Handling an off-the-plan purchase dispute

Off-the-plan disputes commonly arise from construction delay, material changes, or sunset clause termination. The NSW regime gives purchasers enhanced rights, and vendors must apply to the Supreme Court before relying on sunset termination.

In short

This is an 8-step workflow for handling an off-the-plan purchase dispute in NSW, including purchaser rescission rights, vendor termination, and sunset clause issues under the Conveyancing Act 1919 (NSW).

Time: 5-15 hours depending on the nature of the dispute and whether court proceedings are needed.
Audience: NSW property lawyers acting for a purchaser or vendor in an off-the-plan dispute.

2

Identify the dispute category

Identify whether the dispute involves a material change, construction delay, defective work, or sunset clause — each triggers different statutory rights.

Tools: Quillio
3

Check material particulars

Check whether there has been a change to a material particular disclosed to the purchaser. Material changes may entitle the purchaser to rescind and recover the deposit.

Tools: Quillio
Conveyancing Act 1919 (NSW) s 66ZL
4

Assess sunset clause position

Assess the sunset clause position. A vendor who wants to terminate under the sunset clause must apply to the Supreme Court and demonstrate it is just and equitable.

Tools: Quillio
Conveyancing Act 1919 (NSW) s 66ZS
5

Consider quality-of-construction issues

Consider whether the completed lot materially differs from the approved plans and specifications and whether the building defects regime under the DBP Act is engaged.

Negotiate or escalate

Negotiate with the other party, considering price adjustment, scope variation, or deed of variation. Escalate to mediation or Supreme Court proceedings if required.

Finalise resolution or proceedings

Finalise the resolution with a deed of settlement or, if proceedings are commenced, prepare and file the relevant originating process in the Supreme Court.
