The easiest way to manage the estate’s money is to set up a single estate bank account and a single estate investment account at a single financial institution. Having to juggle several estate accounts on top of all of the deceased’s accounts is a major headache that you don’t need.
That said…….… most financial institutions holding the deceased’s assets will insist that you set up a new estate account with them to accept those assets. At your earliest convenience, have the funds transferred to the financial institution of your choice, consolidating all the assets in a single estate bank account and a single estate investment account. This allows you to leave larger sums in the investment account and quickly move money to the bank account when you need to pay a bill or make distributions, with no transaction costs and only 2 statements to juggle.
