Seller's lien allows retention of goods until price paid or tendered where credit absent, expired, or buyer insolvent. Seller's lien under the Sales of Goods Act confers a right to retain possession of goods until payment or tender of the price where goods were sold without credit, where the credit term has expired, or where the buyer becomes insolvent; this lien may be exercised even when the seller holds the goods as agent or bailee for the buyer.
