International Document Services

Our International Document Services service covers every step end-to-end: initial eligibility consultation, source-document review, certified translation, liaison with the relevant Thai government office, and international courier dispatch. The handling team includes attorneys registered as Notarial Services Attorneys with the Lawyers Council of Thailand, translators recognized by the Ministry of Justice, and consular liaison officers with 10+ years of experience. Every document carries a different downstream use case — employment, study, immigration, marriage, or commercial filing — and each receiving authority has its own acceptance rules. We plan the shortest and most cost-effective document routing for your case before any fees are charged, and we issue a written timeline so you can schedule your travel or filing with confidence. Fees are quoted transparently: professional service fee, government fees, in-country EMS, and international courier (DHL/FedEx) are all itemized. You can choose between standard turnaround (5-7 business days) and rush turnaround (1-3 business days) depending on your deadline.

Cross-service questions, answered by the NYC Legal team

599. How do companies secure approval for importing specialized industrial machinery duty exemptions via BOI?

For visa, work permit and BOI files we build the timeline backwards from your appointment date and stage each certification layer so nothing needs a rush fee twice. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

551. Can a multinational corporation set up a Regional Operating Headquarters (ROH) or regional branch office in Thailand?

Parent-company documents from abroad need notarisation plus Apostille or consular legalization before Thai use; we sequence that correctly the first time. Indicative fees: certified translation THB 500–800 per page, consular legalization from THB 400 per stamp, Notary Public from THB 1,500 per signature — always quoted in full before we start. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

498. Do you offer a door-to-door service to get a Certificate of Single Status, notarize it, and DHL it to Australia?

Electronic documents must be traceable to their source, so deliverables ship with an audit trail whenever the receiving party asks for one. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Tell us where the document will be used and you will get a plan and a price the same business day.

391. What documents do Thai citizens need to apply for a Permanent Account Number (PAN Card) for financial transactions in India?

Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Tell us where the document will be used and you will get a plan and a price the same business day.

506. Does international express courier delivery via DHL or FedEx for legal documents include tracking and damage insurance?

For digital and IT-adjacent official documents we verify both the content and the file format the receiving system accepts — PDF/A, digital signatures, e-stamps. If the receiving authority rejects a file for a reason attributable to our work, we correct and re-file it at no additional professional fee. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

524. Where can I hire a turnkey team of multilingual hosts and conference interpreters for international summits?

Interpreters are matched to the setting: court and police station, government and embassy, medical, simultaneous booth work, and remote VRI/OPI. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Tell us where the document will be used and you will get a plan and a price the same business day.

542. Up to how many months of severance pay can a foreign employee claim under Thai labor law in cases of unfair dismissal?

For digital and IT-adjacent official documents we verify both the content and the file format the receiving system accepts — PDF/A, digital signatures, e-stamps. If the receiving authority rejects a file for a reason attributable to our work, we correct and re-file it at no additional professional fee. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

259. How much are the fees for a Notary Public attorney in Bangkok to authenticate a signature on a sales contract?

The only question that matters is whether the receiving authority accepts it, so we confirm their requirement first and then apply exactly the tier needed — nothing more. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Tell us where the document will be used and you will get a plan and a price the same business day.

383. Is there a turnkey package for foreign investors covering company setup, BOI, visas, and work permits?

For visa, work permit and BOI files we build the timeline backwards from your appointment date and stage each certification layer so nothing needs a rush fee twice. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Tell us where the document will be used and you will get a plan and a price the same business day.

416. Can a lawyer file a court petition to appoint an estate administrator for foreign heirs not residing in Thailand?

Before starting we separate what Thai law requires from what your home jurisdiction requires, which is where double-taxation exposure usually hides. If the receiving authority rejects a file for a reason attributable to our work, we correct and re-file it at no additional professional fee. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.
