Dernière mise à jour :
Thailand records some of the highest road-fatality numbers in the world, and a disproportionate share of the victims are on two wheels. When a foreigner is killed here, or a foreign family loses a Thai relative, the first question is almost never about the criminal case. It is about money: who is allowed to sue, and for how much. A wrongful death claim in Thailand is narrower than most people assume, and it depends on legal relationships rather than on grief.
Two Supreme Court decisions published in October 2026 make the point sharply. In one, a father recovered 800,000 baht for the loss of his daughter’s support only because a late marriage had made her his legitimate child. In the other, an insurer that paid out above its policy limit turned round and recovered the excess from its own insured. This guide sets out who can claim, what the Civil and Commercial Code allows, and the deadline that quietly ends most claims.

What a Wrongful Death Claim in Thailand Covers
There is no separate Thai statute on fatal accidents. A wrongful death claim in Thailand is an ordinary tort claim under Section 420 of the Civil and Commercial Code, with Section 443 adding the heads of damage that apply when the victim dies. Where a vehicle is involved, Section 437 shifts the burden onto the person in control of it, who is liable for damage caused by the vehicle unless he proves the damage arose from force majeure or the fault of the injured person.
Fault is still apportioned. Section 442, applying Section 223, reduces the award where the victim contributed to the accident: riding without a helmet, crossing against the light, or driving after drinking all cut the figure. The civil case runs alongside any criminal prosecution for causing death by negligence, and where the driver has been tried, the civil court deciding a claim connected with the offence must accept the facts found in the criminal judgment (Criminal Procedure Code section 46), so a conviction for causing the death usually settles the driver’s fault. Our general guide to the aftermath of a crash is at conseils juridiques après un accident en Thaïlande.
Who Can Sue, and Who Cannot
Two distinct sets of claims arise on a death, and they belong to different people.
- Claims that belonged to the deceased: medical bills and lost earnings where death was not instantaneous, and property damage. These form part of the estate under Sections 1599 and 1600, and are pursued by the heirs or by the court-appointed estate administrator.
- The loss-of-support claim: this one is personal to the dependant. Section 443 paragraph 3 gives it to a person who was deprived of support that the deceased owed him by law.
That phrase decides everything. The duty must exist in the Code, not merely in fact. A spouse qualifies under Section 1461, a legitimate child under Section 1564, and a parent under Section 1563, which obliges a legitimate child to maintain his parents.
Who does not qualify is the harder lesson. An unmarried partner of twenty years has no statutory right to support, however complete the financial dependence. Nor does the father of a child he never legitimated: the duty under Section 1563 runs from a legitimate child only. Supreme Court 6436/2562 is the clean illustration, and the mechanism is explained in our companion article on the legitimate child in Thailand.
The 6436/2562 example
A young woman was killed as a motorcycle passenger on 3 April 2016. Her parents had lived together without registering a marriage, so she was illegitimate and her father was, in law, a stranger to her. On 3 May 2016 the parents married. An arbitrator awarded the father 800,000 baht plus interest for loss of support, and the insurer sought to set the award aside under Section 40 of the Arbitration Act B.E. 2545 as contrary to public order. The Supreme Court refused: Section 1557 made the daughter legitimate from birth, so the duty of support had existed all along and the father’s loss was a real one.
What You Can Recover Under Sections 443 and 445
| Head of damage | Base juridique | How it is assessed |
|---|---|---|
| Funeral and other necessary expenses | CCC s.443 para 1 | Actual reasonable cost, on receipts. Temple and cremation costs are routinely allowed. |
| Medical expenses and lost earnings before death | CCC s.443 para 2 | Only where death was not immediate. Hospital invoices and proof of income. |
| Loss of lawful support | CCC s.443 para 3 | Monthly figure multiplied by a period the court considers reasonable, taking the dependant’s age and the deceased’s earning capacity into account. |
| Loss of a third party’s right to the deceased’s work | CCC s.445 | Available where the deceased was bound by law to perform work for that person. |
| Grief or bereavement as such | No general provision | Not recoverable. Section 446 covers non-pecuniary harm to the person injured, and does not create a bereavement award for relatives. |
The absence of a bereavement award is the single biggest difference from the common-law systems most expatriate families come from. Thai awards for loss of support are also modest by Western standards, because they track the deceased’s actual earning capacity in Thailand rather than a notional lifetime multiplier. Our plain-English note on how courts quantify compensation is at damages under Thai law.
