Opening an Estate Account: Documents Banks Require

9/27/2026

An executor walks in with a folder of papers, a death certificate and a question: "How do I open an account for my mother's estate?" Handled well, this becomes a clean fiduciary relationship. The bank knows who has authority, the account carries the right taxpayer number, and every dollar in and out can be traced when the estate closes. Handled badly, it becomes an account opened under the decedent's Social Security number, a signer whose authority was never checked, and post-death federal benefits mixed in with the estate's money.

This post is a bank onboarding checklist for opening an estate bank account. It covers who can open one, what each document proves, how to title the account, how CIP and beneficial ownership apply, and the problems to watch for after opening. The court documents and the personal representative's powers are set by state probate law, so treat the specifics below as the pattern to build on, not a substitute for your state's statute and your counsel's guidance.

Who Can Open an Estate Account

An estate account is opened by the personal representative, the person a probate court has appointed to administer the decedent's estate. State terminology varies:

An executor is named in the will and appointed by the court.
An administrator is appointed when there is no will, or when the named executor cannot serve.
Some states use "personal representative" for both, and some use other titles for administrators with a will annexed or special administrators.

Whatever the title, the court's appointment is what gives the person authority. Being named in the will is not enough. Until the court issues its order, the named executor has no authority over the decedent's accounts, and the bank should not open an estate account for them or release funds to them.

Family members also cannot open an estate account just by being the decedent's child or spouse. If they are claiming as heirs under a small estate affidavit, that is a different process with different documents, and most banks do not open an estate account for an affiant at all.

The Core Documents

Letters testamentary or letters of administration

This is the document that matters most. Letters testamentary (when there is a will) or letters of administration (when there is not) are the court's certification that the named person has been appointed and is authorized to act for the estate. Some states use a different name, such as letters of authority or letters of office.

What to check:

It is a certified copy from the court, not a photocopy of a certified copy. Courts usually stamp or seal certified copies.
It is recent. Many banks require letters certified within a set period, so they reflect that the appointment is still in effect. That is a bank policy choice, not a federal rule. Set your own period and apply it consistently.
It names the person in front of you, and the name matches their identification.
It shows any limits. Some letters or court orders restrict what the representative can do: requiring court approval for withdrawals, requiring a bond, or naming co-representatives who must act together. Read the whole document, including any attached order.

If the letters say funds must be held in a restricted or blocked account, withdrawals require a court order, and your system must enforce that. Recording the restriction in a notes field that nobody reads is not enough. Staff who rarely see probate documents can get grounding in what letters, wills and court orders mean in Wills, Trusts and Estate Administration.

A certified death certificate

The death certificate confirms the death and the date of death, which matter for reclamation of federal benefits, for the decedent's own accounts and for the tax year. The letters already presume the death, but most banks also keep a certified death certificate in the file.

The estate's employer identification number

An estate is a separate taxpayer from the decedent. According to the IRS Instructions for Form 1041, a domestic estate with gross income of $600 or more for the tax year must file Form 1041, and every estate required to file Form 1041 must have an EIN. The personal representative applies for the EIN, which can be done online, by fax or by mail.

From the bank's side, the rule is simple: the estate account is reported under the estate's EIN, never the decedent's Social Security number. Interest earned on estate funds belongs to the estate, and the information return should show the estate as the recipient. Get a Form W-9 from the personal representative certifying the estate's EIN. Our post on 1099 reporting for banks covers the reporting side.

Personal representatives often ask whether they can use the decedent's SSN "just to get the account open." They cannot, and the answer should come with an explanation, not just a refusal. The IRS also expects the personal representative to file Form 56, Notice Concerning Fiduciary Relationship. That is the representative's filing, not the bank's, but it is a helpful pointer when they ask what else they need to do.

The personal representative's identification

The personal representative is the signer and controller of the account. Verify their identity the same way you would for any individual with authority on a non-individual account.

Optional or situational documents

A copy of the will, if the letters are testamentary. Some banks request it for the file. It is not usually needed to establish authority, since the letters already do that, but it can help when the will limits the executor's powers.
A court order for any specific action outside the representative's ordinary authority.
Documents for co-representatives, if more than one person was appointed.

CIP and Beneficial Ownership for Estate Accounts

The estate is the customer

The Customer Identification Program rule for banks, at 31 CFR 1020.100 and 1020.220, defines a customer as a person that opens a new account. The BSA's general definition of "person" at 31 CFR 1010.100 expressly includes a trust or estate. The estate is the customer, and the personal representative is the individual acting for it.

For a non-individual customer, CIP requires the bank to verify that the customer exists. For an estate, the court's letters are the natural documentary evidence. The CIP rule also allows the bank, based on risk, to obtain information about individuals with authority or control over the account, which here means the personal representative. Most banks verify the representative's identity as a matter of course.

Beneficial ownership certification

FinCEN's customer due diligence rule at 31 CFR 1010.230 requires beneficial ownership information for a legal entity customer, defined as a corporation, LLC or other entity created by filing a public document with a secretary of state or similar office, a general partnership, and similar foreign entities. A probate estate is not created that way, so it falls outside the definition as written. Your bank's CDD policy may still call for more information based on risk, such as the expected size of the estate, the source of funds and the expected activity.

The Corporate Transparency Act's beneficial ownership reporting to FinCEN is a separate regime that applies to reporting companies, not to the bank's account-opening rule. Don't mix them up in your procedure.

