Estate Bank Account Documents and MSG Rules (2026)

An estate bank account lets the personal representative collect money that belonged to someone who died, pay estate bills and taxes, and distribute what remains. Most banks will ask for proof of death, proof of authority, an estate EIN, and the personal representative's ID before they open or let you control the account.

This guide explains the documents banks usually request, when a Medallion Signature Guarantee may come up, and how Sunset can help organize the bank file as part of the estate settlement. This is general information, not legal advice.

What an estate bank account is for

An estate bank account is opened in the name of the estate after someone dies. It is used to hold estate money while the personal representative works through bills, taxes, account closures, transfers, and final distributions.

Families often need one when money is coming in from several places, such as:

• Closed bank accounts in the decedent's name
• Refund checks made payable to the estate
• Investment account proceeds that belong to the probate estate
• Proceeds from sold property
• Payments owed to the decedent before death

The account helps keep estate money separate from personal money. That separation matters because executors and administrators usually need clear records showing what came in, what was paid, and what was distributed.

For a broader look at the account-opening process, see Sunset's guide to how to open an estate bank account.

Who has authority to open and control the account

Banks usually look for proof that you have authority to act for the estate. That proof often comes from a probate court, such as Letters Testamentary when there is a will or Letters of Administration when there is no will.

In some small-estate cases, state law allows a small-estate affidavit to be used in place of full probate authority. Whether a bank accepts that affidavit depends on state law, the type of asset, and the bank's own review process. Sunset has a plain-English overview of small estate affidavits if you are trying to understand that path.

The IRS also recognizes Letters Testamentary, Letters of Administration, or Form 56 notice of fiduciary relationship as evidence that a person may act for an estate. This lines up with what banks usually ask for before they share information, close accounts, or move funds.

Documents most banks ask for

Banks can request different combinations of documents based on the account type, the decedent's domicile, the state, and whether probate is open. Still, most estate bank account files start with the same core items.

Document	Issued by / where to get	Purpose for the bank	Practical notes
Certified death certificate	Vital records office or funeral director	Confirms the death, identity, and domicile of the customer	Many banks accept legible copies; some situations require certified originals.
Letters Testamentary (will) or Letters of Administration (no will)	Probate court	Proves your legal authority to act for the estate	In small-estate states or cases, a state-law affidavit may substitute.
IRS EIN (estate tax ID) and EIN confirmation letter	IRS, Form SS-4, online, fax, or mail	Satisfies the bank's Customer Identification Program (CIP) for the estate's taxpayer ID	Estates require their own EIN; online issuance is immediate when available.
Personal representative's government ID and address	Executor or administrator	Satisfies CIP/KYC identity verification for the signer	Banks must collect name, DOB, address, and ID under 31 C.F.R. §1020.220.
Affidavit of domicile (often for brokerage/securities)	Executor; sometimes a court form	Establishes the decedent's state of legal residence for transfer and tax waivers	Common in securities transfers; requirements vary by firm.
Trust documents (if assets are titled to a trust)	Trust instrument or certification	Confirms trustee succession and powers	Trust-titled assets generally bypass the probate estate.
Court orders for special actions	Probate court	Authorizes certain distributions, sales, or account changes	Required in dependent administrations or disputed estates; varies by state.

Quick bank checklist before you go

Before you call or visit a bank, try to gather the items most likely to be requested. Having a complete file can reduce delays and repeated document requests.

• Get an EIN for the estate. Apply with the IRS and keep the EIN confirmation letter for the bank's file.
• Gather court authority. Bring certified Letters Testamentary or Letters of Administration, or a state-approved small-estate affidavit if it applies.
• Bring a certified death certificate. Some banks will accept a clear copy, but some situations require a certified original.
• Prepare your ID. The personal representative's government ID, address, and date of birth are needed for bank Customer Identification Program checks. Bring proof of address if the bank asks for it.
• Collect supporting documents if needed. These can include a trust certification for trust-titled assets, an affidavit of domicile for brokerage transfers, and court orders for restricted, guardianship, or dependent administrations.
• Decide how the account should be titled. A common format is "Estate of [Name], by [Your Name], Personal Representative."
• Ask whether all co-representatives must appear. If more than one person was appointed, the bank may need each person to sign or complete identity checks.

