Someone defamed me on WhatsApp or Facebook — what should I do first?

Finding a false and damaging message about yourself in a WhatsApp group or a Facebook post is upsetting, especially when people you know have read it. What you do in the first few days matters. This is a short action list; our defamation practice page and the linked guides go deeper.

Step 1: Capture the evidence properly

• Screenshot the whole post or message, including the account name or phone number, the date and time, and the group name.
• For Facebook, X, TikTok or similar, copy the URL of the post and the profile.
• Capture comments, shares and reactions, which show how far it spread.
• Ask a trusted person who saw it to save their own copy and note when they saw it.
• Save files in a dated folder; do not edit or crop the originals.

Posts can be deleted quickly, so do this first.

Step 2: Do not reply in anger

A public reply, an insult in return or a counter-post can escalate the dispute, spread the statement further and may expose you to a claim yourself. If you must respond, a short, calm message such as "This is untrue; I am taking advice" is usually enough, but get advice first if you can.

Step 3: Identify the publisher

You need to know who to act against. Note everyone who wrote, shared or repeated the statement. Under section 114A of the Evidence Act 1950, a person whose name, photograph or pseudonym appears on a publication, or who administers or hosts the account or network, is presumed to be its publisher unless they prove otherwise. If the author is anonymous, a court can in suitable cases order a third party to disclose their identity (see Norwich Pharmacal orders).

Step 4: Report and request removal

Use the platform's reporting tools for harassment or false information. Platforms act under their own policies, so removal is not guaranteed, but it can limit further spread. Keep a record of each report. See removing defamatory posts.

Step 5: Consider a letter of demand

A lawyer's letter of demand usually asks the publisher to remove the statement, publish an apology or retraction, undertake not to repeat it and pay compensation or costs. Many disputes resolve at this stage. If not, the next step may be a court claim, and in urgent cases an application for an injunction.

Step 6: Think about the defences you may face

Before acting, consider whether the publisher might rely on justification (truth), fair comment or privilege. A half-truth can still be defamatory, but you should be ready for these arguments. See defamation defences.

Common mistakes: confronting the person publicly, relying on a single cropped screenshot, waiting months before acting, and threatening criminal action as a bargaining tool.

Frequently asked questions

Is a private WhatsApp group "publication"?

Publication means communicating the statement to at least one person other than you. Messages in a group can be publication to its members.

Can I sue someone who only shared or forwarded the post?

Repeating or sharing a defamatory statement can itself be publication. Whether a claim is worthwhile depends on the facts.

Should I make a police report?

Some online conduct may also involve offences, but defamation is usually pursued as a civil claim. Get advice on which route suits your goal.

What if the person deletes the post?

Deletion may help limit harm, but it does not erase publication that already happened. That is why your evidence matters.

Can I get the post taken down quickly?

In urgent cases, a court can grant an interim injunction. See interim injunctions.
