Definition
An agistator is an officer of the English royal forest charged with recording and accounting for cattle pastured (agisted) within the forest. The role was defined by the Charter of the Forest and carried administrative responsibility for tracking livestock permitted to graze on forest land under agistment arrangements. In a secondary sense, the term was also applied to a collector and disburser of taxes levied for the maintenance and repair of sea-walls.
The term is effectively synonymous with agister or agistor and appears in historical sources under all three spellings. It is a creature of English forest administration and has no living counterpart in modern law.
Common Language
Modern common usage (Wiktionary): A rare form of agistor.
Historical common usage (Webster's 1913): See Agister.
Neither general dictionary treats agistator as a word of ordinary English. It entered common reference works only by inheritance from legal and historical usage, and the legal meaning is the only meaningful one.
Recognized Forms
/SUBTYPES
Burrill identifies two distinct applications of the term:
1. Forest Agistator — The officer of the royal forest responsible for keeping account of cattle agisted within forest bounds, operating under the authority of the Charter of the Forest (Carta de Foresta, c. 8). Fleta (lib. 2, c. 41, § 31) provides procedural detail on this officer's duties.
2. Sea-Wall Agistator — A fiscal officer responsible for collecting and expending taxes raised for the upkeep of sea-walls. Kennett's Glossary is the principal source for this usage.
Why It Matters in Research
Agistator is a term a researcher will encounter only in medieval and early modern English sources, primarily in the context of forest law, manorial administration, or land drainage and coastal defense records. Several navigational points matter:
Spelling variation is the primary research trap. The same officer appears as agistator, agistor, agister, and occasionally gyst-taker or guest-taker across different manuscripts and printed authorities. Burrill flags gyst-taker and guest-taker explicitly. Researchers working in original records, plea rolls, or forest eyre materials should search all variants. Cowell's Interpreter and Crompton's Jurisdiction of Courts (fol. 146) are relevant secondary sources from the early modern period; Coke's Fourth Institute (4 Inst. 293) also touches the term.
The sea-wall usage is far less commonly indexed. Researchers tracing the history of drainage law, fen administration, or coastal tax commissions should note that Kennett's Glossary preserves this sense, which is distinct from the forest administration sense and unlikely to appear in forest law indexes.
Agistator has no direct modern legal heir. Where the concept survives at all, it is absorbed into general agistment law (the bailor-bailee relationship for grazing livestock) or into drainage and coastal management statutory frameworks. Equating the historical office with any modern legal concept requires careful qualification.
Historical Dictionary Support
Burrill's Law Dictionary is the only shelf source for this entry, and it is thorough for the term's scope. Burrill correctly identifies the two functional meanings, cites the Charter of the Forest and Fleta for the forest officer role, and directs the reader to Kennett for the sea-wall collector. The cross-reference to Agister/Agistor in Burrill is essential — the substantive legal content is carried under those headings rather than under agistator itself.
What historical dictionaries do not provide is any sustained treatment of how agistators operated procedurally within the forest eyre system, or how the sea-wall tax collection role related to the later drainage commission structures. For that, researchers must go beyond the dictionary shelf to forest law treatises and manorial records directly.
Jurisdictional Note
Agistator is exclusively an English legal term arising from the royal forest system and medieval coastal administration. It has no recognized usage in Scots law, Irish law, or any American jurisdiction. Research touching this term is confined to English legal history.
