Land Sales Act 1964

A vendor under an instalment contract, or the vendor’s agent, shall not tender to a purchaser a copy of an instalment contract for the sale and purchase of a lot unless the instalment contract is in the form, or one of the forms, of instalment contract annexed to the trust deed relating to the subdivision in which the lot is comprised.

Within twenty-one days after tendering a copy of the instalment contract to a purchaser, the vendor shall deliver or cause to be delivered to the purchaser a counterpart of the contract duly executed by the vendor or the vendor’s duly appointed attorney, if—

the copy of the instalment contract so tendered has been executed by the purchaser and has, within fourteen days after its having been so tendered, been delivered to the vendor or the agent of the vendor, and

the purchaser has complied with all terms and conditions required by the instalment contract to be complied with by the purchaser at or before the delivery to the purchaser of the counterpart of the contract duly executed as aforesaid.
