Sections 18 to 25 of the Sale of Goods Act, 1930 form the doctrinal heart of the statute. They answer one question — at what moment does ownership in the goods pass from the seller to the buyer? — and in answering it allocate every consequence that flows from ownership: who bears the risk of accidental loss, who can sue for the price, who can resist a third-party claim, and whose insolvency cuts down whose rights. The Act answers the question by a layered scheme. Section 18 SoGA is the threshold bar for unascertained goods. Section 19 SoGA states the master rule of intention. Sections 20 to 24 SoGA supply five default rules where intention has not been declared. Section 25 SoGA preserves the seller's right of disposal. Read together, the cluster organises every commercial sale into one of three boxes — specific goods, ascertained goods, or unascertained and future goods — and assigns each a moment at which ownership crystallises.
The exam-aspirant must approach the cluster with three reference points always in view. First, the threefold goods classification of specific, ascertained, future and unascertained goods on which the cluster operates. Second, the rule that risk prima facie passes with property under Section 26 SoGA, which makes the moment of passing the most consequential moment of the entire transaction. Third, the rule of nemo dat under Sections 27 to 30 SoGA, which decides what happens when a non-owner purports to transfer ownership. The Sections 18 to 25 cluster sits in the middle of those three reference points and is the engine that drives them.
Why the moment of passing matters
Transfer of property in the goods is the essence of a contract of sale. The Act distinguishes property from delivery: property may pass without delivery, and delivery may take place without passing of property. The point of time of passing produces four practical consequences. First, risk prima facie passes with property: if the goods are destroyed or damaged after the moment of passing, the buyer bears the loss; if before, the seller bears it. Second, the buyer who has become owner can exercise proprietary remedies — he can sue for delivery, and if the seller has wrongfully resold the goods to a non-bona-fide buyer, the original buyer can recover the goods from that buyer. Third, the seller cannot ordinarily sue for the price unless property has passed; until then, his remedy lies in damages for non-acceptance. Fourth, the rights of an unpaid seller — lien, stoppage in transit, statutory resale — are calibrated against the moment of passing, as is the question whether a third-party transferee from a person in possession gets a good title under Section 30 SoGA.
Section 18 — the ascertainment threshold
Section 18 SoGA is the foundational bar. It provides that 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 proposition is unqualified. Until the particular goods to be supplied have been physically identified out of the larger pool to which the contract relates, ownership cannot pass however clearly the parties have agreed on quantity, description and price. The Supreme Court applied the rule decisively in Ambalavana Chettiar v. Express Newspaper (AIR 1968 SC 741): a contract first concluded for 415 tons of newsprint then lying in the seller's godown was an unconditional contract for the sale of specific goods in a deliverable state, and property had passed under Section 20 SoGA; but when the parties later varied the contract to 300 tons out of the 415, the variation undid the passing of property because the 300 tons had not been identified or appropriated, and Section 18 stood in the way. The seller's statutory right of resale under Section 54(2) SoGA, which is conditioned on property having passed to the buyer subject to the seller's lien, was therefore not available; the seller's remedy lay in ordinary damages for non-acceptance.
Section 19 — the intention rule
Section 19 SoGA is the master rule for specific or ascertained goods.
The Section is best read as a triple. Sub-section (1) entrenches the autonomy of the parties: the moment of passing is whatever the parties intend. Sub-section (2) tells the court where to look for that intention — contract terms, conduct, surrounding circumstances. Sub-section (3) supplies the default: where the parties have not made their intention clear, the five rules in Sections 20 to 24 SoGA apply by way of presumption. Intention thus controls; the default rules step in only when the parties have left the question open. Sacks v. Tilley (1915) 32 TLR 148 illustrates the priority of intention: diamonds were sent by post under an invoice marked “settled by acceptance”, and the parties had expressly stipulated that property would pass on the buyer's acceptance of the bill. The bill was never accepted; the court held that the ordinary presumption that property passes on dispatch was ousted by the express declaration of intention.
Section 20 — specific goods in a deliverable state
Section 20 SoGA states the first default rule. Where there is an unconditional contract for the sale of specific goods in a deliverable state, the property in the goods passes to the buyer at the moment the contract is made, and it is immaterial whether the time of payment of the price or the time of delivery of the goods, or both, is postponed. Three working concepts populate the rule. “Unconditional” means a contract not subject to any condition precedent or subsequent. “Specific goods” are those identified and agreed upon at the time of the contract — the definition is in Section 2(14) SoGA. “Deliverable state” is defined in Section 2(3) SoGA as such a state of things that the buyer would, under the contract, be bound to take delivery. The companion definitions of buyer, seller, price, property and possession are worked out in the chapter on the definitions in Section 2 SoGA.
