You have 3 ways to meet the proof of funds
ALL banked money 800K baht in a thai bank account in your name only
ALL monthly income where you transfer in from abroad to a thai bank account in your name only a minimum of 65K baht a month each month every month for the previous 12 months
A combination of banked money and monthly income that totals 800K baht for the year (12 monthly transfers and the banked money amount)
