When a decedent, or a person who dies, leaves a will, a proceeding must be completed in the Surrogate's Court to probate or prove the will. You should also make a list of what the Decedent owned at the time of death (such as bank accounts, house, stocks, etc.).The bank will not allow you to close it unless you have a letter of authorization from the probate court. To close a bank account on behalf of someone who has passed away, you must have legal authority to manage the account. If submitting online, you must provide your Social Security number for verification. A New York City bank account beneficiary lawyer can help you advance your interests. Bank accounts that are solely in your name can be held up temporarily upon your death. There will be a personal representative appointed and letters of administration will be issued so that he or she may complete the administration of the estate. It does not have these records for New York City (the boroughs of Manhattan, Kings (Brooklyn), Queens, Bronx, and Richmond (Staten Island)). You will fill out the relevant paperwork, including the Petition, and the Proposed Order.
