One of the demands of property owners is the legal registration of their property. In recent years, new laws regarding the registration of real estate have been enacted and implemented. One of the tools that significantly reassures buyers is the ownership deed. Considering the high number of legal disputes related to real estate, as well as the occurrence of various crimes and frauds, buying, selling, mortgaging, and renting, and the need to create a transparent framework for the transfer and registration of properties, the Law on the Obligation of Official Registration of Transactions was approved. However, this law has faced legal and non-legal challenges during its implementation. This research examines the advantages, implementation problems, enforcement guarantees, and objectives of this law. The study was conducted through library research using articles, website reviews, and other sources. The findings show that according to the law, documents related to contracts concerning real estate and related rights must be registered in notary offices and registration departments. The purpose of implementing this law is to organize transfers arising from transactions with informal documents, regulate real estate brokers, facilitate the monitoring of immovable properties and transactions by the authorities, reduce related legal disputes, and clarify the buying and selling of real estate. Additionally, restoring real estate brokers to their legal and inherent roles is also one of the goals of this law.
