A Section 66W certificate waives the standard five-business-day cooling-off period on private-treaty residential contracts in New South Wales, so exchange becomes immediately binding. A solicitor or barrister independent of the vendor must prepareand sign it correctly.
What is a Section 66W certificate and how does it change cooling-off rights?
New South Wales gives residential buyers a five-business-day cooling-off right on most private-treaty purchases. Pull out during that window and you forfeit 0.25% of the purchase price, which works out to $250 for every $100,000 you’ve agreed to pay, according to NSW Government guidance on contracts and deposits. It’s a modest cost designed to let buyers change their mind without wearing the full weight of a broken contract.
A Section 66W certificate waives your statutory cooling off period.
That shift matters more than most buyers realise:
- The cooling-off right disappears the moment contracts exchange.
- You can’t reinstate cooling-off after exchange if you change your mind about the waiver.
- The vendor gains certainty immediately, which is precisely why some sellers or agents push for it.
- Your financial exposure jumps from a 0.25% deposit forfeit to the full deposit, and potentially more, if things go wrong.
What must a valid Section 66W certificate include?
The Conveyancing Act 1919 (NSW) sets out exactly what makes a certificate legally effective under section 66W.
- It must be in writing. A verbal assurance from your solicitor or a text message won’t cut it.
- It must be signed by a solicitor or barrister who is independent of the vendor. They cannot act for the seller, and they cannot work in the same firm as the vendor’s solicitor.
- It must state its purpose. The document needs to identify itself as a certificate under section 66W.
- It must confirm the lawyer explained the contract’s effect. The certificate has to record that the practitioner walked the purchaser through what exchanging without cooling-off actually means.
- For corporate purchasers, the explanation must go to an officer or manager. A generic explanation to an employee with no management role will not suffice.
How do you obtain a compliant Section 66W certificate?
- Engage a solicitor early. If you’re bidding on a property this week, don’t wait until the night before exchange to make contact. Urgent appointments are common in competitive markets, but they need lead time.
- Lock down your finance position. Either get unconditional loan approval or firm written confirmation from your lender before you ask for a waiver. A conditional pre-approval is not the same thing.
- Complete building and pest inspections. Any waiver signed before these reports land is a waiver signed blind.
- Get independent advice on the contract itself. Your solicitor should walk you through special conditions, adjustments, and anything unusual in the contract of sale and the mechanics of waiving your cooling off period.
- Have the certificate prepared and signed. This happens once your solicitor is satisfied you understand the risk and have made an informed decision.
- Provide the certificate when exchanging. This is the step buyers most often overlook.
A few practical things to nail down with your solicitor before exchange day:
- Ask whether exchange will happen on paper or electronically through PEXA, and confirm your solicitor has PEXA capability if it’s the latter.
- Keep a copy of the signed certificate for your own records, separate from the version sent to the vendor’s solicitor.

Is waiving the cooling-off period worth the risk?
Waiving cooling-off has one clear upside: it makes your offer more attractive. In a competitive market, a vendor comparing two similar offers will usually favour the one that removes the five-day uncertainty window, especially where multiple buyers are circling the same property.
The downside is where buyers get hurt. Once you exchange with a 66W certificate attached, there’s no cheap way out.
So when does a waiver make sense?
- Your finance is unconditional.
- Building and pest inspections and/or strata inspection report are completed and you have reviewed and they are acceptable to you.
- You’re in a genuinely competitive situation where certainty is the deciding factor for the vendor.
And when should you avoid it?
- Your loan approval still has conditions that cannot be met.
- Inspections haven’t happened yet, or reports haven’t come back.
- You’re a first-time buyer without a financial buffer if something goes wrong.
Where a straight waiver feels too risky, ask your solicitor about negotiating specific conditions into the contract instead, or getting a written comfort letter from your lender before you commit either way.
Ready-to-use checklist before requesting a 66W certificate
Before you ask your solicitor to prepare a certificate, work through this:
- Finance is unconditional, or your lender has confirmed approval in writing.
- Building and pest inspections are complete, with quotes obtained for any urgent defects found.
- Relevant searches are done, covering title, zoning, and easements where they apply to the property.
- Your solicitor has explained what waiving cooling-off actually means for your specific contract, and is ready to sign at exchange.
- You’ve had the contract reviewed by a solicitor.
How do you verify the solicitor issuing your certificate is truly independent?
Independence isn’t a formality, it’s the entire legal foundation of a valid certificate. Section 66W specifically requires that the signing solicitor or barrister is not acting for the vendor and does not work in the same firm as the vendor’s solicitor.
What happens if a certificate is defective or improperly issued?
A certificate that fails to meet section 66W’s requirements may be treated as though it was never given, which means the cooling-off period potentially never ended. That’s a significant problem for a vendor relying on an immediately binding contract, and it can open the door for a purchaser to argue they still hold cooling-off rights they thought they’d waived.
Where independence is compromised, the certificate can be challenged as invalid.
Disputes over defective certificates typically end up resolved through negotiation between the parties’ solicitors, or in more serious cases, before the NSW courts or tribunals if the contract itself is challenged. Because the stakes involve a binding property contract, this isn’t the kind of dispute you want to discover you’re in without legal representation of your own.
The safest remedy is prevention. Confirm every statutory element before exchange, because unwinding a defective certificate after the fact is slower, costlier, and less certain than getting it right the first time.

FAQ
How much does a Section 66W certificate cost?
Costs vary by firm and complexity, so ask for a specific quote when you engage a solicitor, but it’s typically bundled into standard conveyancing or independent legal advice fees rather than charged as a large standalone cost.
Who prepares a contract of sale in NSW?
The vendor’s solicitor or licensed conveyancer prepares the contract of sale before the property goes to market, and the purchaser’s independent solicitor reviews it, negotiates any amendments, and, if requested, prepares the separate Section 66W certificate.
How long does it take to get a Section 66W certificate?
Timing depends on how quickly finance is confirmed unconditional and inspections are completed, but once those checks are done, a solicitor can typically prepare and sign a certificate within a short period of time, provided there’s enough notice before exchange.
Can a Section 66W certificate be added after contracts exchange?
Generally, no. The certificate must accompany the signed contract at the moment of exchange.
