The Land Registry's main functions are to:

• Administer a land registration system by maintaining an up-to-date Land Register and the related land records under the Land Registration Ordinance and Regulations.
• Provide the public with facilities for search of the Land Register and other land records.
• Provide government departments and agencies with property information.
• Process applications for the incorporation of owners under the Building Management Ordinance.
  
  

In August 1993, the Land Registry was established as one of Hong Kong's first Trading Fund Departments.

Under the trading fund model, the Land Registry is responsible for its own finances and must meet its expenditure with its own income. The Land Registry has flexibility to respond to the service needs of clients and customers through autonomy in capital investment projects to enhance services and operational efficiency.

The Land Registrar serves as the General Manager of the Land Registry Trading Fund.

The Trading Fund's Annual Report and the certified financial statements by the Director of Audit must be tabled in the Hong Kong Legislative Council each year.
