Court, arbitration or negotiation: pick the route first

Every cross-border dispute starts with the contract. If it contains an arbitration clause, the parties are generally expected to arbitrate rather than sue. If it does not, check the governing law and jurisdiction clauses, where the debtor actually holds assets, and how strong the paper trail is. Those three answers decide whether to begin with a formal demand letter, mediation or a filed claim.

Arbitration in Thailand and enforcing foreign awards

  • Arbitrations seated in Thailand follow the Arbitration Act B.E. 2545 (2002).
  • Common institutions are the Thai Arbitration Institute (TAI) of the Office of the Judiciary and the Thailand Arbitration Center (THAC).
  • Thailand is a party to the 1958 New York Convention, so awards from other contracting states can be enforced through a petition to the Thai courts, subject to the statutory grounds for refusal and filing deadlines.
  • Foreign court judgments are generally not directly enforceable in Thailand; a fresh Thai lawsuit is usually needed, using the judgment as evidence.

Lawful cross-border debt collection

Collection must respect the law where the debtor is located. In Thailand the Debt Collection Act B.E. 2558 (2015) prohibits threats, public shaming and contact at unreasonable hours. We assemble the evidence of debt, translate documents, send bilingual demand letters on law-firm letterhead, negotiate instalment plans and check limitation periods before claims expire. For debtors abroad we coordinate with local counsel case by case.

What to bring to the first consultation

  • Contract, purchase orders, invoices and proof of delivery
  • Emails or messages where the debtor acknowledged the debt (relevant to limitation)
  • Company certificates for both sides and a power of attorney (notarisation and legalisation may be needed if signed abroad)
  • A certified copy and translation of any foreign award or judgment you want enforced

Frequently asked questions

Can I sue in court if the contract has an arbitration clause?

The other party can ask the court to strike out the case so the dispute goes to arbitration. Have the clause reviewed before choosing a route.

Can a Singapore or Hong Kong award be enforced in Thailand?

Both are New York Convention jurisdictions, so a petition can be filed in the Thai courts within the legal time limit; the court may refuse on limited statutory grounds.

What does it cost and how long does it take?
