insurance policy limit in Thailand is the number most drivers never read until the day it matters. A Type 1 motor policy looks comprehensive, and then a single crash produces two separate victims, two separate repair bills, and a total that walks straight past the figure printed on the schedule. The question nobody asks in advance is simple: once the insurer has paid more than it promised, who owes the difference?
The Supreme Court answered that in Supreme Court decision 502/2569, a 2026 ruling from a small claims case in Nakhon Pathom. The insurer paid 751,400 baht against a 600,000 baht limit, then sued its own policyholder and his driver for the 151,400 baht of overpayment. It won, and the limitation period that applied was ten years, not one.

What an Insurance Policy Limit in Thailand Actually Covers
Voluntary motor insurance in Thailand is sold in tiers, and the headline tier, Type 1, covers damage to your own vehicle plus liability to third parties. The liability cover is capped. The cap is usually expressed per occurrence, not per victim, and that distinction is where the trouble in this case began.
Compulsory motor insurance under the Protection for Motor Vehicle Accident Victims Act sits underneath the voluntary policy and pays limited sums for bodily injury. It does not pay for a damaged house or a damaged truck. For property damage you are relying entirely on the voluntary policy, and only up to its limit. If you are still deciding what to buy, our guide on choosing insurance in Thailand sets out the tiers.
Nothing in a policy limit stops a victim from suing you for the rest. The limit binds the insurer, not the injured party. Your liability in tort under section 420 is whatever the court assesses, and the policy simply funds part of it.
Dika 502/2569: One Crash, Two Victims, 151,400 Baht Over the Limit
An employee was driving his employer’s truck in the course of his work on 30 September 2019. He rear-ended another truck, and the impact pushed his vehicle into a roadside house. One moment of inattention, two unrelated victims: the owner of the other truck and the owner of the house.
The employer had insured the truck under a Type 1 policy with third-party property cover of 600,000 baht per occurrence. The insurer paid every claim as it arrived.
| การชำระเงิน | วันที่ | Amount (baht) |
|---|---|---|
| Towing the insured truck | 24 Dec 2019 | 12,500 |
| Repairing the other truck | 30 Jan 2020 | 280,000 |
| Loss of use of the other truck | 3 May 2020 | 45,000 |
| Household contents | 26 Dec 2019 | 33,900 |
| Repairing the house | 13 Aug 2020 | 380,000 |
| Total paid | 751,400 | |
| Policy limit | 600,000 | |
| Excess claimed back | 151,400 |
The small claims court at Nakhon Pathom dismissed the insurer’s claim. The Court of Appeal for Region 7 reversed and ordered the driver and the employer to repay the 151,400 baht. The Supreme Court agreed with the outcome and changed only the interest rate.
One argument the defendants ran is worth noting because it is the instinctive one. They said the excess should be attributed to one victim’s claim rather than the other’s, so that at least part of the payout stayed inside the cover. The court refused to split it. The damage came from one incident at one moment, so the payments formed a single pool measured against a single per-occurrence limit.
Why the Court Used Management of Affairs, Not Subrogation
An insurer that pays a claim normally steps into the victim’s shoes. That is subrogation, and it carries the victim’s rights and the victim’s deadlines with it. Here the insurer was not standing in anyone’s shoes, because the victims had already been paid in full and had nothing left to assign.
Instead the court applied section 401 of the Civil and Commercial Code, management of affairs without mandate. By paying the victims, the insurer discharged a debt the driver and the employer owed in tort. Nobody asked it to pay the extra 151,400 baht, but the payment produced exactly the result the defendants would have wanted, which is the test section 401 applies. That creates an obligation to reimburse.
The practical consequence is blunt. The insurer did not need a clause in the policy entitling it to claw back an overpayment. The Code supplied the right.
The Limitation Trap: One Year or Ten?
Thai tort claims expire one year after the injured person knows of the wrongful act and the wrongdoer, under section 448 paragraph 1. Had this been a subrogated tort claim, the insurer would have been out of time long before it filed, since the last payment was made in August 2020.
Because the claim arose from management of affairs rather than tort, no specific limitation rule applied. The residual ten-year period in section 193/30 governed instead, running from the point the insurer could first enforce the debt. The suit was comfortably in time. Our note on limitation periods in Thai law explains how these periods interact.
For a policyholder this is the uncomfortable part. The exposure does not quietly disappear after a year. It can sit there for a decade.
What This Means If You Drive in Thailand
Expats tend to assume that comprehensive cover ends the conversation. Dika 502/2569 shows it does not. Three risks are worth naming.
- Per-occurrence caps are shared. One accident with several victims draws on a single limit, and the victims are not ranked.
- An insurer can pay first and recover later. Paying a claim above the limit is not a waiver of the limit.
- Employers carry the driver’s liability. The employer here was liable alongside the employee because the crash happened in the course of employment. Companies that let staff drive should read the limit on the fleet policy as a business risk, not an administrative detail.

How to Check Your Own Cover Before It Is Tested
- Find the third-party property damage figure on your policy schedule and confirm whether it is per occurrence or per claim.
- Check whether the figure is realistic against what you actually drive past: a pickup, a shopfront and a parked car in one incident is not an exotic scenario.
- If the vehicle is company-owned, confirm the policy names the company and covers employees driving on company business.
- Keep every payment advice the insurer sends you. If it later claims an overpayment, the dates and amounts decide the arithmetic.
- Ask your insurer in writing what it does when payouts exceed the limit. The answer is now predictable, but you want it on file.
คำถามที่พบบ่อย
What is an insurance policy limit in Thailand?
It is the maximum the insurer will pay under that head of cover, usually expressed per occurrence for third-party property damage. It caps the insurer’s obligation, not your liability to the person you injured.
Can my insurer make me repay what it paid above the limit?
Yes. In Dika 502/2569 the Supreme Court allowed recovery of 151,400 baht under section 401 of the Civil and Commercial Code, treating the overpayment as management of affairs without mandate.
How long does the insurer have to claim the excess back?
Ten years under section 193/30, not the one-year tort period in section 448. The claim is for reimbursement of money advanced, so the tort limitation does not apply.
Does the limit apply separately to each victim?
Not where the policy sets a per-occurrence limit. The court in Dika 502/2569 refused to allocate the excess to one victim, because the damage flowed from a single incident.
Is my employer liable if I crash a company car in Thailand?
An employer is liable for an employee’s wrongful act committed in the course of employment, and in this case the employer was ordered to repay the insurer alongside the driver.
Should I raise my third-party property cover?
That is a commercial decision rather than a legal one, but this ruling shows that the gap between the limit and the real loss lands on you, and can be enforced for ten years.
