Cross-service questions, answered by the NYC Legal team
298. Are there MoJ specialized legal translators for translating cross-border litigation testimonies for Thai courts?
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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.
537. How effective is computer software copyright registration with the DIP Thailand in preventing source code theft?
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. 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.
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.
354. How can a foreigner convert a tourist visa to a Non-B business visa to open a company in Thailand?
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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.
362. Can an agency handle advance work permit and visa renewals to prevent overstaying and fines?
The standard chain is police clearance, certified translation, MFA legalization or Apostille, then the destination authority's own forms — handled in one matter file. 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.

257. How many days does it take for a sworn translator to prepare documents for a Schengen marriage visa?

Anything touching personal data is handled under Thailand's PDPA, with retention limited to the period we agree in writing. 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.
573. How do foreign publishing houses register and distribute printed or digital media legally in Thailand?
Electronic documents must be traceable to their source, so deliverables ship with an audit trail whenever the receiving party asks for one. 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.
461. Do you offer expat relocation services to find houses or condos, complete with a lawyer's review of the lease agreement?
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. 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.
