What Sellers Need to Know Before Listing Their Property in NSW

If you are preparing to sell a home or investment property on the Upper North Shore, the legal groundwork matters as much as the marketing campaign. Caspian Legal’s conveyancing team, based in Hornsby, helps vendors get their contract and disclosure documents right before the property goes to market.

• An agent cannot market a residential property for sale until a contract of sale with the required documents attached is ready and available for inspection, under section 63 of the Property and Stock Agents Act 2002 (NSW).
• Separately, NSW law sets out what must be attached to that contract. This is the vendor disclosure obligation under section 52A of the Conveyancing Act 1919 (NSW).
• Private treaty buyers generally get a 5 business day cooling-off period. This does not apply to a genuine auction sale, or where the buyer’s solicitor or licensed conveyancer signs a section 66W certificate waiving it.
• If the property has a swimming pool or spa, a valid certificate of compliance, a certificate of non-compliance, or a recent occupation certificate plus registration, must be attached to the contract, under the Conveyancing (Sale of Land) Regulation 2022 (NSW) and the Swimming Pools Act 1992 (NSW).
• Your agent must record a reasonable estimate of the likely selling price in the agency agreement. Underquoting is a specific offence under the Property and Stock Agents Act 2002 (NSW), and it is worth understanding as a seller even though the duty sits with the agent.

Jurisdiction

This article applies to the sale of residential property in New South Wales, and is written with Hornsby and Upper North Shore vendors in mind. Property law, disclosure requirements and cooling-off rules differ in other Australian states and territories, so if your property is outside NSW you should get advice from a solicitor or conveyancer licensed in that jurisdiction.

Selling Can Feel Like a Lot to Get Right

Between choosing an agent, preparing the property and deciding on a price, it is easy to leave the legal side of a sale until the last minute. In NSW, however, a valid contract of sale with the correct documents attached needs to be ready before your agent can lawfully begin marketing, and getting this wrong can slow down your sale or give a buyer grounds to raise issues later. Caspian Legal can review your title and prepare your contract of sale before you list, to help reduce the risk of unexpected issues once an offer comes in. You can call the team on 02 7264 3200 to arrange an initial conversation about your sale.

Key Terms, Explained Simply

A few terms come up repeatedly in the selling process. Here is what they mean in plain English.

Term	What It Means
Vendor	The legal term for the person or entity selling the property.
Contract of sale	The legal document that sets out the terms of the sale. In NSW it must have certain documents attached before it is signed by a buyer.
Vendor disclosure	The seller’s legal obligation to attach specified documents and warranties to the contract, so the buyer knows the true state of the title and the land before they commit.
Prescribed documents	The specific documents the law requires to be attached to a contract of sale, such as the title search, planning certificate and drainage or sewer diagram.
Exchange	The point at which both parties sign identical copies of the contract and swap them, usually through their solicitors or conveyancers. This is when the sale becomes legally binding (subject to any cooling-off period).
Cooling-off period	A short period after exchange, usually 5 business days, during which a private treaty buyer can withdraw from the contract, generally forfeiting 0.25% of the price.
Section 66W certificate	A certificate signed by the buyer’s solicitor or licensed conveyancer that waives the cooling-off period, making the contract immediately binding on exchange.
Settlement	The day ownership legally transfers to the buyer and the balance of the purchase price is paid.
Certificate of compliance	A certificate confirming a swimming pool or spa meets NSW safety standards. Required to be attached to the contract if the property has a pool.
Agency agreement	The written contract between a seller and their real estate agent, which must record the agent’s estimated selling price.

Before You List: A Step-by-Step Guide for Sellers

Every sale is different, but most NSW vendors move through the same general sequence. This is general guidance, not a substitute for advice tailored to your property.

1. Engage a conveyancer or solicitor early. Under section 63 of the Property and Stock Agents Act 2002 (NSW), an agent cannot lawfully market your property until a compliant contract of sale is ready, so it is worth doing this before you sign with an agent.
2. Order your prescribed documents. These typically include a current title search, a planning certificate under section 10.7 of the Environmental Planning and Assessment Act 1979 (NSW), and a sewer service diagram or drainage diagram, as required by Schedule 1 of the Conveyancing (Sale of Land) Regulation 2022 (NSW).
3. Check whether pool compliance applies. If there is a swimming pool or spa on the property, arrange an inspection and obtain a valid certificate of compliance. If the pool is not compliant, a certificate of non-compliance can be attached instead, though this shifts the cost of rectifying defects to the buyer after settlement.
4. Decide on a method of sale. Private treaty, auction and expressions of interest each have different implications for cooling-off rights and negotiation, discussed further below.
5. Review the agency agreement carefully. Check the commission structure, marketing costs, the agreement’s length, and the agent’s estimated selling price before you sign.
6. Understand your buyer’s cooling-off position. If you are selling by private treaty, most buyers will have a 5 business day cooling-off period unless their solicitor provides a section 66W certificate. This affects how firm an early exchange really is.
7. Consider adjustments at settlement. Land tax, water rates and council rates are typically adjusted between buyer and seller as at the settlement date, so it helps to know your position on these before you exchange.
8. Have your contract ready before you go to market. Buyers and their solicitors will expect to review the contract promptly, and delays here can cost you a sale in a competitive market.

Private Treaty or Auction? What Changes for You as a Seller

The method of sale affects your legal position as much as your marketing strategy. Here is a general comparison for NSW residential property.

