Defamation in Thailand: Thai Criminal Law, Penalties and What to Do If You Are Accused

Defamation in Thailand is a criminal offense that can have serious legal consequences. A person may face criminal prosecution for making or publishing statements that damage another person's reputation.

Defamation disputes can arise from conversations, letters, emails, Facebook posts, online reviews, comments, videos, and other forms of communication.

For foreigners living or doing business in Thailand, it is particularly important to understand Thai defamation law because conduct on social media or other platforms may result in proceedings under Thai law.

This article explains defamation under Thai criminal law, the relevant provisions of the Thai Criminal Code, potential penalties, online defamation, available defenses, and what you should do if you are accused of defamation in Thailand.

1. What Is Defamation Under Thai Law?

The principal provision concerning defamation is Section 326 of the Thai Criminal Code.

In general, a person may commit defamation if they make an allegation concerning another person to a third party in a manner that is likely to damage that person's reputation or expose that person to hatred or contempt.

The important elements generally include:

1. 01There is an allegation concerning another person
2. 02The allegation is communicated to a third party
3. 03The statement is capable of damaging the person's reputation or exposing that person to hatred or contempt
4. 04The accused intentionally makes or communicates the allegation

The exact circumstances must be examined in each case.

2. What Is the Penalty for Defamation?

Under Section 326, ordinary defamation is punishable by:

• Imprisonment of up to 1 year
• A fine of up to 20,000 baht
• Or both

The court determines the appropriate punishment based on the circumstances and evidence presented in the case.

3. Defamation by Publication – Section 328

Thai law provides a more serious offense where defamation is committed through publication.

Section 328 of the Thai Criminal Code concerns defamation committed by means of publication.

This may include circumstances involving:

• Newspapers
• Websites
• Facebook
• Instagram
• TikTok
• YouTube
• Public online posts
• Public comments
• Images containing defamatory statements
• Other forms of widespread communication

The maximum penalty under Section 328 is:

• Imprisonment of up to 2 years
• A fine of up to 200,000 baht
• Or both

Whether a particular online post constitutes publication under Section 328 depends on the circumstances and manner in which the information was communicated.

4. Can a Facebook Post Be Defamation in Thailand?

Yes.

A Facebook post can potentially constitute defamation if the legal elements of defamation are satisfied.

Examples may include publicly accusing another person of:

• Stealing money
• Fraud
• Criminal conduct
• Dishonesty
• Professional misconduct
• Business misconduct
• Unethical behavior

However, not every negative statement is automatically defamatory.

The court may consider the actual wording, context, intended meaning, audience, surrounding circumstances, and evidence.

5. What About Google Reviews?

Online reviews can create legal risks when they contain allegations about identifiable individuals or businesses.

For example, a customer who writes:

"This company stole my money."

may create a legal issue if the statement is understood as alleging criminal conduct rather than simply expressing dissatisfaction.

By contrast, statements that clearly express an opinion about personal experience may require a different legal analysis.

The distinction between fact and opinion, the wording used, and the context are therefore important.

6. Defamation vs. Insult

Defamation and insult are not the same offense under Thai law.

Section 326 generally concerns communicating an allegation about another person to a third party in a manner capable of damaging reputation.

Section 393 concerns insulting another person in a manner specified by law.

For example, a statement that merely uses offensive or insulting language may raise different legal issues from a statement alleging that a person committed a particular dishonest or criminal act.

The exact words and context are important.

7. Does Telling the Truth Mean There Is No Defamation?

Not necessarily.

Thai law contains specific provisions concerning defenses involving statements made in good faith and the proof of truth.

Section 329 provides circumstances in which a person may be protected from liability for statements made in good faith in situations specified by law.

Section 330 addresses the issue of proving the truth of the allegation.

However, a person should not assume that saying "what I posted was true" automatically eliminates criminal liability.

The court may consider:

• Whether the allegation was true
• Whether the accused can prove the relevant facts
• The purpose of the statement
• Whether the statement was made in good faith
• Whether the matter involved a legitimate public interest
• The manner in which the information was communicated

8. Defamation Concerning a Deceased Person

Thai law also provides specific protection concerning allegations made about a deceased person.

Section 327 of the Thai Criminal Code concerns certain defamatory statements concerning a deceased person where the conduct is capable of causing damage to specified persons connected to the deceased.

Therefore, the fact that a person has died does not necessarily mean that statements concerning that person are free from legal consequences.

9. Online Defamation in Thailand

Social media has become one of the most common sources of defamation disputes.

Potentially relevant conduct includes:

• Posting on Facebook
• Commenting on another person's post
• Posting on Instagram
• Publishing a TikTok video
• Uploading a YouTube video
• Posting a Google review
• Publishing allegations on a website
• Sharing defamatory content
• Posting photographs together with defamatory captions

The fact that information is published online can increase the potential audience and may have significant consequences for the person who is the subject of the allegation.

10. What Evidence Is Important in a Defamation Case?

Evidence is extremely important in defamation cases.

Screenshots

Screenshots may show:

• The exact wording
• The account that published the statement
• The date and time
• Comments and reactions
• The context of the publication

URLs and Web Pages

The original URL can help establish where and how the statement was published.

Witnesses

People who saw or heard the statement may become relevant witnesses.

Messages and Emails

Private communications may help establish the context, intention, or background of the dispute.

