A practical guide to civil liability under section 423 for false statements that harm reputation in Thailand, including how it differs from criminal defamation, what evidence matters, and when platform reporting or civil action may be appropriate.
Why section 423 matters in Thai reputation disputes
When a false statement damages a person’s or business’s reputation in Thailand, the legal response is not limited to criminal defamation. The Civil and Commercial Code section 423 is often relevant because it provides a civil basis for claiming damages where a false statement is made or circulated and causes reputational harm. For businesses dealing with harmful Google reviews, social media posts, or online comments, section 423 can be an important part of the civil side of a broader reputation strategy.
This article is general information, not legal advice. Civil claims, criminal complaints, and platform reports each follow different rules and may lead to different outcomes. In practice, the best path depends on the evidence, the wording of the statement, the audience reached, and the business impact.

What section 423 covers in simple terms
Section 423 is commonly discussed as a civil liability provision for false statements that cause injury to reputation. The core idea is straightforward: if someone publishes a false statement about another person or business in a way that harms reputation, the injured party may seek civil damages if the legal elements are met.
For businesses, this can matter in several common scenarios:
- a review alleges fraudulent conduct that did not happen;
- a former customer publishes a misleading accusation about safety, hygiene, service, or billing;
- a competitor or ex-employee spreads damaging misinformation online;
- a post is shared widely and begins affecting bookings, patient inquiries, or client trust.
Section 423 is especially useful when the main objective is compensation or civil accountability rather than punishment. That said, the same facts may also raise criminal defamation issues under the Thai Criminal Code, particularly sections 326 and 328, depending on how the statement was made and distributed.
How section 423 differs from criminal defamation in Thailand
Thai defamation law has both civil and criminal dimensions, and it is important not to confuse them.
Civil liability under section 423
A civil claim is usually about recovering damages for harm. The claimant typically needs to show that a false statement caused measurable injury, such as loss of revenue, harm to business relationships, extra corrective costs, or reputational damage.
Criminal defamation under sections 326 and 328
Under Thai Criminal Code section 326, defamation generally concerns making an allegation about another person before a third party in a way that damages reputation. Section 328 can increase exposure where the alleged defamation occurs through publication or broader dissemination, including online channels. Criminal cases can involve investigation, complaint procedures, and potential penalties, but they are separate from civil damages claims.
In practical terms, a business may consider both tracks: a civil claim based on section 423 and, where appropriate, a criminal complaint based on the Criminal Code. The right approach depends on the facts, available evidence, and business priorities.
When online reviews may trigger section 423 issues
Online reviews often feel informal, but they can still have legal consequences if they contain false factual allegations. Not every negative review is unlawful. A harsh opinion, subjective criticism, or customer dissatisfaction is not the same thing as a provably false statement.
Section 423 becomes more relevant when a review or post contains assertions that can be checked for truth or falsity, such as:
- false claims that a business engaged in illegal conduct;
- fabricated descriptions of incidents or staff behavior;
- made-up allegations about hygiene, fraud, or safety;
- misleading statements presented as facts rather than opinions.
For hospitality operators, clinics, agencies, and consumer-facing brands in Thailand, the legal and commercial impact can be immediate. A single post may affect search visibility, conversion rates, and long-term trust, especially in Bangkok’s competitive market.
The evidence that usually matters most
In a section 423 matter, evidence is often the difference between a strong case and an uncertain one. Before sending notices or filing claims, it is usually wise to preserve the full record.
- screenshots and links showing the original content;
- date and time stamps;
- profile details and account history where visible;
- copies of related messages or emails;
- proof of business impact, such as cancellations, lost inquiries, or customer complaints;
- internal records showing the statement is false;
- any prior attempts to request correction or removal.
For businesses, it is also helpful to document the operational effect. Courts and counsel may look not only at the statement itself, but also at how it affected revenue, bookings, referrals, or reputation.

How section 423 interacts with platform policies
A common mistake is to treat platform removal, legal liability, and court remedies as if they were the same thing. They are not.
Platform reports rely on the platform’s own policies. For example, Google Business Profile, Tripadvisor, and Booking.com each have review rules that may permit removal of certain content such as spam, conflicts of interest, off-topic material, harassment, or clearly fabricated content. Facebook, TikTok, YouTube, and marketplaces also have community standards or content rules that may support reporting.
That means there are usually two separate questions:
- Does the content violate the platform policy and qualify for removal or limitation?
- Does the content also create civil or criminal liability under Thai law?
Success on one question does not guarantee success on the other. A review may remain online even if legal remedies are available, and a platform may remove content even if no court action is filed.

Does the Computer Crime Act apply?
Sometimes. The Computer Crime Act may become relevant where false data is entered into a computer system, where online conduct is used to spread harmful misinformation, or where platform-related conduct raises separate digital-offense issues. However, it should not be assumed to apply automatically to every bad review or online dispute.
In reputation cases, lawyers usually assess whether the facts fit the Civil and Commercial Code, criminal defamation provisions, and any possible Computer Crime Act angle. The correct framing matters, because overreaching can weaken credibility while under-framing may miss useful remedies.
What businesses can do before escalating
A measured response often works better than an emotional one. Before contacting the poster or filing a complaint, businesses should consider the following steps:
- Preserve all evidence in original form.
- Assess whether the statement is false fact, opinion, or a mixed statement.
- Check whether the content violates platform policy.
- Review the business impact and whether proof of loss exists.
- Consider whether a correction request, legal notice, or platform report is the best first step.
- Evaluate risk: a public dispute can sometimes amplify the content.
For some matters, a carefully drafted legal notice may resolve the issue without litigation. In others, civil claims, criminal complaint preparation, or negotiation may be more effective. The right path depends on the specific facts and the client’s risk tolerance.
How a reputation management lawyer in Thailand may help
In a section 423 case, legal support is often practical and evidence-driven. A reputation management lawyer in Thailand may assist with:
- reviewing evidence and identifying the strongest legal theory;
- assessing whether the content is false, defamatory, or policy-violating;
- drafting legal notices or response letters;
- building a platform reporting strategy for Google, Tripadvisor, Booking.com, Facebook, TikTok, YouTube, or marketplaces;
- preparing a civil claim based on damages and business loss;
- preparing a criminal complaint where sections 326 to 333 may be relevant;
- negotiating removal, correction, or settlement;
- evaluating litigation risk and likely escalation paths.
PimLegal’s role is typically to help clients choose the most effective route, not to promise a particular result. In reputation disputes, timing, documentation, and legal framing are often decisive.
What damages may look like in a civil case
Section 423 is civil in nature, so the focus is usually on loss and harm rather than punishment. Depending on the facts, a claim may seek compensation for business interruption, lost bookings, reduced sales, corrective marketing costs, or other provable consequences of reputational injury.
However, damages are not automatic. A claimant usually needs to connect the false statement to the harm using evidence rather than assumptions. This is one reason many businesses first seek a legal assessment before deciding whether to proceed.
Practical prevention tips for Thailand-based businesses
Businesses can reduce exposure by preparing in advance.
- Keep clear internal records for customer disputes and service incidents.
- Adopt a written response protocol for negative reviews.
- Train staff not to escalate arguments online.
- Monitor Google, Tripadvisor, Booking.com, and social channels regularly.
- Save evidence immediately when suspicious or false content appears.
- Use calm, factual public replies when a reply is appropriate.
- Seek legal review before accusing the poster of defamation publicly.
Prevention is especially important for hospitality, healthcare, beauty, legal services, agencies, and consumer brands, where trust is closely tied to online reputation.
