Debt Recovery Letter: How to Write a Demand Letter for Money Owed (Australia)

You need a debt recovery letter, or a demand letter for money owed. A client hasn’t paid an invoice, a customer bounced a payment, a mate borrowed money and went quiet, or a business owes you for goods you delivered months ago. You’ve sent reminders. Now you want something with teeth.

Here’s the good news: a formal demand letter is the single highest-return action in debt recovery. It costs almost nothing, it takes 15 minutes, and it gets a large share of debts paid without any further action. Here’s how to make yours one that works.

Why demand letters work

Debtors ignore reminders because reminders have no consequence. A demand letter changes the calculation: it tells the debtor precisely what happens on a specific date if they don’t pay, and it makes clear that you know the law. It also creates a paper trail that a tribunal, court or debt collector will rely on, and in most jurisdictions it lets you claim interest and costs from the date of the letter.

What your demand letter must contain

• The parties. Exact legal names. For a company, the ACN. For a sole trader, their personal name and trading name.
• The debt. Invoice numbers, dates, amounts, what was supplied, when payment was due, and what has already been paid.
• The legal basis. Breach of contract, or for goods and services a claim under the contract and the Australian Consumer Law. For construction work, your state’s security of payment Act, which has fast, powerful adjudication. For a loan, the loan agreement or, if verbal, the evidence of the loan.
• Interest. Only if the contract provides for it, or at the court’s prescribed rate once proceedings start. Templates that demand “10 per cent interest” without a contractual basis undermine your credibility.
• A deadline. 7 or 14 days.
• The consequence. Tribunal or court proceedings, a statutory demand under section 459E of the Corporations Act 2001 for company debts of $4,000 or more, or referral to a collection agency with costs added.
• Payment details and a statement that the letter is a final opportunity to resolve the matter without formal proceedings.

The escalation ladder

1. Friendly reminder (you have probably done this).
2. Letter of demand: the formal, law-cited letter described above.
3. Final demand: shorter, harder, 7-day deadline, proceedings already prepared.
4. Statutory demand (companies only): 21 days to pay or the company is presumed insolvent. This is the nuclear option and extraordinarily effective.
5. Tribunal or court claim, then enforcement.

What if it’s a friend, family member or ex?

Personal loans are enforceable contracts, even verbal ones, as long as you can show the money was a loan and not a gift. Bank transfers, messages (“I’ll pay you back by March”) and witnesses all count. The demand letter should be firm but not hostile: it sets out the loan, the evidence, the amount and the deadline, and makes clear you will file in the tribunal if it isn’t repaid. Many people find that a formal letter, rather than another awkward text, is what finally gets a straight answer.

Mistakes that make debtors ignore you

Wrong entity name. No legal basis stated. Threatening things you can’t do (police, “blacklisting”, criminal charges). Demanding interest or costs you’re not entitled to. Rambling. No deadline. Every one of these tells the debtor you’re bluffing, and a debtor who thinks you’re bluffing doesn’t pay.
