This paper presents the results of qualitative survey, which goal was to gain insight into the experiences of experts in assisting the adoption of older children. Four social workers and four psychologists who have many years of professional experience in preparing and implementing adoption have participated in the research. The data were collected by a semi-structured interview method and processed by qualitative content analysis. The obtained results from the perspective of experts point to the difficulties encountered before, during and after the adoption of older children and to the key factors for the successful realization of such adoption. Among the most commonly encountered difficulties are the specific characteristics of the child, the child's past, the consequences of the previous child's accommodation and the fears of potential adoptive parents. Key factors for the successful implementation of the adoption of an older child are personal characteristics of potential adoptive parents, high quality preparation of participants in the adoption process, support after the adoption, and improvement of the adoption process and the social welfare system related to adoptive affairs. Finally, the need for further development of the system of adoption in the Republic of Croatia has been emphasized, especially in the segment of adopting a specific category of older children.
