Adjudication Applications

Getting Paid Starts With a Properly Prepared Application

The adjudication application is the document on which your entire recovery stands or falls. Under the Building Industry Fairness (Security of Payment) Act 2017 (Qld) (the BIF Act), adjudication is a paper-based, fast-track process in which the adjudicator determines the dispute from the written submissions and evidence before them. There is no oral hearing, no witness examination, and generally no second chance to fill gaps in your case. A poorly prepared application can see a meritorious claim reduced or rejected outright, while a well-constructed application puts maximum pressure on the respondent and gives the adjudicator a clear path to find in your favour. Our dual-qualified engineer-lawyers prepare adjudication applications that are technically precise, legally compelling, and procedurally watertight.

At Construction.Lawyer, we act for subcontractors, head contractors, suppliers, and consultants seeking to recover unpaid progress claims, variation amounts, delay costs, and retention money through adjudication. Equivalent security of payment legislation exists in New South Wales, Victoria, Western Australia, South Australia, Tasmania, the ACT, and the Northern Territory, and we advise on applications across Australia, though the guidance below focuses on the Queensland framework.

Eligibility: Can You Apply for Adjudication?

Not every unpaid invoice can be taken to adjudication. The BIF Act sets threshold requirements that must be satisfied before an application will be valid. First, there must be a construction contract as defined by the Act. A qualifying construction contract may be written, oral, or partly written and partly oral, subject to the Act; a formal signed agreement is not always required. Certain categories of work are excluded, most notably domestic building work performed for an owner-occupier where the Act does not apply.

Second, you must have served a valid payment claim complying with section 75 of the BIF Act. The payment claim must relate to a valid reference date under the contract, identify the construction work or related goods and services with sufficient particularity, state the claimed amount, and request payment. Third, a trigger event must have occurred: the respondent served a payment schedule proposing a lesser amount, the respondent failed to pay a scheduled amount by the due date, or the respondent failed to serve a payment schedule at all and did not pay the claimed amount. Each trigger event carries a different filing window, which we explain in detail in our guide to adjudication timeframes.

The Payment Claim: Foundation of the Application

Every adjudication application is built on the payment claim that preceded it. A defective payment claim will undermine everything that follows, no matter how strong the underlying entitlement. We routinely review payment claims before service to ensure they withstand scrutiny: that the reference date is valid and has not previously been used, that the work is identified with the particularity the Act demands, that the claimed amount is correctly calculated, and that service is effected on the correct party by a permitted method.

Common payment claim defects include claiming under an exhausted reference date, lumping multiple reference dates into a single claim, failing to adequately identify the construction work claimed, and serving the claim on the wrong entity or at the wrong address. These are jurisdictional defects. An adjudicator confronted with an invalid payment claim lacks the power to determine the application, and the respondent will have a strong basis to resist the claim or later apply to set aside any determination. Early review by our team eliminates these risks before they can damage your position.

Drafting the Application Under Section 79

Under section 79 of the BIF Act, the adjudication application must be in writing, made to the Adjudication Registrar, lodged within the applicable statutory timeframe, and must include the payment claim and any payment schedule, identify the disputed amount, set out the reasons the claimant is entitled to that amount, and be accompanied by the prescribed fee and all supporting documentation the claimant relies on. The application is, in substance, the claimant's entire case. New arguments and new material generally cannot be introduced later, so the drafting stage is where the outcome is largely decided.

Our drafting approach is systematic. We set out the contractual framework, identify the provisions entitling the claimant to payment, walk the adjudicator through the calculation of the claimed amount, and respond directly to every reason for withholding payment raised in the respondent's payment schedule. We present the argument in clear, logical steps because the adjudicator works under severe time pressure. An application that is easy to follow is an application that is easy to allow. Where the claim involves complex variations, prolongation costs, or quantum meruit entitlements, our engineering qualifications allow us to present the technical material in a way adjudicators can act on with confidence.

