Definition
Mesne incumbrances are liens, charges, or encumbrances on real property that were created at an intermediate point in time — that is, after an original mortgage or prior security interest attached, but before a subsequent mortgage or conveyance. The term identifies encumbrances by their chronological position in a chain of title: they are neither the first nor the last, but occupy a middle rank in the priority sequence affecting the property.
In practical terms, a mesne incumbrance is any claim — a judgment lien, a second mortgage, a mechanics' lien, an easement granted by deed, or a tax lien — that burdens land between two other recorded interests. Its significance lies almost entirely in priority: when a senior lienholder forecloses or when title is to be conveyed clear of encumbrances, identifying and disposing of mesne incumbrances determines what claims survive and what claims are extinguished.
Common Language
The word "mesne" carries no meaningful life outside legal usage, and most modern speakers will not recognize it. The related term "incumbrance" (or "encumbrance") does appear in general English, but the compound phrase "mesne incumbrances" is pure legal vocabulary. The COMMON LANGUAGE section is omitted accordingly.
Common Confusion
MESNE INCUMBRANCES vs. MESNE PROFITS: Researchers new to historical sources should not conflate these. Mesne profits are the rents and profits wrongfully received by a person in wrongful possession of land — a separate doctrine with its own remedies. The word "mesne" appears in both phrases with the same meaning (intermediate, in-between), but the legal contexts are entirely different. Historical dictionaries frequently treat mesne profits at length while addressing mesne incumbrances only in passing or by cross-reference, which can mislead a researcher into thinking the two terms are related in substance.
MESNE INCUMBRANCES vs. PRIOR INCUMBRANCES: A prior incumbrance is simply any encumbrance that came before the interest in question. A mesne incumbrance is specifically one that came after the earliest interest but before the latest. The distinction matters in foreclosure proceedings, where a junior mortgagee may be subject to mesne incumbrances that a senior mortgagee's foreclosure would extinguish.
Why It Matters in Research
The term is almost entirely a creature of conveyancing and mortgage practice and appears most densely in English equity cases and American real property treatises of the eighteenth and nineteenth centuries. Several research traps apply:
Spelling variation is significant. Historical sources spell the noun as both "incumbrance" and "encumbrance" — the latter becoming dominant in American usage by the late nineteenth century. A corpus search limited to one spelling will miss a substantial portion of relevant material. Similarly, "mesne" occasionally appears as "mean" in poorly transcribed or phonetically rendered sources.
Priority disputes are the operational context. When researching foreclosure, redemption, or conveyance disputes involving this term, the researcher should expect to find mesne incumbrances discussed alongside marshaling of assets, the doctrine of subrogation, and the order of satisfaction among competing lienholders. These doctrines cluster together in equity opinions and treatises; searching for mesne incumbrances in isolation will produce incomplete results.
The term appears rarely in modern American caselaw. Contemporary practice has largely replaced the phrase with more granular statutory and procedural language around lien priority, title insurance requirements, and foreclosure by advertisement. Researchers working in modern property law will encounter it mainly in older title opinions, historical deed abstracts, and academic commentary on the English roots of American real property law.
English equity practice is the original home of this term. American courts borrowing from equity in the nineteenth century imported both the vocabulary and the underlying priority rules. Researchers working across the Atlantic divide should be alert to procedural differences: English courts of chancery had mechanisms for clearing mesne incumbrances that did not translate identically into American equity or statutory foreclosure practice.
Historical Dictionary Support
The Rapalje & Lawrence entry for "mesne incumbrances" does not appear as a standalone definition in the provided source material. The source material supplied under this headword is, in fact, misattributed content concerning the Statute of Merton (20 Hen. III), mescroyants, and the term "mese" — none of which relate to mesne incumbrances. This is almost certainly an artifact of alphabetical proximity in the original dictionary's organization, where "mesne incumbrances" as a headword fell near these adjacent entries.
This is itself a research warning: historical legal dictionaries organized alphabetically can produce confusing juxtapositions, and digitized or reproduced versions may compound the problem by misattributing content to neighboring headwords. A researcher relying solely on the Rapalje & Lawrence entry as reproduced here would find no substantive definition of the term at all.
The Statute of Merton reference in the source material is not irrelevant to the broader "mesne" cluster — the statute addressed dower, wardship, and related real property matters that intersect historically with incumbrance law — but it defines neither mesne incumbrances nor their priority rules.
Other historical dictionaries, including Bouvier's Law Dictionary and Black's early editions, treat mesne incumbrances more directly in the context of conveyancing and foreclosure, typically emphasizing the time-of-creation test as the governing rule for determining priority among competing liens.
Jurisdictional Note
American states vary in how they rank and extinguish mesne incumbrances in foreclosure proceedings, with some states following strict chronological priority (first in time, first in right) and others applying statutory modifications that elevate certain classes of liens — such as tax liens or mechanics' liens — regardless of recording date. English equity practice, which is the historical baseline for this term, should not be assumed to govern in any American jurisdiction without independent verification of local statutory and case law.
