How to Respond to a Demand Letter: Practical Guide with Examples

What is a demand letter?

A demand letter is a formal written notice — usually from a lawyer — asking you to do something: pay money, stop an activity, return property, or comply with an agreement. It's the most common type of legal notice people receive.

A demand letter is not a court order. You won't go to jail for ignoring it. But ignoring it can lead to a lawsuit, and the letter itself becomes evidence that you were warned.

Do you have to respond?

Legally, in most cases, no. But practically, you should almost always respond. Here's why:

Silence can be used against you — courts may interpret non-response as acceptance of the claims
It starts a clock — many demand letters set a deadline, after which the sender can escalate
It's your chance to negotiate — responding can resolve the dispute without court
It protects your position — a well-structured response puts your version on record

What to check first

Before writing a single word, answer these questions:

Is the claim valid?

Read the demand carefully. Does the other side have a point? Partial validity is common — they may be right about some things and wrong about others.

What evidence do you have?

Gather contracts, emails, receipts, and messages. Your response should be grounded in documents, not feelings.

Is there a deadline?

If the letter says "respond within 14 days" and it's already day 10, prioritize.

Who sent it?

A letter from a large law firm carries different weight than one from a sole practitioner. But the legal effect is the same — it's the claims that matter.

How to structure your response

Here's a template structure that works for most situations:

Opening

> "Dear [Lawyer/Firm name],

> I refer to your letter dated [date] addressed to me on behalf of [client name] regarding [brief description]."

Point-by-point response

Address each demand or allegation separately. For each:

If you agree: acknowledge it simply
If you disagree: state your position and cite evidence
If you partly agree: specify what you accept and what you dispute

Evidence references

> "I enclose copies of [documents] which demonstrate that [your point]."

Your position

State clearly what you are willing to do and what you are not.

Proposed resolution

If you want to settle:

> "Without prejudice, I am prepared to [proposal] as a full and final resolution."

Closing

> "I trust the above addresses the matters raised in your letter. I reserve all my rights."

Common mistakes

Being too emotional — keep it factual, not angry
Making new admissions — don't volunteer information they didn't ask for
Threatening back — "I'll sue you too" rarely helps
Using "without prejudice" incorrectly — this phrase has specific legal meaning; it protects settlement discussions from being used in court
Not keeping a copy — always keep a copy of everything you send

When to ignore a demand letter

In rare cases, the right move is no response:

The claims are clearly frivolous with no basis
The sender has no standing (they're not the affected party)
You've already resolved the matter and have proof
A lawyer advises you not to respond

Even then, keep the letter on file.

What happens if you don't respond?

The sender's next steps are usually:

Send a follow-up letter — more urgent tone, shorter deadline
File a Magistrate's Complaint — in Singapore, this initiates mediation
File a civil claim — Statement of Claim in court
Report to authorities — if the matter involves regulation (e.g., MOM, ACRA)
