Korean Documents for Thailand

Thailand is not a member of the Hague Apostille Convention, so Korean documents cannot be apostilled for use in Thailand. Instead, they require consular legalization — MOFA authentication followed by legalization at the Thai Embassy in Seoul. Whether you are applying for a retirement visa (Non-O), LTR visa, SMART visa, setting up a business under BOI, or registering a marriage at a Thai Amphur, our specialists manage the full legalization chain for all document types.

Frequently Asked Questions

Can I use an apostille for Korean documents in Thailand?

No. Thailand is not a Hague Convention member. Apostille is not valid in Thailand. Korean documents require consular legalization — MOFA authentication followed by legalization at the Thai Embassy in Seoul.

What Korean documents do I need for marrying a Thai national in Thailand?

Marriage registration at a Thai Amphur typically requires legalized Korean civil documents: birth certificate (기본증명서) and a certificate of single status (혼인관계증명서 showing no current marriage), both with certified Thai translation. The Korean Embassy in Bangkok can also issue a certificate of marital status directly.

What Korean corporate documents need to be legalized for a business setup in Thailand?

Thai business registration (BOI investment and company setup) typically requires a legalized Korean corporate registration certificate (법인등기부등본) and a legalized power of attorney. The power of attorney must first be notarized by a Korean notary before MOFA authentication. All documents require certified Thai translation.
