日本のお客様向け詳細 FAQ
在タイ日本人・日系企業のお客様が公証手続きで実際によく遭遇する具体的な疑問点(大使館領事認証、戸籍謄本、相続、不動産売却委任状)に詳しくお答えします。
在タイ日本国大使館の領事認証はどのくらい時間がかかりますか?
在タイ日本国大使館 (バンコク、Wireless Road) の領事認証は、原則として申請後 2 営業日後に交付されます。事前予約は不要ですが、申請受付時間は平日 8:30〜11:30 のみ (午後は受付不可)。窓口で本人または代理人が申請書 + Notary 認証済み文書 + MFA 認証済み文書一式を提出します。当社では Notary + タイ外務省 (MFA) + 日本大使館の 3 段階を完全代行可能で、お客様は来店不要、通常 7〜10 営業日で全工程完了し EMS で日本へ発送します。
日本の戸籍謄本を取り寄せてタイで公証することは可能ですか?
可能です。日本のご家族または委任した司法書士に取得を依頼し、原本を国際 EMS で当社に送付してください。当社にて ① 日泰翻訳 (登録翻訳士) ② 公証人による翻訳認証 ③ タイ外務省 (MFA) 認証 ④ (必要時) 在タイ日本大使館の領事認証、を一括で行います。タイの婚姻登録、配偶者ビザ申請、不動産取引等で頻繁に使用されます。発行から 3 ヶ月以内の戸籍謄本が要求されるケースが多いので、取り寄せのタイミングにご注意ください。
日本にある不動産の売却・相続のためにタイで委任状 (POA) を作成できますか?
できます。日本の不動産売買、相続登記、預貯金解約等のための委任状は、日本の法務省・法務局の要求する形式 (在外公館用委任状) に準じて作成し、Notary + MFA + 在タイ日本大使館の 3 段階認証を経ることで、日本の登記官・銀行・税務署で有効になります。当社では日本の司法書士・弁護士からのドラフトをお預かりし、公証人面前での署名 → 認証 → 国際郵送までを一括代行。相続案件で兄弟姉妹が複数国に居住している場合の同時手続きも対応可。
在タイ日本商工会議所 (JCC) メンバー企業向けに特別サービスはありますか?
はい。当社は在タイ日本企業向けに年間 800 件以上の公証実績があり、JCC メンバー企業様には:① 専任日本語アカウントマネージャーの配置 ② 法人税務インボイス即日発行 ③ 工場・本社へのオンサイト出張公証 (バンコク、アユタヤ、チョンブリ、ラヨーン、シラチャ) ④ 急ぎの取締役会決議・株主総会議事録の翌日 MFA 認証 ⑤ 駐在員のパスポート謄本認証の月次まとめサービス、を提供。詳細はお問い合わせ時に“JCC 会員”とお伝えください。
ハーグ条約に基づくアポスティーユ (Apostille) でも対応可能ですか?
対応可能です。ただしタイは現時点 (2026 年) でハーグ条約 (アポスティーユ条約) に未加盟のため、タイ発行文書については Apostille は付与できず、従来の領事認証 (Legalization) ルートとなります。一方、日本発行文書 (戸籍謄本、卒業証明書等) でタイ国内使用のために Apostille が必要な場合は、日本の外務省で Apostille を取得した上で当社にて日泰翻訳と公証認証を行います。日本がハーグ加盟国であるため、相手国がハーグ加盟国であれば Apostille のみで完結します。
在留邦人の死亡時、相続手続きで必要な公証はどう進めますか?
在留邦人の死亡時、相続関係手続きで必要となるタイ国内の財産 (銀行預金、不動産、車両等) の名義変更には:① タイの病院発行の死亡診断書 → 翻訳 + 公証 + MFA + 日本大使館認証 ② タイの Amphoe で発行される死亡証明書 (Mor Tor 14) → 同上 ③ 相続人代表の身分証明 + 委任状 → 在日本の公証役場 + 外務省 Apostille (日本側) → タイで再認証、が必要です。当社は遺族の方の心理的負担を軽減するため、葬儀社・大使館・銀行・弁護士との橋渡しまで含めたパッケージ対応をしています。
ロングステイビザ (Non-O リタイアメント) 更新時に公証は必要ですか?
Non-O リタイアメントビザ (50 歳以上) の更新時、年金証明書または銀行残高証明書 (タイ国内銀行 80 万バーツ以上) を提出します。日本から年金証明書を取り寄せる場合、年金事務所発行の証明書 → 日本外務省 Apostille → タイ語翻訳 + 公証 → イミグレーション提出、の流れになります。日本大使館での領事認証ルートも可能ですが、Apostille の方が迅速 (約 1 週間短縮) です。配偶者ビザ (タイ人配偶者) の場合、戸籍謄本翻訳公証も追加で必要となります。
日本の運転免許証をタイで翻訳・公証して国際的に使うことは可能ですか?
可能です。日本の運転免許証を当社にて ① 日英 + 日泰翻訳 ② 公証人による翻訳認証、を行うことで、タイ国内での運転免許切替申請、長期滞在国 (シンガポール、マレーシア、UAE 等) での運転免許取り直し、レンタカー利用等に使用できます。注意:タイ国内での短期運転には日本発行の国際運転免許証 (ジュネーブ条約) が必要で、翻訳公証だけでは不可。タイ免許への切替には、当社翻訳公証 + パスポート + 居住証明 (Certificate of Residence) で陸運局申請が可能です。

