Family involvement is a key element of Domestic Homicide Review (DHR), the form of Domestic Violence Fatality Review (DVFR) found in England and Wales. Family involvement is framed as having dual purposes: first, as a benefit to DHRs, enabling a fuller picture of victims’ experiences; second, as a benefit to families themselves, notably as a therapeutic or cathartic opportunity. However, these dual purposes have been little considered. This conceptual article responds to this absence by interrogating the purpose, process and outcomes of family involvement within DHRs.
