In depth
Civil Litigation — Contract Breach & Damage Claims: what foreign clients need to know
Civil outcomes depend on the law and admissible evidence, including documents, testimony and other evidence. The work that determines the result happens before filing: lining the chronology up against every document, naming the allegations that still lack support, and testing which assets would actually satisfy a judgment. We therefore begin by reading the whole bundle and telling the client plainly whether the claim is worth running.
Reading the claim first: value, limitation and the assets at the end
Assess three matters before filing without letting a legal deadline expire. First, the claim value that documents can prove, not the figure the client feels wronged by. Second, the date limitation began to run, which differs by cause of action — contract, tort and instruments each run their own clock. Third, the counterparty assets still traceable today. If the third is empty, winning may yield only an uncollectable judgment.
With those settled, we cost out three routes side by side: full litigation, a negotiated exit driven by a demand letter with real weight, or writing the loss off and closing the matter. Many clients pick the second once they see cost against realistic elapsed time, and saying so is more honest than accepting every file that walks in.
The evidence stage is where cases change hands
Under CPC section104, the court assesses relevance and sufficiency of evidence; documents do not automatically outweigh testimony. Authenticity, provenance and consistency require examination. We therefore bundle evidence by issue in dispute rather than by the order it reached us. Each bundle carries a cover sheet naming the issue it proves and the gap it leaves. That exposes our own weak points before opposing counsel finds them.
Preparing witnesses is not rehearsing lines; it is drilling them to speak only to what they personally observed and to say they do not know when they do not. A witness who fills gaps by guessing is usually broken in cross-examination, and that damage spreads to every other point the same witness gave.
Interim measures and planning execution in advance
Where there is credible reason to think the other side will move assets while the case runs, consider the interim remedy available for that case and requested relief; a transfer alone does not ensure an order or preservation of all assets. Such applications demand strong evidence and usually security for damages, so we assess whether the outcome justifies the deposit before applying.
In parallel, we prepare execution while the trial runs rather than waiting for finality. Asset lists, security registrations and co-owner names are checked in advance, so that on the day the writ issues we can assess property rights and relevant orders before requesting execution, without treating a writ as an assurance of payment.
Cost structure: government fees vs professional fees
| Item | Official fee | Professional fee | Note |
|---|---|---|---|
| Case assessment and pre-filing opinion | No government fee | Contact our team for a quotation | Assessment scope and engagement terms are stated in the quotation |
| Filing a first-instance civil claim | Court filing fees run as a percentage of the claim value, subject to the statutory ceiling | Contact our team for a quotation | We quote the filing fee as a figure before the filing date |
| Pre-judgment protective application | Application fee at the set rate, plus security for damages as the court directs | Contact our team for a quotation | Requires solid evidence of asset dissipation |
| Appeal or Supreme Court petition | Fees at each level are calculated on the value still in dispute | Contact our team for a quotation | We say plainly whether the grounds can realistically reverse the result |
Assessing a supply-debt claim
Situation: Assume a manufacturer has three unpaid invoices. Delivery dates, due dates and the buyer's objections require separate review.
Assessment points: Organise evidence invoice by invoice, assess prescription and compare negotiation with filing without allowing legal deadlines to lapse.
Illustrative example; outcomes depend on the facts and the authority's decision.
Assessing a claim against an inactive company
Situation: Assume the counterparty has stopped trading and identified assets are encumbered. Company status, asset value and competing creditor rights need separate checks.
Assessment points: Check registers and encumbrances, compare costs with execution prospects, and examine rights that could be lost before choosing negotiation or not filing.
Illustrative example; outcomes depend on the facts and the authority's decision.
When to act, and when waiting is fine
File at once when limitation is close
Assess CCC sections193/14–17 for the claim filed. Withdrawal, abandonment or certain final dismissals may mean prescription was never interrupted; check that effect before ending proceedings to negotiate.
Negotiate first when the counterparty still has cash flow and ongoing trade
Check debt admission, signatory authority and enforceable security. A payment schedule is not assured to be faster than litigation or to yield full payment.
Seek protective measures when assets start moving out
Preserve transfer and ownership evidence. A shareholder change is not necessarily a transfer of company assets; the requested protective remedy must satisfy its legal conditions.
Assess options when no enforceable assets have been identified
Consider the relief sought, prescription, rights at risk and prospects of later asset discovery; one asset search does not justify abandoning every claim.
