Location & hours
Department of Consular Affairs, 123 Chaeng Wattana Rd, Laksi, Bangkok 10210. Counter hours: 8:30–14:30 Monday–Friday (no service Saturdays, Sundays, or Thai public holidays). The express counter closes at 12:00 sharp.
What to bring
Original document + sworn Thai translation if applicable. Your passport (foreigners) or Thai ID. Cash for fees (no card payments). One photocopy of your ID. If submitting via a representative: a notarised POA + that person's ID.
What happens at the counter
Take a queue ticket at the entrance. Average wait 30–90 minutes. At the counter, the officer scans your document, verifies the issuing authority, collects the fee, and gives you a pickup slip. For normal service you return after 2 business days; express same-day pickup is between 14:00–16:00.
Common rejection reasons
1) Translation not by a recognised translator. 2) Original document missing official seal. 3) Damaged/illegible original. 4) Document type not on MFA's accepted list (e.g., private letters). NYC pre-screens 100% of documents before MFA submission — our acceptance rate is 99.6%.
Can I skip MFA if I have an Apostille from my home country?
Yes — if your document was issued abroad in a Hague Apostille Convention country and is destined for use by Thai authorities (immigration, amphur, court, Land Department), your home country's Apostille is fully sufficient and no additional Thai MFA legalisation is required. The Apostille only needs to be paired with a sworn Thai translation before submission.
Does MFA accept walk-in payment in USD?
No. The Thai MFA legalisation counter accepts only Thai Baht in cash, paid at the cashier desk after document review. There is no card or foreign currency option at the counter. An SCB ATM and a small currency exchange booth are available on the ground floor of the Chaeng Wattana complex for last-minute Baht withdrawals.
Is there an MFA office in Chiang Mai?
Yes. The MFA Department of Consular Affairs operates a regional legalisation office in Chiang Mai that handles a limited subset of document types — primarily birth, marriage, divorce, and education records. Complex multi-document bundles, NAATI translations, and same-day express services still require submission at the main Chaeng Wattana facility in Bangkok.
