This paper reframes debates about gender equality in the legal professions by interrogating the practices of men and interconnections between fatherhood, gender and parenting within the specific context of large corporate law firms. Drawing on interviews with male lawyer-fathers, it argues that closer exploration of fatherhood reveals much about the gendered dynamics of identity formation as a legal professional in this sector. A set of ideas about fatherhood, the paper suggests, shape how men's work can define a distinctive gender identity as a ‘family man’ and good lawyer. Political-economic and cultural shifts around fatherhood, however, are reconfiguring and adapting gender relations in law in a number of contradictory ways with implications for understanding the place of men in relation to gender-equality agendas. Ideas about fatherhood, family, work and career, I argue, are mobilised and enmeshed within the reproduction of distinctive law-firm cultures and gendered ideas of organisational commitment. What, in short, might it mean to be both a ‘good father’ and a ‘good lawyer’?