Documents in detail
| Document | Issued by | Certification / translation | Validity |
|---|---|---|---|
| The disputed contract with every annex | Both contracting parties | No certification, but the original must be available for the court at the evidence hearing | No expiry — the signing date governs |
| Proof of every payment or transfer made | The bank holding the account | Request a bank-stamped statement to pre-empt authenticity objections | Must span the whole disputed period |
| Demand letter plus its delivery record | Your lawyer or you directly | Send by registered post and keep the return receipt as documentary evidence | Check whether demand is required for this obligation. A unilateral letter does not interrupt prescription; do not wait beyond the filing deadline |
| Company affidavit of the opposing party | Department of Business Development | Must be a registrar-issued copy, not a screenshot from a website | Check current authority and company status when used; no universal six-month validity rule applies |
| Power of attorney appointing counsel | Signed by you on the court's prescribed form | Authorised director's signature plus company seal when the plaintiff is a company | Valid for the whole case at that court level |
Timeline and who does what
| Stage | Owner | Duration | Detail |
|---|---|---|---|
| Prescription and merits assessment | Handled by our team | Once the documents are complete; the timeframe is stated in the quotation | We read the full file, pin down the cause of action, measure the remaining prescription window, and judge whether a judgment could actually be enforced. |
| Assemble the documents listed above | You provide | Once the documents are complete; the timeframe is stated in the quotation | The sooner originals arrive, the less room the other side has to attack authenticity during the evidence stage. |
| Draft the complaint and compute court fees | Handled by our team | Once the documents are complete; the timeframe is stated in the quotation | We size the claim precisely because the claim value drives both the filing fee and whether jurisdiction sits with the district or provincial court. |
| File suit and serve the summons | Depends on the agency | Depends on service arrangements and court orders; no first-hearing date is assured | If service fails, check the address and seek an authorised method under the law and court directions; posting or publication is not automatic. |
| Evidence hearings and judgment | Depends on the agency | Assess the issues, evidence and hearing calendar, without a generic month range | We prepare witnesses in advance, file the witness list on time, and report every hearing to you in writing. |
| Enforce the judgment | Handled by our team | Check the compliance command, payment period and any stay or suspension; finality is not universally required | Assess enforceable assets, competing rights and orders before proceeding with the Legal Execution Department. Asset discovery and full recovery are not guaranteed. |
Common pitfalls
Counting prescription solely from learning a name, or applying one period to every cause of action
Have us fix the start date from the actual documents before deciding to keep negotiating
Misstating the claim value, filing in the wrong court, and having to start over
Separate principal, interest, and damages before computing the value
Winning but recovering nothing because the defendant holds no assets in their own name
Trace assets before filing and consider provisional measures to freeze them early
Submitting illegible copies that the court may decline to admit
Scan at high resolution and bring originals for inspection at the hearing
Negotiating alone and inadvertently acknowledging a debt or waiving rights in writing
Let counsel review every message or letter before you reply
Doing it yourself vs working with us
| Aspect | On your own | With our team |
|---|---|---|
| Prescription check | Usually counted from the default date, which may not be the date the law uses | We rebuild the timeline from documents and state the last safe filing date in writing |
| Hidden costs | A miscalculated filing fee must be topped up mid-case and hearings get rescheduled | We quantify filing, service, and enforcement costs up front |
| Witness preparation | Witnesses drift off point and lose weight under cross-examination | We rehearse issues and question order with each witness |
| After winning | Unfamiliar seizure procedure turns the judgment into paper only | Prepare execution against the command and compliance period, check stays or suspension without universally awaiting finality, and calendar section274 for the actual obligations and assets |
FAQ
Frequently asked questions
How is the court fee calculated?
Ordinary money claims pay 2% on the part up to THB 50 million, capped at THB 200,000, plus 0.1% of any excess, per Schedule 1 of the Civil Procedure Code; some cases, such as consumer claims, may be exempt.
Will I actually collect after winning?
Depends on the debtor's assets — we run asset tracing and enforcement.
Defendant in another province?
File where the defendant resides or where the cause arose — we can coordinate cases in other provinces.
Pre-suit mediation possible?
Yes, through court-annexed pre-suit mediation or other mediators; it can preserve the relationship, and any time saved depends on both parties.
Bond for appeal?
Separate appeal fees from a stay under CPC231: filing an appeal does not itself stay execution, and security depends on the procedure and court order. CPC234 challenges to refusal to admit an appeal have separate deposit or security requirements; not every losing defendant must secure the judgment debt for an ordinary appeal.
Do documents always outweigh testimony?
No. CPC104 gives the court authority to assess relevance and sufficiency, not a universal documentary hierarchy. Admissibility, authenticity, provenance and objections must also be assessed.
Does withdrawal preserve the interruption of prescription?
CCC193/14(2) addresses interruption by filing, but193/17 may treat it as never occurring after withdrawal, abandonment or final dismissal. The60-day refiling provision is limited to paragraph two's conditions, not every withdrawal. Under193/15, a new period begins when the interruption event ends, not universally at filing.
Does an asset transfer automatically permit interim attachment?
Check CPC254–255. A254 application is made with the complaint or before judgment in qualifying cases, excluding small claims. The court must be satisfied that the claim has merit and sufficient grounds exist. Section255(1) addresses intended dissipation obstructing enforcement or prejudicing the claimant, and other necessity considered just and appropriate by the court. Not every transfer warrants an order.
How long does a first-instance civil case take?
Case type alone cannot establish an assured timeline. Service, disputed issues, witnesses, court dates, appeals and execution are separate stages; counsel assesses the actual file and calendar.
Can filing fees be recovered from the losing side?
The court may order the loser to bear costs, but that rarely covers your full legal fees.
What happens if the defendant files no defence?
The court may proceed in default, but we still must prove the claim's allegations by evidence.
Can counsel be changed mid-case?
Yes, by filing a withdrawal and fresh appointment; we take the existing file to keep the issues continuous.
