Vendor Disclosure & Due Diligence

Node 35230 examines the statutory vendor disclosure obligations that apply to the sale of Australian real property, and the corresponding due diligence steps typically undertaken by a purchaser before exchange or during a conditional period. Every Australian state and territory imposes some form of pre-contractual disclosure obligation on a vendor, requiring the vendor to provide specified information or documents concerning the property and title before the purchaser becomes contractually bound, though the form, timing, and content of that disclosure vary materially between jurisdictions.

Vendor disclosure is complemented, rather than replaced, by purchaser due diligence. Statutory disclosure addresses matters the vendor is required to reveal, such as title particulars, zoning, and specified encumbrances, while due diligence extends to matters within the purchaser’s own responsibility to investigate, including the physical condition of the property, typically assessed through building and pest inspection, and searches of council, planning, and other public records. A failure by a vendor to comply with statutory disclosure obligations may entitle a purchaser to rescind the contract or claim compensation, depending on the jurisdiction and the nature of the deficiency.

This node provides technical reference for conveyancers, property lawyers, and transacting parties on the statutory disclosure framework and standard due diligence practice applicable to an Australian property transaction, ahead of the condition and warranty detail addressed in node 35240.

This node addresses statutory vendor disclosure obligations applicable to the sale of Australian real property and the standard categories of purchaser due diligence undertaken in connection with a transaction, including title, planning, and physical condition inquiries. It does not address the physical and structural due diligence methodology applied by building inspectors, addressed in the 33500 series, nor the taxonomy of contractual conditions and warranties through which due diligence outcomes are given contractual effect, addressed in node 35240.

Coverage reflects material variation between states and territories in the form and timing of statutory disclosure, from documents attached to the contract before exchange to disclosure statements provided within a prescribed period after exchange.

• Conveyancing Act 1919 (NSW)

Vendor disclosure and due diligence obligations manifest differently according to the jurisdiction and the matters affecting a particular property, though the underlying purpose of informing the purchaser before a binding commitment is common to each.
