Definition
A Law French verb meaning to bar out, preclude, or deprive permanently. In old English law, forbarrer described the act of cutting off a person's legal right or claim entirely — rendering it unenforceable going forward. The term functioned as a conceptual predecessor to estoppel and bar, expressing the idea that a party could be foreclosed from asserting a right, typically by operation of statute or judicial proceeding. Where forbarrer appears in historical sources, it signals a permanent legal exclusion rather than a temporary procedural obstacle.
Common Language
This is pure legal jargon of Law French origin with no meaningful counterpart in ordinary modern or historical English usage. The COMMON LANGUAGE section is omitted.
Common Confusion
Forbarrer, estoppel, and bar are related but not identical. Forbarrer is the archaic Law French verb; bar and estoppel are the English doctrinal successors that absorbed its function. In historical sources, forbarrer may appear where a modern reader would expect the noun "bar" or the phrase "estopped from." Researchers should not treat the terms as technically interchangeable across periods — forbarrer is the older form and carries a stronger connotation of permanent, often statutory, deprivation rather than the procedural or equitable nuances that later attached to estoppel.
Why It Matters in Research
Structural pattern: historical evolution. Forbarrer is essentially a fossil term — it appears in pre-modern English legal texts and statutes but did not survive into modern practice as a living term. Its significance for researchers is almost entirely navigational and interpretive.
The primary trap is anachronistic reading. When forbarrer appears in a medieval or early modern source, it does not map cleanly onto any single modern doctrine. Depending on context, it may point toward what we now call res judicata, collateral estoppel, statutory bar, or common-law estoppel. Researchers should examine the surrounding procedural context carefully before assigning a modern doctrinal equivalent.
Burrill's entry is the most useful in the corpus because it anchors the term to specific historical statutes — Statute of Gloucester (c. 3), 9 Ric. II c. 2, and 6 Hen. VI c. 4 — giving researchers specific legislative sources to consult when the term appears in connection with real property or inheritance disputes. The related form forbarres (past tense: barred, stopped) appears in Britton (c. 119) and Littleton (§ 640), meaning researchers working with those primary sources will encounter the conjugated form, not just the infinitive.
The proximity of forbarrer to forbatudo/forbatudus (a related Law Latin term, noted at the end of Burrill's entry) suggests a cluster of related medieval terminology around the concept of forcible exclusion or defeat of a legal claim. Researchers encountering either term should consider whether both appear in the same source document, as they sometimes traveled together in glossaries and treatises.
Historical Dictionary Support
Black's (both editions) treats forbarrer minimally — a brief two-part gloss: "to bar out; to preclude; hence, to estop." The compression is accurate but thin, offering no statutory grounding and no guidance on the range of contexts in which the term appeared.
Burrill's is substantially richer and the preferred reference for historical research. It identifies forbarrer as belonging to old English law specifically, supplies the conjugated form forbarres with a citation to Britton and Littleton, and connects the term to named statutes. The phrase "to bar or deprive forever" in Burrill is notable — the adverb "forever" captures the permanence that distinguishes forbarrer from mere procedural delay or dismissal. This nuance is absent from Black's and matters when interpreting the severity of the legal consequence described in a source document.
No historical dictionary in the corpus connects forbarrer explicitly to equity doctrine, which reflects the term's age: it predates the mature equity jurisdiction that would later give rise to equitable estoppel as a distinct body of doctrine.
Jurisdictional Note
Forbarrer is historical and English in origin. It does not appear as a living term in any modern common law jurisdiction. Researchers working in American legal history may encounter it in early colonial sources that drew on English precedent, but it carries no distinct American doctrinal development.
