Chapter III of the Act asks one question: when does the property in the goods pass from seller to buyer? Section 18 gives a first, simple answer for unascertained goods: no property passes until they are ascertained. Section 19 gives the governing principle for specific or ascertained goods: property passes when the parties intend it to pass, and the intention is found from the terms of the contract, the conduct of the parties and the circumstances.
In a contract for the sale of unascertained goods, no property is transferred unless and until the goods are ascertained (section 18). For specific or ascertained goods, the property passes at the time the parties intend (section 19(1)). The intention is found from the terms of the contract, the conduct of the parties and the circumstances of the case (19(2)). Unless a different intention appears, sections 20 to 24 are rules for finding that intention (19(3)).
Reading note
This article follows the consolidated text of the Act consulted (latest amendment shown: Act 28 of 1993); later amendments should be checked in the official text. "Property" is defined in section 2(11) as "the general property in goods, and not merely a special property", and "specific goods" in section 2(14) as goods identified and agreed upon when the contract is made. Chapter III follows the sub-heading "Transfer of property as between seller and buyer" and runs from section 18 to section 26. The moment of transfer drives the distinction between a sale and an agreement to sell in section 4, and it should be written down in the contract through careful agreement drafting.
Section 18: unascertained goods
"Where there is a contract for the sale of unascertained goods, no property in the goods is transferred to the buyer unless and until the goods are ascertained."
The section has a plain structure:
- Subject: a contract for the sale of unascertained goods;
- Rule: no property in the goods is transferred to the buyer;
- Duration: "unless and until the goods are ascertained".
The Act does not define "unascertained goods" or "ascertained" in section 2. It uses the contrast with "specific goods", which are identified and agreed upon when the contract is made. So, in this Act, goods not yet identified are the ones section 18 has in mind, and the text does not give a further definition.
Example (the writer's own, not printed in the Act): Fresh Basket agrees to buy "500 kg of basmati rice from the warehouse stock" of Rao Rice Mills, which holds 20 tonnes. No particular 500 kg has been set apart. Until the rice is ascertained, no property in it is transferred to Fresh Basket, however much of the price has been paid. (Whether payment has been made does not appear in the section; the text says nothing about it.)
Section 19(1): the parties' intention for specific or ascertained goods
"Where there is a contract for the sale of specific or ascertained goods the property in them is transferred to the buyer at such time as the parties to the contract intend it to be transferred." Here the starting point is intention. Where goods are specific or ascertained, the parties decide when property passes. The sub-section does not fix a date or an event; it leaves that to the contract.
Section 19(2): how the intention is found
"For the purpose of ascertaining the intention of the parties regard shall be had to the terms of the contract, the conduct of the parties and the circumstances of the case."
Three sources:
- The terms of the contract. A clause may say that property passes on payment, on delivery, on inspection or on any other event.
- The conduct of the parties. What they do after the contract, for example how they treat the goods or the documents, may show the intention.
- The circumstances of the case. The surrounding facts.
The wording "regard shall be had to" means all three are looked at. The text does not rank them.
Example (the writer's own): The contract between Das Furnishings and Mukherjee Hotels for a specific, identified suite of furniture says: "Property in the furniture passes to the buyer on payment of the full price." The terms of the contract show the intention. If no such clause existed, the conduct of the parties (say, the buyer already treating the furniture as its own) and the circumstances would be examined.
Section 19(3): the rules in sections 20 to 24
"Unless a different intention appears, the rules contained in sections 20 to 24 are rules for ascertaining the intention of the parties as to the time at which the property in the goods is to pass to the buyer."
This is the link to the next group of sections. Sections 20 to 24 are described as rules for ascertaining the intention. They apply "unless a different intention appears". So a different intention shown by the contract displaces them. The subject of each of those sections is as follows in the Act's own headings:
| Section | Heading (as printed) |
|---|---|
| 20 | Specific goods in a deliverable state |
| 21 | Specific goods to be put into a deliverable state |
| 22 | Specific goods in a deliverable state, when the seller has to do anything thereto in order to ascertain price |
| 23 | Sale of unascertained goods and appropriation |
| 24 | Goods sent on approval or "on sale or return" |
Sections 20 to 22 are discussed in the next article, section 23 in a later one, and section 24 in another.
Sections 18 and 19 compared
| Point | Section 18 | Section 19 |
|---|---|---|
| Kind of goods | unascertained | specific or ascertained |
| Rule | no property passes until goods are ascertained | property passes when the parties intend |
| Role of intention | not mentioned | central, found by terms, conduct and circumstances |
| Link to later sections | sets the first step | sections 20 to 24 are rules to find intention, unless a different intention appears |
Together the two sections work in order. First ask: are the goods ascertained? If not, section 18 says no property passes. If they are specific or ascertained, ask: when did the parties intend the property to pass?
Why the moment matters
Section 4 divides a contract of sale into a sale (property transferred) and an agreement to sell (transfer at a future time or on a condition). Section 26 later says that, unless otherwise agreed, goods remain at the seller's risk until the property is transferred to the buyer and are at the buyer's risk once it is. Section 8 turns on the risk passing. So the moment of transfer carries real consequences, and the safest course is to state it in the contract.
Drafting pointers
- Identify the goods in the contract by lot number, serial number or location. This moves them from unascertained to ascertained.
- Say when property passes and on what event.
- Keep conduct consistent with the clause: if the clause says property passes on payment, do not hand over documents of title on a different footing without recording why.
- Remember the closing words of 19(3): the rules of sections 20 to 24 yield to a different intention.
Need help fixing when ownership passes?
If your contract does not say when ownership of the goods moves to the buyer, or if it says so in an unclear way, we can draft or revise the agreement with identified goods, a stated transfer event and matching risk terms.
Key takeaways
- No property passes in unascertained goods until they are ascertained (section 18).
- For specific or ascertained goods, property passes when the parties intend (section 19(1)).
- The intention is found from the terms of the contract, the conduct of the parties and the circumstances of the case (section 19(2)).
- Sections 20 to 24 are rules for finding the intention, unless a different intention appears (section 19(3)).
- Identify the goods and name the moment of transfer in the contract.
