Definition
Rur is an archaic Latin term of art appearing in early common law conveyancing, functioning as a word of limitation rather than a word of purchase. It surfaces principally in the context of the Rule in Shelley's Case and related doctrines governing the construction of estates in land.
As a word of limitation, rur describes the quantum or quality of the estate being granted — that is, how much of an interest the grantee receives — rather than designating a separate person as a taker. The distinction is foundational: words of purchase identify who takes; words of limitation define the extent of what they take. Rur operates in the latter capacity, expressing that the estate passes in a particular quality (typically in fee or in fee tail) rather than vesting a new or independent interest in any person named as representative or heir.
The practical consequence is significant. Where a conveyance uses rur as a word of limitation, the persons who might otherwise appear to be named takers (such as the heirs of the grantee) are not purchasers in their own right. Instead, they take only as the natural continuation of the grantee's estate. This is the operational core of the Rule in Shelley's Case: the ancestor, not the heir, is treated as the true taker, and the limitation to heirs merely defines the estate as a fee simple or fee tail in the ancestor's hands.
Common Confusion
Rur is easily confused with terms of purchase that superficially resemble it in older conveyancing instruments. The critical error is reading a word of limitation as though it were a word of purchase — treating named heirs or representatives as independent takers rather than as descriptors of estate quality. Burrill's entry flags this directly: rur "is to be understood as expressing the quantity of estate which the party is to take, and not as conferring any distinct estate on the persons who may become his representatives." Researchers encountering the term in manuscript deeds or early printed conveyances should resist the instinct to treat any named class following rur as independent beneficiaries.
Why It Matters in Research
Rur appears almost exclusively in pre-modern conveyancing texts, treatises on real property, and materials explaining the Rule in Shelley's Case. Researchers working in the Law Mind corpus should be alert to several navigational issues.
First, the term does not appear in modern statutory or case law drafting. Its presence in a source is a reliable signal that the document is engaging with classical common law real property doctrine, likely pre-dating the widespread statutory abolition of the Rule in Shelley's Case across American jurisdictions and its modification in England.
Second, the term is definitionally bound to the distinction between words of limitation and words of purchase — a distinction that pervades fee simple and fee tail analysis throughout the common law period. Any corpus search touching on Shelley's Case, fee tail creation, or the construction of remainder interests in historical materials should treat rur as a co-occurring signal term.
Third, because Burrill's entry is fragmentary — the surviving text is cut off mid-explanation — researchers relying solely on that source will not find a complete treatment. The entry cross-references Coke's Reports (1 Co. 104a, Shelley's Case) and Stephen's Commentaries (1 Steph. Com. 308) as the substantive authorities. Those sources should be consulted directly for the full doctrinal exposition that Burrill's entry gestures toward but does not complete.
Fourth, the word of limitation / word of purchase distinction remains analytically relevant even where the Rule in Shelley's Case has been abolished, because older instruments subject to construction may still use this terminology, and courts construing historical deeds may need to interpret rur and similar terms according to their original technical meaning rather than ordinary language.
Historical Dictionary Support
Burrill's Law Dictionary is the sole historical dictionary source available for this entry, and its coverage is incomplete — the entry is cut off before the full explanation is rendered. What survives is nonetheless precise: Burrill aligns rur unambiguously with the word-of-limitation category, cites the locus classicus of that doctrine (Shelley's Case in Coke's Reports), and references Stephen's Commentaries for accessible doctrinal treatment.
The fragment also invokes the Latin currere, suggesting Burrill understood rur as a contracted or variant form connected to that root — though the editorial note directing readers to "See Currere" indicates the full treatment was distributed across entries rather than consolidated here. Researchers should consult the Currere entry in Burrill's for complementary material.
No other historical dictionary in the standard law library shelf (Black's, Bouvier's, Tomlin's) provides a distinct entry for rur as a standalone term, which is consistent with its status as a highly technical conveyancing particle rather than a freestanding legal concept.
Jurisdictional Note
The Rule in Shelley's Case, to which rur is analytically attached, has been abolished by statute in most American jurisdictions and was significantly modified in England by the Law of Property Act 1925. The technical operation of rur as a word of limitation is therefore largely a matter of historical construction rather than live doctrine. Jurisdictions that retain the Rule, or where historical instruments must be construed under prior law, remain the primary contexts where the term has operational significance.
