How to Open an Estate Account: Requirements, Steps, and Common Mistakes

Why You Need a Separate Estate Account

The moment you start handling someone else's money as executor, you have a legal obligation to keep it separate from your own. Commingling estate funds with personal funds — even temporarily — is one of the fastest ways to face personal liability and beneficiary lawsuits.

An estate bank account is where all estate income flows in (rent from the deceased's property, dividends, insurance proceeds) and all estate expenses flow out (funeral costs, debts, taxes, distributions). Every transaction gets documented, which you'll need for the final accounting to the court or beneficiaries, as required in your jurisdiction.

What You Need Before the Bank

For a formal probate estate, you generally need court-issued authority before opening an estate account. Bank and tax-ID requirements depend on the institution and jurisdiction:

1. Get Letters Testamentary (or Letters of Administration)

The court must formally appoint you as executor. This document — letters testamentary if there's a will, letters of administration if there isn't — is your legal credential. Banks commonly ask for court-issued proof of your authority, though their requirements differ.

Timeline: two to six weeks from filing the probate petition, assuming no one contests the will.

2. Obtain an Employer Identification Number (EIN) in the United States

For a US estate, an EIN is generally used for estate tax reporting and is commonly requested when opening an estate account. Apply online at irs.gov — the process takes about 10 minutes, and you receive the EIN immediately.

You'll need the decedent's Social Security number and your own SSN as the responsible party. The EIN is free. Don't pay a third-party service to file for you.

In Canada, you'll need a trust account number from the CRA. In the UK, you apply through HMRC's trusts and estates service. In Australia, contact the ATO for a tax file number for the estate.

3. Get Certified Copies of the Death Certificate

Ask the bank whether it requires a certified copy or accepts another form of proof. Have any required certified copies available for the bank and other institutions.

The Bank Visit: Step by Step

Choose the bank. You can open the estate account at any bank — it doesn't have to be where the deceased banked. Some executors choose a bank they already use for convenience. Others choose the deceased's bank to simplify account closures and fund transfers.

Bring the required documents:

• Letters testamentary or letters of administration (ask the bank what form of copy it accepts and whether it sets an issue-date limit)
• The estate's EIN confirmation
• A certified death certificate
• Your government-issued photo ID
• The will (some banks want to see it, though most don't require it)

Open a basic checking account. Choose an interest-bearing account if the estate will hold significant funds, since the executor has a fiduciary duty to protect and grow estate assets. Avoid accounts with high minimum balance requirements or monthly fees that would unnecessarily drain the estate.

Set up the account title correctly. The account should be titled "Estate of [Deceased's Full Legal Name], [Your Name] as Executor" (or Administrator). Do not title it in your personal name.

Common Mistakes That Delay the Process

Bringing the wrong copy of letters testamentary. Ask the bank whether it needs a certified copy with the court seal and whether it sets an issue-date limit.

Forgetting the EIN. You cannot open an estate account with the deceased's Social Security number. The estate needs its own tax identification.

Trying to open the account before probate is granted. Until the court issues letters testamentary, you generally lack authority to act for the estate. Some executors try to use the will itself as proof of authority, but banks commonly require court-issued proof.

Using a personal account as a temporary holding account. Even with the best intentions, routing estate funds through a personal account creates legal exposure and audit complications. Wait until you can open the proper estate account.

What About Frozen Accounts?

When a bank learns of an account holder's death (often through Social Security notifications or a family member's visit), it freezes the account. The funds are still there — they're just inaccessible until someone with legal authority (the executor with letters testamentary) presents the required documentation.

This freeze can create cash-flow problems in the first weeks. Funeral expenses, mortgage payments, and utility bills don't pause for probate. Some executors advance these costs personally and reimburse themselves from the estate account once it's open.

If the deceased had jointly held accounts with right of survivorship, the surviving owner retains full access — those accounts don't freeze. Only individually held accounts are affected.

After the Account Is Open

Once the estate account is active:

• Transfer funds from the deceased's individual accounts as you close them
• Deposit insurance proceeds, tax refunds, and other estate income
• Pay legitimate estate expenses — debts, taxes, administration costs
• Keep meticulous records of every transaction, with receipts attached
