The main aim of the present graduation thesis is to show the possible ways of compensation for all real estate subject to nationalisation, and to evaluate individual forms of the private possession. The thesis consists of the Introduction, the 6 chapters and the Conclusion. The 2nd chapter is more general as it unfolds the historical laws that set up base for the nationalisation of all the possessions (the agrar reform, the confiscation). It also includes the definiton for a possession, because the whole thesis is about legal proceedings that lead to some completely new relations to possession. The 3rd and the 4th chapters are dedicated to the Denationalisation Law and describes basic characteristics of the law such as purposes of the law, rightful claimants, ways of restoration of possession, institutions involved, etc. The 5th chapter is the most important one as it speaks of the different ways of restoration of possession and its evaluation connected to the sublaws. This chapter also speaks of the substantial enlargement or reduction of the real estate value. It mentions the elements having an impact on the compesation level as well. The conclusion lists the main ideas extracted from the thesis as a whole
