Single Status Affidavit for marriage in Thailand — full process

Detailed Answer

To register a marriage at any Thai Amphur (district office), foreign nationals must present a Single Status Affidavit (also called Affirmation of Freedom to Marry). Embassy-specific names: US 'Affidavit of Marriageability', UK 'Certificate of No Impediment (CNI)', Germany 'Ehefähigkeitszeugnis', France 'Certificat de Capacité à Mariage'. Full sequence: (1) book embassy appointment in Bangkok (US/UK/AU/CA same day; Germany 4–6 weeks; France 2–3 months) and sign affidavit; (2) Thai Notary collects from embassy → MFA Chaeng Watthana legalizes the embassy stamp (1–2 days standard, same-day express); (3) we translate into Thai (sworn translator); (4) MFA legalizes the Thai translation; (5) we accompany you (or your authorized agent) to the Amphur in Bangkok / Pattaya / Chiang Mai / Phuket for marriage registration; (6) post-marriage we can prepare a Marriage Certificate translation + MFA + your home-country embassy if you need to register the marriage abroad (e.g. Australia DFAT, US County Clerk, UK GRO). Thai Notary end-to-end THB 8,500–18,500. 3–7 working days from affidavit issue.
