Families often have particular vulnerabilities following armed conflict. As international humanitarian law focuses primarily on regulating the conduct of hostilities, its scope for addressing the vulnerability of families and other victims of armed conflict is, at present, conceptually and practically limited. A human security approach invites consideration of the shortcomings of existing legal frameworks in addressing vulnerability, and the development of such frameworks, in a manner that helps to build resilience and address threats. For families harmed during armed conflict, this means identifying features of the existing legal regime that operate in a manner that entrenches or fails to address their vulnerabilities, as well as structural challenges that hinder access to legal opportunities such as reparations. The article identifies several structural issues and features of the legal framework that overlook or entrench the vulnerability of families. Drawing on a human security approach, it suggests that supplementing the existing legal regime with a victim assistance framework could help to address the vulnerability of families and others harmed by armed conflict.
