Social life requirements prompt legislators to impose limitations on and even forevlose private ownership under certain circumstances, based on the public power of State institutions and for public interest; such discretion is however not absolute and State institutions are authorized to expropriate a land that the payment of its price is made and legal formalities are observed. Under Iranian legal system, the initiation of compulsary purchase measures depends on an approved plan, required financing, the implementing the plan and public promulgation of the plan however, unlike English law, citizens are not involved in the process of approving the plans and their content and no objection mechanism to plans has been predicted before the plans are approved and finalized.Under British law, compensation is not limited to the properties lying within an urban planning scheme, but it may be obligatory in case no land has been expropriated, however, the properties be harmed due to the provision of public service or subsequent use of public installations.This article, with its analytical-descriptive methodology, seeks to explain ?? aspects of Iranian and British legal systems as regards the expropriation of lands and properties and compensation methods resulting from the limitation of private ownership.
