Definition
An ancient manorial privilege, observed in the counties of Norfolk and Suffolk, by which lords of manors claimed the right to have their tenants' flocks or sheep driven onto the lord's own demesne lands at night to be folded there. The purpose was agricultural improvement: the livestock deposited dung on the lord's land, enriching the soil at the tenant's expense of time and use of animals. Tath was thus a form of compulsory manuring service owed by tenants to their lord, enforced through manorial custom rather than formal contract.
Common Language
Modern common usage (Wiktionary): The dung of livestock left on a field to serve as manure or fertilizer; a piece of ground dunged by livestock; strong grass growing around the dung of cattle.
Historical common usage (Webster's 1913): Webster's 1913 does not record tath as a common English noun. Its entry attributes "tath" to a dialectal verb form unrelated to the legal term.
The common and legal meanings are closely related but distinct in emphasis. The common usage centers on the physical substance — dung and the ground enriched by it. The legal usage focuses on the lord's claimed right to compel the deposit of that substance on his land. A researcher encountering "tath" in a manorial record should not treat it merely as an agricultural description; it signals a claimed seigniorial privilege with legal content and potentially contested boundaries.
Why It Matters in Research
Tath is a term of narrow geographic and historical scope. It appears almost exclusively in records pertaining to Norfolk and Suffolk manors, and its relevance is confined to the medieval and early modern periods of English manorial law. Researchers working with manorial court rolls, extent surveys, or customary tenure documents from these counties may encounter tath as a listed privilege or disputed right.
The key research trap is misreading tath as purely descriptive agricultural language when it is functioning as a legal term of art. In a manorial extent or customary, "the lord claims tath" is a legal assertion of privilege, not a farming note. Disputes over whether tath was validly claimed — and what obligations it imposed on specific tenants — could appear in manorial court proceedings.
Tath connects to the broader category of manorial incidents and customary services, alongside fold-course rights, common of shack, and similar East Anglian agricultural tenure customs. Researchers tracing the legal history of soil improvement obligations or the evolution of manorial demesne management will find tath relevant as one of several compulsory service rights that eroded as customary tenure was commuted or abolished.
No significant statutory treatment of tath as a named right appears in the standard parliamentary record; its survival as a legal term depends almost entirely on manorial custom, Spelman's Glossary, and the legal dictionaries that drew from it.
Historical Dictionary Support
The three source dictionaries — Black's (1st Ed.), Rapalje & Lawrence, and Black's (2nd Ed.) — present virtually identical definitions, all tracing directly to Spelman's Glossary (Spelman, Glossarium Archaiologicum). There is no divergence among them on substance, geographic scope, or historical framing. The uniformity itself is informative: none of the dictionaries drew on independent sources or expanded the definition beyond Spelman's original account, suggesting the term had no active legal life by the time these works were compiled and was preserved as a historical record rather than a working definition.
Spelman remains the primary authority. Researchers needing greater depth should consult the Glossarium Archaiologicum directly, as the legal dictionaries offer no elaboration beyond his account. The dictionaries also do not address whether tath was ever the subject of reported litigation or how disputes over the privilege were resolved in practice — gaps a researcher should not expect these sources to fill.
Jurisdictional Note
Tath is geographically specific to Norfolk and Suffolk in England. It has no recognized counterpart in Scottish, Irish, or American law, and no equivalent doctrine appears to have been transplanted to colonial or common law jurisdictions outside England. Researchers working in any jurisdiction other than historical East Anglian manorial law will not encounter this term as operative legal vocabulary.
