Definition
A paired conveyancing device in which two parties execute reciprocal leases of the same property to one another, each lease serving a distinct legal function. The transaction works as follows: the first party (A) grants a lease — the demise — to the second party (B), typically at a nominal or token rent. B then immediately redemises, or leases back, the same property to A for a shorter term at a real, substantial rent. The result is that A retains possession and pays rent to B, while B holds a reversionary interest supported by a recognized leasehold title.
The device was a workaround. By clothing what was economically a mortgage or security arrangement in the technical dress of a lease and lease-back, the parties could accomplish ends that the rigid rules of common-law conveyancing might otherwise obstruct — particularly in the creation of rent charges, the securing of annuities, or the establishment of interests that would have been vulnerable to challenge under other forms.

Common Confusion
DEMISE AND REDEMISE vs. DEMISE (standalone): The word "demise" alone is used broadly in property law to mean any lease or conveyance, and in admiralty it designates a specific class of bareboat charter in which the charterer takes full operational possession of a vessel. The compound term "demise and redemise" refers specifically to the mutual, back-and-forth lease structure described above — not simply any lease, and not the admiralty demise charter. Researchers encountering "demise" in isolation should determine from context whether the term refers to a general conveyancing act, the specific paired device, or an admiralty instrument before applying secondary sources interchangeably.

Why It Matters in Research
This term is almost exclusively a historical research term. Demise and redemise as an active drafting technique belongs to the common-law property era; modern practitioners have little occasion to use it, and modern statutes generally do not invoke the form. Researchers will encounter it primarily in:
1. Pre-twentieth-century deed and lease records, especially English and early American conveyances involving rent charges, annuities, or informal security arrangements over land.
2. Older treatises on real property and conveyancing — Blackstone, Cruise's Digest, Preston on Conveyancing — where the device is explained as part of the infrastructure of leasehold practice.
3. Cases construing historical instruments where the question is whether a demise-and-redemise structure created a true landlord-tenant relationship, a security interest, or something else. Courts occasionally had to decide whether the nominal lease in the pair was legally operative or merely ceremonial.
The principal trap for corpus researchers is that the two words rarely appear as a rigid compound. A document may describe the transaction discursively — "A did demise unto B... and B did redemise unto A" — without using the compound noun form that a keyword search would catch. Boolean searches should be constructed to capture the component verbs in proximity, not just the phrase as a unit.
The admiralty connection deserves a flag: the bareboat or "demise" charter in modern maritime law descends conceptually from the same root word but operates under an entirely different body of doctrine. Cross-contamination of secondary sources between land-based demise-and-redemise scholarship and admiralty demise-charter scholarship will produce errors.

Historical Dictionary Support
Black's Law Dictionary reproduces the core structure with economy: A leases to B at a peppercorn rent; B leases back to A for a shorter term at a real rent. The citation to Jacob and Whishaw points to the English legal dictionary tradition — both Jacob's Law Dictionary and Whishaw's New Law Dictionary were standard English reference works of the eighteenth and early nineteenth centuries, confirming that this was a recognized term of art in English conveyancing before it crossed into American usage.
What Black's does not address, and what historical sources generally treat incompletely, is the functional question: why bother? The answer lies in the technical requirements of older English property law. Certain interests — rent charges, for instance — required a reversion or a term out of which they could be carved. The demise-and-redemise structure manufactured a leasehold framework that could support those interests even when the underlying arrangement was economically more like a mortgage or annuity. The formalism was the point.
Historical sources are also silent on the device's decline. The simplification of conveyancing law through the English Law of Property Act 1925 and parallel American statutory reforms eliminated most of the technical pressures that made demise and redemise necessary. The form persisted in older precedent books long after its practical utility had lapsed.

Jurisdictional Note
The device originated in English common law and was adopted in American jurisdictions that followed common-law conveyancing traditions. Because conveyancing formalities are governed by state law, any surviving legal effect of a historical demise-and-redemise instrument will depend on the property law of the jurisdiction where the land is situated. Researchers working with instruments from Louisiana or other civil-law-influenced jurisdictions should be particularly cautious about assuming common-law doctrine applies.
