General purpose of this lecture is to explain on Transfer of Title, in terms of Business Law. If transfer of title by non owner, the act would be; estoppels, sale by mercantile agent, sale by one or several joint owner, sale of goods obtained under voidable agreement, sale by the seller in possession of goods after sale, buyer in possession of goods over which the seller has some rights and an unpaid seller. When the Seller Has Imperfect Title; should remind that; a void title is no title at all. If seller sells stolen property, title does not pass to buyer – Buyer beware!
