This article examines the Brexit-driven remaking of some EU families into mixed-status families. Drawing on original research conducted in 2021–2022 with British, EU/EEA and non-EU/EEA citizens living in the UK or the EU/EEA, it shows how families whose members have previously enjoyed equal rights to freedom of movement across the EU/EEA variously negotiate the consequences of Brexit on their lives. Central to our analysis is the interplay between hardening borders and the stickiness of family relations, and its effects on families’ migration and settlement projects. The article brings to the fore these emerging entanglements offering a much-needed relational analysis of the impact of Brexit on the directly affected populations, while contributing more widely to expanding the existing scholarship on mixed-status families, by attending to the peculiar ways in which families whose members previously enjoyed equal status under EU law have experienced their transformation into subjects with unequal rights.
