Definition
Letters of administration are the formal written authorization issued by a probate court, surrogate's court, or other court of competent jurisdiction, appointing a person—called an administrator or administratrix—to manage and settle the estate of a person who has died. The document confers legal authority on the administrator to collect assets, pay debts and claims, and distribute the estate's property to those entitled by law.
Letters of administration are issued in two principal circumstances: (1) when the decedent died intestate—that is, without a valid will—and therefore left no named executor to manage the estate; or (2) when the decedent left a will but that will failed to name an executor, or the named executor is unwilling or unable to serve. In the latter situation, the issuing court appoints an administrator to carry out functions similar to those of an executor.
The letters themselves are a document of authority, not merely a record. A third party—a bank, title company, or government agency—presented with letters of administration can rely on them as evidence that the holder has lawful power to act on behalf of the estate. Without them, an administrator has no recognized legal standing to transfer title, access accounts, or bind the estate.

Common Language
Wiktionary: Plural of "letter of administration."
The word "letter" in ordinary modern English suggests a piece of correspondence. Here it functions in the older formal sense—an official written instrument conferring authority, closer to "letters patent" or "letters of marque" than to a personal communication. A researcher encountering the term for the first time may underestimate its weight: letters of administration are not correspondence but a court-issued credential. The plural form is standard even when referring to a single instrument.

Common Confusion
Letters of administration are frequently confused with letters testamentary. Both are court-issued instruments authorizing someone to administer a decedent's estate, and both are often called simply "letters" in practice. The distinction is functional: letters testamentary are issued when a valid will exists and names an executor who is willing and qualified to serve; letters of administration are issued when no valid will exists, or when the will names no functioning executor. An administrator appointed by letters of administration generally occupies the same practical role as an executor appointed by letters testamentary, but the legal source of authority differs—one flows from intestacy or will deficiency, the other from testamentary appointment confirmed by the court.

Recognized Forms
/SUBTYPES
Letters of administration with the will annexed (also called cum testamento annexo, or c.t.a.): Issued when the decedent left a valid will but named no executor, or the named executor cannot or will not serve. The administrator must follow the terms of the will while deriving authority from the court, not from testamentary appointment.
Letters of administration de bonis non (d.b.n.): Issued to administer the remaining assets of an estate after an original administrator (or executor) has died, resigned, or been removed before completing administration. "De bonis non" refers to the goods not yet administered.
Letters of administration d.b.n.c.t.a.: A combination of the above, issued when there is a will, the original administrator died or was removed, and assets remain unadministered.
Temporary or special letters of administration: Some jurisdictions issue these on an emergency basis to preserve estate assets while formal appointment proceedings are pending.

Why It Matters in Research
Researchers working in probate, estate, or succession law must track several fault lines this term presents.
Terminology drift. Historical sources—including many nineteenth-century cases and the standard historical dictionaries—use "letters of administration" only in the intestacy or failed-executor context. Modern practice in many jurisdictions has broadened the umbrella term, sometimes using it loosely to refer to any court-issued administrator authorization. Reading older sources requires care: a historical case discussing the scope of letters of administration may not address the c.t.a. variant at all.
Intestate versus testate context. Because letters of administration historically presupposed intestacy, a researcher tracing the administrator's duties or liabilities through historical case law should verify whether the case involves a pure intestacy, a c.t.a. situation, or a d.b.n. appointment. The rules governing priority of appointment, the scope of authority, and the administrator's bond obligations can vary across these situations.
Jurisdiction-specific nomenclature. Probate procedure is almost entirely state-law governed in the United States. The court that issues letters of administration may be called a probate court, surrogate's court, orphans' court, or chancery court depending on jurisdiction. The procedural steps, required bond, and priority list for who may be appointed administrator vary significantly. Letters of administration issued in one state do not automatically authorize action in another; ancillary administration may be required where the decedent held property in multiple states.
Third-party reliance. In transactional research—title searches, estate litigation, banking disputes—understanding what letters of administration authorize is critical. Their validity can be challenged if the issuing court lacked jurisdiction, if the administrator was disqualified, or if the letters were issued based on a false representation of intestacy while a will actually existed.

Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in close agreement on the core definition: both describe letters of administration as the instrument issued by the surrogate or probate court authorizing an administrator to manage the goods and chattels of a decedent. Burrill adds the important clarification that the instrument issues not only in intestacy but also when a will exists "without appointing an executor"—a distinction Black's omits, though it does address the c.t.a. form as a separate entry elsewhere.
Both sources reflect a historical emphasis on personal property ("goods and chattels"), consistent with the English common law tradition in which administration primarily concerned movables. Neither source adequately accounts for the modern administrator's role in managing real property, digital assets, or complex financial instruments—areas where contemporary probate practice has moved well beyond the historical definitions.
The historical focus on the surrogate as the issuing officer is accurate for the English tradition and for states that retained surrogate's court nomenclature (notably New York and New Jersey), but it does not capture the full range of issuing courts in American jurisdictions.

Jurisdictional Note
Letters of administration are governed entirely by state law in the United States, and procedural requirements—including who may petition for appointment, what priority rules apply among potential administrators, bond requirements, and the form of the instrument itself—vary considerably across jurisdictions. Researchers should not treat any single state's scheme as representative. In England and Wales, the equivalent function is now carried out under the Non-Contentious Probate Rules, with a grant of letters of administration issued by the Probate Registry; the term and its underlying framework remain in active use there.
