- Court order documenting the fiduciary appointment — the Customer Identification Notice says owners for fiduciaries may be asked at account opening (and from time to time) to provide valid documentation of court orders, in addition to any other documents deemed necessary by the bank; for an executor or administrator that is the Letters Testamentary or Letters of Administration issued by the California probate court

What to know at Bank of the Sierra
Bank of the Sierra publishes no estate-account product page, no estate-account document checklist, and no named estate deposit product — neither the Personal nor the Business Comprehensive Deposit Disclosure (both rev. 06/25/2025, both fetched 2026-07-16) lists a product titled to estates. What the deposit agreement does establish: the Trust & Other Fiduciary Accounts ownership type expressly covers accounts whose legal title is held by an "executor, administrator ... or other fiduciary" under a "court order, or other fiduciary arrangement," so an executor or administrator opens the estate account as a fiduciary-titled account on the bank's standard deposit products; the Customer Identification Notice makes court orders part of the account-opening documentation for fiduciary owners; and the Taxpayer Identification Number clause requires an identification number for every account opened, which for an estate-titled account is the estate's EIN. The agreement also reserves the right to refuse some forms of ownership on any or all accounts. Channels: the bank operates no online deposit-account application of any kind — the sitewide "Open An Account" quick-action lists only "Call 1-888-454-BANK," "Find a Location," and "Send a Message," and every deposit product page's opening CTA is "Visit a Branch" (the only online applications on bankofthesierra.com are loan applications) — so in-branch is the documented opening route and online opening is excluded. Whether an estate account can be completed entirely by phone or by mail, whether a branch appointment is required, and whether all co-executors or co-administrators must appear or sign are stated nowhere on bankofthesierra.com. No Letters recency window, no minimum opening deposit for a fiduciary-titled account, and no opening service level is published. Under the fiduciary clause, the fiduciaries certify they are authorized to manage funds in the account and agree to indemnify, defend, and hold the bank harmless in their individual capacity and jointly and severally.

Frequently Asked Questions
No. Bank of the Sierra states an estate account cannot be opened online. Opening is done in person at a branch.
Bank of the Sierra asks for: Identifying information and photo ID for the opening fiduciary — the Customer Identification Notice states the bank will ask for name, address, date of birth, Tax Identification Number (TIN), and other identifying information, and may ask to see a driver's license, government-issued photo identification, or other identifying documents; Court order documenting the fiduciary appointment — the Customer Identification Notice says owners for fiduciaries may be asked at account opening (and from time to time) to provide valid documentation of court orders, in addition to any other documents deemed necessary by the bank; for an executor or administrator that is the Letters Testamentary or Letters of Administration issued by the California probate court; Identification number for the account — the Taxpayer Identification Number clause requires the bank to obtain an identification number for each account opened or maintained; for an account titled to an estate that is the estate's EIN (IRS Form SS-4), and a Form W-9 TIN certification may be required.
Yes. Bank of the Sierra opens the account under the estate's Employer Identification Number (EIN) from the IRS — the deceased's Social Security Number cannot be used. Getting the EIN is the first step.
Bank of the Sierra's published guidance does not state a co-executor appearance rule. When more than one executor or administrator was appointed, confirm with Bank of the Sierra 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.
