Ownership or ‘in fact’ possession of a freehold estate. Inferred here is an increasing degree of ownership with the passage of time, as the possessor makes productive use of the land. Seizin was originally not an estate, but a way to gain one, as by adverse possession. This is rooted in the Roman concept that whoever worked the land should be its owner.