Questions to ask the bank before opening the account

A short call can save a second trip. Banks have their own document review rules, and branches may need to confirm requirements with a back office team.

Ask the bank:

• Do you require the estate EIN at account opening, or will you accept it within a set timeframe?
• What forms of court authority do you accept: original Letters, certified copies, or a small-estate affidavit?
• Do your Letters Testamentary or Letters of Administration timing rules require recent copies?
• Who must appear in person?
• Do you allow remote onboarding or KYC-only onboarding for out-of-state personal representatives?
• What CIP/KYC items do you collect for signers, such as ID, SSN/EIN, proof of address, or date of birth?
• Are any W-9 or W-8 forms required for beneficiaries or co-fiduciaries?
• Will any incoming transfers, especially from brokerages or transfer agents, need a Medallion Signature Guarantee instead of notarization?
• How should the estate account be titled on statements and checks?
• Will you place initial holds on large deposits or close-out checks?

EIN timing for an estate

An estate needs its own EIN. The decedent's Social Security number should not be used as the estate's taxpayer ID after death for the estate account.

The source timing is:

• Online IRS issuance is immediate when available.
• Fax is typically about 4 business days.
• Mail may take about 4 weeks.

Many families plan the account opening once they have both the EIN confirmation letter and proof of authority in hand. Banks usually do not start full processing until the package is complete.

How FDIC coverage works for estate accounts

For FDIC purposes, decedent or "estate of" accounts are insured in the Single Accounts category as if owned by the deceased. The standard amount is aggregated up to $250,000 per insured bank.

Additional coverage can apply through different ownership categories or bank programs. The FDIC's EDIE tool can help estimate coverage based on the account setup and institution.

Accounts coordinated through Sunset with partner banks are FDIC-insured. The source program described coverage up to $3 million through partner banks.

What a Medallion Signature Guarantee is

A Medallion Signature Guarantee, often shortened to MSG, is a special signature authentication used mainly for securities transfers. It is not the same as notarization, and a notary public is not a substitute.

Transfer agents and fund companies may ask for an MSG when securities are being transferred, re-registered, or paid out. This can happen even if the bank opening the estate deposit account does not need one.

Recognized Medallion programs include:

• STAMP
• SEMP
• NYSE MSP

Common MSG triggers include:

• The dollar amount is large, often in the $50,000 to $500,000+ range.
• The payment address differs from the address on file.
• The bank instructions differ from the instructions on file.
• Ownership is changing.
• Identity cannot be verified another way.

The practical point is simple: opening an estate bank account may be a normal deposit-account process, but moving brokerage assets into that account can create a separate transfer-agent requirement.

Timing and sequencing to expect

The order of tasks matters. A bank may not be able to open the estate account until identity checks are complete, and another institution may not transfer funds until it sees the estate account details.

A common sequence looks like this:

1. Order death certificates.
2. Get court authority or confirm whether a small-estate affidavit is allowed.
3. Get the estate EIN.
4. Gather the personal representative's ID and address information.
5. Ask the bank about its estate account requirements.
6. Open the account once the bank file is complete.
7. Transfer or deposit estate funds into the account.
8. Pay valid estate expenses and taxes.
9. Keep records for probate court, tax filings, and beneficiaries.
10. Make final distributions when the estate is ready.

Banks must verify identity and taxpayer information under CIP rules and retain records. They may restrict activity until verification is complete.

Edge cases that change the documents

Some assets do not move through a normal estate bank account process. Others need added paperwork before they can be transferred.

POD and TOD accounts are a common example. Payable-on-death and transfer-on-death accounts usually pass outside probate to the named beneficiary after proof of death and identity. Beneficiary designations override conflicting terms in a will. For more detail, see Sunset's guide to payable-on-death bank accounts.

