What is the validity period of the affirmation from the British Embassy confirming I am free to marry in Thailand?

I just got one yesterday.

The affirmation is valid for up to 3 months, and you need to specify which month and which province you are registering the marriage in.

As a side not, be aware though, I had to wait about 6 weeks to get an appointment at the British Embassy in Bangkok to get the affadavit.

You will also need to get the affadavit, and a certified copy of your passport (can get the two documents at the same time from the embassy) translated into Thai and legalized by the Ministry of Foreign Affairs.

If you've been married and divorced previously then take that certificate with you too to the embassy

A CONI (certificate of non impediment to marry) is valid for 3-6 months dependant on country you intend to marry in

You have to state the month and province that you will get married in so it is valid for that month

Yes it will expire in 3 to 6 months but recommended it to be used in 30-90 days and best to check with the Amphur you intend to use to get their interpretation of the rules.

If you've been married before, the British Embassy will require your Decree Absolute.

Are you saying the British Embassy in Thailand requires this for them to provide the affirmation you are free to marry documents?

They did not ask me for that, but it was a couple of years ago.

Why! Don’t do it! 😉🤭 this is why…,

In this day and age , less people do it, as so much hassle and expense should it not unfortunately work out!

You do realize you’ll have to renew your visa yearly , 90-Day … You must continue to do your 90-day address reporting at immigration, even with a yearly visa.

Also, You must renew your 1-year extension of stay (Marriage Visa/Non-O) every year, which requires submitting new bank statements and, in some cases, photos of you and your spouse at your home. Which they come knocking at your door, at an unexpected time and date!

My USA friend had to have photo taken sat on double bed together in the bedroom, and they have two children together, married 5 years!

Same with our UK friend, 1 child already expecting another later this year!

Both couples in their early 30’s , wives Thai .

Both have to do sudden boarder runs!

So look at what’s expected from you and know what to expect! so no surprises down the line!

They are cracking down on rules, due to illegals, breaking the rules!

I can only say what’s happened to my friends, others may have a different story!
