Definition
A Latin form, used in old English legal records, meaning an assart — a cleared parcel of land converted from forest or waste into arable or productive ground. The term appears in medieval writs, pleadings, and year book entries to describe such a parcel as a discrete unit of property. It is a variant spelling of *assarta* (the plural) or a latinized nominative of the root that also yields the English "assart." The term carries with it whatever rights and obligations attached to assarted land under forest law, including potential liability to the Crown for unlicensed clearing.

Common Confusion
ASSERTA should not be confused with the English verb "assert" or its legal derivative forms (such as an assertion of right or a claim asserted in pleading), though the orthographic resemblance is strong and has led to occasional misreading of medieval manuscript sources. The words share no common derivation for legal purposes. Similarly, researchers should distinguish *asserta* from *assisa* (an assize) and *assertio* (an assertion or claim), both of which appear in Latin legal texts of the same period and can look similar in abbreviated or deteriorated manuscript hands.

Why It Matters in Research
**Identification in sources.** *Asserta* appears almost exclusively in medieval English records — year book reports, forest eyre rolls, common pleas entries, and conveyancing documents from roughly the twelfth through fifteenth centuries. A researcher encountering the term in a transcribed or translated source may not immediately recognize it as a land-description term rather than a verb form ("asserted") or a reference to a claim. Context — particularly the presence of accompanying property rights such as common of turbary, common of pasture, or estovers — is the best guide.
**The Yearbook citation.** Burrill's sole illustrative quotation is drawn from a Michaelmas term Year Book entry from the seventh year of Edward III (1333–34). The phrase *quandam assertam simul cum communia turbariæ* — "a certain assart, together with a common of turbary" — is a typical formula bundling cleared land with an appurtenant right to cut peat. Researchers using year book materials from this period should watch for similar bundled grants, where the nature of the land and the nature of the right attached are described in a single phrase.
**Forest law context.** Assarted land occupied a legally sensitive position under the royal forest system. Unlicensed assarting was a forest offense, and licensed assarts were typically recorded in forest court rolls and exchequer records. When *asserta* appears in a pleading or conveyance, it may signal either a legitimately held cleared parcel or the subject of a dispute over whether proper license was obtained. The Law Mind corpus includes materials touching the forest eyre and forest tenures that provide useful background for interpreting these references.
**Spelling variants.** Latin legal records of this period show considerable spelling instability. Researchers should search under *assarta*, *essarta*, *assartum*, *exsartum*, and the anglicized "assart" when working across different record series. Indexing in older calendars and printed year book editions is inconsistent.

Historical Dictionary Support
Burrill's Law Dictionary provides the only coverage of *asserta* as a discrete headword among standard English legal dictionaries. Burrill correctly identifies it as medieval Latin, glosses it as equivalent to "assart," and supplies the Year Book 7 Edw. III citation. The entry is brief but accurate. What Burrill does not supply — and what historical dictionaries of this class generally omit — is any account of the substantive legal consequences of assarted land: the liability for amercement at the forest eyre, the doctrine that assarts reverted to waste if not continuously cultivated, or the conveyancing conventions by which assarts were described alongside appurtenant rights. Cowell's *Interpreter* and Jacob's *Law Dictionary* cover "assart" in its anglicized form but do not carry the Latin variant as a separate entry. Spelman's *Glossarium* and Du Cange's *Glossarium Mediae et Infimae Latinitatis* offer fuller treatments of the Latin root and its continental variants for researchers needing comparative medieval context.

Jurisdictional Note
*Asserta* and its cognates are specific to the English common law and forest law tradition. The term has no recognized application in Scottish, Irish, or continental legal systems, though analogous concepts (land cleared from forest or waste) exist across medieval European land law under different terminology.
