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

286. What documents are required to legalize corporate papers at the UAE Embassy in Thailand?

Every certified file passes three hands: a native-speaking translator, a subject-matter reviewer, and the responsible attorney who signs the certification page. 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. Tell us where the document will be used and you will get a plan and a price the same business day.

561. How does a foreign-owned restaurant secure a direct sales and direct marketing business license?

Regional headquarters, IBC and industrial licence files move through several agencies at once, so we run them as a single plan with one named coordinator. 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. Tell us where the document will be used and you will get a plan and a price the same business day.

575. How do companies apply for an official green building certification (LEED/TREES) for commercial real estate in Thailand?

Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. 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. Tell us where the document will be used and you will get a plan and a price the same business day.

381. Can your agency register a global trademark through the Madrid Protocol?

Company name, director names and registered address are cross-checked across every document, because a single spelling mismatch triggers a rejection. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

405. Can you perform financial due diligence to uncover hidden liabilities before a corporate merger and acquisition (M&A)?

Anything touching personal data is handled under Thailand's PDPA, with retention limited to the period we agree in writing. 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.

268. How long does it take to translate specialized technical engineering manuals and IT software documents?

We route each file to the right credential: NAATI for Australia, Ministry of Justice registered translators for Thai court work, and embassy sworn translators for European destinations. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

343. Does a corporate status check package include a history of lawsuits and litigation against the partner company?

Accounting, tax, property and estate work for foreign nationals is run jointly with our auditors and lawyers so the translated file and the filed file always match. 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.

301. Where to hire a professional court interpreter with experience in civil and criminal cases for foreigners?

Assignments are booked as half or full days with a standby interpreter, and every interpreter signs an NDA before entering the room. 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.

548. Can a foreign labor employment legal consultant review expat employment contracts to ensure total compliance?

The whole workflow runs online, so clients abroad do not need to fly back to Thailand to sign every page. 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. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

516. What documents and timelines are involved when applying for Thai citizenship through a Thai spouse?

We provide an interpreter and an escort on the day itself, because the counter stage is where most applicants lose a trip.
