In a pur autre vie estate, who gains possession of the property if the beneficiary dies before the measuring life?

In a pur autre vie estate, the interest is measured by the life of a person other than the grantee, known as the measuring life. If the beneficiary of the estate dies while the measuring life is still alive, the property does not revert to the original grantor or the state; instead, it becomes part of the estate of the deceased beneficiary. This means that the deceased's estate can pass on the possessory rights to heirs or beneficiaries specified in a will or under the laws of intestacy.

The rationale behind this is that the pur autre vie estate is meant to provide a life estate until the measuring life ends. Since the measuring life has not yet died, the beneficiary's rights do not extinguish upon their death; those rights simply become a part of their estate, which will ultimately be handled in accordance with the wishes of the deceased or the laws governing inheritance. This provides continuity in the ownership or use of the property until the measuring life concludes.
