Understanding Instalment Contracts in Queensland Property Transactions
Kale Venz
In the dynamic landscape of Queensland property, certainty and clarity are paramount. While most residential property contracts proceed smoothly from signing to settlement, there lies a subtle legal nuance that can dramatically alter the rights and obligations of both buyers and sellers: the instalment contract. Often unintentionally created, instalment contracts grant buyers several statutory protections in the case of a buyer’s default, which restrict a seller’s right to deal with the contract.
What is an Instalment Contract?
Under section 71 of the Property Law Act 1974 (Qld), an instalment contract is broadly defined as an executory contract for the sale of land where the purchaser is bound to make one or more payments (other than a deposit) without becoming entitled to receive a conveyance (transfer of title) in exchange for those payments. In essence, it's a contract where the buyer makes payments to the seller, which do not form part of the deposit over time before the property formally changes hands at settlement.
The 10% Threshold and Beyond: A Critical Trigger
The term "deposit" itself has a specific meaning within the Property Law Act. The Act provides that a deposit cannot exceed 10% of the purchase price (or 20% for off-the-plan sales). Where the deposit exceeds the prescribed percentage of the purchase price, the contract will be deemed to be an instalment contract, regardless of the intentions of the parties. A contract may also fall within the meaning of an instalment contract in the following circumstances:
- Additional Pre-Settlement Payments: Payments such as license fees, early possession fees, or any other amounts paid by the buyer to the seller before settlement, and separate from the deposit, can inadvertently trigger an instalment contract. Even a seemingly small, non-deposit payment can convert a standard contract into an instalment contract.
- Non-Refundable Deposits: While less common in standard contracts, if a deposit is structured to be non-refundable, particularly if released to the seller, it can be re-characterised as an instalment, thereby triggering the Act's provisions.
The Unexpected Consequences: Why Sellers Must Beware
For sellers, the inadvertent creation of an instalment contract introduces a suite of statutory protections for the buyer. It is important to be aware of these protections as they restrict how a seller may deal with a buyer’s default of the contract. These protections include:
- Restricted Termination Rights (Section 72 PLA): Unlike standard contracts, a seller cannot immediately terminate for a buyer's default under an instalment contract. The seller must provide the buyer with at least 30 days' written notice to remedy the breach before the seller may exercise a right of termination. The inability to immediately terminate an instalment contract will often have lasting delays from a seller who may be unable to enter into a subsequent contract, even where it is abundantly clear the buyer will be unable to complete the contract.
- Buyer's Right to Lodge a Caveat (Section 74 PLA): Under an instalment contract, the buyer gains an express statutory right to lodge a non-lapsing caveat over the property. This caveat prevents the registration of any other instrument affecting the title of the property until it is removed, potentially complicating any dealings with the land.
- Buyer's Right to Demand Conveyance (Section 75 PLA): Perhaps most impactful, if the buyer has paid one-third or more of the purchase price (and is not in default), the buyer can demand by written notice that the seller transfer the legal title to them immediately. It is however, a condition of the transfer that the seller be permitted to execute a mortgage over the property in favour of the seller for the remaining balance of the purchase price. This transforms the seller into a mortgagee and imputes the seller with all the associated risks and responsibilities as mortgagee of the property.
- Deposit of Title Deeds (Section 76 PLA): A purchaser can also require the vendor to deposit a duly executed transfer document with a prescribed authority (such as a solicitor) to be held in trust until the time for performance of the contract arrives, the contract is discharged by performance or otherwise, or upon an order of the court.
Protecting Your Position
The statutory protections imposed for the benefit of a buyer under an instalment contract can be significant for sellers, and may impact a seller’s financial liquidity, control over their property, and ability to enter into subsequent contracts following a buyer’s default. Unfortunately, it is often the case that instalment contracts are inadvertently entered into, and the statutory protections are enlivened without the knowledge or intent of either the buyer or seller.
To avoid creating an instalment contract, particular care must be taken with:
- ensuring a deposit and any associated payments do not exceed the prescribed percentage of 10% (20% for off-the-plan purchases) of the purchase price;
- any agreements for additional payments under a contract prior to settlement, such as license fees or early possession payments, are separate from the contract;
- accepting non-refundable payments from a buyer when agreeing to extensions to critical dates in the contract that do not entitle the buyer to receive conveyance of the property.
