What to know at Mechanics Bank

Mechanics Bank opens fiduciary accounts under the "Trust and Other Fiduciary Accounts" ownership type in the Personal Account Agreement (effective March 23, 2026), which expressly names an executor or administrator as a signing party holding legal title under a court order -- that is the estate account an appointed personal representative opens with Letters and the estate's EIN. The bank publishes no estate-account product page and no estate-specific opening procedure: no channel statement (its How to Apply page describes only "Visit your local branch to complete the application" for personal checking and savings, so in-branch is the one documented opening channel), no appointment rule, no co-fiduciary signing rule, no Letters recency window, no estimated time, and no estate-specific account type. The agreement requires a certified TIN for each account and lets the bank refuse an account without one, but it does not state whether the estate's EIN confirmation letter must be in hand before opening. Deposit-account questions run through Customer Care at 800-797-6324 or any branch; Wealth Management Trust & Estate Services (925-482-8060) is the bank-as-fiduciary line, not the estate deposit-account desk.

Frequently Asked Questions

Mechanics Bank's published guidance does not state whether an estate account can be opened online. Its stated channel is in person at a branch.

Mechanics Bank asks for: Court order documenting the fiduciary appointment (Letters Testamentary or Letters of Administration) -- the Personal Account Agreement states that owners for fiduciaries "may also be asked at account opening and from time to time to provide us with valid documentation, including select pages of trust agreements (or certifications of trust), court orders, and any other documents deemed necessary by us"; Name, address, date of birth, and a driver's license or other identifying documents for the person opening the account (federal customer-identification disclosure on the bank's How to Apply page); A certified taxpayer identification number for the account -- the agreement requires a TIN for each account opened and says the bank "may refuse to open, and we may close, any account for which you do not provide a certified TIN"; for an estate account that is the estate's EIN.

Mechanics Bank's published guidance does not state a co-executor appearance rule. When more than one executor or administrator was appointed, confirm with Mechanics Bank whether all must attend.

An estate account is a bank account titled to the estate itself — not to the person who died and not to the executor personally. The court-appointed executor or administrator opens it to deposit money owed to the estate (final paychecks, refunds, proceeds from closed accounts), pay the estate's debts and expenses, and distribute what remains. Checks made out to "the Estate of" can only be deposited into an account titled this way.

The estate is its own taxpayer, separate from the person who died. Banks open estate accounts under the estate's Employer Identification Number (EIN) from the IRS, not the deceased's Social Security Number. The free EIN application prepares IRS Form SS-4 for the estate.