Cross-service questions, answered by the NYC Legal team
353. What chat evidence and legal documents are required for a fiancé visa or settlement marriage visa application?
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. 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. 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: 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. 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.
375. Does your agency offer a complete package: BOI application, company registration, Non-B visas, and work permits for foreign experts?
Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. 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. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. 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.
Which authority is responsible for assembling a document pack ahead of a biometrics appointment, and where can it be filed?
Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. 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. 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. 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: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
473. Do you provide financial background checks on expats to give luxury property landlords peace of mind?
Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. 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. 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: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. 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. 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.
Can an authorised representative carry out preparing tax and legal records for a foreign authority on someone's behalf?
Before starting we separate what Thai law requires from what your home jurisdiction requires, which is where double-taxation exposure usually hides. 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. 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. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. 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: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. 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. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
How long does the full process for certified documents for an infrastructure tender usually take end to end?
Where a project has counterparties in several countries, we deliver every language version the contract names as governing. 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. 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. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
Does certified documents for a Mekong-region market entry require a certified translation to be attached?
Space, satellite, quantum and holding-structure work uses terminology that is still settling, so we agree a glossary with your advisers before drafting begins. 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. 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: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it.

Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
408. Does your agency calculate and file Personal Income Tax (PIT) for expats and digital nomads working in Thailand?
Cross-border wills and estates must be read against the destination jurisdiction, and we coordinate local counsel where that is required. 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. 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: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. 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.
445. Do you offer Indian PAN card application services for Thai individuals wanting to invest in Indian mutual funds?
M&A and fundraising work demands speed and confidentiality, so we sign the NDA before intake and ring-fence a closed team for the matter. 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. 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. 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.

Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
498. Do you offer a door-to-door service to get a Certificate of Single Status, notarize it, and DHL it to Australia?
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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. 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. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it.

Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
Which documents must be prepared for a guardianship document set for an overseas school?
We provide an interpreter and an escort on the day itself, because the counter stage is where most applicants lose a trip. 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. Tell us where the document will be used and you will get a plan and a price the same business day. 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: 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.

Does a full family relocation document package require a certified translation to be attached?
We provide an interpreter and an escort on the day itself, because the counter stage is where most applicants lose a trip. 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage.

