The birth certificate is issued by District registrar (amphoe) or Bangkok district office. A registrar-certified copy is required, not an ordinary photocopy. It is then translated to the standard Finland accepts, legalised at Consular Affairs and attested at the destination mission where the receiving body requires it.

Anyone submitting a birth certificate in support of a visa application, a civil-status registration, an employment file, or a court or registry filing in Finland is normally required to submit both the Thai original issued by District registrar (amphoe) or Bangkok district office and a properly certified translation. Filing only the translation is one of the most common reasons a file is returned unread.
Foreign nationals sending a birth certificate back for use in Finland — to prove family status, claim an inheritance, apply for a benefit or confirm an address — should first confirm whether the receiving body requires legalisation by the Department of Consular Affairs, and whether the Finland mission in Thailand must attest the document afterwards.
Employers posting staff to Finland, or filing contract and registration documents, should prepare the whole bundle as a single set so that personal names, company names and spellings match on every page. A one-letter discrepancy between passport and certificate routinely forces the entire certification chain to be restarted.
Before starting the certification chain for Finland, gather the following in one pass. Doing so keeps the file to a single round and avoids having to re-issue documents later.
Each certification answers a different question, and choosing the wrong one costs a full round trip. For a birth certificate intended for Finland, the differences are as follows.

The Finnish population register checks name continuity closely; if a name or surname has ever changed, evidence of every change should be prepared at the same time
In practice, confirm the required format with the receiving authority in writing before starting: two bodies in the same country often differ. Some accept a translation certified in Thailand, while others insist on a translator registered in the destination country itself.
Tell us the receiving authority in Finland, the purpose of the document, your filing deadline and the certification format it specifies, and send a photo of the birth certificate and passport page for a first review. We will map out only the steps your file actually needs.
Obtain the birth certificate from District registrar (amphoe) or Bangkok district office, translate it to the accepted standard, have it legalised by the Department of Consular Affairs, then attested at the Finland mission in Thailand where the receiving body requires it.

Thailand acceded to the 1961 Hague Apostille Convention on 30 June 2026 and it enters into force for Thailand on 28 February 2027, so no Thai Apostille is issued yet, so no Apostille is issued in Thailand. The working route is certified translation, legalisation by the Department of Consular Affairs (MFA), and then attestation at the destination country’s mission in Thailand where the receiving authority requires it.
Translation into Finnish, Swedish or English by an authorised translator (auktorisoitu kääntäjä) where the receiving body requires it, and every part of the document must be translated, including stamps, signatures and marginal notes.

It is a public record issued by a state authority, so it can enter consular legalisation directly once an accurate translation is attached.
Connect the names as a chain using change-of-name records or a spelling confirmation, then translate and legalise them together as one bundle.
