Anyone submitting a change of name certificate in support of a visa application, a civil-status registration, an employment file, or a court or registry filing in South Korea is normally required to submit both the Thai original issued by District registrar 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 change of name certificate back for use in South Korea — 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 South Korea mission in Thailand must attest the document afterwards.
