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.

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.

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

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.