Before entering into any contract for the sale or purchase of residential property, we recommend seeking legal advice to ensure that you are not unknowingly entering into an instalment contract.

Preparing a Contract for Sale of Land in NSW is a critical step in any property transaction. For vendors, the contract sets the legal framework for the sale and defines the rights and obligations once contracts are exchanged. Errors or omissions at this stage can expose a vendor to issues such as delays and disputes. In NSW, a property cannot be marketed for sale without a draft Contract for Sale. The contract must include prescribed documents, also known as vendor disclosure documents. These include: a current title search; a plan of the land; relevant dealings affecting the land; a Council Planning (section 10.7) Certificate; and a sewerage diagram. Depending on the property, additional documents may be required, such as strata records, pool compliance or non-compliance certificate or notices affecting use or development. The consequences of missing disclosure documents can be significant. A purchaser may have a statutory right to rescind the contract within 14 days after exchange if certain prescribed documents are not included, which can result in a sale being terminated even where price and key terms have been agreed. It is also important that proper special conditions are drafted. These can address things such as potential property issues, manage tenancy arrangements and tailor settlement terms. Poorly drafted or missing conditions often lead to disputes, which can cause delays in settlement, prompt renegotiation or allow the purchaser to rescind the contract. Timing is also important. Preparing the contract early allows potential issues to be identified before a property is listed. This reduces pressure during negotiations and helps avoid last minute amendments that can unsettle a transaction or lead to a purchaser withdrawing. CJM Lawyers assists vendors across NSW with the preparation of Contracts for Sale of Land, ensuring that disclosure obligations are met and that the contract accurately reflects the property and the vendor’s position. We provide practical advice on risk management, special conditions and settlement planning. A well prepared contract is the foundation of a smooth property sale. Early legal advice can reduce risk, protect value and support a timely settlement. If you would like advice on preparing a Contract for Sale, contact the CJM Lawyers NSW property team.

You’ve served your payment schedule disputing a construction payment claim. Now the claimant has applied for adjudication. What happens next? Many respondents enter the adjudication process unprepared, not realising how quickly decisions are made or how binding they are. Understanding the adjudication process under Queensland’s Building Industry Fairness (Security of Payment) Act 2017 and NSW’s Building and Construction Industry Security of Payment Act 1999 is critical to protecting your interests. What Is Adjudication? Adjudication is a fast-track dispute resolution process designed to provide interim cash flow relief while preserving parties’ rights to pursue final resolution through court or arbitration. An independent adjudicator reviews the payment claim, payment schedule, and supporting materials, then makes a binding determination on how much must be paid. The key word is interim. The adjudicator’s decision determines payment obligations temporarily, not permanently. However, most disputes end at adjudication – the cost and delay of further litigation means parties often accept the determination as final. The Timeline: Speed Is Everything Adjudication moves fast. Once an application is made: Queensland : You typically have 10 business days to file your adjudication response. The adjudicator then has 15 business days to make a determination (extendable to 20 days with consent). New South Wales: You have 5 business days to file your response (extendable to 10 days with claimant consent). The adjudicator has 10 business days to decide (extendable to 15 days). These timeframes are strictly enforced. Late submissions may be rejected entirely, leaving you unable to present your case. What goes into an Adjudication Response? Your adjudication response is your opportunity to defend your position. It must be comprehensive because you’re limited to the reasons you included in your payment schedule – no new arguments are permitted. A strong response typically includes: Detailed submissions: Explaining why the scheduled amount is correct, addressing each element of the claim Supporting evidence: Contracts, correspondence, site records, photographs, expert reports, invoices Legal analysis: Interpretation of contract terms, legislative requirements, and relevant case law Technical challenges: Jurisdictional objections, validity issues with the claim or adjudication application This is not a simple letter. Adjudication responses regularly run 30–50 pages with extensive annexures. The adjudicator will be reviewing both parties’ submissions simultaneously, so clarity and organisation matter. The Adjudicator’s Decision The