Thai-foreigner marriage registration requires coordination across three authorities: your home embassy in Bangkok, the Thai Ministry of Foreign Affairs (Consular Affairs Department on Chaeng Watthana Rd.), and the local district office (Amphur) where you choose to file. NYC Legal processes 800+ couples per year from 50+ nationalities with a 100% success rate.

The single most important document is the Certificate of No Impediment (CNI) — also called Affidavit of Marriageability, Nulla Osta, or Ehefähigkeitszeugnis depending on country — proving you are legally free to marry under your home country's law. Each embassy has its own form, fee (THB 1,500-3,500), and waiting time. We book the appointment, accompany you, and fill in the paperwork.

After the embassy step we (1) translate the document into Thai through a Consular-Affairs-registered translator, (2) legalise it at MFA on Chaeng Watthana (2-3 working days), (3) book the Amphur of your choice — we cover all 50 Bangkok districts and all 77 provinces — and provide certified interpreters (English/Japanese/Chinese/Korean/Russian/Arabic) plus two witnesses on filing day. Finally we translate the Marriage Certificate (Kor.Ror.2 + Kor.Ror.3) back into your language with apostille so you can register the marriage in your home country.
