Definition
A commission of unlivery was a writ or judicial commission issuing out of the Court of Chancery directing that livery of seisin — the formal act of delivering possession of land — be undone or reversed. Where livery of seisin had been made in error, under fraud, or without proper legal authority, a commission of unlivery authorized an officer to retake possession of the land and restore the parties to their prior positions, effectively unwinding the transfer of seisin that had already taken place.
The term belongs entirely to the vocabulary of medieval English real property law and equity practice. It had no continuing life in American law and was rendered obsolete in England well before the nineteenth century as the ancient ceremonies of livery of seisin were supplanted by deed-based conveyancing and, ultimately, by the Statute of Frauds (1677) and the Real Property Act (1845).

Common Confusion
The term is sometimes loosely associated with the broader concept of rescission or with writs of entry, but it is distinct from both. A writ of entry was an action to recover possession of land wrongfully withheld; a commission of unlivery operated specifically to reverse a completed act of seisin delivery rather than to remedy a wrongful withholding. The confusion arises because both remedies could ultimately restore a prior possessory state, but they operated through different procedural mechanisms and addressed different factual predicates.

Why It Matters in Research
This term will appear almost exclusively in historical English sources — treatises on feudal tenure, early Chancery practice, and antiquarian legal dictionaries — and is essentially absent from American legal materials. Researchers encountering it in primary sources should treat it as a marker of pre-modern English conveyancing practice, signaling that the underlying dispute involves livery of seisin rather than deed-based transfer.
The core research trap is anachronism: applying modern conveyancing concepts to a transaction that operated under entirely different rules. When a historical source mentions a commission of unlivery, the researcher must reconstruct the feudal transfer ceremony itself — the physical delivery of a clod of earth, a twig, or the hasp of a door — to understand what exactly was being reversed.
Because livery of seisin was abolished as a required conveyancing ceremony in England by the mid-nineteenth century, any litigation or instrument referencing this commission in materials after roughly 1850 is either archaic usage, a historical recitation, or a scholarly reference. American jurisdictions never adopted the commission of unlivery as a distinct procedural device, though some early colonial land disputes did involve questions about the validity of seisin deliveries made under English practice.
Corpus researchers working in Chancery records, Year Books, or early equity treatises will find the term embedded in discussions of the Court of Chancery's supervisory authority over the formal acts of common-law conveyancing — an important jurisdictional overlap that generated significant procedural complexity in the sixteenth and seventeenth centuries.

Historical Dictionary Support
Rapalje & Lawrence define a commission of unlivery as a commission issuing out of Chancery to make unlivery of land where livery of seisin had been made without authority or in error. The entry is brief and does not elaborate on the procedural mechanics or the historical frequency of such commissions, which reflects both the term's obscurity and its obsolescence by the time the dictionary was compiled (1883).
No definition appears in Black's Law Dictionary (early editions), Bouvier's Law Dictionary, or other standard American legal dictionaries, which is itself informative: the concept was sufficiently alien to American practice that even the most comprehensive nineteenth-century American dictionaries omitted it. Researchers should not expect to find supporting American authority.
The better historical treatment of the underlying concept — the reversibility of livery of seisin and Chancery's power to intervene — appears in early English equity treatises and in commentary on feudal tenures, including works by Coke and later Blackstone's discussion of seisin in the Commentaries, though neither uses the precise phrase "commission of unlivery" extensively.

Jurisdictional Note
This term has no application in modern American or English law. It belongs exclusively to the historical practice of English Chancery and common-law conveyancing prior to the statutory abolition of livery of seisin as a required formality. Researchers should treat any modern reference as historical or academic in nature.
