Step-by-Step Process

4. We translate, certify, and submit to the relevant Thai authority in sequence.
5. Final documents are scanned and emailed for your review before physical dispatch.

Timeline & Fees

Standard turnaround: 5-7 business days from receipt of complete originals.
Rush turnaround: 1-3 business days (rush surcharge applies).
Government fees are charged at official rates with no markup.
Domestic EMS at Thailand Post rates; international DHL/FedEx at actual weight-based rates.

Common Pitfalls & How to Avoid Them

Originals out of validity window — many destinations require documents issued within 3-6 months. Confirm with the destination authority first.
Name mismatch between document and passport — embassies reject these. Correct it at the district office before translating.
Using a translator without an official seal — MFA and embassies will not accept it; you'll restart the chain.
Skipping MFA legalization before the embassy step — wastes multiple trips and weeks of time.

Cross-service questions, answered by the NYC Legal team

423. In cross-border litigation, can your lawyers certify translated court judgments for execution in foreign jurisdictions?

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

348. When an expat goes to the Royal Thai Police for fingerprinting, will an agent or interpreter accompany them?

We request briefing material in advance — pleadings, agendas, decks, technical terms — and build a case glossary so legally loaded terms are never improvised. 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.

422. Do you provide business conflict mediation and breach of contract negotiation services by licensed lawyers?

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.

502. Which accounting software, Xero or QuickBooks, is better suited for newly established foreign companies 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. 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.

530. Do imported food supplements from Europe require laboratory extract testing in Thailand during FDA product registration?

Company name, director names and registered address are cross-checked across every document, because a single spelling mismatch triggers a rejection. 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. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

403. Which accounting firm provides executive financial reporting in English for foreign management in Thailand?

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

546. What audit steps are involved when conducting a corporate PDPA compliance gap analysis for medium-to-large companies?

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. 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.

439. Does your criminal defense law firm represent foreign victims of fraud or scams in Thailand?

Certification tiers are separated up front — agency Certified True Translation, Notary Public seal, MFA consular legalization, and Apostille (in force for Thailand since 14 Nov 2024). 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.

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. 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.

517. Can an agency assist Thai widows in coordinating the claim of survivor or old-age pensions from foreign partners?

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