The organization of the disability field in France is undergoing regulatory and institutional changes to respond to new needs on the part of users. Organizations created by families are at the heart of these dynamics and must adapt. Our main hypothesis is that the existing institutional logics are, in many cases, unsuited to the aspirations of the accompanied persons. Faced with this situation, associative actors are starting a process of transformation of the support services offered, which encounters resistance to change. Our contribution analyzes a French association, emblematic in its size, history and objective in the disability sector. We propose questioning to what extent the development of new support services to social life crystallizes the current changes in the disability sector. Our theoretical anchoring is based on the organizational and strategic analysis of associations.