OFAC and CDD

Screen the estate account's parties under your normal OFAC procedures. That includes the personal representative and, depending on your policy, the decedent's name as it appears on the account. Record the account's purpose and expected activity. Estate accounts usually have a short, understandable life: collect assets, pay debts and expenses, distribute to heirs, close. Activity that does not match that pattern is worth noticing. Our post on KYC and customer due diligence covers the broader framework.

Titling the Account

The title should make the fiduciary capacity obvious to anyone who looks at it, including a later teller, a court, an auditor and the FDIC. A common form is:

Estate of [Decedent's full name], [Representative's name], Executor (or Administrator, or Personal Representative)

The ownership rules follow from that:

No right of survivorship. If the representative dies or is removed, the account belongs to the estate and passes to a successor representative, not to the representative's heirs.
No POD beneficiary. The estate's assets are distributed under the will or intestacy law, not by account designation.
No joint owners. Co-representatives are signers in the same fiduciary capacity, not co-owners.
The estate's EIN as the account's taxpayer number.

Co-representatives

When the court appoints two or more representatives, whether either can act alone or both must act together depends on the will, the letters and state law. Unless the documents clearly say one can act alone, the safe default is to require both signatures and to build that into the account's signing rules.

Funding the Account

Once open, the estate account becomes the hub for the estate's money. A few items need attention.

Moving the decedent's own accounts. Balances in the decedent's individual accounts, with no POD designation or survivorship, belong to the estate and can be moved into the estate account on the personal representative's instruction, supported by the letters. Accounts with a POD beneficiary or a surviving joint owner do not belong to the estate and should not be swept into it.

Checks payable to the decedent. Refund checks, final paychecks and similar items payable to the decedent can generally be endorsed by the personal representative and deposited to the estate account. Your deposit agreement and endorsement procedures should say how.

Federal benefit payments. Do not let post-death Social Security or other federal benefits be moved into the estate account as if they were estate assets. They are subject to reclamation under 31 CFR Part 210. The Fiscal Service's Green Book says a release of funds to an executor or other party acting for the decedent's estate is treated as showing that the bank knew of the death. From that point, the Green Book says, the bank is fully liable for later post-death federal payments and for any post-death benefits already in the account that it then allows to be withdrawn.

Safe deposit boxes. Authority over the estate's deposit accounts does not automatically mean the representative may remove a box's contents without your box procedure being followed. Box entry after a death is its own process. See our post on safe deposit box operations.

Monitoring and Closing the Account

Estate accounts are fiduciary accounts, and the bank is not the representative's supervisor. Still, some patterns should be noticed and, where appropriate, escalated:

Large transfers to the representative personally early in the administration, before creditors and taxes would normally be paid
Cash withdrawals with no obvious estate purpose
Commingling, such as the representative's own payroll deposits or bills paid from the estate account
Activity after the representative's authority has ended, because the letters were revoked, the estate was closed or a successor was appointed

The representative's authority depends on the court's continuing appointment. When the estate closes, or a successor representative presents new letters, update the signers and close or retitle the account. Keep the full file: letters, death certificate, EIN documentation, W-9, signature card, court orders and closing records.

Our posts on estate settlement and the trust department's role and trust administration fiduciary responsibilities explain what the representative is supposed to be doing with the money, which helps deposit staff recognize when something is off.

Training for the People Who Open These Accounts

Estate accounts are uncommon enough that many branch staff see only a few a year, and that is why they go wrong. The Wills, Trusts and Estate Administration course is the place to start for deposit and trust staff who need to understand the probate documents and fiduciary roles behind an estate account. Teams that want to compare options can browse the trusts and estates course page.

Frequently Asked Questions

What documents do you need to open an estate bank account?

Banks typically require certified letters testamentary or letters of administration from the probate court, a certified death certificate, the estate's employer identification number with a Form W-9, and identification for the personal representative. Some banks also ask for a copy of the will and any court orders that limit the representative's authority. Exact requirements are bank policy built on state probate law, so representatives should ask their bank before they visit.

Can an executor open an estate account before being appointed by the court?

No. Being named as executor in a will gives no authority over the decedent's accounts until the probate court appoints the person and issues letters. Before that, the bank should not open an estate account for them or release the decedent's funds to them. If something urgent comes up before appointment, state law may provide special or temporary administration, which also produces a court order the bank can rely on.

Does an estate need its own EIN to open a bank account?

In practice, yes. Every estate required to file Form 1041, generally one with gross income of $600 or more, must have an EIN. Banks report interest on estate accounts under the estate's EIN, not the decedent's Social Security number, so they almost always require the EIN at opening. The personal representative can apply online, by fax or by mail.

Who owns an estate checking account?

The estate does. The personal representative controls the account in a fiduciary capacity but does not own the funds personally. The account has no survivorship and no payable-on-death beneficiary. If the representative dies or is removed, a successor appointed by the court takes over the account. The money is distributed under the will or state intestacy law when the estate is settled.

Is an estate a legal entity customer for beneficial ownership purposes?

FinCEN's CDD rule defines a legal entity customer as a corporation, LLC or similar entity created by filing with a secretary of state, plus general partnerships and similar foreign entities. A probate estate is not created that way, so the beneficial ownership certification requirement does not reach it as written. The estate is still a CIP customer, and banks typically identify the personal representative and set risk-based expectations for account activity.

Can post-death Social Security payments go into the estate account?

They should not be treated as estate funds. Federal benefits paid after death are subject to reclamation by Treasury under 31 CFR Part 210, and the SSA cannot pay for the month of death. The Fiscal Service treats any release of funds to an executor as evidence that the bank knew of the death. Identify post-death federal deposits in the decedent's account and handle them under your reclamation procedure.
