Letters Testamentary and Letters of Administration are both court orders that hand someone legal authority over a deceased person’s estate. Neither document changes who inherits what.
They simply prove to the outside world, banks, title companies, the IRS, that a specific person has the court’s permission to act on the estate’s behalf.
The person named in letters testamentary is called the executor or personal representative. The person named in letters of administration is called the administrator.
In many states the two roles are collectively described as “personal representative,” so do not be surprised if a form uses that broader term instead.
Without one of these documents, an heir generally cannot close a bank account, sell a house, or file a final tax return for the deceased. That is why probate courts treat issuing letters as a priority step early in the process.
The Core Difference: Was There a Valid Will?
The entire distinction comes down to one question: did the deceased leave a valid Will that names an executor?
If yes, the court issues letters testamentary. If no, or if the Will is silent on who should serve, the court issues letters of administration instead.
This single fact, present Will or absent Will, determines almost everything downstream: how the person in charge is chosen, how much court supervision they face, and which set of rules governs how the assets get divided.
How Someone Becomes an Executor Under Letters Testamentary
An executor is nominated by the deceased, in writing, inside the Will itself. The probate court’s job is to confirm the Will is valid, confirm the nominated person is willing and legally able to serve, and then issue letters testamentary.
Because the deceased chose this person directly, courts generally give executors more independence than administrators receive. The Will can also grant extra powers, such as the ability to sell real estate without a separate court order, that an administrator would not automatically have.
To apply, the nominated executor typically files the original Will and a death certificate with the probate court in the county where the deceased lived, then attends a short hearing where a judge confirms the appointment.
How Someone Becomes an Administrator Under Letters of Administration
When there is no Will, state intestate succession law decides who gets first priority to serve as administrator. That priority order is usually the surviving spouse first, then adult children, then parents, then siblings, and so on down the family tree.
Because no one chose this person in advance, courts tend to supervise administrators more closely than executors. An administrator often must file a bond, post regular accountings with the court, and get judicial approval before selling property.
The process for applying is similar to letters testamentary in paperwork terms, a petition, a death certificate, notice to heirs, but it also usually requires proving who the legal heirs are, since there is no Will to identify them.

Frequently Asked Questions
How long does it take to get letters testamentary or letters of administration?
Timing depends on the county court’s caseload, but many petitioners receive their letters within a few weeks to two months after filing a complete petition.
Can an administrator be a family member if there is no Will?
Yes. State law sets a priority order, typically starting with the surviving spouse, then children, then parents, then more distant relatives.
Is a bond required for letters testamentary or letters of administration?
Administrators are more commonly required to post a bond. Wills often waive the bond requirement for the named executor, though courts can still require one in some circumstances.
Can letters of administration be issued if a Will exists?
Yes, if the Will fails to name an executor, the named executor cannot serve, or the Will is found invalid, the court issues letters of administration instead of letters testamentary.
Do banks accept letters testamentary and letters of administration the same way?
Generally yes. Both are court issued proof of authority, and most banks and title companies treat them the same for purposes of releasing funds or transferring property.
What happens if there is a dispute over who should be the administrator?
The probate court resolves the dispute, usually by applying the state’s statutory priority order and holding a hearing if multiple qualified relatives are competing for the role.
