Custodial parents, often single mothers, face challenges regarding child maintenance, including a lack of financial commitments from non-custodial parents for their children’s welfare. The evidence suggests that there is a strong link between child maintenance and poverty as well as other family violence issues. In addition to their primary child and family protection duties, child protection practitioners in Ghana have a mandate to assess child maintenance concerns. This dual responsibility may have the advantage of promoting holistic child and family practices, but it could also negatively impact families when practitioners overly focus on one responsibility at the expense of the other. We sought to understand and show whether families who reported child maintenance concerns to the Department of Social Welfare and Community Development in Ghana experienced challenges beyond child maintenance and whether practitioners identified these primary protection concerns in their assessments. Findings from qualitative in-depth interviews with seventeen parents show that these families experienced domestic violence, marital conflict and child abuse and neglect beyond the scope of a standard child maintenance case. The findings highlight the importance of child protection workers conducting comprehensive family assessments to resolve ‘hidden’ family difficulties when establishing child maintenance arrangements.
