Like conventional bonds, Islamic securities are not risk free. Therefore, it is important to provide solutions to manage this type of risk in the Sukuk structure. One of the remedies used in Islamic countries to prevent default is the restructuring of financial obligations. The purpose of the restructuring is to give the debtor more time to settle his obligations. This descriptive-analytic study, while studying the experience of Islamic countries in restructuring Sukuk as well as experience in usury banking in Iran, introduces restructuring, its implementation process, and also mechanisms for restructuring various types of Sukuk and analyzes it according to the viewpoints of Sharia jurisprudents. These include expanding the maturity, increasing the rate of return, Haircut, Renewal of Contract, Debt Conversion and Debt to Equity swaps. Finally, according to the jurisprudential nature of the basic contract of each type of Sukuk, the mechanism (s) appropriate to each are presented.
