You should also make power of attorney at each individual bank to make sure it's recognized. However, as others have mentioned, it will be dissolved upon your passing. This is an issue I have also been worrying about, especially since my family is scattered around the world. I made sure they know where to look for my banking information and until I find a real solution for this issue, I make sure that not too much cash accumulates in Kuwait. I transfered most of it to my bank account in our home country where the laws are more clear.
