Definition
A cadastre is an official public record or survey of land within a defined district, documenting the quantity, boundaries, and value of parcels for purposes of taxation and the administration of property rights. Historically, the term appears in American legal sources specifically in the context of Spanish law, where it described an authoritative statement of real property quantities and values used to apportion tax burdens equitably among landowners in a given district.
In broader modern usage, cadastre (or cadastral survey) refers to any systematic, government-maintained inventory of land parcels that maps ownership, extent, and assessed value — the foundational infrastructure of a property tax system and, in many jurisdictions, of land title administration.
Common Language
Modern common usage (Wiktionary): A public survey of land, originally for the purpose of taxation and to create an official register of land ownership; also, the register produced by such surveys, showing details of ownership and value.
Historical common usage (Webster's 1913): Not separately defined; the term was treated as a technical borrowing from French and Spanish administrative law rather than common English vocabulary.
Editorial note: The gap between common and legal usage is narrow but worth flagging. Ordinary usage has broadened the word to encompass any land registry or mapping system, including modern GIS-based cadastral databases. Legal sources from the nineteenth century — and the corpus cases they reference — use the term more narrowly, in the specific context of Spanish colonial or civil-law property administration and its tax-apportionment function. A researcher treating modern "cadastral survey" as synonymous with the historical legal cadastre may import assumptions about comprehensiveness and legal effect that the historical term does not carry.
Why It Matters in Research
The term appears in American legal sources almost exclusively in connection with Spanish land grants and the administration of property in territories formerly under Spanish rule — Louisiana, Florida, Texas, New Mexico, California, and the Southwest generally. Researchers working in those jurisdictions, particularly on land title disputes arising from the transition between Spanish or Mexican sovereignty and United States governance, will encounter cadastre in the context of documentary evidence submitted to confirm or challenge grant boundaries and valuations.
The single citation shared across all four historical dictionary sources — 12 Peters 428 — anchors the legal definition to the U.S. Supreme Court's engagement with Spanish land tenure. Researchers should treat the cadastral record not merely as a tax document but as potential evidence of recognized ownership and boundary, since in civil-law systems the cadastre and the land title system were more closely integrated than their common-law equivalents.
Two practical research traps exist. First, modern cadastral databases maintained by county assessors are sometimes loosely called cadastres, but they carry different legal weight than the official Spanish-law instrument described in the historical dictionaries. Do not assume continuity of legal effect. Second, the term may appear in French-language or Spanish-language source documents in the corpus transliterated or translated inconsistently (cadastro, cadastre, catastro). Searching only the English form will miss relevant materials.
Historical Dictionary Support
Black's (1st and 2nd editions), Bouvier's, and Burrill's are in complete agreement: all four define cadastre identically as an official statement of the quantity and value of real property in a district, made for the purpose of justly apportioning taxes, and all cite the same authority (12 Peters 428, note). This unanimity is itself informative — it signals that the term had a narrow, settled technical meaning in American legal usage, tethered to a specific jurisprudential context rather than general property law.
None of the historical dictionaries address the cadastre's function as a title-registration instrument, which is the dimension emphasized in European civil-law systems and increasingly in modern comparative property law scholarship. This gap matters: researchers relying solely on the historical dictionary definitions may underestimate the evidentiary significance of cadastral records in Spanish land grant litigation, where courts sometimes treated cadastral valuation and survey data as corroborating evidence of a grant's legitimacy and boundaries.
Bouvier's adds a second citation (8 Am. St. Pap. 679), pointing toward the American State Papers as an additional primary source — a useful breadcrumb for researchers tracing cadastral records in the public land history of former Spanish territories.
Jurisdictional Note
The legal significance of cadastral records in American courts is concentrated in states with a Spanish or Mexican land grant history. Louisiana, Florida, Texas, New Mexico, Arizona, and California generated the bulk of U.S. litigation in which cadastral documents were treated as legally operative. Outside those jurisdictions, the term appears rarely in American legal materials and carries no distinct legal weight beyond its descriptive meaning as a property survey or assessment record.
