A section 66W certificate is a document prepared and signed by the buyer’s conveyancer noting that they have explained to the buyer that the cooling-off period has been waived by the buyer.

This is a common document requested by the seller as it provides certainty that when contracts are entered into, the buyer is committed to going ahead with the deal. It’s important that the buyer has completed all due diligence on the property and is comfortable committing to the purchase before this document is provided.
