A false post on X, a damaging message in a WhatsApp group or a careless remark at a public meeting can harm a reputation built over many years. Kenyan law protects reputation, but it also protects free speech, and the line between the two is not always obvious. This guide explains what defamation is, the defences, the deadline for suing and what you can do about it.
What is defamation?
A statement is defamatory if it tends to lower a person in the estimation of right-thinking members of society, or exposes them to hatred, ridicule or contempt, or causes others to shun or avoid them. To succeed in a claim, you generally need to show that:
- the statement was defamatory;
- it referred to you, whether by name or in a way that people would understand to mean you; and
- it was published, meaning that it was communicated to at least one person other than you.
Truth is a defence, which the person who made the statement must prove.
Individuals can sue for defamation, and so can companies whose trading reputation has been harmed.
Libel and slander
- Libel is defamation in a permanent form: print, broadcast, online posts, comments, videos and messages. Libel is actionable without proof that you suffered financial loss.
- Slander is spoken defamation. It generally requires proof of actual financial loss, except in certain categories, such as words that disparage you in your office, profession, trade or business, which are covered by the Defamation Act (Cap. 36).
Defamation online
Social media posts, comments, blogs and messages in WhatsApp or Telegram groups are all capable of being libel. Sharing or reposting someone else’s defamatory statement can also be a publication by you. Where the author hides behind an anonymous account, it may be possible to obtain court orders requiring a platform or service provider to disclose who is behind it.
Defamation is now a civil matter
In Jacqueline Okuta & another v Attorney General & 2 others [2017] eKLR, the High Court declared the offence of criminal defamation in the Penal Code unconstitutional. Defamation is therefore pursued through a civil claim, not a criminal complaint.
The Computer Misuse and Cybercrimes Act, 2018 created offences of false publication (section 22) and publishing false information (section 23). On 6 March 2026, the Court of Appeal declared both sections unconstitutional in a challenge brought by the Bloggers Association of Kenya. The Director of Public Prosecutions has asked the Supreme Court to overturn that decision, so the final position may still change. Other offences, such as cyber harassment, are unaffected.
The main defences
- Justification (truth). Under section 14 of the Defamation Act, the defence does not fail merely because the truth of every allegation is not proved, if the unproved words do not materially injure the claimant’s reputation given the truth of the rest.
- Fair comment. An honest opinion on a matter of public interest, based on true facts, is protected (section 15).
- Absolute privilege. Statements made in court proceedings and in Parliament cannot found a defamation claim.
- Qualified privilege. Fair and accurate reports, and statements made in the performance of a duty to someone with a legitimate interest in receiving them, are protected unless the maker acted with malice.
- Unintentional defamation. A person who published innocently may limit their liability by promptly making an offer of amends, such as a correction and an apology.
Act quickly: the 12-month deadline
A claim for libel or slander must be filed within 12 months of publication, under the Limitation of Actions Act. That is much shorter than the limit for most other claims.
What you can do
- Preserve the evidence. Take screenshots showing the content, the account, the date and the web address, and ask a witness to confirm what they saw. Posts can be deleted at any time.
- Do not retaliate in kind. A defamatory reply can expose you to a counterclaim.
- Send a demand letter. A letter from an advocate can demand that the statement be taken down, a retraction and apology published, an undertaking not to repeat it and compensation paid. Many cases end at this stage.
- Report the content to the platform under its own rules.
- Complain to the Media Council of Kenya if the statement was published by a media house. Its Complaints Commission handles complaints against journalists and media organisations.
- File a claim in court if the matter is not resolved.
Remedies in court
The court may award:
- general damages for the harm to your reputation;
- aggravated damages, where the defendant’s conduct made the harm worse, for example by refusing to apologise;
- an injunction stopping further publication; and
- an order for publication of an apology or correction.
Courts grant injunctions before trial in defamation cases only in clear cases, because of the importance of free expression.
If you are accused of defamation
Take the demand letter seriously and seek advice before replying. If what you said is true, gather the evidence to prove it. If you got something wrong, a prompt correction and apology can greatly reduce your exposure.
Frequently asked questions
Can I sue over a message in a WhatsApp group?
Yes. A message sent to a group is published to every member who received it.
Can I report defamation to the police?
Defamation itself is now a civil matter. You can report related conduct that remains a crime, such as threats or cyber harassment.
How much compensation can I get?
It depends on how serious the allegation was, how widely it spread, who you are and how the defendant behaved afterwards. Courts look at awards made in comparable cases.
