What are the financial requirements for renewing a dependent extension in Thailand?

To renew a dependent extension for another year in Thailand, you need to meet certain financial requirements depending on your visa basis. If you are applying based on marriage to a Thai national, you must have either 400,000 THB in a Thai bank account in your name for the two months prior to the application or a monthly deposit of at least 40,000 THB for the last 12 months into your Thai bank account. Printed UK bank statements may not suffice for these requirements.
