Can I use my wife's bank account to prove financial means for a retirement visa in Thailand instead of having my own account?

To obtain a retirement visa in Thailand, it is necessary to demonstrate your financial means through funds in a bank account under your name only. You cannot rely on transfers to your wife's account for the first year unless you have an income affidavit from your embassy. Even with an affidavit, some immigration offices require evidence of income deposited into your own Thai bank account. It is recommended to set up your own account and bring your wife along to immigration if you're using joint finances for proof.