Where the deceased owned assets in Thailand, the estate and the tort claim must be handled together, because the administrator is usually the person who has to bring the estate’s half of the case. The sequence is set out in our Guide des successions en Thaïlande pour les étrangers.
Compulsory Insurance, Policy Limits and the Real Defendant
Every registered vehicle must carry compulsory motor insurance, known as Por Ror Bor, under the Protection for Motor Vehicle Accident Victims Act. It pays a preliminary sum quickly, without waiting for fault to be decided, and a larger sum once the victim is shown not to have caused the accident.
| Por Ror Bor payment | Indicative amount per person |
|---|---|
| Preliminary medical expenses, no fault finding needed | up to 30,000 baht |
| Preliminary payment on death or dismemberment | 35 000 bahts |
| Medical expenses once the victim is shown not at fault | up to 80,000 baht |
| Death or permanent disability once liability is established | up to 500,000 baht |
Treat those figures as indicative and confirm the current schedule with the regulator, the Office of Insurance Commission, because they are set by subordinate legislation and have been raised more than once. Por Ror Bor is a floor, not a settlement: it almost never covers a genuine loss-of-support claim, and accepting it does not release the driver from the balance.
The reverse risk falls on drivers and employers. In decision 502/2569, published in the Supreme Court database on 7 October 2026, an employee’s truck damaged two separate third parties in one accident, another truck and a house. The policy covered third-party property damage up to 600,000 baht; the insurer paid 751,400 baht and recovered the 151,400 baht excess from the driver and the insured employer, who was jointly liable for his employee’s negligence. We analysed that case in insurance policy limits in Thailand. If you employ drivers here, the policy limit is the insurer’s ceiling, not yours.
The One-Year Deadline Under Section 448
Section 448 bars a tort claim one year from the day the injured party knew of the wrongful act and of the person liable, and in any event ten years from the act itself. Where the act is also a criminal offence carrying a longer prescription period, that longer period applies to the civil claim.
One year passes very quickly when a family is abroad, waiting on a police file, arranging repatriation and then dealing with probate. Two practical warnings. First, the clock runs from knowledge, not from the conclusion of the criminal case, so waiting for the verdict is a common and expensive mistake. Second, where the claim has to be brought by an estate administrator, the court appointment itself takes months and must be started early.
Building a Wrongful Death Claim in Thailand: Practical Steps
- Obtain the police accident report, the death certificate and the autopsy report. These are the backbone of both the criminal and the civil file.
- Identify every potential defendant: the driver, the vehicle owner, the employer if the driver was on duty, and both insurers.
- Prove the legal relationship. Marriage certificate, birth certificate plus evidence of legitimation, or the court order. Without it the loss-of-support claim fails at the first hurdle.
- Document the dependency: remittance records, bank statements, school fees, rent paid. Courts award what is proved, not what is asserted.
- Claim the Por Ror Bor preliminary payment immediately, in writing, while reserving the balance of the claim.
- Start the estate administration application in parallel, and diary the Section 448 deadline from the date of the accident.

Foire aux questions
Who actually brings a wrongful death claim in Thailand?
Two parties, often at the same time. The estate administrator or heirs bring the claims that belonged to the deceased, while each dependant who was legally entitled to support brings his own loss-of-support claim under Section 443.
Can an unmarried partner claim loss of support?
No. Section 443 requires a duty of support imposed by law, and Thai law imposes none between unmarried partners. Registering the marriage, or legitimating a child, is what creates the claim.
Can the family claim damages for grief?
Thai law provides no general bereavement award. Section 446 covers non-pecuniary harm suffered by the injured person, not the suffering of surviving relatives, so recovery is limited to funeral costs, pre-death losses and loss of lawful support.
How long do we have to sue?
One year from knowing of the wrongful act and the person liable, under Section 448, and in any event ten years from the act. A longer criminal prescription period can extend it. Do not wait for the criminal verdict.
Is the compulsory insurance payout the end of the matter?
No. Por Ror Bor is a minimum. Accepting it does not release the driver, the owner or the employer from the balance of a proven claim, and a release should never be signed without advice.
Can a foreign family sue in Thailand for a death that happened here?
Yes. Thai courts hear tort claims arising from accidents in Thailand regardless of the parties’ nationality. Heirs abroad usually act through a Thai lawyer under a power of attorney, with documents translated and legalised.
