[from Norman French: autre vie, other life]
An interest in property for the lifetime of someone else. If A is given property for B's life, A is the tenant pur autre vie and will hold the property during the lifetime of B [the cestui que vie]. If A dies before B, the persons entitled under A's will or on his intestacy will take the interest for the remainder of B's life; if B dies before A, A's interest thereupon terminates. The interest is a kind of life interest and an estate of freehold, i.e. it could be inherited; since 1925 it has been an equitable interest only.
