What must a life estate pur autre vie be measured by?

A life estate pur autre vie is a type of life estate that is specifically measured by the life of someone other than the grantee. This means that while the grantee holds the estate, their interest in the property lasts as long as the specified third party is alive.

The purpose of a life estate pur autre vie is to provide a way for individuals to grant property rights to someone else while connecting the rights to the life of another individual. This is particularly relevant in planning scenarios where property ownership might be transferred based on the longevity of someone else's life, such as in estate planning or when taking care of an individual who may need support.

In this context, the life of the grantee has no bearing on the life estate's duration; it can extend beyond the life of the grantee and depend on the life of the designated third party. Other options, such as a predetermined number of years or the lifespan of the property, do not correctly represent how a life estate pur autre vie operates, which fundamentally hinges on the life of that third party.
