Accidents happen, but when they occur in a foreign country, the aftermath can be terrifying. Whether it’s a reckless motorbike driver in Phuket, a surgical error in a Bangkok hospital, or a slip-and-fall in a shopping mall, knowing your legal rights is the difference between financial ruin and fair compensation.
If you have suffered an injury due to someone else's carelessness, you may be searching for a negligence lawyer in Thailand. The Thai legal system operates differently from Western jurisdictions—damages are calculated differently, timelines are shorter, and "pain and suffering" is viewed through a distinct cultural lens. This guide breaks down the reality of Thai tort law in 2025, explaining exactly how to fight for what you are owed.

Understanding Thai Negligence Law (Section 420)
The foundation of all personal injury and negligence claims in Thailand is Section 420 of the Civil and Commercial Code. This is the "Wrongful Act" (Tort) law.
It states: "A person who, willfully or negligently, unlawfully injures the life, body, health, liberty, property or any right of another person, is said to commit a wrongful act and is bound to make compensation therefore."
To win a case, your lawyer must prove four distinct elements:
- Action: The defendant did something (or failed to do something they were obligated to do).
- Willfulness or Negligence: The action was intentional or due to a lack of reasonable care.
- Unlawfulness: The act violated your legal rights.
- Causation: The act directly caused your injury or loss.
What Constitutes a "Wrongful Act"?
In Thailand, a wrongful act is not limited to physical violence. It covers a broad spectrum of careless behaviors. If a hotel fails to fix a loose railing and you fall, that is a wrongful act. If a driver runs a red light and hits your car, that is a wrongful act.
The key legal test is "Reasonable Care." Would a reasonable person in the same situation have acted differently? If the answer is yes, you likely have a claim.
Common Types of Negligence Claims in Thailand
Foreigners most frequently encounter negligence in specific scenarios. Each requires a different legal approach.
Road Traffic Accidents
This is the most common source of litigation. Thailand has high road accident rates. Claims here often involve negotiating with insurance companies (which are notoriously difficult) and proving fault using police reports and CCTV footage.
Medical Malpractice
Suing a doctor or hospital in Thailand is challenging but possible. The Medical Council of Thailand often protects its own, so you need a specialized lawyer who is not afraid to challenge medical institutions. You must prove that the doctor deviated from the "standard of care" expected of a professional in that field.
Slip, Trip, and Fall (Premises Liability)
If you are injured on private property (like a mall or hotel) due to poor maintenance, the owner is liable. However, Thai courts expect you to watch where you are going. If the hazard was "obvious," your compensation might be reduced.
The Statute of Limitations: Don't Wait Too Long
Time is critical. Under Section 448, the clock is ticking.
- The General Rule: You must file a claim within 1 year from the day you became aware of the injury and the identity of the person who caused it.
- The Absolute Limit: You cannot file a claim more than 10 years after the accident occurred, regardless of when you found out.
- Criminal Cases: If the negligent act was also a crime (e.g., reckless driving causing death), the statute of limitations may be longer, following the Criminal Code.
Warning: Do not rely on verbal promises from insurance companies. If the 1-year deadline passes while you are "negotiating," you lose your right to sue forever.
Calculating Compensation: What Can You Claim?
Thai courts are compensatory, not punitive. This means they aim to cover your actual losses, not to punish the wrongdoer with massive multi-million dollar payouts like in the US.
Material Damages (Pecuniary)
These are easy to prove with receipts:
- Medical bills (past and future).
- Loss of earnings (if you cannot work).
- Property damage (repairing your car or motorbike).
Non-Material Damages (Non-Pecuniary)
This covers "pain and suffering" and loss of enjoyment of life. Thai judges are historically conservative here. You might receive 100,000 to 500,000 THB for serious injuries, but rarely millions unless the injury results in permanent disability.
Future Care Costs
If you require long-term nursing or rehabilitation, the court can award a lump sum or monthly payments to cover these future expenses.
The Role of Contributory Negligence
Thailand follows the doctrine of Contributory Negligence (Section 442). If you were partially at fault for the accident, your compensation will be reduced.
- Example: You were hit by a speeding car, but you were not wearing a helmet on your motorbike. The court may decide the driver is 80% at fault and you are 20% at fault. You will receive only 80% of the calculated damages.
Product Liability: Strict Liability Rules
If you are injured by a defective product (e.g., an exploding phone or faulty brakes), the Product Liability Act B.E. 2551 (2008) applies.
This law is more consumer-friendly. It imposes Strict Liability, meaning you do not need to prove the manufacturer was negligent—only that the product was defective and it caused your injury.
The Legal Process for Filing a Claim
- Evidence Collection: Gather police reports, medical records, and witness statements immediately.
- Demand Letter: Your lawyer sends a formal notice to the wrongdoer and their insurance company demanding compensation.
- Mediation: Most cases in Thailand go to court-supervised mediation first. This is faster and cheaper than a trial.
- Civil Lawsuit: If mediation fails, your lawyer files a complaint with the Court.
- Trial & Judgment: The judge reviews evidence and issues a verdict. There is no jury in Thailand.
Choosing the Right Negligence Lawyer
Not all lawyers are litigators. You need a firm with:
- Courtroom Experience: Ask how many tort cases they have actually taken to trial.
- Medical Experts: For malpractice, do they have access to independent doctors who will testify?
- English Fluency: You need to understand the strategy.
- Fee Structure: Many personal injury lawyers work on a contingency basis (success fee), but you usually have to pay court filing fees upfront.

Frequently Asked Questions
- Can I sue if I signed a waiver? Often, yes. Under the Unfair Contract Terms Act, waivers that completely exonerate a business from liability for injury or death caused by negligence are often void or unenforceable in Thai courts.
- How long does a lawsuit take? A typical civil case takes 1 to 2 years in the Court of First Instance. If the other side appeals, it can take another 2 to 5 years. This is why mediation is highly preferred.
- Do I have to be in Thailand for the trial? Usually, yes. While your lawyer can handle procedural hearings, you will likely need to appear in person to testify about your injuries and how they affect your life.
- Who pays the legal fees? In Thailand, each side pays their own lawyers. While the winner can ask the court to order the loser to pay "legal fees," the amount awarded is usually nominal and rarely covers the actual cost of a private international lawyer.
- Can I sue the government for bad roads? Yes, you can sue government agencies (like the Department of Highways) in the Administrative Court for negligence in maintenance. However, these cases are slow and require a very high burden of proof.
