Definition
In Roman law, to transfer property completely to another person — to make that which belongs to oneself belong to another. The term denotes a full and unconditional alienation, without reservation of any interest by the transferor. It appears in classical Latin legal texts, principally the Digest of Justinian, and carries the sense of absolute conveyance rather than partial or encumbered transfer.
Why It Matters in Research
This term will appear almost exclusively in sources dealing with Roman law, civil law jurisdictions, or early common law treatises that drew on Roman foundations. Researchers encountering abalienare in a primary source should treat it as a signal that the surrounding text is engaged with Roman or civil law concepts of ownership and transfer, which do not map cleanly onto common law property categories.
The distinction embedded in the term — transfer without reserve — matters when reading historical sources on conveyancing, succession, and obligations. Roman law recognized gradations of transfer; abalienare sits at the absolute end of that spectrum. A researcher who renders it simply as "alienate" may miss the emphasis on completeness that the word is intended to convey.
Because the term is Latin and appears in Digest citations (Dig. 10.3.14.1; Dig. 32.38.7), researchers working in the Law Mind corpus should expect to find it in glossaries, civil law commentaries, and treatises on Roman property law rather than in common law case reporters or statutes. It has no practical life in modern Anglo-American legal writing.
Historical Dictionary Support
Burrill's Law Dictionary is the sole shelf source covering this term. Burrill derives the word from ab (from) and alienare (to alienate or transfer) and defines it as transferring wholly, or without reserve, citing Calvinus's Lexicon Juridicum and two passages in the Digest. The definition is clean and consistent with classical usage.
No divergence among historical sources needs to be flagged here, as coverage is singular. What Burrill does not supply is any discussion of the procedural or formal contexts in which the term appeared in Roman law — whether in the context of mancipatio, in iure cessio, or other recognized modes of transfer. Researchers seeking that depth will need to move beyond dictionary sources to civil law treatises or direct study of the Digest passages cited.
