Thai Defamation Law for Phuket Expats: What You Must Know Before You Post

A British expat based in Rawai posted a detailed negative review of his landlord on a Phuket Facebook group. Every word was true. He had receipts, photos, and WhatsApp messages to prove it. He was arrested two weeks later under Thailand's Computer Crimes Act and spent three nights in Phuket's Muang Police Station before posting bail.

Thai defamation law works very differently from what most Western expats expect. In the UK, the US, or Australia, truth is typically an absolute defence. In Thailand, it is not. You can be charged for saying something true if a court decides the disclosure wasn't in the public interest. This isn't hypothetical — it catches expats in Phuket every year.

This guide is not legal advice. It's a frank explanation from someone who has lived in Phuket for six years and watched people make expensive, avoidable mistakes online. If you're facing a specific legal situation, contact a qualified Thai lawyer (see our Phuket legal services guide).

The Legal Framework: Two Laws That Apply

In Thailand, defamation is addressed by two separate pieces of legislation, and both can apply to expats in Phuket:

1. Criminal Code Sections 326–328

Section 326 defines defamation as imputing something to another person "in a manner likely to impair the reputation of such other person or to expose such other person to be hated or scorned." The offence is criminal, meaning the complainant goes to the police — not just a civil court. Penalties: up to 1 year imprisonment and/or a fine up to 20,000 THB.

Section 328 increases the penalty for defamation via "document, drawing, painting, cinematograph film, picture, photograph, phonogram, or any other record." This includes social media posts, meaning a Facebook post carries higher potential penalties than a spoken statement.

2. Computer Crimes Act BE 2550 (2007)

This is the law that catches most expats off guard. Section 14 of the Computer Crimes Act makes it an offence to input "false computer data in a manner that is likely to cause damage to the public." This has been interpreted broadly by Thai courts to include defamatory content posted online — even in private groups. The penalty under this act: up to 5 years imprisonment and/or a fine up to 100,000 THB.

Why Truth Is Not Enough Protection

Thai law does provide a limited "public interest" defence — Section 329 of the Criminal Code allows truth as a defence if the statement was made "for the public benefit." However, the interpretation of "public benefit" is narrow and decided by a judge. Cases where truth was not accepted as a defence include:

• A hotel guest who posted accurate reviews of bad conditions — the court found the damage to the hotel outweighed the public benefit
• An expat who accurately described a contractor's substandard work — charged because the contractor claimed business damage
• A tenant who shared a landlord's threatening messages — charged under the Computer Crimes Act for "false data" because the landlord disputed the context

The lesson: in Thailand, the burden is effectively on you to demonstrate your statement was in the public interest. Don't assume truth protects you.

What Can Get You In Trouble in Phuket

Negative Facebook Group Posts

Phuket's expat Facebook groups — Phuket Expats, Expats Phuket, and various area-specific groups — are viewed as public forums by Thai courts. A post in a group with thousands of members is treated similarly to a published news article for defamation purposes. "Private" or "secret" groups offer limited protection.

Google and TripAdvisor Reviews

Reviews published on Google Maps, TripAdvisor, or Agoda about Phuket businesses are accessible in Thailand and have been used as the basis for criminal complaints. Phuket hotel and restaurant owners have successfully prosecuted reviewers under the Computer Crimes Act.

WhatsApp and Line Groups

Even messages in a shared group chat can be used as evidence of defamation if screenshotted and presented to police. The fact that you thought the message was "private" is generally not a defence if the group had multiple members.

Phuket Expat Forums and Reddit

Posts on Reddit (r/Thailand, r/phuket) and expat forums visible in Thailand carry the same risk. Screenshots travel. A post written in anger from a co-working space in Cherng Talay can end up as a police exhibit.

How to Complain or Warn Others Legally

This doesn't mean you have to stay silent. Here's how to express negative experiences with reduced legal risk:

• Use "I" statements and personal experience — "I experienced the following…" is safer than "This business does X" (which sounds like an objective claim)
• Stick to documented facts — If you have receipts, photos, and contracts, reference them specifically
• Avoid character claims — Don't say someone is "dishonest" or a "fraudster" unless you can prove a criminal conviction. Say "in my experience" instead
• Don't speculate about motives — "I believe they intended to…" is still potentially actionable
• Report to official bodies — A complaint to the Consumer Protection Board, Tourism Authority of Thailand, or relevant regulatory body is legally protected speech

If You're Facing a Defamation Complaint in Phuket

If someone has filed — or threatened to file — a defamation complaint against you in Phuket, here's the immediate priority list:

1. Do not delete the post — Deleting content after a complaint can be interpreted as admission. Consult a lawyer before doing anything.
2. Contact a Thai lawyer immediately — Even before you're formally charged, legal advice can change outcomes significantly. See our Phuket legal services directory for recommended English-speaking lawyers.
3. Document your evidence — Screenshot everything supporting your original statement. Store it in cloud storage outside Thailand.
4. Do not discuss the case publicly — Any further public statements can be used as additional evidence or result in additional charges.
5. Contact your embassy — If you're arrested, your embassy can provide a consular visit and a list of recommended lawyers.

The Bigger Picture: Thai Social and Legal Culture

Understanding why this matters goes beyond just knowing the law. Thai culture places significant weight on saving face (การรักษาหน้า). A public accusation — even a factual one — that causes public embarrassment can provoke a strong reaction that a similar situation in the West would not. The legal tools to respond are readily available, inexpensive to use (filing a police complaint costs almost nothing), and genuinely effective.

This doesn't mean avoiding all honest communication. It means understanding the context you're operating in. What reads as a reasonable consumer review in Melbourne or Manchester reads very differently in the Thai social and legal landscape. Adapt accordingly.
