Detailed Answer
Foreigners marrying in Thailand follow a 5-step legal process: (1) Obtain an 'Affirmation of Freedom to Marry' (single status affidavit) from your home country's embassy/consulate in Bangkok — the embassy usually requires passport, birth certificate, divorce decree (if applicable), and a notarized declaration; (2) The Affirmation must be translated into Thai by a certified translator; (3) Translation is legalized at the Department of Consular Affairs (MFA Chaeng Watthana) — THB 400/page standard or 800/page rush; (4) Both parties appear at any Amphoe (district registrar) with passports, MFA-legalized Affirmation, and 2 Thai-speaking witnesses to register the marriage and receive the Khor Ror 2 / Khor Ror 3 marriage certificate; (5) Optional: get the Thai marriage certificate translated and legalized for use in your home country (often required for spousal visas, name changes, immigration). NPT handles all 5 steps including witness arrangement and embassy appointments — THB 9,500–28,500 depending on nationality and complexity.
