Definition
Animus restituendi is a Latin maxim meaning "the intention of restoring." It describes the mental state of a person who holds property or exercises possession with the purpose of returning it to its rightful owner. The concept operates as a qualifier on possession: one who holds with animus restituendi does not hold adversely, does not assert ownership, and does not acquire possessory rights inconsistent with the owner's title.
The term appears primarily in property law and in the law of theft, where the presence or absence of a specific intent is legally operative. A finder, bailee, or temporary holder who intends to restore property to the true owner holds with animus restituendi. That intent distinguishes lawful temporary possession from wrongful taking.

Common Confusion
Animus restituendi is easily conflated with its doctrinal opposites. Animus furandi is the intent to steal — the intent permanently to deprive an owner of property. Animus domini is the intent to hold as owner, the mental element supporting a claim of adverse possession or ownership. These three terms form a cluster in possession and theft analysis, and distinguishing them is essential when working through historical property or criminal law sources. A passage that discusses "animus" without specifying the type may be ambiguous; the surrounding context — whether the discussion concerns theft, bailment, or adverse possession — will usually identify which form of intent is at issue.

Why It Matters in Research
This term is narrow but technically important in two contexts where intent controls the legal outcome.
First, in the law of larceny and theft, animus restituendi historically operated as a defense. A person who took property intending to return it lacked the animus furandi required for larceny. This doctrine appears in older common law treatises and early criminal law sources. Researchers working with pre-codification criminal law materials will encounter this usage and should note that modern statutory frameworks have largely absorbed or displaced the Latin terminology, so the same concept may appear without the Latin label in twentieth-century sources.
Second, in property and possession analysis — particularly adverse possession and bailment — animus restituendi signals the absence of a hostile or ownership claim. A bailee's possession is not adverse precisely because the bailee holds with the intention of returning. Researchers tracing adverse possession doctrine in historical materials should watch for this term as a marker that the author is distinguishing permissive or custodial possession from possessory claims capable of ripening into title.
The Fleta citation shared by all three source dictionaries (lib. 3, c. 2, § 3) points to a thirteenth-century treatise on English common law. Researchers who encounter this citation should treat Fleta as the deep historical root; the term's appearance in Black's, Bouvier's, and Burrill's carries that lineage forward into nineteenth-century American and English legal vocabulary.
Because the term is Latin and carries a specific technical charge, it tends to appear in formal treatise discussion rather than in case reporters or statutes. Corpus searches should include variant spellings and the English translation ("intention of restoring") to capture sources that paraphrase rather than quote the Latin.

Historical Dictionary Support
Black's, Bouvier's, and Burrill's are in complete agreement, each defining animus restituendi as "the intention of restoring" and each citing Fleta, lib. 3, c. 2, § 3 as the authority. The uniformity across the three dictionaries is notable: there is no divergence in meaning, no competing definition, and no jurisdictional qualification. This suggests the term was treated as settled doctrine with a fixed Roman-law inflected meaning by the time these dictionaries were compiled.
What the historical dictionaries do not provide is operational context — they define the term but do not explain when or how it was invoked, what it defeated, or how courts evaluated the presence or absence of such intent. Researchers should not expect the dictionary entries alone to carry the analytical weight; the dictionaries function here as glossary references pointing back to primary sources like Fleta and to the broader common law treatise tradition on possession and intent.

Jurisdictional Note
The term is rooted in English common law and appears in both English and American legal sources through the nineteenth century. Its practical significance varies depending on how far a jurisdiction's modern statutory law has displaced common law intent analysis in theft and property doctrine. Civil law jurisdictions use analogous concepts under different terminology.
