its a serious case! all these documented release of money will work only if wife's name is a nominee in the account otherwise one will have to prove it!

but if there is a debit card (visa ), I think one can withdraw from any of the ATM in their home country. I have done this once when i was in India and I had an account in one of the Omani banks. I withdrew money from a local ATM using the visa electron debit card.

Hope it works!!!
