Summary Competence is an essential part of any decision-making process. In child protection, it is challenged by the controversial nature of child removals and the vulnerable situations which children and parents experience therein. This article examines how and on what grounds social workers view parents and children to be competent to give their informed view in care order proceedings and what they do if doubts about competence arise. The analysis is based on 30 interviews with social workers in Finland. Findings The professional ethos and ethics of social work were embedded in the social workers’ descriptions of children’s and parents’ competence. The social workers were confident that the parents and children (of certain age) were competent to give their informed view about whether to consent to the care order proposal and the proposed substitute home. When they spoke about competence ascribed with hesitation, they described the vulnerability of service users, as well as their attitudes and withdrawal from contact. In the cases, social workers emphasized a strength-based view of children and parents and aimed to ‘talk more’ with them and to ‘give them more time’ to support their right to give an informed view. Applications Social vulnerability and competence should be explored reflectively in relation to decision-making in child protection. A better understanding of their interrelation makes social workers more competent to support the service users’ right to be included in decision-making. Critical awareness is needed to recognize when ‘more talk’ is not enough to realize children’s and parents’ rights.
