My pardons for raising a question that is only tangentially related to visas. My wife and I are currently living here on non-resident O visas. We have an account in my (farang) wife's name alone with 800K baht, and I applied as her spouse. We also have a separate joint account here that we use for everyday expenses.

My question is, if something were to happen to one of us, what would either one of us need to do to have access to these funds? In the USA the accounts may have to go into probate. I'm not sure what would be required here.
