よくある質問
Q.MFA 認証と大使館認証の違いは?
MFA = タイ側公文書の真正性を保証 / 大使館 = MFA の認証を目的国側が認める。多くの国で両方必須。
Q.翻訳なしで MFA だけ取れますか?
可能。英文原本がそのまま受理される目的国 (米国の一部州など) は「公印認証のみ」で OK。日本提出は基本的に日本語翻訳必須。
Q.アポスティーユは使えますか?
タイは 2024年12月31日にハーグ条約加盟、2025年1月1日からアポスティーユ発給開始。日本もハーグ加盟国のため、領事認証の代わりにアポスティーユで簡略化可能。
Q.MFA 加急の費用は?
官費 400 バーツ/通 (標準 200 バーツ)、代行費別途。加急パッケージ (翻訳+MFA+受取) で 2,500〜4,500 バーツ/通。
Q.リモートで委任できますか?
可能。当社バンコクオフィスへ原本郵送 → MFA・大使館手続き → DHL で返送。タイ渡航不要。
Q.MFA 認証後に翻訳の修正はできますか?
不可。MFA 押印後は確定。修正には再翻訳 + 再認証 (再課金) が必要です。
Q.認証の有効期限は?
MFA 認証自体は無期限ですが、目的国側で「6か月以内発行」を要求されることが多い。使用予定の 60〜90 日前の取得を推奨。
Cross-service questions, answered by the NYC Legal team
274. How to get an Apostille stamp from the Thai MFA for corporate documents to open a branch in South Korea?
Every certified file passes three hands: a native-speaking translator, a subject-matter reviewer, and the responsible attorney who signs the certification page. 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. 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: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. 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: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
Which authority is responsible for arranging an interpreter for a cross-border business meeting, and where can it be filed?
Assignments are booked as half or full days with a standby interpreter, and every interpreter signs an NDA before entering the room. 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. 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: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. 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: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification.

442. Is there a package for a notary lawyer to authenticate land purchase signatures and act as an interpreter at the Land Office?
Interpreters are matched to the setting: court and police station, government and embassy, medical, simultaneous booth work, and remote VRI/OPI. Processing time depends on each authority's queue, so the working order and the expected return date are confirmed before any work begins. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. 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: 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. 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.

339. Can you provide a team of simultaneous interpreters for 3 languages (Thai, Chinese, English) at an international trade show?
For proceedings that go on the record we staff paired interpreters rotating every 20–30 minutes, per international conference practice. 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage.

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: 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.

Which official fees should be budgeted in advance for an interpreter booked alongside certified documents for a business negotiation?

470. Does your agency offer online e-Visa application assistance for Australia and New Zealand for clients unfamiliar with the system?
Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. 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.

Which office must be approached first for certified documents for frontier markets in the Mekong region, and with which documents?

579. How do foreign franchise brands protect their trade secrets and proprietary recipes under Thai IP law?
Company name, director names and registered address are cross-checked across every document, because a single spelling mismatch triggers a rejection.

Before you start: MFA legalisation & embassy attestation
Practical guidance
- Scan every page of the original, including stamped pages, signature pages and reverse sides that look blank.
- Budget queue time at both the Department of Consular Affairs and the embassy, especially around either country's public holidays.
- Sequence the chain before you start: issuing agency → translation → Department of Consular Affairs → destination embassy where required.
- Confirm with the destination embassy which translation language it accepts; several accept only their own official language.
Cautions & common rejections
- Submitting a photocopy where an original or certified extract is required gets refused at the very next certification layer.
- Foreign-issued documents must be certified in their country of origin first; only then can they be translated into Thai and legalised here.
- Government fees and turnaround times change. Re-check them with the issuing authority close to your submission date.
- 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
- A copy of the holder's passport or Thai ID
- Your deadline, so the certification steps can be sequenced in time
- The original document or a certified extract from the issuing authority
- A translation matching the original page for page
