In recent debates about the form and function of the family much atten
tion has focused on the deleterious consequences deemed to attach to f
ather-absence (for example, in relation to issues around child support
and the criminality of male youth). At the heart of these debates, th
ough it is seldom addressed as such, is the question of what being a '
father' actually involves. This article seeks to relate changes in leg
al conceptions of fatherhood to wider shifts in the historical constru
ction of heterosexuality and, in particular, to the emergence of a dis
tinct discourse of a 'respectable' familial masculinity. In contrast t
o ideas of 'undomesticated' and 'dangerous' masculinities, it is argue
d that the idea of the family man has come to signify in law a range o
f (frequently contradictory) ideas about heterosexual masculinity. The
law continues to valorize a particular male heterosexual subject posi
tion, though importantly, the mechanisms by which it does so have chan
ged from the late nineteenth century to the present day. Through refer
ence to this reconstruction of paternal masculinity in law, this artic
le questions the idea that we are now witnessing a form of contemporar
y 'crisis' in masculinity and the family.
