What documentation will the bank want to see?

As mentioned above, Swiss banks are obliged to verify the identity of a client. For this reason a bank would very much prefer to meet you face-toface for an initial discussion. The bank will certainly want to see official identification papers such as a valid passport or an equivalent official identification document containing a photograph. The bank may also ask for documentation that can prove the origin of your funds, such as the contract for a house sale, a statement from a foreign bank, a receipt from the sale of securities, etc. In the course of the banking relationship the bank may also ask to see documentation connected with specific transactions.
