The paper discusses the issue of the presence of solidaristic views of Léon Duguit in the process of creating property law in the years 1945-1946 in People’s Poland. The author verifies the hypothesis that in the early years of People's Poland, Polish lawyers, including prominent activists of the new authorities involved in the unification of law and the implementation of ownership-related transformations, based their actions on the solidaristic concept of law by Léon Duguit, which was used as a justification for socio-economic changes, thus allowing to hide their actual inspirations under the pretext of so-called socialization of law, especially property law. An important element of the article is also the temporal context associated with the ideological changes taking place within the legal discourse conducted in legal journals in the early years of People’s Poland.
