What term refers to the ownership structure that includes fee simple subject to condition subsequent?

The term that refers to the ownership structure that includes fee simple subject to condition subsequent is best categorized as a type of Freehold Estate. Freehold estates are characterized by the ownership of real property for an indefinite duration, in contrast to non-freehold estates, which convey possession but not ownership for a limited time.

A fee simple subject to condition subsequent is a form of freehold estate that allows the original grantor to retain some control over the property. Specifically, it means that ownership is granted under certain conditions, and if those conditions are violated, the grantor has the right to retake possession of the property. This type of ownership reflects the permanent and inheritable nature of freehold estates, highlighting not only the rights of ownership but also the conditions attached to that ownership.

In contrast, non-freehold estates tend to involve leasing and renting arrangements with specific time frames but do not grant full ownership to the tenant. Shared ownership can pertain to various forms of co-ownership, such as joint tenancy or tenancy in common, while easements refer specifically to the right to use another's land for a particular purpose. These terms do not capture the essence of an ownership structure where conditions affect the title, which is inherent in fee simple subject to condition subsequent
