Letters Testamentary: What They Are and How to Get Them

A plain-English guide to letters testamentary — what they prove, how an executor obtains them, typical timelines, what banks require, and how they differ from letters of administration.
If you've been named executor of an estate, you'll likely hear the phrase "letters testamentary" fairly early in the process — often from a bank, a probate clerk, or an attorney. It's an unfamiliar term to most people who haven't served as an executor before, but the concept behind it is simple.
What Are Letters Testamentary?
Letters testamentary are a document issued by the probate court that formally confirms you have legal authority to act as executor of a specific estate. Despite the plural "letters," it's typically a single certified document (sometimes several certified copies).
Think of it as your official proof, similar to how a driver's license proves you're licensed to drive. Without it, banks, brokerages, and government agencies generally won't let you access or manage the deceased person's assets, even if you're clearly named as executor in the will.
How Do You Get Letters Testamentary?
The general process, which varies by state and county:
- File the will and a probate petition with the probate court in the county where the deceased person lived.
- Provide the death certificate and notify heirs/beneficiaries as required by your state.
- Attend a hearing or complete required waiting periods, if your state requires one (some allow this to happen without a hearing if there's no dispute).
- The court reviews the will and confirms you're the named executor (or appoints you if there's no objection).
- The court issues letters testamentary, often along with a requirement to post a bond, depending on state law and the will's instructions.
Typical Timeline
Timelines vary considerably by county caseload and whether the estate is contested, but as a general pattern:
- Simple, uncontested estates may receive letters testamentary within a few weeks of filing.
- More complex or contested situations can take a few months before letters are issued.
- Some states offer expedited or simplified procedures for small estates, which can shorten this considerably.
Check with your local probate court clerk for realistic timelines in your county — they can vary significantly even within the same state.
What Banks and Institutions Typically Need
When you present letters testamentary to a bank, brokerage, or other institution, they will typically also ask for:
- A certified copy of the letters testamentary (get several extra copies from the court — most families need 3-10 depending on the number of accounts and institutions involved)
- A certified death certificate
- Your government-issued ID
- The estate's EIN (employer identification number) if you're opening an estate bank account
Because certified copies often have a per-copy fee, it's worth estimating up front how many accounts, insurance policies, and institutions you'll need to contact, and requesting that many copies (plus a couple extra) at the courthouse in one trip.
Letters Testamentary vs. Letters of Administration
These two documents serve the same basic purpose — proving legal authority over an estate — but apply in different situations:
| Letters Testamentary | Letters of Administration | |
|---|---|---|
| When issued | There is a valid will naming an executor | There is no will, or the will didn't name a valid executor |
| Who receives them | The executor named in the will | An "administrator" appointed by the court, often a close relative |
| Authority granted | Generally the same — to manage and settle the estate | Generally the same — to manage and settle the estate |
Functionally, once issued, both documents grant similar authority. The difference is mainly in the legal basis (a will vs. state intestacy law) and the title used for the person managing the estate.

Do You Always Need Letters Testamentary?
Not always. Many states offer simplified procedures for small estates below a certain value threshold, which may let you skip formal probate — and letters testamentary — entirely, using an affidavit process instead. Whether this applies depends on the size and type of assets in the estate and your state's specific threshold, so it's worth checking with the local probate court or an attorney before assuming you need full letters testamentary.
Common Questions Executors Run Into
- What if I lose my certified copy? You can typically request additional certified copies from the same probate court for a fee.
- Do letters testamentary expire? Some states place time limits or require reconfirmation for older letters, particularly for real estate transactions — check with the issuing court if it's been a long time since issuance.
- Can more than one person hold letters testamentary? Yes, if the will names co-executors, the court can issue letters testamentary to both, and both signatures may be required for certain transactions.
Key Takeaway
Letters testamentary are the practical key that unlocks your ability to act as executor — without them, most institutions will not release funds or information to you, regardless of what the will says. Requesting enough certified copies at the outset, and understanding your state's specific process and timeline, will save you a good deal of back-and-forth later in the estate settlement.
