Urgent line (02) 8111 6666A statutory demand starts a clock that cannot be paused or extended. If one has arrived, the most important thing to understand is what the 21 days actually mean.

A statutory demand is a formal written demand for a company debt of at least $4,000 (Corporations Act s 9). You have 21 days from service to pay it, reach an agreement, or apply to the court to set it aside (ss 459E, 459G). If none of those happen, the company is presumed insolvent, and the creditor can apply to wind it up. The deadline cannot be extended, even by agreement — this is the single most consequential fact on this page.
A statutory demand is a specific creditor tool under the Corporations Act (s 459E). It requires a debt, or debts aggregating, of at least the statutory minimum, currently due and payable. It is not a letter of demand, not a debt collection notice, and not a court judgment. It is a formal step whose purpose is to create a presumption of insolvency if it is not satisfied.
For it to be valid it must be for a debt of at least $4,000, be in the prescribed form — Form 509H — specify the debt and its amount, be accompanied by an affidavit verifying the debt unless it is a judgment debt, and be served on the company's registered office in accordance with s 109X.
Defects matter. A demand with a genuine defect may be able to be set aside — but only within the 21 days, and only by application to the court.
The clock starts on service, not on the date printed on the document, and not when you happened to open it. Service is effected by leaving the demand at, or posting it to, the registered office (s 109X(1)(a)). Where it is served personally or electronically with consent, that day is day zero and the 21 days run from the next day. Where it is posted, service is deemed to occur on the seventh business day after posting unless the contrary is proved (Acts Interpretation Act 1901 s 29, read with Australia Post delivery standards). Establishing the posting date precisely is therefore the first thing to do.
It cannot be extended. Not by the creditor agreeing, not by negotiations being underway, not by you being on leave. The court has no jurisdiction to extend the time to file and serve an application to set a demand aside (David Grant & Co v Westpac (1995) 184 CLR 265).
This has a practical consequence directors get wrong constantly: a creditor telling you "we're happy to talk" does not stop the clock. Unless the demand is formally withdrawn or the debt is paid, day 21 arrives regardless of how the conversation is going.
If the demand is unsatisfied, the company is presumed insolvent (s 459C). The creditor can then apply to the court to wind it up, and the presumption makes that application substantially harder to resist. Raising grounds you could have raised in a set-aside application needs the court's leave (s 459S), and proving solvency takes audited, contemporaneous cash flow and balance sheet evidence rather than assertion.
Consequences follow quickly from there. Once a wind-up application is filed it is usually advertised, which is when banks and other creditors find out. Facilities get reviewed. Suppliers tighten terms. And critically, the restructuring options that were available on day 1 may no longer be practical.
If a statutory demand has been served, the date of service is the most important fact in your business right now — establish it precisely today. If the debt is disputed, you need a lawyer this week, not next. If it is genuinely owed and unpayable, the 21 days are the last part of this process where you still have a choice about what happens to the company. Either way, the worst available option is to negotiate informally and let the clock run out.
