Introduction: This study adult guardianship for people with impaired decision- making capacity will be analysed. Three different counties in Skåne, Sweden will be studied with the perspective of their recruitment process and the supervision of the adult guardian. The purpose of the study is to look closer at how the counties quality assures their work and how they can guarantee legal certainty to the people with impaired capacity. In today’s society there’s an increasing amount of people in need of an adult guardian, both in Sweden and around the world. To have an adult guardian is a drastic restriction in a person’s life, as they lose all their legal rights, whereas the guardianship is allowing another person to take over their decision making. Therefore this measure should only be used as the last resort of action. Today we’re often fed with different horror stories about non- working adult guardians, who misuse their power-position in another person’s life and the society speculates whether this measure is for the person’s best or not. Therefore this study will be looking closer at how this procedure is implemented in practice in the countys.Method: This study is a documentary study based on swedish laws, national guidelines, public documents and internal guidelines from each county. The collected material was analyzed with a thematic analysis method.Result: Current laws and national guidelines leave a room for interpretation for the countys to organise their work with the procedure of adult guardianship. The study showed both differences and similarities in the counties work procedure. The studied counties were variously generous with sharing their internal guidelines and documents. Some counties used the national guidelines more frequently, while others had established more internal guidelines for the employee to use.Conclusion: All the counties had established routines and guidelines which can be seen as measures in the form of both quality assuring and legal certainty for the people with impaired decision-making capacity. The area of adult guardianship is unexplored, which could benefit from the counties sharing their experiences with each other and be further explored.
