要改銀行信地址

本來要更改, 只須要到銀行填寫更改地址申請表就可以. 不過因為你不是戶口存款人, 所以無權這樣做, 你應該先張情況通知銀行, 看看銀行是否有快捷方法. 你要拿著戶主的死亡證去辦理, 但因為涉及戶主的財產資料, 銀行有可能要你去法庭申請遺產索償的手續, 非常不便. 不過既然戶主已不在, 你遲早都是將這些戶口結清, 否則資金根本不能動用, 遲早都會被銀行frozen 戶口.
如果你真的只是想改動地址, 而其他的暫時不想去處理, 另外的一個辦法, 就是去郵局申請 re-direct mail, 將所有寄去舊地址的信件, 轉到新的地址去, 不過此服務須要支付月費.

As you are not the account holder who had passed away, you have no legal right to make any arrangement to the deceased's estate. Only the executor or the administrator of the deceased's estate could do it. So, a legal issue on applying to court for a letter of administrator or a probate that you are the executor as stated in the will of the deceased as recognized in law be made. On getting a confirmed good title on handling the estates, you could then write to the bank for such an address change. To conclude, legal advice or actions must be taken.