The classical illustration is Tarling v. Baxter (1827) 6 B & C 360: a stack of hay was sold on 6 January, the price to be paid on 4 February and the stack to be removed by 1 May. The stack was accidentally destroyed by fire on 20 January. Property had passed at the moment of contract, and the buyer bore the loss — deferred payment and deferred delivery did not delay passing. The very essence of a sale, as opposed to a mere agreement to sell, is precisely this transfer of property; the architecture is set out in the chapter on the contract of sale and the sale-versus-agreement-to-sell distinction under Section 4 SoGA. Dennant v. Skinner (1948) 2 KB 164 makes the same point at an auction: the fall of the hammer was the moment of contract, the contract was unconditional, the goods were specific and in a deliverable state, so property passed at that moment; a later document signed by the buyer purporting to delay passing until cheque clearance was a nullity. Kursell v. Timber Operators (1927) 1 KB 298 is the limit case: a sale of uncut timber, defined to be “all trunks and branches of trees, excluding seedlings and young trees of less than 6 inches in diameter at a height of 4 feet from the ground”, with 15 years allowed to cut and remove, did not satisfy Section 20 because the trees were neither sufficiently identified to be specific goods nor in a deliverable state — the cutting was the buyer's task. Sadhusaran Singh v. W.B. State Electricity Board (AIR 1986 Cal 240) applied Section 20 in favour of a buyer who had won a tender for specified MS rods lying in railway yards: property passed on the acceptance of the tender, and the seller had no right to cancel and resell when the buyer's removal was held up by floods.
Section 21 — something to be done by seller for deliverability
Section 21 SoGA is the second default rule. Where there is a contract for the sale of specific goods, and the seller is bound to do something to the goods for the purpose of putting them into a deliverable state, the property does not pass until that thing is done and the buyer has notice of it. The rule is intuitive. If the seller has yet to bag, polish, pack or assemble the article before the buyer is bound to take it, the article is not in a deliverable state in the buyer's hands, and ownership lingers with the seller until the act is done and the buyer is told of it.
The classical authority is Underwood v. Burgh Castle Brick & Cement Syndicate (1922) 1 KB 343. A condensing engine was sold F.O.R. London. At the time of contract it was installed at the seller's premises. While being dismantled and loaded onto trucks for despatch by rail, it was damaged. The court held that the parties' intention was that property should not pass until the engine was safely placed on rail in London — the seller still had to expend as much money and trouble as the buyer would have to in placing the engine on rail. The loss therefore fell on the seller. Bankes LJ's formulation of “deliverable state” is the textbook gloss: it depends not on the mere completeness of the subject-matter in all its parts, but on the actual state of the goods at the date of the contract and the state in which they are to be delivered by the terms of the contract. Where the goods themselves do not answer to the contract description, the buyer's remedy lies along a different axis — see the chapter on implied conditions of title, description, sample and merchantable quality. Rugg v. Minett (1809) 11 East 210 illustrates the proviso about partial completion: where part of the goods had been put into a deliverable state with the buyer's knowledge but the remainder had not, and the whole lot was destroyed by fire, the loss for the part already in deliverable state fell on the buyer (in whom property had passed) and the loss for the remainder on the seller. Notice to the buyer is essential; whether the notice comes from the seller or from any other source is immaterial.
Section 22 — something to be done by seller for ascertaining price
Section 22 SoGA states the third default rule. Where there is a contract for the sale of specific goods in a deliverable state, but the seller is bound to weigh, test or do some other act or thing with reference to the goods for the purpose of ascertaining the price, the property does not pass until that act or thing is done and the buyer has notice of it. The Section is narrower than Section 21 in two respects: the goods must already be in a deliverable state, and the act in question must go to the ascertainment of price.
Zagury v. Furnell (1809) 2 Camp 240 illustrates the rule. There was a contract for the sale of 289 bales of goat skins, each bale containing five dozens, the price fixed at 5s 6d per dozen. By trade usage the seller was to verify that each bale contained the specified number. Before the seller could do so, the bales were destroyed by fire. The court held that property had not passed because something remained to be done by the seller to ascertain price. The contrasting case is Shoshi Mohan Pal v. Nobo Krishto ILR (1879) 4 Cal 801: a contract for sale of the whole rice in a golah, the buyer to remove after weighing for his own satisfaction, and the seller undertaking to make good any deficiency. Section 22 was not attracted because nothing remained to be done by the seller; the property in the whole quantity passed at the time of contract under Section 20 SoGA. Where price has yet to be ascertained, the buyer's protection often turns on a parallel question of how price is fixed, treated in the chapter on price — ascertainment and earnest money.

