Definition
A Latin verb from old English law meaning "to keep" or "to guard." In legal usage, *custodire* denotes the act of keeping, maintaining, or exercising custody over a thing — whether fire, property, livestock, or another object capable of causing harm or requiring safeguard. The term appears most characteristically in pleading and case law addressing liability for negligent keeping, where a party's failure to properly *custodire* a dangerous thing formed the basis of a legal wrong.

Why It Matters in Research
Researchers encountering *custodire* in old English legal texts are most likely working with early common law materials — Year Books, early case reports, or Latin pleadings — where the word functions as the operative verb of custody or keeping in a negligence or trespass context. The phrase recorded in Burrill — *tam negligenter et improvide custodivit ignem suum, quod domus combusta fuit* ("so negligently and carelessly kept his fire, that the house was burnt") — illustrates how *custodire* anchored the duty element in early fire-spread cases. These cases are precursors to what later common law would organize under negligence, nuisance, and the rule in *Rylands v. Fletcher*.
Two traps exist for the researcher. First, the term will not appear in modern legal databases in its Latin form except in historical materials or scholarly commentary on early common law. Searching for *custodire* or *custodivit* requires access to Latin-language legal sources, Year Book digests, or early reporters like Coke's Reports. Second, the term's root connects it to a large family of English legal derivatives — *custody*, *custodian*, *custodia legis* — but these derivative terms carry their own independent doctrinal histories and should not be read back into the Latin original without care.
The citation in Burrill (5 Co. 14) refers to Coke's Reports, a primary source for this kind of early common law Latin usage. Researchers tracing the development of keeper liability or the duty of care for dangerous instrumentalities should treat this term as a signpost into pre-modern negligence doctrine rather than a free-standing legal concept with ongoing doctrinal force.

Historical Dictionary Support
Burrill's Law Dictionary provides the only entry among the shelf sources. The definition is spare — "to keep" — and illustrates the term through a single Latin phrase drawn from Coke's Reports. Burrill presents *custodire* in a strictly descriptive mode, identifying it as old English law usage without attempting to connect it forward to contemporary doctrine.
The quoted phrase is instructive precisely because it shows how *custodire* was embedded in a standard pleading formula for fire cases: the adverbs *negligenter* and *improvide* (negligently and improvidently) modify the verb, establishing that the legal wrong was not the mere act of keeping fire but the manner of keeping. This structure — keeper + manner of keeping + resulting harm — reflects the early common law logic that would eventually be rationalized under negligence principles. Burrill does not develop this connection, and no other standard historical legal dictionary in the Law Mind corpus includes a discrete entry for *custodire*.
