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

419. Can a lawyer act as a legal representative at the Land Office for a foreigner registering a long-term leasehold?

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

385. Can a foreigner holding a DTV visa open a company in Thailand, or do they need to change their visa type?

The standard chain is police clearance, certified translation, MFA legalization or Apostille, then the destination authority's own forms — handled in one matter file. 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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

273. Can an MoJ certified translator authenticate an arrest warrant or court summons for foreign execution?

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.

583. How do companies secure approval for corporate employee housing compounds and residential dormitories?

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

Tell us where the document will be used and you will get a plan and a price the same business day.

508. What are the benefits of subscribing to an Annual Expat Concierge membership for managing visas and government paperwork?

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.

Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

287. Do you offer a package for drafting a bilingual commercial contract combined with legal translation?

Every certified file passes three hands: a native-speaking translator, a subject-matter reviewer, and the responsible attorney who signs the certification page. 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.
