Definition
A law clerk is a legally trained assistant who supports a judge, justice, or other judicial officer in the preparation and analysis of legal matters. In modern American practice, law clerks are typically recent law school graduates—often among the top of their class—who serve one- or two-year appointments with a federal or state judge. Their work includes researching legal questions, analyzing briefs, drafting bench memoranda, and assisting in the preparation of judicial opinions. Some courts also employ career law clerks (sometimes called staff attorneys or permanent clerks) who serve in that capacity indefinitely rather than for a fixed post-graduation term.
The term carries a second, historically significant meaning: in English and early American practice, a law clerk was a person serving in a solicitor's or attorney's office for a prescribed period as a condition of admission to the bar. Under that usage, the clerkship was a formal apprenticeship—closer to what American lawyers today would call "reading law."
Common Language
Modern common usage (Wiktionary): A clerk who assists a judge with legal proceedings. Depending on the court, such positions may be professional careers or may be temporary positions for graduating law students.
Historical common usage (Webster's 1913): Not separately defined; "clerk" generally denoted a person employed to keep records or accounts, or one trained in a clerical or scholarly occupation.
The gap matters for researchers consulting historical sources. In older legal literature and dictionaries, "law clerk" almost always refers to the apprentice-in-an-attorney's-office meaning, not the judicial assistant meaning. A researcher encountering the term in a nineteenth-century English treatise or an early American bar admission record should not assume the modern judicial-assistant sense applies.
Common Confusion
Law clerk is sometimes conflated with court clerk (also called clerk of court). These are distinct roles. The clerk of court is an administrative officer of the court responsible for maintaining dockets, filing documents, and managing court records—a position that may require no legal training. A law clerk is a legally trained aide to the judge personally. In large federal courts, both may be present simultaneously and perform entirely different functions.
The term is also occasionally confused with paralegal or legal assistant, which are support roles within law firms rather than judicial offices.
Recognized Forms
/SUBTYPES
Elbow clerk: Informal term for a law clerk who works in close, daily collaboration with a single judge (as opposed to a pool or central staff arrangement).
Staff attorney/career clerk: A permanent judicial employee performing clerk-like functions, typically in appellate courts that process high volumes of cases. Distinguished from the traditional term-limited clerkship.
Appellate clerk vs. trial court clerk: Clerkships at the appellate level (including the U.S. Supreme Court) involve primarily written analysis; trial court clerkships may include courtroom observation and procedural support.
Why It Matters in Research
Researchers working in the Law Mind corpus face two distinct traps with this term.
First, the temporal shift in meaning. Bouvier and other nineteenth-century dictionaries define the law clerk as an apprentice attorney—a person in training, not a judicial aide. If you are researching bar admission history, legal education, or the structure of the early American legal profession, the Bouvier definition is the operative one. If you are researching the modern federal judiciary or judicial opinion-writing practices, the modern judicial-assistant definition controls. Mixing sources from different eras without accounting for this shift will produce confused results.
Second, jurisdictional and institutional variation in the modern sense. Federal clerkships (particularly at the circuit and Supreme Court level) carry significant prestige and have a well-documented selection culture. State court clerkships vary enormously—some states have robust clerkship programs; others have minimal or no equivalent. Research on judicial clerkships as an institution should be anchored to the specific court and time period rather than treated as a uniform phenomenon.
For researchers interested in the English antecedent (the articled clerk system), Bouvier's cross-reference to ARTICLED CLERK is the correct entry point. The English system of articled clerkship was a formal, regulated apprenticeship under a solicitor and has no direct modern American equivalent—though it is the conceptual ancestor of "reading law" bar admission pathways that persist in a small number of U.S. jurisdictions.
Historical Dictionary Support
Bouvier's Law Dictionary defines the law clerk as "a person serving a certain period in the office of a practising attorney or solicitor, in order to qualify himself to practice as an attorney or solicitor," citing Burrill and directing readers to ARTICLED CLERK. This definition reflects the English and early American understanding of the term as a stage of professional formation rather than a judicial role. Bouvier makes no reference to the judicial-assistant function that now dominates American usage—an absence that itself marks how completely the dominant meaning of the term has shifted since the nineteenth century.
The judicial clerkship as an American institution emerged in the late nineteenth century, with Justice Horace Gray of the Massachusetts Supreme Judicial Court credited with establishing an early model of the practice before joining the U.S. Supreme Court. The institution grew through the twentieth century and is now a standard feature of the federal judiciary. Historical legal dictionaries predate this development entirely and are therefore unreliable guides to the modern sense of the term.
Jurisdictional Note
In the United States, federal judicial clerkships are governed by individual courts and judges, with no single statutory framework. State clerkship practices vary significantly: some states mirror federal practice closely; others use different titles, longer terms, or centralized hiring processes. The historical English meaning (articled clerk serving a solicitor) reflects a formal regulatory system that has no current American equivalent, though England and Wales retain a modified version of supervised legal training through the solicitor qualification pathway.
