Livery of seisin (/ˈsiːzɪn/) is an archaic legal conveyancing ceremony, formerly practised in feudal England and in other countries following English common law, used to convey holdings in property. The term livery is closely related to if not synonymous with delivery used in some jurisdictions in contract law or the related law of deeds. The oldest forms of common law provided that a valid conveyance of a feudal tenure in land required physical transfer by the transferor to the transferee in the presence of witnesses of a piece of the ground itself, in the literal sense of a hand-to-hand passing of an amount of soil, a twig, key to a building on that land, or other token.
