For extensions based on marriage using banked money method the 400K baht needs to be in a thai bank account in your name only for 2 months before you apply SOME offices want you to leave it in for the 30 days your application goes under consideration
BUT
it is 2 months before for EVERY extension, doesn't matter if it's the first or not.
For banked money method for extensions based on retirement the 800K baht needs to be in a thai bank account in your name only for 2 months before you apply, it needs to stay in the account for 3 months after you get your extension and you can't let the balance go below 400K baht the rest of the year.

it is 2 months before for EVERY extension, doesn't matter if it's the first or not.
