In depth
Personal Injury, Consumer, Insurance & Administrative Cases: what foreign clients need to know
Tort and consumer claims require examination of the legal basis and evidence of loss. Preserve vulnerable evidence promptly; no universal first-week rule determines the outcome — scene photographs, medical certificates that record continuing symptoms, and receipts proving actual loss. We therefore start by helping the injured party capture and preserve that record before any negotiation with the other side or the insurer.
What Thai law lets you claim as damages
Recoverable heads include medical costs already paid and those still to come, income lost while recovering, property damage, loss of earning capacity where disability results, and mental suffering where the law allows it. Separating each head with its own supporting document is what gives the figure weight in negotiation and in court.
For family-funded travel or care, check who may claim, necessity, connection to the injury and payment evidence. A receipt alone does not assure reimbursement of every amount. Keeping a daily note of symptoms and days off work from the outset helps far more than reconstructing months later at the hearing.
Check consumer-case eligibility before choosing the procedure
A goods or services dispute must meet the legal definition of a consumer case. Fee exemptions, oral filing and specific proof rules have their own conditions; a purchase does not automatically establish every benefit. Court fees are distinct from professional fees and evidence-gathering costs.
Unsafe goods are covered by product-liability legislation: check the product category, responsible operators and the statutory proof conditions; a defect does not establish every seller's liability in all circumstances. The critical point is to preserve the item, its packaging and the proof of purchase — do not discard it or return it to the seller before taking advice.
Negotiating with an insurer without giving ground away
If symptoms are evolving, obtain medical views and estimates of continuing care. Check whether an offer is a partial payment or a settlement releasing specified rights; not every receipt of money ends every claim. Do not wait for treatment to end beyond prescription or policy-notification deadlines.
A road accident may involve compulsory protection and voluntary insurance if present. Check eligibility, terms, limits, notice deadlines and the effect of payments already made under the law and policies. Do not assume every counterparty has voluntary cover or every amount can be claimed twice. Reviewing cover does not guarantee additional recovery.
Cost structure: government fees vs professional fees
| Item | Official fee | Professional fee | Note |
|---|---|---|---|
| Case assessment and building the initial evidence set | Actual charges for police daily records and medical files | Contact our team for a quotation | Includes a head-by-head damages calculation for use with the insurer |
| Pre-litigation damages negotiation | No government fee at this stage | Contact our team for a quotation | Suited to cases where the other side is insured and liability is not the main dispute |
| Filing a consumer or tort claim in the court of first instance | Section18 eligibility and exceptions require review; ultimate liability for costs is not exempt. Ordinary tort fees depend on relief, rates and caps | Contact our team for a quotation | Cases needing medical or engineering experts carry additional witness costs |
Assessing an injury with continuing treatment
Situation: Assume an injured person receives a compensation offer while continuing treatment costs and income effects remain uncertain.
Assessment points: Obtain medical advice, distinguish evidenced losses from future estimates, and check release wording and filing deadlines without waiting until time expires.
Illustrative example; outcomes depend on the facts and the authority's decision.
Assessing an appliance after a house fire
Situation: Assume product remains, a receipt and fire information have been preserved, but causation and the responsible parties are disputed.
Assessment points: Preserve evidence safely and examine fire-origin findings, product use and the legal basis before choosing defendants and heads of loss. Damage after a fire does not itself prove the product caused it.
Illustrative example; outcomes depend on the facts and the authority's decision.
When to act, and when waiting is fine
The incident is recent and treatment is ongoing
Keep collecting evidence and review settlement terms while preserving deadlines; do not await recovery beyond the time limit
The other party is uninsured or denies responsibility
Assess potentially enforceable assets and competing rights; an asset check does not guarantee payment
The loss came from goods or a service you paid for
Check consumer-case eligibility, the claim basis and any issue-specific proof rules; lower overall costs are not assured
More than a year has passed since the incident
Take advice promptly: check knowledge of harm and the liable person and the applicable legal basis; do not apply incident date plus one year to every case

Documents in detail
| Document | Issued by | Certification / translation | Validity |
|---|---|---|---|
| The police daily record made on the day of the incident | The police station for the area where it happened | Ask for a certified copy, since the wording in that record usually becomes the starting point in the argument over negligence | Request promptly and retain the record date; it does not conclusively establish liability or replace a valid criminal complaint |
| The medical certificate and the full medical record | The treating hospital or clinic | It must state the nature of the injury, the recovery period, and an opinion on disability or long-term effect | Collect updates for every further treatment, because damages are computed across the whole course of care |
| Treatment receipts and proof of related expenses | Hospitals, pharmacies, and transport providers | Keep every original, including travel to treatment and the cost of a carer during recovery | Collect continuing and estimated future costs while taking timely steps to preserve legal rights |
| Evidence of income lost while recovering | The employer, or the income records of a self-employed claimant | Payslips, a letter confirming the leave taken, or bank statements for the self-employed | Choose a period appropriate to the occupation and dispute; no universal six-month minimum applies |
