Notarised Passport Copy for Overseas KYC — Thailand (2026)

Required to open overseas bank or brokerage accounts (Wise, Interactive Brokers, Singapore and Hong Kong banks) and to verify shareholders or directors of foreign companies.

A valid, unexpired original passport · The bank's own certification form if it prescribes specific wording · Proof of address (utility bill or house registration) when the bank also requires it

True-copy certification together with identity verification against the passport photo

Using an old certificate when the bank requires one issued within the last three months · Omitting the certifier's name, licence number and office address that KYC teams require · Certifying only the biodata page when the bank also wants the signature and entry-stamp pages

A colour scan is usually accepted immediately, with the hard copy couriered if the bank asks for it.

Same day, with a scanned copy sent ahead of the originals. Fees are based on the number of documents and stamps, and you get a written quote before any work starts.

No. Thailand is not a party to the Hague Apostille Convention, so Thai documents intended for use abroad follow the legalisation route: certification by a notarial services attorney, then legalisation at the Department of Consular Affairs (Ministry of Foreign Affairs), then attestation at the destination country's embassy or consulate in Thailand. Check the current status with the HCCH and the Department of Consular Affairs before you act.

Thailand has no notary public office in the common-law sense. Instead, lawyers registered with the Lawyers Council of Thailand under its 2008 regulation act as Notarial Services Attorneys, and their certifications are the form accepted by foreign authorities.

Yes for signature certification — you sign in the attorney's presence with an original passport or Thai ID. For a certified true copy, the original document must be produced.
