Do I need to maintain a minimum balance in my Thai bank account for retirement or marriage visa in Thailand?

The user inquires about the bank balance requirements for retirement and marriage visas in Thailand. They plan to retire in Thailand and meet the monthly pension requirement but seek clarification on whether they need to maintain a $400k minimum balance in a Thai bank account, particularly in the context of the first year and their wife's dual citizenship. Based on comments, it is suggested that the $400k does not have to remain in the account but should only be available two months before the extension renewal.
