Mr. Duc asked whether his family had to change the land use purpose of the entire 383.4 m2. The Ministry of Agriculture and Environment responded to the question as follows: Your question concerns a specific case and falls under the jurisdiction of the local authorities. Therefore, the Ministry of Agriculture and Environment does not have the basis to provide a specific answer. The Ministry of Agriculture and Environment provides the following information: Article 220 of the Land Law stipulates the conditions and principles for land subdivision. According to point b, clause 2, in the case of changing the land use purpose of a portion of a land parcel, land subdivision must be carried out, and the minimum area of the subdivided land parcel must be equal to or greater than the minimum area of the land type after the change of land use purpose. Regarding regulations on land subdivision and consolidation, the Ministry of Agriculture and Environment has researched, advised the Government, and submitted to the National Assembly a Resolution on regulating some mechanisms and policies to remove difficulties and obstacles in the implementation of the Land Law. This includes the provision that "In cases where the purpose of use of a portion of a land parcel is changed, land subdivision is not mandatory."
