The main purpose of this research paper is to analyze the conditions, extent, and reasonable grounds for the acquisitive prescription of public real properties (i.e., those owned by the state treasury and local government units), taking into account the exclusion time for public properties to be subject to the possibility of prescription. The acquisitive prescription of real properties is one of the methods used to regulate the legal status and for the owner to obtain a title of ownership for the property.The analysis was carried out on the example of the city of Krakow. This allowed me to assess the causes and effects as well as the scale of the practical implementation of this legal institution. The final results of the performed research study are proposed actions that should be taken as part of the public property management process aimed at protecting ownership rights by means of stopping the course of acquisitive prescription. The results of the research studies have proven the legitimacy of introducing legal regulations limiting the possibility of the acquisitive prescription of public properties.A comparison of the reasonable grounds and dates of the acquisitive prescription of the real properties in Poland with those in force in other countries (such as the United Kingdom and Germany) was also performed.
