The most superior legal title to the ownership of premises  legally referred to as “fee simple absolute in possession”  as opposed to long leasehold (or ground lease) which will often run for 100 years or more, and leasehold (usually the occupational lease interest). For an estate to be a freehold it must possess two qualities: immobility (property must be land or some interest issuing out of or annexed to land); and ownership of it must be of an indeterminate duration.
