Definition
The Statutum Hibernie de Co Hæredibus (Latin: "Statute of Ireland Concerning Heirs") is a brief medieval royal directive addressed to the king's justices in Ireland, instructing them on the proper legal procedure to be followed in a specific matter of inheritance or succession in which they had expressed doubt. It is recorded as the third public act in the historical statute book of England and represents an early example of royal instruction functioning as quasi-legislative guidance to judicial officers in a colonial dependency.
The document's precise operative scope is narrow: it does not establish broad legal principle but rather resolves a procedural or substantive uncertainty that had arisen in Irish judicial practice, directing the justices how to proceed when uncertainty existed regarding heirs or heritable rights.

Why It Matters in Research
Researchers working in early English or Anglo-Irish legal history will encounter this statute as a catalog entry in older compilations of medieval statutes rather than as a living legal instrument. Several navigational points are worth noting.
First, the title itself is frequently truncated or abbreviated in historical sources, appearing variously as "Stat. Hib." or simply by its position ("the third public act") rather than by full name. Researchers searching statute rolls or indexes should anticipate inconsistent titling.
Second, the document's classification as a "statute" reflects the elastic usage of that term in medieval practice. This was not legislation in the modern sense — it was a royal instruction or rescript that acquired statutory standing by virtue of its inclusion in the official statute book. This matters because it shapes how the document should be read: as direction from the Crown to its officers, not as a general rule of law addressed to subjects.
Third, the Irish dimension is significant. Medieval Anglo-Irish law developed under the peculiar condition that English statutes did not automatically extend to Ireland — a point that became a prolonged constitutional controversy culminating centuries later in Poynings' Law (1494) and beyond. The Statutum Hibernie de Co Hæredibus belongs to the earlier period when royal instructions to Irish justices served as the principal vehicle for legal direction, before parliamentary channels became the dominant mechanism. Researchers tracing the development of Anglo-Irish constitutional subordination should note this statute as an early data point in that longer narrative.
Fourth, the statute's resolution of a doubt about inheritance procedure connects it to the broader medieval project of systematizing heirship rules — a project that included more prominent instruments such as the Statute of Westminster II (1285) and the rules governing fee tails and remainder interests. Researchers should resist the temptation to read this brief directive in isolation; it belongs to a cluster of medieval enactments addressing succession uncertainty.

Historical Dictionary Support
Bouvier's Law Dictionary provides the principal historical treatment available, and it is brief. Bouvier identifies the document as the third public act in the statute book and characterizes it as a royal instruction to justices in Ireland addressing a point of doubt, citing Reeve's History of English Law (volume 1, page 259) as authority.
Bouvier's entry is minimal by design — this was a minor medieval instrument, not a cornerstone of English common law development — and the cross-reference to Reeve is the critical pointer for researchers seeking more than a catalog description. John Reeve's History of the English Law Before the Time of Edward I (various editions from the late eighteenth and early nineteenth centuries) remains the primary secondary source for contextualizing instruments of this type within the broader development of early English and Anglo-Irish legal administration.
What the historical dictionaries collectively omit is any sustained analysis of the statute's substantive content — what the doubt was, how it was resolved, and what practical effect the instruction had on Irish judicial practice. This gap reflects the document's obscurity and the limited survival of contemporary commentary. Researchers requiring substantive analysis must go directly to the primary source and to Reeve's historical treatment rather than relying on dictionary coverage.

Jurisdictional Note
This statute pertains specifically to Ireland under the jurisdiction of the English Crown during the medieval period. It has no operative force in modern law in any jurisdiction and is relevant solely as a historical document in the study of medieval Anglo-Irish legal administration.
