Begin the probate process. Most Estates only need to open a basic checking account so the executor administrator or trustee can take care of all of the estate's expenses.Ask the company or institution (like a bank) that has the property if they have an Affidavit for you to use. These trusts are called testamentary trusts and are usually irrevocable. How is estate property sold? You cannot open an estate account without Letters of Administration but based on the amount involved, Letters are not necessary. Also if it's "Administrator" should it be abbreviated as "ADM" as IRS did on EIN Notice? Once the executor has the EIN, letters of testamentary, and the death certificate, they can open the estate's bank account. This includes personal effects, bank accounts, retirement accounts, real estate, and stocks and bonds. Get the resources you need to help navigate someone else's financial affairs.
