The dissertation addresses the topic of the allegations of the real estate property in the Omani legislation and so I have divided the research into two chapters preceded by a primer study-survey of the real estate property in the Sultanate of Oman and the way of its registration. The study focuses on the scope of possibility of the land and real estate acquisition in the Sultanate of Oman through possession, seizing and the title-deed and how each of them can be considered as an exigency reason for earning the land property. Also the study included detailed manifestation for the phases being passed through by the decision of proving the real estate property in the Sultanate. The dissertation came to a bunch of the most remarkable outcomes and recommendations that have been inserted at the research winding up, among of which are: 1- The Omani legislator has admitted the possession and the pre occupation that preceded the year of 1970 and downward and the reviving of the abundant or seized and the title-deed land, considering them exigency reasons for earning the land property of the possession subject-matter in case its conditions are fulfilled. 2- The committees of land affairs or the local committees for the land affairs: They are the competent bodies to look into the land property applications and the allegations related to the land occupation preceded 1st of January 1970 and the succeeding ones. Also those allegations related to the white-land (free space) free of occupation and monuments of which is stipulated in the land law issued by the Royal decree No. 5/80. The decision of the real estate ownership registration passes through multiple phases: the phase of submitting the application and registering it, the phase of investigating the application, the phase of inspection, the phase of issuing the recommendation and the phase of the recommendation post-issuance. 4- Finally, we do recommend establishing a competent department to fix the real estate property to be one of the public departments attached to the Ministry of Housing in order to settle all disputes arise while looking into these allegations.
