Note: Please type or print neatly in black or blue ink.In order to open a checking account, you generally need to present to the bank a copy of the death certificate as well as your legal appointment paperwork. Begin the probate process. File the form, the decedent's will (if there is one), and a certified copy of the death certificate with the county probate court where the decedent lived. To close a bank account on behalf of someone who has passed away, you must have legal authority to manage the account.
