A defamatory post on social media can reach thousands of people overnight, while the victim usually reacts by arguing in the comments — a place that resolves nothing except pushing the post further. This article presents the correct legal path when defamed on social media in Vietnam: fix the evidence before the post is deleted, denounce to the right authority, and claim honour compensation with a file rather than with emotion.
Legal basis for defamation on social media in Vietnam
An individual’s right to honour protection sits in Article 34 of the 2015 Civil Code (91/2015/QH13): an individual’s honour, dignity and reputation are inviolable and protected by law, and information adversely affecting honour must be removed or corrected at the request of the infringed person. This provision is the civil foundation for every takedown and public-apology demand in social media defamation cases.
At the criminal layer, the 2015 Penal Code (amended and supplemented in 2017) handles fabricating or spreading falsehoods to seriously infringe another person’s honour and dignity in Article 156 on the offence of slander, and seriously insulting dignity and honour in Article 155 on the offence of humiliating another person. The boundary between a civil case and a criminal case lies in the fabrication and the seriousness of the information, so the same post can travel one of the two routes or both in parallel.
At the internet-governance layer, the 2018 Cybersecurity Law (24/2018/QH14) prohibits false information causing confusion and infringing lawful rights and interests of organisations and individuals in cyberspace, and Decree 147/2024/ND-CP on management, provision and use of internet services sets the mechanism for state authorities to require platforms to remove violating content. This layer gives the victim a fast takedown lever independent of the speed of courts and investigators.
Applying the rules to each question about defamation on social media in Vietnam
Being defamed on Facebook, what can we do? Being defamed on Facebook, the first move is not commenting in self-defence but fixing the entire post, comments and shares as evidence with screenshots including links and times, and making a vi bang if the case value warrants it, before the poster can delete or edit. The second move is using the platform’s reporting mechanism with a takedown request through official channels, because every extra day the post exists multiplies the honour damage.
Where do we denounce it? A denunciation of the defamation is filed with the police where the victim resides or where the poster resides where the conduct shows signs of the slander or humiliation offences, together with the fixed evidence set and a statement identifying exactly which words are fabricated and what the truth is. In parallel, the victim may send a document to the Department of Information and Communications or the cyberspace authority requesting administrative handling and content removal under Decree 147/2024/ND-CP.
Can we claim compensation for honour? Compensation for honour in a social media defamation case is claimed under Article 592 of the 2015 Civil Code on damage from infringed honour, dignity and reputation, comprising reasonable costs to remedy the damage, lost income and a sum for mental suffering agreed by the parties or decided by the court within the lawful frame. The victim may also demand that the violator apologise and publicly correct at the place where the false information spread, a right many people forget although it heals exactly the most wounded part of the case.
Safe steps for defamation on social media in Vietnam

- Report the violation to the social media platform and send a content-removal request through its official channel.

- Prepare the honour compensation claim and the demand for public apology and correction under Article 592 of the 2015 Civil Code.
Common risks in defamation on social media in Vietnam
The biggest risk when defamed on social media is responding with an emotional post containing unverified claims about the other party, turning the victim into a new violator and polluting their own denunciation file. Another risk is slow evidence fixing: a defamatory post can be deleted within hours once the poster senses movement, and by then the victim is left with only their account while the damage has already spread everywhere.
Being defamed on social media in Vietnam has a full three layers of tools: civil law to remove the post, obtain an apology and claim honour compensation; criminal law for serious fabrication; and cyberspace governance to cut the spread at its source. A victim who uses the correct order — fix evidence, remove the post, denounce, claim compensation — turns a defamatory post into a legal file with a clear ending.
Frequently asked questions about defamation on social media in Vietnam
Being defamed on Facebook, what can we do?
Before denouncing social media defamation, the victim should prepare a two-column comparison: the fabricated statements in the post and the truth with evidence for each statement, because a receiving authority assesses such a structured file far faster than a loose pile of screenshots. Being defamed on Facebook, the first move is not commenting in self-defence but fixing the entire post, comments and shares as evidence with screenshots including links and times, and making a vi bang if the case value warrants it, before the poster can delete or edit. The second move is using the platform’s reporting mechanism with a takedown request through official channels, because every extra day the post exists multiplies the honour damage.
Where do we denounce it?
A takedown request for a defamatory post should be sent simultaneously through the platform’s reporting channel and in writing to the management authority, because the two channels run on two different clocks and whichever arrives first shortens the time the post keeps causing harm. A denunciation of the defamation is filed with the police where the victim resides or where the poster resides where the conduct shows signs of the slander or humiliation offences, together with the fixed evidence set and a statement identifying exactly which words are fabricated and what the truth is. In parallel, the victim may send a document to the Department of Information and Communications or the cyberspace authority requesting administrative handling and content removal under Decree 147/2024/ND-CP.
Can we claim compensation for honour?
Honour compensation for social media defamation becomes more persuasive when the victim proves concrete consequences such as a lost contract, a lost job or psychological treatment, instead of only asserting mental suffering in general terms. Compensation for honour in a social media defamation case is claimed under Article 592 of the 2015 Civil Code on damage from infringed honour, dignity and reputation, comprising reasonable costs to remedy the damage, lost income and a sum for mental suffering agreed by the parties or decided by the court within the lawful frame. The victim may also demand that the violator apologise and publicly correct at the place where the false information spread, a right many people forget although it heals exactly the most wounded part of the case.
