The Unpaid Seller's Lien under Sections 47 to 49 of the Sale of Goods Act, 1930: When the Lien Arises, Its Possessory Nature, Part Delivery, and How the Lien Is Lost

The unpaid seller's lien is the simplest of his rights against the goods: he keeps them until he is paid. What makes it remarkable is that the goods may already belong to the buyer. Ownership has passed, but the seller still has possession, and the Act lets him hold on to another person's property as security for the price. Because the right depends entirely on possession, it is lost the moment possession goes, and Sections 48 and 49 work out what happens when the seller delivers part of the goods, and when the lien comes to an end.

When the lien arises, what part delivery does to it, and the three ways it is lost

1. When the Lien Arises: Section 47

Section 47, Sale of Goods Act, 1930

(1) Subject to the provisions of this Act, the unpaid seller of goods who is in possession of them is entitled to retain possession of them until payment or tender of the price in the following cases, namely: (a) where the goods have been sold without any stipulation as to credit; (b) where the goods have been sold on credit, but the term of credit has expired; (c) where the buyer becomes insolvent.

(2) The seller may exercise his right of lien notwithstanding that he is in possession of the goods as agent or bailee for the buyer.

No credit agreed. The price is payable at once, and the seller need not part with the goods until it is paid or tendered.
Credit expired. A seller who gave credit must deliver during the credit period, but if the goods are still with him when it expires, the lien revives.
Buyer insolvent. The lien arises even during a credit period, because the basis on which credit was given has failed. Insolvency has the commercial meaning given by Section 2(7A).
Possession as agent or bailee. Section 47(2) makes clear that the seller does not lose the lien merely because he is holding the goods on the buyer's behalf, for example storing them after a sale.

2. The Nature of the Right

It is possessory. It gives a right to retain, not to sell. A power of resale exists only within Section 54.
It is for the price only, not for other debts owed by the buyer, and not for storage charges, although those may be recoverable under Section 44.
It attaches to the goods in the seller's possession, even though property has passed to the buyer.
Where property has not passed, the seller does not need a lien; he simply withholds delivery under Section 46(2), a right co-extensive with the lien.

3. Part Delivery: Section 48

Section 48, Sale of Goods Act, 1930

Where an unpaid seller has made part delivery of the goods, he may exercise his right of lien on the remainder, unless such part delivery has been made under such circumstances as to show an agreement to waive the lien.

📖 Grice v. Richardson, (1877) 3 App Cas 319 (PC)

Facts: Sellers of tea delivered part of the consignment to the buyer and were not paid for the rest. They retained the undelivered portion, and the buyer's assignees in insolvency claimed it, arguing that by delivering part the sellers had given up their lien.

Held: The sellers were entitled to retain the undelivered tea. Part delivery does not of itself destroy the lien over the remainder; it does so only where the circumstances show an agreement to waive the lien over the whole.

Ratio: Part delivery leaves the lien intact over the goods still held, unless it was made in circumstances showing that the seller gave up his lien over the whole consignment.

4. How the Lien Is Lost: Section 49

Section 49, Sale of Goods Act, 1930

(1) The unpaid seller of goods loses his lien thereon: (a) when he delivers the goods to a carrier or other bailee for the purpose of transmission to the buyer without reserving the right of disposal of the goods; (b) when the buyer or his agent lawfully obtains possession of the goods; (c) by waiver thereof.

(2) The unpaid seller of goods, having a lien thereon, does not lose his lien by reason only that he has obtained a decree for the price of the goods.

Delivery to a carrier ends the lien, but it may be replaced by the right of stoppage in transit under Section 50 if the buyer is insolvent. A seller who reserves the right of disposal under Section 25 keeps control.
Lawful possession by the buyer ends the lien. Possession obtained wrongfully, for example by removing the goods without the seller's consent, does not.
Waiver may be express or implied, as by agreeing to give credit after the sale, or by assenting to a sub-sale in a way that renounces the lien.
A decree for the price does not end the lien. The seller may hold the goods while enforcing his decree, since the decree does not give him the money.

📖 Valpy v. Gibson, (1847) 4 CB 837

Facts: Goods were sold and delivered to the buyer's shipping agents for shipment. At the buyer's request the goods were returned to the sellers for repacking, and while they were with the sellers the buyer became insolvent. The sellers claimed a lien.

Held: The sellers had no lien. The goods had been delivered to the buyer's agents, so the buyer had lawfully obtained possession and the lien had gone. When the goods came back to the sellers, they held them as the buyer's agents for repacking, not as unpaid sellers, and the lost lien did not revive.

Ratio: Once the buyer has lawfully obtained possession, the lien is gone, and a seller who later receives the goods back in a different capacity does not regain it.

5. The Position Stated Shortly

Section 47: an unpaid seller in possession may retain the goods until paid, where no credit was agreed, where the credit term has expired, or where the buyer is insolvent.
The lien survives even where the seller holds as agent or bailee for the buyer.
It is possessory, is for the price only, and gives no power of sale except under Section 54.
Section 48: part delivery leaves the lien over the remainder, unless it shows an agreement to waive.
Grice v. Richardson: delivery of part of the tea did not defeat the lien over the rest.
Section 49: the lien is lost by delivery to a carrier without reserving disposal, by the buyer lawfully obtaining possession, or by waiver.
Valpy v. Gibson: a lien once lost does not revive when the goods come back for another purpose.
A decree for the price does not by itself destroy the lien.
