How do I open an estate account?Just make an appointment at your local financial center and an associate will be happy to assist you. Begin the probate process. When you open a bank account for the estate, the account name must indicate that it is an estate account and not your personal account. These trusts are called testamentary trusts and are usually irrevocable. Estate Bank Account is a Bank Account set up to collect the deceased person's cash assets and pay the bills of the estate. 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.
