\"Defamation
Understanding defamation law in Thailand, legal risks of social media posts, and how to protect your rights when communicating online.<\/figcaption><\/figure>\n\n\n\n

Short answer:<\/strong> In Thailand, defamation is a criminal offence<\/a>, not only a civil wrong. A Facebook, TikTok, X or Instagram post that alleges facts damaging someone\u2019s reputation can be prosecuted as defamation by publication under Section 328 of the Thai Criminal Code, punishable by up to two years\u2019 imprisonment and a fine of up to THB 200,000. Truth alone is not always a complete defence, but good-faith fair comment is protected under Section 329. The key question is whether you are asserting a damaging fact or expressing an honest opinion.<\/p>\n\n\n\n

This guide explains the Thai legal framework, recent Thai Supreme Court rulings on Facebook posts, and practical steps for individuals and businesses.<\/p>\n\n\n\n

How Thai Law Defines Defamation (Section 326)<\/h2>\n\n\n\n

Under Section 326 of the Thai Criminal Code, a person commits defamation by imputing something to another person before a third party in a manner likely to impair that person\u2019s reputation or expose them to contempt or hatred. The basic offence carries up to one year\u2019s imprisonment, a fine of up to THB 20,000, or both. Three elements matter:<\/p>\n\n\n\n

    \n
  1. An imputation<\/strong> \u2014 a statement presented as fact, such as an allegation of fraud, theft or misconduct.<\/li>\n\n\n\n
  2. A third party<\/strong> \u2014 someone other than the person concerned learns of it. The Thai Supreme Court has held that the offence is complete once a third party knows the statement, even if the person defamed is unaware (Supreme Court Judgment No. 6593\/2559 (2016), a case involving statements to a journalist).<\/li>\n\n\n\n
  3. Likely harm to reputation<\/strong> \u2014 assessed from the viewpoint of an ordinary reasonable reader, not the subjective feelings of the person named.<\/li>\n<\/ol>\n\n\n\n

    Unlike some common-law systems, Thailand treats most defamation as a criminal matter that the injured person can initiate, alongside a civil damages claim.<\/p>\n\n\n\n

    Insults Versus Defamation<\/h2>\n\n\n\n

    An abusive word is not automatically defamation. In Supreme Court Judgment No. 3073\/2565 (2022), the Court found that a crude insult which no ordinary person would believe as a factual allegation was not an imputation under Section 326. However, insulting someone publicly may still fall under the separate offence of insult in Section 393.<\/p>\n\n\n\n

    Is a Social Media Post \u201cPublication\u201d Under Section 328?<\/h2>\n\n\n\n

    Section 328 imposes heavier penalties where defamation is committed through documents, images, text displayed by any means, broadcasting or other forms of public announcement. The Supreme Court has described this offence as requiring dissemination to the public at large (Supreme Court Judgment No. 418\/2567 (2024)). Public posts, pages, public groups, short videos and livestreams typically fall within this category. Posts restricted to friends or private chat groups depend on the facts, and may still amount to basic defamation under Section 326 because group members are third parties <\/p>\n\n\n\n

    Five High-Risk Posting Habits<\/h2>\n\n\n\n

    1. Shaming a debtor online<\/h3>\n\n\n\n

    In Supreme Court Judgment No. 7256\/2567 (2024), posting someone\u2019s photo with text suggesting they were a cheat who would not repay a debt was held to be defamation, not good-faith comment under Section 329(1) or (3). The Court indicated that a creditor should pursue the debt through legal action instead. Businesses should use formal demand letters and court proceedings, not public shaming.<\/p>\n\n\n\n

    2. Framing an accusation as a question<\/h3>\n\n\n\n

    Adding \u201cIs it true?\u201d does not neutralise an accusation. In Supreme Court Judgment No. 418\/2567 (2024), repeated question-style posts were found to be a bad-faith attempt to avoid liability, and the poster had not verified the facts or used available complaint channels.<\/p>\n\n\n\n

    3. Posting repeatedly<\/h3>\n\n\n\n

    In Supreme Court Judgment No. 2624\/2567 (2024), nine Facebook posts on different dates, each asserting different facts, were treated as separate offences rather than a single act. Each post can therefore attract its own penalty.<\/p>\n\n\n\n

    4. Sharing someone else\u2019s post<\/h3>\n\n\n\n

    Sharing delivers the content to a new audience. A person who shares, particularly with endorsing comments, may be treated as publishing the statement themselves, depending on intent and context [analysis based on Sections 326\/328 \u2014 no directly matching ruling located; lawyer review].<\/p>\n\n\n\n

    5. Edited or fabricated images<\/h3>\n\n\n\n

    Section 16 of the Computer Crime Act B.E. 2550 (2007), as amended, separately penalises uploading to a publicly accessible system an image of another person that has been created, edited or altered so as to damage their reputation or cause humiliation: up to three years\u2019 imprisonment and a fine of up to THB 200,000, with an exception for good-faith fair comment. Whether AI-generated images fall within \u201ccreated\u201d is a question of interpretation.<\/p>\n\n\n\n

    When Is Criticism Lawful? Sections 329 and 330<\/h2>\n\n\n\n

    Section 329 exempts statements made in good faith for legitimate self-protection, by an official performing duties, as fair comment on any person or thing open to public criticism, or as fair reporting of open court or public meeting proceedings. In Supreme Court Judgment No. 406\/2567 (2024), a Facebook user who criticised the appointment of a senior civil servant was protected as fair comment under Section 329(3); the Court stressed that the prosecution bears the burden of proving bad faith. That case concerned a public official, so its reasoning should not be stretched to purely private disputes.<\/p>\n\n\n\n

    Section 330 allows a defendant to escape punishment by proving the statement is true, but proof is prohibited<\/strong> where the matter is personal and proving it would not benefit the public. \u201cIt\u2019s true\u201d is therefore not an automatic defence in Thailand.<\/p>\n\n\n\n

    Does the Computer Crime Act Apply to Defamation?<\/h2>\n\n\n\n

    Since the Computer Crime Act (No. 2) B.E. 2560 (2017), Section 14(1) on false computer data expressly excludes conduct that constitutes defamation under the Criminal Code. In Supreme Court Judgment No. 2778\/2561 (2018), the Court held that conduct amounting to defamation under Section 328 was not an offence under Section 14(1) or 14(5). Online defamation of an individual is therefore primarily a Criminal Code matter, while Section 16 (edited images) and other limbs of Section 14 may still apply in specific situations.<\/p>\n\n\n\n

    Civil Liability for Damages<\/h2>\n\n\n\n

    Section 423 of the Thai Civil and Commercial Code makes a person liable for damages for asserting or circulating untrue statements that harm another\u2019s reputation, credit or livelihood, even without knowing the statement was false if they ought to have known. For businesses, this is a route to recover losses caused by false online statements.<\/a><\/p>\n\n\n\n

    Deadlines: The Three-Month Complaint Rule<\/h2>\n\n\n\n

    Defamation is a compoundable offence, meaning it can be settled and withdrawn by the injured person. The injured person must file a complaint within three months of learning of the offence and the identity of the offender<\/strong>, otherwise the right lapses. If the injured person dies before filing, a parent, spouse or child may file instead.<\/p>\n\n\n\n
