Letters of Administration: The No-Will Path to Estate Authority
Letters of administration are the court document that proves you have legal authority to act for the estate of someone who died without a will. They do the same job as letters testamentary, except the court, not a will, chose the person in charge. Banks and county offices will not release the deceased person’s accounts until you show them.

The Short Answer
When a person dies without a valid will, no one is named to run the estate. So the probate court appoints an administrator, usually a close relative, and issues letters of administration as proof of that appointment. That document is what a bank asks for before it will let you access, move, or close the deceased person’s accounts.
The same document goes by different names depending on the state and the situation. If there had been a will naming an executor, the court would issue letters testamentary instead. Same authority, different route to the job.
Administration vs. Testamentary
The two names answer one question: how was the person in charge chosen?
- Letters of administration go to an administrator the court selects when there is no will, or the named executor has died, declined, or been removed.
- Letters testamentary go to the executor a valid will names. The will speaks; the court confirms.
Either way the holder is the estate’s personal representative, with a fiduciary duty to gather assets, pay valid debts in order, and distribute what is left. When there is no will, the people who inherit are set by your state’s intestate succession law, not by the administrator’s choice.
Who the Court Appoints
With no will to nominate anyone, state law sets a priority order for who may serve as administrator. It commonly runs in this order, though the exact list and any residency rules vary by state:
- The surviving spouse
- Adult children of the deceased person
- Parents, then siblings
- Other heirs, and finally a creditor or a public administrator if no one else will serve
A person with higher priority can decline and nominate someone else. If two people with equal priority both want to serve, the court decides. Your state guide lists the exact order and who is eligible.
How to Get Them
The path mirrors an executor’s, with one added step because no will names you:
- File a petition to open probate with the county court where the person lived, stating there is no will.
- Provide a certified death certificate, a list of the heirs, and notice to the people the law requires.
- Ask the court to appoint you as administrator under the state priority order.
- Take the oath, and post a probate bond if the court requires one, which is common with no will to waive it.
- The court issues your letters of administration. Order several certified copies at once.
The free probate assessment can tell you whether a formal appointment is even needed, since many small estates pass by a small estate affidavit with no letters issued at all.
What Your State Calls Them
The document is nearly universal; the name is not. Open your state’s guide for the exact form, court, and steps:
Letters of Administration (no will, or no named executor who can serve)
Letters of Appointment (the term used in Arizona)
A Michigan letter of authority and a Florida letter of administration prove the same thing: this person may act for the estate.
What They Unlock
Once you hold letters, most of the administrator’s real work becomes possible:
- Get the estate’s federal tax ID (EIN) and open the estate bank account.
- Access, consolidate, and close the deceased person’s financial accounts.
- Sort assets into what does and does not pass through court (see probate vs. non-probate assets).
- Deal with creditors and pay debts in the required order, then distribute what remains to the legal heirs.
Keep the certified copies current. When an institution rejects one for being too old, the court can issue a fresh certified copy on request. For a question specific to your appointment, a probate attorney is the right call.
