Feminists have noted the injustice of the institution of marriage and the asymmetric power dynamics within gender-structured marriages. Recently, feminists have found an unexpected supporter of this struggle against marriage in some liberal political theorists. I argue that this new wave of interest in the wrongness of marriage within liberalism reveals shortcomings from a feminist perspective. While some liberals fail to realise that instead of being disestablished, the institution of marriage should be radically reformed, others do not recognise that such a reform should be theorised by starting from our non-idealised conditions of gender inequality and from an analysis of how the institution of marriage intersects with other spheres of gender injustice. This article provides recommendations for the radical reform of marriage by following some methodological premises of feminist theory. To illustrate how the reform of marriage should be theorised, it focuses on the intersection between the sphere of gender injustice represented by immigration and that of marriage.
