TLDR : Answer Summary

A Certificat de Coutume is a document needed for marriage formalities in certain countries, such as Luxembourg. It can be obtained through a Thai embassy, specifically from the Thai Embassy in Brussels for those looking to marry there. The comments also clarify that a Thai citizen does not need this document when in Thailand, as the country recognizes adults from the age of 20.

@Steve ******

Are you looking for a « Certificat de Coutume » / " Akte van gewoonterecht " in order to do a publication of marriage in Luxembourg??

if so, then have your Thai wife request it from the Thai Embassy in Brussels

A Thai embassy in a foreign country issues this document. It's not needed in Thailand as the law in Thailand says a 20 year old is an adult.

In order for the Thai wedding to be recognized in Luxembourg later, I have to submit several documents first

I need to show the authority in my country the Certificate of residence; Birth certificate and Certificate of celibacy from my future wife.

The last document I need is the one from the picture

Then they will do a public announcement in Luxembourg

Only then they can give me the certificate of marital capacity that I can bring with me to Thailand

I'm assuming that's a language thing and it's actually the certificate of single status to say you're not already married

You indicate a “Thai wedding”. If so, you have a Thai marriage certificate which can (should) be translated and verified in Thailand.

That suffices as proof of marriage and can be registered in your country.

Before that even happens, my municipality in Luxembourg wants to see this document from my photo, which explains the rules in Thailand regarding marriage. Otherwise, they won't be able to issue me a document confirming that I can get married and that I can then bring with me to Thailand.

Wow! So they would effectively refuse a legal foreign document even after being confirmed by their own embassy?

Unbelievable!

as you are from Luxemburg you need to use the thai embassy in Brussels as this one is responsible for people from Luxemburg as well so you need to get the document from them.