Full service playbook — Notarial Services Attorney (Thailand)
Thailand has no common-law Notary Public. The equivalent is a Notarial Services Attorney, a lawyer certified and registered by the Lawyers Council of Thailand, whose certificates are accepted by most overseas authorities.
Responsible authority: Notarial Services Attorney registered with the Lawyers Council of Thailand
Documents to prepare
- Original passport or Thai ID of every signatory (shown in person)
- The original document to be certified, all pages included
- The photocopy to be certified, if you need a certified true copy
- Any destination-specific form or power of attorney template
- Company affidavit issued within 6 months plus director ID, for corporate files
- An English translation where the source document is in Thai
Step-by-step process
- 1. Classify the certificate requiredsame day
Decide between signature witnessing, certified true copy, affidavit/oath, or certification of translation — the wording differs for each.
- 2. Attend and sign before the attorney15–30 minutes
Signatories sign in person with original ID; corporate files need the director named on the company affidavit.
- 3. Attorney signs, seals and logs the registersame day
A certificate is attached to the document and entered in the register kept under Lawyers Council rules.
- 4. Proofread before use1 business day
Verify names, dates, page count and binding against the destination's instructions.
- 5. Escalate to MFA or embassy if required3–10 business days
If the destination expects consular legalisation, forward immediately so the file does not age out.
Practitioner tips
- Ask the destination whether a Thai Notarial Services Attorney is accepted directly or must be followed by MFA legalisation.
- Certify multiple documents in one sitting to keep register numbers sequential and traceable.
- Match the Latin spelling of your name to your passport exactly — receiving authorities compare character by character.
- Confirm whether the destination wants an original or a certified copy — the two follow different routes.
- Scan every page to 300 dpi colour PDF before the originals leave your hands, in case a re-submission is required.
Cautions
- An attorney cannot certify a signature that was not made in their presence.
- Certification confirms the signature or the copy, not the truth of the content.
- Do not write on, amend, or correction-fluid an official document; request a fresh copy from the issuing office instead.
- Unsigned translations cannot be certified — the certifying office will refuse to stamp them.
- Never unstaple or re-bind a certified bundle — breaking the seal usually voids it and restarts the process.
DIY vs NYC handling it
| Task | Do it yourself | NYC handles it |
|---|---|---|
| Checking destination rules | You read checklists and call around yourself | We verify the current requirements and hand you one list |
| Multi-agency running | Several days off work, different queues and hours | We run the whole chain end to end for you |
| Translation and certification | You source a translator and risk rejection | Translated, double-checked and certified in one package |
| Errors and re-filing | One mistake restarts the whole chain | Pre-submission checks at every stage reduce rejections |
| Tracking | You chase the status by phone | Stage-by-stage updates on LINE with photo evidence |
Prefer not to run it yourself? NYC can handle the whole chain
Every step above can be done alone, but it means several agencies, mismatched queues, and one mistake restarting the sequence. Our attorneys and translators cover requirement checks, document re-issue, certified translation and MFA or embassy legalisation, with status updates at each stage. Send photos of your documents for a free assessment first.
Compare the options before you decide
Thailand's notarial attorney vs a foreign Notary Public
Thailand has no Notary Public office in the international sense. Equivalent work is performed by a Notarial Services Attorney licensed by the Lawyers Council of Thailand.
| Aspect | Thailand: notarial attorney | Abroad: Notary Public |
|---|---|---|
| Who is authorised | An attorney licensed for notarial services by the Lawyers Council | A notary appointed by the state or a court |
| Scope | Signature certification, true copies, affidavits and translations where the law allows | Varies by jurisdiction |
| Usual next step | File with the Department of Consular Affairs, then Apostille or embassy | Usually the country's own central authority |
| In-person required | Yes — you sign in front of the certifying attorney | Generally yes |
Where the receiving body uses its own terminology, follow that wording rather than claiming an equivalent title.
Apostille route vs embassy legalisation route
The destination country decides whether a file ends at an Apostille or still needs the embassy. Confirm the country's convention status first: the two routes use a different order and different paperwork.
| Aspect | Apostille route | Embassy legalisation route |
|---|---|---|
| When it applies | Destination is a party to the Apostille Convention | Destination does not accept an Apostille |
| Final authority | Department of Consular Affairs, Ministry of Foreign Affairs | The destination country's embassy or consulate in Thailand |
| Typical number of steps | Fewer — the chain ends at the central authority | More — central authority first, then the embassy |
| Approximate timeframe | Shorter, still subject to the authority's queue | Longer, because the embassy appointment queue is added |
| Common rejection cause | Translation does not match the original, or the copy was not issued by the authority | The embassy's own form or language requirement was not followed |

