How adjudication works in Northern Territory
In the NT, adjudication runs on the West Coast model: a payment dispute arises when your claim under the contract is rejected or unpaid at the due date, and either party may apply to a registered adjudicator within 90 days. There is no payment claim / payment schedule exchange: the dispute and the deadline are the whole mechanism.
Northern Territory's regime, in 90 seconds
The sequence
First, a valid claim under your contract. Then the dispute: rejection, or the due date passing unpaid. From that moment the 90-day window runs. The application goes to a registered adjudicator or prescribed appointer, the builder responds, and the adjudicator determines the dispute, typically on the papers.
Ninety days sounds generous. It disappears fast when you're chasing payment informally, and a dispute older than 90 days is usually confined to contractual remedies or court. Diarise it the day the due date passes.
What wins at adjudication
Adjudicators decide quickly and on the documents. The winning inputs are boring: a claim that identifies the work and the amount, served on time to the right party; contemporaneous records (site diaries, notices, delivery dockets, emails anchoring dates); and a claimed amount built up transparently.
Most of that is decided months earlier, on site, by habit. The subbies who win at adjudication are the ones whose paperwork was already in order when the dispute started.
Where to apply
Registered adjudicators / prescribed appointers (via NT Government). West Coast model: 90 days from the payment dispute arising to apply.
Exact deadlines and application mechanics should be verified against the Act and current guidance before filing. They're strict, and a defective application wastes the strongest lever you have.

NT determinations are designed to be fast once the application is in; the long pole is the 90-day window to apply, which is generous but strict.
No. The regime was designed for parties to run themselves, and many subcontractors do. For larger or messier disputes a construction lawyer's review of the application is cheap insurance. Either way, the evidence that decides it is the paperwork you kept on site.
General information for Australian subcontractors, not legal advice. Statutory deadlines change and have exceptions. Verify against the Act and current guidance, or with a construction lawyer, before acting on them.
