Ownership as the highest value of the constitutional order of the Republic of Croatia is invulnerable, it is binding and its holders are obliged to contribute to the general good. However, the state must must be enabled the restriction of ownership rights, otherwise it would not be able to build facilities which have general interest for the state, city and the wider socail community. The theme of this final work is the expropriation institute in the Croatian legal system regulated by the Law on Expropriation and Remuneration. This work has to clarify that although the certain right guaranteed by the constitution is invulnerable, there is always a certain exception in the legal system where the stated right can be taken or limited and the expropriation institute is a proof of this exception. The aim is to determine the characteristics and features of the expropriation in the legal system of the Republic of Croatia, and the subject is analysis of the implementation of the expropriation process, taking into account examples from practice and comparing the changes from the Law with respect to the previously applicable Expropriation Law.
