How to write a letter of demand in South Africa

What a letter of demand is

A letter of demand is a formal written notice that states what someone owes you or must do, and gives them a firm deadline to put it right before you take further action. It works on two levels. Practically, it signals that you're serious and organised — most disputes settle at this stage because the other side would rather pay than escalate. Legally, it creates a dated record that you gave fair warning, which matters if the matter later reaches an ombud or a court.

You don't need to be a lawyer to send one, and it doesn't need archaic legal language. What it needs is to be clear, factual, specific and dated.

When to send one

A letter of demand is the right tool whenever a reasonable request has already failed and you need to formalise it. Common examples:

• Money owed — an unpaid invoice, a loan, a deposit, or a refund you're entitled to.
• A consumer complaint against a bank, insurer, retailer, network or medical scheme.
• A landlord withholding a deposit or refusing to do repairs.
• An employer who hasn't paid your salary, overtime or final pay.
• A service that was paid for but never properly delivered.

LetterUp has dedicated flows for each of these — for example a refund demand letter, a landlord complaint letter, or an unpaid salary demand.

What a letter of demand must include

A demand that gets actioned contains all of the following. Leave one out and the recipient has an easy excuse to stall.

• Your details and theirs — full names, and the correct legal or company name of the recipient.
• A clear heading — "Letter of Demand" so there's no doubt about what it is.
• The facts — a short, unemotional account of what happened, with dates, amounts and reference numbers.
• The legal or contractual basis — the agreement, invoice, or the Act that supports your claim (for example the Consumer Protection Act or the Rental Housing Act).
• The exact demand — the amount to be paid or the specific thing to be done.
• A firm deadline — a specific date, not "as soon as possible".
• The consequence — what you'll do if the deadline passes (refer to the ombud, or institute legal action).
• How to pay or respond — banking details or a contact, so there's no excuse not to comply.

Tone and deadline

The most effective letters of demand are firm but unemotional. Anger reads as weakness; a calm, precise letter that quotes the relevant rule reads as someone who is prepared to follow through. Avoid threats you can't carry out and avoid insults entirely — both can be used against you later.

On timing, 10 business days is the standard, reasonable period for most demands. It's long enough to be fair and short enough to keep pressure on. Always express it as a dated deadline ("by no later than 25 August 2026"), not a vague window.

How to send it and keep proof

Delivery matters as much as content, because you may need to prove the letter was received. Good practice:

• Send by email and keep the sent item and any read receipt.
• Where the contract specifies a delivery address (a domicilium), use it.
• For higher-value matters, add registered post or a trackable courier.
• Keep a copy of the signed letter and a note of the date sent.

What happens if it's ignored

If the deadline passes with no response, your next step depends on the type of dispute:

• Consumer and financial disputes — escalate free to the relevant ombud (for example the National Financial Ombud for banks and insurers, or the Consumer Goods and Services Ombud for retail).
• Rental disputes — the provincial Rental Housing Tribunal, at no cost.
• Smaller money claims — the Small Claims Court, for amounts up to the prescribed limit, with no attorney needed.
• Larger claims — the Magistrate's Court or High Court, usually with legal representation.

In every one of these, your letter of demand becomes part of your evidence that you acted reasonably and gave fair warning.

A simple structure you can follow

If you're writing it yourself, follow this skeleton:

1. Your name and contact details, and the date.
2. The recipient's name and address.
3. Heading: LETTER OF DEMAND.
4. Paragraph 1 — the facts and the background.
5. Paragraph 2 — the basis of your claim (contract or law).
6. Paragraph 3 — the specific demand and the dated deadline.
7. Paragraph 4 — the consequence of non-compliance.
8. How to pay or respond, then sign off.
