Definition
BESAEL (also spelled Besayel, Besaiel, Besayle) is a term from Law French denoting a great-grandfather. The feminine form, Besaele, denotes a great-grandmother. In medieval English law, the term gave its name to the writ of besayel, a real action that lay when a person sought to recover land of which his great-grandfather had been seised at the time of his death and which had since passed wrongfully into another's hands.
The writ of besayel (Latin: breve de proavo) was one of a graduated series of ancestral writs corresponding to successive degrees of lineal descent. Burrill records the full sequence: besael, ael, piere, fitz — great-grandfather, grandfather, father, son — and the corresponding feminine line: besaele, aele, mere, file — great-grandmother, grandmother, mother, daughter. Each degree of descent had its own corresponding writ, with the writ of mort d'ancestor serving the nearest degree (parent) and the writs of aiel, besayel, and cosinage extending the remedy progressively further back in the chain of seisin.

Common Confusion
BESAEL, AIEL, AND COSINAGE: These three writs are frequently collapsed in historical sources or treated as interchangeable. They are not. Each writ was calibrated to a specific generational remove. Aiel lay for recovery through a grandfather or grandmother; besayel extended one generation further to the great-grandparent; cosinage (also called nuper obiit in some formulations) served as a catch-all for more remote collateral and lineal ancestors beyond the reach of the named writs. Conflating these terms when reading medieval pleading records or abridgments will produce errors in identifying which action a party pursued and what proof of descent was required.

Why It Matters in Research
Researchers encountering besael in historical sources are almost always looking at one of two things: a kinship term in a genealogical or inheritance passage, or a reference to the writ of besayel in a real actions context. The distinction matters because the same root word does different work depending on context.
The writ of besayel is a dead form of action. It was abolished along with the other ancestral real actions in England by the Real Property Limitation Act 1833 and the subsequent consolidation of real property procedure. American jurisdictions never adopted the writ system in any systematic way, so besayel has no living procedural significance in U.S. law. Researchers working in American sources will encounter the term only in historical commentary, abridgments, or early colonial pleading records that drew on English practice.
The graduated writ system — mort d'ancestor, aiel, besayel, cosinage — reflects a medieval evidentiary logic in which the remoteness of the ancestor whose seisin was claimed affected the difficulty of proof and, consequently, the form of action available. Understanding where besayel sits in that ladder is essential for reading Year Book entries, Fitzherbert's Natura Brevium, or Bracton's treatment of seisin actions. Researchers working in those sources who encounter the writ series without the genealogical vocabulary will lose the structural logic of the entire scheme.
One notable trap: Law French spelling is inconsistent across manuscripts and printed abridgments. Besayel, besaiel, besayle, and besael appear in different sources for the same term. Index searches in corpus materials should account for these orthographic variants. The Latin form breve de proavo may appear in the same passage or in parallel Latin registers covering the same proceedings.

Historical Dictionary Support
Burrill's Law Dictionary is the primary shelf source for this term and provides the most complete treatment available in American legal dictionary literature, including both the genealogical meaning and the writ name, the Latin equivalent breve de proavo, and the full generational sequences in both the male and female lines with citation to Britton. Burrill's entry, though brief, correctly identifies the term as Law French and situates the writ within the ancestral actions framework.
Older English sources — Fitzherbert's Natura Brevium, Coke's commentary, and Bracton — discuss the writ in procedural context but treat besael primarily as a term of art within the writ rather than as a standalone dictionary entry. The genealogical chain Burrill records from Britton (c. 89) is a useful primary anchor for researchers verifying the scope of each ancestral writ.
What historical dictionaries do not adequately address is the comparative relationship between the writ of besayel and the action of cosinage as the scheme broke down in later medieval practice, or the extent to which the writ was actually used as opposed to superseded by more flexible forms of entry. Researchers needing that analysis will need to move beyond dictionary sources into procedural history.

Jurisdictional Note
The writ of besayel was a creature of English common law and has no direct counterpart in American law. The term appears in American legal dictionaries only as historical carryover from the English tradition. Researchers in English legal history should note that the Real Property Limitation Act 1833 ended the practical life of this writ, though it continued to appear in abridgments and commentary well into the nineteenth century.
