When (and how) to send a letter of demand: a Queensland creditor's guide.

Most unpaid invoices are recovered without ever filing in court — provided the letter of demand is drafted correctly and sent at the right moment. Here is the framework we use.

In short

Send a letter of demand once an invoice is clearly overdue and internal follow-up has not worked. A properly drafted demand sets out the debt, the basis, the deadline and the consequences of non-payment. Most debtors pay within the deadline once a solicitor's letterhead is involved. If they do not, the same letter becomes the foundation for court proceedings and a claim for legal costs. Avoid threats you would not follow through on and any language that could amount to harassment.

A letter of demand is the cheapest, fastest and most often successful step in commercial debt recovery. It costs less than a single court filing fee. It usually produces payment within 14 to 21 days. And if it does not, it becomes the foundation for the proceedings that follow.

But a letter of demand is only as effective as it is drafted. A sharply worded email from a frustrated business owner is not a letter of demand. Here is what one looks like, and when to send it.

When to escalate to a letter of demand

We generally recommend a letter of demand once all of the following are true:

  • The invoice is clearly overdue under its stated terms (often 30 days from issue).
  • You have attempted at least two internal follow-ups, including one in writing.
  • The debtor has either gone silent, made promises and not kept them, or raised a dispute that does not have substance.
  • The amount in dispute is large enough to justify the cost of escalation — usually $1,000+ for business debts.

What a good letter of demand contains

  • Clear identification of the creditor and debtor (correct legal names and entity types).
  • A short statement of the debt — invoice numbers, dates and amounts.
  • The legal basis: a contract, terms of trade, or services rendered.
  • A deadline for payment (typically 14 days from the date of the letter).
  • A clear statement of the consequences of non-payment — proceedings for the debt, interest, and costs.
  • Payment details and a contact name for queries.

What a good letter of demand does NOT contain

  • Threats of criminal action (debt is generally a civil matter — threatening criminal consequences for a civil debt may amount to misconduct).
  • Statements that could harass, intimidate or mislead the debtor.
  • Inflated amounts, fictitious 'collection fees' or other charges with no contractual basis.
  • Deadlines you have no intention of following up on. An empty threat undermines every demand you send afterwards.

What happens if they ignore it?

If the deadline passes without payment or a substantive response, we typically have the following options depending on the debtor and the amount:

  • Commence proceedings in the appropriate Queensland court (Magistrates for ≤$150,000, District for $150,000 to $750,000, Supreme above).
  • For debts against companies of $4,000+, consider issuing a Creditor's Statutory Demand under s 459E of the Corporations Act — a powerful tool but only appropriate for undisputed debts.
  • For debts against individuals of $10,000+ where you already hold a judgment, consider a bankruptcy notice.

Frequently asked

Common questions on this topic.

How long should I give a debtor to pay in a letter of demand?

Fourteen days from the date of the letter is the most common period and is generally considered reasonable. Shorter periods (seven days) are appropriate for clearly overdue debts where the debtor has already had multiple opportunities to pay. Longer periods are sometimes justified for genuinely complex disputes.

Can I send my own letter of demand or do I need a lawyer?

You can send your own — and for very small debts that may be the most economical option. But debtors take a solicitor's letterhead more seriously, and a poorly drafted self-sent demand can undermine later proceedings. Most commercial recoveries justify the small cost of a solicitor's letter.

Can I claim interest on an overdue invoice?

Yes, if your contract or terms of trade provide for it (the common rate is 10% per annum or RBA cash rate plus 6%). If your contract is silent, you can usually claim interest under the Civil Proceedings Act 2011 (Qld) from the date proceedings are commenced.

What if the debtor disputes the debt?

Assess the dispute on its merits. A genuine dispute is best resolved early through negotiation or mediation — proceeding to court on a contested debt is expensive. A manufactured dispute can usually be progressed without significant delay, as the court will see through it quickly.
