I. BEFORE THE MARRIAGE
Belgian nationals who wish to marry another Belgian national or a Thai national in Thailand are kindly requested to contact the Thai authorities (‘Amphur’) to verify the exact requirements they need to meet in order for their marriage to take place. At the Amphur, you will learn which documents you need to submit and if they need to be legalized or translated.
The Thai Registrar at an Amphur office usually requires from Belgian nationals an “Affidavit for marriage” that must be made in person at the Consular Section of the Belgian Embassy in Bangkok, and a “Certificate of no diriment impediment”, i.e.an attestation from this Embassy that according to the Belgian law there is no Belgian legal caveat to the marriage of the Belgian national.
