Buying in NSW: how to read the contract for sale
Read the NSW sale contract as a combination of legal terms, title and property-specific disclosure. Match its documents to the property and your intended use, resolve important gaps before exchange, and confirm the applicable cooling-off or waiver position. Physical condition, approval history and strata funding need their own evidence alongside the legal review.

Get the contract while there is still time to act
Ask for the complete current contract as soon as you are seriously interested. NSW's sales-contract requirements require a proposed residential sale contract to be available before marketing. Send the whole bundle, including special conditions and attachments, to your NSW solicitor or licensed conveyancer. A front page and an agent's assurance are not enough to assess what you would agree to.
Begin with your intended use. Tell the reviewer if you need vacant possession, want to extend, rely on a parking space or intend to use a converted garage as a bedroom. A restriction that is manageable for one buyer may defeat another buyer's reason for purchasing. That context helps turn a document review into specific questions and proposed contract changes.
Read the attachments against the property you inspected
The required bundle depends on the title and property. The regulator's checklist covers title, drainage, planning and relevant title dealings, together with prescribed notices and additional off-the-plan documents. Have the reviewer check the applicable requirements rather than treating this overview as an exhaustive attachment checklist.
| Material | What it helps establish | What to cross-check |
|---|---|---|
| Title search and deposited or strata plan | The legal parcel, registered interests and lot arrangement | Address, apartment, parking, storage and the property shown in the marketing. |
| Easement, covenant or restriction instrument | The terms behind a short title notation | Who benefits, where it applies and how it affects the intended use or works. |
| Section 10.7 planning certificate | Prescribed planning information about the land | Certificate date, relevant controls and whether further council information is needed. |
| Drainage and service diagrams | Recorded private drainage or authority assets, depending on the diagram | Actual buildings, later additions and any proposed extension or pool. |
| Special conditions and front-page particulars | The negotiated obligations and commercial terms | Deposit, settlement, possession, inclusions, exclusions and altered remedies. |
| Property-specific material | Pool, strata, off-the-plan or other applicable disclosures | Which documents and exceptions apply to this particular transaction. |
Match the identifiers throughout the bundle. A street address can be familiar while a lot number, parking title or plan tells a different story. If a fence, garage or driveway appears inconsistent with the plan, ask whether survey evidence is needed. Neither an aerial image nor a quick measurement on a sales floor plan settles a legal boundary.
Understand what the 10.7 certificate can establish
Service NSW distinguishes the section 10.7(2) certificate from the combined (2) and (5) certificate. The former provides prescribed planning controls and constraints; the combined certificate adds relevant council-held advice. Ask whether that additional information would help with the proposed use or a particular uncertainty.
Read a planning notation as a prompt for its consequence. A flood notation might lead to questions about levels, design constraints and insurance; a heritage control might change an extension proposal. The certificate does not inspect the house or establish that every existing room and alteration was approved. Where the purchase depends on an extension or secondary dwelling, seek planning advice about that proposal before assuming it can proceed.
Separate private drains, authority assets and title rights
Sydney Water explains that a sewer service diagram records private wastewater pipes, while other documents address its assets and approval to build over or near them. Use the relevant water authority outside its area. A line on a drainage diagram and an easement on title answer related but different questions.
Put the existing and proposed footprint beside the appropriate diagrams. If a later bathroom or extension is absent from an older record, seek clarification and the relevant approvals; that discrepancy is a question, not proof of unlawful work. A diagram also does not establish pipe condition, present depth or an accurate excavation location. Those may require a plumber, authority advice and further investigation.
Give special conditions the same attention as attachments
Ask the reviewer to explain how the actual contract handles settlement timing, late completion, access, inclusions, vacant possession or a tenancy, and known defects or unapproved work. If a verbal promise matters, such as removing rubbish, repairing a leak or leaving a particular appliance, have the agreed obligation recorded appropriately. Check that any negotiated amendments appear in the version that will be exchanged.
Finance pre-approval and a deposit payment do not by themselves give you a right to withdraw if funding fails. Ask what finance or inspection protection is actually agreed, what triggers it and when it expires. With strata, have proposed or resolved levies and settlement adjustments examined alongside the scheme records. A satisfactory apartment inspection does not answer that allocation question.
Know which clock applies before exchange
NSW's contracts guidance describes the usual residential cooling-off period: five business days after exchange, ending at 5 pm on the fifth business day after the exchange day. Off-the-plan contracts generally have ten business days. Cooling off is unavailable at auction and for exchange on the same day after the property is passed in.
