The bioethics bill reflects a paradigm shift in filiation. Indeed, the bill provides for the lifting of donor anonymity at the age of majority of the child born of the donation. However, the legislator does not provide for a specific legal regime qualifying the link between the donor and the child born of the donation. It thus proceeds to a negative qualification of a situation that nevertheless entails important legal consequences. One then wonders about the nature of this relationship and about the potential consequences induced by the lifting of anonymity, consequences that are both legal and social. This article will then make it possible to dissociate the notion of filiation and the progressive emergence of the right of access to one’s origins.
