In Note (3) of Article (10) of the Law on the "Obligation to Officially Register Immovable Property Transactions", by validating the place of possession, the process of issuing ownership documents in rural, agricultural and garden lands has been revolutionized, and in addition to turning away from the demand-oriented nature of the registration request, the Islamic Revolution Housing Foundation and the Agricultural Jihad have been designated as the institutions responsible for verifying ownership possession, examining the site, preparing a map, and filing a file in order to issue "possessory ownership documents". An institution whose acceptance and full implementation can achieve the pending goals of registration laws, including the Comprehensive Law on the Boundary Survey, which provides for the issuance of ownership documents for all lands and properties within the geographical boundaries of the country. However, entrusting the specialized duties of the registration organization to non-specialized agencies and implementing this institution without considering the property rights that have been registered in the implementation of previous laws will lead to increased disputes and confusion in the field of ownership. This article, which includes a comparative study of possession ownership documents, will present suggestions for the systematic implementation of the aforementioned note.
