Definition
An allodial estate under French feudal law — land held in absolute ownership, free from feudal tenure, obligations, or service. An aleuvu was distinguished from a benefice or fief, which was held conditionally from a superior lord. The holder of an aleuvu owed no homage, fealty, or service as a condition of ownership; title rested in the holder outright rather than being derived from or subordinate to a superior.

Common Confusion
ALEUVU vs. ALLODIUM: These terms describe the same underlying concept — land held in absolute ownership free of feudal obligation — but aleuvu is the French feudal form and allodium is the Latin and common law form. Researchers should not treat them as separate legal institutions; the distinction is terminological and linguistic, not substantive. In Law Mind sources, allodium and allodial carry the developed doctrine; aleuvu is an entry point that should redirect research toward those terms.
ALEUVU vs. BENEFICE/FIEF: The contrast Black's draws is essential. A benefice or fief was conditional tenure — land granted by a lord in exchange for service, with title remaining ultimately in the grantor. An aleuvu inverted that structure entirely. The practical legal difference affected inheritance, alienability, and liability for feudal dues.

Why It Matters in Research
This term appears almost exclusively in sources dealing with French feudal land law and its historical influence on property systems in territories once under French legal governance — including parts of Louisiana, Quebec, and French colonial holdings. Researchers encountering the term in historical documents should treat it as a marker of allodial tenure and cross-reference it against the broader allodium/fee simple distinction, which carried forward into modern common law property concepts in modified form.
The term is archaic and narrow. It will not appear in modern American or English case law under this spelling. If you encounter it in a historical deed, colonial land grant record, or feudal treatise, it signals that the land described was claimed to be held free of feudal incident — a claim with potentially significant legal consequences in disputes over title, inheritance, and encumbrance in territories transitioning from French to common law systems.
Do not expect this term in English-language legal dictionaries beyond Black's second edition or in specialized historical treatments of French property law. Its absence from later editions and from most common law dictionaries reflects its obsolescence outside narrow historical research contexts.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the sole entry in the Law Mind corpus, defining aleuvu concisely as a French feudal allodial estate distinguished from a benefice. The entry is functional but minimal, offering no elaboration on the mechanics of allodial tenure under French customary law or the procedural significance of the distinction.
No other corpus sources address this term. Researchers needing depth beyond Black's brief note should consult treatises on French customary law and feudal land systems directly. The term's absence from later editions of Black's and from English common law dictionaries is itself informative: the concept migrated into Anglo-American law not under this French term but under the Latin-derived allodium and its English derivative allodial, where it received substantially more treatment.
