Definition
"For life" is a durational qualifier used in legal instruments to limit the duration of a right, interest, obligation, or appointment to the span of a particular person's lifetime. It most commonly appears in the following contexts:
1. Property and estates. An estate for life (also called a life estate) grants a person the right to possess and use real property for the duration of their own life, or occasionally for the duration of another's life (an estate pur autre vie). The interest terminates automatically at death — it cannot be devised by will and does not pass through intestate succession.
2. Appointments and tenure. Offices, judgeships, and certain fiduciary appointments may be held "for life," meaning the holder serves until death, resignation, or removal, with no fixed term expiring before death. Federal Article III judges hold office "during good behaviour," a phrase courts and scholars treat as functionally equivalent to tenure for life.
3. Sentences. A sentence of imprisonment "for life" (life sentence) confines a person for the remainder of their natural life, subject to pardon, commutation, or, where available, parole eligibility. Courts distinguish a true life sentence from "life with the possibility of parole."
4. Annuities and income interests. An annuity or income stream granted "for life" terminates at the death of the measuring life, distinguishing it from a term-certain annuity or a perpetual obligation.
In all uses, the essential legal function is the same: a natural human lifetime operates as the measuring event that ends the interest, duty, or status.
Common Language
Modern common usage (Wiktionary): "For the rest of a person's life"; also informally, "very fast or strenuously, as if to save one's life."
Historical common usage (Webster's 1913): The colloquial sense aligns with duration — lasting throughout one's life — used freely in non-legal settings.
The common usage captures the durational idea accurately, but misses the legal precision. In law, "for life" requires identifying whose life is the measuring life — the grantee's own life or a third party's — and this distinction carries significant legal consequences for alienability, valuation, and what happens to the interest at death.
Common Confusion
FOR LIFE vs. IN PERPETUITY: An interest held "for life" ends at death; an interest held "in perpetuity" or in fee simple continues indefinitely and passes to heirs. Researchers encountering older deeds should not assume that a grant lacking the word "heirs" conveys anything more than a life estate — the common law rule required words of inheritance to create a fee simple.
FOR LIFE vs. FOR A TERM OF YEARS: Both are non-freehold or limited interests, but a term of years ends on a fixed date regardless of whether the holder lives; a life interest ends at death regardless of how much calendar time has passed. The distinction affects valuation tables, tax treatment, and future-interest analysis.
FOR OWN LIFE vs. PUR AUTRE VIE: A life estate measured by the grantee's own life is the default. An estate pur autre vie is measured by a third party's life and can survive the holder — it passes to the holder's heirs or devisees if the holder dies before the measuring life. Historical sources sometimes use these phrases interchangeably or imprecisely; researchers should confirm which life is doing the measuring.
Why It Matters in Research
The phrase "for life" operates as a trigger for a cluster of distinct legal consequences, and its significance shifts depending on the era and jurisdiction of the source you are reading.
In early common law property materials, look for whether words of inheritance accompany the grant. Under the pre-statute common law rule, a conveyance without words of inheritance ("to A and his heirs") defaulted to a life estate — meaning the phrase "for life" was often implied rather than expressed. Modern statutes in most U.S. jurisdictions reversed this presumption, so a bare grant now defaults to fee simple. A source's era determines which rule applies.
In corpus research, "for life" appears across property law, criminal sentencing materials, judicial tenure commentary, and trust/annuity instruments. The phrase is used consistently in surface meaning but triggers entirely different bodies of doctrine in each domain. Always anchor the phrase to its subject-matter context before pulling forward analysis from another area.
Valuation is a recurring research issue. Life estates and life-measured annuities are valued using actuarial tables. For federal tax purposes, the IRS publishes tables under the applicable section of the Internal Revenue Code; historical valuations used different tables. If you are researching estate or gift tax treatment of a life interest, confirm which table governed at the relevant date.
For criminal sentencing research, the phrase has been tested in constitutional contexts — particularly whether a mandatory life sentence without parole constitutes cruel and unusual punishment for certain categories of offenders. This is an active area of litigation distinct from the property meaning and should be researched in criminal procedure sources, not estate law materials.
Historical Dictionary Support
Rapalje & Lawrence do not define "for life" as a standalone entry. Instead, they address it through the compound entry ESTATE FOR LIFE, with a citation cluster pointing to mid-nineteenth-century English reporters (Jurist, Manning & Granger, Meeson & Welsby, Scott, and Simons). This framing reflects the era's tendency to treat the phrase as meaningful only when attached to a property interest — the concept of "for life" as a durational qualifier in sentencing or public law appointments receives no parallel treatment in the historical dictionaries consulted.
The citation to 8 Jurist 526 and the surrounding English reports signals that the core questions litigated around estates for life in that period concerned creation — specifically, what language was sufficient to create a life estate versus a fee, and when a life estate arose by implication. These questions are less practically live under modern statutory presumptions but remain critical when interpreting historical instruments.
What the historical dictionaries miss: they do not address the pur autre vie variant with care, they do not treat "for life" in the context of judicial or official tenure, and they predate the constitutional litigation around life sentences entirely.
Jurisdictional Note
U.S. states vary on whether a conveyance without words of inheritance defaults to fee simple or life estate; most modern states and the Uniform Probate Code presume fee simple, but older instruments from states that have not retroactively changed the presumption may still be governed by common law rules. In criminal law, the constitutional limits on life sentences — particularly for juvenile offenders — have developed through U.S. Supreme Court doctrine that binds all states but leaves sentencing structure to individual legislatures.
