An owner conveys ownership of his residence to his church but reserves for himself a life estate. The future interest held by the church is a:

When an owner conveys their property to another party while retaining a life estate, the future interest held by the receiving party can be classified as a remainder. In this scenario, the church receives ownership of the residence but will not be able to fully utilize or control the property until the life estate terminates, which will occur upon the death of the life tenant (the owner who reserved the life estate).

A remainder is the legal term used to specify the interest retained by the party that will become the owner of the property after the termination of the life estate. Since the church's interest follows the life estate, it is considered a remainder interest.

This arrangement allows the original owner to continue using the property during their lifetime while ultimately planning for the future transfer of ownership to the church. Other concepts, such as pur autre vie, reversion, and leasehold, do not apply in this case as they define different types of interests or conveyances. Thus, recognizing that the church holds a remainder interest is key to understanding the ownership dynamics surrounding life estates.