A 66W certificate can waive cooling off; written agreement can also change the period. If you withdraw using ordinary cooling-off rights, the usual forfeiture is 0.25% of the price. Ask your representative to confirm the actual deadline and notice requirements. Complete the checks you need before waiving protection; a signed certificate does not establish that the property, finance or inspections are satisfactory. For the wider comparison of deadlines and exceptions, see property cooling-off periods by state.
A disclosure problem needs its own legal assessment
The regulator identifies a possible 14-day rescission right for missing required documents. This is a separate issue from cooling off. Do not assume that every unsatisfactory answer, later defect or vendor-warranty allegation falls within the same right or deadline. If something appears missing or inconsistent after exchange, contact your representative immediately to assess the applicable ground, evidence, timing and notice.
A practical approach before exchange is to list each unresolved matter, the document or answer needed, who is obtaining it and the decision it affects. Some questions can be resolved by a replacement attachment; others need contract negotiation, a specialist report or a decision about accepting uncertainty. A generic request for 'all approvals' is less useful than identifying the particular rear room or garage conversion you need explained.
Check condition and approval history separately
NSW's inspection guidance explains the role and limits of pre-purchase reports. Commission the physical and specialist checks the property warrants, early enough to use the results. A contract attachment does not establish a dry roof, sound concealed frame or functioning waterproofing. Likewise, a neat renovation and a favourable visual inspection do not settle its approval history.
For later work, compare available approved drawings, consent conditions and completion documentation with what is visible. Keep documentary and physical findings separate in the decision record. A desktop read can organise those questions but cannot certify boundaries, legal rights or concealed condition. Before settlement, raise any material discrepancy found at the final inspection promptly with your representative.
Worked example: the advertised third bedroom
Illustrative reasoning example, not an inspected property. A house is advertised with three bedrooms. One is a converted garage, while the available drainage and planning papers do not explain the conversion. The room looks finished and dry. Those observations establish its current presentation, not its lawful use, structural scope or service history.
Tell the legal reviewer that using this room as a bedroom is central to the purchase. Seek the relevant approval records and have its physical condition assessed within an agreed scope. Depending on the results, the next step might be clarification, specialist advice or a negotiated term. Neither 'the contract exists' nor 'the inspector liked the room' resolves both questions.
Frequently asked questions
What documents must be attached to a contract for sale in NSW?
The applicable bundle includes title, planning, drainage and relevant title dealings and notices. Strata, pools and off-the-plan sales can need additional material. Have your representative check the property-specific requirements against the complete contract.
What is a section 10.7 certificate?
A council planning certificate containing prescribed controls and constraints affecting the land. A combined (2) and (5) certificate includes additional advice. It does not inspect the building or prove approval of every existing alteration.
Is there a cooling-off period when buying in NSW?
Usually five business days after exchange for residential purchases, or ten for off-the-plan contracts. Auction and same-day post-pass-in purchases are excluded, and a waiver or written agreement may change the position. Confirm the actual deadline with your representative.
What is a section 66W certificate?
A certificate used to waive cooling-off protection, given through the appropriate legal process. It does not confirm the building, finance or disclosure is satisfactory. Obtain advice before providing it.
Can I get out if disclosure documents are missing?
Missing required documents may create a 14-day rescission right. Its applicability, notice requirements and other potential rights need immediate legal assessment. Do not treat all disclosure or warranty problems as one rule.
Does the contract tell me the building is sound?
No. Contract review, physical inspection and approval-history enquiries answer different questions. Use the findings together before committing.
Does the sewer diagram prove an extension was approved?
No. Compare the appropriate drainage records with building and authority approvals. A diagram has a particular purpose and may not reflect later changes or current pipe condition.
Should I rely on an agent’s promise about repairs?
Ask your representative to record any material agreed obligation in the contract and confirm it appears in the exchanged version.
What should I ask if the purchase depends on a future extension?
Ask a planning professional about the intended proposal and have title restrictions, services and relevant controls reviewed. Existing zoning alone does not guarantee that design will be approved.
How this guide was researched
We read the contract through the buyer’s intended use, distinguish documentary disclosure from physical evidence and keep cooling-off and disclosure remedies separate.
Limits: This is NSW legal orientation. A licensed conveyancer or Australian legal practitioner should review amendments and certificates.
