Which documents are required for Arbitration Agreement?

Document set for Arbitration Agreement

Prepare the original or an officially certified copy, a full and faithful translation where the receiving language differs, identity documents for every named party, and any authorisation letter. Photocopies without a certifying seal are the single most common cause of a returned file.

Keep names spelled identically across the passport, the source document and the translation. A transliteration difference of one letter is treated as a different person.

How legal and judicial document translation works

Since 22 December 2024 Thailand is a party to the Apostille Convention, so for member states a single Apostille from the Department of Consular Affairs replaces the old embassy leg. For non-member states the full legalisation chain still applies.

Legal translation is judged on traceability, not style. A court judgment, an arbitral award or a power of attorney has to be translated so that every case number, party name, date and operative clause maps one-to-one onto the source, because the receiving authority reads both side by side.

Thai courts and agencies issue certified copies with their own seal. Translations are attached to that certified copy, never to a plain photocopy, and the translator's certification page is what the Department of Consular Affairs stamps.

Where Arbitration Agreement fits in the document chain

Documents connected with Arbitration Agreement move through a fixed chain: issuance, translation, certification and acceptance. Each link is verified against the previous one, which is why a missing intermediate stamp cannot be repaired at the final counter.

Because court judgments, contracts, powers of attorney and mutual legal assistance papers is assessed on paper, the safest working method is to prepare the complete set before approaching any office, then submit once with everything attached.

Evidence the reviewing officer looks for

An officer checks four things: that the original is authentic and current, that the translation is complete, that the certifications appear in the correct order, and that the person submitting is entitled to do so.

None of those four is a formality. A file that satisfies three of them is still returned, and the queue restarts from the beginning.

Working with IVC

IVC has handled court judgments, contracts, powers of attorney and mutual legal assistance papers since 2011 - more than fourteen years of files across translation, notarisation, consular certification and submission support. We prepare, check and track the chain; the decision always remains with the authority, and we never promise an outcome.

Fees depend on document type, language pair, volume and urgency, so they are quoted by our staff rather than published. Contact us by phone, LINE or email with a scan of the document and the destination, and you will get a written scope before anything starts.

Pre-submission checklist

• Carry identity documents for every named party and for the representative
• Keep receipts and reference numbers for each stage
• Scan the complete file exactly as submitted
• Allow for public holidays at each office in the plan
• Confirm in writing what the receiving authority accepts today
• Use the certified original or an officially sealed copy, never a plain photocopy
• Match the spelling of every name to the passport, letter for letter

Common pitfalls

• Relying on an outdated checklist instead of the issuing authority's own page
• Submitting through a representative whose authority has expired
• Letting a passport change break the match with an issued document
• Splitting a document set between offices and losing an intermediate stamp
• Treating one authority's acceptance as binding on another
