In the present article, we try to jurisprudentially examine time sharing and its economic applications. However, as Iranian law, especially in the field of civil law, is based on Imamiah jurisprudence, one cannot avoid using juridical approach. The article is compiled in five sectors: literature, concepts, the reasons of time sharing’s being permissible, Grand Ayatullahs’ attitudes, and its advantages and applications. Given the concept of ownership, it was revealed that stability is not something of its essence, but rather it could be developed without that. The reasons for its being demonstrated are principal, existence of its parallel in Waqf, Solh, and reign rule. Some grand Ayatullahs’ acceptance of its validity confirms the idea presented in the article. Its acceptance has such important applications as attracting capital to the housing sector, reducing costs, and investment growth.
