Definition
De droit is a Law French phrase meaning "of right" or "by right." It appears in medieval and early modern English legal texts to signal that a claim, title, or action rests on an absolute right — a right of full entitlement — rather than on mere possession or procedural advantage. The phrase derives from the Law Latin equivalent *de jure* and carries the same core meaning: grounded in law and rightful title, not merely in fact or custom.
In practice, *de droit* most commonly surfaces in the names or descriptions of common law writs and possessory actions, where it distinguished actions asserting a full title from those asserting only seisin or possession. The classic opposition is between a *dreit* action (going to the right itself) and a possessory action (going only to who most recently held possession). Courts and commentators of the period understood this as a hierarchical distinction: an action *de droit* was the stronger, more difficult, and more conclusive form of claim.

Common Confusion
De droit (*of right*) is frequently encountered alongside *de facto* (*of fact*) in historical sources, and researchers sometimes treat the two as a simple binary opposition. They are not strict antonyms. *De droit* contrasts most precisely with *de facto* in the sense that *de jure* does — lawful title versus actual possession or exercise — but *de droit* is a term of art from the older common law writ system, while *de facto* has survived as living legal vocabulary. Do not assume that every *de facto*/*de jure* passage in a modern source maps cleanly onto the older *de droit* framework; the modern pairing carries different doctrinal freight.

Why It Matters in Research
Researchers encounter *de droit* almost exclusively in pre-modern English legal materials: Year Books, Bracton, Britton, Fitzherbert's *Natura Brevium*, and the Register of Original Writs. The term is a marker of the medieval writ system's internal architecture, particularly the distinction between real actions that went to the *right* (such as the writ of right itself) and possessory assizes (such as *novel disseisin*) that went only to recent seisin.
Several research traps are worth noting:
First, *de droit* does not appear in modern statutory or case law as an operative term. If you encounter it in a source after the mid-nineteenth century, you are almost certainly reading a historical treatment or a quotation from an older authority.
Second, the phrase is embedded in the names of obsolete writs and actions — including the broader *breve de recto* (writ of right) family — and may appear as a qualifier in those writ names without being separately indexed. Search for it in context, not in isolation.
Third, the *de droit / de facto* distinction matters when researching the historical roots of modern doctrines that retain the *de jure* versus *de facto* vocabulary — corporate formation, parentage, government authority — because the conceptual lineage runs through this older Law French usage. Understanding what *de droit* meant in the writ system illuminates why the *de jure* / *de facto* binary retains the shape it does in modern doctrine.
Finally, be alert to the fact that Burrill's entry for *de droit* is brief and transitions immediately into adjacent writ entries (*de ejectione custodiae*, *de ejectione firmae*). This is a common organizational feature of historical law dictionaries: short bridge entries that serve primarily as cross-references within the writ taxonomy. Do not mistake brevity for insignificance; the concept anchors a large portion of the real action system.

Historical Dictionary Support
Burrill's Law Dictionary gives *de droit* a compact entry: "L. Fr. [L. Lat. *de jure*.] Of right," with a citation to Britton, chapter 107. This entry is representative of how historical legal dictionaries handled Law French bridge terms — they confirm the equivalence to Latin and gesture toward authority without elaborating on doctrinal application. The citation to Britton is apt; Britton is one of the primary thirteenth-century treatises that organized English law in Law French and used *de droit* to describe actions going to full title.
What Burrill does not do — and what no single dictionary entry does well for this term — is explain the structural role *de droit* played in the hierarchy of real actions. For that, researchers must go to the treatise literature: Bracton's *De Legibus et Consuetudinibus Angliae*, Britton, and Fitzherbert's *Natura Brevium* collectively provide the framework within which *de droit* was a technical term of art. Blackstone's *Commentaries* (Book III, on private wrongs) provides the most accessible later synthesis of this action hierarchy for a modern reader.

Jurisdictional Note
*De droit* is a term of English common law provenance and has no meaningful independent life in American, Scottish, or civil law systems. In American legal history, the writ system that gave *de droit* its operative meaning was abolished well before the Field Code reforms of the mid-nineteenth century. Researchers in American jurisdictions will encounter the term only in historical materials or in scholarship tracing doctrinal genealogy.

Encyclopedia Cross-Reference
The concept of right versus fact — the substantive core of *de droit* — connects to several living doctrines treated in the Law Mind Encyclopedia:
- *Corporate Formation — Defective Incorporation (De Facto, Corporation by Estoppel)* (The Law Mind Business Organizations & Corporate Law Encyclopedia): The *de jure* / *de facto* corporation distinction is the modern corporate law descendant of the same right-versus-fact framework.
- *Paternity — De Facto Parent and Psychological Parent Doctrines* (The Law Mind Family Law Encyclopedia): The *de facto* parent doctrine applies the same structural logic — recognized status despite absence of formal legal right — in family law.
- *Standards of Review on Appeal (De Novo, Abuse of Discretion, Plain Error)* (The Law Mind Criminal Law Encyclopedia): *De novo* review, meaning review "as of right" or "anew," carries the *de jure* lineage into appellate procedure.
