The objective of the present study was to examine the concept and characteristics of public services and private contracts, to enhance the appeal of such agreements to both government and other executive entities, as well as to the parties involved. The present study was carried out utilizing a descriptive-analytical qualitative approach, employing the library method. According to the findings of the study, public service is one of the fundamental principles in Iran's administrative law. The Constitution of the Islamic Republic of Iran delineates several principles wherein notable instances of public services are cited and their administration is delegated to the government. Privatization of public services involves reducing or removing government control and involvement in the creation of supply and demand mechanisms. This process also entails transferring ownership or control of the executive and economic institutions from the government to the private sector through private contracts. In contemporary times, agreements have become a crucial component in the provision of public services. This is primarily due to the growing demand for such services across various sectors, coupled with the limited financial resources available to governments in the public service domain. Consequently, the significance of private contracts has increased twofold. A thorough understanding of both general and specific regulations, as well as the various legal frameworks related to private contracts, is essential for adherence to the governing principles of such agreements.