Audio and Video

Recordings may be relevant depending on how they were obtained and whether they are legally admissible.

Evidence of Identity

In online cases, it may be necessary to establish who actually controlled the account that published the allegedly defamatory content.

11. What Should You Do If You Are Accused of Defamation?

If someone accuses you of defamation in Thailand, you should take the matter seriously.

Do Not Immediately Delete Everything

Preserve the original material and surrounding evidence before making decisions about deletion.

Do Not Continue the Dispute Online

Posting additional accusations or aggressive responses may create additional legal problems.

Obtain Legal Advice

A Thai lawyer can review:

• The exact statement
• Where it was published
• Who received or saw it
• Whether the statement identified the complainant
• Whether the statement was factual or opinion
• Whether a legal defense may apply
• Whether the matter is potentially compoundable

Preserve the Context

Do not provide only an isolated sentence if the surrounding conversation changes the meaning.

Keep:

• The original post
• Previous messages
• Comments
• Replies
• Screenshots
• URLs
• Emails
• Relevant documents

12. What Should You Do If Someone Defames You?

If you believe that another person has defamed you, consider taking the following steps:

1. 01Preserve the original evidence
2. 02Take screenshots showing the complete context
3. 03Save the URL
4. 04Record the date and time
5. 05Identify witnesses
6. 06Avoid unnecessary public arguments
7. 07Consider making a police complaint where appropriate
8. 08Obtain legal advice concerning criminal and civil remedies

Evidence should be preserved as soon as possible because online content can be edited or deleted.

13. Can a Defamation Case Be Settled?

Defamation is generally treated differently from offenses that the state prosecutes regardless of the victim's wishes.

Under Section 333 of the Thai Criminal Code, defamation offenses are generally subject to the rules concerning compoundable offenses.

This means that settlement and withdrawal of the complaint may be possible in appropriate circumstances.

However, the legal effect of a settlement depends on:

• The exact offense
• The stage of the proceedings
• The terms of the settlement
• Whether the complaint has already been filed
• Whether the withdrawal is legally effective

A written settlement should therefore be carefully prepared.

14. Criminal Defamation and Civil Damages

A defamation dispute may involve both criminal liability and civil liability.

The criminal case concerns whether the accused committed a criminal offense.

Separately, the person whose reputation has been damaged may potentially seek compensation for damages under applicable civil law.

Potential claims may involve:

• Damage to reputation
• Financial losses
• Business losses
• Other legally recoverable damages

The appropriate legal strategy depends on the circumstances.

15. Defamation and Foreigners in Thailand

Foreigners can potentially be prosecuted under Thai defamation laws for conduct falling within Thai jurisdiction.

This can include disputes involving:

• Foreign business owners
• Expatriates
• Foreign employees
• International couples
• Foreign customers
• Business partners
• Social media users

A foreigner involved in a Thai defamation case may need assistance with:

• Police procedures
• Thai-language documents
• Translation
• Evidence collection
• Complaint procedures
• Bail
• Criminal court proceedings
• Civil compensation claims

16. What If the Defamation Is in English?

The fact that a statement is written or spoken in English does not automatically prevent Thai authorities from considering it.

The authorities and court may need an appropriate translation to determine the meaning of the statement.

The important issue is whether the statement satisfies the legal requirements for defamation and whether Thai law has jurisdiction over the conduct.

17. Common Examples of Potential Defamation

The following types of statements may create legal issues depending on their wording and context:

• "He stole my money."
• "She committed fraud."
• "This person is a criminal."
• "This lawyer takes clients' money and does not do the work."
• "This company cheats customers."
• "He is running an illegal business."

However, whether a particular statement constitutes defamation cannot be determined simply by looking at one sentence.

The court may examine the complete context and surrounding circumstances.

18. Common Questions About Defamation in Thailand

Can I be sued for a negative Facebook post?

Potentially, yes. A post may constitute defamation if it satisfies the legal elements of the offense.

Can I be sued for a Google review?

Potentially. A review containing allegations about an identifiable person or business may create legal risks depending on its wording and circumstances.

Is criticizing a company illegal?

Not necessarily. Legitimate criticism and defamatory allegations are different legal issues. The exact wording and context are important.

Can I defend myself by proving that the statement is true?

Potentially. Sections 329 and 330 may become relevant, but the availability of a defense depends on the facts and legal requirements.

Can foreigners be charged with defamation in Thailand?

Yes. Foreign nationals can potentially be investigated and prosecuted under Thai law where the relevant legal requirements and jurisdictional conditions are satisfied.

Can a defamation case be settled?

In appropriate cases, yes. Defamation offenses are generally compoundable under Section 333, subject to the applicable legal requirements and procedural stage.

19. Why You Should Consult a Thai Lawyer

Defamation cases can be highly dependent on the exact words used.

A small difference in wording may determine whether a statement is:

• A factual allegation
• An opinion
• An insult
• A criticism
• A statement made in good faith
• Potentially defamatory

A lawyer can review the complete circumstances and advise whether there may be grounds for filing a complaint, defending the allegation, negotiating a settlement, or pursuing civil remedies.

Conclusion

Defamation in Thailand can result in criminal and civil legal consequences.

The key provisions include Sections 326 and 327 of the Thai Criminal Code, while Section 328 addresses defamation by publication. Sections 329 and 330 may be relevant to potential defenses, while Section 333 concerns the compoundable nature of defamation offenses.
