Protecting the private property of foreign investors from non-commercial risks such as expropriation, confiscation and nationalization is of interest to states and investors alike, in order to attract investors and provide them with legal guarantees that do not conflict with the sovereignty of the state and its desire to achieve economic development. This study aims to shed light on this protection according to the provisions of Omani legislation in order to evaluate this legislation and find solutions to any related issues. The study followed the analytical and comparative approaches, by analyzing Omani legislation, jurisprudential opinions and judicial rulings, and comparing them with the Egyptian and Emirati legal systems and international investment arbitration provisions to determine the extent to which the Omani legislator responds to international standards in the field of protecting foreign investor's property. The study was divided into two chapters, the first concerned with the protection of the foreign investor's property in the face of expropriation by explaining what expropriation and public benefit are, the guarantees of determining public benefit and the effects thereof, while the second chapter is concerned with the protection of the foreign investor's property in the face of confiscation and nationalizations by explaining what confiscation and nationalizations are, the guarantees related to them, the restrictions on state authority and the effects thereof, the study concluded with a number of findings and recommendations that contribute to the protection of foreign investor's property in order to achieve the interest of the state in attracting investors.
