["Child &Family Social Work, EarlyView. ", "\nABSTRACT\nParental advocacy represents a crucial response to the marginalization of parents within child protection systems, aiming to empower them by amplifying their voices, ensuring their participation and supporting them through complex legal and bureaucratic processes. This article evaluates the Parental Advocacy and Information Service (PAIS), a pilot service launched in Ireland to provide independent advocacy for parents involved in child protection cases. Drawing on qualitative data from interviews and surveys with parents and professionals, the study explores how advocacy services contribute to meaningful parental participation in decision‐making, impact relationships between parents and professionals and address the emotional and informational needs of parents. The findings highlight the role of advocacy in breaking down complex information, enhancing parents' knowledge of their rights and fostering improved communication with child protection professionals. Despite challenges, the PAIS has proven to be an invaluable tool for empowering parents, reducing emotional distress and facilitating more collaborative relationships with social workers. This article contributes to the growing body of literature on parental advocacy in child protection, offering insights into its potential to transform systems of support for families.\n"]
