What are the rights of an unpaid seller in the sale of goods act?

Under the Sale of Goods Act, an unpaid seller has several key rights, including the right to retain possession of the goods until payment is received, the right to stop goods in transit if the buyer defaults, and the right to resell the goods after providing notice to the buyer. Additionally, the seller may have a claim for damages against the buyer for breach of contract. These rights help protect the seller's interests when payment has not been made.