adjudicator will issue a written determination setting out their decision and reasons. They can: Uphold the claimed amount in full Accept your scheduled amount Determine a different amount between the two In both Queensland and NSW, you must pay the adjudicated amount within 5 business days (or as specified in the determination). Failure to pay can result in the claimant suspending work or, more seriously, obtaining a judgment for the debt and pursuing enforcement action against your company. Can You Challenge the Decision? Yes, but the grounds are narrow. You can apply to court to set aside an adjudication determination for: Jurisdictional error: The adjudicator made a decision they had no power to make Denial of natural justice: You weren’t given a fair opportunity to present your case Generally, you cannot challenge the adjudicator’s decision simply because you disagree with their assessment of the facts or law. The threshold for setting aside a determination is high. Importantly, you must still pay the adjudicated amount even while challenging the determination. The principle is “pay now, argue later.” The Importance of Early Preparation The adjudication timeframes are tight. Once you serve a payment schedule disputing a claim, you should assume adjudication is coming and start preparing immediately: Waiting until the adjudication application arrives leaves you scrambling. In NSW, with only 5 business days to respond, delay can be fatal to your case. Get Legal Guidance Adjudication is a high-pressure, time-critical process that requires immediate action and strategic thinking. Whether you’re facing an adjudication application or considering applying for one yourself, experienced legal advice makes the difference between success and failure. CJM Lawyers’ litigation and dispute resolution team regularly represents clients in security of payment adjudications across Queensland and NSW. We understand what adjudicators look for, how to present your case effectively, and how to protect your interests under tight deadlines. Don’t navigate adjudication alone – contact CJM Lawyers today.

A payment claim arrives from your contractor demanding payment. Your instinct might be to set it aside while you check the details. That delay could be the most expensive mistake you make. Under Queensland’s Building Industry Fairness (Security of Payment) Act 2017 and NSW’s Building and Construction Industry Security of Payment Act 1999, you could become legally obligated to pay the full amount – even if you dispute the work – simply by failing to respond on time. What Is a Payment Claim? A payment claim is a formal written demand for payment under a construction contract. It doesn’t need to be labelled “payment claim” – an invoice or progress claim identifying the work and amount will often suffice. These claims are designed to keep cash flowing through construction projects, giving claimants a fast-track recovery process. The Danger of Doing Nothing If you don’t respond by serving a payment schedule within the prescribed timeframe, you are deemed to have admitted the claim. This means you become liable to pay the full amount – even if the work was defective or never performed. The claimant can take immediate debt recovery action, and you lose your right to dispute through adjudication. The Timeframes Are Tight Unless your contract provides otherwise, the timeframes are tight and are usually: Queensland: 15 business days from receiving the payment claim to serve a payment schedule. New South Wales: 10 business days from receiving the payment claim to serve a payment schedule. These are strict deadlines with limited discretion for extensions. The consequences of missing them are severe. What Is a Payment Schedule? A payment schedule is your formal response to the claim. It must identify the claim, state the amount you propose to pay (which can be zero), and provide reasons if you’re paying less than claimed. What Happens Next? After serving a payment schedule, the claimant can either accept your scheduled amount or apply for adjudication – a rapid process (typically 10–15 business days) where an independent adjudicator reviews the dispute. The adjudicator’s decision is binding, meaning you must pay the adjudicated amount even if you plan to challenge it later in court. Why You Need Legal Advice Now Time is not on your side. Getting legal advice immediately is essential to: Assess validity: Not every claim is valid under the legislation. A lawyer can identify defences quickly. Prepare a payment schedule: An invalid payment schedule leaves you exposed as if you hadn’t responded at all. Don’t Let the Clock Run Out Security of payment legislation protects cash flow in the construction industry, but it places significant responsibility on you to respond quickly and correctly. The penalty for getting it wrong is severe. Our experienced litigation team regularly assists clients with security of payment disputes across Queensland and NSW. We can review your claim, prepare a compliant payment schedule, gather evidence, and represent you in adjudication if required. Don’t face this alone – contact CJM Lawyers today.
