Do Executors Need Letters Testamentary in Michigan

If you've been named as an executor in Michigan and the deceased had bank accounts, you're probably wondering whether you need letters testamentary before you can do anything with those funds. This is one of the most common and most frustrating questions executors face early in the probate process. Without the right documents, banks will turn you away. With them, doors open. Understanding how this works can save you weeks of delays and protect you from legal trouble down the road.

What Are Letters Testamentary and Why Do Banks Care?

Letters testamentary are a court-issued document that proves you have legal authority to act on behalf of a deceased person's estate. Think of them as your official credential. When a bank sees these letters, it knows the probate court has approved you to handle the decedent's financial affairs.

Banks don't take your word for it. They won't accept a will alone, and they won't accept a death certificate by itself. They need proof that a Michigan probate court has formally appointed you. That's what letters testamentary provide legal confirmation that you are the rightful executor with power over estate assets.

Without these documents, banks have no way to verify that you're authorized. If they released funds to the wrong person, they'd face serious liability. So they follow a strict policy: no letters, no access.

Do Michigan Executors Always Need Letters Testamentary to Access Bank Accounts?

In most cases, yes. If the deceased person held bank accounts solely in their name with no beneficiary designation, the executor almost certainly needs letters testamentary to access those accounts. This applies to checking accounts, savings accounts, CDs, and safe deposit boxes held only in the decedent's name.

However, there are exceptions worth knowing about. Some accounts bypass the probate process entirely, which means you may not need letters testamentary for every financial asset. These include:

Accounts with a payable-on-death (POD) designation These pass directly to the named beneficiary without probate.
Joint accounts with rights of survivorship The surviving account holder typically takes full ownership automatically.
Accounts with a transfer-on-death (TOD) beneficiary Similar to POD, these transfer outside of probate.
Trust-held accounts If the account was owned by a trust, the successor trustee handles it, not the executor.

For accounts that don't fall into these categories, letters testamentary are your key. You can learn more about when an executor might have authority without letters testamentary, but the general rule holds: banks want to see those court-issued letters before they let you touch the money.

How Does the Process of Getting Letters Testamentary Work in Michigan?

To get letters testamentary, you'll need to file the will (if one exists) with the probate court in the county where the deceased lived. You'll submit a petition asking the court to formally appoint you as executor. After a hearing or review depending on the county's procedures the court issues the letters.

The timeline varies. Some counties move faster than others, but you should expect the process to take at least a few weeks. During that waiting period, you cannot access the decedent's sole-ownership bank accounts. This is one of the biggest practical challenges new executors face there may be bills to pay, but no legal access to funds yet.

What Happens When You Bring Letters Testamentary to the Bank?

Once you have letters testamentary in hand, bring them along with a certified copy of the death certificate and your government-issued ID to the bank. The bank will review the documents and may ask you to fill out internal paperwork.

After verification, the bank will typically:

Allow you to open an estate checking account to hold the decedent's funds.
Transfer funds from the decedent's individual accounts into the estate account.
Grant you access to any safe deposit boxes held in the decedent's name.
Provide account statements and transaction history for the estate records.

Each bank has its own internal process, so expect some variation. Some banks are quicker; others require multiple visits. Bring more documentation than you think you'll need it's better to be overprepared than to make a second trip.

Once you have access, your responsibilities expand significantly. Our article on what executors need to do after letters testamentary are issued covers the full range of duties that follow.

Can a Bank Refuse to Accept Your Letters Testamentary?

It happens more often than you'd expect. Banks may push back if the letters are old, if the document has errors, or if the bank questions whether the account in question actually requires probate. Some banks have stricter internal policies than others.

Common reasons a bank might hesitate:

The letters don't name the executor clearly or contain a typo.
The bank suspects the account had a POD or joint ownership feature that bypasses probate.
The letters were issued in a different state and the bank wants Michigan-specific court documentation.
The executor's identification doesn't match what's on file.

If you run into resistance, ask the bank to put their objection in writing. That gives you something specific to address, whether through your attorney or the probate court.

What Are the Most Common Mistakes Executors Make With Bank Access?

New executors often stumble in predictable ways. Here are the mistakes that cause the most problems:

Trying to access accounts before getting letters testamentary. Even if you're named in the will, that's not enough. Banks need the court-issued letters.
Assuming a death certificate is sufficient. It proves the person died. It does not prove you have authority to act.
Using estate funds for personal expenses. The estate account is not your money. Commingling funds is a serious breach of fiduciary duty.
Failing to get enough certified copies. You'll need certified copies of both the letters and the death certificate for multiple banks, insurance companies, and agencies.
Not understanding the difference between letters testamentary and letters of administration. These are different documents issued under different circumstances. If the decedent died without a will, you'd receive letters of administration instead of letters testamentary, and the court process changes accordingly.

Do You Need a Lawyer to Get Letters Testamentary in Michigan?

Michigan law doesn't require you to hire an attorney, but it's strongly recommended especially if the estate has significant assets, debts, or potential disputes among heirs. The probate process involves court filings, legal notices, and fiduciary obligations that can be hard to manage without guidance.

Attorneys who practice Michigan probate law can handle the filing, communicate with banks on your behalf, and help you avoid errors that could delay the process or expose you to personal liability. The cost is usually paid from estate funds, not your own pocket.

If you want to understand more about the legal framework, the Michigan Estates and Protected Individuals Code (MCL 700.3601) outlines executor powers and when they become effective.
