What is the separation of land use right certificates?
Red book separation (or land plot separation) is the division of one land plot into many smaller plots, in which each land plot after separation is issued a separate red book.
Land plot separation is still carried out to serve purposes such as: transfer, donation, inheritance, mortgage, capital contribution or change of land use purpose.
Principles of land separation that people need to pay attention to
Land plot separation in 2026 must ensure the following conditions: Land plots formed after separation have walkways, are connected to existing public transport roads, and at the same time, meet the requirements for water supply, drainage and other essential infrastructure needs.
In case land users allocate a part of the residential land area or land plots with residential land and other land in the same plot to make walkways when separating plots, they are not required to carry out procedures for changing land use purposes for this walkway area.

Errors that caused red book separation dossiers in 2026 to be returned
In the process of carrying out procedures to separate red books in 2026, many dossiers were returned by functional agencies because people made some common mistakes.
First, the land plot does not meet legal conditions: has not been granted a red book; the land has expired but has not been extended; the land is being distrained for judgment enforcement.
Second, land is in dispute but the scope and boundaries of the dispute cannot be clearly determined, leading to insufficient conditions for land separation according to the provisions of the 2024 Land Law being applied.
Third, many cases are returned dossiers due to not ensuring conditions on walkways and infrastructure, land plots after separation do not have legal walkways or cannot be connected to existing public transport roads.
Fourth, the area of the land plot after separation is smaller than the minimum level according to the regulations of the Provincial People's Committee.
Specialized agencies recommend that, before submitting applications for separation of red books in 2026, people should carefully study legal regulations and specific conditions in the locality to avoid wasting time and costs due to applications being returned many times.
