The contract of sale is the legally binding document at the centre of every NSW property transaction. Understanding what it must include, what buyers and sellers should look for, and what can be changed before exchange helps you move through the process with confidence.

This page provides general information about NSW property law and is not legal advice. Every transaction is different. Before signing or exchanging a contract, get advice from a licensed conveyancer or solicitor.

What is a contract of sale?

A contract of sale is the written agreement between a buyer (purchaser) and a seller (vendor) for the transfer of property in NSW. Once both parties have signed and dated their respective copies and the contracts are physically exchanged (or exchanged electronically), the transaction becomes legally binding on both sides.

In NSW, the Conveyancing Act 1919 (NSW) and the Conveyancing (Sale of Land) Regulation 2022 (NSW) govern the form and content requirements for contracts of sale of residential property. The regulation prescribes which documents must be attached before the contract can be offered for sale.

Most residential property contracts in NSW use a standard form prepared by the Law Society of New South Wales and the Real Estate Institute of NSW. Standard terms cover the price, deposit, settlement date, included fittings and fixtures, and what happens if either party defaults. A conveyancer or solicitor may also add or remove special conditions.

Documents the vendor must attach

Under the Conveyancing (Sale of Land) Regulation 2022 (NSW), the vendor's conveyancer or solicitor must attach several documents to the contract before it is offered for sale. These disclosures give the buyer information about the property's legal, planning, and physical status.

The required attachments include:

If required documents are not attached, a buyer may have the right to rescind (withdraw from) the contract within a statutory cooling-off period. The specific rights depend on which document was missing and whether the transaction proceeded to exchange. Advice from a conveyancer is essential before relying on a rescission right.

What buyers should check

A buyer's conveyancer will review the contract and raise any issues before you exchange. However, it helps to understand what you are looking for. Common issues in NSW contracts include:

What can be negotiated

The contract of sale is a starting point, not a take-it-or-leave-it document. Before exchange, your conveyancer can request changes to standard terms or add special conditions. Common areas of negotiation include:

Your conveyancer or solicitor advises you on what is reasonable to request given the market conditions and the strength of your negotiating position.

Common special conditions

Special conditions are clauses added to the standard contract to suit the specific circumstances of the transaction. They must be drafted carefully so they are enforceable. Common examples include:

Exchange vs settlement: what is the difference?

These two terms are often confused.

Exchange of contracts is the moment when both parties sign their respective copies of the contract and exchange them (physically or electronically). This is the point at which the transaction becomes legally binding. Before exchange, either party can walk away without penalty. After exchange, withdrawal exposes the defaulting party to legal consequences, including forfeiture of the deposit (by the buyer) or a damages claim.

Settlement (completion) is the later date, typically 42 days after exchange, when the purchase price is paid, mortgages are registered or discharged, and legal ownership transfers to the buyer. The buyer receives the keys at settlement. Settlement in NSW is conducted electronically via the PEXA platform, which has been mandatory for most residential transactions since 2019.

Between exchange and settlement, the buyer carries out final inspections, arranges building insurance (usually from the date of exchange), and prepares finance for settlement day. The vendor keeps the property in the same condition as at the date of exchange.

Frequently asked questions

What is a contract of sale for property in NSW?

A contract of sale is the legally binding agreement between a buyer and seller for the purchase and transfer of a property in NSW. Under the Conveyancing (Sale of Land) Regulation 2022 (NSW), the vendor must attach specific documents (title search, Section 10.7 certificate, and others) before offering the contract for sale.

Can I negotiate the contract of sale in NSW?

Yes. The contract of sale is a negotiated document. Settlement dates, deposit amounts, inclusions and exclusions, and special conditions can all be changed before exchange. Your conveyancer advises on what to request and drafts any amendments.

Who prepares the contract of sale in NSW?

The vendor's conveyancer or solicitor prepares the contract. The buyer's conveyancer reviews it, identifies any issues, and negotiates changes before exchange. Buyers should not sign or exchange without their own conveyancer reviewing the contract first.

What is the difference between exchanging contracts and settlement?

Exchange is when both parties sign and exchange their copies of the contract, making it legally binding. Settlement is the later date (typically 42 days after exchange in NSW) when the price is paid, title transfers, and the buyer gets the keys.

What documents must be attached to a NSW contract of sale?

The vendor must attach a title search, a Section 10.7 planning certificate, a sewerage diagram, and (for strata properties) a strata inspection report. Missing required documents can give the buyer rescission rights under the Conveyancing (Sale of Land) Regulation 2022 (NSW).
