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

409. Do you provide corporate tax planning consulting to avoid double taxation for multinational export companies?

Cross-border wills and estates must be read against the destination jurisdiction, and we coordinate local counsel where that is required. 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.

355. Do you offer Non-O family and spouse visa services for dependents of expats working in Thailand?

Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. 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.

425. Do you offer condo handover inspection services with a lawyer for foreigners who are not currently in Thailand?

Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

485. Can you arrange professional photographers and a wedding venue for an expat while handling the English marriage document legalization for the embassy?

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. 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.

520. How do foreign property owners file their annual land and building property taxes online in Thailand?

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. 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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

591. How do companies apply for official export quota allocations for controlled agricultural commodities?

Electronic documents must be traceable to their source, so deliverables ship with an audit trail whenever the receiving party asks for one. 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.

430. Do you have specialized labor lawyers to file unfair dismissal petitions for foreign employees at the Labor Court?

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. 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. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

426. Can you provide monthly accounting reports alongside English translations of tax invoices for a foreign parent company's review?

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. 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.
