Title: “The will of the child isn't always what's best for the child” A qualitative study on how family law caseworkers involve children in custody-, residence-, and visitation investigations in cases involving risk factors.  Our study aims to examine how family law caseworkers involve children in custody-, residence-, and visitation investigations in cases involving risk factors. The study also aims to investigate how family law caseworkers perceive the child's own wishes and to what extent the risk factors influence assessments regarding what is in the child's best interest.In this study, a qualitative methodological approach employing qualitative interviews has been utilized, employing a vignette method in combination with semi-structured interviews. The sample consists of eight active family law caseworkers located in southwestern Sweden. A thematic analysis has been conducted to interpret the empirical data.The results have been categorized into four main themes: Child Participation, family lawcaseworkers handling of risk factors, family law caseworkers assessment of the child's best interests, and family law caseworkers' room for action.The study's findings indicate that children are involved to the extent possible, considering their age and maturity. However, family law caseworkers argue that it is their responsibility to protect children from harm, and therefore, the adult perspective sometimes needs to take precedence over the children's own will in decision-making.In summary, the study's results reveal that the child's wishes are not always aligned with what is considered to be in the child's best interest. Additionally, while the child's involvement is highly valued, the presence of risk factors plays a crucial role in family law investigations regarding custody, residence, and visitation.
