What does the legal term "pur autre vie" mean?

The legal term "pur autre vie" translates to "for the life of another." This term is used in property law, particularly in the context of life estates. A life estate pur autre vie allows a person to hold the property for the duration of someone else's life, rather than their own.

For example, if a property is granted to someone "pur autre vie," the grantee has the right to use and benefit from the property as long as a specified individual (the measuring life) is alive. Once that individual passes away, the rights to the property revert to the original grantor or go to another specified party. This concept is important as it signifies the nature of the legal interest in property and the specific life upon which that interest is contingent.

The other options reflect different legal concepts: "in perpetuity" implies an endless duration without limits, "for a specific duration" refers to a definitive time frame, and "on behalf of another" indicates a representative capacity. Each of these has distinct meanings and applications that do not align with the specific nature of a life estate pur autre vie.
