (IPV) in the context of separation. Empirically, the study draws from 12 structured, audio recorded and transcribed interviews with support-seeking and divorced fathers, from five municipalities in Sweden, conducted as part of a cooperation project in which a risk-detection method (Family Law Detection Of Overall Risk Screen [FL-DOORS]) was also tested. The results suggest a tension between different professional tasks. To validate information on IPV, detect risk and enhance a child perspective competes with other professional projects, most obviously with promoting cooperation between parents. The study confirms previous research, which demonstrates unique challenges facing women social workers and counsellors when working with men as perpetrators. In conclusion, the paper concurs with the call for a focus on responsibility and on safe parenting in professional conversations with allegedly or confirmed abusive fathers.
