Definition
A Latin maxim meaning "to the whole" or "to the original or former state." Used in legal contexts to describe the restoration of a party to the position they occupied before a transaction, injury, or legal proceeding altered their circumstances. The phrase most commonly appears in connection with rescission, restitution, and equitable relief — situations where a court orders or a party seeks a return to the status quo ante rather than merely monetary compensation for loss.
The full phrase most often encountered in doctrine is restitutio in integrum — restoration in full, or restoration to the original position — of which in integrum is the operative directional component. Standing alone, in integrum functions as a modifier signifying completeness and wholeness of restoration, as opposed to partial or compensatory relief.

Common Language
Modern common usage (Wiktionary): Not a standard entry. The phrase has no recognized common English usage outside legal and academic contexts.
Historical common usage (Webster's 1913): Not listed. The term remained confined to Latin legal and ecclesiastical writing throughout the period Webster's covered.
This section is omitted because in integrum has no meaningful common English counterpart. It is pure legal Latin with no double meaning risk from ordinary usage.

Common Confusion
In integrum is frequently encountered as a fragment of restitutio in integrum and should not be treated as interchangeable with it. In integrum describes the destination or condition aimed at (the original, whole state); restitutio in integrum names the legal remedy or doctrine that achieves it. Researchers encountering in integrum in historical texts may also confuse it with in statu quo (in the existing state) — a superficially similar concept that points in the opposite direction. In statu quo preserves the current position; in integrum reverses to the prior one.

Why It Matters in Research
The phrase appears almost exclusively as part of a longer Latin formula in primary sources. Researchers searching Law Mind's corpus for in integrum alone will miss the bulk of relevant material, which is indexed under restitutio in integrum, restitution, and rescission. Run searches on all three.
In equity treatises and early common law reports, in integrum signals that the court is entertaining full rescission rather than partial adjustment — a distinction with significant procedural consequences, particularly regarding whether a party seeking relief must tender back what they received before the court will act. Historical sources through the nineteenth century use this phrase in contract cases involving fraud, duress, and mistake, and in maritime and civil law contexts.
The phrase carries heavier freight in civil law jurisdictions, where restitutio in integrum had a formal procedural identity as a specific type of relief available from the praetor in Roman law. Common law sources absorbed the concept but not always the terminology with precision. Researchers working across civil law and common law materials will find the same underlying idea labeled differently: civil law texts use in integrum or restitutio in integrum; common law texts may say "put the parties back in their original position" or "restore the status quo ante" without the Latin. This divergence can cause researchers to underestimate how widely the doctrine traveled.
In international arbitration and treaty law materials, in integrum appears in discussions of state responsibility and remedies — specifically the principle that a state that has wrongfully injured another must restore the situation that would have existed had the wrongful act not occurred. Researchers in public international law should connect this phrase to the broader framework of full reparation.

Historical Dictionary Support
All three source dictionaries agree on the core definition — "to the original or former state" — and all trace the phrase to Calvinus's Lexicon Juridicum, the standard Renaissance-era authority on Latin legal terminology. There is no divergence among the sources on meaning.
Burrill's adds the Digest references (Dig. 4.1 and 4.6), which locate the phrase in the Roman law titles governing restitutio in integrum — specifically the praetorian edict's grant of relief to parties who suffered legal prejudice through minority, fraud, absence, or fear. This is the most useful additional information the historical dictionaries provide: the Roman procedural context establishes that in integrum was never a vague aspiration but a technically defined standard of relief. Burrill also cross-references integer, the root adjective meaning whole, untouched, or unimpaired, which illuminates why the phrase connotes completeness rather than mere approximation.
What the historical dictionaries miss is the phrase's migration into equity doctrine and international law, where it does significant work in nineteenth- and twentieth-century sources well after the classical Roman procedural framework was abandoned.

Jurisdictional Note
The concept behind in integrum operates in all common law jurisdictions through the doctrine of rescission and restitution, but the Latin phrase itself appears far more frequently in Scottish, South African, and civil law-influenced Commonwealth jurisdictions, where Roman law terminology retained formal currency longer than in English or American courts.