Filing it yourself vs letting NYC run the chain
Every step can be done alone. This table compares the real workload of each option so the decision rests on time and rejection risk rather than marketing claims.
| Aspect | Do it yourself | NYC handles it |
|---|---|---|
| Checking destination rules | Read each authority's notice yourself and confirm by phone | Checked before you start, with the order the receiving authority accepts |
| Travel | Several agencies with queues that rarely line up in one day | Documents move by courier or online except where the law requires you in person |
| Rejection risk | One mismatch — a name spelled differently from the passport — restarts the chain | Names, dates and stamps are cross-checked before every filing |
| Status tracking | You follow up with each authority | Status updates at each stage, and we handle the fix if a file is returned |
| Advisory role | No one to compare options when your case falls outside the manual | You get advice on the options before work starts, not just execution |
Government fees and timeframes change; ask for an assessment of your own case before you start.
What the common mistakes actually cost
Almost every failure in notarial signature certification by a licensed attorney happens during preparation, not at the counter, and the real cost is the TIME needed to repeat the chain. Below is what each mistake comes from, how long it typically adds, and how to avoid it.
| Mistake | Why it happens | Time cost | How to prevent it |
|---|---|---|---|
| Self-translating, or using a translator the destination does not recognise | Some countries accept only registered translators, others only translations certified by a Thai government body. | Typically adds 4–10 working days for a fresh translation and a restarted chain. | Ask the destination exactly which form of translation it accepts, then match the translator to that form from the start. |
| Removing staples or separating pages after certification | The certification is attached to the bound set; once separated the set counts as incomplete. | Typically adds 3–7 working days to re-certify the set. | Scan first, then keep the originals in a rigid envelope without detaching anything. |
| Planning without allowing for public and embassy holidays | Embassies close on both Thai and home-country holidays, so the real calendar is shorter than it looks. | Typically adds 3–9 working days around a long holiday period. | Check the holiday calendar of every body involved before fixing a travel or filing date. |
| Using an old copy instead of a freshly issued one | Many destinations accept documents issued within the last 3–6 months only, and some require a clean, legibly sealed reissue. | Typically adds 5–15 working days for the trip back to the district registrar. | Check the destination's freshness rule first, then request several certified copies in a single visit. |
| Running the chain in the wrong order — embassy before the consular department | Each body only certifies the signature of the body immediately before it in the chain. | Typically adds 5–12 working days and forces a re-filing from the skipped stage. | Confirm the route with the receiving authority before starting, or have us map the chain up front. |
Deep timeline: what can run in parallel
The windows below are approximate and depend on each authority's queue. Stages marked as parallel can start alongside the previous stage — that is where the total calendar time is actually reduced.
- 1. Document review and certificate wordingsame day
We confirm whether you need a signature certification, a true-copy certification, or a statement of fact — each uses different wording.
- 2. Signing appointment in person1–2 working days
The signatory must appear with an original ID or passport at the moment of signing.
- 3. Certificate issued and sealedsame day
The certificate is issued with a register number and logged under Lawyers Council rules.
- 4. Onward legalisation, if the destination requires it3–10 working dayscan run in parallel
For overseas use the file may still pass the consular department and then the embassy, in that order.
Note: all windows are general estimates, not guarantees. Actual timing depends on how complete your file is and on the queues at the authorities involved.
We work as advisers, not only as a document-running agency
Our team has worked on documents, translation and legalisation for more than 15 years, combining notarial attorneys licensed by the Lawyers Council of Thailand with translators the receiving authorities accept. Every case starts with advice on the correct route and only then moves to execution — we do not simply run whatever is handed to us.
Before we start — mapping the document route
We confirm whether your file ends at an Apostille or still needs the embassy, whether a freshly issued copy is required, and which form of translation the receiving authority accepts. This is where most time is saved, because it is where most people choose wrongly and restart.
While preparing — consistency checks
We match the spelling of your name against the passport, check the issue date against the validity window the destination applies, verify stamps and signatures, and confirm the translation matches the original line by line.
While filing — coordination with the authorities
We file in the order each authority expects, follow the queue, and report status as it moves. If an authority asks for more paperwork, you hear about it immediately, together with the options for fixing it.
After delivery — practical guidance
We explain which bodies this set can be filed with, how to store the originals, and how many certified sets to request up front if you expect to use them again, so you do not repeat the whole chain later.
Cases where advice up front changes the outcome
- Documents have a limited validity window and every item must still be valid on the day of filing.
- The applicant is upcountry or abroad, so the power of attorney and courier plan must be arranged carefully.
- Documents are needed for several countries at once, each with a different order of certification.
- The destination only says "certified translation" without stating which form of certification it accepts.
If you are unsure which route your case takes, send photos of the documents and name the destination country or authority. We map the sequence and the paperwork first; you then decide whether to run it yourself or hand it over.