Take the civil-law mock →Section 23 — unascertained or future goods and the doctrine of appropriation
Section 23 SoGA is the fourth default rule and the most fact-sensitive of the cluster. It applies to unascertained or future goods. Sub-section (1) provides that 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. The assent may be express or implied, and may be given before or after appropriation. Sub-section (2) supplies a default carrier rule: where the seller delivers the goods to the buyer or to a carrier or other bailee for transmission to the buyer, without reserving the right of disposal, he is deemed to have unconditionally appropriated the goods to the contract.
Four elements must coexist for property to pass under Section 23(1): (a) appropriation of goods to the contract by either party, (b) the appropriation is made with the assent of the other party, (c) the goods appropriated are of the contract description and are in a deliverable state, and (d) the appropriation is unconditional.
Appropriation distinguished from ascertainment
Appropriation is the act of irrevocably attaching particular goods to a particular contract with the mutual consent of the parties. Ascertainment, by contrast, is a unilateral act — the seller alone may set apart the goods. The distinction is doctrinally critical. A seller who merely sets aside 100 bales of cotton in his warehouse out of a larger stock of 5,000 has ascertained, not appropriated, even if the 100 bales are marked with the buyer's name; he can change his mind and use the 100 bales in a different contract. To appropriate, the parties must have intended to attach the contract irrevocably to those goods, so that those goods, and no others, are the subject of the sale. The seller giving notice to the buyer that the bales are ready for delivery, and the buyer assenting that he will take delivery, is the textbook example of appropriation.
Assent to appropriation
Assent may be implied from conduct. Pignataro v. Gilroy & Son (1919) 1 KB 459 is the leading authority. The buyer purchased 140 bags of rice. The seller sent a delivery order for 125 bags and wrote that the remaining 15 should be collected from the warehouse. A month later, when the buyer sent for them, those 15 bags had been stolen. The court held that property had passed: the seller had appropriated the 15 bags in response to the buyer's request for delivery, and the buyer's silence for a month was an implied assent to the appropriation; the goods were therefore at the buyer's risk. Atkinson v. Bell (1828) 8 B & C 277 illustrates the converse: machines were manufactured to order, packed for despatch, and the seller wrote to ask by what conveyance to send them. Before he received a reply he became insolvent. Property had not passed because the buyer had not assented to the appropriation; the seller's remedy was an action for damages for non-acceptance.
Description, deliverable state, unconditional
The goods appropriated must answer to the contract description and must be in a deliverable state. A contract for 100 bags of “first quality wheat” is not satisfied by appropriating 100 bags of second quality. A contract for 1,000 litres of oil packaged in tins of 10 litres is not satisfied by appropriating bulk oil that has yet to be tinned. Appropriation in excess — say 1,200 litres against an order for 1,000 — is not unconditional appropriation of any 1,000 litres because the seller has not identified which 1,000 are to fulfil the contract. The fourth element — unconditional appropriation — brings us to Section 25 SoGA.
Section 25 — reservation of right of disposal
Section 25 SoGA carves an exception out of the appropriation doctrine. Where there is a contract for the sale of specific goods, or where goods are subsequently appropriated to the contract, the seller may, by the terms of the contract or appropriation, reserve the right of disposal of the goods until certain conditions are fulfilled. In such a case, notwithstanding the delivery of the goods to a buyer, or to a carrier or other bailee for transmission to the buyer, the property does not pass to the buyer until the conditions are fulfilled. Two presumptions follow. Where goods are shipped or delivered to a railway for carriage, and by the bill of lading or railway receipt the goods are deliverable to the order of the seller, the seller is prima facie deemed to have reserved the right of disposal. Where the seller draws on the buyer for the price and transmits the bill of exchange together with the bill of lading or railway receipt, the buyer is bound to return the bill of lading or rail receipt if he does not honour the bill of exchange; if he wrongfully retains the bill of lading or rail receipt, property does not pass to him.
