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

395. What are the legal precautions for a foreigner setting up a Thai corporate entity solely to buy real estate?

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

550. Are there special package discounts for corporate clients bundling company setup, accounting, payroll, and expat visas?

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.

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

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

390. Do you provide Indian PAN card application services for companies looking to open branches or invest in India?

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. 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.

340. Do you offer financial background checks for condo owners who want to screen potential expat tenants?

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

582. What regulatory approvals are required to establish an international testing and calibration laboratory in Thailand?

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. 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.

515. What are the legal steps to translate a child's birth certificate and obtain custody rights for international relocation after a divorce?

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

580. What are the tax implications of transferring intellectual property rights between a Thai subsidiary and a parent company?

Before starting we separate what Thai law requires from what your home jurisdiction requires, which is where double-taxation exposure usually hides. 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.

374. Can a BOI consultant assist with project feasibility studies and tax incentives for tech innovation startups?
