In this article, I examine the legal position of those who perform caregiving work within the context of a cohabiting relationship through a novel relational vulnerability lens. I argue that the state, through privatising and devaluing caregiving labour, situates carers within an unequal and imbalanced relational framework, exposing them economic, emotional, and spatial harms. Unlike universal vulnerability, which is inherent and unavoidable, relational vulnerability can be avoided and reduced if the state were to acknowledge that humans are embodied and relational (...) rather than self-sufficient and rational. Law’s treatment of cohabiting carers reflects the state’s broader tendency to value economic self-sufficiency, while confining caregiving to the private family. I argue that the state has a duty to respond directly to relational vulnerability and should aim to make cohabiting carers resilient. Resilience must involve the provision of material resources but should also have a normative commitment to achieving autonomy and equality for those marginalised by law and state policies. (shrink)
