よくある質問
Q.タイの Notary と日本の公証役場の違いは?
タイの Notary Public は弁護士協会発行のライセンスを持つ弁護士が行う制度で、認証後に MFA + 大使館を経て海外で使用可能になります。日本のように公証役場が独立した制度ではないため、必ず MFA と大使館の追加認証が必要です。
Q.本人の出頭は必要ですか?
Notary 公証時は本人による対面署名が必要です(NYC は出張対応 / オンライン公証も可能)。来タイ困難な場合は海外ビデオ公証 + 国際郵送のプランをご案内します。
Q.料金体系は?
Notary 公証(500〜1,500 THB/署名)+ MFA 認証 + 大使館認証(実費)。事前に総額をご提示し追加請求はありません。
Q.委任状の海外有効期間は?
委任状の有効期限は作成者が文書内で指定(通常1〜3年)します。指定がない場合、海外受理機関は6ヶ月以内を有効とみなすケースが多く、期限切れの場合は再公証・再認証が必要です。
Cross-service questions, answered by the NYC Legal team
324. Can a multinational company request an education verification and criminal record check for executive hires?
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. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Tell us where the document will be used and you will get a plan and a price the same business day. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. Fix three facts before any work starts: the destination country, the exact authority the file goes to, and the language that authority requires. Those three decide the whole certification chain. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
401. Where to find monthly bookkeeping and annual financial statement closing services for foreign companies using Xero in Thailand?
Every certified file passes three hands: a native-speaking translator, a subject-matter reviewer, and the responsible attorney who signs the certification page. Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing.

287. Do you offer a package for drafting a bilingual commercial contract combined with legal translation?
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. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Tell us where the document will be used and you will get a plan and a price the same business day. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first.

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

316. How do I subscribe to a 24/7 Over-the-Phone Interpreting (OPI) service for resolving urgent expat issues?
For proceedings that go on the record we staff paired interpreters rotating every 20–30 minutes, per international conference practice. 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. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing.

356. Can an agency manage the bank deposits and health insurance requirements for a foreigner's O-A/O-X retirement visa?
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. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

443. If a foreign company lacks an HR department, can your agency handle payroll, expat visa renewals, and P.N.D.1 tax filings entirely?
Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. Processing time depends on each authority's queue, so the working order and the expected return date are confirmed before any work begins. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected.

Can an authorised representative handle a concierge document programme with a dedicated coordinator on the client's behalf?
The jobs others decline — rare languages, low-traffic embassies, hard-to-read archival documents — are assessed case by case with an honest feasibility answer. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote.

Before you start: Guidance and cautions
Practical guidance
- Confirm the receiving authority and destination country first — translator qualification and certification layers are dictated by the destination, not by the document type.
- Scan every page of the original, including stamped pages, signature pages and reverse sides that look blank.
- Spell every name in the translation exactly as it appears in the passport, including titles and middle-name order.
- Ask about current processing windows before booking flights or an appointment abroad — authority queues shift through the year.
Cautions & common rejections
- A name that does not match the passport is the single most common rejection reason, and usually forces the whole certification chain to restart.
- Government fees and turnaround times change. Re-check them with the issuing authority close to your submission date.
- Submitting a photocopy where an original or certified extract is required gets refused at the very next certification layer.
- Many Thai civil-registry extracts are accepted only while recent; some receiving authorities ask for a freshly certified copy. Confirm the accepted age with that authority before ordering a translation.
What to have ready
- The name of the receiving authority and destination country
- A valid passport or Thai ID of the document holder
- The original document or a certified extract from the issuing authority
- Your deadline, so the certification steps can be sequenced in time
