ANIMUS REVERTENDI

Definition

Animus revertendi (Latin: "intention of returning") is a legal concept operating in two distinct but related contexts: 1. DOMICILE: The intention to return to a place after a temporary absence. A person does not lose their domicile merely by departing from it, provided they retain animus revertendi — that is, a genuine intent to return. The departure must be coupled with an intent to abandon the place permanently before domicile is lost. Temporary absences, however extended, do not destroy domicile when this intent to return persists. 2. PROPERTY IN ANIMALS (Civil Law Origin): The rule governing ownership of domesticated or tamed wild animals (ferae naturae that have been reclaimed). So long as such animals retain the habit of returning — and the owner can demonstrate the animal's disposition to come back — ownership continues. Once the animal loses the habit or inclination to return, ownership ceases and the animal may be taken by another as res nullius. The civil law maxim captures this directly: ownership persists only as long as the animal retains animus revertendi; when that disposition is gone, the animal becomes the property of whoever takes it.

Common Confusion

The two applications of animus revertendi can mislead researchers who encounter the term in a single-domain source. A case discussing animus revertendi in the context of a man's domicile after emigration is doing something conceptually different from a case discussing whether a trained hawk or a swarm of bees has returned to its owner's control. The connecting thread is the same Latin concept — intention or disposition to return determines a continuing legal relationship — but the doctrines are distinct and should not be conflated. Researchers should also distinguish animus revertendi from animus manendi (intention to remain), which is the complementary concept in domicile analysis: the former defeats loss of domicile; the latter establishes a new one.

Why It Matters in Research

This term is deceptively narrow in appearance but surfaces across at least three research areas: domicile and conflict of laws, the law of personal property (particularly animals), and historical criminal law (where domicile bore on venue and jurisdiction). In domicile research, animus revertendi is a factual and often contested question. Historical sources treat it as self-evident that temporary absence preserves domicile, but modern corpus researchers should note that the burden of proof and the evidentiary standards for establishing intent have been developed largely through case law, not statute. Sources citing Rawle and Blackstone are drawing on early Anglo-American domicile doctrine; later treatises and cases substantially elaborated the test. When working through 19th-century materials, watch for the term used interchangeably with animo revertendi (ablative form) — both appear in historical sources and mean the same thing. In the law of animals, the concept is part of the broader ferae naturae doctrine, which distinguishes wild animals (in which no permanent property can be held) from domesticated animals. Animus revertendi carves out a middle category: reclaimed wild animals over which ownership persists only conditionally. This doctrine has obvious relevance to historical disputes over hunting rights, beekeeping, and trained birds of prey, but it also surfaces in modern contexts involving wildlife and escaped exotic animals. Researchers should be aware that American and English cases handling this question vary in how much weight they give to the animal's habit of return versus the owner's intent — the civil law framing emphasizes the animal's disposition; common law courts sometimes shifted focus. The criminal law reference in Black's (citing Russell on Crimes) relates to how domicile affected 19th-century criminal jurisdiction questions, now largely superseded.

Historical Dictionary Support

All three source dictionaries agree on the core: animus revertendi means the intention of returning and operates in both domicile and animal-ownership contexts. Black's and Bouvier's are substantially parallel on the domicile application, citing the same authorities (Rawle, Blackstone's Commentaries, Russell on Crimes, Popham, and Coke). Burrill adds the most value by quoting the civil law maxim at length on the animal rule, emphasizing that ownership persists only while the animal retains the disposition to return — when that disposition ceases, ownership ceases. None of the three dictionaries meaningfully develop the standard of proof or the factual inquiry required to establish animus revertendi in litigation. They state the doctrine but do not grapple with how courts resolved disputed cases. Researchers relying solely on these dictionary entries will have the rule but not the operational doctrine. Burrill is the most analytically useful of the three for the animal-property context; Black's and Bouvier's are more useful as entry points to the domicile case law via their citations.

Jurisdictional Note

The domicile application is broadly accepted across American and English common law jurisdictions, though the precise evidentiary weight given to statements of intent versus objective conduct varies by court. The animal-ownership application draws heavily on civil law sources and is more directly relevant to jurisdictions with civil law influence, though common law courts have adopted the ferae naturae framework generally.
