What Are Letters Testamentary, and Why Do Banks Ask for Them?

Many first-time executors discover this the hard way. They have the will, they have the death certificate, and the bank still says no. The missing piece is a document called letters testamentary - and understanding it early can save weeks of frustration.

What are letters testamentary?

Letters testamentary are an official document issued by a probate court that certifies a person’s authority to act as executor of an estate. They’re proof to everyone else - banks, brokers, insurers, title companies, government agencies - that the court has appointed you and that they can safely deal with you. California’s court system describes its version of the form as what a person appointed as personal representative uses to prove to others that the court has officially appointed them.

Despite the name, “letters” is a single court document, not correspondence.

Why can’t I just show the will and a death certificate?

Because being named executor in a will doesn’t, by itself, give you legal authority. The court has to admit the will to probate and formally appoint you first. Texas provides a clear example. After the court signs the order admitting the will and appointing the executor, the executor has 20 days to complete “qualification”: filing an oath, posting a bond if one is required, and, for an executor who lives outside Texas, appointing a local agent. Only on or after the qualification date can the executor receive letters testamentary from the probate clerk.

Once you have them, a Texas probate court’s executor guide says, banks, brokers, title companies, insurance companies, and government agencies will require letters to authorize you to handle assets. Institutions have good reason: they can’t hand an estate’s money to someone just because the person says they’re the executor.

How do you get letters testamentary?

The general path is the same everywhere, but the forms and details differ by state:

1. File with the probate court in the county where the person lived, usually an application or petition to admit the will and appoint the executor
2. The court admits the will and appoints you, sometimes after a hearing
3. Complete any qualification steps, such as an oath and, where required, a bond
4. The clerk issues the letters, and you can order certified copies

Some state examples, from court sources:

• Texas: letters are issued by the probate clerk on or after your qualification date. The Tarrant County guide says to contact the clerk directly for current fees for letters and certified copies. See our guide on how probate works in Texas.
• California: the court issues a single Judicial Council form, DE-150, “Letters,” to the appointed personal representative. See how probate works in California.
• Ohio: the term is different. The Supreme Court of Ohio’s statewide probate forms include an “Application for Authority to Administer Estate” and an “Entry Appointing Fiduciary; Letter of Authority,” plus a separate “Application to Probate Will.” See how probate works in Ohio.

What’s the difference between letters testamentary and letters of administration?

Letters testamentary go to an executor named in a valid will. Letters of administration go to an administrator the court appoints when there is no will or no named executor available. The practical purpose is the same: proof of authority. When there’s no will, the estate is distributed under the state’s intestacy law instead of the will; see our guide on what happens if you die without a will.

Terminology varies. Some states call the representative a “personal representative” whether or not there’s a will, and Ohio calls the document a “letter of authority.” If you’re unsure which applies, ask the probate clerk in the county where the person lived.

What do banks and other institutions actually ask for?

Expect them to want a certified copy, not a photocopy. A few details from the Texas guide are worth knowing:

• Some institutions will only accept letters that have been certified within the past 60 days, so you may need to order new certified copies as the estate stays open
• Some third parties also want a certified copy of the will
• You’ll still need a death certificate; see our guide on getting death certificates

Because so many institutions each want their own certified copy, executors commonly order several up front rather than going back repeatedly. Ask the clerk what copies cost, and keep a simple list of which institution holds which copy.

What can you do with letters testamentary?

They let you act for the estate: collect its assets, deal with banks and brokerages, pay debts, and eventually distribute what’s left to beneficiaries. You act as a fiduciary, which means you owe a duty to treat beneficiaries and creditors fairly. The Texas guide, for example, tells independent executors to keep estate funds in a separate designated account rather than mixing them with their own money.

Letters don’t give you unlimited power. In Texas, for instance, your authority to sell estate real property should be addressed in the will; if it isn’t, your attorney must ask the court for permission. See our guides on executor responsibilities and handling debts after a death.

For the limits on that authority, see what an executor can’t do.

What do the letters set in motion?

Getting letters starts a clock. The Texas guide shows how this can work: within roughly one to two months the executor must publish a notice to creditors and notify secured creditors, within 60 days of the will’s admission must send formal notice to beneficiaries, and within 90 days of qualification must file a sworn inventory of the estate. Failing to file the inventory on time can lead to removal and a fine of up to $1,000, according to the guide. Other states have different deadlines, so ask the court or an attorney what applies to you.

Do you always need letters?

No. Many assets pass outside probate, for example accounts with a named beneficiary, jointly owned property with survivorship rights, and assets held in a trust, and those typically don’t require letters. Smaller estates may qualify for a simplified process instead. Ohio’s court forms, for example, include an “Application to Relieve Estate From Administration” and a “Summary Release From Administration.” Other states have their own small-estate options.

See our guide on probate vs. non-probate assets, and our state small-estate guides such as Texas, California, and Ohio. If a bank asks for letters on a small account, it’s reasonable to ask whether it accepts a small-estate affidavit instead.

How long do letters take, and do I need a lawyer?

Timing depends on the court, how busy it is, and whether anyone contests the will, so there’s no reliable single answer. Ask the probate clerk what to expect.

On lawyers, the rules differ by state. The Tarrant County guide states that in Texas an independent executor must be represented by a licensed Texas attorney throughout the process. Other courts handle this differently, and complicated estates benefit from legal advice regardless. See our guides on estate attorney cost and how much probate costs.

What if you’re the one writing the will?

Naming an executor, and a backup, and telling them where your will and key documents are, spares your family the first and hardest week. Note who should serve in your Final Day Plan.
