Received a Defamation Letter — What It Means and Your Options

Opening a letter that accuses you of defamation or libel can feel genuinely alarming — especially if you've never dealt with legal correspondence before. Take a breath. Receiving this kind of letter does not mean you are about to be dragged into court. In most cases it is the very first step in a process, and you have real options available to you.

What does this actually mean?

A defamation letter — sometimes called a letter before action or a cease and desist letter — is a formal written notice from someone (or their solicitor) who believes you have damaged their reputation by publishing or sharing false information about them. In UK law, defamation covers two things:

• Libel — a false statement made in a permanent form, such as a social media post, a review, an article, or a message that was forwarded or shared.
• Slander — a false statement made verbally, which is harder to pursue legally and less commonly the subject of these letters.

The relevant law is the Defamation Act 2013, which sets out that a claimant (the person making the complaint) must show that what you published was false, that it referred to them, and that it caused or is likely to cause serious harm to their reputation. That "serious harm" threshold is important — it is a meaningful legal test, not just a matter of hurt feelings.

The letter will usually set out what statement they object to, why they say it is untrue, and what they want you to do — typically a removal of the content, a public apology, or financial compensation, or some combination of these.

Do you need to act immediately?

Not necessarily — but you should not ignore the letter either. Here is what you need to know about timing:

• The limitation period for defamation claims in England and Wales is one year from the date the statement was first published (under the Limitation Act 1980). This means the person sending the letter has a fixed window to bring a claim, and after that window closes, they generally cannot sue.
• The letter itself is not a court claim. A formal claim would be issued through the courts — most defamation cases are heard in the King's Bench Division of the High Court, though lower-value cases can sometimes proceed in the County Court.
• If the letter gives you a specific deadline to respond — commonly 14 days — try to meet it, or at the very least acknowledge receipt and ask for more time. Silence can be taken as a lack of good faith.
• If you have already been served with a Claim Form from the court (a different document from a letter), you typically have 14 days to acknowledge service and 28 days to file a defence. In that situation, speak to a solicitor as soon as possible.

Your next steps

1. Read the letter carefully. Identify exactly what statement is being complained about, where it was published, and what the sender is asking for.
2. Do not delete anything yet. Removing content before you take advice could affect your position — and in some circumstances it could even be seen as an admission.
3. Gather evidence. Screenshot or save a copy of the original statement, any context around it, and anything that supports why you believed it to be true when you published it.
4. Consider whether the statement was accurate. Truth is an absolute defence to defamation in English law. If what you said was true, and you can show evidence of that, you have a strong position.
5. Think about your other defences. Honest opinion (what used to be called "fair comment") and publication on a matter of public interest are also recognised defences under the Defamation Act 2013.
6. Respond in writing. Even if only to acknowledge receipt and say you are taking advice. Keep your response factual and measured.

When should you speak to a solicitor?

You should seek legal advice promptly if:

• The letter is from a solicitor's firm, which suggests the other side is already serious about pursuing this.
• You have received a court Claim Form rather than just a letter.
• The complaint involves your business or professional reputation, where the financial stakes are higher.
• You are unsure whether what you published could genuinely cause the claimant serious harm.
• You are being asked to pay a significant sum in damages.

A specialist defamation solicitor can assess your exposure honestly, advise on your defences, and in many cases help resolve things quickly — sometimes a well-worded response is enough to settle matters without any court proceedings at all.
