Defamation Advice
& Representation
Thai defamation law carries criminal as well as civil consequences. Whether you have received a legal letter or a police summons, believe you have been defamed, or need early advice before the situation worsens, acting quickly determines what remains possible.
Who We Help
Two sides of the same legal area
A defamation matter can arise in two directions. Someone has received a complaint and needs to defend against it, or someone has been defamed and wants to pursue a claim. Both require early advice — and in both cases, what happens in the first days after the situation arises usually determines the options that remain available.
These are the situations that typically bring clients to us.
Facing a Complaint
A legal letter, police summons or formal complaint has been received about something published or communicated — online or otherwise. The priority is early advice before the position worsens.
Reputation Damaged by False Publications
False or misleading information has been published and is causing identifiable harm — to reputation, to a business or to professional standing. Legal advice assesses the basis for a claim and what remedies are available.
Seeking Advice Before It Escalates
A dispute is developing, a threatening communication has been received, or there is uncertainty about how to respond. Early advice determines what remains possible before the matter becomes more serious.

In Practice
What usually happens in reality
Most defamation complaints that are addressed early — with proper advice and without further escalation — are resolved without court proceedings. The ones that proceed to prosecution are usually where someone ignored early contact, continued posting about the subject, or attempted to handle the matter without legal advice. Three things matter immediately when a complaint arises.
Do Not Ignore a Summons or Legal Letter
In Thailand, ignoring a formal criminal complaint does not make it go away. It can result in an arrest warrant being issued. Early action keeps options open that delay removes.
Do Not Delete Existing Content
Deleted content can still be recovered, and deletion after a complaint has been received can itself complicate the position. Preserve everything until you have taken advice.
Do Not Post Further About the Matter
Additional posts about the subject of a complaint can each generate fresh legal exposure. Once a complaint is pending, further communication on the matter is handled through the legal team.
How We Help
From first contact to representation
Five steps, from the initial assessment through to representation in proceedings or pursuit of a client's own claim.
01
Initial Consultation and Assessment
Establish what has happened, what has been alleged or published, what stage the matter has reached and what outcome you are seeking.
02
Review the Publication and the Complaint
Work through what was published, the circumstances, the complaint or claim, and give a realistic view of the position under the Criminal Code and the Computer Crimes Act where relevant.
03
Advise on Immediate Steps
Set out what not to do — what not to delete, what not to post, whether to contact the complainant — and what evidence to preserve before anything else changes.
04
Prepare the Defence or the Claim
Build the defence for criminal or civil proceedings, or prepare the basis for a defamation complaint on behalf of a client whose reputation has been damaged.
05
Represent You Through the Proceedings
Act in dealings with the police and prosecutors and in court, and advise on the immigration implications of criminal proceedings as they arise.
The outcome of a defamation matter depends on the facts, the evidence and the specific circumstances. No outcome is promised, and a realistic assessment is given from the first consultation.
What to Bring
Documents that allow the position to be assessed
Having the following ready at the first meeting means the matter can be assessed without a second round of requests.
- The legal letter, police summons or formal demand (if received)
- Screenshots of the content complained about, with dates and timestamps
- Screenshots or archives of your own posts and originals
- Any messages or correspondence relating to the complaint
- Previous warnings, communications or related prior exchanges
- Your passport and current visa or immigration documents
Do not delete any content that might be relevant, and do not contact the complainant or post further about the subject before taking advice.