Feature	Private Treaty	Public Auction
Cooling-off period	Generally 5 business days applies to the buyer, unless waived by a section 66W certificate.	Does not apply to a genuine auction sale (Conveyancing Act 1919 (NSW), s 66T).
When the sale becomes binding	On exchange, subject to any cooling-off period.	On the successful bidder signing the contract at the fall of the hammer, with no cooling-off period.
Price negotiation	Direct negotiation, often with room to adjust price and terms.	Set by competitive bidding on the day, against a reserve price.
Certainty for the seller	Can be less certain until the cooling-off period ends (if it applies).	Generally higher certainty once the property is sold under the hammer.
Typical preparation	Contract and disclosure documents should still be ready before marketing.	Contract must be available for the auction, along with pool compliance documents if applicable.

Document Checklist Before You List

Gathering these documents early avoids delays once a buyer is ready to exchange.

Document	Why It Matters	Legal Basis
Current title search	Confirms legal ownership and any registered interests on the title.	Conveyancing (Sale of Land) Regulation 2022 (NSW), Sch 1
Planning certificate (s 10.7)	Sets out zoning and planning restrictions affecting the land.	Environmental Planning and Assessment Act 1979 (NSW); Conveyancing (Sale of Land) Regulation 2022 (NSW)
Sewer service diagram or drainage diagram	Shows sewer connections, or confirms unsewered status.	Conveyancing (Sale of Land) Regulation 2022 (NSW), Sch 1
Swimming pool certificate of compliance or non-compliance (if applicable)	Confirms whether the pool and its barrier meet NSW safety standards, or transfers the rectification obligation to the buyer for 90 days after settlement.	Swimming Pools Act 1992 (NSW), s 22D; Conveyancing (Sale of Land) Regulation 2022 (NSW), Sch 1
Owner-builder consumer warning (if owner-builder work was done within about the last 7 years)	A required warning that owner-builder work is not covered by home building compensation cover. Owner-builders cannot obtain this cover themselves.	Home Building Act 1989 (NSW), s 95; NSW Fair Trading guidance
Strata documents (for units and townhouses)	The property certificate for the lot and common property, the strata plan and registered by-laws are prescribed attachments. Minutes, levy records and the strata roll are usually obtained separately, through your own strata search.	Conveyancing (Sale of Land) Regulation 2022 (NSW), Sch 1; Strata Schemes Management Act 2015 (NSW), s 182
Signed agency agreement	Confirms your instructions to the agent, including the agent’s estimated selling price.	Property and Stock Agents Act 2002 (NSW)
Rates, water and land tax details	Council rates, water rates and land tax are adjusted between buyer and seller as at settlement under the contract’s standard conditions. A land tax implied term also applies to all sale contracts.	Conveyancing (Sale of Land) Regulation 2022 (NSW), cl 8 (land tax); standard contract conditions for rates and water

What Not to Do

A few common missteps can slow your sale or create legal risk.

• Do not advertise or accept offers before your contract of sale and prescribed documents are ready.
• Do not instruct your agent to advertise a price below their genuine estimated selling price.
• Do not assume a verbal agreement on price is binding. In NSW, a sale is generally not binding until contracts are exchanged.
• Do not overlook pool or spa compliance if the property has one. Missing certificates can give a buyer grounds to rescind.
• Do not sign an agency agreement without checking the commission, marketing costs and the agreement’s term.
• Do not leave known defects, encumbrances or building work undisclosed. Non-disclosure can affect the buyer’s rights after exchange.

Common Mistakes and Myths

Myth: an agent can advertise whatever price attracts the most interest. In reality, the Property and Stock Agents Act 2002 (NSW) requires the agent’s advertised price to reflect their genuine estimate, recorded in the agency agreement, and underquoting is an offence.

Myth: cooling-off rights are the same at auction and private treaty. They are not. A genuine auction sale does not carry a cooling-off period, while most private treaty sales do, unless waived.

Myth: you only need a solicitor once you have a buyer. In practice, preparing your contract and gathering disclosure documents before you list avoids delays and reduces the risk of a buyer rescinding later.

What Happens at Your First Consultation

An initial conversation with Caspian Legal usually covers your title and any existing mortgage or caveat, the documents needed for your contract of sale, whether pool compliance or owner-builder disclosure applies to your property, and your preferred method and timing of sale.

Frequently Asked Questions

Do I need a solicitor to sell my house in NSW?

You are not legally required to use a solicitor, but a contract of sale with the correct disclosure documents attached is a legal requirement, and a solicitor or licensed conveyancer prepares this for you and manages exchange and settlement.

What happens if I don’t attach the required documents to the contract?

If a prescribed document is missing or a required warranty is not given, a buyer may have a statutory right to rescind the contract within a set period after exchange, under the Conveyancing (Sale of Land) Regulation 2022 (NSW).

Does the cooling-off period apply if I sell at auction?

No. A genuine sale at public auction is not subject to a cooling-off period. If the property is passed in and a contract is exchanged later that same day, it also does not apply, but the position can depend on how the auction was conducted.

What if my property has a swimming pool?

You will generally need to attach a valid certificate of compliance, a certificate of non-compliance, or a recent occupation certificate together with pool registration, to the contract before exchange. If you attach a certificate of non-compliance, the buyer takes on the job of fixing any listed defects within 90 days of settlement.

Can my agent quote any price they like?

No. Under the Property and Stock Agents Act 2002 (NSW), an agent must record a reasonable estimate of the likely selling price in the agency agreement, and advertising a lower figure can be an offence known as underquoting.

How long does the process take from listing to settlement?

This varies with the market and the method of sale, but once a contract is exchanged, settlement is commonly around 6 weeks later, subject to what the parties agree.

What is a section 66W certificate, and does it affect me as a seller?

It is a certificate the buyer’s solicitor or licensed conveyancer can sign to waive the buyer’s cooling-off period, which can give a seller more certainty on exchange. Whether to request one, and when, is worth discussing with your solicitor.
