Definition
A person who speaks or acts on behalf of another in a legal proceeding. In legal usage, an advocate is one who assists, advises, and pleads the cause of a client before a court or tribunal. The term encompasses the full range of representative functions: giving legal advice, preparing arguments, and presenting them orally before a decision-making body.
In civil law and Scottish practice, "advocate" carries a more precise technical meaning, equivalent to what common law systems call a barrister — a legally trained professional admitted to practice who appears in court on behalf of clients. In Scots law, the Faculty of Advocates is the corporate body of the Edinburgh bar, a specific institution with formal membership requirements.
In United States practice, the term has no technical distinction from "attorney" or "counsel" and is used broadly and interchangeably. Any licensed attorney appearing on behalf of a client functions as an advocate.
Common Language
Modern common usage (Wiktionary): An advocate is someone who argues the case of another — either in a formal legal proceeding or more broadly as a supporter of a cause or person, including non-legal contexts such as disability advocacy or public policy.
Historical common usage (Webster's 1913): One who pleads the cause of another before a tribunal; also, one who espouses any cause by argument, as in "an advocate of free trade." Webster's also notes the theological usage: Christ as intercessor, drawn from 1 John ii. 1.
The gap between common and legal meaning is real but moderate. Everyday use has extended "advocate" into non-legal support roles — a patient advocate, a housing advocate — where no legal representation is involved. In legal research, the word's appearance in a document does not guarantee a licensed attorney is meant. Context, jurisdiction, and era determine whether "advocate" refers to a specific professional role or a general function.
Common Confusion
ADVOCATE vs. ATTORNEY vs. COUNSEL vs. BARRISTER: In U.S. sources, these terms are largely synonymous and courts use them interchangeably. In English and Commonwealth sources, the distinction matters: a barrister advocates in court while a solicitor advises and prepares cases, but typically does not argue them. "Counsel" often signals the advocacy function specifically, while "attorney" emphasizes the agency relationship. Researchers working across jurisdictions must not assume the U.S. equivalence holds in British, Scottish, or civil law materials.
Recognized Forms
/SUBTYPES
Devil's advocate: A formal role in Catholic canonical proceedings — a church official appointed to argue against the canonization of a candidate for sainthood. The term has passed into general use to mean anyone who argues a contrary position for the sake of argument.
Judge Advocate: A military legal officer. Anderson's directs readers to this term, reflecting its distinct institutional meaning in military law.
Taxpayer Advocate: In U.S. federal tax administration, a statutory officer within the IRS charged with assisting taxpayers in resolving disputes with the agency. A specific modern usage of "advocate" as an institutional title rather than a description of courtroom function.
Why It Matters in Research
The term's instability across jurisdictions and time periods creates real navigation challenges. Three traps to watch for:
First, civil law and common law sources use the word differently. In French, Spanish, or Scottish legal materials, "advocate" (or its cognate) names a specific professional class with defined qualifications and court privileges. Importing that meaning into U.S. sources — or vice versa — produces errors.
Second, the historical dictionaries reflect a period when English law formally distinguished advocates from attorneys and solicitors. Burrill, Bouvier, and both editions of Black's define advocate in terms that echo civil law tradition. Anderson explicitly notes that in the United States this distinction collapsed. A researcher reading an 18th or early 19th century English treatise that refers to "advocates" should not assume the author means what an American attorney does today.
Third, the modern proliferation of non-legal advocacy roles — patient advocates, disability advocates, consumer advocates — means the word in a contemporary document may carry no legal content at all. When researching agency relationships, professional responsibility, or unauthorized practice questions, confirm that "advocate" in the source refers to licensed legal representation.
The Taxpayer Advocate Service entry in the Law Mind Tax Encyclopedia illustrates how the term has been institutionalized in a specific administrative context, worth consulting when research involves IRS dispute resolution.
Historical Dictionary Support
The historical dictionaries converge on the core definition — a person learned in the law who assists and pleads for another — with only modest variation. Burrill and both editions of Black's are nearly identical, both drawing on Holthouse. Bouvier is the most historically minded, tracing the Latin root advocatus and noting that in classical usage the word could mean an assistant or helper of any kind, including an accomplice in crime. That range of the original Latin term is a useful reminder that the word's legal precision is a product of centuries of narrowing.
Anderson's is the most practically useful for U.S. researchers: it makes explicit that American practice collapses the distinction between advocate and attorney, and it cross-references Judge-Advocate for military law purposes.
What the historical dictionaries miss: none of them anticipate the administrative and non-legal senses of "advocate" that dominate contemporary usage outside the courtroom. They also predate the formal statutory creation of advocate offices within administrative agencies — a development that gave the term new institutional meanings in the 20th century.
Jurisdictional Note
The distinction between advocate and attorney is functionally significant in Scotland, England, and civil law jurisdictions, where advocacy and solicitation remain formally separated professions. In all U.S. jurisdictions, no such distinction exists — any licensed attorney may both advise and argue in court. Researchers moving between common law and civil law sources, or between American and British materials, should treat the term as jurisdiction-specific until context confirms otherwise.
