For decades, transnational adoption has been applied as a valuable measure for children in need of a family home, and for families to fulfill their child wish. The Hague Adoption convention (1993) was established to legally safeguard these processes. However, over the years, denouncements of illegal adoptions and malpractices arose. Notwithstanding, a lack of research giving overview of these malpractices and the consequences thereof remains. This contribution explores the experiences of adoptees in Flanders (Belgium) who experienced malpractices before, during and after their transnational adoption procedure. The research questions addressed are: “What malpractices do adoptees encounter?”, “How do adoptees experience malpractices in their adoption procedure?”, and “What needs do adoptees have?”. A self-assessment questionnaire, holding into account respondents’ own judgment, perception, experiences, and interpretation, was completed by 64 adoptees, and analyzed using both SPSS statistical software and Microsoft Excel. Furthermore, in-depth interviews with a heterogeneous group of 12 adoptees were conducted and thematically analyzed. Our findings contribute to descriptions of occurring malpractices, and finetune existing literature concerning the psychosocial impact of malpractices according to adoptees themselves. Findings illustrate intertwined consequences of more general, trauma related, identity development, and relationship issues. Although occurred malpractices cannot be undone, the adoptees having experienced malpractices highlight their needs and further necessary attention for the prevention of malpractices. Adequate attention and support for transnational adoption and those involved is discussed.
