Marrying in Thailand vs Marrying Abroad: Paperwork Compared
Since Thailand's marriage equality law took effect on 22 January 2025, district offices register marriages regardless of the couple's gender, which makes Thailand a practical venue for many international couples.
In short
Registering in Thailand needs an affidavit of freedom to marry from your embassy, translated into Thai and legalised by the Department of Consular Affairs, then the district office issues the certificate the same day. Registering abroad follows the local registry's rules, and the resulting certificate must be legalised and translated before Thailand recognises it.

Choose Register in Thailand (amphoe) when
- Both partners can attend a Thai district office in person
- You want a same-day certificate with predictable steps

Frequently asked questions
- Does marriage equality change the documents required?
- The document list is the same for all couples. Some embassies updated their affidavit wording, so we confirm the current form before you book an appointment.
- How long is an affidavit valid?
- Most district offices expect it to be recent, commonly within three months, and the translation must be legalised after the affidavit is issued.
- Do we need a prenuptial agreement?
- It is optional, but in Thailand it must be registered together with the marriage to be enforceable, so decide before the registration date.
- Can you handle the whole file?
- Yes, from the embassy appointment and translation to legalisation and the district office visit, with an interpreter present. Contact us by LINE @NAATI.
