Reader question: Getting married in Thailand to my Thai fiancee

Dear Jeroen, As Hans says and writes, there is nothing more to add. For the Netherlands this is simply a marriage of convenience and not legally valid at all. If you still want to do it right, you have a lot of paperwork to do. For you your birth certificate, proof that you are not married, everything not older than 6 months! This also applies to your future wife, copy of passports (does she have that?) All her papers must be legalized. If all papers are in order, you can get a deed that you can get married.
The website of the embassy is well stated!

Dear Jeroen,
I married my Thai girlfriend last September, only for Thai law and not in accordance with Buddhist traditions. Our marriage has yet to be registered in the Netherlands.

Noah is right that you should have originals of your birth certificate and a statement that you are not married or divorced. You go to the Dutch embassy with these papers and have them verified and translated into English. Cost about 5.000 baht.
Then all these documents must be translated into Thai (by a sworn translator) and then you take these papers and those of your wife (birth certificate, copy ID, house book) to a district office where the marriage papers are arranged. If you have that done in Bangkok, I recommend that you arrange it through a translation-cum-marriage agency (there is one opposite the embassy; one-stop shopping for about 15.000 Baht) because some officials at the district office can be annoying. This certainly applies if you have not lived together in Thailand until now and one can get the impression that this is a marriage of convenience. You can also ask difficult questions at a local district office or ask for photos of the house where you live together, of the Thai family, etc.
NB: After all, there are foreigners who marry a Thai woman for money (I have heard amounts of 200.000 Baht) in order to stay here in Thailand with an associated visa. After receiving the papers, the foreigner goes his own way here. I know Thai women who no longer know who they married or where their 'husband' is.
This whole procedure can be done in a few hours. This is followed by the translation of the Thai marriage documents into Dutch and the registration of the marriage in the Dutch civil registry. That's the stage I'm in right now.

There are also many translators at the Ministry of the Interior, these are considerably cheaper than others (compared to the embassy) and you still have to go there to have it translated. In any case, take an international statement from the municipality with you, which you need to have that contract drawn up at the embassy. Do this in the morning and it will be ready at 12:00. You can also always email me [email protected]

It is the Dutch tax authorities that require you to be married and the marriage registered, in NL, to get all the tax benefits there are, as a married couple.
My marriage is registered with the Dutch Aliens Service, at the City Hall of Rotterdam and in The Hague. My son and daughter are also registered there and can possibly have a. Get a Dutch birth certificate, if necessary, from The Hague. My wife also has a BSN number, formerly a social security number, and receives a tax credit. There are even more advantages.
