Unpaid Invoices: Writing an Effective Letter of Demand in Malaysia

Why Send a Letter of Demand?

When a customer or client refuses to pay an invoice despite reminders, a formal letter of demand signals that you are prepared to take legal action. It puts the debtor on notice, creates a clear paper trail and often prompts payment without the need for court proceedings.

Malaysian courts generally expect a creditor to have issued a letter of demand before commencing a writ action. Failing to do so may be raised by the defendant and could affect any award of interest or costs.

Documents to Gather Before You Write

Before drafting the letter, assemble all relevant evidence of the debt. This strengthens your position and ensures the letter is accurate.

• The original contract, agreement or purchase order
• Copies of all unpaid invoices, including invoice numbers and dates
• Delivery orders, work completion certificates or proof of services rendered
• Any correspondence acknowledging the debt or requesting time to pay
• Records of previous reminders or follow-up emails
• Bank statements showing non-receipt of payment

Having this documentation ready allows you to state the precise amount owed, reference specific invoices and respond quickly if the debtor disputes the claim.

Essential Contents of a Letter of Demand

An effective letter of demand should be clear, firm and professional. Avoid inflammatory language, but leave no ambiguity about your intention to pursue the matter.

Identification of the Parties

State the full legal names of your company and the debtor. If the debtor is a company registered under the Companies Act 2016, use its registered name and company number. Address the letter to its registered office.

Details of the Debt

Specify the total amount outstanding, broken down by invoice if there are multiple unpaid invoices. Include invoice numbers, dates and a brief description of the goods or services supplied. Reference the underlying contract or agreement.

Demand for Payment

Make a clear and unequivocal demand for payment of the full sum. State the deadline by which payment must be received. A period of seven to fourteen days is common, though this may vary depending on the circumstances and any contractual terms.

Consequence of Non-Payment

Inform the debtor that if payment is not received by the deadline, you intend to commence legal proceedings without further notice. This is not a threat but a statement of your intended course of action.

Interest Claimed

If you are entitled to interest, state this in the letter. Interest may arise from an express term in your contract or, in the absence of a contractual rate, under Section 11 of the Civil Law Act 1956, which allows the court to award interest at a rate it considers appropriate. Many commercial contracts stipulate an agreed interest rate for late payment, so check your terms.

Payment Instructions

Provide clear instructions on how payment should be made, including bank account details or other accepted methods. This removes any excuse for delay.

Interest and Statutory Limits

The interest you may claim depends on your contract. If your agreement specifies an interest rate for overdue invoices, you may claim that rate from the date payment became due. If there is no contractual provision, you may still claim interest, but the court has discretion to award it under Section 11 of the Civil Law Act 1956.

Be aware of the limitation period for bringing a claim. Under the Limitation Act 1953, an action founded on contract must generally be commenced within six years from the date the cause of action accrued. For an unpaid invoice, this is usually the date payment became due. If you delay too long, you risk losing the right to sue.

Serving the Letter of Demand

Proper service matters. Send the letter by registered post or courier with a delivery receipt to the debtor's registered or last known address. Keep a copy of the letter and proof of postage. If the debtor is a company, send the letter to its registered office as recorded with the Companies Commission of Malaysia.

You may also send a copy by email, but do not rely on email alone. Physical delivery provides stronger evidence if the matter proceeds to court.

What Happens If the Debtor Ignores the Letter?

If the debtor does not pay or respond by the deadline, you may proceed with legal action. The typical next steps are as follows.

Civil Suit for Debt Recovery

You may file a writ of summons and statement of claim in the appropriate court. Which court hears the claim depends on the amount claimed: the Magistrates' Court, the Sessions Court or the High Court, each of which has its own monetary jurisdiction set by statute.

Summary Judgment

Where the debt is clear and the debtor has no genuine defence, you may apply for summary judgment under Order 14 of the Rules of Court 2012. This allows the court to enter judgment without a full trial, significantly shortening the recovery process.

Winding-Up Proceedings

If the debtor is a company and the debt exceeds the statutory threshold, you may consider issuing a statutory demand under Section 466 of the Companies Act 2016. If the company fails to pay within 21 days, this may be used as evidence of the company's inability to pay its debts, supporting a winding-up petition. This is a serious step with significant consequences and should not be used merely as a pressure tactic for disputed debts.

Enforcement of Judgment

Obtaining a court judgment is only part of the process. If the debtor still does not pay, enforcement measures such as a writ of seizure and sale, garnishee proceedings or a judgment debtor summons may be necessary to recover the sum owed.

Practical Tips for Malaysian Businesses

Act promptly. The longer a debt remains unpaid, the harder it may be to recover. Debtors may become insolvent, dispose of assets or simply disappear.

Review your contracts. Clear payment terms, interest clauses and dispute resolution provisions make debt recovery more straightforward. Include a clause entitling you to recover collection costs where permitted.

Keep thorough records. Good documentation of invoices, deliveries and correspondence strengthens your position at every stage.

Consider the commercial relationship. A letter of demand may end a business relationship. In some cases, a final informal approach before issuing the letter may preserve a valuable customer while still making clear that legal action will follow if necessary.

Common questions

Is a letter of demand legally required before suing for an unpaid invoice?

It is not strictly mandatory, but Malaysian courts expect creditors to issue one before filing suit. Skipping this step may affect your claim for interest or costs.

How long should I give the debtor to pay?

Seven to fourteen days is typical. Your contract may specify a different period. The deadline should be reasonable given the amount and circumstances.

Can I claim interest on unpaid invoices?

Yes. If your contract specifies an interest rate, that rate applies. Otherwise, the court may award interest under Section 11 of the Civil Law Act 1956.

What is the time limit for suing on an unpaid invoice in Malaysia?

Under the Limitation Act 1953, you generally have six years from the date payment was due to file a claim. After that, your right to sue may be barred.

Can I wind up a company that owes me money?

Possibly. If the debt exceeds the statutory threshold and is undisputed, a statutory demand under the Companies Act 2016 may lead to winding-up proceedings if unpaid within 21 days.