The leading Indian authority is Commissioner of Income-tax v. Mysore Chromite Ltd. (AIR 1955 SC 98). The assessee company sold ores by F.O.B. contracts under which the bill of lading was retained by the seller until the bill of exchange was paid; the buyer's right to the documents was conditioned on payment. The Supreme Court held that delivery on board ship was not, in this case, an unconditional appropriation; the seller had reserved the right of disposal, and property in the goods passed only in London where the bill of lading was handed over to the buyer's bank against the bill of exchange. Carona Sahu & Co. v. State of Maharashtra (AIR 1966 SC 115) applied the same principle to a Cochin–Bombay shipment where bills of lading were taken in the seller's name and forwarded through banks for delivery to buyers against payment of price; the property passed in Bombay, not Cochin. Carlos & Co. v. Charles Twigg & Co. (1957) 1 LR 240 went further: an F.O.B. contract for cycles, where the goods were packed for shipment but not yet shipped when the seller became insolvent, did not pass property because the appropriating act — shipment — had not occurred. The reservation of disposal is the seller's primary commercial protection in cross-border or credit sales: it secures payment before ownership. The doctrine of caveat emptor and its statutory exceptions become relevant on the buyer's side of the same transaction; the working scheme is set out in the chapter on the doctrine of caveat emptor under Section 16 SoGA.
Section 24 — sale on approval or on “sale or return”
Section 24 SoGA is the fifth default rule. It applies where goods are delivered to the buyer on approval, on “sale or return” or on other similar terms. The property passes to the buyer (a) when he signifies his approval or acceptance to the seller or does any other act adopting the transaction, or (b) if he does not signify his approval or acceptance to the seller but retains the goods without giving notice of rejection, then on the expiration of the time fixed for the return of the goods or, if no time has been fixed, on the expiration of a reasonable time. Until one of those events occurs, the transaction is an agreement to sell, the seller remains owner, and the risk of loss is on the seller.
Adoption may be by sale, pledge or other dealing inconsistent with the seller's continuing ownership. Kirkham v. Attenborough (1897) 1 QB 201 is the leading case: jewellery was delivered “on sale or return”, the recipient pledged it with a pawn-broker, and Lord Esher MR held that the pledge was an act adopting the transaction, property had thereby passed, and the original seller could only sue for the price — not recover the goods from the pawn-broker. Genn v. Winkel (1912) 107 LT 434 applied the same logic to diamonds passed on through a chain of “sale or return” intermediaries. Where the buyer fails to return within a fixed period, property passes on the expiry of the period: Elphick v. Barnes (1880) 5 CPD 321 — a horse on eight days' trial died on the seventh day without the buyer's fault, and as the trial period had not expired, property had not passed and the seller had to bear the loss.
Putting the cluster together
The five default rules can be reduced to a working flowchart for examination purposes. First, ask whether the goods are unascertained: if yes, Section 18 bars passing until ascertainment, and Section 23 governs the moment of appropriation. Second, ask whether the goods are specific or ascertained: if yes, Section 19 SoGA imports the parties' intention as the master rule. Third, in the absence of express intention, walk through Sections 20 to 24 in order: Section 20 (unconditional contract, specific goods, deliverable state); Section 21 (something for the seller to do for deliverable state); Section 22 (something for the seller to do for ascertainment of price); Section 23 (unascertained or future goods, appropriation by either party with assent of the other); Section 24 (sale on approval). Fourth, at every stage, ask whether the seller has reserved the right of disposal under Section 25 SoGA — a reservation that holds even against an apparent unconditional appropriation. Fifth, once the moment of passing is fixed, run the consequences: Section 26 SoGA on risk; Section 30 SoGA on third-party transferees; Sections 45 to 54 SoGA on remedies for breach of conditions and warranties under Section 12 SoGA and the rights of an unpaid seller. The doctrinal architecture rewards careful reading of all of the Sale of Goods Act notes hub rather than memorisation of the five rules in isolation.
Distinguish from cognate provisions
Three distinctions are worth fixing in mind. First, transfer of property is distinct from delivery: Section 33 SoGA and the chapter on performance of the contract — delivery and acceptance govern the latter. Second, transfer of property is distinct from transfer of title: where the seller has no title at all, Sections 18 to 25 SoGA cannot give the buyer ownership the seller never had — the rule and exceptions of nemo dat quod non habet in Sections 27 to 30 SoGA apply instead. Third, transfer of property must be read alongside the implied condition as to title under Section 14(a) SoGA: a buyer who has paid for goods to which the seller had no title can sue for total failure of consideration on the authority of Rowland v. Divall (1923) 2 KB 500. Where the article is destroyed before the contract is made or before passing of property, the consequences are governed by the chapter on the effect of destruction of goods under Sections 7 and 8 SoGA.
