Following a Consultation exercise conducted by the Lord Chancellor's Department, the U.K. Government has announced its intention to amend the Children Act 1989 so that the unmarried father who jointly registers the birth with the mother will acquire parental responsibility automatically. In this paper, I draw on the responses made to the L.C.D. Consultation, in order critically to evaluate the arguments for and against reform. A poverty of relevant empirical research makes it impossible to reach a properly informed view on (...) the positive or negative impacts of implementing the proposal. However, the principled arguments: that unmarried fathers and their children are subject to discrimination, or that it is unfair for men to pay child support, yet have no automatic rights with regard to their children, are ultimately unconvincing. I also attempt a more explicitly sociological exploration of the Consultation and reform process, focusing on what it can tell us about evolving social attitudes towards the statuses of `father' and `family' and how they should be valued and protected.
