These sections lay down the rules determining when property (ownership) passes from the seller to the buyer.
1. Principle for Unascertained Goods: Goods Must Be Ascertained (Section 18):
This is a fundamental rule. You cannot transfer ownership of something that is not yet identified. Until the specific goods meant for the buyer are singled out from a larger mass, ownership cannot pass. This is a prerequisite for unascertained goods.
2. Overriding Principle: Property Passes When Intended to Pass (Section 19):
This is the paramount rule. The intention of the parties, as gathered from the terms of the contract, their conduct, and the circumstances of the case [Section 19(2)], governs the timing of property transfer. The subsequent rules (Sections 20-24) are merely guidelines or presumptions to ascertain this intention unless a different intention appears.
Illustration: A contract for a specific car might state that property passes only after full payment. Even if the buyer takes possession, if full payment isn't made, the intention is that property has not passed.
3. Specific Rules for Ascertaining Intention (Sections 20-24):
When the intention is not explicit, these statutory rules provide clarity:
a. Specific Goods in a Deliverable State (Section 20):
This is a common scenario. If the goods are already identified and ready for delivery without any further action by the seller, ownership passes the moment the contract is legally formed, even if payment or actual delivery happens later.
b. Specific Goods to be Put into a Deliverable State (Section 21):
c. Specific Goods in a Deliverable State, When the Seller Has to Weigh, Measure, Test, etc., for Ascertaining Price (Section 22):
Even if the goods are otherwise ready, if the final price needs to be determined by an act of the seller (e.g., weighing a specific quantity of coal, measuring timber), property doesn't pass until that act is done and the buyer has notice.
d. Sale of Unascertained Goods and Appropriation (Section 23):
For unascertained goods, the crucial event for property transfer is unconditional appropriation. This means singling out and setting aside specific goods for the contract with the mutual consent (express or implied, before or after the act) of both parties.
e. Goods Sent on Approval or "On Sale or Return" (Section 24):
In these 'trial' sales, ownership is conditional. It vests in the buyer only upon a positive act of acceptance, an act inconsistent with the seller's ownership, or simply by holding onto the goods beyond a reasonable or agreed period.
4. Reservation of Right of Disposal (Section 25)
Despite delivery to the buyer or a carrier, property does not pass until the seller's conditions are fulfilled. This is a powerful tool for the seller to protect their interests, often by retaining control over documents of title until payment.
Common Scenarios:
Illustration: A sends machinery to B via a shipping company. The bill of lading is made "to the order of A." A sends this bill of lading to B's bank, with instructions to release it to B only upon full payment. Property does not pass to B until B makes the payment and receives the bill of lading.
5. Risk Prima Facie Passes with Property (Section 26)
This is the most crucial "effect" of the transfer of property.
The fundamental principle is that risk follows ownership. The party who owns the goods at the time of accidental loss or damage bears that loss. Physical possession is generally irrelevant to the passing of risk.
Explanation of Proviso: This is an important exception. If the loss or damage occurs because one party caused a delay in delivery, that party bears the risk, irrespective of who owns the goods, provided the loss wouldn't have occurred without that delay.
