Definition
A Latin term meaning "to hold," "to keep back," or "to detain." In legal usage, detinere is the root verb underlying several technical forms that appeared in pleading, particularly in actions of replevin and detinue. The inflected forms carried precise procedural meanings:
- Detinet ("he withholds"): The form used in a plaintiff's declaration to allege that the defendant was currently withholding property to which the plaintiff had a right of possession.
- Detinuit ("he withheld" or "has withheld"): The form used to allege past wrongful detention, typically where the property had already been returned before the action was fully resolved but the plaintiff still sought damages for the period of unlawful withholding.
- Non detinet ("he does not withhold"): The defendant's pleading form denying that any wrongful detention existed.
These were not loose descriptive terms but formal words of art. Their presence or absence in a writ or declaration determined the procedural posture of the action and, in replevin, directly controlled what remedies were available.
Common Confusion
Detinere, detinet, and detinuit are closely related but procedurally distinct. Detinet placed before the court a present, ongoing wrong — the goods had not been returned and the plaintiff wanted them back. Detinuit acknowledged that the goods had been returned but preserved the plaintiff's claim for damages arising from the wrongful detention. Conflating the two in historical sources means misreading both the stage of the litigation and the remedy the plaintiff was actually seeking. Researchers working with early common law pleading records must distinguish which form appears in the record to understand what was actually in dispute.
Why It Matters in Research
Detinere and its inflected forms are primarily encountered in historical legal sources. They appear in treatises on common law pleading, in Year Books, in early English court records, and in American legal sources from the colonial period through the nineteenth century, when formal pleading under the common law forms of action remained in use. After the procedural reforms of the mid-to-late nineteenth century — the Field Code in New York (1848) and similar code pleading reforms elsewhere, followed by the Federal Rules of Civil Procedure (1938) — these Latin pleading forms fell out of active use. Modern sources rarely employ them.
Researchers working in the Law Mind corpus should expect to encounter these terms when reading:
- Historical treatments of replevin and detinue as forms of action
- Treatises on common law pleading from Blackstone forward through nineteenth-century American commentators
- Court records and opinions from jurisdictions that retained formal pleading longer than others
A key trap: the distinction between detinet and detinuit matters for understanding what a historical court was actually resolving. A detinuit count was not merely a stylistic variant — it signaled that the property dispute itself had effectively concluded and what remained was an accounting for damages. Reading these forms as interchangeable will produce a distorted picture of the litigation.
Corpus connections run directly to detinue and replevin, the two actions in which these forms were most prominent, as well as to trover and conversion for comparison with overlapping remedies for interference with personal property.
Historical Dictionary Support
Anderson's Dictionary of Law provides the core entry: detinere as the Latin verb "to hold, keep back, detain," with detinet, detinuit, and non detinet identified as technical pleading words in replevin actions describing the claim of illegal detention and its denial. The entry is compact but accurate.
Anderson captures the essential structure — that these are inflected forms of a single Latin verb deployed in formally distinct procedural roles — though without elaboration on the procedural consequences of choosing one form over the other. Historical treatises on common law pleading, such as those of Chitty and Stephen, provide richer accounts of how these forms functioned in practice and why a plaintiff's election between detinet and detinuit carried real strategic and remedial significance. What Anderson does not address, and what historical dictionaries generally underemphasize, is that detinere and its forms were already archaic in American legal practice well before the twentieth century, surviving primarily in treatise literature and historical commentary rather than in live pleading.
Jurisdictional Note
The detinet/detinuit distinction was a feature of common law pleading as it developed in England and was received into American colonial and early state practice. Jurisdictions that abolished the forms of action earlier — through code pleading reforms — moved away from this terminology sooner. In English legal sources, the terminology persisted longer and may appear in nineteenth-century cases and treatises with more regularity than in American counterparts of the same period.
