Drawing on socio‐legal literature and fieldwork in South Sudan, this article argues that international aid groups operating in conflict settings create and impose a rules‐based order on the local people they hire and on the domestic organizations they fund. Civil society actors in these places experience law's soft power through their daily, tangible, and mundane contact with aid agencies. As employees they are subject to contracts and other rules of employment, work under management and finance teams, document routine activity, and abide by organizational constitutions. In analyzing how South Sudanese activists confront, understand, conform to, or resist these externally imposed legal techniques and workplace practices, this article decenters state institutions as sites for understanding law's power and exposes how aid organizations themselves become arenas of significant legal and political struggle in war‐torn societies.
