Legal Notice: How to Send One and How to Reply

A legal notice formally puts the other side on notice of your claim. In some cases it is legally mandatory; in many others it resolves the dispute without going to court.

What a Good Notice Contains

  • Full names and addresses of the sender and recipient
  • A clear, chronological statement of facts with dates and documents
  • The legal basis of the claim
  • The specific demand — payment, performance, or stopping a wrongful act
  • A reasonable deadline, and the action that will follow if it is not met

Send it by registered post / speed post with acknowledgement, and also by email. Keep proof of dispatch and delivery — it is often key evidence.

If You Receive a Legal Notice

  1. Do not ignore it. Note the date of receipt and any deadline.
  2. Do not reply in anger or make admissions by phone or message.
  3. Consult a lawyer and collect your documents.
  4. Send a reasoned reply denying incorrect claims and stating your position. With an IBC demand notice, failing to point out an existing dispute within 10 days can have serious consequences.

Frequently Asked Questions

Is it compulsory to reply to a legal notice?

There is usually no legal obligation to reply, except where a statute requires a response, such as an IBC demand notice. However, it is advisable to send a proper reply, because silence may be used against you and the reply records your defence at an early stage.

How many days do I have to reply to a legal notice?

Most notices give 7 to 30 days. Statutory notices have fixed periods, such as 15 days to pay in a cheque bounce notice and 10 days to respond to an IBC demand notice.

Can a legal notice be sent by WhatsApp or email?

Courts have accepted service by email and WhatsApp in several situations. It is still safest to send the notice by registered or speed post as well, and to keep proof of delivery.
