What these documents actually are
Proof of authority, not a title to inherit
Letters Testamentary (when there's a will naming an executor) or Letters of Administration (when there isn't, and the court appoints an administrator instead) are documents issued by a probate court. They prove to banks, insurers, and other institutions that a specific person is legally authorized to act on behalf of the estate – collecting assets, paying debts, and eventually distributing what's left. They don't, by themselves, say who inherits what; that's determined by the will or by state intestacy law.
Executor vs. administrator
An executor is named in a valid will. An administrator is appointed by the court when there's no will, no executor named, or the named executor can't or won't serve – usually the surviving spouse or an adult child, following an order of priority set by state law. Practically, the two roles work the same way once appointed.
How the process generally works
File a petition with the probate court
The person seeking to be appointed (usually the executor named in the will, or the closest heir if there's no will) files a petition with the probate court in the county where the deceased lived, along with the death certificate and the original will, if there is one.
Notify heirs and, often, creditors
Most states require formal notice to heirs and beneficiaries, and many require a public notice to creditors – giving them a window (commonly a few months) to file claims against the estate before it can be closed.
Receive the Letters and start administering the estate
Once the court approves the petition, it issues the Letters Testamentary or Letters of Administration – typically a one-page certified document. From here, the executor or administrator opens an estate bank account, collects assets, pays valid debts and taxes, and eventually distributes what remains according to the will or state law.
Timelines vary a lot
A simple, uncontested estate might close in a few months; a larger or contested one can take well over a year. If the estate is small, many states offer a much faster alternative.
Who typically asks to see it
Once you have your Letters, expect these organizations to ask for a certified copy (alongside the death certificate) before releasing information or closing an account.
-

To access, close, or transfer individually-owned accounts not covered by a beneficiary designation. -
Life insurers
Usually only if there's no named beneficiary, in which case the policy proceeds go to the estate instead. -
The IRS
When filing the final individual return or an estate tax return on the deceased's behalf. -
County recorder / DMV
For transferring real estate or vehicle titles out of the deceased's name.
Common questions about Letters Testamentary
What's the difference between Letters Testamentary and Letters of Administration?
Letters Testamentary are issued when there's a valid will naming an executor. Letters of Administration are issued when there's no will (or no named executor available), and the probate court instead appoints an administrator under state intestacy law. Both documents serve the same practical purpose: proving to banks and institutions that you're authorized to act for the estate.
How long does probate usually take?
It varies enormously by state and by how complicated the estate is – anywhere from a few weeks for a simple, uncontested small estate to well over a year for a larger or contested one. Many states also require creditors to have a window (often several months) to file claims before the estate can be closed.
Do I always need Letters Testamentary to access a deceased person's accounts?
No. Assets that are jointly owned, have a named beneficiary (like life insurance or a payable-on-death account), or are held in a living trust generally pass outside of probate. And many states let smaller estates skip full probate using a small estate affidavit instead.
Can I apply for Letters Testamentary myself, without an attorney?
In many states, yes – especially for simple, uncontested estates, and some probate courts have self-help resources for exactly this. Whether it's advisable depends on the size and complexity of the estate, and whether other heirs might contest the will; a probate attorney can tell you whether your situation is straightforward enough to handle yourself.
