タイ駐在の方、タイ人配偶者をお持ちの方、日本の不動産・相続・銀行手続きをタイから進めたい方に。
最初に確認すること：提出先はどこか
日本の法務局、銀行、家庭裁判所などは、それぞれ求める書式が異なります。在タイ日本国大使館での署名証明を求める機関も多くあります。提出先の案内や書式をお持ちいただき、どの方法が適切か一緒に確認します。
- 委任状・宣誓書の署名認証
- 原本と写しの相違ない旨の認証
- 日タイ・英タイ翻訳と翻訳者証明
- 会社書類（登記証明・株主名簿の写し）
大使館の署名証明との違い
日本の手続きでは、在タイ日本国大使館が発行する「署名証明（サイン証明）」や「在留証明」で足りる場合が多く、その場合はタイの弁護士認証は不要です。一方、タイ側の機関や第三国向けの書類では弁護士認証が求められることがあります。大使館の最新案内は公式サイトでご確認ください。
アポスティーユについて
日本はアポスティーユ条約加盟国ですが、タイの状況はタイ外務省領事局の最新発表で確認する必要があります。現時点では、タイ書類は「領事局認証 → 提出国大使館認証」の流れが一般的です。
手続きの流れ
- 要件の確認提出先の書式や案内をご提示いただき、必要な手順を確認します。

Frequently asked questions
- Does Thailand have notaries public?
- Thailand uses Notarial Services Attorneys registered with the Lawyers Council of Thailand for notarial acts within their permitted scope. Acceptance abroad depends on the recipient. Ask which certifier, wording and any additional authentication it requires; notarial certification is not the same as an Apostille.
- What documents can a Notarial Services Attorney certify?
- Commonly certified items include signatures on powers of attorney, affidavits and statutory declarations, certified true copies of passports and corporate documents, company resolutions and share transfer forms, sponsorship and consent letters, and the identity of a signatory for foreign banks, universities and courts. The attorney certifies the signing act or copy fidelity — not the truth of the content.
- Do I have to sign in person?
- Yes. The attorney must see the signatory in person together with the original passport or Thai ID before certifying a signature, which is the core safeguard of the service. Remote or scanned signatures cannot be certified. Mobile appointments at your office, condominium lobby or a nearby café are available if you cannot come to ours.
- How much does notarial certification cost and how fast is it?
- Attorney notarial certification starts at the current official rate per document, with the final price depending on the number of documents, signatories and whether the appointment is mobile or out of hours. The certification itself is completed during the appointment; only the subsequent MFA and embassy steps add working days.
