What is the required bank balance for a marriage visa in Thailand: 400k or 800k?

There is some confusion regarding the financial requirements for a Thai marriage visa. Applicants generally need to show 400,000 THB in a bank account if it is solely in their name at the time of application. However, if the funds are held in a joint account, the requirement increases to 800,000 THB, as officials consider the funds as a 50/50 split. Additionally, for certain areas like Jomtien, there may be a requirement for the money to be seasoned in the account for two months prior to the extension.
