What to know at Prosperity Bank
Prosperity publishes no consumer-facing estate-account opening page: no page on prosperitybankusa.com documents opening channels, appointment requirements, co-fiduciary rules, a Letters recency window, a minimum deposit, an estate-specific account type, or an opening timeline for estate accounts (domain sweep verified 2026-07-16; the Support/FAQs page has no deceased- or estate-account entries). The controlling text is the Fiduciary Accounts clause of the "Terms and Conditions of Your Account" (TX version section 27 / OK version section 28; the PDFs linked from prosperitybankusa.com/terms-and-conditions-of-your-account/ carry Wolters Kluwer form stamps TC-TX 9/1/2020 and TC-OK 9/1/2020): accounts may be opened by a person acting in a fiduciary capacity, including executors and administrators under court orders, the bank is not responsible for the actions of a fiduciary including misuse of funds, and merely opening the account does not make Prosperity a trustee or obligate it to monitor or enforce the terms of the trust or letters. The online account-opening flow (prosperitybankusa.com/open-an-account/, routing to apply.prosperitybankusa.com) enumerates personal checking and savings accounts only. The Wealth Management and Trust Services page covers Prosperity Trust's corporate executor/estate-administration services, not deposit-account opening.

Frequently Asked Questions
Prosperity Bank's published guidance does not state whether an estate account can be opened online.
Prosperity Bank asks for: Court orders establishing the fiduciary appointment — the Fiduciary Accounts clause makes the account openable by persons named "as executors, administrators, or conservators under court orders" and refers to "the terms of the trust or letters" (Letters Testamentary / Letters of Administration are the executor's and administrator's court-issued instrument, though the clause does not name specific documents); Identifying information for the person opening the account, per the agreement's USA PATRIOT Act section (1): name, address, date of birth, and other information that allows the bank to identify you; the bank may also ask to see a driver's license or other identifying documents.
Prosperity Bank's published guidance does not state a co-executor appearance rule. When more than one executor or administrator was appointed, confirm with Prosperity 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.
