Statute of Limitations for General Personal Injury / Negligence in Thailand

Overview

Thailand’s rules for when a person must file a claim for general personal injury (often framed as negligence or another tort-like basis) are governed largely by the Thai Civil and Commercial Code (CCC). For everyday disputes—car accidents, workplace injuries, defective services, slip-and-fall incidents—most plaintiffs rely on the CCC limitations framework rather than criminal procedure timelines.

DocketMath’s statute-of-limitations calculator is designed to help you translate the rule into a concrete deadline once you know key dates (for example, the injury date and any relevant “when the claimant knew” facts). This post explains the main limitations period, the most common exceptions that can shift the filing deadline, and the exact statutory text to look up.

Limitation period

For general personal injury / negligence-type claims in Thailand, the standard limitations period under the CCC is typically 1 year.

What “1 year” means in practice

Most limitation regimes require counting from a triggering event. In Thailand’s general framework for obligations not specifically covered elsewhere in the CCC, the clock commonly runs from the point when the cause of action arises—often tied to the injury occurrence.

How the deadline can change

Even when a base period is 1 year, your real-world deadline may shift depending on:

• When the harm occurred (accident/injury date)
• When the claimant knew or should have known certain facts (in limited situations where the law ties accrual to knowledge)
• Whether the claim is characterized as something other than “general” personal injury (for instance, claims involving specific statutory schemes or particular types of obligations)

A practical way to think about it:

• If your claim is straightforward (single accident, immediate injury symptoms), you generally start from the injury date and count 365 days (subject to calendar counting rules).
• If symptoms emerge later or there are disputed knowledge facts, the timeline you enter into DocketMath should reflect the earliest plausible date the claim could be said to have accrued under the relevant CCC concept.

Key exceptions

Thailand’s CCC contains limitations provisions with nuances that can affect deadlines. The biggest practical differences typically come from (1) what type of obligation you are suing on and (2) whether the law treats the accrual point differently.

1) Claims that fall under different limitation categories

Not every injury-related lawsuit is treated as “general negligence.” Some claims may be framed around:

• Contractual obligations (which can have different limitation periods)
• Specific statutory duties (which may have their own timing rules)
• Other CCC provisions that set distinct periods based on the nature of the right

Practical effect: if the legal characterization changes, the base period you use in DocketMath may change.

2) Knowledge-based accrual arguments (where relevant)

In certain CCC limitations contexts, courts look to knowledge (or a claimant’s ability to know) rather than strictly the injury event date. This is especially relevant where:

• Symptoms were not apparent immediately, or
• The claimant could not reasonably identify the responsible conduct at the time of the incident

Practical effect: you may need two candidate dates—incident date and discovery/knowledge date—and test which one aligns with the limitation concept used for your claim.

3) Parties’ conduct and procedural posture

Some disputes involve delays caused by communications, negotiations, or attempts to resolve informally. Those facts do not automatically pause limitation periods, but they can matter for:

• When accrual is argued
• Whether a particular legal theory is used
• How the claim is supported procedurally

Statute citation

For general personal injury / negligence-type claims in Thailand, the key limitations rule is found in the Thai Civil and Commercial Code.

Commonly cited CCC limitations language for the general category provides a 1-year period for rights not subject to special periods elsewhere in the Code.

When researching the exact wording you can rely on, focus on:

• The CCC provisions on limitation periods (immediately adjacent sections in the CCC that establish 1-year and other time limits)
• Any subsections that explain when the period begins (accrual trigger) for the particular category

If you are using DocketMath, the calculator will align to the CCC’s general personal injury / negligence category with a 1-year limitation period as the default rule.

Use the calculator

DocketMath’s statute-of-limitations calculator helps you convert the CCC rule into a specific “latest filing date” based on the facts you enter.

Step-by-step: how to enter facts

1. Open the calculator: /tools/statute-of-limitations
2. Select jurisdiction: **TH (Thailand)
3. Choose the claim category that matches your situation:

   • “General personal injury / negligence” (default alignment with the CCC’s general 1-year concept)
4. Enter:

   • Incident/injury date
   • If you have one: knowledge/discovery date (only enter if it is genuinely relevant to how you believe the claim accrued)
   • Your intended filing date (optional, but useful for immediate pass/fail)

What the output tells you

After input, the calculator typically outputs:

• Calculated deadline (latest date you can file under the selected category)
• Time remaining / overdue status relative to your chosen filing date
• A clear breakdown of how the calculation changed if you switch the accrual date (incident date vs discovery/knowledge date)

How output changes when you change an input

To make this tangible, run two scenarios:

• Scenario A (incident-based):

  • Input accrual date = incident/injury date
  • Output deadline = incident date + 1 year

• Scenario B (knowledge-based):

  • Input accrual date = discovery/knowledge date
  • Output deadline = discovery date + 1 year

If Scenario B produces a later deadline, it reflects that the underlying theory you selected assumes later accrual. If the calculator does not allow knowledge-based switching for your chosen category, that’s a signal that the selected CCC category may be strictly event-based.
