MFA legalisation in Thailand — questions clients actually ask

Answers on document legalisation at the Department of Consular Affairs — civil-registry records, education and company documents, translation legalisation and onward embassy attestation. (35+ search topics covered)

What must a foreign document pass before Thai legalisation?

It generally must be authenticated by the competent authority in the issuing country, then certified by the Thai embassy or consulate there, or by that country's embassy in Thailand, before being filed with a Thai translation. The sequence cannot be reordered.

What causes most rejections?

Uncertified photocopies, translations that deviate from the original or use a spelling other than the passport spelling, documents outside the destination's validity window, and obsolete form versions.

How long do legalised documents stay valid?

The stamp has no expiry, but receiving authorities frequently require the underlying certificate — single status, company affidavit, police clearance — to have been issued within three to six months of submission.

Does Thailand issue Apostilles?

Thailand deposited its instrument of accession to the 1961 Apostille Convention on 30 June 2026, and the Convention enters into force for Thailand on 28 February 2027. Until that date Thai documents still follow the two-step route: legalisation by the Department of Consular Affairs, then legalisation by the destination country's embassy in Thailand.

Is there an express service?

The Department operates standard and express channels with different cut-off times and fees. Confirm the current schedule on the Department of Consular Affairs website before booking a visa appointment.

Which version of the document must be submitted?

The original, or a copy certified with the seal of the issuing authority: a district office for civil-registry records, the institution for education documents, and the Department of Business Development registrar for company documents.

Will Thailand's accession to the Apostille Convention remove the embassy step?

For destinations that are parties to the Convention, an apostille will replace the embassy legalisation step once the Convention enters into force for Thailand on 28 February 2027. Until that date, Thai documents still require certification by the Department of Consular Affairs followed by the destination country's embassy in Bangkok. Non-party destinations will continue to use the embassy route afterwards.

Which documents are accepted as originals for legalisation?

Generally documents issued by a Thai government office bearing an original signature and seal, or certified true copies issued by that office. Plain photocopies, scans and reprints are typically refused. Where the original must be retained, the issuing office can usually provide an additional certified copy, which is the safer route than submitting a copy certified by a third party.

Practical Q&A

Practical questions · Near me / DIY / Required documents

Where is document legalisation done in Thailand?

Legalisation is handled by the Legalization Division, Department of Consular Affairs, Ministry of Foreign Affairs, whose main office is on Chaeng Watthana Road, plus selected regional passport offices that accept legalisation under the department's announcements. If travelling there is inconvenient, we collect and submit on your behalf from Lat Phrao 95, Khon Kaen and Udon Thani.

Can I submit it myself instead of using an agent?

Yes. The Department of Consular Affairs accepts walk-in and online-booked submissions from the public. The practical risk is sequence and format: official documents must be the issuing authority's version, then translated and certified in the correct order, or they are returned. An agent mainly saves repeat trips and pre-checks the format.

What do I need to bring for legalisation?

Typically the original document issued by the competent authority, a complete and accurate translation, a copy of the document owner's ID or passport, and a power of attorney with the representative's ID copy if someone submits for you. Foreign-issued documents must first be authenticated in the country of origin and by the relevant embassy.
Practical advice & cautions

Legalization & apostille: practical advice and cautions

Before you start

  • Get the receiving party's requirements in writing

    Universities, employers and registry offices publish their own checklists. Obtaining that checklist first fixes the number of copies, the language and the certification route correctly on the first attempt.

  • Prepare translations in the format the certifying office actually uses

    The Department of Consular Affairs certifies translations presented in its expected format. Self-formatted translations are frequently sent back for correction, costing a full queue cycle.

  • Check whether the destination is an Apostille Convention party

    For member states the chain ends with an apostille and no embassy step is needed. For non-member states the document must continue through the destination country's embassy. Verify the current member list on the HCCH website.

  • Keep a scanned backup at every stage

    Photograph or scan every page before submission and again after each stamp, so you have a reference if a document is lost in transit.

Common reasons documents get rejected

  • Mixing both routes

    Requesting an apostille and an embassy legalization at the same time when only one is required wastes time and can raise questions at the destination. Pick the single route that matches the destination's convention status.

  • Certifying a copy that no longer matches the register

    If a registry entry changes after the copy was issued, for example a name change or address move, the certified copy will contradict the database. Re-issue before starting.

  • Signature mismatch

    Signature attestation is compared against the signature on the ID card or passport. A different signature style will be refused at the counter.

  • Opening a bound and sealed bundle

    Bundles sealed across the binding must never be separated. Removing the staple voids the certification and the whole set has to be redone.

Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
