This research explored why some separated fathers find it difficult to work with their child’s mother to establish a collaborative parenting arrangement, and to access support which might help them do so. The report was commissioned to inform the development of Help and Support for Separated Families – a new initiative which seeks to help families to work together during and after separation. There was a particular focus on fathers from disadvantaged and Black and Minority Ethnic (BME) communities. The research took place in March and April 2012 and involved eight focus groups in London, with fathers who are engaged in initiatives run by Working With Men – a London based charity which is already working with this “hard to reach” group.
