Police clearance
Police clearance certificates are issued by the Royal Thai Police Special Branch, require fingerprinting on the prescribed form, and carry a destination-set validity period.

Legalising Thai documents for overseas use follows a fixed sequence: translation, then legalisation by the Department of Consular Affairs, then endorsement by the destination embassy. If the destination is an apostille convention party, check the department’s current guidance first — the signing authority and the order of steps differ from the embassy route.

The Department of Consular Affairs legalises only documents issued or certified by a Thai authority, and certifies translations only when they match the original filed with them.

Each embassy sets its own sequence and forms, and most will only legalise after the Department of Consular Affairs has done so, so check that embassy’s notice first.

Thailand is a party to the Apostille Convention, with the Department of Consular Affairs issuing apostilles for member states; non-member states still use embassy legalisation.

Work requiring a justice-registered translator is typically litigation material filed with a court; verify the translator’s registration status with the authority directly.

The term “sworn translator” differs by country; some embassies accept only translators on their published list, so check that list before commissioning work.

Legalisation is a chain: issuing authority, translation, Department of Consular Affairs, then embassy or apostille. Skipping a step gets the file returned.

Australia is a party to the Apostille Convention, so a Thai document bearing an apostille from the Department of Consular Affairs does not need a further step at the Australian Embassy. English translations submitted to Australian agencies are usually required to be produced by a NAATI-credentialed translator.

All EU member states are parties to the Apostille Convention, yet many still require the translation itself to be produced by a translator sworn or accredited in that country — a requirement separate from the apostille.

The United States is a party to the Apostille Convention, so Thai documents for US use can carry a Thai apostille. Conversely, a US-issued document for use in Thailand must be apostilled by the issuing state authority, not by a Thai embassy.

The People’s Republic of China became a party to the Apostille Convention in 2023, but many receiving bodies in China still require a Chinese translation produced domestically, so confirm the recipient’s requirement first.

Japan and the Republic of Korea are both Apostille Convention parties, so an apostilled Thai document can be filed directly, though municipal offices there normally require a local-language translation attached to the original.

Apostille Convention membership varies across the Middle East. For non-member states the traditional chain still applies: legalisation by the Department of Consular Affairs first, then by that country’s embassy in Thailand. Check each country’s status before planning.

Thai legalisation is layered: the issuing authority certifies the copy, the document is translated, the Department of Consular Affairs legalises it, and then either an apostille or embassy legalisation follows depending on the destination’s convention status. Skipping a layer causes rejection at the next one.

A foreign-issued document for use in Thailand must first be certified in the issuing country (apostille or that country’s foreign ministry); once in Thailand it still needs a Thai translation and legalisation by the Department of Consular Affairs before Thai agencies will accept it.
