This master thesis analyzes the term of expropriation, its development throughout history and its various types. Special emphasis has been put on the two most recent acts regulating the institute of expropriation in the Republic of Croatia, namely those from 1994 and 2014. In great detail and with precision we take a look at the procedure of expropriation throughout its three phases, which include determining the interest of the state (Republic of Croatia), the course of the procedure of expropriation itself and lastly the determination of the compensation for the expropriation. Answers are given to questions like who can be the user of expropriation and what exactly can be the subject of expropriation. A critical approach is taken towards the analysis of the Expropriation and Compensation Determination Act from 2014. After the Republic of Croatia became independent and superior, the Expropriation and Compensation Determination Act from 1994 was passed. This act stated, that the protection of rights involving expropriation would be carried out in front of the Administrative Court of the Republic of Croatia. The new Expropriation and Compensation Determination Act from 2014 has brought with it some new legal institutes, while at the same time improving upon or changing the old ones. The most important reason that the new Expropriation and Compensation Determination Act has been passed, was to make assessing and determining the value of real estates easier. The value of real estates is determined the same way in all processes on croatian territory, whilst the legal basis for that is the regulation that governs the way of assessing and determining the value of real estates.
