An interest in real property held for the duration of the life of some person other than the life tenant (Pur autre vie is a French phrase that literally means "for the life of another"). An estate pur autre vie (also known as pour autre vie) is a form of conventional life estate wherein the duration of the estate is measured not against the life of the life tenant, but against the life of another person specified by the grantor of the estate. An estate pur autre vie is the only life estate that has a right of inheritance: during the life of this other person against whose lifespan the duration of the estate depends, the life tenant's heirs may inherit the property. Once the "other person" is deceased, this right of inheritance ends.
