The past decades have seen significant changes in the way non heterosexual sexualities are regulated in European countries. In a moment of ongoing transitions, the interdisciplinary research presented focuses on aspects related to homosexuals rights and the way LGBT individuals deal and perceive the impact that the presence (or absence) of laws has on their intimate lives.The evolutions in family rights in European laws and the balance towards equal rights, whether you are homosexual or heterosexual, are first detailed with an analysis of typical sequences found in a legal survey.Demographic analyses enrich these aspects in dealing with registration and parenting. Statistical analyses of same-sex partnerships and same-sex marriages show frequencies of registration together with a focus on parenting linked to the partnership status.In the next chapters, same-sex families are specifically studied in their daily life in France, Iceland and Italy through qualitative data. It investigates from a legal point of view and from a social perspective, what is at stake in the changing life of homosexuals in the field of parenting, what brings to everyday life the support of the law and what its absence implies.The Postface opens towards the future of LGBT research.
