Explain the term “Delivery and its form” under the Sale of Goods Act, 1930?

Delivery and its forms: Delivery means voluntary transfer of possession from one person to another [Section 2(2)]. As a general rule, delivery of goods may be made by doing anything, which has the effect of putting the goods in the possession of the buyer, or any person authorized to hold them on his behalf. Forms of delivery: Following are the kinds of delivery for transfer of possession: (a) Actual delivery: When the goods are physically delivered to the buyer. (b) Constructive delivery: When it is effected without any change in the custody or actual possession of the thing as in the case of delivery by attornment (acknowledgement) e.g., where a warehouseman holding the goods of A agrees to hold them on behalf of B, at A’s request. (c) Symbolic delivery: When there is a delivery of a thing in token of a transfer of something else, i.e., delivery of goods in the course of transit may be made by handing over documents of title to goods, like bill of lading or railway receipt or delivery orders or the key of a warehouse containing the goods is handed over to buyer.
