Hanoi is implementing a 9-day campaign to "clean up and enrich land data" in 126 communes and wards to digitize, synchronize and standardize land databases.
For this campaign to go smoothly, Dr.LS Dang Van Cuong - Head of the Legal Advocate Office, Hanoi Bar Association said that people need to bring certificates of land use rights, house ownership rights (red books, pink books); citizen identification cards or ID cards.
These are the two most important types of documents and also the legal basis for directly determining land use rights as well as the identity of the land user, for competent authorities to scan, compare and enter data

According to lawyer Dang Van Cuong, in many specific cases, people may need to provide additional documents. For example, transfer contracts, donations, inheritance documents, land allocation or lease decisions, etc. These documents are not always mandatory, but will be very necessary if the authorities need to verify the continuity and legality of land use rights.
In some special cases, providing other documents is a necessary condition for the data synchronization process to be accurate. For example, if the land plot does not have a red book, people should present existing legal documents such as handwritten sales documents, declarations, tax payment receipts or confirmation from local authorities.
If the land user has died, the heir must prove his rights through birth certificate, death certificate or legal inheritance document. In case the land is in dispute, people still have to declare, but the dossier will be classified separately for later handling.
When the People's Committees of wards and communes have notified, land users and owners of assets attached to land need to proactively coordinate and provide complete records and related documents for the authorities to collect and scan documents according to regulations.
For cases where the certificate has been lost, damaged or has not been issued, people should promptly contact the Land Registration Office or the People's Committee of the ward or commune where the land is located for instructions on procedures for reissuance or reissuance according to the law.
In addition, the city encourages people to use online public services to look up information, update data and monitor the progress of file processing. This not only helps reduce travel time but also contributes to ensuring publicity, transparency and improving the efficiency of land data management.
In other words, in most cases, people only need to prepare a red book or pink book with a citizen identification card, while other documents only need to be supplemented when falling into special situations. This is a way to make the authentication process go smoothly and quickly, while ensuring that people's rights are accurately recorded in the digital land data system.
