This document discusses the role of expert knowledge in transnational and transracial adoption in Spain. It provides statistics on adoption trends in Spain since the late 1990s, with the number of international adoptions doubling between 1998-2000. It also examines adoption processes and mandatory training for prospective parents in Catalonia, which focuses on preparing parents for differences but does not tailor training based on the child's country of origin. Experts emphasize a clean break from the child's birth parents and attachment to the new family, but families may be more open than experts to rethinking transracial and transnational identities over time.
