Letters Testamentary vs Letters of Administration: What's the Difference

Two Documents, One Purpose

To administer a probate estate — such as closing probate accounts, paying debts, or distributing probate assets — you generally need authority from the court. That authority may be evidenced by a court-issued document, and the document usually depends on whether the deceased left a valid will. Non-probate assets may pass under beneficiary designations or title rules.

Letters testamentary are issued when the deceased left a valid will that names an executor. The court reviews the will, confirms its validity, and issues the letters to the named executor, officially authorizing them to manage the estate.

Letters of administration are issued when there is no valid will (the person died "intestate"). If a named executor is unable or unwilling to serve, the court follows the procedure provided by local law, which may use a different form of appointment. The court appoints an administrator — typically a close relative who petitions for the role — and issues letters authorizing them to administer the estate.

The practical difference matters less than people think. Both documents evidence court authority to administer an estate, but the representative's powers can depend on the will, court orders, and local law. The distinction is generally about how the representative was appointed.

How to Get Letters Testamentary

If you're named as executor in a valid will, the process is relatively straightforward:

1. Locate the original will. Courts require the original signed document, not a copy. Check the deceased's home, safe deposit box, and attorney's office.
2. File a petition for probate with the surrogate's court or probate court in the county where the deceased resided. You'll need the original will, a certified death certificate, and a list of all known heirs and beneficiaries.
3. Check notice and waiting requirements. They depend on the jurisdiction and court. One New Jersey example has a 10-day waiting period; do not assume that timing applies elsewhere.
4. Attend the hearing. In uncontested cases, this is typically brief and procedural. The judge confirms the will's validity, accepts your oath as executor, and issues the letters.
5. Receive your letters testamentary. Ask each bank, brokerage, or government agency what form and number of copies it requires.

Filing fees vary by county and estate value. Some courts charge a base filing fee of $50–$200 or more; asset-based fees may range from $100–$500. Check the local court's fee schedule.

How to Get Letters of Administration

Without a will, local law determines who may administer the estate and how the court selects that person. A surviving spouse, adult children, parents, siblings, or more distant relatives may have priority depending on the jurisdiction. Check the local rules before petitioning for appointment:

1. File a petition for letters of administration with the probate court. You'll need a certified death certificate, proof of your relationship to the deceased, and a list of all known heirs.
2. Ask whether a bond is required. Courts may require an administrator to post a surety bond, but the requirement and amount depend on local law and the court.
3. Attend the hearing and receive appointment. The process is similar to the testamentary path but may involve more scrutiny, especially if multiple relatives compete for the appointment.

The administration path can take longer or cost more when the court requires a bond or when family members dispute who should serve.

What the Letters Actually Let You Do

Once you hold either document, you become the estate's legal representative. Practically, this means:

• Open an estate bank account using the estate's EIN (obtained free from the IRS via Form SS-4 online)
• Ask about access to the deceased's financial accounts — a bank may require the letters plus a certified death certificate to release funds from a probate account
• Collect debts owed to the deceased — outstanding invoices, tax refunds, insurance payouts
• Pay the estate's obligations — final medical bills, credit card balances, mortgage, utilities
• Sell real and personal property as needed to settle the estate
• File the deceased's final tax return and any estate tax returns
• Distribute remaining assets to heirs or beneficiaries

Without these letters, you generally lack authority to administer the probate estate, and institutions may restrict access to estate accounts. The letters are evidence of the court's appointment and authority.

When Things Get Complicated

Several common scenarios create friction:

The named executor doesn't want to serve. Ask the probate court how to decline; the required notice or filing depends on local procedure. The will may name an alternate executor; otherwise, the court follows local law to appoint someone to administer the estate.

Multiple people petition for administration. When siblings or other relatives disagree about who should serve, the court holds a hearing to determine the most suitable administrator. Priority generally follows the intestacy statute, but courts have discretion to consider factors like geographic proximity, financial competence, and conflicts of interest.

You're an unmarried partner. Intestacy priority lists generally do not include unmarried partners unless local law recognizes the relationship as a marriage or other eligible status. Ask a local probate attorney whether you can petition for appointment or otherwise protect an interest in the estate.

The will is contested. If someone challenges the will's validity (alleging lack of capacity, undue influence, or forgery), the challenge can affect when letters testamentary are issued. Ask the probate court whether a temporary representative can be appointed to handle urgent matters.
