According to Article 1 of the National Property Act, the Act is applied to the acquisition, custody, use, revenue and disposition of national property. For matters that are not provided in the Act, other applicable laws and regulations will apply. Therefore, Articles 49-54 of the National Property Act are the major legal basis for the sale of non-public-use national property

In practice, sales of non-public-use national property fall in to two categories: (1) sales or project sales—refer to the sale applied for by law by the public; and (2) sales by tendering—refer to the sale of non-public-use national property by tendering applied by the public who do not meet the requirements for sales or project sales, or the sale of property without a pre-designated purpose of use actively screened by NPA branches.
