Definition
Littus maris (Latin: "shore of the sea") is a term of old English law denoting the sea-shore — specifically, that strip of land lying between the ordinary high and low water marks, overflowed by the sea at common tides. The term defines the boundary of the Crown's littoral title and distinguishes the zone of regular tidal overflow from land that is inundated only exceptionally, as at high spring tides or during storm surges. Land covered only by extraordinary or unusual tides falls outside the technical definition of littus maris and is therefore not subject to the same public or Crown claims as the foreshore proper.
Why It Matters in Research
Researchers encounter littus maris primarily in historical English property disputes involving foreshore rights, tidal boundaries, and the extent of Crown ownership over coastal lands. The term is functionally equivalent to "foreshore" in modern English legal usage, but historical sources use the Latin phrase in a more technically bounded sense — limited to land covered by ordinary tides, not exceptional ones. This distinction carries real consequence: a claim to ownership or use rights over coastal land depends critically on whether that land qualifies as littus maris at all.
The entry in Burrill is truncated, which is an important research caution: the full quotation it draws upon — likely from Hale's De Jure Maris or a closely related source — sets out the ordinary-tide boundary rule in detail. Researchers relying solely on Burrill's compressed entry may miss the doctrinal reasoning behind the limitation. Sir Matthew Hale's De Jure Maris (c. 1667, published posthumously) is the primary treatise authority on this boundary, and any serious research into the historical scope of littus maris should go directly to that source.
In corpus searches, the Latin form is the reliable search term for pre-nineteenth-century English legal materials. By the nineteenth century, English courts and treatises increasingly shifted to "foreshore" and "sea-shore" in English, and the Latin drops away. American materials rarely use littus maris at all; American foreshore doctrine developed along somewhat different lines, with public trust and state-ownership frameworks that diverge from English Crown-title theory. Do not assume that English littoral doctrine maps cleanly onto American coastal property law.
Historical Dictionary Support
Burrill's Law Dictionary provides the sole shelf-source entry. Its definition is brief and its quoted authority appears cut off, but the substance is consistent with the classical understanding: littus maris is the shore between ordinary high and low water, not the land reached only by exceptional tides. The boundary rule — ordinary tides, not spring or storm tides — is the doctrinal core, and Burrill preserves this faithfully even in abbreviated form.
The broader treatise tradition, anchored by Hale's De Jure Maris, establishes that the Crown's title to the foreshore extends to this ordinary-tide zone, with the public retaining rights of navigation and fishing. Later commentators, including Blackstone in his Commentaries, repeat the substance of Hale's analysis without always engaging the Latin terminology directly. Historical dictionaries generally do not improve on Burrill's entry for this term; the concept is better served by going to the primary treatise authorities than by relying on dictionary synthesis.
Jurisdictional Note
The term and its associated doctrine are rooted in English law. In England and Wales, foreshore ownership and tidal boundary questions remain live issues, with the Crown Estate holding presumptive title to the foreshore. In the United States, coastal boundary law is governed by a mix of state law and federal doctrine; the public trust doctrine broadly corresponds to some functions of the littus maris concept but operates under different rules and terminology. Researchers should not treat English littus maris doctrine as direct precedent in American jurisdictions.