| The contract, receipts, and advertising claims in a consumer dispute | The business that sold the goods or supplied the service | Capture the advertisement pages and chat messages, since advertising claims can form part of the agreement | Keep them from the purchase date and preserve the defective item as physical evidence |
Timeline and who does what
| Stage | Owner | Duration | Detail |
|---|---|---|---|
| Secure the evidence immediately after the incident | You provide | Promptly, subject to safety and access to evidence | Preserve images and witness details and lawfully request retention of camera footage promptly. Retention varies by system; no universal fortnight applies. |
| Assess liability and quantify the damages | Handled by our team | Assess scope and urgent deadlines from the documents | We split the claim into treatment costs, lost income, non-pecuniary harm, and long-term effect, then weigh how far each side was at fault. |
| Negotiate with the other side or the insurer | Handled by our team | Depends on the parties and evidence; no settlement date is assured | Use medical evidence and a damages schedule in negotiation, checking settlement effects and deadlines. An increased offer or resolution without litigation is not assured. |
| File the claim in the court with jurisdiction | Handled by our team | Depends on service and the court hearing orders | Check classification and claimant eligibility under18, which does not exempt ultimate liability for costs. Exempted fees can be ordered under statutory circumstances; independently incurred expenses are not all waived. |
| Trial, judgment, and enforcement | Depends on the agency | Assess trial, appeal and execution separately against the actual case | Winning is not receiving: enforcement follows, and we map the judgment debtor's assets in advance. |
Common pitfalls
Signing the insurer's settlement in the first week, before the length of treatment is known
Review medical evidence and release wording together; do not let filing or insurance-notice deadlines expire
Letting the limitation period lapse, notably the one-year tort period running from knowing of the wrong and the wrongdoer
Record the date of knowledge at the outset and set a reminder three months before the deadline
Discarding or repairing the defective product, leaving no physical evidence of the defect
Keep the item as it is, photograph it from every side, and notify the seller in writing
Claiming only treatment costs and omitting lost income and non-pecuniary harm
Build a full schedule of every head of damage with supporting documents before making the demand
Doing it yourself vs working with us
| Aspect | On your own | With our team |
|---|---|---|
| The amount actually received | Usually accepts the insurer's first offer for want of a benchmark | Every head of loss is computed and compared with similar decided cases before negotiating |
| The burden of assembling documents | You chase the hospital and the police yourself while still recovering | Our team requests and follows up on the full set throughout |
| Dealing with the other side | Faces continuous pressure to settle by message and telephone | All contact routes through counsel, easing the pressure and preventing damaging statements |
| Getting paid after winning | Holds a judgment without knowing the enforcement steps | Assess enforceable property, competing creditor rights and relevant orders; neither asset discovery nor full payment is guaranteed |

FAQ
Frequently asked questions
Insurance won't pay — what now?
You can complain to the OIC or use its mediation, or sue directly within the limitation period.
Consumer suit — filing fee?
Section 18 of the Consumer Case Procedure Act B.E. 2551 exempts eligible consumers or authorised representatives from procedural court fees, but not ultimate liability for costs. The court may order all or part of exempted fees for unreasonable litigation or demands, improper conduct or unnecessary proceedings, delay or other circumstances it considers appropriate. A business claimant is not automatically exempt. Professional and evidence-preparation costs are separate.
Admin Court time limit?
Distinguish challenges to orders, administrative tort and administrative-contract claims, including any required administrative appeal, knowledge dates and exceptions. One deadline does not cover every request. Promptly provide the order, receipt evidence and appeal documents for legal assessment.
Uninsured counterparty?
Check compulsory cover and the statutory conditions for the road-victims fund; absence of insurance does not make the fund pay every loss. Counterparty liability and litigation rights require separate assessment.
Class action in Thailand?
Yes, under the class-action chapter added to the Civil Procedure Code in 2015.
Does the business bear proof of every issue?
No. Section29 shifts only issues the court considers within the business party's exclusive knowledge, such as production or services, not every issue or damages automatically. Check section3 classification first. Oral or written filing is under section20; an officer records an oral claim for signature. An unsafe-product injured person need not personally be the purchaser.
What must an unsafe-product claimant prove and which limitation rules apply?
Sections5–6 require assessment of statutory operators, a sold product, damage from it and ordinary use or storage. Intention, negligence and which operator's act caused harm need not be proved, but section7 defences remain. Damage to the unsafe item itself is excluded under this Act; other rights may exist. Section12 ordinarily uses three years from knowledge of damage and the liable operator, or ten years from sale. Accumulated-substance and delayed-manifestation injuries have special rules, not a universal sale-date cutoff.
What is the limitation period for a tort claim?
CCC448 generally uses one year from knowledge of the wrong and the person liable, or ten years from the act. Paragraph two applies a longer criminal prescription period where the damages arise from a criminal act with that longer period. Product-liability and insurance claims may follow different rules; one year does not govern every right.
Can medical costs be claimed without receipts?
It is harder, but medical records and certificates can still support the claim; request a full copy from the hospital.
Does the claimant's own carelessness reduce the award?
Assess CCC442 together with223, considering the circumstances and each side's contribution to the harm. Neither a nonzero award nor a fixed apportionment is assured in every case.
Is a lawyer required to file a consumer case?
You may file in person under the statutory procedure. Counsel can assess rights and organise evidence but does not assure a better result or success.
