Urban Exploration (URBEX) is a relatively recent leisure activity that is directly related to the exploration of abandoned and unused objects and areas, collectively referred to as brownfields. This survey of modern ruins is conducted for private purposes only, for the purpose of photo-documentation or video-visualization and their sharing within the community or presentation to the public. Due to the fact that the properties visited in this way are owned by other entities and there is often a real risk of damage to property and health, it is necessary to identify those legal aspects of URBEX that normatively regulate the relationship of both parties concerned. The aim of this paper is to define, within the framework of Czech legal standards, the rights and obligations of the property owner, which flow for them in connection with the realization of URBEX on real estate that is his property.
