Seisen (Seizen)

    Possession of real property under claim of freehold estate. This term originally referred to the completion of feudal investiture by which a tenant was admitted into the feud and performed the rights of homage and fealty. Presently it has come to mean possession under a legal right (usually a fee interest). As the old doctrine of corporeal investiture is no longer in force, the delivery of a deed gives seisin in law.
