What is a distinguishing feature of a Pur Atre Vie life estate?

A distinguishing feature of a Pur Atre Vie life estate is that it allows for the rights and benefits of the life estate to be transferred to the life tenant’s heirs while they are still alive. This means that although the life estate is based on the life tenant's lifespan, the interest in the property can be passed down, thus providing certain benefits to their heirs during the life tenant's lifetime.

In a Pur Atre Vie life estate, the life tenant holds a property interest for the duration of someone else's life, which is different from a conventional life estate where the interest only pertains to the life tenant themselves. As a result, heirs can benefit from the property while the life tenant is still alive, which does not occur in many other types of property interests.

The other options highlight different aspects of life estates but do not capture the unique characteristic of Pur Atre Vie life estates, specifically regarding the ability to pass the interest to heirs while the life tenant is still living.
