Statutory Letter of Demand In Australia: What You Need to Know

When a customer or supplier doesn’t pay on time, cash flow gets squeezed and everything else becomes harder. Before you jump straight into court, the simplest next step is often a letter of demand - a clear, formal notice that the money is due and that you intend to take action if it isn’t paid.

But you may also see the phrase “statutory letter of demand” used online. In Australia, that wording can be confusing. A standard letter of demand is not a “statutory demand” under the Corporations Act (that’s a different, much more serious insolvency procedure). This guide explains what a letter of demand does, when to use one, what to include, and how to send it properly - all from a small business perspective.

With the right approach, a firm but fair letter can prompt payment, preserve relationships and keep you out of costly disputes.

What Is A Statutory Letter Of Demand (And How Is It Different To A Statutory Demand)?

In everyday business, most people use “letter of demand” to mean a formal written request for payment of an outstanding amount. It sets out what’s owed, why it’s owed, and the time you’re giving the other party to pay before you escalate.

It’s not a court document and it’s not created by statute. It’s a practical, commercial step that shows you’re serious and gives the other party a fair chance to fix the issue.

By contrast, a “statutory demand” is a specific legal device used only against companies under section 459E of the Corporations Act. If the company doesn’t comply within 21 days, it’s presumed insolvent and you can apply to wind it up. That’s a major escalation tool and carries strict drafting and service rules. It’s not the same thing as a standard letter of demand and is generally used later, when the debt is undisputed and you’re ready to pursue insolvency proceedings.

For most small business debts, you’ll start with a regular letter of demand. If you’re dealing with a clear, undisputed debt owed by a company and are considering a statutory demand, it’s best to get legal advice before taking that step.

When Should Your Business Send A Letter Of Demand?

A letter of demand is most effective when:

• You have a clear, documented debt (for example, an unpaid invoice, purchase order or service agreement).
• You have already sent at least one polite reminder and a final reminder.
• There’s no genuine dispute about the quality, quantity or timing of the goods/services.
• Your contract allows you to charge interest or reasonable recovery costs (if you plan to claim them).

In other words, it’s well-suited to straightforward non-payment. If there is a real dispute (for example, alleged defects, delays or scope issues), consider addressing the underlying breach of contract first. A demand that ignores a genuine dispute can entrench positions and make resolution harder.

It’s also useful as a record. If the matter goes further, your demand shows you tried to settle the issue informally before escalating. Courts and tribunals generally expect parties to attempt reasonable pre-action steps.

What Should A Statutory Letter Of Demand Include?

Keep it clear, factual and firm. A good letter of demand typically covers:

1) Your Details And The Debt

• Your business name, ABN and contact details.
• The debtor’s full name and address (and ABN or ACN if known).
• Invoice numbers, dates and a concise description of the goods/services.
• Total amount owing, including any interest or fees you’re entitled to claim.

2) Basis Of The Claim

• Reference to the contract or terms (e.g., date and title of your Service Agreement or Terms of Trade).
• Relevant payment clause and due date(s).
• Any prior reminders or attempts to resolve the matter.

3) What You Want And By When

• A clear demand for payment of the specified amount.
• A firm deadline (e.g., 7 or 14 days) stated in days and calendar date.
• Payment method details (bank account, reference number).

4) Consequences Of Non-Payment

• Next steps you may take (for example, engaging debt collectors, commencing proceedings, or issuing a statutory demand if appropriate for undisputed company debts).
• If your terms allow, mention interest or recovery costs you’ll seek to recover.

5) Option To Discuss

• Invite the debtor to contact you within the deadline to raise any genuine dispute or propose a payment plan.

Make your tone professional and fact-led. Avoid language that could be seen as threatening or harassing. If you intend to claim interest or late fees, ensure your contract allows it and that your approach complies with Australian Consumer Law principles. If you’re unsure, review your position against guidance on late payment fees before including them.

How Do You Send A Letter Of Demand Properly?

There’s no single mandated way to serve a standard letter of demand, but good practice improves your chances of a quick, clean resolution - and helps you prove delivery later.