Joint accounts with rights of survivorship also often pass outside probate. The surviving co-owner typically keeps the account, though the probate estate may still need information for accounting.

Trust-titled assets are different again. Banks and brokerages may ask for trust documents or a trust certification and successor trustee IDs instead of probate Letters. Trust-titled assets generally bypass the probate estate.

Non-U.S. heirs can add tax paperwork. Transfer agents often require forms such as Form W-8BEN and may require a Medallion Signature Guarantee.

Small-estate procedures can also change what the bank asks for. Some states allow a small-estate affidavit to collect assets without full probate, and many banks accept these affidavits when state law allows.

How Sunset helps coordinate the estate account

Sunset is not a bank and does not replace the authority a court gives to a personal representative. The executor or administrator keeps approval and control. Sunset helps prepare, package, and coordinate the materials that banks and transfer agents need.

Here is how Sunset can help:

1. Confirm authority and identity. Sunset securely collects the Letters and ID, then checks them against court and data sources so banks receive a clean file.
2. Obtain the estate EIN. With authorization, Sunset files for the estate's IRS EIN so the bank's CIP requirements can be met.
3. Coordinate the estate bank account with a partner bank. Sunset helps with the application, KYC package, and signer permissions. The estate account is FDIC-insured.
4. Search for assets. Sunset searches 2,300+ financial institutions to find accounts and assets that may belong to the estate.
5. Consolidate eligible assets. Sunset helps close and transfer eligible bank, investment, and other financial accounts into the estate account, tracking each institution's requirements and arranging Medallion Signature Guarantee support when a transfer agent demands it.
6. Prepare probate paperwork. Sunset generates state- and county-specific probate packets and refers families to a local probate attorney when counsel is needed.
7. Support payments and distributions. You pay bills and taxes from the estate account. When the estate is ready, Sunset prepares distribution records that can support probate court and tax filings.
8. Keep records. Sunset is SOC 2 Type II certified and keeps an auditable trail aligned with bank CIP and probate reporting expectations.

Sunset's family product is funded through our bank partnership. The estate does not pay Sunset, and all assets go to the beneficiaries and heirs.

Sunset has helped 15,000+ families settle estates.

FAQ

What documents do banks usually need for an estate account?

Most banks ask for a certified death certificate, Letters Testamentary or Letters of Administration, the estate's EIN confirmation letter, and the personal representative's government ID. In some small-estate cases, a qualifying affidavit may be accepted instead of probate Letters. Brokerages or transfer agents may also ask for an affidavit of domicile, trust certification, court orders, or tax forms.

How fast can I get an EIN for an estate?

Online IRS issuance is immediate when available. Fax is typically about 4 business days, and mail may take about 4 weeks. Keep the EIN confirmation letter because banks often want it in the account file.

Is an estate bank account FDIC-insured?

Yes, decedent or estate accounts are treated in the FDIC Single Accounts category as if owned by the deceased, aggregated up to $250,000 per insured bank. Additional coverage can apply through different ownership categories or bank programs. Accounts coordinated through Sunset with partner banks are FDIC-insured, and the source program described coverage up to $3 million through partner banks.

Do I need a Medallion Signature Guarantee to open an estate bank account?

Usually, no. A Medallion Signature Guarantee is mainly used for securities transfers, not ordinary deposit-account openings. A brokerage, fund company, or transfer agent may require an MSG if assets are being transferred, ownership is changing, instructions differ from what is on file, or the value is large.

Who owns and signs on the estate account?

The account is commonly titled "Estate of [Decedent], by [Your Name], Personal Representative." The court-appointed executor or administrator is usually the signer. If there are co-representatives, the bank may require more than one person to appear, sign, or complete identity checks.

Sunset can help gather documents, search for assets, prepare probate packets, coordinate an FDIC-insured estate account, and support transfers and distributions. The estate does not pay Sunset, and assets go to the beneficiaries and heirs.
