What are the rules for using the banked 400,000 baht?

I will need to use the money on Friday and will replace it in smaller amounts back up to 400,000

TLDR : Answer Summary
The discussion centers around the 400,000 baht requirement for applying for an extension of stay based on marriage in Thailand. It highlights that while most immigration offices do generally expect this amount to be maintained in the applicant's account for two months prior to applying for the extension, this is not enforced as an official rule and varies by office. Once the extension is granted, there is no longer a requirement to keep the funds in the account. The comments also compare this requirement with that of retirement extensions, noting that the financial requirements are stricter.

For an in country Non-O Visa (90 days) 400k in a Thai bank account on the day you apply then again 400k for 2 calendar months before you apply for the 12 month extension

if your 50plus you can get an extension on a non o visa based on retirement BUT the requirement is 800k plus

I'm not retired. I need a visa for a year to be with my wife. We're building a resort in Koh Samui.

@Giovannone ******
then 400k all good I was on samui December 2006

Wish it was the same for extension based on retirement you think based on marriage it would be more but based on retirement its double !

Sorry Tod. Am I missing something .

Shouldn’t that read most offices dont request keeping the ฿400k in your account. And like you reiterated at the end it’s not a rule. So you’d say to the IO could you point that out to me in the rules. And thank him for clearing this up and be on your way. They might ask to see your bank book again. Which you would show them and it would show your activity of your account over the under consideration stamp period. Most offices don’t request that. It’s very different to a retirement financial requirements most importantly the one of being married only 2 months seasoning nothing else. Your wife might only want to give her money for two months.!

MOST offices request you keep the 400K baht in the account during the "under consideration" period from the stamp you get when you apply for the extension. but it is not an official rule.

@Martin *******
check the retirement at your immigration office

@Ian ********
We are talking about marriage and it’s two months seasoning is all that’s required for marriage financial requirements. You can do as you please and want after that. No need to keep the ฿400,000 in after you have your under consideration stamp in your passport. Retirement requirements are totally different and more financially restrictive.

@Martin *******
dont I know,I'm luckey 800k is not a problem for me BUT when i get proof from bank this month i will ask them what they will need when i die,im 61 already older than my father and grandfather!
Martin ********
@Ian ********
I’m 68 all the best to you
Tod *********
@Martin *******
yep, left out the DON'T as in most offices don't require you to keep the funds in during the under consideration stamp, sorry thanx for catching it
Tod *********
The rules for the seasoning of funds for an extension based on marriage using banked money method are 400K baht in a thai bank account in your name only for 2 months before you apply for the yearly extension

MOST offices don't (thanx
@Martin *******
) request you keep the 400K baht in the account during the "under consideration" period from the stamp you get when you apply for the extension. Some do, but it is not an official rule

Once the year extension is inked into your passport there's no obligation to keep the funds in the account any longer.

Where are you in the process of your visa/extension etc???
John ****
If you have Bangkok bank they now need to see it in there for 4 months prior to the visa application otherwise they lock the 400k for 4 months (I learned the hard way) So if you have BKK bank and need that money after being approved the visa make sure you have it in there 4 months or more before to avoid the lock.
Tod *********
then you're fine to do what ever you want with the funds as long as it's 400k for 2 months before you're going to apply for the next yearly extension you're fine

@Tod ********
wasn't it, 2 months before application+ 1 month(under consideration period)?
Graham ******
@Caner ******
Read Tod's answer above
James ********
@Caner ******
yes...to be safe...it's best to keep the funds in the bank account during the normal one month Under Consideration period.
Caner *******
At least in Bangkok, chaengwathana, they asked me to keep the money in the account in the under consideration period and they asked for an updated bank book that shows i still keep the money until the day i my extension is approved.