Choose Your Method (And Keep Proof)

• Email to the last known accounts or contractual notice address, with read receipt enabled and a PDF attachment.
• Post to the registered office or last known physical address (ideally via express post with tracking or registered post).
• Courier delivery with a delivery confirmation.

Check your contract’s notice clause. If your terms specify how notices must be sent (e.g., by email to a certain address, or to the registered office), follow that method. If you send by email, it helps to attach the letter as a signed PDF. For context on whether and when electronic communications can bind parties, see this guide on whether an email is legally binding.

Set A Clear Deadline

State a deadline in both days and a calendar date (for example: “within 14 days, by 5pm on Friday 22 November 2025”). If your contract counts time by business days, it can be helpful to align your timeline - here’s a refresher on what a business day means in Australian contracts.

Sign And Format Correctly

Include your full name and role, and sign the letter (wet ink or e-signature) for clarity. If you’re signing on behalf of a company, make sure you have authority under the contract to issue notices. For general execution rules, these legal requirements for signing documents are a helpful reference.

Attach Supporting Evidence

Attach copies of the relevant invoices, purchase orders, delivery confirmation, timesheets or acceptance emails. This reduces back-and-forth and shows the claim is genuine and well-documented.

What Happens After You Send It?

Most debts are resolved at this stage. Typically, one of four things occurs:

1) They Pay In Full

Great outcome - send a receipt and close the loop politely. If the relationship will continue, consider reinforcing your credit terms and improving onboarding to prevent repeat issues (for example, obtaining personal guarantees, deposits, or security interests).

2) They Propose A Payment Plan

If cash flow is the genuine issue, a structured plan can be a practical solution. Put it in writing, set clear dates, and include a default clause. In some cases, a short promissory note can document the arrangement neatly. For larger or higher-risk balances, consider a Deed of Settlement with stronger enforcement terms.

3) They Dispute The Debt

Ask for their reasons and any supporting evidence. If the dispute has merit, you may need to negotiate a variation, issue a credit, or fix the underlying issue. If you settle, document the resolution in a Deed of Release and Settlement so both sides have certainty.

4) They Ignore It

If there’s no response by your deadline, you can escalate. Options include:

• Engage a third party to pursue recovery (for example, under a tailored Debt Collection Agreement).
• Commence proceedings in the appropriate court or tribunal (usually a local court, small claims division or civil and administrative tribunal, depending on the amount and your state).
• If the debtor is a company and the debt is undisputed and over the statutory minimum, consider a Corporations Act statutory demand (strict rules apply - get advice first).

When deciding, weigh the size of the debt, prospects of recovery, and costs and time involved. Sometimes, improving your pre-engagement risk controls (deposits, staged payments, tighter terms) is the smartest longer-term fix.

Common Mistakes (And How To Avoid Them)

A strong letter of demand is short, factual and aligned with your contract and the law. These are the missteps we see most often - and how to avoid them.

Over-Claiming Interest Or Fees

Only claim interest and recovery costs if your terms allow it and the amounts are reasonable and enforceable. Excessive or unclear charges can be challenged and may raise Australian Consumer Law (ACL) concerns, especially for consumer customers. If you plan to add admin or late fees, make sure your approach aligns with guidance on charging late fees.

Ignoring A Genuine Dispute

Demand letters are best for clear, undisputed debts. If the other party raises a plausible defect or delivery issue, address that properly. If you push ahead as if no dispute exists, you risk unnecessary litigation and cost. Consider whether there’s a practical fix or commercial compromise before escalating.

Vague Deadlines Or No Next Steps

Always state a clear deadline and outline what you’ll do if payment isn’t received. Ambiguity weakens your position.

Poor Documentation

If you think you might need to escalate, keep a complete record of the contract, scope, approvals, delivery proof, reminders and the demand letter. Good evidence shortens disputes and improves outcomes.

Using A One-Size-Fits-All Template

Templates can help you get started, but every debt and contract is different. Tailor the letter to the facts and your terms, and make sure it uses the correct entity names and addresses. If someone else is sending it on your behalf (e.g., your bookkeeper), provide a letter of authority to act so there’s no question about their authority to communicate demands for your business.

