The Letter of Complaint and Other Official Letters

Why this model scores. Account number and bill date in the subject line; the disputed figure and the comparison figures; a verifiable fact, the locked premises; independent evidence, the photographed reading; a specific three-part remedy; a deadline; availability for inspection; and an enclosure list.

The other official letters, in outline

MU's label names only letter writing generally, so any of these may be set. Each is a variation on the same seven-part layout.

Letter of enquiry. Asks for information: availability, price, terms, dates. State exactly what you want to know, as a numbered list if there is more than one item, and say by when.

Letter of order. Places an order. Quantities, specifications, price agreed, delivery address, delivery date, and mode of payment. Precision here prevents disputes later.

Letter of adjustment. The reply to a complaint. It acknowledges, states what has been found, says what is being done, and, where the complaint is justified, apologises without excuses. Where it is not justified, it explains why, courteously.

Letter of resignation. Short. State that you resign, state the post, state the effective date having regard to the notice period, thank the employer in one sentence, and offer to assist in the handover. Nothing else, and no grievances.

Letter of leave. Shorter still. The dates, the reason in one line, arrangements for your work in your absence, and contact details.

Letter of reference or recommendation. States how long and in what capacity you have known the person, two or three specific things about their work, and a clear recommendation. Never write one you cannot mean.

Letter to the editor. A public letter about a matter of public concern, usually under two hundred words, taking one point and making it.

And the one that belongs to law: the legal notice. A formal written demand sent before proceedings, setting out the facts, the legal basis of the claim, the relief demanded and a period within which it must be met, failing which action will be taken. Its form and its requirements belong to the procedure papers of later years, and a first-year student should know only that it exists and that it is the professional ancestor of the complaint letter.

What turns a complaint into a legal claim

One paragraph, because a law student will ask.

A complaint letter is the first step. If it is not answered, the writer may have a remedy: in the case of goods and services bought for consideration, the consumer forums provide one, and a written complaint with dated evidence is exactly what such a forum will want to see. This is why the habits taught in this chapter, giving account numbers, keeping copies, photographing evidence, and asking for a reply within a stated period, are not merely tidy: they build the record that a later claim rests on. The law of it belongs to the consumer protection course, and the drafting belongs here.

What loses marks

No account or bill number. The complaint cannot be identified.

Anger. "This is the third time your useless department has cheated me" reads as a person to be managed rather than a claim to be answered.

No specific remedy. "Please do the needful" leaves the reader to decide what you want, and they will decide in their own favour.

No date for a reply. A complaint with no deadline joins the bottom of the pile.

Threatening litigation in the first letter. State the facts and the remedy. A threat in a first letter reduces the chance of the thing being fixed, which is what you actually want.

Forgetting the enclosures. Copies, never originals, and list them.

A worked answer

Question. MU's own, February 2026: "Write a letter of complaint to the electrical department about an overcharged bill you received this month."

The answer is the model above. In the hall, build it in this order and it will take ten minutes.

Invent five specifics first. An account number, the bill date, the amount demanded, the normal amount, and one verifiable circumstance such as premises being locked. Examiners reward invented specifics because they show you know what a complaint needs.

Then the subject line, which contains the account number and the bill date.

Then four paragraphs: the bill complained of; the facts and the comparison figures with the evidence enclosed; the effect and why you will not simply pay; and the remedy with a deadline and your availability.

Then the close, signature and enclosure list.

Do not exceed one page. Six marks.

Quick revision

Five parts: identify the transaction; state what happened with dates; state the effect; state the remedy wanted; give a deadline.

Tone: firm and courteous. Anger is dismissed; dates and figures are not.

Always: account or bill number, copies not originals, an enclosure list, a reply-by date.

Other official letters: enquiry, order, adjustment, resignation, leave, reference, letter to the editor, and the legal notice.

Resignation: the fact, the post, the date, one line of thanks, an offer to hand over. No grievances.

The complaint letter is the ancestor of the legal notice, and the record it builds is what a later claim rests on.

Test yourself

1. What must a complaint identify before anything else? The transaction: the account, bill, invoice or order number, the date and the amount. Without these the complaint cannot be traced and the first reply will simply ask for them.

2. Why should a complaint be courteous? Because the person reading it did not cause the problem and is the person able to fix it, and because a calm letter with dates and figures is far harder to dismiss than an angry one.

3. What are the five parts of a complaint? Identification of the transaction; a statement of what happened, with dates; the effect on you; the specific remedy sought; and a time for reply with a statement of what you will do next.

4. What does a letter of resignation contain, and what must it not? It states that you resign, names the post, gives the effective date having regard to the notice period, thanks the employer in one sentence, and offers help with the handover. It must not contain grievances, explanations or criticism.

5. How does a complaint letter relate to a legal claim? It is the first step and it builds the record. Account numbers, copies of documents, photographed evidence and a stated period for reply are exactly what a consumer forum or a court will later want to see, so the drafting habits taught here are what a subsequent claim rests on.
