Statutory Escrow and Deposit Custody Rules

In New South Wales, money paid as a deposit for an off-plan residential property does not go directly to the developer. Under reforms enacted via the Conveyancing Legislation (Amendment) Act 2018 (NSW), which amended the Conveyancing Act 1919 (NSW), escrow is legally mandatory for all off-plan residential contracts.

Developers are legally restricted from using buyer deposits as working capital to fund ongoing construction work. The deposit, which is capped at a maximum of 10% of the contract purchase price, must be held in a regulated trust account or a controlled money account. These accounts are managed by a neutral stakeholder, typically the real estate agent's trust account under the Property and Stock Agents Act 2002 (NSW) or the vendor's legal practitioner/conveyancer trust account under the Legal Profession Uniform Law (NSW).

NSW Fair Trading and the Law Society of New South Wales regulate the licensed entities holding these trust accounts. The funds cannot be released to the developer under any circumstances until the contract reaches final settlement, which occurs only after construction completes and individual land titles are registered.

Payment Milestone Structures in Sydney Off-Plan Contracts

Off-plan residential purchases in Sydney follow a strict two-stage statutory payment structure, which differs significantly from staged-payment custom home-building contracts.

  • Contract Exchange: The buyer pays a deposit of up to 10% of the purchase price upon exchanging contracts. This money remains locked in a trust account. Alternatively, if agreed by the developer, the buyer may supply a deposit bond or bank guarantee issued by an Australian Financial Services Licensed (AFSL) institution.
  • Final Settlement: The remaining 90% balance of the purchase price is payable in a single lump sum at settlement. Settlement takes place only after the local council or an accredited certifier issues an Occupation Certificate (OC) and the Registrar-General registers the Strata Plan or Plan of Subdivision at NSW Land Registry Services.

Buyers are not subjected to progressive milestone payments or construction stage drawdowns during the build phase for off-plan strata apartments.

Legal Remedies for Delayed Handover

Construction delays are governed by the contract's sunset clause and statutory provisions under Section 66ZS of the Conveyancing Act 1919 (NSW). The sunset clause specifies a drop-dead date by which the developer must register the strata plan and issue the Occupation Certificate.

If the developer fails to achieve registration by the contractual sunset date, the buyer holds the unconditional statutory right to rescind the contract. Rescission cancels the agreement and entitles the buyer to a full refund of their 10% deposit plus any accrued bank interest specified under the contract terms.

If the developer seeks to extend the sunset date or cancel the contract due to delays, they cannot do so unilaterally. Under Section 66ZS, a developer can only rescind an off-plan contract if they obtain the buyer's explicit written consent or secure an order from the Supreme Court of New South Wales. The Supreme Court will only grant such an order if the developer proves that rescission is just and equitable in the circumstances.

Deposit Protection in the Event of Developer Insolvency

Because the deposit is legally isolated in a licensed trust account, it does not form part of the developer's corporate asset pool. If the developer enters administration, liquidation, or receivership during construction, the funds remain secured.

In the event of developer insolvency, the off-plan contract typically terminates or becomes unenforceable due to the developer's failure to complete the project before the sunset date. The stakeholder holding the trust account is legally obligated to return the full deposit amount directly to the buyer.

If the stakeholder wrongfully refuses or fails to release the trust funds, buyers are protected by the Statutory Compensation Fund managed by NSW Fair Trading under the Property and Stock Agents Act 2002 (NSW), which indemnifies consumers against money misapplied by licensed real estate agents or conveyancers.

Official Registries to Verify Sydney Projects

Before entering an off-plan contract, buyers can verify the approval status, construction records, and builder ratings of a Sydney project using statutory state databases:

  • NSW Planning Portal Spatial Viewer: Managed by the Department of Planning, Housing and Infrastructure, this registry allows buyers to verify whether a Development Application (DA) or State Significant Development approval has been granted by the local council or planning panel.
  • NSW Fair Trading Public Register: Allows buyers to check the license status and disciplinary history of the builder, developer, or licensed real estate agency.
  • iTIRS / NSW Strata Building Bond and Inspections Scheme (SBBIS): Governed by the Building Commission NSW, this platform registers apartment developments subject to the 2% strata building bond, designed to rectify structural defects identified post-completion.
  • iREMS / DecarboniSE Ratings (iComply): The NSW Building Commissioner publishes ratings under the Independent Developer Rating System (iCRES) using the star-rating platform Rating System for Developers and Builders (iCONSTRUCT/iTIRS), allowing buyers to view risk profiles of developers.

Common questions

Is a developer allowed to spend my deposit on construction costs in Sydney?
No, developers in New South Wales are strictly prohibited from using buyer deposits to fund construction. Under the Conveyancing Act 1919 (NSW), the deposit must be held in a regulated trust or controlled money account until final property settlement.
What is the maximum deposit a developer can ask for off-plan?
The maximum deposit a developer can request for an off-plan residential contract in NSW is 10% of the total purchase price. This money is held securely by an authorized stakeholder until settlement.
Can a developer cancel my contract if property values rise during construction?
No, developers cannot unilaterally cancel your contract to resell at a higher price. Under Section 66ZS of the Conveyancing Act 1919 (NSW), a developer can only terminate under a sunset clause if you give written consent or if they obtain an order from the Supreme Court of NSW.
What happens to my money if the builder goes bankrupt before finishing?
Your deposit remains secure in a licensed trust account separate from the builder's assets. If the project cannot be completed, the contract is rescinded and your deposit is refunded in full.
Where can I check if a Sydney development project has legal approval?
You can verify development approvals through the NSW Planning Portal Spatial Viewer managed by the Department of Planning, Housing and Infrastructure, and check builder licenses on the NSW Fair Trading Public Register.