Overlooking Security And Risk Controls

If you often supply on credit, consider building-in protection on day one - for example, clear credit terms, personal guarantees and registering a security interest on the PPSR where appropriate. This makes recovery far easier if things go wrong. For an overview of why this matters, see our guide to the PPSR.

Step-By-Step: Drafting And Sending Your Letter

Use this simple process to keep things moving and reduce stress.

Step 1: Confirm The Facts

• Check the contract and invoice details, due dates and notice clause.
• Confirm who owes the money (correct legal entity, not just a trading name).
• Note any previous reminders and communications.

Step 2: Decide Your Ask And Your Deadline

• Full payment, or will you consider a payment plan?
• Set a realistic timeframe (7-14 days is common) and specify the calendar date.

Step 3: Draft The Letter

• Identify the parties, the debt and the contractual basis.
• State the amount owed, interest (if applicable), and where to pay.
• Outline the next steps if payment is not received by the deadline.

Step 4: Attach Evidence

• Invoices, delivery notes, emails confirming acceptance or completion.

Step 5: Sign And Send

• Sign the letter (electronic or wet-ink) and send via the notice method in your contract (or email and registered post if uncertain).
• Record the time sent, method, and delivery confirmation.

Step 6: Follow Up

• Calendar a reminder for the day after the deadline.
• If you get no response, action your escalation plan promptly.

Frequently Asked Questions

Can I send a letter of demand by email only?

Often yes, particularly if your contract allows notice by email or the parties regularly correspond via email. Include a signed PDF, request a read receipt and follow up with a posted copy to the registered office if you want extra certainty. If you rely on email communications to agree to changes or payment plans, remember the context discussed in our guide on emails being legally binding.

How long should I give them to pay?

7-14 days is common for ordinary commercial debts. Choose a timeframe that’s proportionate to the amount and your relationship. Be clear whether you’re counting calendar days or business days (see what a business day means) and include a calendar date.

Should I threaten court straight away?

It’s better to lay out your next steps calmly without aggressive language. Courts expect parties to try to resolve disputes before starting proceedings, and a measured tone often leads to faster, more cooperative outcomes.

What if the other party offers a payment plan?

Consider it if it’s realistic and protects your position. Put it in writing, include clear dates and a default clause, and consider documenting it as a promissory note or Deed of Settlement for extra certainty.

Do I need a lawyer to send a letter of demand?

You can send one yourself, but if the debt is large, disputed, or linked to ongoing commercial relationships, getting help can save time and reduce risk. A lawyer can also advise whether to escalate to a statutory demand (for undisputed company debts) or commence proceedings.

Beyond The Letter: Strengthening Your Position For Next Time

Prevention beats recovery. A few practical upgrades to your onboarding and contracting processes can dramatically cut late payments:

• Use strong Terms of Trade that clearly set payment timing, default interest and recovery costs, and incorporate them into every sale or engagement.
• For bigger jobs, use a signed Service Agreement or Customer Contract with staged payments and a robust variation process.
• Secure payment up-front or in stages, and consider holding deposits or progress claims.
• Where appropriate, register security interests on the PPSR, particularly for supply of goods on credit.
• Keep scope, delivery and acceptance documentation tight to reduce scope disputes later.
• If you resolve a dispute, finalise it in a Deed of Release and Settlement so there are no loose ends.

A clean contracting process makes letters of demand faster, simpler and more effective - and, in many cases, unnecessary.

Key Takeaways

• A standard letter of demand is a practical, pre-legal step to recover a clear, undisputed debt - it’s different to a Corporations Act “statutory demand”.
• Be clear, factual and firm: identify the parties, debt, contractual basis, deadline and the next steps you’ll take if unpaid.
• Send it in line with your contract’s notice clause, keep proof of delivery and set a clear deadline using calendar dates (or defined business days if relevant).
• If there’s a genuine dispute, address the underlying issue first - jumping straight to demands can escalate conflict and cost.
• If you agree a payment plan, document it properly (a short promissory note or settlement deed can help) and tighten your future terms and credit controls.
• Only claim interest or fees where your contract permits and ensure your approach aligns with Australian Consumer Law and guidance on late payment fees.
• For repeat credit supply, consider security on the PPSR to strengthen your position from the outset.
