Definition
Coram vobis (Latin: "before you") is a writ of error directed to a court other than the one now reviewing the case — most commonly from a higher court back to the trial court that entered the judgment — commanding that court to correct an error of fact in its own record. The writ operates as a procedural mechanism for reopening a final judgment where the error is factual, not legal: a fact unknown to the court at the time of judgment that, had it been known, would have changed the outcome.
Coram vobis is the mirror image of coram nobis. Where coram nobis ("before us") is a writ a court directs to itself to correct its own factual errors, coram vobis is directed by one court to another — specifically, by a reviewing court downward to the court that originally tried the cause. In English practice, coram vobis was the form used when the reviewing court (such as the King's Bench) identified a factual error in the judgment of an inferior court (such as the Common Pleas) and returned the matter there for correction.
The writ does not reach errors of law. Its province is the narrow category of facts — typically relating to the legal capacity of a party, defects in process, or supervening circumstances — that were not apparent on the face of the record and could not have been raised by ordinary appeal.

Common Confusion
CORAM VOBIS vs. CORAM NOBIS: These two writs are frequently conflated, and in modern American usage the distinction has largely collapsed. The Latin signals the difference: coram nobis ("before us") is self-directed — the court addresses its own error. Coram vobis ("before you") is directed outward, from a reviewing court to the court below. In contemporary American practice, coram nobis has become the generic term for both functions. Researchers encountering coram vobis in historical sources should not assume the modern coram nobis doctrine controls; the procedural posture and the issuing court matter.
CORAM VOBIS vs. WRIT OF ERROR: A writ of error and a writ of error coram vobis both originate from a superior court directed toward a lower tribunal, but they serve distinct purposes. A standard writ of error addresses mistakes of law apparent on the record. Coram vobis reaches only errors of fact not apparent on the record. Conflating the two in historical research produces false results.

Why It Matters in Research
Researchers working in pre-twentieth-century common law sources will encounter coram vobis as a live procedural writ with its own distinct identity. Several navigational points are essential:
The writ is jurisdictionally specific in historical sources. Burrill's entry ties it particularly to the Court of Common Pleas in English practice, distinguishing it from coram nobis, which belonged to the King's Bench. When reading English reports or treatises before the Judicature Acts of the 1870s, the court of origin determines which form applies. Importing either term carelessly across court lines produces anachronism.
In American state practice, coram vobis survived in some jurisdictions well into the twentieth century as a distinct writ, while others folded it into coram nobis or abolished it by rule. Federal courts effectively eliminated both writs in 1946 when the Federal Rules of Civil Procedure (Rule 60(b)) superseded common law extraordinary relief mechanisms in civil cases. The Federal Rules of Criminal Procedure (Rule 35) similarly reorganized post-judgment relief in criminal matters. Researchers examining federal cases after 1946 will rarely find coram vobis as a live procedural vehicle, but may find the writ discussed historically or in contexts where Rule 60(b) is inadequate.
The distinction between fact and law errors is critical and often contested in the corpus. A court denying a coram vobis petition frequently did so on the ground that the claimed error was legal, not factual. Reading these denials requires understanding where courts drew that line at the relevant time and place — a line that shifted across jurisdictions and centuries.
Corpus connections: entries touching extraordinary writs, post-conviction relief, writs of error, and the King's Bench / Common Pleas jurisdictional split will all intersect with coram vobis. The coram nobis entry is the essential companion.

Historical Dictionary Support
The three source dictionaries agree on the core function — a writ of error correcting factual error, directed to the court that tried the cause — but differ usefully in emphasis.
Black's defines the writ as directed "by a court of review to the court which tried the cause," keeping the focus on the reviewing court's role and the downward direction of the writ. Bouvier's, by contrast, pivots quickly to coram nobis, treating coram vobis as the inverse case: where coram nobis corrects errors in the King's Bench on its own record, coram vobis handles the same function for inferior courts. Bouvier's framing is technically accurate but risks underselling the independent significance of coram vobis as a writ in its own right.
Burrill's is the most practically granular of the three, tying the writ specifically to the Common Pleas and citing Tidd's Practice for the procedural mechanics — a useful pointer for researchers needing to trace the historical doctrine into English procedural law. The Tidd citation (2 Tidd's Pr. 1137, 1142, 1143) refers to William Tidd's The Practice of the Courts of King's Bench and Common Pleas, a standard English procedural treatise of the early nineteenth century.
All three dictionaries share the same Maryland Reports citation (3 Md. 325), which serves as their common American authority. None of the entries addresses the writ's fate under modern procedural reforms — an expected gap given their publication dates, but one that matters enormously for corpus researchers whose sources span the pre- and post-rules eras.

Jurisdictional Note
In English practice, coram vobis attached specifically to courts other than the King's Bench, most prominently the Common Pleas. American jurisdictions adopted the writ unevenly; some states retained it in name or substance after federal procedural reforms, while federal courts effectively replaced it through Rule 60(b) in civil matters. Researchers should verify whether a given jurisdiction had abolished or merged the writ before treating historical coram vobis doctrine as controlling.
