In order to get married its my understand that i have to go to the embassy and get a document saying that i am not currently married.

Then i have to take the form to a translation shop and get it rewritten in Thai.

Then i have to go and get the translation authenticated? To check it is accurate? But where do i go to get this done? Back to the embassy?

I had a court document translated and authenticated at,

AC Translation Service

Gian Kwan Building, 11th floor, Wireless Rd.

They did it all.

It's much easier to have a one stop shop handle it all as Skipper said. If you choose to do it yourself as I did (My Thai wife is incredibly cheap) you have to take the translated document to the government office out near the airport (Laksi) to have it legalized. If I remember correctly the fee is quite small BUT if you want it the same day you must pay an express fee. I think it was 500 baht.

You fill out a form at your Embassy that confirms your are not married and are fit to support a wife with a little bio type data. The Embassy provides its stamp and you take to translation service. The service translates into Thai and can also register it for you. If you just translate you must take to Chaing Watanna Road office of the MFA (same building as passports issued) to have it registered. Once that is done you can go to a District Office and register your marriage. The document will have a registration number and the District may well check that out.

See also Marriage.

Before the embassy provides you with the paper stating that you are free to marry , you also need to get a certificate of 'no criminal record' from your country.

I remember there are other requirements like 'salary slip, proof of employment' , 'income tax papers stating that you pay tax in your country' , 'certificate of no crimial record' , 'divorce papers if any' and 'certificate that certifies that your girlfriend has not worked in your country before .'

That is the requirement for my country's embassy. I think it might vary from country to country

You need to double check with your embassy.

None of the above was required.

Getting the translation/legalization was actually really easy.

After stepping out of the US embassy welding the stamped paperwork i was immediately surrounding by a swarm of translation office workers, so i just kind of went with the flow and paid 300 baht for the translation and 1000 baht to get them to take it for legalization (could have paid 500 but i wanted next day instead of 3 day).
