Abstract
Current law and social policy in the various UK legal systems privilege the conjugal couple, biological and filial relationships. Friendship remains on the margins of regulatory recognition. Yet friendship is of growing significance in contemporary social relationships. This is particularly so for older people, especially older lesbian, gay and bisexual people. This paper explores the place of friendship in key areas of law and social policy relating to older age: pensions, benefits and inheritance; medical decision making; mental health and mental capacity legislation; and social care policy. The extent to which contemporary law is keeping up with changing relationship forms will be considered, together with its implications for equality in later life.
