Definition
A Law French term meaning "creeks of the sea." In historical English legal usage, sauces der mer referred to small coastal inlets, tidal creeks, or narrow arms of the sea — the kinds of waterways that featured in disputes over riparian rights, fishing privileges, coastal jurisdiction, and the boundaries of royal or manorial grants touching tidal waters.
Why It Matters in Research
Researchers working in early English land records, manorial surveys, coastal grants, or admiralty-adjacent property disputes may encounter this term in its Law French form or in anglicized variants. The term is geographically descriptive rather than doctrinally technical — it functions as a boundary marker or property descriptor rather than as a legal category with its own body of rules.
The primary research trap is mistaking the term for a broader legal concept when it is in fact a locational descriptor embedded in a grant or survey. Its significance in any given document depends entirely on what legal rights or boundaries were being defined by reference to the creek in question. Fishing rights, toll collection, wreck of the sea, and flotsam jurisdiction all turned on precise descriptions of coastal geography in medieval and early modern English law, making accurate identification of terms like this essential to interpreting the scope of a grant.
Burrill's entry is brief and cross-referential, directing readers to Kelham's dictionary of Norman French legal terms. Researchers needing fuller context should consult Kelham directly alongside the primary record at issue. The term does not appear to have generated independent doctrinal development and is not a term of art in the way that, for example, terms defining tidal ownership boundaries (such as the foreshore or the mark of high tide) became in later common law.
Historical Dictionary Support
Burrill's Law Dictionary provides the sole dictionary authority identified for this term, rendering the entry in translation ("Creeks of the sea") and attributing the gloss to Kelham. Burrill's treatment is characteristically terse for geographical Law French terms of this kind — his dictionary catalogues rather than analyzes them. No doctrinal commentary accompanies the entry.
The placement of the entry in Burrill alongside adjacent terms (SAULX for willows or sallows; SAUMA for a load or pack; SAUMARIUS for a sumpter-horse) is notable: these are all practical, descriptive Law French and Law Latin terms from old records rather than terms with developed legal doctrine. This confirms that sauces der mer belongs to the vocabulary of medieval record-keeping and property description, not to the analytical vocabulary of common law doctrine.
Researchers should not expect coverage of this term in later dictionaries such as Black's Law Dictionary, which generally omits Law French geographical descriptors in favor of terms with continued doctrinal relevance.
Jurisdictional Note
The term is specific to historical English legal records and the Law French tradition of medieval and early modern England. It has no application in American law and is unlikely to appear outside of English manorial, coastal, or admiralty-adjacent records predating the widespread displacement of Law French from legal documents.