Compiling the Evidence

The adjudicator cannot visit your site or interview your workers. They can only assess the documents placed before them, which makes evidence compilation the most labour-intensive and most decisive part of preparing an application. We compile exhaustive evidentiary packages tailored to the issues in dispute, including:

Site diaries and daily reports recording labour, plant, materials, weather, and progress; dated photographs and videos substantiating work performed and site conditions; variation registers and variation submissions demonstrating the scope and pricing of changed work; extension of time claims and delay analyses supporting prolongation and time-related cost entitlements; progress reports, programmes, and meeting minutes establishing the project chronology; and correspondence evidencing instructions, approvals, and the parties' conduct. Every document is indexed, cross-referenced to the submissions, and presented so the adjudicator can verify each component of the claimed amount without hunting through disorganised material.

Common Defects That Invalidate Applications

Experience shows that applications fail most often for procedural reasons rather than on the merits. The most common fatal defects include lodging outside the applicable filing window, which is jurisdictional and cannot be cured; relying on an invalid payment claim; serving the application on the respondent incorrectly or late; failing to pay the prescribed application fee; and failing to include the material section 79 requires. An application must also be served on the respondent at the same time it is lodged with the Adjudication Registrar, and proof of service should be retained.

Beyond these threshold defects, applications are weakened by poor organisation, unsupported assertions, and a failure to engage with the respondent's reasons for withholding payment. An application that ignores the payment schedule invites the adjudicator to accept it. Our forensic review process identifies and eliminates every potential defect before lodgement, protecting claimants from procedural failure that would otherwise cost them both the filing fee and the recovery itself.

What Happens After Lodgement

Once lodged with the Adjudication Registrar, the application is referred to a registered adjudicator, generally within a matter of days. The respondent then has the opportunity to lodge an adjudication response within the applicable response period, which depends on whether the claim is treated as a standard or complex payment claim under the BIF Act. The respondent's response is generally limited to the reasons set out in their payment schedule, a constraint we examine in our guide to adjudication responses. The adjudicator must then deliver a determination within the statutory decision period, stating the adjudicated amount, the date for payment, and the apportionment of the adjudicator's fees.

Throughout this period, the adjudicator may request further information or clarification from either party. We manage these requests promptly and precisely, ensuring every response reinforces the claimant's position without opening new avenues of dispute. Once a favourable determination issues, the respondent must pay within five business days. If they do not, the determination can be enforced as a judgment debt, a process explained in our guide to adjudication enforcement.

Practical Tips for Claimants

The strongest applications are built long before a dispute crystallises. Maintain disciplined project records from day one: daily site diaries, dated photographs, contemporaneous correspondence, and a live variation register are the raw material of a successful adjudication. Ensure every variation and instruction is documented in writing, and never allow reference dates to pass unused if you are owed money. When a dispute arises, act immediately. The filing windows under the BIF Act are short and strictly enforced, and delay can extinguish your right to adjudicate altogether.

Engage experienced advisors early, ideally before the payment claim is served. The cost of early advice is modest compared with the cost of a failed application, and the fee structures involved are explained in our guide to adjudication costs. At Construction.Lawyer, we assess the merits of your claim candidly, prepare the application to the standard the process demands, and manage the matter through to determination and payment.

Frequently Asked Questions About Adjudication Applications

How long do I have to lodge an adjudication application? It depends on the trigger event. Where a payment schedule was received but the scheduled amount is disputed, the application is generally due within 30 business days after receipt of the schedule; where a scheduled amount was not paid, within 20 business days after the due date; and where no payment schedule was given and the claimed amount was not paid, within 30 business days after the later of the payment due date and the last day on which the schedule could have been given. The current Act and the actual dates must be checked before filing. See our detailed guide to adjudication timeframes.

Can I include new claims in the application that were not in the payment claim? Generally no. The application is confined to the matters raised in the payment claim. Attempting to introduce new claims risks the adjudicator declining to consider them or, worse, a successful challenge to the determination. This is why the payment claim must be drafted with care from the outset.

What documents do I need to support my application? At minimum: the contract, the payment claim, any payment schedule, and the evidence substantiating your entitlement, such as site diaries, photographs, variation registers, extension of time claims, invoices, and correspondence. The stronger and better organised your documentation, the stronger your application.

What if my application is defective? A jurisdictionally defective application may be invalid regardless of its merits, and the respondent may successfully resist it or apply to set aside any resulting determination. Some defects can be avoided by withdrawing and re-lodging where the filing window remains open, but this is not always possible. Early legal review is the safest course.
