So an unpaid seller means the person who has sold the goods for a price and the payment of price has not been made to him or the instrument which was given to him has been dishonored in its maturity. Such seller is known as an unpaid seller.


According to section 46, the seller who has sold the property in goods to the buyer has the following rights against the goods when the whole of the price or a part of the price is not paid by the buyer;

Where the goods have been sold for credit and the terms Of credit have expired,
Where the buyer becomes insolvent,
If the seller has made partial delivery of the goods, he may exercise his right of lien over the undelivered goods unless he has waived his right of lien.

The unpaid seller who has parted with the possession of goods has the right of stopping them in transit that is to say he may resume possession of the goods as long as they are in the course of transit, and may retain them until payment or tender of the price. In order to do so, the following conditions must be fulfilled.
