Definition
Latitatio (Latin: a lying hid; lurking) was a term in civil law and old English practice referring to the deliberate concealment of a person's whereabouts to evade legal process. Where a defendant could not be found for service of process because they were hiding or secreting themselves within the jurisdiction, that conduct constituted latitatio. The condition was legally significant because it triggered alternative modes of process and, in some proceedings, could be treated as a form of contempt or contumacy. It is distinct from simple absence or flight from the jurisdiction — latitatio implied the person was present but hiding, typically within the county or district.
In old English practice, the writ of latitat was the procedural instrument built directly on this concept: it recited that the defendant "lurks and wanders" (latitat et discurrit) in the county, providing the legal fiction that justified issuing a King's Bench capias where the defendant could not be found to answer a bill of Middlesex. The latitatio concept thus underpinned an entire strand of English process architecture before its statutory abolition.
Common Confusion
Latitatio is sometimes loosely equated with flight or absconsion. The distinction matters: flight typically implies departure from the jurisdiction, whereas latitatio specifically described concealment within the jurisdiction. A person who had fled abroad was not latitating in the technical sense; the writ and the doctrine presupposed the person was present but evading service. Researchers should also avoid conflating latitatio with contumacia (contumacy) — both could arise from a defendant's refusal to appear, but contumacy was the legal characterization of defiance of process, while latitatio described the physical fact of hiding that preceded or prompted that characterization.
Why It Matters in Research
Latitatio is primarily a term of historical legal architecture rather than living doctrine. Its research significance is almost entirely backward-looking.
The term is the conceptual root of the writ of latitat, one of the principal original writs of the Court of King's Bench. Researchers tracing the history of English personal jurisdiction, mesne process, or the competition between common law courts will encounter latitatio as the fiction that allowed King's Bench to expand its reach. Bracton's treatment (fol. 126) and the Digest passage (42.4.7.5) are the foundational sources; researchers working in Roman-derived civil law traditions should check whether the civilian concept carried different procedural consequences than the English common law adaptation.
The entire latitat framework was abolished by the Civil Procedure Act 1833 (St. 2 Will. IV, c. 39), which rationalized English process. After that date, the term disappears from operative English procedure. Researchers working in post-1833 sources will encounter it only in historical commentary or in common law jurisdictions that retained pre-reform process structures longer than England did.
For corpus researchers: the term surfaces in plea rolls, Year Books, and early treatise literature. Because it is a Latin term of art, variant spellings and abbreviated forms appear in manuscript sources. Burrill's note that latitatio derives from the verb latitare (to lurk, to hide habitually — itself a frequentative of latere, to be hidden) is useful for identifying related word forms in search strings across historical sources.
Historical Dictionary Support
The three source dictionaries are in close agreement, which is itself informative: latitatio had a settled, narrow meaning that did not evolve or generate doctrinal controversy in the way more contested terms did. All three sources track the same two authorities — Digest 42.4.7.5 and Bracton fol. 126 — indicating that the term's lineage from Roman civil law into English practice was well understood and not disputed.
Black's first edition adds the critical procedural payoff: the note linking latitatio to Blackstone's Commentaries (3 Bl. Comm. 286) and the abolishing statute. This connection, absent from Burrill, situates the term within the machinery of the writ of latitat and gives researchers the exit point for the doctrine's historical use. The second edition of Black's reproduces the core definition faithfully but does not add the procedural note, suggesting the editors treated the civil law definition as the primary entry and the English practice application as supplementary.
What the historical dictionaries do not address: the civilian tradition's treatment of latitatio in contexts beyond debt enforcement (the Digest passage concerns judgment debtors), or any American reception of the concept. American common law practice generally adopted English process forms but the latitat writ had limited transplantation; researchers should not assume American colonial or early republic sources will use the term in the same way.
Jurisdictional Note
Latitatio as operative doctrine is English and civilian; it has no modern jurisdictional home. In jurisdictions that inherited English common law process, the abolition of the latitat writ in 1833 effectively retired the term from active use. Civil law jurisdictions may retain analogous concepts for evasion of process by concealment, but under different terminology.