MCQ angle and exam framing
The cluster yields a recurring set of fact-patterns. (a) Specific car sold at auction, cheque dishonoured later — Section 20 and Dennant v. Skinner: property has already passed. (b) Stack of hay or other article destroyed before delivery, payment deferred — Section 20 and Tarling v. Baxter: property has passed, buyer bears the loss. (c) Engine to be loaded onto rail; damaged in loading — Section 21 and Underwood: property has not passed, seller bears the loss. (d) Bales to be counted or weighed by the seller — Section 22 and Zagury v. Furnell: property has not passed. (e) Bags of rice held in seller's warehouse pending buyer's collection, stolen meanwhile — Section 23 and Pignataro v. Gilroy: assent to appropriation may be inferred from silence; property has passed; buyer bears the loss. (f) F.O.B. shipment, bill of lading retained by seller pending payment — Section 25 and Mysore Chromite: seller has reserved right of disposal; property does not pass on shipment. (g) Jewellery on “sale or return”, pledged by recipient — Section 24 and Kirkham v. Attenborough: pledge is an adoption; property has passed; original seller cannot recover. The interlock with the rules of risk under Section 26 SoGA and the exceptions to nemo dat under Sections 27 to 30 SoGA is the most testable axis, and candidates should also be alert to the interaction with the seller's right of stoppage in transit under Sections 50 to 52 SoGA when the buyer becomes insolvent before delivery.
Conclusion
Sections 18 to 25 SoGA are best read as a single integrated module, not as eight separate rules. Section 18 is the threshold; Section 19 is the master rule of intention; Sections 20 to 24 are the five default rules that supply intention where the parties have not declared it; Section 25 is the seller's protection across the entire grid. The five default rules track three working classifications of goods — specific in deliverable state, specific not yet in deliverable state or pending ascertainment of price, unascertained or future, and goods on approval. Each rule is keyed to a particular factual configuration and produces a definite moment of passing. The deepest doctrinal point is the one captured by Section 19 itself: the rules are presumptions of intention, and the parties are free to displace them by clear contrary stipulation. The cases of Sacks v. Tilley, Mysore Chromite, Underwood, Pignataro, Dennant and Kirkham together cover the working ground; mastering them is mastering the cluster.
Frequently asked questions
Why does the Sale of Goods Act fix the moment when property passes?
Because four major consequences turn on it. First, risk prima facie passes with property under Section 26 SoGA — the owner at the moment of loss bears the loss. Second, only the buyer in whom property has vested can sue the seller for delivery or recover the goods from a non-bona-fide third party. Third, the seller can ordinarily sue for the price only after property has passed; until then his remedy is damages for non-acceptance. Fourth, the rights of an unpaid seller and the operation of Section 30 SoGA on third-party transferees are calibrated against the moment of passing.
What is the difference between ascertainment and appropriation under Sections 18 and 23 SoGA?
Ascertainment is a unilateral act — the seller alone may set apart particular goods to fulfil the contract. Appropriation is bilateral — the goods are irrevocably attached to the contract with the assent of the other party. A seller who marks 100 bales out of 5,000 with the buyer's name has ascertained but not appropriated; he can change his mind. Property passes only on appropriation, which requires either the seller's act with the buyer's assent or vice versa. Pignataro v. Gilroy treats silence in the face of a request for delivery as an implied assent to appropriation.
Does property in specific goods pass when the contract is made even if delivery and payment are postponed?
Yes, where Section 20 SoGA applies. The Section provides that in an unconditional contract for the sale of specific goods in a deliverable state, property passes when the contract is made, and it is immaterial whether the time of payment of the price or the time of delivery, or both, is postponed. Tarling v. Baxter is the classical illustration: a stack of hay sold on credit and to be removed later was destroyed by fire before either payment or removal; property had passed at contract, and the buyer bore the loss. Dennant v. Skinner applies the rule to auctions.
When does property pass in F.O.B. contracts where the seller retains the bill of lading?
Not on shipment. Section 25 SoGA permits the seller to reserve the right of disposal until conditions are fulfilled — typically payment of the bill of exchange against which the bill of lading is released. The Supreme Court in Mysore Chromite (1955) held that an F.O.B. shipment under bills of lading retained by the seller did not pass property on board ship; the property passed in London when the bill of lading was handed over to the buyer's bank against the bill of exchange. Carona Sahu (1966) and Carlos & Co. (1957) apply the same principle in different commercial settings.
What happens to the property in goods sent on “sale or return” if the recipient pledges them?
The pledge is an act adopting the transaction within Section 24(a) SoGA, and property passes to the recipient at that moment. Kirkham v. Attenborough (1897) is the leading authority: jewellery delivered on sale or return was pledged to a pawn-broker, and Lord Esher MR held that the original seller could only sue the recipient for the price — he could not recover the goods from the pawn-broker, who had taken in good faith. The same logic applies to a sale on or any other dealing inconsistent with the seller's continuing ownership; once such an act is done, the buyer-on-approval has irrevocably adopted the transaction.
