Notarised Parental Consent for a Child to Travel — Thailand (2026)

Needed when a child travels with one parent, with relatives or unaccompanied. Airlines and immigration authorities frequently require a witnessed consent letter, which is also used to support minors' student visa applications.

The child's birth certificate and house registration showing the relationship · Passports or ID cards of both parents · If divorced, the divorce agreement or court order confirming custody · Travel details: destination, dates and the accompanying guardian

Witnessing the parent's signature and administering the declaration

Only one parent signs without evidence of sole custody · Omitting travel dates and destination, which airlines reject · The child's name spelled differently from the passport

For embassy or government use, follow with MFA legalisation and destination embassy attestation.

Same day; book ahead when both parents must attend together. 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.
