Definition
Res furtivæ (also rendered res furtive) is a Latin legal term meaning stolen goods — specifically, property that has been taken by theft and thereby tainted by that criminal act. The term was used in Scots law to denote the character that stolen property acquired upon the commission of the theft: the goods themselves became legally marked by the wrong, carrying consequences for anyone who subsequently handled, purchased, or possessed them regardless of their knowledge of the theft.
The concept reflects a broader principle that theft attaches a kind of legal stigma or encumbrance to the thing itself, not merely to the thief. Under this doctrine, the original owner's title was not extinguished by the theft; the res furtivæ remained the owner's property in law, and the thief (and, in some formulations, subsequent possessors) could not pass good title to another.

Common Confusion
Res furtivæ is occasionally confused with related Latin property terms — particularly bona vacantia (ownerless goods) or res derelictæ (abandoned property) — because all three involve goods whose ordinary possession or ownership is disrupted. The confusion is consequential: bona vacantia and res derelictæ concern property without an owner, while res furtivæ concerns property whose rightful owner retains title precisely because the dispossession was unlawful. The policy directions are opposite. Do not conflate res furtivæ with the Roman law rule nemo dat quod non habet, though the two work in tandem: res furtivæ explains the status of the goods; nemo dat explains why a thief cannot convey good title from them.

Why It Matters in Research
Res furtivæ is primarily a term of Scots law and Roman-influenced civilian legal systems, not English common law. Researchers working in English common law sources will rarely encounter the Latin phrase; its conceptual work is done instead by the common law rules on larceny, receiving stolen goods, and the limitations on bona fide purchaser protection for personal property. This jurisdictional split is the most important navigational fact about the term.
In the Law Mind corpus, res furtivæ will surface almost exclusively in historical sources touching Scots law, comparative law discussions, or treatises drawing on Roman law foundations. Bell's Dictionary of the Law of Scotland is the primary cited authority in every historical legal dictionary entry on this term, and researchers should trace the concept there rather than through English or American common law digests.
For researchers tracing the trajectory of the idea into modern law: the core principle — that theft does not transfer title, and that stolen goods carry a defect that follows them — has robust modern expression in the law of bona fide purchasers, the Uniform Commercial Code's treatment of voidable versus void title, and criminal receiving statutes. Those modern sources will not use the Latin phrase, but the doctrine travels under different names.
Trap for historical researchers: the phrase appears in clusters in historical dictionaries immediately before or after res gestæ entries, because both begin with "res g-/f-" in alphabetical runs. Scanning dictionary pages for res gestæ (a far more commonly cited term) risks skipping or misreading a nearby res furtivæ entry. The two terms are entirely unrelated in substance.

Historical Dictionary Support
Black's Law Dictionary, Rapalje & Lawrence, and Burrill's Law Dictionary are in complete agreement on this term: all three define res furtivæ as stolen goods under Scots law, and all three cite Bell's Dictionary of the Law of Scotland as the sole or primary authority. This uniform sourcing reflects the term's narrow jurisdictional home rather than any genuine triangulation across sources — the dictionaries are essentially copying the same reference.
What the historical dictionaries do not address is the doctrinal content behind the label: the consequences of a thing being res furtivæ, the rules about subsequent possession, or the relationship to Roman law usucaption (the Roman rule that stolen things could not be acquired by long possession — usucapio furtivorum — which is the deeper source of the Scots doctrine). Researchers wanting the substantive doctrine rather than just the definition will need to go beyond these dictionary entries to Bell directly or to comparative treatments of Roman and Scots property law.
The dictionaries also do not distinguish between the singular form (res furtiva, a stolen thing) and the plural (res furtivæ, stolen things/stolen goods), though both forms appear in historical sources.

Jurisdictional Note
Res furtivæ is a term of Scots law and Roman-civilian tradition. It does not appear as a term of art in English common law or American law. The underlying principle — that theft does not transfer title — is recognized in both common law and civilian systems, but common law systems express it through different vocabulary and doctrinal frameworks. Researchers should not assume that finding the term in a general legal dictionary means it was operative in English or American courts.
