Definition
Letters of bailery are formal instruments by which authority is delegated to act in a legal capacity over property or persons, in one of two distinct senses depending on jurisdiction and context:
1. In general legal usage (analogous to letters of administration): Documents issued by a court or competent authority conferring upon a named individual the powers and responsibilities of a bailie or administrator over an estate or specified property — broadly comparable in function to letters testamentary or letters of administration. The rights and duties of those holding letters of bailery in this sense track closely with those of personal representatives in estate administration.
2. In Scots law specifically: Commissions issued by a heritable proprietor (an owner of heritable, i.e., real, property under Scots law) authorizing a baron-bailie to hold courts, appoint subordinate officers, and exercise jurisdictional functions within the proprietor's lands. This usage reflects the older feudal structure of Scottish land tenure and local justice, in which private landholders exercised quasi-judicial authority over their estates.

Common Confusion
The term "bailie" underlying this phrase carries different meanings across legal traditions. In Scots law, a bailie (or baillie) was a municipal magistrate or a judicial officer appointed by a landowner — a figure with jurisdictional authority. This differs sharply from the English legal concept of a bailee (one who receives property in bailment) and from the French-derived "bailiff." Researchers encountering "letters of bailery" in Scottish sources should not conflate the role with the English bailee or with English bailiff commissions; the Scottish instrument conferred court-holding and administrative authority rooted in feudal land tenure, not mere custody of property.

Why It Matters in Research
This term appears rarely in modern legal sources and is largely obsolete in active practice, which makes encountering it in historical records particularly disorienting. A researcher working through Scots legal materials from the medieval period through the early modern era will find letters of bailery embedded in the feudal court system — the baron courts — which persisted formally in Scotland until the Heritable Jurisdictions (Scotland) Act 1746 abolished most heritable jurisdictions following the Jacobite rising. After 1746, the practical use of the Scottish sense of letters of bailery effectively collapsed.
For researchers working with estate administration materials in other common law contexts, the first sense of the term (analogous to letters of administration) appears in older American and English treatises and court records. The Bouvier's cross-reference to letters testamentary and to administration signals that this usage functioned as a regional or period variant for instruments now universally described as letters of administration or letters testamentary. Searching historical probate records, particularly from jurisdictions with Scottish legal influence or from earlier American colonial and early national periods, may surface this terminology where modern indexes would use "administration" or "executor."
The primary research trap is treating the two senses as interchangeable. The estate-administration sense and the Scots feudal commission sense are distinct instruments with different legal foundations. Context — particularly whether the source is a probate/estate record or a Scots land tenure document — determines which sense applies.

Historical Dictionary Support
Bouvier's is the primary historical source offering definition here, and it is sparse. The entry for the estate-administration sense does little more than redirect the reader to letters testamentary and to the administration entry, treating letters of bailery as a functional equivalent rather than a term requiring independent analysis. This approach reflects Bouvier's general method of cross-referencing synonymous or near-synonymous instruments rather than elaborating distinctions.
The Scots law sense receives its own brief entry in Bouvier's, correctly identifying the heritable proprietor as the issuing authority and the baron-bailie as the recipient. Bouvier's does not, however, address the historical context of Scottish heritable jurisdictions or the effect of the 1746 Act, leaving the researcher without guidance on when and why this instrument ceased to have practical force.
Neither sense appears in later consolidated legal dictionaries with any meaningful elaboration, reflecting the term's decline from active usage. Researchers relying solely on post-nineteenth-century legal dictionaries may find no entry at all.

Jurisdictional Note
The Scots law sense is specific to Scotland's feudal land tenure system and is effectively a historical artifact following the abolition of heritable jurisdictions in 1746. The estate-administration sense, where it appears, tracks the law of the jurisdiction issuing the letters — functionally equivalent to letters of administration and governed by the same substantive rules applicable to personal representatives in that forum.
