Definition
An estate pur autre vie (from the Law French meaning "for another's life") is a freehold estate in land measured not by the holder's own life, but by the life of a third person, called the cestui que vie. The holder of the estate — the tenant pur autre vie — possesses the land and enjoys its benefits for as long as that measuring life continues. When the cestui que vie dies, the estate ends, regardless of whether the tenant is still living.
The estate arises most commonly when a life tenant conveys their interest to another person. Because a life tenant can only transfer what they have, the grantee takes the land measured by the grantor's life, not their own. The grantor becomes the cestui que vie; the grantee becomes the tenant pur autre vie.
Common Language
This term has no meaningful common English counterpart. It is pure Law French legal terminology that passed directly into common law property doctrine without acquiring an ordinary English usage. The phrase is sometimes loosely translated as "estate for another's life," which is accurate but rarely used in everyday speech. No COMMON LANGUAGE section applies.
Core Elements
An estate pur autre vie requires three identifying features:
1. A measuring life that is not the tenant's own. The duration of the estate is tied to the life of an identified third person, the cestui que vie.
2. A freehold character. The estate is a recognized freehold interest — the tenant holds real property, not merely a contractual right — but it remains a non-inheritable estate in the classical sense because its duration depends on a life, not a fixed term.
3. Transferability during the measuring life. Unlike a personal life estate, an estate pur autre vie can be conveyed, devised, or assigned. The new holder takes subject to the same measuring life.
Recognized Forms
/SUBTYPES
General Occupancy. At common law, if the tenant pur autre vie died while the cestui que vie was still living, the estate did not pass to the tenant's heirs — it had no natural heir because the measuring life was someone else's. The first stranger who physically occupied the land could claim it as a "general occupant." This was a notorious quirk of the common law.
Special Occupancy. To avoid the chaos of general occupancy, a conveyance could name the tenant pur autre vie's heirs as the successors upon the tenant's premature death. These heirs were "special occupants" with a recognized claim.
Statutory Modification. Most jurisdictions eventually abolished general occupancy by statute, treating the estate as assets of the deceased tenant's estate — transmissible by will or intestacy — for the remaining duration of the measuring life. The Statute of Frauds (1677) addressed this in England; American states followed with analogous statutes.
Why It Matters in Research
Researchers encounter this estate most often in three contexts: historical property disputes, life estate conveyancing chains, and occupancy doctrine.
The general occupancy problem is the central historical trap. Pre-statutory sources — anything before the relevant jurisdiction's occupancy statute — treat the disposition of a tenant pur autre vie's interest at death very differently from post-statutory sources. If a researcher is working with colonial-era American land records or early English property law, the applicable rule depends entirely on whether a statute had abolished general occupancy at that time and place.
The cestui que vie is the measuring pin for the entire estate. Researchers tracing title must identify who the cestui que vie was and establish the date of their death — not the tenant's death — to determine when the estate terminated. This is frequently obscured in deed records, which name the tenant but may not record the measuring life clearly.
The estate pur autre vie sits at the intersection of life estate doctrine and conveyancing law. A researcher following a title chain who sees a life tenant's deed of conveyance must immediately ask: what estate did the grantee receive? The answer is almost always an estate pur autre vie, not a fee simple and not a new life estate measured by the grantee.
Burrill's note that historical sources sometimes called this interest a "term" (terminus) because its duration was bounded is worth flagging: researchers should not assume that every use of "term" in historical sources refers to a leasehold. Context controls.
Historical Dictionary Support
The four source dictionaries are in close agreement on fundamentals. All trace the definition to Blackstone's Commentaries Book II and Littleton's Tenures — the standard common law property authorities — and all define the estate as one held for the life of another person.
Bouvier adds the most substantive analysis of the four, addressing the mechanism by which the estate arises (a life tenant conveying their interest) and the common law consequence of the tenant's premature death — the general occupancy rule. Bouvier's entry appears truncated in the source material but clearly gestures toward the cestui que vie concept and the occupancy problem.
Burrill contributes the useful observation that historical sources sometimes denominated this interest a "term" (terminus) because its duration was bounded, citing Blackstone at 2 Bl. Com. 143. This terminological overlap with leasehold language occasionally creates confusion in historical sources and is not flagged by the other dictionaries.
Black's (both editions) and Burrill's entries are essentially identical in their primary definition — unsurprising given Burrill's influence on Black's — and all three omit the statutory developments that resolved the general occupancy problem. Researchers relying on these dictionaries alone will not be alerted to the jurisdictional and temporal variation in how a tenant pur autre vie's interest passed at death.
None of the source dictionaries address the modern property law treatment, under which the estate survives largely as a historical curiosity except in trusts and estate planning contexts where life estates are still employed.
Jurisdictional Note
American jurisdictions virtually universally abolished general occupancy by statute, treating a deceased tenant pur autre vie's interest as transmissible personal property for the balance of the measuring life. Specific statutory provisions vary by state, and researchers should identify the controlling statute for the relevant jurisdiction and period. In England, the Statute of Frauds (1677) and later legislation accomplished a similar result.
