Autonomía de la voluntad y filiación: los desafíos del siglo XXI

spanish legislation on assisted reproduction techniques has involved an important change in the traditional regulations related to the determination of affiliation, especially if we consider that we can resort to these not only in the case of heterosexual couples with reproductive problems but also same-sex couples and single women. however, surrogate mothers in spain are prohibited. this has resulted in increased cases of "reproductive tourism" where people who cannot access this technique in our country, travel to another in which it is allowed, and later they aim at the recognition of the affiliation of a foreign-born child.
