Despite the focus of my work being the types of surrogacy gestation in Spain and the emerging problems caused by the lack of regulation in relation in terms of determining the affiliation of children, I will also refer to the position of European Court of Human Rights (ECHR) towards this topic. In order to tackle these issues, I have taken into consideration two sources: On the one hand, Roman sources from which I have been able to set the types of surrogacy gestation existing at this time (locatio ventris or locatio conductio). On the other hand, I will analyse the current increase in the number of legal cases on this matter in recent years and the legal evolution that has unfoldin this regard. Regardingits legal nature, the conducted (resulting) analysis is essentially based on the contractual character of surrogacy gestation and these consequences. Finally, I will insist on the need to regulate this matter in Spain.
