Adjudication Enforcement

A Determination Is Only as Good as Its Enforcement

Winning an adjudication under the Building Industry Fairness (Security of Payment) Act 2017 (Qld) (the BIF Act) is not the same as being paid. The determination creates an obligation on the respondent to pay the adjudicated amount within five business days, but some respondents refuse, delay, or simply cannot pay. The BIF Act answers this with a powerful enforcement mechanism: the determination can be converted into a judgment debt of a court and enforced with the full range of execution remedies, without re-arguing the merits of the dispute. Equally, for respondents facing a defective determination, the Act and the general law preserve a narrow right to have the determination set aside. Our dual-qualified engineer-lawyers act on both sides of this equation: enforcing determinations swiftly for claimants, and challenging void determinations for respondents.

Equivalent security of payment legislation in other states and territories provides similar enforcement mechanisms, though the procedures and court rules differ. This page focuses on the Queensland framework. For the earlier stages of the process, see our guides to adjudication and adjudication timeframes.

The Interim Binding Nature of Determinations

An adjudicator's determination is interim binding. It is enforceable immediately, but it does not finally determine the parties' rights: either party may later pursue final resolution of the underlying dispute through litigation or arbitration, and amounts paid under a determination may be adjusted or recovered in those proceedings. The practical effect, however, is profound. Money flows to the successful party now, and the burden of prosecuting final proceedings falls on the party who lost the adjudication.

This "pay now, argue later" architecture is deliberate. Parliament intended to preserve cash flow through the contracting chain and to prevent deeper-pocketed parties from using delay as a weapon. Courts respect that intention, and respondents who hope to avoid payment simply by threatening future litigation quickly discover that the enforcement machinery does not wait for the final dispute to be resolved.

Obtaining an Adjudication Certificate

The first enforcement step is administrative. If the adjudicated amount remains unpaid after the statutory payment period, the claimant may apply to the Adjudication Registry for an adjudication certificate. The certificate states the adjudicated amount and is accompanied by the adjudicator's determination. Obtaining the certificate is generally straightforward and fast, provided the determination is valid and the payment period has expired.

We manage the certificate application as a matter of course in every successful adjudication where payment is not made, because speed matters at the enforcement stage. A respondent who is stalling payment is often a respondent whose financial position is deteriorating, and every day of delay increases the risk that there will be nothing left to recover.

Filing in Court as a Judgment Debt

The adjudication certificate may then be filed in a court of competent jurisdiction, as permitted by the legislation, where it is registered as a judgment debt. This step transforms the determination into an enforceable order of the court without any re-hearing of the merits. The court does not re-examine whether the adjudicator was right; the certificate is registered as a judgment for the adjudicated amount, and the ordinary machinery of civil enforcement becomes available.

The respondent may apply to set aside the registration, but only on the narrow grounds discussed below, principally jurisdictional error or breach of natural justice. The court will not revisit the adjudicator's factual findings or legal reasoning. This makes registration a formidable enforcement tool: within weeks of an unpaid determination, the claimant can hold a court judgment for the full adjudicated amount.

Execution Remedies: Garnishees, Charging Orders and Writs

Once registered as a judgment debt, the full suite of execution remedies is available. Garnishee orders direct third parties who owe money to the respondent, such as banks holding the respondent's accounts or principals owing progress payments, to pay the judgment creditor directly. Garnishee orders against project cash flow are particularly effective in construction, where the respondent is often owed substantial sums up the contractual chain.

Charging orders secure the judgment against the respondent's real property or other assets, and writs of execution authorise seizure and sale of the respondent's property. Each remedy has its own procedural requirements and strategic considerations, and the right choice depends on the respondent's asset position. Because our lawyers understand construction businesses, we target enforcement at the assets and cash flows that will actually produce payment, rather than pursuing remedies that look impressive but recover nothing.

Winding-Up Proceedings

Where the respondent is a company and the judgment debt remains unpaid, the claimant may consider insolvency action, including a statutory demand and, ultimately, an application to wind up the respondent company. An unpaid judgment debt provides powerful evidence of insolvency, and the prospect of winding-up proceedings concentrates the minds of recalcitrant respondents like little else. Many adjudicated amounts are paid promptly once insolvency action is threatened credibly.

Winding-up is a serious step with significant strategic and commercial implications, and it is not appropriate in every case. We advise on the full enforcement picture: the respondent's solvency, the likely recovery under each option, the costs involved (see our guide to adjudication costs), and the commercial relationship between the parties. Enforcement is a means to payment, not an end in itself, and the strategy is always calibrated to maximise actual recovery.

The Flip Side: Setting Aside Determinations

For respondents, the enforcement machinery is formidable but not unchallengeable. A determination may be set aside by the Supreme Court on two principal grounds: jurisdictional error and breach of natural justice. Jurisdictional error occurs where the adjudicator acted beyond their authority: determining a matter not referred to adjudication, making a determination on an invalid payment claim that did not comply with section 75 of the BIF Act, determining an application lodged out of time, or considering material or arguments outside the boundaries fixed by the payment claim and payment schedule.

Breach of natural justice arises where the adjudicator denied a party a reasonable opportunity to present its case, for example by determining the dispute on a basis that neither party had advanced and on which the parties had no opportunity to be heard. These grounds are deliberately narrow. Courts consistently hold that a determination will not be set aside merely because the adjudicator made an error of fact or law within jurisdiction; the error must go to the adjudicator's authority to decide at all. This high threshold protects the speed and finality-for-now character of adjudication, and it means challenges must be framed with precision from the outset.

Strategy on Both Sides of Enforcement

For claimants, the enforcement phase rewards speed and preparation. Move for the adjudication certificate the day the payment period expires, investigate the respondent's asset position early, and select execution remedies that target real cash flow. Be alert to applications to set aside, and ensure the determination can withstand scrutiny: the best enforcement defence is a jurisdictionally sound adjudication, which is why the quality of the original adjudication application matters so much.

For respondents, the window for action is narrow. If a determination suffers from genuine jurisdictional error or a breach of natural justice, an application to set aside must be prepared promptly and argued with rigour, because courts will not rescue a respondent from a merely unfavourable determination. Where no valid ground exists, the pragmatic course is usually to pay, preserve cash flow arguments for final proceedings, and recover overpayments later if the underlying dispute justifies it. We give candid advice on which course the circumstances support, as we do for respondents at the response stage.

Frequently Asked Questions About Adjudication Enforcement

What can I do if the respondent refuses to pay an adjudication determination? Apply to the Adjudication Registry for an adjudication certificate, file it in court for registration as a judgment debt, and then enforce through garnishee orders, charging orders, writs of execution, or winding-up proceedings. The merits of the dispute are not re-argued; registration is generally swift.

Can an adjudication determination be appealed? There is no appeal as such. A determination is interim binding and can only be challenged by an application to the Supreme Court to set it aside for jurisdictional error or breach of natural justice. Errors of fact or law within the adjudicator's jurisdiction are not grounds for setting aside.

How long does enforcement take? Obtaining the certificate and registering it as a judgment debt can generally be achieved within weeks of the payment period expiring. Execution remedies then depend on the respondent's assets; a well-targeted garnishee order can produce payment within days of being made.

Is the adjudicated amount final? No. The determination is interim binding. Either party may pursue final resolution through litigation or arbitration, and amounts paid may be adjusted in those proceedings. But in the meantime the determination must be paid, and it can be enforced as a judgment debt.
