Appropriation is a critical step for the transfer of ownership of unascertained goods. According to Section 23 of the Sale of Goods Act, 1930, where there is a contract for the sale of unascertained or future goods by description, and goods of that description and in a deliverable state are unconditionally appropriated to the contract, either by the seller with the assent of the buyer, or by the buyer with the assent of the seller, the property in the goods thereupon passes to the buyer.
Key elements of valid appropriation:
- Goods must conform to description: The goods must be of the type and quality specified in the contract.
- Deliverable state: The goods must be ready for delivery.
- Unconditional: The appropriation must not be subject to any conditions.
- Assent: Both parties must assent to the appropriation. This assent can be express or implied, and given before or after the appropriation.
Examples include setting aside specific goods, marking them, or delivering them to a carrier for transmission to the buyer without reserving the right of disposal.
