Section 10.7 Planning Certificates are issued in accordance with the Environmental Planning & Assessment Act 1979. They contain information on how a property may be used and the restrictions on development. A person may request a 10.7 certificate to obtain information about his or her own property but generally a 10.7 certificate will be requested when a property is to be redeveloped or sold. When land is bought or sold, the Conveyancing Act 1919 requires that a Section 10.7 Planning Certificate be attached to the contract for sale.
